Here is a matrix of mmap possibilities: mmap private not fixed mmap private fixed at somewhere currently unmapped mmap private fixed at somewhere already mapped mmap shared not fixed mmap shared fixed at somewhere currently unmapped mmap shared fixed at somewhere already mapped For private mappings, we should verify that changes cannot be read() back from the file, nor mmap's back from the file at a different address. (There have been systems where private was not correctly implemented like the infamous i386 svr4.0, and systems where the VM page cache was not coherent with the file system buffer cache like early versions of FreeBSD and possibly contemporary NetBSD.)

Options to configure: --prefix=/path to specify the directory prefix for installing xinetd. Check the README file for a description of the following options: --with-libwrap=[path] to specify that you would like libwrap compiled in. --with-loadavg Other options, such as what signals do what, where the default paths point for things like the config file and the debug dump file, default limitations, etc can all be configured in xinetd/config.h Please take a look at the config file before using it. A default config file is in xinetd/sample.conf. I can almost guarantee you'll have problems if you use the default config file. xconv.pl is a perl script that will convert your old inetd.conf file to xinetd.conf syntax.

Any line whose first non-white-space character is a '#' is considered a comment line. Empty lines are ignored. .LP The file contains entries of the form: .RS .nf .ft B .sp service { .RS .ft B ... .I "..." .RE } .ft R .fi .RE .LP The assignment operator, .I assign_op, can be one of .B '=', .B '+=', .B '-='. The majority of attributes support only the simple assignment operator, .B '='. Attributes whose value is a set of values support all assignment operators. For such attributes, .B '+=' means adding a value to the set and .B '-=' means removing a value from the set. A list of these attributes will be given after all the attributes are described. .LP Each entry defines a service identified by the \fIservice_name\fP. The following is a list of available attributes: .TP 17 .B id This attribute is used to uniquely identify a service. This is useful because there exist services that can use different protocols and need to be described with different entries in the configuration file. By default, the service id is the same as the service name. .TP .B type Any combination of the following values may be used: .RS .TP 12 .B RPC if this is an RPC service .TP .B INTERNAL if this is a service provided by \fBxinetd\fP. .TP .B TCPMUX/TCPMUXPLUS if this is a service that will be started according to the RFC 1078 protocol on the TCPMUX well-known port. See the section describing TCPMUX services below. .TP .B UNLISTED if this is a service not listed in a standard system file (like .I /etc/rpc for RPC services, or .I /etc/services for non-RPC services). .RE .TP .B flags Any combination of the following flags may be used: .RS .TP 12 .B INTERCEPT Intercept packets or accepted connections in order to verify that they are coming from acceptable locations (internal or multi-threaded services cannot be intercepted). .TP .B NORETRY Avoid retry attempts in case of fork failure. .TP .B IDONLY Accept connections only when the remote end identifies the remote user (i.e. the remote host must run an identification server). This flag applies only to connection-based services. This flag is ineffective if the .B USERID log option is not used. .TP .B NAMEINARGS This will cause the first argument in "server_args" to be argv[0] when executing the server, as specified in "server". This allows you to use tcpd by putting tcpd in "server" and the name of the server in "server_args" like in normal inetd. .TP .B NODELAY If the service is a tcp service and the NODELAY flag is set, then the TCP_NODELAY flag will be set on the socket. If the service is not a tcp service, this option has no effect. .TP .B KEEPALIVE If the service is a tcp service and the KEEPALIVE flag is set, then the SO_KEEPALIVE socket flag will be set on the socket. If the service is not a tcp service, this option has no effect. .TP .B NOLIBWRAP This disables internal calling of the tcpwrap library to determine access to the service. This may be needed in order to use libwrap functionality not available to long-running processes such as xinetd; in this case, the tcpd program can be called explicitly (see also the NAMEINARGS flag). For RPC services using TCP transport, this flag is automatically turned on, because xinetd cannot get remote host address information for the rpc port. .TP .B SENSOR This replaces the service with a sensor that detects accesses to the specified port. NOTE: It will NOT detect stealth scans. This flag should be used only on services that you know you don't need. When an access is made to this service's port, the IP Address is added to a global no_access list. This causes all subsequent accesses from the originating IP address to be denied access until the deny_time setting expires. The amount of time spent on this list is configurable as the deny_time attribute. The SENSOR flag will also cause xinetd to consider the server attribute to be INTERNAL no matter what is typed on the same line. Another important thing to remember is that if the socket_type is set to stream, then the wait attribute should be set to no. .TP .B IPv4 Sets the service to be an IPv4 service (AF_INET). .TP .B IPv6 Sets the service to be an IPv6 service (AF_INET6), if IPv6 is available on the system. .TP .B LABELED The LABELED flag will tell xinetd to change the child processes SE Linux context to match that of the incoming connection as it starts the service. This only works for external tcp non-waiting servers and is an error if applied to an internal, udp, or tcp-wait server. .TP .B REUSE The REUSE flag is deprecated. All services now implicitly use the REUSE flag. .RE .TP .B disable This is boolean "yes" or "no". This will result in the service being disabled and not starting. See the DISABLE flag description. .RE .TP .B socket_type Possible values for this attribute include: .RS .TP 12 .I stream stream-based service .TP .I dgram datagram-based service .TP .I raw service that requires direct access to IP .TP .I seqpacket service that requires reliable sequential datagram transmission .RE .TP .B protocol determines the protocol that is employed by the service. The protocol must exist in .I /etc/protocols. If this attribute is not defined, the default protocol employed by the service will be used. .TP .B wait This attribute determines if the service is single-threaded or multi-threaded and whether or not xinetd accepts the connection or the server program accepts the connection. If its value is \fIyes\fP, the service is single-threaded; this means that \fBxinetd\fP will start the server and then it will stop handling requests for the service until the server dies and that the server software will accept the connection. If the attribute value is \fIno\fP, the service is multi-threaded and \fBxinetd\fP will keep handling new service requests and xinetd will accept the connection. It should be noted that udp/dgram services normally expect the value to be yes since udp is not connection oriented, while tcp/stream servers normally expect the value to be no. .TP .B user determines the uid for the server process. The user attribute can either be numeric or a name. If a name is given (recommended), the user name must exist in .I /etc/passwd. This attribute is ineffective if the effective user ID of \fBxinetd\fP is not super-user. .TP .B group determines the gid for the server process. The group attribute can either be numeric or a name. If a name is given (recommended), the group name must exist in .I /etc/group. If a group is not specified, the group of \fIuser\fP will be used (from .I /etc/passwd). This attribute is ineffective if the effective user ID of \fBxinetd\fP is not super-user and if the \fBgroups\fP attribute is not set to 'yes'. .TP .B instances determines the number of servers that can be simultaneously active for a service (the default is no limit). The value of this attribute can be either a number or .B UNLIMITED which means that there is no limit. .TP .B nice determines the server priority. Its value is a (possibly negative) number; check nice(3) for more information. .TP .B server determines the program to execute for this service. .TP .B server_args determines the arguments passed to the server. In contrast to \fBinetd\fP, the server name should \fInot\fP be included in \fIserver_args\fP. .TP +.B libwrap overrides the service name passed to libwrap (which defaults to the server name, the first server_args component with NAMEINARGS, the id for internal services and the service name for redirected services). This attribute is only valid if xinetd has been configured with the libwrap option. .TP .B only_from determines the remote hosts to which the particular service is available. Its value is a list of IP addresses which can be specified in any combination of the following ways: .RS .TP 5 .B a) a numeric address in the form of %d.%d.%d.%d. If the rightmost components are 0, they are treated as wildcards (for example, 128.138.12.0 matches all hosts on the 128.138.12 subnet). 0.0.0.0 matches all Internet addresses. IPv6 hosts may be specified in the form of abcd:ef01::2345:6789. The rightmost rule for IPv4 addresses does not apply to IPv6 addresses. .TP .B b) a factorized address in the form of %d.%d.%d.{%d,%d,...}. There is no need for all 4 components (i.e. %d.%d.{%d,%d,...%d} is also ok). However, the factorized part must be at the end of the address. This form does not work for IPv6 hosts. .TP .B c) a network name (from .I /etc/networks). This form does not work for IPv6 hosts. .TP .B d) a host name. When a connection is made to xinetd, a reverse lookup is performed, and the canonical name returned is compared to the specified host name. You may also use domain names in the form of .domain.com. If the reverse lookup of the client's IP is within .domain.com, a match occurs. .TP .B e) an ip address/netmask range in the form of 1.2.3.4/32. IPv6 address/netmask ranges in the form of 1234::/46 are also valid. .RE .TP .B "" Specifying this attribute without a value makes the service available to nobody. .TP .B no_access determines the remote hosts to which the particular service is unavailable. Its value can be specified in the same way as the value of the \fBonly_from\fP attribute. These two attributes determine the location access control enforced by \fBxinetd\fP. If none of the two is specified for a service, the service is available to anyone. If both are specified for a service, the one that is the better match for the address of the remote host determines if the service is available to that host (for example, if the \fBonly_from\fP list contains 128.138.209.0 and the \fBno_access\fP list contains 128.138.209.10 then the host with the address 128.138.209.10 can not access the service). .TP .B access_times determines the time intervals when the service is available. An interval has the form \fIhour:min-hour:min\fP (connections .I will be accepted at the bounds of an interval). Hours can range from 0 to 23 and minutes from 0 to 59. .TP .B log_type determines where the service log output is sent. There are two formats: .RS .TP .B SYSLOG " \fIsyslog_facility [syslog_level]\fP" The log output is sent to syslog at the specified facility. Possible facility names include: .I daemon, .I auth, .I authpriv, .I user, .I mail, .I lpr, .I news, .I uucp, .I ftp .I "local0-7." Possible level names include: .I emerg, .I alert, .I crit, .I err, .I warning, .I notice, .I info, .I debug. If a level is not present, the messages will be recorded at the .I info level. .TP .B FILE " \fIfile [soft_limit [hard_limit]]\fP" The log output is appended to \fIfile\fP which will be created if it does not exist. Two limits on the size of the log file can be optionally specified. The first limit is a soft one; .B xinetd will log a message the first time this limit is exceeded (if .B xinetd logs to syslog, the message will be sent at the .I alert priority level). The second limit is a hard limit; .B xinetd will stop logging for the affected service (if the log file is a common log file, then more than one service may be affected) and will log a message about this (if .B xinetd logs to syslog, the message will be sent at the .I alert priority level). If a hard limit is not specified, it defaults to the soft limit increased by 1% but the extra size must be within the parameters .SM LOG_EXTRA_MIN and .SM LOG_EXTRA_MAX which default to 5K and 20K respectively (these constants are defined in \fIxconfig.h\fP). .RE .TP .B log_on_success determines what information is logged when a server is started and when that server exits (the service id is always included in the log entry). Any combination of the following values may be specified: .RS .TP 12 .B PID logs the server process id (if the service is implemented by \fBxinetd\fP without forking another process the logged process id will be 0) .TP .B HOST logs the remote host address .TP .B USERID logs the user id of the remote user using the RFC 1413 identification protocol. This option is available only for multi-threaded stream services. .TP .B EXIT logs the fact that a server exited along with the exit status or the termination signal (the process id is also logged if the .B PID option is used) .TP .B DURATION logs the duration of a service session .TP .B TRAFFIC logs the total bytes in and out for a redirected service. .RE .TP .B log_on_failure determines what information is logged when a server cannot be started (either because of a lack of resources or because of access control restrictions). The service id is always included in the log entry along with the reason for failure. Any combination of the following values may be specified: .RS .TP 12 .B HOST logs the remote host address. .TP .B USERID logs the user id of the remote user using the RFC 1413 identification protocol. This option is available only for multi-threaded stream services. .TP .B ATTEMPT logs the fact that a failed attempt was made (this option is implied by all others). .RE .TP .B rpc_version determines the RPC version for a RPC service. The version can be a single number or a range in the form \fInumber\fP-\fInumber\fP. .TP .B rpc_number determines the number for an .I UNLISTED RPC service (this attribute is ignored if the service is not unlisted). .TP .B env The value of this attribute is a list of strings of the form 'name=value'. These strings will be added to the environment before starting a server (therefore the server's environment will include \fBxinetd\fP's environment plus the specified strings). .TP .B passenv The value of this attribute is a list of environment variables from \fBxinetd\fP's environment that will be passed to the server. An empty list implies passing no variables to the server except for those explicitly defined using the .I env attribute. (notice that you can use this attribute in conjunction with the .I env attribute to specify exactly what environment will be passed to the server). .TP .B port determines the service port. If this attribute is specified for a service listed in .I /etc/services, it must be equal to the port number listed in that file. .TP .B redirect Allows a tcp service to be redirected to another host. When xinetd receives a tcp connection on this port it spawns a process that establishes a connection to the host and port number specified, and forwards all data between the two hosts. This option is useful when your internal machines are not visible to the outside world. Syntax is: redirect = (ip address) (port). You can also use a hostname instead of the IP address in this field. The hostname lookup is performed only once, when xinetd is started, and the first IP address returned is the one that is used until xinetd is restarted. The "server" attribute is not required when this option is specified. If the "server" attribute is specified, this attribute takes priority. .TP .B bind Allows a service to be bound to a specific interface on the machine. This means you can have a telnet server listening on a local, secured interface, and not on the external interface. Or one port on one interface can do something, while the same port on a different interface can do something completely different. Syntax: bind = (ip address of interface). .TP .B interface Synonym for bind. .TP .B banner Takes the name of a file to be splatted at the remote host when a connection to that service is established. This banner is printed regardless of access control. It should *always* be printed when a connection has been made. \fBxinetd\fP outputs the file as-is, so you must ensure the file is correctly formatted for the service's protocol. In paticular, if the protocol requires CR-LF pairs for line termination, you must supply them. .TP .B banner_success Takes the name of a file to be splatted at the remote host when a connection to that service is granted. This banner is printed as soon as access is granted for the service. \fBxinetd\fP outputs the file as-is, so you must ensure the file is correctly formatted for the service's protocol. In paticular, if the protocol requires CR-LF pairs for line termination, you must supply them. .TP .B banner_fail Takes the name of a file to be splatted at the remote host when a connection to that service is denied. This banner is printed immediately upon denial of access. This is useful for informing your users that they are doing something bad and they shouldn't be doing it anymore. \fBxinetd\fP outputs the file as-is, so you must ensure the file is correctly formatted for the service's protocol. In paticular, if the protocol requires CR-LF pairs for line termination, you must supply them. .TP .B per_source Takes an integer or "UNLIMITED" as an argument. This specifies the maximum instances of this service per source IP address. This can also be specified in the defaults section. .TP .B cps Limits the rate of incoming connections. Takes two arguments. The first argument is the number of connections per second to handle. If the rate of incoming connections is higher than this, the service will be temporarily disabled. The second argument is the number of seconds to wait before re-enabling the service after it has been disabled. The default for this setting is 50 incoming connections and the interval is 10 seconds. .TP .B max_load Takes a floating point value as the load at which the service will stop accepting connections. For example: 2 or 2.5. The service will stop accepting connections at this load. This is the one minute load average. This is an OS dependent feature, and currently only Linux, Solaris, and FreeBSD are supported for this. This feature is only avaliable if xinetd was configured with the -with-loadavg option. .TP .B groups Takes either "yes" or "no". If the groups attribute is set to "yes", then the server is executed with access to the groups that the server's effective UID has access to. Alternatively, if the \fBgroup\fP attribute is set, the server is executed with access to the groups specified. If the groups attribute is set to "no", then the server runs with no supplementary groups. This attribute must be set to "yes" for many BSD systems. This attribute can be set in the defaults section as well. .TP .B mdns Takes either "yes" or "no". On systems that support mdns registration of services (currently only Mac OS X), this will enable or disable registration of the service. This defaults to "yes". .TP .B umask Sets the inherited umask for the service. Expects an octal value. This option may be set in the "defaults" section to set a umask for all services. xinetd sets its own umask to the previous umask OR'd with 022. This is the umask that will be inherited by all child processes if the umask option is not used. .TP .B enabled Takes a list of service ID's to enable. This will enable only the services listed as arguments to this attribute; the rest will be disabled. If you have 2 ftp services, you will need to list both of their ID's and not just ftp. (ftp is the service name, not the ID. It might accidentally be the ID, but you better check.) Note that the service "disable" attribute and "DISABLE" flag can prevent a service from being enabled despite being listed in this attribute. .TP .B include Takes a filename in the form of "include /etc/xinetd/service". The file is then parsed as a new configuration file. It is not the same thing as pasting the file into xinetd.conf where the include directive is given. The included file must be in the same form as xinetd.conf. This may not be specified from within a service. It must be specified outside a service declaration. .TP .B includedir Takes a directory name in the form of "includedir /etc/xinetd.d". Every file inside that directory, excluding files with names containing a dot ('.') or ending with a tilde ('~'), will be parsed as xinetd configuration files. The files will be parsed in alphabetical order according to the C locale. This allows you to specify services one per file within a directory. The .B includedir directive may not be specified from within a service declaration. .TP .B rlimit_as Sets the Address Space resource limit for the service. One parameter is required, which is either a positive integer representing the number of bytes to set the limit to (K or M may be used to specify kilobytes/megabytes) or "UNLIMITED". Due to the way Linux's libc malloc is implemented, it is more useful to set this limit than rlimit_data, rlimit_rss and rlimit_stack. This resource limit is only implemented on Linux systems. .TP .B rlimit_cpu Sets the maximum number of CPU seconds that the service may use. One parameter is required, which is either a positive integer representing the number of CPU seconds limit to, or "UNLIMITED". .TP .B rlimit_data Sets the maximum data size resource limit for the service. One parameter is required, which is either a positive integer representing the number of bytes or "UNLIMITED". .TP .B rlimit_rss Sets the maximum resident set size limit for the service. Setting this value low will make the process a likely candidate for swapping out to disk when memory is low. One parameter is required, which is either a positive integer representing the number of bytes or "UNLIMITED". .TP .B rlimit_stack Set the maximum stack size limit for the service. One parameter is required, which is either a positive integer representing the number of bytes or "UNLIMITED". .TP .B deny_time Sets the time span that access to all services on all IP addresses are denied to someone that sets off the SENSOR. The unit of time is in minutes. Valid options are: FOREVER, NEVER, and a numeric value. FOREVER causes the IP address not to be purged until xinetd is restarted. NEVER has the effect of just logging the offending IP address. A typical time value would be 60 minutes. This should stop most DOS attacks while allowing IP addresses that come from a pool to be recycled for legitimate purposes. This option must be used in conjunction with the SENSOR flag. .LP You don't need to specify all of the above attributes for each service. The necessary attributes for a service are: .sp 1 .PD .1v .RS .TP 18 .B socket_type .TP .B user (non-\fIinternal\fP services only) .TP .B server (non-\fIinternal\fP services only) .TP .B wait .TP .B protocol (\fIRPC\fP and \fIunlisted\fP services only) .TP .B rpc_version (\fIRPC\fP services only) .TP .B rpc_number (\fIunlisted\fP RPC services only) .TP .B port (\fIunlisted\fP non-RPC services only) .RE .PD .LP The following attributes support all assignment operators: .sp 1 .PD .1v .RS .TP 18 .B only_from .TP .B no_access .TP .B log_on_success .TP .B log_on_failure .TP .B passenv .TP .B env (does not support the .B '-=' operator) .RE .PD .LP These attributes can also appear more than once in a service entry. The remaining attributes support only the .B '=' operator and can appear at most once in a service entry. .LP The configuration file may also contain a single defaults entry that has the form .LP .RS .nf .ft B defaults { .RS .ft B = ... .I "..." .RE .ft B } .ft R .fi .RE .LP This entry provides default attribute values for service entries that don't specify those attributes. Possible default attributes: .sp 1 .PD .1v .RS .TP 18 .B log_type (cumulative effect) .TP .B bind .TP .B per_source .TP .B umask .TP .B log_on_success (cumulative effect) .TP .B log_on_failure (cumulative effect) .TP .B only_from (cumulative effect) .TP .B no_access (cumulative effect) .TP .B passenv (cumulative effect) .TP .B instances .TP .B disabled (cumulative effect) .TP .B enabled (cumulative effect) .TP .B banner .TP .B banner_success .TP .B banner_fail .TP .B per_source .TP .B groups .TP .B cps .TP .B max_load .TP .RE .PD .LP Attributes with a cumulative effect can be specified multiple times with the values specified each time accumulating (i.e. '=' does the same thing as '+='). With the exception of .I disabled they all have the same meaning as if they were specified in a service entry. .I disabled determines services that are disabled even if they have entries in the configuration file. This allows for quick reconfiguration by specifying disabled services with the .I disabled attribute instead of commenting them out. The value of this attribute is a list of space separated service ids. .I enabled has the same properties as disabled. The difference being that .I enabled is a list of which services are to be enabled. If .I enabled is specified, only the services specified are available. If .I enabled is not specified, all services are assumed to be enabled, except those listed in .I disabled. .\" *********************** INTERNAL SERVICES **************************** .SH "INTERNAL SERVICES" .LP \fBxinetd\fP provides the following services internally (both stream and datagram based): .I echo, .I time, .I daytime, .I chargen, and .I discard. These services are under the same access restrictions as all other services except for the ones that don't require \fBxinetd\fP to fork another process for them. Those ones (\fItime\fP, \fIdaytime\fP, and the datagram-based \fIecho\fP, \fIchargen\fP, and \fIdiscard\fP) have no limitation in the number of .B instances. .LP .\" *********************** TCPMUX Services **************************** .SH "TCPMUX Services" .LP \fBxinetd\fP supports TCPMUX services that conform to RFC 1078. These services may not have a well-known port associated with them, and can be accessed via the TCPMUX well-known port. .LP For each service that is to be accessed via TCPMUX, a service entry in \fB/etc/xinetd.conf\fP or in a configuration file in an \fBincludedir\fP directory must exist. .LP The \fIservice_name\fP field (as defined above for each service in any \fBxinetd\fP configuration file) must be identical to the string that is passed (according to RFC 1078 protocol) to \fBxinetd\fP when the remote service requestor first makes the connection on the TCPMUX well-known port. Private protocols should use a service name that has a high probability of being unique. One way is to prepend the service name with some form of organization ID. .LP The \fItype\fP field can be either \fBTCPMUX\fP or \fBTCPMUXPLUS\fP. If the type is \fBTCPMUXPLUS\fP, \fBxinetd\fP will handle the initial protocol handshake (as defined in RFC 1078) with the calling process before initiating the service. If the type is \fBTCPMUX\fP, the server that is started is responsible for performing the handshake. .LP The \fItype\fP field should also include \fBUNLISTED\fP if the service is not listed in a standard system file (like .I /etc/rpc for RPC services, or .I /etc/services for non-RPC services). .LP The \fIsocket_type\fP for these services must be \fBstream\fP, and the \fIprotocol\fP must be \fBtcp\fP. .LP Following is a sample TCPMUX service configuration: .PD .1v .RS .nf service myorg_server { .RS .IP disable 20 = no .IP type = TCPMUX .IP socket_type = stream .IP protocol = tcp .IP wait = no .IP user = root .IP server = /usr/etc/my_server_exec .RE } .fi .RE .PD .LP Besides a service entry for each service that can be accessed via the TCPMUX well-known port, a service entry for TCPMUX itself must also be included in the \fBxinetd\fP configuration. Consider the following sample: .PD .1v .RS .nf service tcpmux { .RS .IP type 20 = INTERNAL .IP id = tcpmux .IP socket_type = stream .IP protocol = tcp .IP user = root .IP wait = no .RE } .fi .RE .PD .\" *********************** NOTES **************************** .SH NOTES .IP 1. 4 The following service attributes \fIcannot\fP be changed on reconfiguration: .B socket_type, .B wait, .B protocol, .B type. .IP 2. When the attributes .I only_from and .I no_access are not specified for a service (either directly or via \fIdefaults\fP) the address check is considered successful (i.e. access will not be denied). .IP 3. The address check is based on the IP address of the remote host and not on its domain address. We do this so that we can avoid remote name lookups which may take a long time (since .B xinetd is single-threaded, a name lookup will prevent the daemon from accepting any other requests until the lookup is resolved). The down side of this scheme is that if the IP address of a remote host changes, then access to that host may be denied until .B xinetd is reconfigured. Whether access is actually denied or not will depend on whether the new host IP address is among those allowed access. For example, if the IP address of a host changes from 1.2.3.4 to 1.2.3.5 and only_from is specified as 1.2.3.0 then access will not be denied. .IP 4. If the .B USERID log option is specified and the remote host either does not run an identification server or the server sends back a bad reply, access will not be denied unless the .I IDONLY service flag is used. .IP 5. Interception works by forking a process which acts as a filter between the remote host(s) and the local server. This obviously has a performance impact so it is up to you to make the compromise between security and performance for each service. The following tables show the overhead of interception. The first table shows the time overhead-per-datagram for a UDP-based service using various datagram sizes. For TCP-based services we measured the bandwidth reduction because of interception while sending a certain amount of data from client to server (the time overhead should the same as for UDP-based services but it is "paid" only by the first packet of a continuous data transmission). The amount of data is given in the table as \fIsystem_calls\fPx\fIdata_sent_per_call\fP, i.e. each .I "send(2)" system call transferred so many bytes of data. The bandwidth reduction is given in terms of bytes per second and as a percentage of the bandwidth when interception is not performed. All measurements were done on a SparcStation IPC running SunOS 4.1. .sp 1 .RS .RS .PD .1v .TP 25 Datagram size (bytes) Latency (msec) .TP --------------------- -------------- .TP 64 1.19 .TP 256 1.51 .TP 1024 1.51 .TP 4096 3.58 .sp 2 .TP Bytes sent Bandwidth reduction .TP ---------- ------------------- .TP 10000x64 941 (1.2%) .TP 10000x256 4,231 (1.8%) .TP 10000x1024 319,300 (39.5%) .TP 10000x4096 824,461 (62.1%) .RE .RE .sp 1 .\" *********************** EXAMPLE **************************** .SH EXAMPLE .LP .PD .1v .RS .nf # # Sample configuration file for xinetd # defaults { .RS .IP log_type 20 = FILE /var/log/servicelog .IP log_on_success = PID .IP log_on_failure = HOST .IP only_from = 128.138.193.0 128.138.204.0 .IP only_from = 128.138.252.1 .IP instances = 10 .IP disabled = rstatd .RE } # # Note 1: the protocol attribute is not required # Note 2: the instances attribute overrides the default # service login { .RS .IP socket_type 20 = stream .IP protocol = tcp .IP wait = no .IP user = root .IP server = /usr/etc/in.rlogind .IP instances = UNLIMITED .RE } # # Note 1: the instances attribute overrides the default # Note 2: the log_on_success flags are augmented # service shell { .RS .IP socket_type 20 = stream .IP wait = no .IP user = root .IP instances = UNLIMITED .IP server = /usr/etc/in.rshd .IP log_on_success += HOST .RE } service ftp { .RS .IP socket_type 20 = stream .IP wait = no .IP nice = 10 .IP user = root .IP server = /usr/etc/in.ftpd .IP server_args = -l .IP instances = 4 .IP log_on_success += DURATION HOST USERID .IP access_times = 2:00-9:00 12:00-24:00 .RE } # Limit telnet sessions to 8 Mbytes of memory and a total # 20 CPU seconds for child processes. service telnet { .RS .IP socket_type 20 = stream .IP wait = no .IP nice = 10 .IP user = root .IP server = /usr/etc/in.telnetd .IP rlimit_as = 8M .IP rlimit_cpu = 20 .RE } # # This entry and the next one specify internal services.

Instead of having such servers started at system initialization time, and be dormant until a connection request arrives, \fBxinetd\fP is the only daemon process started and it listens on all service ports for the services listed in its configuration file. When a request comes in, \fBxinetd\fP starts the appropriate server. Because of the way it operates, \fBxinetd\fP (as well as \fBinetd\fP) is also referred to as a super-server. .LP The services listed in \fBxinetd\fP's configuration file can be separated into two groups. Services in the first group are called .I "multi-threaded" and they require the forking of a new server process for each new connection request. The new server then handles that connection. For such services, \fBxinetd\fP keeps listening for new requests so that it can spawn new servers. On the other hand, the second group includes services for which the service daemon is responsible for handling all new connection requests. Such services are called .I "single-threaded" and \fBxinetd\fP will stop handling new requests for them until the server dies. Services in this group are usually datagram-based. .LP So far, the only reason for the existence of a super-server was to conserve system resources by avoiding to fork a lot of processes which might be dormant for most of their lifetime. While fulfilling this function, \fBxinetd\fP takes advantage of the idea of a super-server to provide features such as access control and logging. Furthermore, \fBxinetd\fP is not limited to services listed in .I /etc/services. Therefore, anybody can use \fBxinetd\fP to start special-purpose servers. .\" *************************** OPTIONS ********************************* .SH OPTIONS .TP .BR \-d Enables debug mode. This produces a lot of debugging output, and it makes it possible to use a debugger on \fBxinetd\fP. .TP .BI \-syslog " syslog_facility" This option enables syslog logging of \fBxinetd\fP-produced messages using the specified syslog facility. The following facility names are supported: .I daemon, .I auth, .I user, .I "local[0-7]" (check \fIsyslog.conf(5)\fP for their meanings). This option is ineffective in debug mode since all relevant messages are sent to the terminal. .TP .BI \-filelog " logfile" \fBxinetd\fP-produced messages will be placed in the specified file. Messages are always appended to the file. If the file does not exist, it will be created. This option is ineffective in debug mode since all relevant messages are sent to the terminal. .TP .BI \-f " config_file" Determines the file that \fBxinetd\fP uses for configuration. The default is \fI/etc/xinetd.conf\fP. .TP .BR \-pidfile " pid_file" .br The process ID is written to the file. This option is ineffective in debug mode. .TP .BI \-dontfork Tells xinetd to stay in the foreground rather than detaching itself, to support being run from init or daemontools. This option automatically sets .B \-stayalive (see below). .TP .BI \-stayalive Tells xinetd to stay running even if no services are specified. .TP .BI \-limit " proc_limit" This option places a limit on the number of concurrently running processes that can be started by .B xinetd. Its purpose is to prevent process table overflows. .TP .BI \-logprocs " limit" This option places a limit on the number of concurrently running servers for remote userid acquisition. .TP .BI \-version This option causes xinetd to print out its version information. .TP .BI \-inetd_compat This option causes xinetd to read /etc/inetd.conf in addition to the standard xinetd config files. /etc/inetd.conf is read after the standard xinetd config files. .TP .BI \-cc " interval" This option instructs .B xinetd to perform periodic consistency checks on its internal state every .I interval seconds. .LP The \fIsyslog\fP and \fIfilelog\fP options are mutually exclusive. If none is specified, the default is syslog using the .I daemon facility. You should not confuse \fBxinetd\fP messages with messages related to service logging. The latter are logged only if this is specified via the configuration file. .\" *********************** CONTROLLING XINETD **************************** .SH "CONTROLLING XINETD" .LP \fBxinetd\fP performs certain actions when it receives certain signals. The actions associated with the specific signals can be redefined by editing \fIconfig.h\fP and recompiling. .TP 15 .B SIGHUP causes a hard reconfiguration, which means that \fBxinetd\fP re-reads the configuration file and terminates the servers for services that are no longer available. Access control is performed again on running servers by checking the remote location, access times and server instances. If the number of server instances is lowered, some arbitrarily picked servers will be killed to satisfy the limit; this will happen \fIafter\fP any servers are terminated because of failing the remote location or access time checks. Also, if the .B INTERCEPT flag was clear and is set, any running servers for that service will be terminated; \fIthe purpose of this is to ensure that after a hard reconfiguration there will be no running servers that can accept packets from addresses that do not meet the access control criteria\fP. .TP .B SIGQUIT causes program termination. .TP .B SIGTERM terminates all running servers before terminating \fBxinetd\fP. .TP .B SIGUSR1 causes an internal state dump (the default dump file is \fI/var/run/xinetd.dump\fP; to change the filename, edit \fIconfig.h\fP and recompile). .TP .B SIGIOT causes an internal consistency check to verify that the data structures used by the program have not been corrupted. When the check is completed .B xinetd will generate a message that says if the check was successful or not. .LP On reconfiguration the log files are closed and reopened. This allows removal of old log files. .\" *********************** FILES **************************** .SH FILES .LP .PD .1v .TP 20 .B /etc/xinetd.conf default configuration file .TP .B /var/run/xinetd.dump default dump file .PD .\" *********************** SEE ALSO **************************** .SH "SEE ALSO" .I "inetd(8)," .LP .I "xinetd.conf(5)," .LP .I "xinetd.log(5)" .LP .I "http://cr.yp.to/daemontools.html" .\" *********************** AUTHOR **************************** .SH AUTHOR Panos Tsirigotis, CS Dept, University of Colorado, Boulder Rob Braun .\" *********************** PRONUNCIATION **************************** .SH PRONUNCIATION zy-net-d xinetd-2.3.15/xinetd/main.c0000664000175000017500000001747310674505223015006 0ustar bbraunbbraun/* * (c) Copyright 1992 by Panagiotis Tsirigotis * (c) Copyright 1998-2001 by Rob Braun * All rights reserved.

When logging for a service is enabled, .B xinetd will generate one-line log entries which have the following format (all entries have a timestamp as a prefix): .sp 1 .RS \fIentry\fP: \fIservice-id\fP \fIdata\fP .RE .LP The \fIdata\fP depends on the \fIentry\fP. Possible \fIentry\fP types include: .RS .TP 12 .B START generated when a server is started .TP .B EXIT generated when a server exits .TP .B FAIL generated when it is not possible to start a server .TP .B USERID generated if the \fIUSERID\fP log option is used. .TP .B NOID generated if the .I USERID log option is used, and the .I IDONLY service flag is used, and the remote end does not identify who is trying to access the service. .RE .LP In the following, the information enclosed in brackets appears if the appropriate log option is used. .LP A \fISTART\fP entry has the format: .sp 1 .RS START: \fIservice-id\fP [pid=%d] [from=%d.%d.%d.%d] .RE .LP An \fIEXIT\fP entry has the format: .sp 1 .RS EXIT: \fIservice-id\fP [\fItype\fP=%d] [pid=%d] [duration=%d(sec)] .RE .sp 1 .I type can be either .B status or .B signal. The number is either the exit status or the signal that caused process termination. .LP A \fIFAIL\fP entry has the format: .sp 1 .RS FAIL: \fIservice-id\fP \fIreason\fP [from=%d.%d.%d.%d] .RE .sp 1 Possible \fIreasons\fP are: .RS .TP 15 .B fork a certain number of consecutive fork attempts failed (this number is a configurable parameter) .TP .B time the time check failed .TP .B address the address check failed .TP .B service_limit the allowed number of server instances for this service would be exceeded .TP .B process_limit a limit on the number of forked processes was specified and it would be exceeded .RE .LP A \fIDATA\fP entry has the format: .sp 1 .RS DATA: \fIservice-id\fP \fIdata\fP .RE .sp 1 The \fIdata\fP logged depends on the service. .RS .TP 12 .B login remote_user=%s local_user=%s tty=%s .TP .B exec remote_user=%s verify=\fIstatus\fP command=%s .br Possible .I status values: .RS .TP 10 .I ok the password was correct .TP .I failed the password was incorrect .TP .I baduser no such user .RE .TP .B shell remote_user=%s local_user=%s command=%s .TP .B finger \fIreceived string\fP or .I EMPTY-LINE .RE .LP A \fIUSERID\fP entry has the format: .sp 1 .RS USERID: \fIservice-id\fP \fItext\fP .RE .sp 1 The \fItext\fP is the response of the identification daemon at the remote end excluding the port numbers (which are included in the response). .LP A \fINOID\fP entry has the format: .sp 1 .RS NOID: \fIservice-id\fP \fIIP-address\fP \fIreason\fP .RE .\" *********************** SEE ALSO **************************** .SH "SEE ALSO" .BR xinetd "(1L), " xinetd.conf (5) xinetd-2.3.15/xinetd/int.h0000664000175000017500000000343507624737370014665 0ustar bbraunbbraun/* * (c) Copyright 1992 by Panagiotis Tsirigotis * (c) Sections Copyright 1998-2001 by Rob Braun * All rights reserved.

Original site: http://www.xinetd.org xinetd has access control mechanisms, extensive logging capabilities, the ability to make services available based on time, can place limits on the number of servers that can be started, and has deployable defence mechanisms to protect against port scanners, among other things. There are a number of differences between xinetd and inetd. The largest difference to the end user is the config file. xinetd's config file format is more C like, and somewhat similar to bind 8's. *** NOTE *** xinetd's reconfig signal is now SIGHUP. SIGUSR2 still works for now, but should be considered deprecated. The state dump signal is now SIGUSR1. *** *** There are a couple of compile time options to xinetd: -------------------------------------------------------------------------- --with-libwrap : This option to the configure script tells xinetd to compile in support for tcp wrappers. You must already have libwrap installed on your system. This option will have xinetd pay attention to your /etc/hosts.{allow|deny} files. With this option turned on, xinetd will first look at your /etc/hosts.{allow|deny} files, then if access is granted, it goes through xinetd's internal access control mechanisms. Note that xinetd passes the server name if there is one, otherwise it uses the service id, *not* the service name to libwrap - this is a change from previous behaviour. --with-loadavg : This option to the configure script tells xinetd to compile in support for the max_load configuration option. This option allows you to have certain services disabled when the system load gets above a specified level. This is highly operating system specific. It currently has been tested on linux, and there is developmental support for solaris 2.6 and higher. --with-inet6 : Services default to IPv6 (PF_INET6) sockets. Now that IPv6 support is fully integrated into xinetd, this option is almost meaningless. IPv6 sockets are available with the "IPv6" service flag, even without this option. --with-howl=PATH: Adds howl mdns advertising support to xinetd. PATH is the prefix where howl is installed, such as /usr/local, /usr, etc. PATH is not optional. configure will not automatically detect howl's installed location. Access Control: -------------------------------------------------------------------------- As of xinetd 2.1.8.8pre3 there is a change in the handling of names specified in the access control directives, only_from and no_access. For numerical entries in these fields, nothing has changed. The way it used to be: When xinetd started, it would lookup the name(s) specified. It would then collect all the IP addresses associated with that name, and store them in the access control lists. This led to problems of acls being out of date, and access controls being messed up when names were specified. It did have the advantage of not waiting for a lookup to happen when you connected. The way it is now: xinetd keeps all the names you specify on the access control directives. When a client attempts to connect to a service, a reverse lookup is performed on the client's IP address. The canonical name returned is compared with the specified names. If the first character of the name being specified in the config file is a '.', then all hosts within that domain are matched. For example, if I put .synack.net, all hosts with a reverse mapping that are in .synack.net domain, are matched. libwrap support: ---------------------------------------------------------------------- For libwrap access control, the access control is done by the server name for the service. So, if you have an entry like this: service telnet { ... server = /usr/sbin/in.telnetd ... } Your corresponding hosts.{allow|deny} entry would look something like this: in.telnetd: ALL However, many services don't have a "server". Internal services and redirection services don't have a "server" line in the configuration file. For these services, the service name is used. For example: server telnet { ... redirect = 10.0.0.1 23 ... } Your hosts.{allow|deny} entry would look something like this: telnet: ALL So, in general, if a service has a "server" attribute to it, access control is performed based on that entry. If a service does not have a "server" attribute, (internal and redirection services) then access control is based on the service name. This is only for libwrap access control. itox: -------------------------------------------------------------------------- I will continue to keep itox in the distribution, and fix any bugs or compatibility issues that come to my attention, but I probably won't get around to adding features. If someone else would like to pick this up, let me know and I'd be happy to incorporate changes. I have made a quick perl script (xconv.pl) to replace itox. xconv.pl does a straight translation of inetd.conf file syntax to xinetd.conf. It handles tcpd correctly, warns on the use of rpc services, sets the REUSE flag, and handles groups properly if your inetd.conf file supports them. xinetd was originally written by panos@cs.colorado.edu. At least one other version of xinetd has been seen floating around the net. This version is being maintained by Rob Braun (bbraun@synack.net) and bug reports for this version should be directed there. Known bugs: On some BSD's, you may need to set 'groups = yes' in your services. If you need this, and you don't specify 'groups = yes', you'll get a log message telling you it is needed, when you connect to a service. Bug reports/comments/suggestions/flames for this version should be sent to bbraun@synack.net xinetd-2.3.15/libs/0000775000175000017500000000000011752512710013335 5ustar bbraunbbraunxinetd-2.3.15/libs/src/0000775000175000017500000000000011752512710014124 5ustar bbraunbbraunxinetd-2.3.15/libs/src/sio/0000775000175000017500000000000011752512710014716 5ustar bbraunbbraunxinetd-2.3.15/libs/src/sio/siosup.c0000664000175000017500000005506410674523600016420 0ustar bbraunbbraun/* * (c) Copyright 1992, 1993 by Panagiotis Tsirigotis * All rights reserved.

The first argument of every function or macro is a file descriptor. The file descriptor may be used either for input or for output but not both. Attempting to use a descriptor for both input and output will cause the call to fail. When you are done with using a file descriptor, you should inform \fISIO\fR by invoking \fBSdone()\fR (unless the program is about to call \fIexit(3)\fR). You can also use \fBSdone()\fR if you want to perform a different type of operation on the same file descriptor (e.g. first you were reading data from the file descriptor and then you want to write some data). Another possibility is to do stream I/O at different file offsets by using \fBSdone()\fR before doing the \fBlseek(2)\fR to the new file offset. .LP I/O operations on different file descriptors do not interfere (unless the file descriptors refer to the same file, in which case the results are undefined). .LP For disk files I/O always starts at the current file offset. If that offset is not a multiple of the preferred block size for file system I/O (the \fIst_blksize\fR field in \fIstruct stat\fR), performance will not be optimal. For optimal performance, it is recommended that no I/O operations (like \fIread(2)\fR or \fIwrite(2)\fR) are applied to the file descriptor if it is to be used by \fISIO\fR. .LP Read I/O is either buffered or is done using memory mapping whenever that is possible and appropriate. .LP The library functions that do stream I/O resemble system calls (for example \fBSread()\fR resembles \fIread(2)\fR) so that modifying a program that uses the system calls to use the \fISIO\fR functions is easy (e.g. just replace \fIread(2)\fR with \fBSread()\fR; the function signatures as well as the return values are exactly the same). .LP .B Sread() reads \fInbytes\fR bytes from the stream associated with file descriptor \fIfd\fR into the buffer pointed to by \fIbuf\fR. .LP .B Sgetc() reads a character from the stream associated with file descriptor \fIfd\fR. It returns \fBSIO_EOF\fR if the end of file has been reached. .LP .B Sgetchar() (a macro) performs exactly the same function as \fBSgetc()\fR but it is much faster. .LP .B Srdline() reads a line from the stream associated with file descriptor \fIfd\fR. The newline at the end of the line is replaced by a 0 byte. Lines longer than the maximum line length supported by \fISIO\fR will have characters deleted. .LP .B SIOLINELEN() (a macro) returns the length of the line returned by the last call to \fBSrdline()\fR (the value returned by \fBSIOLINELEN()\fR is valid only after \fBSrdline()\fR and as long as no other \fISIO\fR calls are performed on that file descriptor). .LP .B Sfetch() returns a pointer to data coming from the stream associated with file descriptor \fIfd\fR. The amount of data available is indicated by the \fIlength\fR argument. One possible use for this function is copying of files. .LP .B Swrite() writes \fInbytes\fR bytes to the stream associated with file descriptor \fIfd\fR from the buffer pointed to by \fIbuf\fR. .LP .B Sputc() writes a single character to the stream associated with file descriptor \fIfd\fR. .LP .B Sputchar() (a macro) performs exactly the same function as \fBSputc()\fR but it is much faster. .LP .B Sprint() imitates the behavior of printf(3) as defined in the ANSI C Standard. There are some limitations. Check the \fBSprint()\fR man page for more information. .LP .B Sprintv() is the same as \fBSprint()\fR except that it takes a \fIstdarg\fR argument list. .LP .B Sundo() returns the characters returned by the last call to \fBSrdline()\fR, \fBSgetc()\fR or \fBSgetchar()\fR to the stream so that they can be reread. The \fItype\fR argument to \fBSundo()\fR can be \fBSIO_UNDO_LINE\fR or \fBSIO_UNDO_CHAR\fR depending on whether the call whose effect needs to be undone was \fBSrdline()\fR or \fBSgetc()\fR/\fBSgetchar()\fR respectively. There is no check on whether the last function invoked on \fIfd\fR was one of the above and the results are undefined if there is no correspondence between the \fItype\fR and the last operation on \fIfd\fR. (i.e. the result is undefined if you try \fBSIO_UNDO_CHAR\fR and the last operation was not \fBSgetchar()\fR or \fBSgetc()\fR). .LP .B Stie() ties the file descriptor \fIifd\fR to the file descriptor \fIofd\fR. This means that whenever a \fIread(2)\fR is done on \fIifd\fR, it is preceded by a \fIwrite(2)\fR on \fIofd\fR. For filters it is useful to do \fIStie( 0, 1 )\fR to maximize concurrency. It is also useful to do the same thing when you issue prompts to the user and you want the user reply to appear on the same line with the prompt. \fIifd\fR, \fIofd\fR will be initialized for input, output respectively (if any of them is initialized, it must be for the appropriate stream type (input or output)). If \fIifd\fR was tied to another file descriptor, the old tie is broken. .LP .B Suntie() undoes the effect of \fBStie()\fR for the specified input file descriptor. .LP .B Sbuftype() determines the buffering type for the output stream associated with file descriptor \fIfd\fR. By default output directed to terminals is line buffered, output directed to file descriptor 2 (standard error) is unbuffered and everything else is fully buffered. Possible values for the \fItype\fR argument are .RS .TP 15 .B SIO_FULLBUF for full buffering .TP .B SIO_LINEBUF for line buffering .TP .B SIO_NOBUF for no buffering .RE .LP .B Smorefds() should be used to inform \fBSIO\fR that the number of available file descriptors has been increased. \fBSIO\fR uses an array of internal stream descriptors which are indexed by the file descriptor number. Some operating systems (ex. SunOS 4.1[.x]) allow the number of available file descriptors to vary. If that number is increased beyond its initial value \fBSIO\fR needs to know in order to allocate more stream descriptors. .LP .B Sdone() flushes any buffered output for \fIfd\fR and releases the \fISIO\fR resources used. \fBSdone()\fR is useful in case the program needs to reprocess the data of a file descriptor (assuming the file descriptor corresponds to a file). The program can call \fBSdone()\fR, \fIlseek(2)\fR to the beginning of the file and then proceed to reread the file. .LP .B Sflush() causes any buffered stream output to be written to the file descriptor. If its argument is the special value \fBSIO_FLUSH_ALL\fR then all output streams will be flushed. .LP .B Sclose() closes a file descriptor used for stream I/O, flushes any buffered output and releases the \fISIO\fR resources used. .SH EXAMPLES .LP The following code implements a (poor) substitute for the tee command (it copies standard input to a file as well as to standard output). .ne 10 .RS .nf .ft B #include "sio.h" .sp .5 main( argc, argv ) int argc ; char *argv[] ; { char *file = (argc > 1) ? argv[ 1 ] : "tee.file" ; int fd = creat( file, 0644 ) ; long length ; char *s ; .sp .5 while ( s = Sfetch( 0, &length ) ) { Swrite( 1, s, length ) ; Swrite( fd, s, length ) ; } exit( 0 ) ; } .fi .ft R .RE .SH RETURN VALUES .LP .B Sread() returns the number of bytes read on success (0 means end-of-file) or \fBSIO_ERR\fR on failure (\fIerrno\fR is set to indicate the error). .LP .B Sgetc() returns the character read on success, SIO_EOF when the end-of-file is reached, or \fBSIO_ERR\fR on failure (\fIerrno\fR is set to indicate the error). .LP .B Srdline() returns a pointer to the next line on success. On failure or when the end-of-file is reached it returns .SM NULL. If the end-of-file is reached \fIerrno\fR is set to 0, otherwise it indicates the error. .LP .B Sfetch() returns a pointer to file data on success. (the \fIlength\fR argument indicates how many bytes are available). On failure or when the end-of-file is reached it returns .SM NULL. If the end-of-file is reached \fIerrno\fR is set to 0, otherwise it indicates the error. .LP .B Swrite() returns the number of bytes written on success or \fBSIO_ERR\fR on failure (\fIerrno\fR is set to indicate the error). .LP .B Sputc() returns the character it was given as an argument on success .B Sprint() returns the number of characters printed on success or \fBSIO_ERR\fR on failure (\fIerrno\fR is set to indicate the error). .LP .B Sdone() returns \fB0\fR on success or \fBSIO_ERR\fR on failure (\fIerrno\fR is set to indicate the error). .LP .B Sundo() returns \fB0\fR on success or \fBSIO_ERR\fR on failure (\fIerrno\fR is set to indicate the error). .LP .B Stie() returns \fB0\fR on success or \fBSIO_ERR\fR on failure (\fIerrno\fR is set to indicate the error). .LP .B Suntie() returns \fB0\fR on success or \fBSIO_ERR\fR on failure (\fIerrno\fR is set to \fBEBADF\fR if there was no tied file descriptor). .LP .B Sbuftype() returns \fB0\fR on success or \fBSIO_ERR\fR on failure (\fIerrno\fR is set to \fBEBADF\fR if this is not an output stream or to \fBEINVAL\fR if an unknown \fItype\fR is specified). .LP .B Smorefds() returns \fB0\fR on success or \fBSIO_ERR\fR on failure (because of lack of memory). .LP .B Sflush() returns \fB0\fR on success or \fBSIO_ERR\fR on failure (\fIerrno\fR is set to indicate the error). .LP .B Sclose() returns \fB0\fR on success or \fBSIO_ERR\fR on failure (\fIerrno\fR is set to indicate the error). .LP .B Sgetchar() returns the character read on success, SIO_EOF when the end-of-file is reached, or \fBSIO_ERR\fR on failure (\fIerrno\fR is set to indicate the error). .LP .B Sputchar() returns the character it was given as an argument on success or \fBSIO_ERR\fR on failure (\fIerrno\fR is set to indicate the error). .LP .B SIOLINELEN() returns the length of the last line read by \fBSrdline()\fR. .LP Attempting a read operation on a descriptor opened for writing or vice versa will cause the operation to fail with \fIerrno\fR set to \fBEBADF\fR. .LP The first \fISIO\fR operation on a descriptor must be a read or write operation. It cannot be a control operation (like \fBSflush()\fR). Such an operation will fail with \fIerrno\fR set to \fBEBADF\fR. .LP .IP "\fBNOTE 1:\fR" 15 \fBStie()\fR is an input/output operation for the respective file descriptors, not a control operation. \fBSuntie()\fR is a control operation. .IP "\fBNOTE 2:\fR" \fBSIO_ERR\fR is defined to be \fB-1\fR. .SH "SEE ALSO" .LP Sprint(3) .SH BUGS .LP If the operating system does not provide for invocation of a finalization function upon exit, the program will have to explicitly flush all output streams. The following operating systems provide such a facility: SunOS 4.x, Ultrix 4.x. .LP Socket file descriptors can be used for input as well as output but \fBSIO\fR does not support this. .LP The current implementation will not try to use memory mapping to read a file if the file offset is not 0 (it will use buffered I/O instead). .LP Pointers returned by \fBSfetch()\fR point to read-only memory. Attempting to modify this memory will result in a segmentation violation. xinetd-2.3.15/libs/src/sio/sio.h0000664000175000017500000001105310674523600015663 0ustar bbraunbbraun/* * (c) Copyright 1992, 1993 by Panagiotis Tsirigotis * All rights reserved.

Using the same tabstop value will make the text/code look properly indented. ====================================================================== 1. What is SIO ? SIO is a library that provides _stream_ I/O which is what most Unix programs do. As such it is a competitor to stdio. 2. Why would you care to use it ? a. SIO is a little faster than stdio b. SIO provides an easier-to-use interface (IMHO) c. SIO is capable of using memory mapping for reading files if the operating system supports it. d. If you have a program that uses read(2)/write(2) it is trivial to convert it to use SIO (just replace read with Sread and write with Swrite) e. You get source 3. Setting up the Stream I/O (SIO) library There are 3 steps to the process: 1) modifying the SIO configuration file (but you can skip this step if you are using one of the operating systems listed below). 2) testing SIO 3) installing the library and manpages 3.1. How to compile the Stream I/O (SIO) library All the system-dependent stuff of SIO is placed in the sioconf.h file. If your system is not listed below, you will need to read that file to see what flags you need to set to properly compile SIO. For the following systems, here is what you need to do: SunOS 4.x: make "DEFS=-DHAVE_MMAP -DHAVE_ONEXIT -DHAVE_MEMCPY -DHAVE_ISATTY" SunOS 5.x (aka Solaris 2.y): make "DEFS=-DHAVE_MMAP -DHAVE_ATEXIT -DHAVE_MEMCPY -DHAVE_ISATTY" (I don't have access to a system running Solaris 2.y so I have not tested this) Ultrix 4.x: make "DEFS=-DHAVE_MEMCPY -DHAVE_ATEXIT -DHAVE_ISATTY" If your system is one of the above, then you can skip to the next subsection. However, I should mention that the library compiles by default with debugging enabled (i.e. uses the -g flag of cc). You can override this by appending to the invocation of 'make' the argument "DEBUG=-O" If your system is not among the above, then you will need to modify the sioconf.h file. You do this by uncommenting the inclusion of customconf.h. Then, you can override all constants/macros defined in sioconf.h by defining them first in customconf.h. Please read sioconf.h for more information on what constants/macros can be defined. The Makefile has a header that explains what the Makefile can do. The only flag that you may want to define is -DDEBUG which enables assertions in the SIO code (if an assertion fails, the program is terminated with an error message that lists the SIO file and line number where the error occured). 3.2. Testing SIO After you have successfully compiled SIO, you can use the programs in the "suite" directory to test the SIO functions. Testing should be done before installing the library. The script testlib does everything; just type: testlib all The script sprint_test (invoked by testlib) tests Sprint by using a variety of formats and comparing its output with that of an ANSI-compatible printf. At least on Ultrix 4.1 and 4.2 this test fails because printf is not ANSI-compatible. In such a case, you can test the rest of the SIO functions by typing: testlib all Sprint (anything after the 'all' argument is interpreted as a function that should not be tested). The README file in the "suite" directory describes how to do a few more tests that cannot be done automatically. 3.3. Installing the library and manpages The 'make' command will create libsio.a in the current directory. The Makefile includes an "install" target. Doing a 'make install' will cause the following: a) libsio.a will be installed in LIBDIR b) the necessary SIO header files will be installed in INCLUDEDIR c) the SIO man pages will be installed in MANDIR LIBDIR, INCLUDEDIR, and MANDIR are Makefile variables that you can edit in the Makefile or override when you invoke 'make'. Here is a sample command to install SIO: make install LIBDIR=/usr/local/lib INCLUDEDIR=/usr/local/include MANDIR=/usr/local/man/man3 4. Epilogue Feel free to modify SIO to suit your needs.

The formatting is controlled by the \fIformat\fR argument. All characters in \fIformat\fR that do not specify a conversion are printed. A conversion is specified by a '%' followed by a string that ends with a conversion type character. The string may contain flags, a field width, a precision, and a modifier. .LP Possible flags (more that one can be specified and they can be in any order) include: .TP 10 .B \'-' specifies left adjustment of the converted argument. The default is right adjustment. This flag is meaningful only if a field width is specified. .TP .B \'+' specifies that a number will always have a sign as a prefix (this forces a '+' sign to appear if the number is positive). .TP .B \' ' prefixes a \fIspace\fR to the number if the number has not a sign (therefore the '+' flag overrides this flag). .TP .B \'#' The meaning of '#' depends on the conversion type character: for \fBo\fR conversions the first digit will be 0; for \fBx\fR or \fBX\fR conversions \fB0x\fR or \fB0X\fR respectively will be prefixed to the number (if it is not zero); for \fBe\fR, \fBE\fR, \fBf\fR, \fBg\fR, and \fBG\fR conversions the number will always have a decimal point. .TP .B \'0' specifies padding with zeros instead of spaces. .LP The field width is specified by a number. This number indicates the \fIminimum\fR width for the field. A '*' may be used instead of the number. In that case the width is the value of the next argument which should be an \fBint\fR. A negative width value specifies left adjustment with a width equal to the absolute width value. .LP A precision is specified by a '.' followed by a number. The meaning of the precision depends on the type conversion character. For a string conversion, precision determines how many characters are printed from the string. For integer conversions, precision determines the number of digits used to print the number (zero padding is done if the precision exceeds the length of the number). For floating point conversions, precision determines the number of digits after the decimal point (\fBe\fR, \fBE\fR, \fBf\fR) or the number of significant digits (\fBg\fR, \fBG\fR). A '*' may be used instead of a number to specify the precision. In that case the precision is the value of the next argument which should be an \fBint\fR. The behavior of \fBSprint()\fR is undefined if the precision is negative. .LP The length modifier is \fBl\fR and indicates that the argument is a \fBlong\fR integer. .LP The type conversion characters are: \fBd, i, o, x, X, u, c, s, f, e, E, g, G, p, n, %\fR. For floating point conversions the argument should be of type \fIdouble\fR. .TP 10 .B d,i specify signed decimal conversion. .TP .B u specifies unsigned decimal conversion. .TP .B o specifies octal conversion. .TP .B x,X specify hexadecimal conversion. For .B x the hex digits used are 0123456789abcdef. For .B X the hex digits used are 0123456789ABCDEF. There is no leading .B 0x or .B 0X (use the '#' flag for that). .TP .B c specifies character conversion; the argument should be of type \fIchar\fR. .TP .B s specifies string conversion; the argument should be of type \fIchar *\fR. .TP .B f specifies conversion to the form [-]ddd.dddd. The number of digits after the decimal point depends on precision; the default is 6. If the precision is 0, the decimal point is not printed (this can be overriden with the '#' flag). .B e,E specify conversion to the form [-]ddd.dddd[eE][+-]ddd. The number of digits after the decimal point depends on precision; the default is 6. If the precision is 0, the decimal point is not printed (this can be overriden with the '#' flag). The exponent is at least 2 digit wide. .TP .B g,G specify a conversion using the .B e,E format respectively if the exponent is less than -4 or greater than or equal to the precision; otherwise the .B f format is used. .TP .B p is used to print pointers (type \fIvoid *\fR, or \fIchar *\fR if the compiler does not support the former). .TP .B n expects a \fIint *\fR argument and puts in that integer the number of characters already printed by this call. .TP .B % is used to print a \fI%\fR. .LP If an unknown conversion character is specified, the percent sign followed by that character will be printed. .SH RETURN VALUE .LP If no error occured, \fBSprint()\fR returns the number of characters printed. In case of error, it returns \fBSIO_ERR\fR. .SH BUGS .LP This is a list of differences between \fBSprint()\fR and the ANSI C Standard \fBprintf()\fR: .LP \fBSprint()\fR does not support non-removal of trailing zeroes for \fBg\fR and \fBG\fR conversions when the '#' flag is used. .LP \fBSprint()\fR does not support the h and L modifiers. .LP The current implementation assumes that \fIsizeof(int)==sizeof(long)\fR. .LP \fBSprint()\fR supports "%p" only if \fIsizeof(pointer)<=sizeof(int)\fR. xinetd-2.3.15/libs/src/sio/install-sh0000775000175000017500000001272107624737367016751 0ustar bbraunbbraun#! /bin/sh # # install - install a program, script, or datafile # This comes from X11R5 (mit/util/scripts/install.sh). # # Copyright 1991 by the Massachusetts Institute of Technology # # Permission to use, copy, modify, distribute, and sell this software and its # documentation for any purpose is hereby granted without fee, provided that # the above copyright notice appear in all copies and that both that # copyright notice and this permission notice appear in supporting # documentation, and that the name of M.I.T. not be used in advertising or # publicity pertaining to distribution of the software without specific, # written prior permission.

Pointers can be inserted and deleted from sets and the sets can be enumerated. Pointers are inserted in sets in no particular order. However it is guaranteed that a sequence of insertions will result in a set which if enumerated will provide the pointers in the same order in which they were inserted (assuming no intervening deletions). .LP .B pset_create() creates a pointer set. .I alloc_start determines the initial table size, and .I alloc_step determines the amount by which the set size is increased in case of overflow. If any of these parameters is 0, a default value is used. .LP .B pset_destroy() destroys the specified pointer set. .LP .B pset_add() is a macro that adds a pointer to the specified set. The pointer can be of any type. .LP .B pset_insert() inserts a pointer to the specified set. This is the same operation as .B pset_add(). .LP .B pset_remove() removes a pointer from the specified set. .LP .B pset_delete() deletes a pointer from the specified set. This is the same operation as .B pset_remove(). .LP .B pset_remove_index() removes the pointer that is at position .I index in the set. .I index should be in the range [0, \fBpset_count(pset)\fP) (but there is no check to enforce this). After this operation, the .I index position will be occupied by another pointer. .LP .B pset_clear() removes all pointers from the specified set. .LP .B pset_count() returns the number of pointers in the specified set. .LP .B pset_pointer() returns the pointer at position .I index in the specified set. .I index must be between 0 and .B "pset_count(pset)." .B pset_pointer() is a macro and it can also be used in the left-hand side of assignments. .LP .B pset_compact() removes all NULL pointers from .I pset. .LP .B pset_sort() sorts the pointers in .I pset using the specified function. .I compfunc is invoked with 2 arguments that are pointers pointing to pointers stored in .I pset. For example, if the pset holds pointers to objects of type T, then the function F whose address is in .I compfunc should be defined as: F( T **p1, T **p2 ). .br .I compfunc should return a negative, zero or positive value if its first argument is less than, equal to, or greater than its second argument. .LP .B pset_apply() applies .I func to all pointers in .I pset. If .I arg is not .SM NULL the function is invoked as: .RS (*func)( arg, p ) .RE where .I p is a pset pointer. If .I arg is .SM NULL the function is invoked as: .RS (*func)( p ) .RE .SH EXAMPLE The following code fragment reads lines from standard input and places them in a pset. Then it sorts the pset, prints the sorted contents to standard output and then it eliminates duplicate lines (which it also prints to standard output). .RS .sp 1 .ft B .nf pset_h ph ; char buf[ 80 ] ; unsigned u ; int compstr() ; void printstr() ; .sp 1 ph = pset_create( 0, 0 ) ; while ( gets( buf ) ) .RS pset_add( strcpy( malloc( strlen( buf ) + 1 ), buf ) ) ; .RE pset_sort( ph, compstr ) ; for ( u = 0 ; u < pset_count( ph ) ; u++ ) .RS printf( "%s\\n", (char *) pset_pointer( ph, u ) ) ; .RE .RE .fi .ft R .LP The function .I compstr() follows: .sp 1 .RS .ft B .nf int compstr( p1, p2 ) .RS char **p1, **p2 ; .RE { .RS return( strcmp( *p1, *p2 ) ) ; .RE } .RE .SH "RETURN VALUES" .LP .I pset_h is a pointer type. Functions that return .I pset_h will return .SM NULL to indicate an error. .LP .B pset_create() returns a pointer set handle or .SM NULL if it fails. .LP .B pset_add() returns its second argument if successful or .SM NULL if it fails. .LP .B pset_insert() returns its second argument if successful or .SM NULL if it fails. .LP .B pset_count() always returns the number of pointers in the set. .LP .B pset_pointer() always returns a pointer. There is no check if the specified index is within range. .SH BUGS .LP .B pset_add(), .B pset_remove(), .B pset_remove_index(), .B pset_count(), .B pset_clear(), .B pset_pointer() and .B pset_sort() are macros, therefore the \fI&\fR operator cannot be applied to them. xinetd-2.3.15/libs/src/pset/pset.h0000664000175000017500000000467307632712614016244 0ustar bbraunbbraun/* * (c) Copyright 1992, 1993 by Panagiotis Tsirigotis * All rights reserved.

The only operation that should be applied to an iterator after it is created is .B psi_start(). .LP .B psi_destroy() destroys the iterator. .LP .B psi_reset() changes the pset that is being iterated to .I pset. .LP .B psi_start() starts an iteration and returns the first pointer in the pointer set. .LP .B psi_next() returns the next pointer in the set. .LP .B psi_remove() removes the current pointer from the set. The current pointer is the one returned most recently from either .B psi_start() or .B psi_next(). .SH "RETURN VALUES" .LP .B psi_create() returns an iterator handle on success or .SM NULL on failure. .LP .B psi_start() returns the first pointer from the set or .SM NULL if the set is empty. .LP .B psi_next() returns a pointer or .SM NULL if the end of the set is reached. .SH WARNINGS .B psi_create() is the only function in this library. The rest of the interface is macros. .LP This interface may be eliminated in a future release of the .I pset library. xinetd-2.3.15/libs/src/pset/COPYRIGHT0000664000175000017500000000247607624737367016427 0ustar bbraunbbraunThis software is (c) Copyright 1992, 1993 by Panagiotis Tsirigotis The author (Panagiotis Tsirigotis) grants permission to use, copy, and distribute this software and its documentation for any purpose and without fee, provided that the above copyright notice extant in files in this distribution is not removed from files included in any redistribution and that this copyright notice is also included in any redistribution.

Strings that are .SM NULL pointers are ignored. \fBmake_string()\fR returns malloc'ed memory. .LP .B make_pathname() creates a pathname by catenating the list of pathname components passed as arguments and inserting slashes between them. \fIcount\fR indicates how many components there are. \fBmake_pathname()\fR returns malloc'ed memory. .LP .B argv_copy_and_clear() creates a new argv array of size \fIcount\fR, and fills it with the contents of \fIargv\fR from \fIstart\fR up to \fIstart+count-1\fR. The original \fIargv\fR entries in that range are cleared by filling them with .SM SPACEs. .LP .B dirname() returns in a malloced string containing all but the last of component of \fIpath\fR. There are 2 special cases: first when the \fIpath\fR is "/", \fBdirname()\fR will return "/", and second, when the \fIpath\fR does not contain any '/', \fBdirname()\fR will return ".". .LP .B basename() returns a pointer to the last component of \fIpath\fR. .SH "RETURN VALUES" .LP \fBmake_string()\fR returns a pointer to the new string. It returns .SM NULL if \fIcount\fR is 0. .LP \fBmake_pathname()\fR returns a pointer to the new pathname. It returns .SM NULL if \fIcount\fR is 0. .LP \fBargv_copy_and_clear()\fR returns the new argv array. It returns .SM NULL if \fImalloc\fR fails to allocate more memory. .LP \fBdirname()\fR returns a new string or .SM NULL if \fImalloc\fR fails to allocate more memory. .LP \fBbasename()\fR returns a pointer to the last component of \fIpath\fR. .SH BUGS .LP The behavior of \fBdirname()\fR and \fBbasename()\fR is undefined if they are given a zero-length string. xinetd-2.3.15/libs/src/misc/m_env.c0000664000175000017500000001136507666404447016355 0ustar bbraunbbraun/* * (c) Copyright 1992 by Panagiotis Tsirigotis * All rights reserved.

An environment is a set of strings of the form .I "name=value". In the following, we will use the term string as a synonym of NUL-terminated array of .I char. .LP .B env_create() creates a new environment. The new environment will be empty unless the argument .I env is not .SB ENV_NULL. In that case, the new environment will be a duplicate of .I env (i.e. they will contain the same strings). .LP .B env_destroy() destroys the specified environment. .LP .B env_make() creates a new environment which includes the .I env_strings. .I env_strings should be a NULL-terminated array of strings. .LP .B env_addvar() adds the specified variable .I var to .I env. The variable value is obtained from the environment .I from_env. If the variable exists already in .I env the old value is replaced with the new value. .LP .B env_addstr() adds a string of the form .I "name=value" to .I env. .LP .B env_remvar() removes the specified variable .I var from the environment .I env. .LP .B env_lookup() searches .I env for variable .I var. It returns a string of the form .I "name=value" where .I name is the name of the variable (i.e. it is equal to .I var). .LP .B env_getvars returns a NULL-terminated array of strings of the form .I "name=value". .SH "RETURN VALUES" In case of error, all calls will place an error code in the global variable .I env_errno. Possible error codes: .TP 15 .SB ENV_ENOMEM out of memory .TP .SB ENV_EBADVAR variable is not in environment .TP .SB ENV_EBADSTRING string is not well-formed (i.e. is not of the form \fIname=value\fR). .LP .B env_create() returns a handle or .SM ENV_NULL if it fails. .LP .B env_make() returns a handle or .SM ENV_NULL if it fails. .LP .B env_addvar() returns .SM ENV_OK on success or .SM ENV_ERR on failure. .LP .B env_addstr() returns .SM ENV_OK on success or .SM ENV_ERR on failure. .LP .B env_remvar() returns .SM ENV_OK on success or .SM ENV_ERR if the variable is not part of the environment. .LP .B env_loopkup() returns a string on success or .SM NULL on failure. .SH "SEE ALSO" environ(5) xinetd-2.3.15/libs/src/misc/misc.c0000664000175000017500000000106207624737367016201 0ustar bbraunbbraun/* * (c) Copyright 1992 by Panagiotis Tsirigotis * (c) Portions Copyright 1998-2001 by Rob Braun * All rights reserved.

Currently, the only logging facilities supported are .I "syslog(3)" and logging to files. Log entries are timestamped lines which may contain arbitrary information. .\" ********************* xlog_create *********************** .LP .B xlog_create() creates a new xlog of the specified .I type. Possible type values are: .RS .TP 20 .SB XLOG_SYSLOG Varargs: \fIint facility, int priority\fP. The xlog will be connected to .I "syslog(3)." .I facility determines the syslog facility to use for logged messages and .I priority is the default message priority. .TP .SB XLOG_FILELOG Varargs: \fIchar *pathname, int flags [, int flags]\fP. The xlog will be connected to the file identified by .I pathname. The variable part of the argument list has the same semantics as the argument list of the .I "open(2)" system call. .RE .LP All xlogs have an id, specified by the .I id argument. The .I flags argument is formed by ORing one or more of the following constants: .RS .TP 20 .SB XLOG_NO_ERRNO do not replace .I "%m" with an explanation of the current value of errno. .TP .SB XLOG_NO_SIZECHECK .I "(XLOG_FILELOG only)" do not perform size checks on the file. .TP .SB XLOG_PRINT_ID precede each log entry with the xlog id .TP .SB XLOG_PRINT_PID precede each log entry with the process id (the process id will follow the xlog id) .RE .LP Flags that do not apply to the xlog are ignored. The contant .SM XLOG_NOFLAGS can be used if you don't want to specify any flags. .\" ********************* xlog_parms *********************** .LP .B xlog_parms() sets default parameters for the specified xlog .I type: .RS .TP 20 .SB XLOG_SYSLOG 3 arguments are expected which correspond one-to-one to the arguments of .I "openlog(3)." The defaults, in case this function is not used, are: "XLOG", LOG_PID + LOG_NOWAIT, LOG_USER .TP .SB XLOG_FILELOG No action. .RE .LP .B xlog_parms() should be invoked before any xlogs of the specified type are created. .\" ********************* xlog_destroy *********************** .LP .B xlog_destroy() destroys an xlog. The action taken depends on the type of the xlog: .RS .TP 20 .SB XLOG_SYSLOG if this is the last xlog using syslog, then .I "closelog(3)" is invoked. .TP .SB XLOG_FILELOG The file is closed. .RE .\" ********************* xlog_control *********************** .LP .B xlog_control() applies control operations to an xlog. Certain operations are common to all xlogs while others are type-specific. The common ones are: .RS .TP 15 .SB XLOG_LINK Argument list: \fIxlog_h link_to\fP. Link the specified xlog to the one provided as argument. (if the argument is .SM NULL any existent link is severed). Linking xlogs has the effect that if one finds an error it uses the other to report it. .TP .SB XLOG_CALLBACK Argument list: \fIvoid (*callback)(), void *arg\fP. This function will be invoked in case of error while writing a log entry. It will be given 3 arguments: the xlog handle, an integer that indicates the type of error and the .I arg specified in this call. Possible errors include: .RS .TP 15 .SB XLOG_ENOMEM lack of memory .TP .SB XLOG_EOPEN .I "open(2)" failed .TP .SB XLOG_EFSTAT .I "fstat(2)" failed .TP .SB XLOG_ESIZE hard limit exceeded .RE .TP .SB XLOG_SETFLAG Argument list: \fIint flag, int *value\fP. The value of .I flag (one of those listed before) is set according to .I "*value" which should be either 0 or 1. The old flag value is placed in .I "*value." .TP .SB XLOG_GETFLAG Argument list: \fIint flag, int *value\fP. The value of .I flag (one of those listed before) is placed in .I "*value." .RE .LP Xlogs of type .B XLOG_SYSLOG also support the following operations: .RS .TP 15 .SB XLOG_FACILITY Argument list: \fIint facility\fP. Sets the syslog facility to the specified value. .TP .SB XLOG_LEVEL Argument list: \fIint level\fP. Sets the default syslog level for this xlog to the specified value. .TP .SB XLOG_PREEXEC Argument list: \fIvoid\fP. Prepares the xlog for an impending exec operation .TP .SB XLOG_POSTEXEC Argument list: \fIvoid\fP. Informs the xlog that the exec failed .RE .LP Xlogs of type .B XLOG_FILELOG also support the following operations: .RS .TP 15 .SB XLOG_LIMITS Argument list: \fIunsigned soft_limit, unsigned hard_limit\fP. Sets soft and hard limits on the size of the file. When any of the limits is exceeded a message is sent to the linked xlog. (if there is no linked xlog, no message is sent) When the soft limit is exceeded a warning message is sent to the linked xlog (if the linked xlog is of the .SB XLOG_SYSLOG type, the message will be sent at the .I LOG_ALERT level). If the exceeded limit is the hard limit, logging is terminated. The actual file size is checked every time this operation is applied to the file. If logging was terminated because the hard limit was exceeded and this operation increases the hard limit beyond the actual file size, logging will be resumed. .TP .SB XLOG_SIZECHECK Argument list: \fIvoid\fP. Checks the actual file size. .TP .SB XLOG_GETFD Argument list: \fIint *value\fP. Places in .I "*value" the file descriptor of the log file. .RE .\" ********************* xlog_write *********************** .LP .B xlog_write() writes a message to the specified xlog. A .SM NEWLINE is always appended to the message. The first occurrence of "%m" in .I buf is replaced by a string explaining the current value of .I errno. The .I flags argument is formed in the same way as in .B xlog_create(). One additional constant is available: .RS .TP 20 .SB XLOG_SET_LEVEL .I "(XLOG_SYSLOG only)" the next argument is an integer that should be used as the syslog level for this message instead of the default level of the xlog. .RE .SH "RETURN VALUES" .B xlog_create() returns an xlog handle or .SM NULL if it fails. .LP .B xlog_control() returns an error code (it returns .SM XLOG_ENOERROR if it is successful). .LP .B xlog_parms() returns an error code (it returns .SM XLOG_ENOERROR if it is successful). .SH "SEE ALSO" openlog(3), syslog(3), closelog(3) .SH BUGS .LP Only the first occurrence of .I "%m" is replaced by an errno explanation. .LP There is no check for cycles when linking xlogs. In particular it is possible to link a xlog to itself. xinetd-2.3.15/libs/src/xlog/COPYRIGHT0000664000175000017500000000247607624737367016425 0ustar bbraunbbraunThis software is (c) Copyright 1992, 1993 by Panagiotis Tsirigotis The author (Panagiotis Tsirigotis) grants permission to use, copy, and distribute this software and its documentation for any purpose and without fee, provided that the above copyright notice extant in files in this distribution is not removed from files included in any redistribution and that this copyright notice is also included in any redistribution.

Using the same tabstop value will make the text/code look properly indented. ====================================================================== 1. What is this library about ? The STR library consists of string handling functions. These functions can be separated into 4 groups: A. String matching functions. A variety of algorithms are available for string matching: brute force Rabin-Karp Knuth-Morris-Pratt Boyer-Moore Shift-or B. String printing functions (similar to sprintf). These functions offer 2 significant advantages over sprintf: 1) they include functions that will *not* overrun the string buffer provided 2) they include functions returning "char *" as well as functions returning "int" so that one can pick the most appropriate one. C. String parsing functions. These functions offer an easy way of breaking a string into pieces. D. String utility functions. This group includes functions that will convert a string to upper/lower case etc. 2. Setting up the STR library All you need to do is type 'make'. This will create the library in the current directory. The string printing functions use (and therefore require) the underlying format conversion facility of my SIO (Stream I/O) library. If you don't want to bother with it, you can define the flag NO_SIO in the Makefile (check the Makefile comments on how to do this) which will turn all string printing functions to no-ops. The SIO library is available from mystique.cs.colorado.edu in the directory pub/libs (it may also be available at other places). Make sure you get SIO version 1.6.2 or later; versions prior to 1.6.2 will result in identical behavior between the strx_*print* and the str_*print* functions.

Their only difference is in their return values. For information about their conversion capabilities, check \fISprint(3)\fR. .LP The difference between the \fIstr_*\fR and the \fIstrx_*\fR functions is that the latter take an extra argument, the size of the buffer, so that they will never write beyond the end of the buffer. Writing beyond the end of the buffer is possible with the \fIstr_*\fR functions. Previously, invoking any of the \fIstrx_*\fR functions with the .I len argument set to 0 used to be the same as calling the equivalent \fIstr_*\fR function. This dangerous behavior has since been changed and now the \fIstrx_*\fR functions don't touch the buffer when .I len is 0 or negative. .LP All functions will append a .SM NUL at the end of .I buf (the \fIstrx_*\fR functions will not do this if it would cause a buffer overrun). .LP .B str_print(), .B str_printv(), .B strx_print(), and .B strx_printv() will put in .I "*countp" the number of characters placed in .I buf excluding the ending .SM NUL (this happens only if .I "*countp" is not .SM NULL ). .LP The functions that have a name ending in 'v' are similar to those without the 'v' at the end of their name except that instead of accepting a variable number of arguments, they expect a \fIstdarg(3)\fR argument list. .SH "RETURN VALUES" .LP .B str_sprint(), .B str_sprintv(), .B strx_sprint(), and .B strx_sprintv() return .I buf. .LP .B str_nprint(), .B str_nprintv(), .B strx_nprint(), and .B strx_nprintv() return the number of characters placed in .I buf excluding the ending .SM NUL. .SH "SEE ALSO" Sprint(3) xinetd-2.3.15/libs/src/str/CHANGELOG0000664000175000017500000000066507624737367016201 0ustar bbraunbbraun 1.2.0: First release (as part of xinetd 1.3) 1.3.2: Added the string matching functions 1.3.3: (posted to alt.sources) Changed the way the library is configured 1.4.0: Added the shift-or string matching algorithm Implemented the automatic switching to the proper search algorithm Added the STRS_NOSWITCH flag to disallow switching Added the STRS_PATLEN flag 1.4.1: Moved definition of u_wide_int from ss_rk.h to ss_impl.h xinetd-2.3.15/libs/src/str/install-sh0000775000175000017500000001272107624737367016767 0ustar bbraunbbraun#! /bin/sh # # install - install a program, script, or datafile # This comes from X11R5 (mit/util/scripts/install.sh). # # Copyright 1991 by the Massachusetts Institute of Technology # # Permission to use, copy, modify, distribute, and sell this software and its # documentation for any purpose is hereby granted without fee, provided that # the above copyright notice appear in all copies and that both that # copyright notice and this permission notice appear in supporting # documentation, and that the name of M.I.T. not be used in advertising or # publicity pertaining to distribution of the software without specific, # written prior permission.

In this context parsing means breaking the string into substrings. The substrings are separated by a list of possible separator characters. .LP .B str_component() returns successive substrings of the string. .B str_parse() creates and initializes a string parser with the string that will be processed, \fIstr\fR, the list of possible separator characters, \fIsepar\fR, and flags that control how the parser works. The \fIflags\fR argument is formed by ORing one or more of the following constants: .TP 20 .SB STR_RETURN_ERROR If something goes wrong return a value that indicates that an error occured (e.g. out of memory). The default is for the program to be terminated with an appropriate error message. .TP .SB STR_NULL_START If \fIstr\fR starts with a separator then a zero-length string will be returned the first time \fBstr_component()\fR is called. .TP .SB STR_NULL_END If \fIstr\fR ends with a separator then a zero-length string will be returned by \fBstr_component()\fR when the substrings of \fIstr\fR are exhausted. .TP .SB STR_MALLOC The strings returned by \fBstr_component()\fR will be in malloc'ed memory. By default the substrings are part of \fIstr\fR. If this option is not used \fIstr\fR will be modified by \fBstr_component()\fR. .LP Finally, \fBSTR_NOFLAGS\fR may be used to specify no flags. The \fIerrnop\fR argument points to an integer where the string processing functions will deposit an error code if an error occurs. If \fIerrnop\fR is .SM NULL the error codes will be placed in \fIstr_errno\fR. This is useful only if \fBSTR_RETURN_ERROR\fR is used in \fIflags\fR. It is possible that \fIstr\fP is .SM NULL. In this case, a subsequent .B str_setstr() should be used to specify the string to be processed. .LP .B str_component() returns successive substrings from the string associated with the parser specified by \fIhandle\fR. .LP .B str_endparse() destroys the parser specified by \fIhandle\fR. .LP .B str_setstr() changes the processed string to \fInewstr\fP. .LP .B str_separator() replaces the list of separator characters with \fIsepar\fR. Processing continues from the current position. .LP .B str_nextpos() returns a pointer to the rest of the string. The previous character is a separator character (if \fBSTR_MALLOC\fR is not set, then the previous character is .SM NUL ). .SH "RETURN VALUES" .LP .B str_parse() returns a parser handle or .SM NULL if something goes wrong and \fIflags\fR & \fBSTR_RETURN_ERROR\fR is true. Possible \fIstr_errno\fR values: .RS .TP 20 .SB STR_ENULLSEPAR \fIsepar\fR is .SM NULL .TP .SB STR_ENOMEM the program ran out of memory .RE .LP .B str_component() returns a pointer to the next substring or .SM NULL if something goes wrong and \fIflags\fR & \fBSTR_RETURN_ERROR\fR is true. .LP .B str_setstr() returns .SB STR_OK on success or .SB STR_ERR on failure. .LP .B str_separator() returns .SB STR_OK on success or .SB STR_ERR on failure. .LP .B str_nextpos() returns a pointer or .SM NULL if the end of string has been reached. .SH BUGS .B str_component() modifies the string unless \fBSTR_MALLOC\fR is set in the parser. .LP There should be only one parser active on a specific string. If there is more than one, they all must use the \fBSTR_MALLOC\fR option. xinetd-2.3.15/libs/src/str/strparse.c0000664000175000017500000001020410674523600016742 0ustar bbraunbbraun/* * (c) Copyright 1992, 1993 by Panagiotis Tsirigotis * All rights reserved.

The audit has been performed in order to make the Owl (http://www.openwall.com/Owl/) xinetd package reasonably secure and of course with the hope that others will find the results and patches useful as well. Much of xinetd's logic is left unaudited (other than for generic bug classes listed below). In particular, this applies to all network access control checks. To summarize the results, xinetd may be reasonably safe to use with these patches, but the code remains far from clean and certain bugs are there by design. The format of this list is one item per line, with subitems indented. If a line doesn't start with a '+', that item hasn't been completed (audited and/or patched). None of the PATCH'es are a part of xinetd-2.3.0; they will be in the Owl package and hopefully will get incorporated into future versions of xinetd. -- Solar Designer +BUGS strx_* functions (danger:

xinetd-2.3.15/CHANGELOG0000664000175000017500000012542711752512505013633 0ustar bbraunbbraun This file describes the changes to xinetd. The base version is 2.0.0. 2.0.0: (not released) 2.0.1: (not released) 2.0.2: Changes to the Makefile. Trivial mods to the usage() function 2.0.3: Changes to the Makefile. Fixed a bug in the usage() function 2.0.4: Distribution versions of the Makefile no longer contain any references to options.opt 2.0.5: 1) Clarified what an "unlisted RPC service" is in the man page 2) Fixed a bug in remote_address_check which caused access to be denied for all hosts if no_access was set and only_from was not set. 3) Fixed a bug which caused arbitrary syslog levels if the log_type was specified as SYSLOG in the "defaults" entry 2.0.6: bug fix in child.c: replaced strx_sprint with strx_print when naming interceptor processes ------------------------------------------------------------------------------- 2.1.0: (not released) This was mostly a clean-up of 2.0 List of changes: A. The man page has been split into 3 parts: xinetd.man : man page describing the program xinetd.conf.man : man page describing the configuration file This file now includes figures about the overhead of interception. xinetd.log.man : man page describing the log file B. New service attributes rpc_number : to support unlisted RPC services nice : to set the nice value of forked servers C. The IDONLY service flag was added D. Now uses the timer library unless NO_TIMERS is defined. If NO_TIMERS is not defined, the following are also available: a) a new option, -cc, to do periodic consistency checks b) timeout for reconfiguration E. Configuration file man page now mentions that access control is based on IP-address instead of domain address. F. The interception code now sets the TCP_NODELAY option. G. The timeout when contacting a remote identification server is configurable both when the service request has been accepted and when the request is rejected. In the former case it defaults to infinity while in the latter it defaults to 30 sec. H. The log line ids are now constants in an include file. I. The fsma library is no longer used. J. Most structure fields were renamed; certain functions were renamed too. Access to structure fields is now via macros. K. A bug in not restoring the number of descriptors to the soft limit was fixed. L. The -pid option works M. New internal services: "servers" : lists active servers "services" : lists active services 2.1.1: xinetd produces more meaningful messages if it can't start logging 2.1.2: Fixed 2 bugs: 1) xinetd would request a port number for unlisted RPC services One could get around this by simply specifying the port attribute for the service; the specified value would be ignored anyway. 2) xinetd initialization might fail sometimes in function msg_init() syslog logging was specified (i.e. the option -syslog was used) The cause of this bug was that the xlog_control( xlog, XLOG_GETFD, &fd ) operation will not fail for xlogs connected to syslog and the value of 'fd' would be used in the subsequent fcntl(). That value is arbitrary since 'fd' is a local variable. If 'fd' did not happen to refer to an open descriptor, the program would terminate since the fcntl() would fail (btw, the success of the fcntl() call would be harmless if 'fd' happened to refer to an open descriptor). 2.1.3: Bug fix: only_from/no_access addresses would get inverted on little-endian machines when such addresses were specified using the numeric notation (for example, 128.138.45.3). This bug was in the numeric_addr function which did not convert the result of inet_addr to host-byte-order. A work around for the bug would be to use the factorized address notation (for example, 128.138.45.{3}) 2.1.4: Bug fixes: 1) in dgram_echo(), sin_len was not being set before the invocation of recvfrom 2) in finger_shutdown(), it was possible for Srdline() to return NULL (if the remote end would close the socket without sending anything). If the RECORD option was set in the log_on_failure flags, this would cause the forked xinetd process which did the recording to die since it would try to dereference a NULL pointer. 2.1.5: Bug fixes: 1) in exec_server() service descriptor might be closed when execing server. This made it impossible to start servers for 'nowait' services. The bug occurred only Ultrix version 4.3a or (probably) later (bug discovered and fix provided by doug@seas.smu.edu) 2) for systems that supported supplementary group id's, the set_credentials() function did not set those group id's (they were being inherited from xinetd). Now initgroups(3) is called to set the supplementary group id's properly. (bug discovered and fix provided by maf+@osu.edu) 2.1.6: Bug fixes: 1) xinetd will crash after reconfiguration if there is a running server for a service that was removed from the configuration and which logs on exit. 2) xinetd forked process falls in infinite loop if identd server sends a reply that is missing the ending CR-LF. (bug discovered and fix provided by Laurent.Wacrenier@gin.obspm.fr). We also change the LOGUSER_SUCCESS_TIMEOUT constant in config.h from 0 seconds (i.e. infinite timeout) to 30 seconds. This avoids infinite waits in case the remote host does not send a RST reply when we attempt to connect to the IDENTD port, and there is no server listening at that port. 2.1.7: Bug fix: the HOST flag in the 'log_on_success' attribute was ignored; the code was incorrectly checking if the HOST flag was set in the log_on_failure attribute (bug discovered by frolich@corrine.cpc.cs.ucf.edu) 2.1.8.1: Added support for TCP redirect to a remote host. --bbraun 2.1.8.2: Added support for binding to specific interface. --bbraun 2.1.8.3: Changed redirect so that a remote port can be specified as well. --bbraun 2.1.8.4 10/98: Changed use of varargs to be more modern (and actually work on IRIX 6.5) Added use of 1.2.3.4/24 style address ranges for access control --bbraun 2.1.8.4p2 11/98: Fixed stupid error with logging of ip addresses. Pointed out by Todd R. Eigenschink 2.1.8.4p3 11/98: Fixed to compile correctly under HPUX Includes fixes from Pavel Roskin 2.1.8.4p4 11/98: Fixed to compile correctly under BSDi 2.1.8.4p5 11/98: Fixed Linux libc5 to work with RPC. Pointed out by Frodo Looijaard 2.1.8.4p8 11/98: Minor jump because I went through many revisions of testing things - Fixed littleendian bug with 1.2.3.4/26 style access control - Added support for inet_addr instead of inet_aton, as Solaris 2.5.1 does not support inet_aton. Both the previous bugs were found with the help of Thomas E. (tht@inlink.com) - Went entirely to stdarg.h version of variable arguement handling, since some newer platforms doen't handle varargs.h style very gracefully. If this breaks too many older architectures I'll ifdef all the old stuff back in... 2.1.8.5 11/98: Fixed /tmp/xinetd.dump symlink problem pointed out on BugTraq by Balazs Nagy 2.1.8.5p1 1/99: Fixed compilation problems on BSD systems. 2.1.8.5p2 1/99: Fixed compilation problems on AIX 4.1.x/powerpc 2.1.8.5p3 3/99: Fixed compilation problems on FreeBSD Thanks to Sascha Schumann Fixed a bug in sio/sprint.c Thanks to Steven Stanfield 2.1.8.6b1 4/99: Rudimentary administrative interface added (use the service name xadmin). Supports the "banner" directive, which is the name of the file that will be splatted when a connection is denied. Has a fixed open() on the dump file that is much better. Thanks to Steven Stanfield $REMOTE_HOST environment variable is set to the name of the remote host. Currently, if no name is available, it is set to NULL. 2.1.8.6b2 4/99: Fixed a problem with shells that don't define $PWD 2.1.8.6b3 4/99: Fixed a problem I introduced with automagic port selection If both a port and a protocol are specified, no checks are done. xinetd will believe the config, even if /etc/services says otherwise. xadmin service is an internal service now, just like tcp echo, etc. Use the INTERNAL flag. xadmin service now just calls server_dump when a "show run" command is executed. Added a NAMEINARGS flag, so that you can use tcpd with xinetd. Normally, xinetd takes argv[0] from the "server" directive. This prevents tcpd from working properly. Now, you can use tcp wrappers like this: service telnet { scoket_type = stream protocol = tcp flags = NAMEINARGS wait = no user = root server = /usr/libexec/tcpd server_args = /usr/libexec/telnetd } 2.1.86b4 4/99: Added support for libwrap. Compile with --with-libwrap. Access checking is done with libwrap (if compiled in) first, then with xinetd's internal access control. 2.1.8.6b5 4/99: Some versions of libwrap needed allow_severity. Added it. Changed severity to INFO from WARNING. 2.1.8.6b6 7/99: Added ability to use names for the bind and redirect functions. They lookup the name, and use the first address it returns. They only do the lookup once. Added "interface" as an alias to "bind" Fixed potential bug with redirection losing data. Pointed out by Solar Designer Fixed potential bug in the parsing of xadmin commands. Pointed out by Solar Designer Changed default location of the dump file to /var/run/xinetd.dump configurable in config.h Added Solar Designer's per_source feature. Allows you to limit the number of services spawned per source address. Added Solar Designer's supplementary groups fix. 2.1.8.6b7 7/99: Updated the make files to not require absolute paths. This will help with people having problems with the LOCATION Makefile variable. Updated configure to compile properly with Debian's version of libwrap and glibc (look for yp_get_default_domain in nsl) If banner directive is used, banner is printed regardless of access control. It is actually printed before access control check take place. banner_success and banner_fail are added to explicitly give a message depending on access control. Added banner_success option. This is a banner that is printed when access to the service is granted. This is before any attempt to execute the server has been made. The service may still fail but it will not be for access control reasons. Added banner_fail option. This is a banner that is printed when access to the service has been denied. This allows you to inform your users that they are doing something bad and they shouldn't be doing it anymore. Added max_load option. This option allows the operator to specify the max load at which to run the service. If the machine reaches the specified max load level, connections are denied to that service. Each service can have a different max_load, and it can be listed in the default service. Linux is working, Solaris is kind of wierd. Solaris people should try it, but don't use it as a real security mechanism yet. 2.6 and 2.7 should be fine. I'm not sure about 2.5.1 and earlier. 2.1.8.7 10/99: Fixed per_source to actually work properly. Added the NODELAY flag. This will set the TCP_NODELAY sockopt on the socket. If the service is not a TCP service, then this flag has no effect. Updated the man page with more explicit definition of the "groups" attribute. Includes xconv.pl to replace itox. xconv.pl handles most of the inetd.conf files I've seen, including the use of tcpd, even though it is recommended that you compile with libwrap instead of using tcpd. Includes a man page to itox donated by Norbert Veber of Debian. Updates to configure and Makefile to better handle the configuration of install directories. Again, changes donated by Debian group. Updates to itox to handle user.group syntax and checking on "wait". 2.1.8.8pre1 11/99 Fixed a problem with the banner_fail parser. Added IPv6 support to xinetd. 2.1.8.8pre2 12/99 Added the option "cps". This allows you to disable a service if the rate of incoming connections is too great. This number may be set higher than the instances or per_source number. This is used as a last ditch measure, if someone is bombarding a service, and either 1) logs are piling up because of failed attempts, or 2) way too much is happening, ditch the service. This actually does a close() on the socket, so nothing is listening to that port anymore. All connections will fail. 2.1.8.8pre3 12/99 Made the options mask_t an unsigned long long (64bits on x86) instead of an unsigned. xinetd was running out of bits to store options in. Eventually, a real solution will need to be implemented, but this works for the short term. This may break on compilers that don't understand long long's. Be aware. Most modern compilers are ok. Added the option "enabled", similar to the "disabled" function. If "enabled" is used, only the services listed in the enabled line are available, regardless of what other services are configured. Changed the behavior of only_from and no_access. First, if you specify a host by _name_ in only_from or no_access, a lookup happens when a client connects. The _canonical_ name that is returned is compared to the name specified in the access control option. If the _names_ match, access is granted or denied. See the readme for more information. Added the ability to specify .domain.com to the access control options. This is very similar to tcp wrapper's method of specifying domain access. If the connecting client's reverse lookup returns a name that ends in .domain.com then access is granted or denied. See the readme for more information. 2.1.8.8pre4 12/99 The enable function didn't work. It worked for one entry, but more than 1 entry would not be recognized and xinetd would exit with no services available. I believe this has been fixed. limits.h is included in parsers.c now, because of LONG_MIN and LONG_MAX. Some setups would automagically include limits.h through the other include files, and some wouldn't. This should fix compile problems on those that don't. Added a check for sys_siglist in the configuration script. This is better than statically defining #ifdef's in signals.c. 2.1.8.8pre5 12/99 Fixed numeric addresses being entered in the only_from field. host_addr parser was identifying them and marking them as HOST_ADDRs instead of NUMERIC_ADDRS. 2.1.8.8pre6 1/100 Fixed year formatting in log to print 00 instead of 100. 2.1.8.8pre7 1/00 Fixed the TIMEOFFSET macro in builtins.c so the 'time' service printed the correct output. 2.1.8.8pre8 1/00 Fixed a problem where banners would not work saying "could not find banner: bannername". 2.1.8.8pre9 1/00 The dump file was logging the ip address incorrectly for only_from addresses. For some reason xntoa() was reporting the wrong address. Changed to inet_ntoa, and works fine. BSDI 4.1 was not compiling correctly, "inet_ntoa" not found. This is because BSDI4.x switched to using bind 8 resolver libraries, so you have to include to #define all these functions to __func_name. Some BSD's don't let you set the group permissions of a process to NULL, so you get the setgroups(0,NULL) error whenever a connection is made. To avoid this, set 'groups = yes' and be aware of the extra group permissions the server may be running with. A message to this effect has been added to the syslog error, so confusion is minimized. 2.1.8.8pre10 2/00 Fixed a syntax error when compiling IPv6 support. 2.1.8.8pre11 2/00 Always call no_control_tty(). This calls setsid() and fixes a problem under FreeBSD. 2.1.8.8 2/00 Bumped version number. 2.1.8.9pre1 Added the "include" directive. You can now include other files into your .conf file. "include filename" Added preliminary an inetd compatibility mode. Start xinetd with -inetd-compat and specify /etc/inetd.conf as your configuration file. 2.1.8.9pre2 Fixed up RPC support 2.1.8.9pre3 Incorporated patches for Mac OS X and Tru64 support. Also incorporated a patch for the includedir directive. 2.1.8.9pre4 Incorporated a patch to allow logging to the AUTHPRIV level. patch from Trond Eivind Glomsr. Numerous cleanups. Mostly superficial, but gets rid of *lots* of compile warnings when using -Wall. These cleanups may have affected portability issues... Support for Darwin! Now compiles and runs fine. Note that xinetd doing mmap didn't work right (always lost the first byte of the file). Workaround is to disable mmapped io for Darwin. Added a DISABLE flag for services, that will prevent a service from starting. Added a "disable" boolean for services that does the same thing as the DISABLE flag. "groups" can now be specified in the defaults section. 2.1.8.9pre5 Implemented better error checking in redirect.c, so hopefully it will detect error conditions more reliably and prevent lots of child xinetd's running unecisarily. Ramon Krikken sent a redirector implementation that replaced the two process redirection with a single process using select. Modifications to his patch were integrated. includedir parses only regular files, or symlinks to regular files, that do not begin with '.'. Added includedir to the xinetd.conf man page. 2.1.8.9pre6 Fixed a bug in the access lists. If you specified a host by name in only_from, any connection from a host without a reverse dns entry would be accepted. 2.1.8.9pre8 Now allows you to specify multiple instances of the same service as long as all but one is disabled. Fixed a documentation issue in the xinetd.conf man page. The user attribute can be specified for an unlisted service, just not an internal service. When including files with "includedir", it parses the files in alphabetical order, as determined by strcmp(). Under Solaris, I've removed the no_control_tty() call in child.c. This was causing some confusion. xinetd its self still calls no_control_tty(). Fixed a compile error with --with-inet6 Changed the exiting behavior: xinetd now kills only the RPC services and internal services (like redir) when it exits (or does a hard reconfigure). This keeps things like telnet sessions open across restarts of xinetd (assuming you are using REUSE). 2.1.8.9pre9 Fixed a potential bug in parsing of filenames from includedir. Possibly fixed tcp wait=yes handling. Fixed man pages so they say they're installed in the sections they are really installed into. Added .cvsignore to empty directories 2.1.8.9pre10 Hopefully fixed a few compile errors on architectures such as DUNIX and Darwin. When compiled with libwrap support, xinetd passes the server name to be checked in hosts.{allow,deny} instead of the service name. Behavior should now match tcpd. Incorporated Trond's pidfile patch. You can now specify -pidfile on the command line, and xinetd will make a /var/run/xinetd.pid file. Note that this _replaces_ the -pid option. 2.1.8.9pre11 Removed '\n's from syslog messages. Also moved some of the syslog()'s to pasemsg()'s. Added a patch from mob@de.uu.net to make the bind attribute specifiable in the default section. Added the KEEPALIVE flag, which sets the SO_KEEPALIVE socketopt on tcp sockets. Added a patch from Trond at RedHat that will hopefully fix some of the remaining tcp wait=yes problems. More paranoid handling of access control in addr.c Always allow access to the internal pseudo services. For internal services and libwrap, access control is performed by the service name (instead of the server, since there is no server). The last two entries together fix problems with segfaults when doing access control. If a hostname is specified in only_from, xinetd will try to match the connecting address to any of the IP addresses associated with the hostname in only_from. For redirection services with libwrap support, the service name is used for access control rather than the server name, since the server name makes no sense. 2.1.8.9pre12 Remove the pidfile when exiting. Added a -stayalive option to keep xinetd running even when there are no services available. 2.1.8.9pre13 Added paranoid access control for the udp internal servers. Do not reply to udp packets on dangerous ports (avoid looping echo services). For libwrap, if the server isn't specified use the service _id_ instead of the service name (this usually is the service name). This makes more sense for things like the internal servers (echo-stream instead of using echo, which will get echo-stream and echo-dgram) Included an rlimit patch from Nick Burrett, which should help keep some nasty users at bay. He's even updated the man page. This patch brings a tear to my eye. 2.1.8.9pre14 Moved the libwrap and address checking to the child process. The purpose of this is to move the expensive checking into the child process (such as name resolution, exec()'ing, etc), but leave some of the lighter weigh checking in the parent in an attempt to prevent DoS'. Incorporated Charles Levert's NOLIBWRAP patch. This adds a flag, NOLIBWRAP, which will turn off libwrap access control for a single service. This is a good thing when you're wanting to use tcpd with a service. It's also useful when wanting libwrap for some lesser used services, but the high volume ones need higher performance. Included Motonobu Ichimura's patches for v6. The first one sets v6 services with incoming v4mapped or compatible addresses to AF_INET instead of AF_INET6. This should make incoming v4 connections to v4 servers work correctly. Motonobu Ichimura's second patch adds the service attribute v6config, which allows a v6 service to only accept v6 connections. Moved most of the configured defines into a config.h. This involved renaming xinetd/config.h to xinetd/xconfig.h The configure system actually works with --srcdir now. You can build xinetd from a directory other than the source directory now. Minor cleanups to remove warnings with -Wall 2.1.8.9pre15 5/20/2001 Added Steve Grubb's SENSOR patch which provides a SENSOR flag and deny_time attribute. These will help to stop script kiddies doing port scans by turning off all access to all services on all IP addresses until the timeout expires. Cleaned up pset stuff in the lib section. Continued fixing warnings produced by -Wall Added "child" security check for internal services. Fixed some possible memory leaks. Changed snprintf to the internal strx_nprint() function, standardizing on that. Removed the need for the snprintf() implementation for systems lacking snprintf(). Another attempt to fix the tcp wait condition. TCP wait services were being accept()'d when they shouldn't This caused services such as linuxconf, which accept() their own connections, to fail. Fixed a problem with displaying bound and redirected addresses in the xadmin service. Don't print banner always and banner success twice. Converted to ANSI C style prototypes instead of K&R. Use spaces instead of 3 character tabs. Use POSIX types for network, time, and other length specific purposes. Make the initial log message of compile time options atomic. When grow()'ing the environment variables, initialize things to prevent bad pointers. Mitigated consequences of possible SIGCHLD race with intercepted services. Removed all remnants of varargs syntax, and have completely moved to the stdarg style syntax. Added BSD/OS loadavg support from Robert Brewer at LavaNet. Fixed a potential buffer overflow when using USERID. Found by zen-parse. Added permissions to the pidfile's open call. Suggested by zen-parse. Changed xinetd's umask to 022 from 0. 2.1.8.9pre16 6/13/2001 Attempted to fix IPv6 support broken in the pre15 release. -Steve Grubb Moved remote_address_check ahead of the libwrap checks. This is needed so that SENSORS work without modifying the hosts.allow file if tcp_wrappers is compiled in. -Steve Grubb Added missing includes to several library files Fixed bug where DISABLE flag was being set/cleared in xflags rather than types. -Matthias Andree Fixed memory leak in attr_check. -Steve Grubb Continued converting to ANSI C prototypes. -Steve Grubb Fixed reads in service.c to continue through interupts. -Steve Grubb Corrected Includedir directive. -Solar Designer Changed umask to OR 022 with the current umask. -Solar Designer Cleaned up the address list dump to format the different addresses types correctly. -Steve Grubb Cleaned up parsing of address lists. -Steve Grubb Integrated support for building on OS X. Added wait/nowait support to "small services". Fixed IPv6 support for "small services". Added "umask" keyword to specify service's umask in octal. Umask situation is described in the umask section of xinetd.conf.man Inspect all configuration files. Will now emit warnings if any are world writeable, symlinks, or not owned by root.-Steve Grubb 2.3.0 Fixed a bounds checking case in strx* functions. Pointed out by Sebastian Krahmer. 2.3.1 Reworked all headers in xinetd directory. -Steve Grubb Fixed redirect & shutdown to read & write through signal interrupts. -Steve Grubb Inspect all servers. Prints warnings for things that look funny. Applied _many_ security and reliability fixes, see AUDIT. -Solar Designer Removed the Soft Reconfigure capability. Soft Reconfigure is now the same as Hard Reconfigure (SIGUSR1 = SIGUSR2). -Steve Grubb Attempt to fix segfaulting seen since 2.3.0. -Steve Grubb Moved the re-enable service after cps violation to run off of the flags system to avoid re-entrancy issues. -Steve Grubb Only call drain if service is active. Deactivated services close the descriptor. -Steve Grubb Reorganized flags to process terminating children first, -Steve Grubb 2.3.2 more K&R -> ANSI prototype -Steve Grubb Stop using C++ keywords (even though this is really C...) -Steve Grubb Fix a heap overrun in grow(). -teg@redhat.com Fix a parse error with multiple explict masks. If protocol is not specified, but socket type is, infer protocol from socket type. -Ahmon Dancy Added a check to the return value of env_addstr() in child.c to make sure we aren't exec()ing with an invalid environment. Wrap the remaining includes with autoconf macros. Removed all unused functions. -Steve Grubb Don't use SIGALRM for the cps directive. Instead, do a generic timer routine that evolves around the main event loop. 2.3.3 Fixed the filelog problem of printing garbage. Fixed the RPC parser to correctly handle RPC version ranges again. 2.3.4 Removed the old flags construct and replaced it with the timers added in 2.3.2. This will handle multiple of the same signals occuring before the event loop cycles. Removed all the old timer code that uses SIGALRM, and replace it with the timer code from 2.3.2. The conf timer bit the dust along the way, since the event loop hasn't started by the time the conf parser started. It was never built anyway, so not a big loss. Made xinetd unlink its pidfile properly. - Solar Designer Enabled loadavg support for Darwin. Remove the exit when user or group is specified and xinetd is not root. Enables running xinetd as non-root again. Fixed various portability issues: - strerror for SunOS 4 - difftime for SunOS 4 - inet_aton for Solaris 2.5.1 - uint{16,32,64}_t for systems without them - rlim_t for systems without them. Moved compat.c into the portable library, where it belonged. Added finer testing of the {e,f,g}cvt functions in autoconf. Begin transition to combined IPv4/IPv6 support. Add compatibility code from OpenSSH into the portable library. Made socket_type or protocol optional (only need to specify one) Removed syslog()'s, replaced with internal msg(). Fixed a parsing bug when specified server is invalid. Change the signal handling. Signal handlers write their signal to a pipe, which wakes up the main select(), and the signal is then dealt with. Removed the looping option. The cps directive duplicated much of the functionality. Fixed a bug re-enabling internal wait services. Continue syncing IPv4 and IPv6 code. Made a flag to specify IPv4 or IPv6 based service. Redirect currently only redirects between IPv4<->IPv4 or IPv6<->IPv6. It should handle IPv4<->IPv6 and vice versa Fixed the reconfig case where a bind directive changes. SIGHUP now reconfigures xinetd. SIGUSR1 now dumps the internal state. SIGUSR2 still reconfigures xinetd, but will be deprecated in future releases. Fixed a warning of redefined SA macro with some tcp wrapper header files. Make the configuration keyword comparisons case insensitive. This allows things like Service foo { blah } instead of just service foo { blah }. Merged IPv4 and IPv6 support. The only difference between compiling with IPv6 support is that services default to being IPv6. Manually set the service to IPv6 (or IPv4) with the IPv{4,6} service flags. The only_from numeric address specification works for IPv6 addresses, and mixing IPv4 style address specifications will now match for IPv4 mapped addresses on IPv6 services. Fixed an environment variable setting problem. Fixed a misuse of the sio routines in the banner routines. This will probably fix a variety of bugs related to banners. More code cleanups. -Steve Grubb. Pass the expected size of the address structure used to bind() calls rather than the total memory allocated. Fix some compile errors and warnings on BSD/OS. Prevent some possible unnecissary DNS lookups. Makefiles now accept make -j. This is only mildly useful at the moment, since the main chunk of xinetd blocks on all the libraries being built first, and the libraries are small but somewhat serialized. Fixed a problem with the access control on builtin services. (Introduced in the development cycle) Removed libpq. It is no longer needed. -Steve Grubb Removed the %n processing from __sio_converter(). It is not used and would cause a core dump if it was. -Steve Grubb Make the man page match the new signal change. - Steve Grubb Fix some potential problems with only_from access. Start using "const". Go const happy. All services now essentially default to having the REUSE flag. The -reuse option and the REUSE flag are now silently ignored. When dumping service configs, print out the redir config information, also fixes a hostname lookup problem when using systems that have a too strict getnameinfo(). Also print the CPS directive information. Print out symbolic system names that don't have strsignal(), but do have sys_siglist[]. Fix a potential crasher in xtimer_add(). Add %q and %ll modifiers to the sio library for displaying quad_t's or long long's. Restructure the argument parsing a little to reduce global memory usage. Fixed bug in service parameter verification. Prior versions did not verify that all require attributes were specified. Disable the service when a parse error is detected for its configuration. (Steve Grubb) 2.3.5 Included patch from Trond at RedHat to check signal pipe if there are no services running. Update the access_times parser to disable service if there is a parse error. Also corrected ti_add too. -Steve Grubb Updated all parsers to propagate errors so service will be disabled. -Steve Grubb Updated internal services to check the signal pipe periodically. -Steve Grubb Updated sendsig to wait for termed children so zombies aren't created and ports are clear to rebind to on hard_reconfig. -Steve Grubb Included a patch from Hendrik Visage for a problem with ident. 2.3.6 Updated only_from to 'and' both the remote address and the specified portion if a network mask type address is used. -Steve Grubb Updated explicit_mask to chose NUMERIC_ADDR if mask is 32. -Steve Grubb Many parser updates. -Steve Grubb Propogate default attributes even if not specified. log_on_success, log_on_failure, passenv were the main items affected by this problem. only_from and no_access now conform to this new propogation technique. -Steve Grubb Xremove now uses domain names in addition to ip addresses. -Steve Grubb Moved sensor code into its own file and changed it to use timer facility. -Steve Grubb Reworked remote_addr check & addrlist_match to not cache IP addresses and corrected several algorithmic problems. -Steve Grubb Off-by-one error corrected in pset_delete. -Steve Grubb Updated attrfill to use IPv4 addresses if bind specified. -Steve Grubb Fixed bug in libwrap code to check server better for NULL -Steve Grubb Added better testing of configuration if NAMEINARGS flag is set. -Steve Grubb Updated config.guess & config.sub. -Thomas Seyrat Added an rpm spec file. -Steve Grubb Removed sio/suite directory. It appears that key files have been deleted in the past so it no longer works. -Steve Grubb Make the file descriptor buffer allocation dynamic. This substantially reduces xinetd's normal memory footprint (~760KB). -Rob Braun Work around bugs in Mac OS X's getrlimit/setrlimit which causes them to be almost unusable. -Rob Braun 2.3.7 Added fixes or workarounds for issues introduced after 2.3.3 including the signal pipe leak into child processes (a security hole). -Solar Designer Made xinetd unlink its pidfile when there turns out to be no services configured on reload. -Solar Designer 2.3.8 Reworked redirect to better detect problems in its configuration. Also, redirect now allows service names for port numbers. -Steve Grubb Reworked attribute checking in confparse & updated attr.h. -Steve Grubb Ensure that children have the default signal handlers installed. Added support for DNS service registration ala Rendezvous. Fixed some compile errors on Mac OS X, FreeBSD, and OpenBSD. Added preliminary support for tcpmux -Philip Armstrong Update the xinetd man page to document the -version option. Now ignores the --with-inet6 compile option. Services will default to IPv4 unless configured otherwise. Bring back the inetd.conf parser in a different form. Parse all the xinetd config files first, then parse /etc/inetd.conf, and add services from there (if it exists). Use the -inetd_compat option to read inetd.conf. IPv6 updates for bind_parser, only_from, and no_access. -Steve Grubb 2.3.9 Fixed bug uncovered by IPv6 updates for bind parser. In the id_parser, a test was being performed for uniqueness. It relied on the address already being given. However, the address may not be known if more than one record came back from the getaddrinfo function call. -Steve Grubb Added code to service_fill to resolve port if unspecified. -Steve Grubb Consolidated duplicate services tests into check_entry. -Steve Grubb Fixed a bug with access control & internal services. Make sure we byteswap the value returned by time services. Fix an omission with the tcpmux integration. Fixed a race when there's 1 service configured and it is a wait service. 2.3.10 Close the service descriptors on fork. This only matters for internal forking services, since anything that calls exec() will get those closed automagically. This will help reduce the file discriptors used by the daemon when using some internal services Fix a numbering bug with xinetd's internal flag representation that was manifesting its self as all services being disabled upon recieving a SIGUSR2 (hard reconfig) Don't pass a hostname to dns registration calls, it'll pick a hostname automagically. Remove CLEANUP and other dead code. Make sure tcp internal non-forking services close their filedescriptors. Added syslog facilities for the xinetd log configuration to match SUS. - Steve Grubb Start reporting the Per Source value when dumping debugging output - Steve Grubb Correct the fake-getnameinfo.h to include appropriate macros. - Steve Grubb Up the default CPS value to 50 from 10. Document the default CPS values in the xinetd.conf man page. Fix a closing of the connection when there's an error handling the service. - Steve Grubb Fixed a bug in the includedir path where a reference was kept to free()'d memory. Fixed a bug in the consistency check mechanism where it would report the signal pipe as a problem. Clear memory before freeing it. This isn't strictly necessary, but aids in debugging. Add the pid to debugging messages. Remove access control calls for special services. The access control functions must always allow these services anyway. Fixed a bug with reconfiguring services using the interface attribute. -- Adam Lukosek Fixed a bug with deallocating dns registrations. Fixed a bug where tcp_wrappers would not identify an internal service since the internal service has no executable. -Steve Grubb Sclose was being used on the config file descriptor. Since sio never touches the descriptor, it failed to close it. - Steve Grubb Fix a potential memory leak with bind_addr and service reconfig. - Andrey Alekseyev Fix a reconfig timing issue. - Andrey Alekseyev 2.3.11 Fix some compile time errors on Solaris Fixed a bounds check in Sdone(). Patch from Dmitry V. Levin Added FreeBSD loadavg support. Patch from Vanilla I. Shu TCPMUX parser updates. -Steve Grubb TCPMUX was causing core dumps due to changes made in 2.3.10's child_process(), reverted changes. -Philip Armstrong Remove RECORD logging option. -Steve Grubb Change Sclose to make sure it always closes the fd. -Steve Grubb Added better error handling to filelog.c. -Steve Grubb Error messages now go to syslog instead of stderr in strparse.c. -Steve Grubb Fixed memory leaks found with valgrind. -Steve Grubb Correct problems with bind specified in the default section. -Steve Grubb Use Sclose to close banner commands. -Jay Fenlason Correct banner to match man pages. -Jay Fenlason 2.3.12 Cleanup some signal handling if not defined. -MARUYAMA Shinichi Make ident protocol work properly for multi-homed hosts. -Alan Sundell Code cleanup for const warnings. -Steve Grubb Make redirect protocol independent. -Cougar Make reconfig iterate over all services. Some may be in "not started" state and were being missed. -Steve Grubb Make redirected, forking builtins, & tcpmux close all listening descriptors so reconfig works. -Jay Fenlason Add support for the IPV6_V6ONLY socket option. Don't assume a default setting, as the default seems to be in flux. Address compare in readjust was wrong. Its now corrected to handle each address family separately. -Steve Grubb Add command line option to not fork. This will allow xinetd to be started by init or daemontools. -Matthias Andree Fixed a leak in reconfig. If log_type = file is used for a service and SIGHUP is sent to xinetd, it leaked a file descriptor and 44 bytes of memory per service using FILE. -Steve Grubb Change all close() calls to Sclose() to prevent future problems. -Steve Grubb Fixed bug if service name is unparsable and in an included directory that caused xinetd to core dump. -Steve Grubb Fixed bug where address lists had "version" uninitialized when the list used hostnames with no dots in the name. -Steve Grubb Numerous memory leaks when parsing errors occurred. -Steve Grubb Remove the servers and xadmin internal services. Update addrlist_match to use the address part of the IPv6 address structure. -Christof Meerwald Correct looping problems for udp connections rejected by the child access controls. -Steve Grubb Added TRAFFIC logging option to report total bytes in and out for a redirected service. -Christof Meerwald Correct a double-free condition if a retry was scheduled. -Steve Grubb Add filename to parse messages. -Steve Grubb Improve port error messages after parsing. -Steve Grubb Sclose dump_fd if SIO error causes dump abort. -Steve Grubb Smorefds wasn't allocating the proper amount of sio descriptor space if the fd was > 5 over its last known fd. -Steve Grubb 2.3.13 Add NULL entry to success_log_options to properly end the nvlist. -Steve Grubb Portability updates to libportable.h. -Matthias Andree Occasionally Smorefds didn't allocate more fds as expected. -Jay Fenlason Address list parsing considered the comma in factorized addresses to be an error. Updated test to allow factorized address. -Steve Grubb When parsing inet.conf, the filename wasn't being set for subsequent messages. -Steve Grubb Fix addrlist_match to correctly handle IPv4 mapped IPv6 addresses. -Christof Meerwald Fixed a bug where reloading configuration would core dump if file logging was enabled in defaults and a connection existed when SIGHUP was received. -Steve Grubb If too many connections hit and exhausts the file descriptors such that accept fails, deactivate the service like the cps access control does. This problem was reported by David Cook. -Steve Grubb Updated rpm.spec file and added default config files to contrib directory. -Steve Grubb Allow group & user to be specified by numeric value. -Steve Grubb 2.3.14 Applied patch from Art Haas for gcc 3.5 compat. Flush the descriptor after writing a banner. -Jay Fenlason Don't assume char is signed in the udp drain() function -Don Provan If log remote user is on, a descriptor between 0-2 is likely to be opened. Call msg_suspend before dup'ing socket to avoid this bug. -Glen Johnson Added confparse() RPC patch from RedHat's RHEL4 srpm. Fixed some service release bugs with accesses to dangling pointers. Updated BACKLOG to 64 from 7 Updated xconv.pl to understand ":" in inetd.conf files from FreeBSD ports patch. Added howl support for mdns advertising. Added a libwrap service attribute to specify the service name to check access via libwrap. Make some type cleanups to fix some warnings. Parse things as unsigned instead of signed where it makes sense. Based on a patch from Tony Ernst. Remove the <1024 port check for UDP builtin services. This check has been rather antiquated for years. 2.3.15 If the address we're binding to is a multicast address, do the multicast join. Merge the Fedora patch to turn off libwrap processing on tcp rpc services. Patch xinetd-2.3.12-tcp_rpc.patch. Merge the Fedora patch to add labeled networking. Patch xinetd-2.3.14-label.patch r1.4. Merge the Fedora patch to fix getpeercon() for labeled networking in MLS environments. Patch xinetd-2.3.14-contextconf.patch r1.1 Merge the Fedora patch for int->ssize_t. Patch xinetd-2.3.14-ssize_t.patch r1.1 Some modifications to this patch were necessary. Change compiler flags, -Wconversion generates excessive and unnecessary warnings with gcc, particularly all cases of ntohs(uint16_t). http://gcc.gnu.org/bugzilla/show_bug.cgi?id=6614 Additionally add -Wno-unused to prevent unnecessary warnings regarding unused function parameters when the function is a callback conforming to a standard interface. Change version number to 2.3.15devel, indicating an interim developmental source snapshot.
