This - feature was not taken care of while rsyslogd evolved from sysklogd - and it was more or less defunct. Now it is fully functional again. -- added system properties: $NOW, $YEAR, $MONTH, $DAY, $HOUR, $MINUTE -- fixed a bug in iovAsString() that caused a memory leak under stress - conditions (most probably memory shortage). This was unlikely to - ever happen, but it doesn't hurt doing it right -- cosmetic: defined type "uchar", change all unsigned chars to uchar ---------------------------------------------------------------------------- -Version 1.15.0 (RGer), 2007-07-05 -- added ability to dynamically generate file names based on templates - and thus properties. This was a much-requested feature. It makes - life easy when it e.g. comes to splitting files based on the sender - address. -- added $umask and $FileCreateMode config file directives -- applied a patch from Bartosz Kuzma to compile cleanly under NetBSD -- checks for extra (unexpected) characters in system config file lines - have been added -- added IPv6 documentation - was accidently missing from CVS -- begun to change char to unsigned char ---------------------------------------------------------------------------- -Version 1.14.2 (RGer), 2007-07-03 -** this release fixes all known nits with IPv6 ** -- restored capability to do /etc/service lookup for "syslog" - service when -r 0 was given -- documented IPv6 handling of syslog messages -- integrate patch from Bartosz Kuźma to make rsyslog compile under - Solaris again (the patch replaced a strndup() call, which is not - available under Solaris -- improved debug logging when waiting on select -- updated rsyslogd man page with new options (-46A) ---------------------------------------------------------------------------- -Version 1.14.1 (RGer/Peter Vrabec), 2007-06-29 -- added Peter Vrabec's patch for IPv6 TCP -- prefixed all messages send to stderr in rsyslogd with "rsyslogd: " ---------------------------------------------------------------------------- -Version 1.14.0 (RGer/Peter Vrabec), 2007-06-28 -- Peter Vrabec provided IPv6 for rsyslog, so we are now IPv6 enabled - IPv6 Support is currently for UDP only, TCP is to come soon. - AllowedSender configuration does not yet work for IPv6. -- fixed code in iovCreate() that broke C's strict aliasing rules -- fixed some char/unsigned char differences that forced the compiler - to spit out warning messages -- updated the Red Hat init script to fix a known issue (thanks to - Peter Vrabec) ---------------------------------------------------------------------------- -Version 1.13.5 (RGer), 2007-06-22 -- made the TCP session limit configurable via command line switch - now -t <port>,<max sessions> -- added man page for rklogd(8) (basically a copy from klogd, but now - there is one...) -- fixed a bug that caused internal messages (e.g. rsyslogd startup) to - appear without a tag. -- removed a minor memory leak that occurred when TAG processing requalified - a HOSTNAME to be a TAG (and a TAG already was set). -- removed potential small memory leaks in MsgSet***() functions. There - would be a leak if a property was re-set, something that happened - extremely seldom. ---------------------------------------------------------------------------- -Version 1.13.4 (RGer), 2007-06-18 -- added a new property "PRI-text", which holds the PRI field in - textual form (e.g. "syslog.info") -- added alias "syslogseverity" for "syslogpriority", which is a - misleading property name that needs to stay for historical - reasons (and backward-compatility) -- added doc on how to record PRI value in log file -- enhanced signal handling in klogd, including removal of an unsafe - call to the logging system during signal handling ---------------------------------------------------------------------------- -Version 1.13.3 (RGer), 2007-06-15 -- create a version of syslog.c from scratch. This is now - - highly optimized for rsyslog - - removes an incompatible license problem as the original - version had a BSD license with advertising clause - - fixed in the regard that rklogd will continue to work when - rsysogd has been restarted (the original version, as well - as sysklogd, will remain silent then) - - solved an issue with an extra NUL char at message end that the - original version had -- applied some changes to klogd to care for the new interface -- fixed a bug in syslogd.c which prevented compiling under debian ---------------------------------------------------------------------------- -Version 1.13.2 (RGer), 2007-06-13 -- lib order in makefile patched to facilitate static linking - thanks - to Bennett Todd for providing the patch -- Integrated a patch from Peter Vrabec (pvrabec@redheat.com): - - added klogd under the name of rklogd (remove dependency on - original sysklogd package - - createDB.sql now in UTF - - added additional config files for use on Red Hat ---------------------------------------------------------------------------- -Version 1.13.1 (RGer), 2007-02-05 -- changed the listen backlog limit to a more reasonable value based on - the maximum number of TCP connections configurd (10% + 5) - thanks to Guy - Standen for the hint (actually, the limit was 5 and that was a - left-over from early testing). -- fixed a bug in makefile which caused DB-support to be disabled when - NETZIP support was enabled -- added the -e option to allow transmission of every message to remote - hosts (effectively turns off duplicate message suppression) -- (somewhat) improved memory consumption when compiled with MySQL support -- looks like we fixed an incompatibility with MySQL 5.x and above software - At least in one case, the remote server name was destroyed, leading to - a connection failure. The new, improved code does not have this issue and - so we see this as solved (the new code is generally somewhat better, so - there is a good chance we fixed this incompatibility). ---------------------------------------------------------------------------- -Version 1.13.0 (RGer), 2006-12-19 -- added '$' as ToPos proptery replacer specifier - means "up to the - end of the string" -- property replacer option "escape-cc", "drop-cc" and "space-cc" added -- changed the handling of \0 characters inside syslog messages. We now - consistently escape them to "#000". This is somewhat recommended in - the draft-ietf-syslog-protocol-19 draft. While the real recomendation - is to not escape any characters at all, we can not do this without - considerable modification of the code. So we escape it to "#000", which - is consistent with a sample found in the Internet-draft. -- removed message glue logic (see printchopped() comment for details) - Also caused removal of parts table and thus some improvements in - memory usage. -- changed the default MAXLINE to 2048 to take care of recent syslog - standardization efforts (can easily be changed in syslogd.c) -- added support for byte-counted TCP syslog messages (much like - syslog-transport-tls-05 Internet Draft). This was necessary to - support compression over TCP. -- added support for receiving compressed syslog messages -- added support for sending compressed syslog messages -- fixed a bug where the last message in a syslog/tcp stream was - lost if it was not properly terminated by a LF character ---------------------------------------------------------------------------- -Version 1.12.3 (RGer), 2006-10-04 -- implemented some changes to support Solaris (but support is not - yet complete) -- commented out (via #if 0) some methods that are currently not being use - but should be kept for further us -- added (interim) -u 1 option to turn off hostname and tag parsing -- done some modifications to better support Fedora -- made the field delimiter inside property replace configurable via - template -- fixed a bug in property replacer: if fields were used, the delimitor - became part of the field. Up until now, this was barely noticable as - the delimiter as TAB only and thus invisible to a human. With other - delimiters available now, it quickly showed up. This bug fix might cause - some grief to existing installations if they used the extra TAB for - whatever reasons - sorry folks... Anyhow, a solution is easy: just add - a TAB character contstant into your template. Thus, there has no attempt - been made to do this in a backwards-compatible way. ---------------------------------------------------------------------------- -Version 1.12.2 (RGer), 2006-02-15 -- fixed a bug in the RFC 3339 date formatter. An extra space was added - after the actual timestamp -- added support for providing high-precision RFC3339 timestamps for - (rsyslogd-)internally-generated messages -- very (!) experimental support for syslog-protocol internet draft - added (the draft is experimental, the code is solid ;)) -- added support for field-extracting in the property replacer -- enhanced the legacy-syslog parser so that it can interpret messages - that do not contain a TIMESTAMP -- fixed a bug that caused the default socket (usually /dev/log) to be - opened even when -o command line option was given -- fixed a bug in the Debian sample startup script - it caused rsyslogd - to listen to remote requests, which it shouldn't by default ---------------------------------------------------------------------------- -Version 1.12.1 (RGer), 2005-11-23 -- made multithreading work with BSD. Some signal-handling needed to be - restructured. Also, there might be a slight delay of up to 10 seconds - when huping and terminating rsyslogd under BSD -- fixed a bug where a NULL-pointer was passed to printf() in logmsg(). -- fixed a bug during "make install" where rc3195d was not installed - Thanks to Bennett Todd for spotting this. -- fixed a bug where rsyslogd dumped core when no TAG was found in the - received message -- enhanced message parser so that it can deal with missing hostnames - in many cases (may not be totally fail-safe) -- fixed a bug where internally-generated messages did not have the correct - TAG ---------------------------------------------------------------------------- -Version 1.12.0 (RGer), 2005-10-26 -- moved to a multi-threaded design. single-threading is still optionally - available. Multi-threading is experimental! -- fixed a potential race condition. In the original code, marking was done - by an alarm handler, which could lead to all sorts of bad things. This - has been changed now. See comments in syslogd.c/domark() for details. -- improved debug output for property-based filters -- not a code change, but: I have checked all exit()s to make sure that - none occurs once rsyslogd has started up. Even in unusual conditions - (like low-memory conditions) rsyslogd somehow remains active. Of course, - it might loose a message or two, but at least it does not abort and it - can also recover when the condition no longer persists. -- fixed a bug that could cause loss of the last message received - immediately before rsyslogd was terminated. -- added comments on thread-safety of global variables in syslogd.c -- fixed a small bug: spurios printf() when TCP syslog was used -- fixed a bug that causes rsyslogd to dump core on termination when one - of the selector lines did not receive a message during the run (very - unlikely) -- fixed an one-too-low memory allocation in the TCP sender. Could result - in rsyslogd dumping core. -- fixed a bug with regular expression support (thanks to Andres Riancho) -- a little bit of code restructuring (especially main(), which was - horribly large) ---------------------------------------------------------------------------- -Version 1.11.1 (RGer), 2005-10-19 -- support for BSD-style program name and host blocks -- added a new property "programname" that can be used in templates -- added ability to specify listen port for rfc3195d -- fixed a bug that rendered the "startswith" comparison operation - unusable. -- changed more functions to "static" storage class to help compiler - optimize (should have been static in the first place...) -- fixed a potential memory leak in the string buffer class destructor. - As the destructur was previously never called, the leak did not actually - appear. -- some internal restructuring in anticipation/preparation of minimal - multi-threading support -- rsyslogd still shares some code with the sysklogd project. Some patches - for this shared code have been brought over from the sysklogd CVS. ---------------------------------------------------------------------------- -Version 1.11.0 (RGer), 2005-10-12 -- support for receiving messages via RFC 3195; added rfc3195d for that - purpose -- added an additional guard to prevent rsyslogd from aborting when the - 2gb file size limit is hit. While a user can configure rsyslogd to - handle such situations, it would abort if that was not done AND large - file support was not enabled (ok, this is hopefully an unlikely scenario) -- fixed a bug that caused additional Unix domain sockets to be incorrectly - processed - could lead to message loss in extreme cases ---------------------------------------------------------------------------- -Version 1.10.2 (RGer), 2005-09-27 -- added comparison operations in property-based filters: - * isequal - * startswith -- added ability to negate all property-based filter comparison operations - by adding a !-sign right in front of the operation name -- added the ability to specify remote senders for UDP and TCP - received messages. Allows to block all but well-known hosts -- changed the $-config line directives to be case-INsensitive -- new command line option -w added: "do not display warnings if messages - from disallowed senders are received" -- fixed a bug that caused rsyslogd to dump core when the compare value - was not quoted in property-based filters -- fixed a bug in the new CStr compare function which lead to invalid - results (fortunately, this function was not yet used widely) -- added better support for "debugging" rsyslog.conf property filters - (only if -d switch is given) -- changed some function definitions to static, which eventually enables - some compiler optimizations -- fixed a bug in MySQL code; when a SQL error occured, rsyslogd could - run in a tight loop. This was due to invalid sequence of error reporting - and is now fixed. ---------------------------------------------------------------------------- -Version 1.10.1 (RGer), 2005-09-23 -- added the ability to execute a shell script as an action. - Thanks to Bjoern Kalkbrenner for providing the code! -- fixed a bug in the MySQL code; due to the bug the automatic one-time - retry after an error did not happen - this lead to error message in - cases where none should be seen (e.g. after a MySQL restart) -- fixed a security issue with SQL-escaping in conjunction with - non-(SQL-)standard MySQL features. ---------------------------------------------------------------------------- -Version 1.10.0 (RGer), 2005-09-20 - REMINDER: 1.10 is the first unstable version if the 1.x series! -- added the capability to filter on any property in selector lines - (not just facility and priority) -- changed stringbuf into a new counted string class -- added support for a "discard" action. If a selector line with - discard (~ character) is found, no selector lines *after* that - line will be processed. -- thanks to Andres Riancho, regular expression support has been - added to the template engine -- added the FROMHOST property in the template processor, which could - previously not be obtained. Thanks to Cristian Testa for pointing - this out and even providing a fix. -- added display of compile-time options to -v output -- performance improvement for production build - made some checks - to happen only during debug mode -- fixed a problem with compiling on SUSE and - while doing so - removed - the socket call to set SO_BSDCOMPAT in cases where it is obsolete. ---------------------------------------------------------------------------- -Version 1.0.4 (RGer), 2006-02-01 -- a small but important fix: the tcp receiver had two forgotten printf's - in it that caused a lot of unnecessary output to stdout. This was - important enough to justify a new release ---------------------------------------------------------------------------- -Version 1.0.3 (RGer), 2005-11-14 -- added an additional guard to prevent rsyslogd from aborting when the - 2gb file size limit is hit. While a user can configure rsyslogd to - handle such situations, it would abort if that was not done AND large - file support was not enabled (ok, this is hopefully an unlikely scenario) -- fixed a bug that caused additional Unix domain sockets to be incorrectly - processed - could lead to message loss in extreme cases -- applied some patches available from the sysklogd project to code - shared from there -- fixed a bug that causes rsyslogd to dump core on termination when one - of the selector lines did not receive a message during the run (very - unlikely) -- fixed an one-too-low memory allocation in the TCP sender. Could result - in rsyslogd dumping core. -- fixed a bug in the TCP sender that caused the retry logic to fail - after an error or receiver overrun -- fixed a bug in init() that could lead to dumping core -- fixed a bug that could lead to dumping core when no HOSTNAME or no TAG - was present in the syslog message ---------------------------------------------------------------------------- -Version 1.0.2 (RGer), 2005-10-05 -- fixed an issue with MySQL error reporting. When an error occured, - the MySQL driver went into an endless loop (at least in most cases). ---------------------------------------------------------------------------- -Version 1.0.1 (RGer), 2005-09-23 -- fixed a security issue with SQL-escaping in conjunction with - non-(SQL-)standard MySQL features. ---------------------------------------------------------------------------- -Version 1.0.0 (RGer), 2005-09-12 -- changed install doc to cover daily cron scripts - a trouble source -- added rc script for slackware (provided by Chris Elvidge - thanks!) -- fixed a really minor bug in usage() - the -r option was still - reported as without the port parameter ---------------------------------------------------------------------------- -Version 0.9.8 (RGer), 2005-09-05 -- made startup and shutdown message more consistent and included the - pid, so that they can be easier correlated. Used syslog-protocol - structured data format for this purpose. -- improved config info in startup message, now tells not only - if it is listening remote on udp, but also for tcp. Also includes - the port numbers. The previous startup message was misleading, because - it did not say "remote reception" if rsyslogd was only listening via - tcp (but not via udp). -- added a "how can you help" document to the doc set ---------------------------------------------------------------------------- -Version 0.9.7 (RGer), 2005-08-15 -- some of the previous doc files (like INSTALL) did not properly - reflect the changes to the build process and the new doc. Fixed - that. -- changed syslogd.c so that when compiled without database support, - an error message is displayed when a database action is detected - in the config file (previously this was used as an user rule ;)) -- fixed a bug in the os-specific Makefiles which caused MySQL - support to not be compiled, even if selected ---------------------------------------------------------------------------- -Version 0.9.6 (RGer), 2005-08-09 -- greatly enhanced documentation. Now available in html format in - the "doc" folder and FreeBSD. Finally includes an install howto. -- improved MySQL error messages a little - they now show up as log - messages, too (formerly only in debug mode) -- added the ability to specify the listen port for udp syslog. - WARNING: This introduces an incompatibility. Formerly, udp - syslog was enabled by the -r command line option. Now, it is - "-r [port]", which is consistent with the tcp listener. However, - just -r will now return an error message. -- added sample startup scripts for Debian and FreeBSD -- added support for easy feature selection in the makefile. Un- - fortunately, this also means I needed to spilt the make file - for different OS and distros. There are some really bad syntax - differences between FreeBSD and Linux make. ---------------------------------------------------------------------------- -Version 0.9.5 (RGer), 2005-08-01 -- the "semicolon bug" was actually not (fully) solved in 0.9.4. One - part of the bug was solved, but another still existed. This one - is fixed now, too. -- the "semicolon bug" actually turned out to be a more generic bug. - It appeared whenever an invalid template name was given. With some - selector actions, rsyslogd dumped core, with other it "just" had - a small ressource leak with others all worked well. These anomalies - are now fixed. Note that they only appeared during system initaliziation - once the system was running, nothing bad happened. -- improved error reporting for template errors on startup. They are now - shown on the console and the start-up tty. Formerly, they were only - visible in debug mode. -- support for multiple instances of rsyslogd on a single machine added -- added new option "-o" --> omit local unix domain socket. This option - enables rsyslogd NOT to listen to the local socket. This is most - helpful when multiple instances of rsyslogd (or rsyslogd and another - syslogd) shall run on a single system. -- added new option "-i <pidfile>" which allows to specify the pidfile. - This is needed when multiple instances of rsyslogd are to be run. -- the new project home page is now online at www.rsyslog.com ---------------------------------------------------------------------------- -Version 0.9.4 (RGer), 2005-07-25 -- finally added the TCP sender. It now supports non-blocking mode, no - longer disabling message reception during connect. As it is now, it - is usable in production. The code could be more sophisticated, but - I've kept it short in anticipation of the move to liblogging, which - will lead to the removal of the code just written ;) -- the "exiting on signal..." message still had the "syslogd" name in - it. Changed this to "rsyslogd", as we do not have a large user base - yet, this should pose no problem. -- fixed "the semiconlon" bug. rsyslogd dumped core if a write-db action - was specified but no semicolon was given after the password (an empty - template was ok, but the semicolon needed to be present). -- changed a default for traditional output format. During testing, it - was seen that the timestamp written to file in default format was - the time of message reception, not the time specified in the TIMESTAMP - field of the message itself. Traditionally, the message TIMESTAMP is - used and this has been changed now. ---------------------------------------------------------------------------- -Version 0.9.3 (RGer), 2005-07-19 -- fixed a bug in the message parser. In June, the RFC 3164 timestamp - was not correctly parsed (yes, only in June and some other months, - see the code comment to learn why...) -- added the ability to specify the destination port when forwarding - syslog messages (both for TCP and UDP) -- added an very experimental TCP sender (activated by - @@machine:port in config). This is not yet for production use. If - the receiver is not alive, rsyslogd will wait quite some time until - the connection request times out, which most probably leads to - loss of incoming messages. - ---------------------------------------------------------------------------- -Version 0.9.2 (RGer), around 2005-07-06 -- I intended to change the maxsupported message size to 32k to - support IHE - but given the memory inefficiency in the usual use - cases, I have not done this. I have, however, included very - specific instructions on how to do this in the source code. I have - also done some testing with 32k messages, so you can change the - max size without taking too much risk. -- added a syslog/tcp receiver; we now can receive messages via - plain tcp, but we can still send only via UDP. The syslog/tcp - receiver is the primary enhancement of this release. -- slightly changed some error messages that contained a spurios \n at - the end of the line (which gives empty lines in your log...) - ---------------------------------------------------------------------------- -Version 0.9.1 (RGer) -- fixed code so that it compiles without errors under FreeBSD -- removed now unused function "allocate_log()" from syslogd.c -- changed the make file so that it contains more defines for - different environments (in the long term, we need a better - system for disabling/enabling features...) -- changed some printf's printing off_t types to %lld and - explicit (long long) casts. I tried to figure out the exact type, - but did not succeed in this. In the worst case, ultra-large peta- - byte files will now display funny informational messages on rollover, - something I think we can live with for the next 10 years or so... - ---------------------------------------------------------------------------- -Version 0.9.0 (RGer) -- changed the filed structure to be a linked list. Previously, it - was a table - well, for non-SYSV it was defined as linked list, - but from what I see that code did no longer work after my - modifications. I am now using a linked list in general because - that is needed for other upcoming modifications. -- fixed a bug that caused rsyslogd not to listen to anything if - the configuration file could not be read -- pervious versions disabled network logging (send/receive) if - syslog/udp port was not in /etc/services. Now defaulting to - port 514 in this case. -- internal error messages are now supported up to 256 bytes -- error message seen during config file read are now also displayed - to the attached tty and not only the console -- changed some error messages during init to be sent to the console - and/or emergency log. Previously, they were only seen if the - -d (debug) option was present on the command line. -- fixed the "2gb file issue on 32bit systems". If a file grew to - more than 2gb, the syslogd was aborted with "file size exceeded". - Now, defines have been added according to - http://www.daimi.au.dk/~kasperd/comp.os.linux.development.faq.html#LARGEFILE - Testing revealed that they work ;) - HOWEVER, if your file system, glibc, kernel, whatever does not - support files larger 2gb, you need to set a file size limit with - the new output channel mechanism. -- updated man pages to reflect the changes - ---------------------------------------------------------------------------- -Version 0.8.4 - -- improved -d debug output (removed developer-only content) -- now compiles under FreeBSD and NetBSD (only quick testing done on NetBSD) ---------------------------------------------------------------------------- -Version 0.8.3 - -- security model in "make install" changed -- minor doc updates ---------------------------------------------------------------------------- -Version 0.8.2 - -- added man page for rsyslog.conf and rsyslogd -- gave up on the concept of rsyslog being a "drop in" replacement - for syslogd. Now, the user installs rsyslogd and also needs to - adjust his system settings to this specifically. This also lead - to these changes: - * changed Makefile so that install now installs rsyslogd instead - of dealing with syslogd - * changed the default config file name to rsyslog.conf ---------------------------------------------------------------------------- -Version 0.8.1 - -- fixed a nasty memory leak (probably not the last one with this release) -- some enhancements to Makefile as suggested by Bennett Todd -- syslogd-internal messages (like restart) were missing the hostname - this has been corrected ---------------------------------------------------------------------------- -Version 0.8.0 - -Initial testing release. Based on the sysklogd package. Thanks to the -sysklogd maintainers for all their good work! ---------------------------------------------------------------------------- - ----------------------------------------------------------------------- -The following comments are from the stock syslogd.c source. They provide -some insight into what happened to the source before we forked -rsyslogd. However, much of the code already has been replaced and more -is to be replaced. So over time, these comments become less valuable. -I have moved them out of the syslogd.c file to shrink it, especially -as a lot of them do no longer apply. For historical reasons and -understanding of how the daemon evolved, they are probably still -helpful. ----------------------------------------------------------------------- -/* - * syslogd -- log system messages - * - * This program implements a system log. It takes a series of lines. - * Each line may have a priority, signified as "<n>" as - * the first characters of the line. If this is - * not present, a default priority is used. - * - * To kill syslogd, send a signal 15 (terminate). A signal 1 (hup) will - * cause it to reread its configuration file. - * - * Defined Constants: - * - * MAXLINE -- the maximum line length that can be handled. - * DEFUPRI -- the default priority for user messages - * DEFSPRI -- the default priority for kernel messages - * - * Author: Eric Allman - * extensive changes by Ralph Campbell - * more extensive changes by Eric Allman (again) - * - * Steve Lord: Fix UNIX domain socket code, added linux kernel logging - * change defines to - * SYSLOG_INET - listen on a UDP socket - * SYSLOG_UNIXAF - listen on unix domain socket - * SYSLOG_KERNEL - listen to linux kernel - * - * Mon Feb 22 09:55:42 CST 1993: Dr. Wettstein - * Additional modifications to the source. Changed priority scheme - * to increase the level of configurability. In its stock configuration - * syslogd no longer logs all messages of a certain priority and above - * to a log file. The * wildcard is supported to specify all priorities. - * Note that this is a departure from the BSD standard. - * - * Syslogd will now listen to both the inetd and the unixd socket. The - * strategy is to allow all local programs to direct their output to - * syslogd through the unixd socket while the program listens to the - * inetd socket to get messages forwarded from other hosts. - * - * Fri Mar 12 16:55:33 CST 1993: Dr. Wettstein - * Thanks to Stephen Tweedie (dcs.ed.ac.uk!sct) for helpful bug-fixes - * and an enlightened commentary on the prioritization problem. - * - * Changed the priority scheme so that the default behavior mimics the - * standard BSD. In this scenario all messages of a specified priority - * and above are logged. - * - * Add the ability to specify a wildcard (=) as the first character - * of the priority name. Doing this specifies that ONLY messages with - * this level of priority are to be logged. For example: - * - * *.=debug /usr/adm/debug - * - * Would log only messages with a priority of debug to the /usr/adm/debug - * file. - * - * Providing an * as the priority specifies that all messages are to be - * logged. Note that this case is degenerate with specifying a priority - * level of debug. The wildcard * was retained because I believe that - * this is more intuitive. - * - * Thu Jun 24 11:34:13 CDT 1993: Dr. Wettstein - * Modified sources to incorporate changes in libc4.4. Messages from - * syslog are now null-terminated, syslogd code now parses messages - * based on this termination scheme. Linux as of libc4.4 supports the - * fsync system call. Modified code to fsync after all writes to - * log files. - * - * Sat Dec 11 11:59:43 CST 1993: Dr. Wettstein - * Extensive changes to the source code to allow compilation with no - * complaints with -Wall. - * - * Reorganized the facility and priority name arrays so that they - * compatible with the syslog.h source found in /usr/include/syslog.h. - * NOTE that this should really be changed. The reason I do not - * allow the use of the values defined in syslog.h is on account of - * the extensions made to allow the wildcard character in the - * priority field. To fix this properly one should malloc an array, - * copy the contents of the array defined by syslog.h and then - * make whatever modifications that are desired. Next round. - * - * Thu Jan 6 12:07:36 CST 1994: Dr. Wettstein - * Added support for proper decomposition and re-assembly of - * fragment messages on UNIX domain sockets. Lack of this capability - * was causing 'partial' messages to be output. Since facility and - * priority information is encoded as a leader on the messages this - * was causing lines to be placed in erroneous files. - * - * Also added a patch from Shane Alderton (shane@ion.apana.org.au) to - * correct a problem with syslogd dumping core when an attempt was made - * to write log messages to a logged-on user. Thank you. - * - * Many thanks to Juha Virtanen (jiivee@hut.fi) for a series of - * interchanges which lead to the fixing of problems with messages set - * to priorities of none and emerg. Also thanks to Juha for a patch - * to exclude users with a class of LOGIN from receiving messages. - * - * Shane Alderton provided an additional patch to fix zombies which - * were conceived when messages were written to multiple users. - * - * Mon Feb 6 09:57:10 CST 1995: Dr. Wettstein - * Patch to properly reset the single priority message flag. Thanks - * to Christopher Gori for spotting this bug and forwarding a patch. - * - * Wed Feb 22 15:38:31 CST 1995: Dr. Wettstein - * Added version information to startup messages. - * - * Added defines so that paths to important files are taken from - * the definitions in paths.h. Hopefully this will insure that - * everything follows the FSSTND standards. Thanks to Chris Metcalf - * for a set of patches to provide this functionality. Also thanks - * Elias Levy for prompting me to get these into the sources. - * - * Wed Jul 26 18:57:23 MET DST 1995: Martin Schulze - * Linux' gethostname only returns the hostname and not the fqdn as - * expected in the code. But if you call hostname with an fqdn then - * gethostname will return an fqdn, so we have to mention that. This - * has been changed. - * - * The 'LocalDomain' and the hostname of a remote machine is - * converted to lower case, because the original caused some - * inconsistency, because the (at least my) nameserver did respond an - * fqdn containing of upper- _and_ lowercase letters while - * 'LocalDomain' consisted only of lowercase letters and that didn't - * match. - * - * Sat Aug 5 18:59:15 MET DST 1995: Martin Schulze - * Now no messages that were received from any remote host are sent - * out to another. At my domain this missing feature caused ugly - * syslog-loops, sometimes. - * - * Remember that no message is sent out. I can't figure out any - * scenario where it might be useful to change this behavior and to - * send out messages to other hosts than the one from which we - * received the message, but I might be shortsighted. :-/ - * - * Thu Aug 10 19:01:08 MET DST 1995: Martin Schulze - * Added my pidfile.[ch] to it to perform a better handling with - * pidfiles. Now both, syslogd and klogd, can only be started - * once. They check the pidfile. - * - * Sun Aug 13 19:01:41 MET DST 1995: Martin Schulze - * Add an addition to syslog.conf's interpretation. If a priority - * begins with an exclamation mark ('!') the normal interpretation - * of the priority is inverted: ".!*" is the same as ".none", ".!=info" - * don't logs the info priority, ".!crit" won't log any message with - * the priority crit or higher. For example: - * - * mail.*;mail.!=info /usr/adm/mail - * - * Would log all messages of the facility mail except those with - * the priority info to /usr/adm/mail. This makes the syslogd - * much more flexible. - * - * Defined TABLE_ALLPRI=255 and changed some occurrences. - * - * Sat Aug 19 21:40:13 MET DST 1995: Martin Schulze - * Making the table of facilities and priorities while in debug - * mode more readable. - * - * If debugging is turned on, printing the whole table of - * facilities and priorities every hexadecimal or 'X' entry is - * now 2 characters wide. - * - * The number of the entry is prepended to each line of - * facilities and priorities, and F_UNUSED lines are not shown - * anymore. - * - * Corrected some #ifdef SYSV's. - * - * Mon Aug 21 22:10:35 MET DST 1995: Martin Schulze - * Corrected a strange behavior during parsing of configuration - * file. The original BSD syslogd doesn't understand spaces as - * separators between specifier and action. This syslogd now - * understands them. The old behavior caused some confusion over - * the Linux community. - * - * Thu Oct 19 00:02:07 MET 1995: Martin Schulze - * The default behavior has changed for security reasons. The - * syslogd will not receive any remote message unless you turn - * reception on with the "-r" option. - * - * Not defining SYSLOG_INET will result in not doing any network - * activity, i.e. not sending or receiving messages. I changed - * this because the old idea is implemented with the "-r" option - * and the old thing didn't work anyway. - * - * Thu Oct 26 13:14:06 MET 1995: Martin Schulze - * Added another logfile type F_FORW_UNKN. The problem I ran into - * was a name server that runs on my machine and a forwarder of - * kern.crit to another host. The hosts address can only be - * fetched using the nameserver. But named is started after - * syslogd, so syslogd complained. - * - * This logfile type will retry to get the address of the - * hostname ten times and then complain. This should be enough to - * get the named up and running during boot sequence. - * - * Fri Oct 27 14:08:15 1995: Dr. Wettstein - * Changed static array of logfiles to a dynamic array. This - * can grow during process. - * - * Fri Nov 10 23:08:18 1995: Martin Schulze - * Inserted a new tabular sys_h_errlist that contains plain text - * for error codes that are returned from the net subsystem and - * stored in h_errno. I have also changed some wrong lookups to - * sys_errlist. - * - * Wed Nov 22 22:32:55 1995: Martin Schulze - * Added the fabulous strip-domain feature that allows us to - * strip off (several) domain names from the fqdn and only log - * the simple hostname. This is useful if you're in a LAN that - * has a central log server and also different domains. - * - * I have also also added the -l switch do define hosts as - * local. These will get logged with their simple hostname, too. - * - * Thu Nov 23 19:02:56 MET DST 1995: Martin Schulze - * Added the possibility to omit fsyncing of logfiles after every - * write. This will give some performance back if you have - * programs that log in a very verbose manner (like innd or - * smartlist). Thanks to Stephen R. van den Berg <srb@cuci.nl> - * for the idea. - * - * Thu Jan 18 11:14:36 CST 1996: Dr. Wettstein - * Added patche from beta-testers to stop compile error. Also - * added removal of pid file as part of termination cleanup. - * - * Wed Feb 14 12:42:09 CST 1996: Dr. Wettstein - * Allowed forwarding of messages received from remote hosts to - * be controlled by a command-line switch. Specifying -h allows - * forwarding. The default behavior is to disable forwarding of - * messages which were received from a remote host. - * - * Parent process of syslogd does not exit until child process has - * finished initialization process. This allows rc.* startup to - * pause until syslogd facility is up and operating. - * - * Re-arranged the select code to move UNIX domain socket accepts - * to be processed later. This was a contributed change which - * has been proposed to correct the delays sometimes encountered - * when syslogd starts up. - * - * Minor code cleanups. - * - * Thu May 2 15:15:33 CDT 1996: Dr. Wettstein - * Fixed bug in init function which resulted in file descripters - * being orphaned when syslogd process was re-initialized with SIGHUP - * signal. Thanks to Edvard Tuinder - * (Edvard.Tuinder@praseodymium.cistron.nl) for putting me on the - * trail of this bug. I am amazed that we didn't catch this one - * before now. - * - * Tue May 14 00:03:35 MET DST 1996: Martin Schulze - * Corrected a mistake that causes the syslogd to stop logging at - * some virtual consoles under Linux. This was caused by checking - * the wrong error code. Thanks to Michael Nonweiler - * <mrn20@hermes.cam.ac.uk> for sending me a patch. - * - * Mon May 20 13:29:32 MET DST 1996: Miquel van Smoorenburg <miquels@cistron.nl> - * Added continuation line supported and fixed a bug in - * the init() code. - * - * Tue May 28 00:58:45 MET DST 1996: Martin Schulze - * Corrected behaviour of blocking pipes - i.e. the whole system - * hung. Michael Nonweiler <mrn20@hermes.cam.ac.uk> has sent us - * a patch to correct this. A new logfile type F_PIPE has been - * introduced. - * - * Mon Feb 3 10:12:15 MET DST 1997: Martin Schulze - * Corrected behaviour of logfiles if the file can't be opened. - * There was a bug that causes syslogd to try to log into non - * existing files which ate cpu power. - * - * Sun Feb 9 03:22:12 MET DST 1997: Martin Schulze - * Modified syslogd.c to not kill itself which confuses bash 2.0. - * - * Mon Feb 10 00:09:11 MET DST 1997: Martin Schulze - * Improved debug code to decode the numeric facility/priority - * pair into textual information. - * - * Tue Jun 10 12:35:10 MET DST 1997: Martin Schulze - * Corrected freeing of logfiles. Thanks to Jos Vos <jos@xos.nl> - * for reporting the bug and sending an idea to fix the problem. - * - * Tue Jun 10 12:51:41 MET DST 1997: Martin Schulze - * Removed sleep(10) from parent process. This has caused a slow - * startup in former times - and I don't see any reason for this. - * - * Sun Jun 15 16:23:29 MET DST 1997: Michael Alan Dorman - * Some more glibc patches made by <mdorman@debian.org>. - * - * Thu Jan 1 16:04:52 CET 1998: Martin Schulze <joey@infodrom.north.de - * Applied patch from Herbert Thielen <Herbert.Thielen@lpr.e-technik.tu-muenchen.de>. - * This included some balance parentheses for emacs and a bug in - * the exclamation mark handling. - * - * Fixed small bug which caused syslogd to write messages to the - * wrong logfile under some very rare conditions. Thanks to - * Herbert Xu <herbert@gondor.apana.org.au> for fiddling this out. - * - * Thu Jan 8 22:46:35 CET 1998: Martin Schulze <joey@infodrom.north.de> - * Reworked one line of the above patch as it prevented syslogd - * from binding the socket with the result that no messages were - * forwarded to other hosts. - * - * Sat Jan 10 01:33:06 CET 1998: Martin Schulze <joey@infodrom.north.de> - * Fixed small bugs in F_FORW_UNKN meachanism. Thanks to Torsten - * Neumann <torsten@londo.rhein-main.de> for pointing me to it. - * - * Mon Jan 12 19:50:58 CET 1998: Martin Schulze <joey@infodrom.north.de> - * Modified debug output concerning remote receiption. - * - * Mon Feb 23 23:32:35 CET 1998: Topi Miettinen <Topi.Miettinen@ml.tele.fi> - * Re-worked handling of Unix and UDP sockets to support closing / - * opening of them in order to have it open only if it is needed - * either for forwarding to a remote host or by receiption from - * the network. - * - * Wed Feb 25 10:54:09 CET 1998: Martin Schulze <joey@infodrom.north.de> - * Fixed little comparison mistake that prevented the MARK - * feature to work properly. - * - * Wed Feb 25 13:21:44 CET 1998: Martin Schulze <joey@infodrom.north.de> - * Corrected Topi's patch as it prevented forwarding during - * startup due to an unknown LogPort. - * - * Sat Oct 10 20:01:48 CEST 1998: Martin Schulze <joey@infodrom.north.de> - * Added support for TESTING define which will turn syslogd into - * stdio-mode used for debugging. - * - * Sun Oct 11 20:16:59 CEST 1998: Martin Schulze <joey@infodrom.north.de> - * Reworked the initialization/fork code. Now the parent - * process activates a signal handler which the daughter process - * will raise if it is initialized. Only after that one the - * parent process may exit. Otherwise klogd might try to flush - * its log cache while syslogd can't receive the messages yet. - * - * Mon Oct 12 13:30:35 CEST 1998: Martin Schulze <joey@infodrom.north.de> - * Redirected some error output with regard to argument parsing to - * stderr. - * - * Mon Oct 12 14:02:51 CEST 1998: Martin Schulze <joey@infodrom.north.de> - * Applied patch provided vom Topi Miettinen with regard to the - * people from OpenBSD. This provides the additional '-a' - * argument used for specifying additional UNIX domain sockets to - * listen to. This is been used with chroot()'ed named's for - * example. See for http://www.psionic.com/papers/dns.html - * - * Mon Oct 12 18:29:44 CEST 1998: Martin Schulze <joey@infodrom.north.de> - * Added `ftp' facility which was introduced in glibc version 2. - * It's #ifdef'ed so won't harm with older libraries. - * - * Mon Oct 12 19:59:21 MET DST 1998: Martin Schulze <joey@infodrom.north.de> - * Code cleanups with regard to bsd -> posix transition and - * stronger security (buffer length checking). Thanks to Topi - * Miettinen <tom@medialab.sonera.net> - * . index() --> strchr() - * . sprintf() --> snprintf() - * . bcopy() --> memcpy() - * . bzero() --> memset() - * . UNAMESZ --> UT_NAMESIZE - * . sys_errlist --> strerror() - * - * Mon Oct 12 20:22:59 CEST 1998: Martin Schulze <joey@infodrom.north.de> - * Added support for setutent()/getutent()/endutend() instead of - * binary reading the UTMP file. This is the the most portable - * way. This allows /var/run/utmp format to change, even to a - * real database or utmp daemon. Also if utmp file locking is - * implemented in libc, syslog will use it immediately. Thanks - * to Topi Miettinen <tom@medialab.sonera.net>. - * - * Mon Oct 12 20:49:18 MET DST 1998: Martin Schulze <joey@infodrom.north.de> - * Avoid logging of SIGCHLD when syslogd is in the process of - * exiting and closing its files. Again thanks to Topi. - * - * Mon Oct 12 22:18:34 CEST 1998: Martin Schulze <joey@infodrom.north.de> - * Modified printline() to support 8bit characters - such as - * russion letters. Thanks to Vladas Lapinskas <lapinskas@mail.iae.lt>. - * - * Sat Nov 14 02:29:37 CET 1998: Martin Schulze <joey@infodrom.north.de> - * ``-m 0'' now turns of MARK logging entirely. - * - * Tue Jan 19 01:04:18 MET 1999: Martin Schulze <joey@infodrom.north.de> - * Finally fixed an error with `-a' processing, thanks to Topi - * Miettinen <tom@medialab.sonera.net>. - * - * Sun May 23 10:08:53 CEST 1999: Martin Schulze <joey@infodrom.north.de> - * Removed superflous call to utmpname(). The path to the utmp - * file is defined in the used libc and should not be hardcoded - * into the syslogd binary referring the system it was compiled on. - * - * Sun Sep 17 20:45:33 CEST 2000: Martin Schulze <joey@infodrom.ffis.de> - * Fixed some bugs in printline() code that did not escape - * control characters '\177' through '\237' and contained a - * single-byte buffer overflow. Thanks to Solar Designer - * <solar@false.com>. - * - * Sun Sep 17 21:26:16 CEST 2000: Martin Schulze <joey@infodrom.ffis.de> - * Don't close open sockets upon reload. Thanks to Bill - * Nottingham. - * - * Mon Sep 18 09:10:47 CEST 2000: Martin Schulze <joey@infodrom.ffis.de> - * Fixed bug in printchopped() that caused syslogd to emit - * kern.emerg messages when splitting long lines. Thanks to - * Daniel Jacobowitz <dan@debian.org> for the fix. - * - * Mon Sep 18 15:33:26 CEST 2000: Martin Schulze <joey@infodrom.ffis.de> - * Removed unixm/unix domain sockets and switch to Datagram Unix - * Sockets. This should remove one possibility to play DoS with - * syslogd. Thanks to Olaf Kirch <okir@caldera.de> for the patch. - * - * Sun Mar 11 20:23:44 CET 2001: Martin Schulze <joey@infodrom.ffis.de> - * Don't return a closed fd if `-a' is called with a wrong path. - * Thanks to Bill Nottingham <notting@redhat.com> for providing - * a patch. - * - * The following copyright and license applies to the original - * sysklogd package that was used as a basis for this release of - * rsyslogd.
