--------------------------------------------------------------------------- Version 1.11.0 (RGer), 2005-??-?? --------------------------------------------------------------------------- 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 1.0.1 (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 " 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 "" 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 * 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 * for sending me a patch. * * Mon May 20 13:29:32 MET DST 1996: Miquel van Smoorenburg * 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 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 * 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 . * * Thu Jan 1 16:04:52 CET 1998: Martin Schulze . * 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 for fiddling this out. * * Thu Jan 8 22:46:35 CET 1998: Martin Schulze * 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 * Fixed small bugs in F_FORW_UNKN meachanism. Thanks to Torsten * Neumann for pointing me to it. * * Mon Jan 12 19:50:58 CET 1998: Martin Schulze * Modified debug output concerning remote receiption. * * Mon Feb 23 23:32:35 CET 1998: Topi Miettinen * 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 * Fixed little comparison mistake that prevented the MARK * feature to work properly. * * Wed Feb 25 13:21:44 CET 1998: Martin Schulze * 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 * 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 * 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 * Redirected some error output with regard to argument parsing to * stderr. * * Mon Oct 12 14:02:51 CEST 1998: Martin Schulze * 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 * 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 * Code cleanups with regard to bsd -> posix transition and * stronger security (buffer length checking). Thanks to Topi * Miettinen * . index() --> strchr() * . sprintf() --> snprintf() * . bcopy() --> memcpy() * . bzero() --> memset() * . UNAMESZ --> UT_NAMESIZE * . sys_errlist --> strerror() * * Mon Oct 12 20:22:59 CEST 1998: Martin Schulze * 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 . * * Mon Oct 12 20:49:18 MET DST 1998: Martin Schulze * 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 * Modified printline() to support 8bit characters - such as * russion letters. Thanks to Vladas Lapinskas . * * Sat Nov 14 02:29:37 CET 1998: Martin Schulze * ``-m 0'' now turns of MARK logging entirely. * * Tue Jan 19 01:04:18 MET 1999: Martin Schulze * Finally fixed an error with `-a' processing, thanks to Topi * Miettinen . * * Sun May 23 10:08:53 CEST 1999: Martin Schulze * 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 * 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 * . * * Sun Sep 17 21:26:16 CEST 2000: Martin Schulze * Don't close open sockets upon reload. Thanks to Bill * Nottingham. * * Mon Sep 18 09:10:47 CEST 2000: Martin Schulze * Fixed bug in printchopped() that caused syslogd to emit * kern.emerg messages when splitting long lines. Thanks to * Daniel Jacobowitz for the fix. * * Mon Sep 18 15:33:26 CEST 2000: Martin Schulze * Removed unixm/unix domain sockets and switch to Datagram Unix * Sockets. This should remove one possibility to play DoS with * syslogd.
