v1.5 - 2007-07-27

• Dmitry V. Levin ldv@altlinux.org
  • Close file descriptor in FindSymbolFile() in ksym.c in order not to leak file descriptors.
• Solar Designer solar@openwall.com
  • improve crunch_list()
  • Prevent potential buffer overflow in reading messages from the kernel log ringbuffer.
  • Ensure that "len" is not placed in a register, and that the endtty() signal handler is not installed too early which could cause a segmentation fault or worse.
• Steve Grubb linux_4ever@yahoo.com
  • fix memory calculation in crunch_list()
• Martin Schulze joey@infodrom.org
  • klogd will reconnect to the logger (mostly syslogd) after it went away
  • On heavily loaded system syslog will not spit out error messages anymore when recvfrom() results in EAGAIN
  • Makefile improvements
  • Local copy of module.h
  • Improved sysklogd.8
  • Always log with syslogd's timezone and locale
  • Remove trailing newline when forwarding messages
  • Continue working properly if /etc/service is missing and ignore network activity
  • Continue writing to log files as soon as space becomes available again after a filled up disk
  • Removed test to detect control characters > 0x20 as this prevented characters encoded in UTF-8 to be properly passed through
  • Only resolve the local domain when accepting messages from remote
  • Properly accompany the MARK message with the facility
  • Improved daemonise routine in klogd to stabilise startup
  • klogd will not change the console log level anymore unless -c is given
  • Added back /usr/src/linux/System.map as fall-back location
  • Rewrote the module symbol parser to read from /proc/kallsyms
  • Notify the waiting parent process if the client dies so it doesn't wait the entire five minutes.
  • Complete rewrite of the oops kernel module for Linux 2.6
  • Only read kernel symbols from /proc/kallsyms if no System.map has been read
  • Improved symbol lookup
  • Prevent named pipes from becoming the controlling tty
• Jon Burgess Jon_Burgess@eur.3com.com
  • Moved the installation of the signal handler up a little bit so it guaranteed to be available when the child is forked, hence, fixing a race condition. This used to create problems with UML and fast machines.
• Greg Trounson gregt@maths.otago.ac.nz
  • Improved README.linux
• Ulf H<>rnhammar Ulf.Harnhammar.9485@student.uu.se
  • Boundary check for fscanf() in InitKsyms() and CheckMapVersion()
• Colin Phipps cph@cph.demon.co.uk
  • Don't block on the network socket in case of packet loss
• Dirk Mueller mueller@kde.org
  • Don't crash when filesize limit is reached (e.g. without LFS)
• Miquel van Smoorenburg miquels@cistron.nl
  • Fix spurious hanging syslogd in connection with futex and NPTL introduced in recent glibc versions and Linux 2.6 (Details: http://bugs.debian.org/301511)
• Eric Tucker et@tallmaple.com
  • Improved syslog.conf(5) manpage
• Mike Frysinger vapier@gentoo.org
  • use socklen_t where appropriate
• Kelledin kelledin@skarpsey.dyndns.org
  • use newer query_module function rather than stepping through /dev/kmem.
• Matthew Fischer futhark@vzavenue.net
  • Remove special treatment of the percent sign in klogd

[v1.4.1][] - 2001-03-11

• klogd will set the console log level only if -c' is given on the commandline, not overwriting local settings in /etc/sysctl.conf'.
• Bugfix: klogd will use SOCK_DGRM as well, re-enables kernel logging
• Bugfix: Don't make syslogd fail with broken `-a'
• Bugfix: klogd will skip zero bytes and not enter a busy loop anymore
• Thomas Roessler roessler@does-not-exist.org
  • Patch to prevent LogLine() from being invoked with a negative counter as an argument.

v1.4 - 2000-09-19

• Skip newline when reading in klog messages
• Use lseek64() instead of llseek() which is deprecated these days
• Close symbol file before returning with 0 when an error occurred while reading it. This will enable systems to umount that partition with no open file descriptor left over.
• Solar Designer solar@false.com
  • printline() fixes
  • priority decoding fix
• Daniel Jacobowitz dan@debian.org
  • printchopped() fix
• Keith Owens kaos@ocs.com.au
  • Fixed bug that caused klogd to die if there is no sym_array available.
  • When symbols are expanded, print the line twice. Once with addresses converted to symbols, once with the raw text. Allows external programs such as ksymoops do their own processing on the original data.
• Olaf Kirch okir@caldera.de
  • Remove Unix Domain Sockets and switch to Datagram Unix Sockets
• Several bugfixes and improvements, please refer to the .c files
