sysklogd

ChangeLog for version 1.5

Releasedate: 2007-07-27

The sysklogd package has received a large number of internal improvements and corrections since the last release. The most significant changes are listed below.

• Fix file descriptor leak in klogd
• Improve argument list processing
• 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
• klogd will reconnect to the logger (mostly syslogd) after it went away during operation
• 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 manpage
• 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
• Rewrite the module symbol parser to read from /proc/kallsyms
• Notify the waiting parent process if the client dies
• 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
• Fixing a race condition in syslogd discovered in UML
• Improved README.linux
• Added boundary checks in klogd
• Don't block on the network socket in case of packet loss
• Don't crash when filesize limit is reached (e.g. without LFS)
• Fix spurious hanging syslogd in connection with futex and NPTL introduced in recent glibc versions and Linux 2.6 (details)
• Improved syslog.conf(5) manpage
• Use socklen_t where appropriate
• Use newer query_module function rather than stepping through /dev/kmem.
• Remove special treatment of the percent sign in klogd
