Oops.c implements a kernel loadable module +which will generate a general protection fault. The oops_test.c program +generates a test program for exercising the loadable module. + +syslogd ------------------------------------------------------------------ +Fixed bug resulting in file descriptors being orphaned when syslogd was +initialized via signal handler. + +klogd --------------------------------------------------------------------- +Bug fix to prevent errors when reading symbol tables with 64 bit addresses. + +Added support for debugging of protection faults occuring in kernel +loadable modules. + + +Version 1.3 Patch Level 1 + +General. ------------------------------------------------------------------ +Cleanups in the Makefile. + +Patches to support compilation in the ALPHA environment. I have not +been able to test these personally so if anyone has any feedback I +would be interested in hearing from the Linux ALPHA community. + +Spelling and grammar corrections in the man pages. + +syslogd ------------------------------------------------------------------ +Patch to fix parsing of hostnames in syslogd.c. + +The return value of gethostbyname is now properly checked. This should +fix the problems with core dumps when name resolution failed. + +Bounds error fixed when setting the file descriptors for UNIX domain +sockets. + +klogd --------------------------------------------------------------------- +Error checking and reporting enhanced. I have a couple of reports +that klogd is experiencing errors when reading the /proc filesystem. +Any additional information would be appreciated. + +The sys_syslog function has been renamed to ksyslog. This was in a +set patches for ALPHA support so I am assuming that this is necessary +for that environment + + +Version 1.3 + +Numerous changes, performance enhancements, code cleanups and bug fixes. +Too many to individually summarize. Have a look at the top of each +source file for more information. + +** Default behavior of sysklogd is not to accept any message that +is sent via syslog/udp. To allow remote reception add -r to the +command-line arguments. + +** Spaces are now accepted in the syslog configuration file. This +should be a real crowd pleaser. + +syslogd now uses dynamic allocation of logging output descriptors. +There is no longer a static limit on the number of log destinations +that can be defined. + +klogd supports on-the-fly kernel address to symbol translations. +This requires that a valid kernel symbol map be found at execution. + +** The default level for console log messages was changed to 6. This +means that kernel messages with a priority less than or equal to 5 +(KERN_NOTICE) will be logged to the console. + + This item has been flagged because it results in a behavior + change which will be different if version 1.3 replaces an + existing 1.2 binary. Linus strongly suggested that this + behavior be changed and in the 1.3.3x kernels Linus in fact + made it impossible to set the console log level lower than + about 5. + + There were good reasons from his perspective for doing so. + The most troublesome being that user's of packaged + distributions were not able to generate register dumps with + the kernel debugging keys, most notably altgr-SCRLCK. + + If a kernels prior to 1.3.3x are being used the klogd daemon + invocation must be changed to something like: klogd -c 1 + + This will turn off logging of kernel messages to the console. + If you understand the ramifications of this the 1.3.3x kernels + can be patched to allow the suppression of console log + messages. It is important to be cognizant of the effects of + these changes. None the least of which is that Linus and Alan + will yell at you if you complain about not being able to + generate kernel debugging information.. :-) + +--------------------------------------------------------------------------- +Version 1.2 +Fixes to both klogd and syslogd so that the package will compile without +errors due to the vararg procedures. + +Modified pid files produced so that the names of the files are +klogd.pid and syslogd.pid respectively. + +Fixed bug in klogd which prevented output from being directed to a file +when the program was compiled to auto-background itself. In the +auto-backgrounding configuration the forked process was closing all its +file descriptors which was causing the errant behavior. + +Modified signal handling in klogd so that all signal are set to ignored +before establishing specific signal handlers. + +Fixed bug in syslogd which was causing a delay in opening of the /dev/log +UNIX domain socket. This should correct the race condition which was +preventing klogd from properly logging kernel messages when the two +daemons were started in rapid succession. + +Modified the closing/opening of file descriptors when syslogd was +compiled with auto-backgrounding support. Closes the potential for +a somewhat obscure bug caused by the /dev/log socket being opened on +fd 0. + +Changed the names of the man pages from an extension of 1 to 8. +--------------------------------------------------------------------------- +Version 1.1 +Extensive changes and additional functionality added to klogd. Please +see sources and man-pages for documentation. + +Fixed bugs in both syslogd and klogd with respect to fragmented +message re-assembly. Bootup messages should now be display properly. + +Fixed bug in syslogd which prevented proper logging of messages with +priority classes of none and emerg. + +Fixed bug which caused core dump when messages were logged to users. +Also fixed bug with messages to login type of LOGIN. + +Fixed problem with zombies being left when messages were logged to +multiple users. + +Enhanced functionality of syslog_tst program. + +Added man-pages. +--------------------------------------------------------------------------- + +--------------------------------------------------------------------------- +Version 1.0 + +Initial release. +--------------------------------------------------------------------------- |
