1 Version 1.3 Patch Level 3
3 General. ------------------------------------------------------------------
4 Update to documentation including klogd.8 manpage to reflect new features.
6 Included patch for modules-2.0.0 package to provide support for signalling
7 klogd of changes in kernel module status.
9 klogd ---------------------------------------------------------------------
10 Provided support for signalling klogd to reload static and kernel module
11 symbol information via SIGUSR1 and SIGUSR2.
13 Implemented -p switch to cause a reload of kernel module symbol information
14 whenever a protection fault is detected.
16 Informative message is printed whenever klogd state change occurs.
18 Added -i and -I switches to signal the currently executing klogd daemon
19 to reload symbold information.
22 Version 1.3 Patch Level 2
24 General. ------------------------------------------------------------------
25 Added oops.c and oops_test.c. Oops.c implements a kernel loadable module
26 which will generate a general protection fault. The oops_test.c program
27 generates a test program for exercising the loadable module.
29 syslogd ------------------------------------------------------------------
30 Fixed bug resulting in file descriptors being orphaned when syslogd was
31 initialized via signal handler.
33 klogd ---------------------------------------------------------------------
34 Bug fix to prevent errors when reading symbol tables with 64 bit addresses.
36 Added support for debugging of protection faults occuring in kernel
40 Version 1.3 Patch Level 1
42 General. ------------------------------------------------------------------
43 Cleanups in the Makefile.
45 Patches to support compilation in the ALPHA environment. I have not
46 been able to test these personally so if anyone has any feedback I
47 would be interested in hearing from the Linux ALPHA community.
49 Spelling and grammar corrections in the man pages.
51 syslogd ------------------------------------------------------------------
52 Patch to fix parsing of hostnames in syslogd.c.
54 The return value of gethostbyname is now properly checked. This should
55 fix the problems with core dumps when name resolution failed.
57 Bounds error fixed when setting the file descriptors for UNIX domain
60 klogd ---------------------------------------------------------------------
61 Error checking and reporting enhanced. I have a couple of reports
62 that klogd is experiencing errors when reading the /proc filesystem.
63 Any additional information would be appreciated.
65 The sys_syslog function has been renamed to ksyslog. This was in a
66 set patches for ALPHA support so I am assuming that this is necessary
72 Numerous changes, performance enhancements, code cleanups and bug fixes.
73 Too many to individually summarize. Have a look at the top of each
74 source file for more information.
76 ** Default behavior of sysklogd is not to accept any message that
77 is sent via syslog/udp. To allow remote reception add -r to the
78 command-line arguments.
80 ** Spaces are now accepted in the syslog configuration file. This
81 should be a real crowd pleaser.
83 syslogd now uses dynamic allocation of logging output descriptors.
84 There is no longer a static limit on the number of log destinations
87 klogd supports on-the-fly kernel address to symbol translations.
88 This requires that a valid kernel symbol map be found at execution.
90 ** The default level for console log messages was changed to 6. This
91 means that kernel messages with a priority less than or equal to 5
92 (KERN_NOTICE) will be logged to the console.
94 This item has been flagged because it results in a behavior
95 change which will be different if version 1.3 replaces an
96 existing 1.2 binary. Linus strongly suggested that this
97 behavior be changed and in the 1.3.3x kernels Linus in fact
98 made it impossible to set the console log level lower than
101 There were good reasons from his perspective for doing so.
102 The most troublesome being that user's of packaged
103 distributions were not able to generate register dumps with
104 the kernel debugging keys, most notably altgr-SCRLCK.
106 If a kernels prior to 1.3.3x are being used the klogd daemon
107 invocation must be changed to something like: klogd -c 1
109 This will turn off logging of kernel messages to the console.
110 If you understand the ramifications of this the 1.3.3x kernels
111 can be patched to allow the suppression of console log
112 messages. It is important to be cognizant of the effects of
113 these changes. None the least of which is that Linus and Alan
114 will yell at you if you complain about not being able to
115 generate kernel debugging information.. :-)
117 ---------------------------------------------------------------------------
119 Fixes to both klogd and syslogd so that the package will compile without
120 errors due to the vararg procedures.
122 Modified pid files produced so that the names of the files are
123 klogd.pid and syslogd.pid respectively.
125 Fixed bug in klogd which prevented output from being directed to a file
126 when the program was compiled to auto-background itself. In the
127 auto-backgrounding configuration the forked process was closing all its
128 file descriptors which was causing the errant behavior.
130 Modified signal handling in klogd so that all signal are set to ignored
131 before establishing specific signal handlers.
133 Fixed bug in syslogd which was causing a delay in opening of the /dev/log
134 UNIX domain socket. This should correct the race condition which was
135 preventing klogd from properly logging kernel messages when the two
136 daemons were started in rapid succession.
138 Modified the closing/opening of file descriptors when syslogd was
139 compiled with auto-backgrounding support. Closes the potential for
140 a somewhat obscure bug caused by the /dev/log socket being opened on
143 Changed the names of the man pages from an extension of 1 to 8.
144 ---------------------------------------------------------------------------
146 Extensive changes and additional functionality added to klogd. Please
147 see sources and man-pages for documentation.
149 Fixed bugs in both syslogd and klogd with respect to fragmented
150 message re-assembly. Bootup messages should now be display properly.
152 Fixed bug in syslogd which prevented proper logging of messages with
153 priority classes of none and emerg.
155 Fixed bug which caused core dump when messages were logged to users.
156 Also fixed bug with messages to login type of LOGIN.
158 Fixed problem with zombies being left when messages were logged to
161 Enhanced functionality of syslog_tst program.
