Description Stephen Cornell 2001-05-30 14:06:49 UTC
Description of Problem: 






By default, klogd doesn't check kernel symbol sanity, so can munge kernel oops data






How Reproducible:











Steps to Reproduce:



1. 



2. 



3. 







Actual Results:











Expected Results:











Additional Information:




In /etc/rc.d/init.d/syslog, klogd is run without the `-x' option, so uses System.map to translate kernel oops output.  Hosever, it does not check that System.map matches /proc/ksyms, so this data can be spurious.  It should either run with `-x' by default, or should check that System.map matches /proc/ksyms.  Or so the kernel hackers tell me.

Comment 1 Bill Nottingham 2001-05-30 14:57:04 UTC
klogd by default in 7.1 runs with the -2 option, to preserve one copy for
ksymoops.
