Description Bastien Nocera 2005-11-30 14:37:55 UTC
Same patch as RHEL3 should apply.

+++ This bug was initially created as a clone of Bug #174585 +++

In /proc/<PID>/stat, the second column contains the short process name in
between brackets. For example:
14734 (gnome-pty-helpe) S 14733 2917 2917 0 -1 8388608 210 0 0 0 0 0 0 0 17 0 1
0 2854587 2224128 153 4294967295 134512640 134520764 3214533232 0 582 0 0
805310466 16385 0 0 0 17 0 0 0

killall parses that second column using this fscanf pattern:
-      okay = fscanf (file, "%*d (%[^)]", comm) == 1;
As comm is only 16 chars long, killall will crash if a kernel module sets its
own name to be longer than that. Patch from sprabhu@redhat.com attached
