Incidentally here's a sample from my logs for ipc:
auditctl -a entry,always -S ipc
type=SYSCALL msg=audit(1115734892.933:11104482): syscall=117
arch=40000003
success=yes exit=0 a0=18 a1=9000e a2=100 a3=0 items=0 pid=22636
loginuid=525
uid=525 gid=525 euid=525 suid=525 fsuid=525 egid=525 sgid=525
fsgid=525
comm="firefox-bin" exe=/usr/lib/firefox-1.0.3/firefox-bin
There doesn't seem to be any supplemental records. I'll
investigate.
shmctl normally does have at least one supplemental record, is that
what
you
ran to generate this record?
