Modified files:
sys/kern : kern_ktrace.c
Log message:
fix small (one stack word) kmem->user leak - the syscall code does
not zero retval when returning an error, so don't copy it back to a
ktracer in this case.
dropped by R00T-DUDE in his "Unusual and Hilarious Vulnerabilities" talk
at Ruxcon 2011; ok guenther@ miod@
