["Brian C. Grayson" <bgrayson%netbsd.org@localhost>]

Module Name:    src
Committed By:   bgrayson
Date:           Sun Mar 28 00:46:47 UTC 1999

Modified Files:
        src/bin/ps: procfs_ops.c
Log Message:
- Be really paranoid.  Any time we open a file that is in /proc, run
fstatfs() on the open file to verify that no intruder has mounted
something on portions of /proc.  This will catch, for instance,
"mount_null /tmp /proc/1378".  We already do 5 syscalls per
process, so one more won't hurt :) ...  and safety is better than
performance when ps is otherwise broken.
- Also added a few close()'s at early returns, to avoid chewing up fd's.
