    sys/fs/procfs        procfs.c 
  MFC procfs.c revisions 1.13 and 1.14:
    1.13: Revision 1.4 set access for all sensitive files in /proc/<PID> to mode 0
    if a process's uid or gid has changed, but the /proc/<PID> directory
    itself was also set to mode 0.  Assuming this doesn't open any
    security holes, open access to the /proc/<PID> directory for users
    other than root to read or search the directory.
    1.14: Upon further review, DES prefers this change over that in revision 1.13
    to resolve the directory access problem for processes with P_SUGID flag
  Revision  Changes    Path  +4 -3      src/sys/fs/procfs/procfs.c
