[OpenWrt-Devel] /proc/<pid>/stat

[W. Michael Petullo]

According to the PROC(5) manpage, field five of /proc/<pid>/stat should
be the GID of the process with PID <pid>. Yet I find the following for
(e.g.) Postfix's pickup process:

5657 (pickup) S 1771 1771 1771 0 -1 4219136 170 0 0 0 0 0 0 0 20 0 1 0 3513070 24834048 524 18446744073709551615 4194304 4446388 140727413994400 140727413992112 139626969169172 0 0 16781312 8192 0 0 0 17 0 0 0 0 0 0 6543544 6546778 24240128 140727414001539 140727414001560 140727414001560 140727414001628 0

Here the fifth field is 1771. 1771 is the parent process ID, and is
definitely not a valid GID on the computer (not in /etc/group). Am I
going crazy, or is there something wrong in the kernel?

It does not seem possible to get a GID out of Busybox's ps. Is there
another way to identify the GID of a running process?
