BTW, I noticed that even with the patch ps doesn't show all supplementary groups. For example,
root@mtdedicated:~# su - user1 -c 'grep Groups: /proc/self/status | wc' No directory, logging in with HOME=/ 1 482 2414 root@mtdedicated:~# su - user1 -c 'ps -e -o tid,supgid --sort supgid | grep 1049 | head -1 | wc' No directory, logging in with HOME=/ 1 48 242
Anyway, I'm pinging upstream just now.
