Description

Probably due to docker weirdness.

The following tests FAILED:
41 - chown (Failed)
42 - chown-no-syscallbuf (Failed)
67 - cwd_inaccessible (Failed)
68 - cwd_inaccessible-no-syscallbuf (Failed)
419 - setuid (Failed)
420 - setuid-no-syscallbuf (Failed)
547 - unshare (Failed)
548 - unshare-no-syscallbuf (Failed)
765 - ttyname (Failed)
989 - chown-32 (Failed)
990 - chown-32-no-syscallbuf (Failed)
1015 - cwd_inaccessible-32 (Failed)
1016 - cwd_inaccessible-32-no-syscallbuf (Failed)
1367 - setuid-32 (Failed)
1368 - setuid-32-no-syscallbuf (Failed)
1495 - unshare-32 (Failed)
1496 - unshare-32-no-syscallbuf (Failed)
1713 - ttyname-32 (Failed)

The chown one at least is due to the getgroups call failing. Didn't look at any others yet.

Research direction

Start by reproducing the Docker test run and examining the failures for chown, cwd_inaccessible, setuid, unshare, and ttyname, including their -no-syscallbuf and -32 variants. Investigate the reported getgroups failure first, then determine the cause of the remaining failures. Done means the listed tests pass under Docker.
