Subject: [PATCH 3/9] generic/314, afs: Allow for a filesystem that doesn't honour SGID inheritance
Date: Tue, 25 May 2021 14:34:09 +0100	[thread overview]
Message-ID: <162194964929.4011860.17079665160292202971.stgit@warthog.procyon.org.uk> (raw)
In-Reply-To: <162194962878.4011860.5561077785368723619.stgit@warthog.procyon.org.uk>

The AFS filesystem doesn't do any special handling for the SUID, SGID and
SVTX bits and doesn't perform any sort of propagation.  Further, only a
user with cell admin rights can set non-0777 bits.

Handle this by adding a "_require_sgid_inheritance" clause and labelling
the test with it, thereby skipping for filesystems that don't support it.
