commit 5fe341d2d67afb7088edcb772b058c747ab341b1
Author: Jeremy Allison <jra at samba.org>
Date: Mon Mar 21 13:45:25 2022 -0700
s3: torture: Add 2 new tests SMB2-DEL-ON-CLOSE-NONWRITE-DELETE-NO, SMB2-DEL-ON-CLOSE-NONWRITE-DELETE-YES.
We currently allow setting the delete on close bit for
a directory containing only explicitly hidden/vetoed files
in the case where "delete veto files = yes" *and*
"delete veto files = no". For the "delete veto files = no"
case we should be denying setting the delete on close bit
when the client tries to set it (that's the only time Windows
looks at the bit and returns an error to the user). We
already do the in the dangling symlink case, we just
missed it in the !is_visible_fsp() case.
Mark SMB2-DEL-ON-CLOSE-NONWRITE-DELETE-NO as knownfail
for now.
