[Pkg-samba-maint] Bug#1005642: possible gross file corruption due to windows client cache poisoning

[Michael Tokarev]

Package: samba
Version: 2:4.13.13+dfsg-1~deb11u2
Severity: critical
Tags: patch upstream

Please see https://lists.samba.org/archive/samba/2022-February/239548.html and
https://lists.samba.org/archive/samba/2022-February/239577.html for the
description of the problem and how serious can it be, this bugreport:
https://bugzilla.samba.org/show_bug.cgi?id=14928
for the actual bug and the fixes.

3 patches mentioned at the end of the samba.org bugreport are needed for
bullseye version of samba to fix this (not counting first patch which
modifies the tests, and the last patch which just fixes comments - I
mean the actual code changes needed for the fix). First code fix has
a chunk for tests/ which also needs to be deleted for 4.13.

With these 3 patches, and adding
 nt_time_to_unix_timespec_raw at SAMBA_UTIL_0.0.1
to d/libwbclient0.symbols, our problem with windows profile corruption
immediately went away.

Gosh, that was gross...

Thanks,
