Subject: BUG: Incompatibility between Samba & Secure kernels

Hi,

There is an incompatibility between Samba (tested version: 2.0.8) and
secure kernels (2.2.28 with security patch, available at
http://www.openwall.com/linux/)

The incompatibility seems to cause problems with shared memory, and
especially locks/sysv_shm_open

The diagnostic can be established in the smb logs:
  ERROR: Failed to initialise share modes
[2001/07/05 10:10:33, 0] locking/shmem_sysv.c:sysv_shm_open(667)

The problems are: random connection refused on port 139, causing the
server to appear "dead", and causing other network neighbourhood problems,
especially when samba is elected as browse master/domain master (the
whole network seems "down")

Once security disabled in the SECURITY section, everything seems to work
fine (no errors in the logs). I didn' have yet found exacly which
security option is causing this mess, but I can try to compile several
kernel releases and try to activate each option at time.

Is there a way to specify an option in smb.conf to disable shared memory,
or to disable shared memory automatically when secured kernels are being
used?
