Package: samba
Version: 3.0.22-1
Severity: normal
I say it's grave because the main smbd forks one child instance per
minute which will make the system crash after a while: a DOS attack!
Happens with cifs from kernel 2.6.16 and 2.6.17. NOTE: this bug is an
improvement against earlier kernels because they hung in a similar
situation and required a manual reboot.
When?
Use a cifs mount (via automount) on your local maschine (this is important:
when working over the network there is no such problem). The data source
itself should be automounted too (via automount again).
Do something via cifs to cause both automounts to mount.
Tell the non-cifs automount to unmount the real data. Tell the cifs
automount to unmount the cifs import.
Now umount.cifs should hang. THIS IS NOT THE REAL PROBLEM. I guess Steve
Frensh tries hard to fix these deadlock problems in his driver. He gets
better with each kernel release...
The problem:
While umount.cifs still hangs the main smbd forks one smdb child every
minute until the main smdb gets killed. If you don't kill it your system
will die as it will run out of resources. Also the syslog gets flooded
with useless CIFS VFS: no response for ... messages.
Yours Jürgen
