B
Use real locking in ebtables (LP: #1645324)
- Prior use of locking by file exclusive access is inadequate
because if ebtables crashes or is killed it will leave a
stale lock file behind which then blocks new ebtables from
running.

As far as I understand the impact to the user was that a lock file from
a previous run prevents ebtables to run again.
Creating a "fix" that only removes the file on boot is not a fix
I have taken over this issue from Amad and have looked into the code.
The file exclusive create approach is a bad substitution for real
locking. I have a patch done that I am in the process of building a PPA
to test, this uses re

Hi Talat-
The bug was filed against vivid which is no longer maintained. The
original submitter had requested certain patches be back-ported to vivid
because they supposedly fixed an issue.
The requested patches were back-ported and they didn't fix the issue the
submitter purported that they fix.
Hi Kamal-
what is the status of this issue. Have you had a chance to try the
kernel with back-ported changes?
