Description From 2010-02-02 11:04:41
See the user report below, Kyle Fransham finds that using flock to encase the
ebtables adjustment script reduced ebtables errors with dmesg "Wrong nr. of
counters requested"

Should test ourselves and fold a fix into 2.4 if possible.

Thanks again Kyle.

This patch enables an flock-based exclusive write-lock around ebtables
adjustments which Kyle reports reduces "kernel doesn't support a certain
ebtables extension" errors.
