Subject: Revert "netfilter: ensure number of counters is >0 in do_replace()"
From: Bernhard Thaler <bernhard.thaler@xxxxxxxx>
commit d26e2c9ffa385dd1b646f43c1397ba12af9ed431 upstream.
This partially reverts commit 1086bbe97a07 ("netfilter: ensure number of
counters is >0 in do_replace()") in net/bridge/netfilter/ebtables.c.
Setting rules with ebtables does not work any more with 1086bbe97a07 place.
There is an error message and no rules set in the end.
e.g.
~# ebtables -t nat -A POSTROUTING --src 12:34:56:78:9a:bc -j DROP
Unable to update the kernel. Two possible causes:
1. Multiple ebtables programs were executing simultaneously. The ebtables
userspace tool doesn't by default support multiple ebtables programs
running
Reverting the ebtables part of 1086bbe97a07 makes this work again.
