I am getting following error.
" net/bridge/netfilter/ebtables.c:269 ebt_do_table()
   error: potential null derefence 'cs'"

     i = cs[sp].n;  // If cs == Null then this will cause problem.

Very sorry, I didn't see the out label.

I'll apply this to my nf [1] once David takes my previous request for
pulling.


Hi,

Has this patch been tested? Really, that code in the core firewall function is there for a reason, wouldn't you think? The chainstack is only allocated when user-defined chains are used (see translate_table).
Never blindly trust a tool.
