[PATCH] ct: endless loop when initializing netfilter/ct cache

[Holger Eitzenberger]

> I like the dup avoidance change to nl_cache_pickup() to work around
> this automatically but we can't modify the signature of
> nl_cache_pickup() as it breaks both API and ABI.
> 
> What we can do is add a new nl_cache_pickup_checkdup() which can be
> used from within flnl_lookup() to keep the DUP check and modify the
> standard behaviour of nl_cache_pickup() to not do a DUP check.

Please check attached patch.
