Subject: [PATCH] nft: cache: Reset genid when rebuilding cache
This is required in order to avoid a cache rebuild loop if
iptables-nft-restore is called with '--test' parameter and a dump
containing more than a single table.
If non-zero, __nft_build_cache() never updates genid and therefore the
incorrect genid (caused by increment in nft_action()) is never
corrected.
This is a RHEL-only fix, upstream rewrote the whole cache logic which
implicitly resolved this problem.
Fixes: 200bc39965149 ("nft: cache: Fix iptables-save segfault under stress")
