Subject: [PATCH nf 0/2] testing: selftests: nft_flowtable.sh: unbreak test script
Date: Tue, 16 Aug 2022 14:15:20 +0200	[thread overview]
Message-ID: <20220816121522.14278-1-fw@strlen.de> (raw)

nft_flowtable.sh fails most of the time since
2738d9d963bd1f0 ("netfilter: flowtable: move dst_check to packet path").
Arguably the test scripts way of detecting 'offloaded' vs 'offload
failed' was always flaky/broken.

These patches fix this up:
1. first patch moves to random netns names so we don't trip
   over existing 'ns1' name (too generic...).
2. second patch reworks the 'offload appears to be non-working'
   by means of packet counters.

Because counters are only incremented when a packet is handled
by the classic forward path, check that the counter is lower than
a given threshold (25% of file size).

    failure
