Subject: [PATCH net 6/6] selftests: netfilter: packetdrill: avoid failure on HZ=100 kernel
Date: Tue, 16 Dec 2025 20:09:04 +0100 [thread overview]
Message-ID: <20251216190904.14507-7-fw@strlen.de> (raw)
In-Reply-To: <20251216190904.14507-1-fw@strlen.de>
packetdrill --ip_version=ipv4 --mtu=1500 --tolerance_usecs=1000000 --non_fatal packet conntrack_syn_challenge_ack.pkt
conntrack v1.4.8 (conntrack-tools): 1 flow entries have been shown.
conntrack_syn_challenge_ack.pkt:32: error executing `conntrack -f $NFCT_IP_VERSION \
-L -p tcp --dport 8080 | grep UNREPLIED | grep -q SYN_SENT` command: non-zero status 1
Affected kernel had CONFIG_HZ=100; reset packet was still sitting in
backlog.
Reported-by: Yi Chen <yiche@redhat.com>
Fixes: a8a388c2aae4 ("selftests: netfilter: add packetdrill based conntrack tests")
