The debdiff in attach seems to solve the problem. Without this fix applied:
$ sudo ./tools/testing/selftests/net/xfrm_policy.sh PASS: policy before exception matches FAIL: expected ping to .254 to fail (exceptions) ... With this fix applied: $ sudo ./tools/testing/selftests/net/xfrm_policy.sh PASS: policy before exception matches PASS: ping to .254 bypassed ipsec tunnel (exceptions) ... ** Patch added: "iptables-nft-fix-counters.debdiff" https://bugs.launchpad.net/ubuntu/+source/iptables/+bug/1949603/+attachment/5537896/+files/iptables-nft-fix-counters.debdiff -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to iptables in Ubuntu. https://bugs.launchpad.net/bugs/1949603 Title: iptables-save -c shows incorrect counters with iptables-nft Status in iptables package in Ubuntu: New Status in iptables source package in Impish: New Status in iptables source package in Jammy: New Bug description: Starting with Impish I noticed that the kernel selftest xfrm_policy.sh is always failing. Initially I thought it was a kernel issue, but debugging further I found that the reason is that with Impish we're using iptables-nft by default instead of iptables-legacy. This test (./tools/testing/selftests/net/xfrm_policy.sh in the kernel source directory) is creating a bunch of network namespaces and checking the iptables counters for the defined policies, in particular this is the interesting part: check_ipt_policy_count() { ns=$1 ip netns exec $ns iptables-save -c |grep policy | ( read c rest ip netns exec $ns iptables -Z if [ x"$c" = x'[0:0]' ]; then exit 0 elif [ x"$c" = x ]; then echo "ERROR: No counters" ret=1 exit 111 else exit 1 fi ) } If I use iptables-nft the counters are never [0:0] as they should be, so the test is failing. With iptables-legacy they are [0:0] and the test is passing. Any idea why this is happening and how I can debug this in iptables? Thanks in advance.
