Ah OK, thank you for the explanation. I thought git was used to do the cherry-pick + generate the patch for quilt. I'm still surprised quilt didn't accept these patches generated on top of the 6.6-y branch. (By "chance", did you not have conflicts because the patch 1/5 (commit 629b35a225b0 ("selftests: mptcp: display simult in extra_msg")) didn't get backported by accident? It is strange it is also missing in the v6.6.y branch.) >> I just tried on my side with the default merge strategy coming with Git >> 2.43.0, and it works: >> >> $ git fetch >> git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git >> refs/heads/linux-6.6.y >> $ git switch -c tmp FETCH_HEAD >> $ git rebase -i 2f39e4380e73~ ## to drop these 3 patches you added: >> # 2f39e4380e73 selftests: mptcp: connect: fix shellcheck warnings >> >> >> >> # bd3b5b0fff75 mptcp: don't overwrite sock_ops in mptcp_is_tcpsk() >> >> >> >> # f723f9449193 mptcp: don't account accept() of non-MPC client (...) >> $ git cherry-pick -xs \ >> 629b35a225b0 e3aae1098f10 e7c42bf4d320 8e2b8a9fa512 7a1b3490f47e >> Auto-merging tools/testing/selftests/net/mptcp/mptcp_join.sh >> (...) >> $ echo $? >> 0 >> >> But if I try the 3 patches you selected >> >> $ git reset --hard HEAD~5 >> $ git cherry-pick -xs e3aae1098f10 8e2b8a9fa512 7a1b3490f47e >> Auto-merging tools/testing/selftests/net/mptcp/mptcp_connect.sh >> (...) >> CONFLICT (content): Merge conflict in >> tools/testing/selftests/net/mptcp/mptcp_connect.sh >> error: could not apply 7a1b3490f47e... mptcp: don't account accept() >> of non-MPC client as fallback to TCP >> >> >> And the conflict makes sense: with the version that is currently in >> linux-6.6.y branch, the new check is done after having printed "OK", so >> that's not correct. >> >> >> I can share the 5 patches I applied without conflicts on top of the >> current linux-6.6.y branch, without the 3 patches you added today if it >> can help. > > How about just resending this one patch after the next 6.6.y release > that comes out in a day or so. No hurry, that can indeed wait for the next 6.6.y release. Just to be sure we are aligned: I suggested backporting these 5 commits: - 629b35a225b0 ("selftests: mptcp: display simult in extra_msg") - e3aae1098f10 ("selftests: mptcp: connect: fix shellcheck warnings") - e7c42bf4d320 ("selftests: mptcp: use += operator to append strings") - 8e2b8a9fa512 ("mptcp: don't overwrite sock_ops in mptcp_is_tcpsk()") - 7a1b3490f47e ("mptcp: don't account accept() of non-MPC client as fallback to TCP") But only these 3 got backported to 6.6.y: - e3aae1098f10 ("selftests: mptcp: connect: fix shellcheck warnings") - 8e2b8a9fa512 ("mptcp: don't overwrite sock_ops in mptcp_is_tcpsk()") - 7a1b3490f47e ("mptcp: don't account accept() of non-MPC client as fallback to TCP") The last commit ("mptcp: don't account accept() of non-MPC client as fallback to TCP") has a small problem in 6.6.y (only): - In case of issue, a message will say that the subtest is OK and not OK, and the TAP report will report that everything is OK with this subtest => that's OK, nothing critical, that's the tests. - We can solve that in the next 6.6 version by manually backporting commit e7c42bf4d320 ("selftests: mptcp: use += operator to append strings") and its dependence: commit 629b35a225b0 ("selftests: mptcp: display simult in extra_msg").
