Kleber has identified the backport of commit 692d7b5d1f91 ("tls: Fix
recvmsg() to be able to peek across multiple records") as the
responsible for this regression.It turns out this commit has 4 fixups upstream, 3 of which can be easily cherry picked, while the fourth one seems related to TLS 1.3 support, which is not included in our 5.0 kernels yet. Picking those 3 commits allow the tests to pass without issues. ** Description changed: + [Impact] + Partial reads on TLS sockets will cause processes to wait indefinitively. + + [Test case] + Run tls net selftests from the kernel source tree. + + [Regression potential] + We only touch code on the TLS socket family itself, so regressions on subsystems other than the one we are fixing is highly unlikely. + + + -------------------- + Issue found on: linux-gke-5.0 - 5.0.0-1045.46 / 5.0.0-1044.45 linux-oem-osp1 - 5.0.0-1065.70 / 5.0.0-1064.69 The net test in ubuntu_kernel_selftests will timeout and gets killed, this issue does not exist in gke 5.0.0-1043.44 and oem-osp1 5.0.0-1063.68 (the net test passed with 5.0.0-1063.68 without any error) The test will hang here: Opening 127.0.0.1:9999 Opening INADDR_ANY:9999 bind: Address already in use Opening in6addr_any:9999 Opening INADDR_ANY:9999 bind: Address already in use Opening INADDR_ANY:9999 after closing ipv6 socket bind: Address already in use Timer expired (1800 sec.), nuking pid 27394 ERROR ubuntu_kernel_selftests.net ubuntu_kernel_selftests.net timestamp=1595327738 localtime=Jul 21 10:35:38 Test timeout expired, rc=15 END ERROR ubuntu_kernel_selftests.net ubuntu_kernel_selftests.net Please find the attachment for the complete test log. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1888381 Title: net test from ubuntu_kernel_selftest will timeout on B-5.0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-kernel-tests/+bug/1888381/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
