Another thing that came to mind is if we want to use EXPORT_SYMBOL_GPL() instead for the DRM KUnit helpers. But that's not related to this series.

[PATCH net-next 0/8] mptcp: MSG_FASTOPEN and TFO listener side support

by Matthieu Baerts

Before this series, only the initiator of a connection was able to combine both TCP FastOpen and MPTCP when using TCP_FASTOPEN_CONNECT socket option. These new patches here add (in theory) the full support of TFO with MPTCP, which means: - MSG_FASTOPEN sendmsg flag support (patch 1/8) - TFO support for the listener side (patches 2-5/8) - TCP_FASTOPEN socket option (patch 6/8) - TCP_FASTOPEN_KEY socket option (patch 7/8) To support TFO for the server side, a few preparation patches are needed (patches 2 to 5/8). Some of them were inspired by a previous work from Benjamin Hesmans. Note that TFO support with MPTCP has been validated with selftests (patch 8/8) but also with Packetdrill tests running with a modified but still very WIP version supporting MPTCP. Both the modified tool and the tests are available online: https://github.com/multipath-tcp/packetdrill/ Dmytro Shytyi (5): mptcp: add MSG_FASTOPEN sendmsg flag support mptcp: implement delayed seq generation for passive fastopen mptcp: add subflow_v(4,6)_send_synack() mptcp: add TCP_FASTOPEN sock option selftests: mptcp: mptfo Initiator/Listener Matthieu Baerts (1): mptcp: add support for TCP_FASTOPEN_KEY sockopt Paolo Abeni (2): mptcp: track accurately the incoming MPC suboption type mptcp: consolidate initial ack seq generation net/mptcp/Makefile | 2 +- net/mptcp/fastopen.c | 73 ++++++++ net/mptcp/options.c | 25 ++- net/mptcp/protocol.c | 39 +--- net/mptcp/protocol.h | 28 ++- net/mptcp/sockopt.c | 9 +- net/mptcp/subflow.c | 105 ++++++++--- .../selftests/net/mptcp/mptcp_connect.c | 171 +++++++++++++----- .../selftests/net/mptcp/mptcp_connect.sh | 21 +++ 9 files changed, 358 insertions(+), 115 deletions(-) create mode 100644 net/mptcp/fastopen.c Cc: Benjamin Hesmans <benjamin.hesmans(a)tessares.net> base-commit: a6e3d86ece0b42a571a11055ace5c3148cb7ce76 -- 2.37.2

[PATCH] kunit: tool: don't include KTAP headers and the like in the test log

by Daniel Latypov

We print the "test log" on failure. This is meant to be all the kernel output that happened during the test. But we also include the special KTAP lines in it, which are often redundant. E.g. we include the "not ok" line in the log, right before we print that the test case failed...

[PATCH v1 0/3] kselftest/arm64: fp-stress performance improvements

by Mark Brown

This series contains a few improvements to fp-stress performance, only noticable on emulated platforms which both run more slowly and are stressed far more by fp-stress due to supporting more VLs for SVE and SME. The bulk of the improvement comes from the first patch which reduces the amount of time the main fp-stress executable is swamped by load from the child processes during startup, the other two patches are much more marginal.

[PATCH v5 net-next 8/8] selftests: Add a basic HSR test.

This test adds a basic HSRv0 network with 3 nodes. In its current shape it sends and forwards packets, announcements and so merges nodes based on MAC A/B information. It is able to detect duplicate packets and packetloss should any occur.
