====================
pull request (net): ipsec 2026-05-05

1. Fix an IPv6 encapsulation error path that leaked route references
   when UDPv6 ESP decapsulation resolved to an error route.
   From Yilin Zhu.

2. Fix AH with ESN on async crypto paths by accounting for the extra
   high-order sequence number when reconstructing the temporary
   authentication layout in the completion callbacks.
   From Michael Bomarito.

3. Fix XFRM output so it does not overwrite already-correct inner header
   pointers when a tunnel layer such as VXLAN has already saved them.
   The fix comes with new selftests. From Cosmin Ratiu.

4. Add the missing native payload size entry for XFRM_MSG_MAPPING in the
   compat translation path. From Ruijie Li.

5. Harden __xfrm_state_delete() against repeated or inconsistent unhashing
   of state list nodes by keying the removal on actual list membership and
   using delete-and-init helpers. From Michal Kosiorek.

6. Prevent ESP from decrypting shared splice-backed skb fragments in place
   by marking UDP splice frags as shared and forcing copy-on-write in ESP
   input when needed. From Kuan-Ting Chen.

selftests: drv-net: clarify linters and frameworks in README

2026-04-29T23:48:21+00:00

Minor clarifications in the README:
 - call out what linters we expect to be clean
 - make it clear that by "frameworks" we mean code under lib/

tools/selftests: Add a VXLAN+IPsec traffic test

2026-04-28T04:47:19+00:00

There are VXLAN tests and IPsec tests, but there is no test that
combines the two protocols and exercises the tunnel-over-ipsec code
paths. Fix that by adding a traffic test with VXLAN and IPsec using
crypto offload. This is runnable on HW which supports ESP offload (so no
nsim unfortunately).

Traffic is done with iperf3 and the test validates that there are no
packet drops and iperf3 can get to at least 100 Mbps (a very
conservative value on today's crypto offload HW, as it can typically
reach multi-Gbps rates).

Ran right now, the test fails due to a recently exposed bug in xfrm,
which will be fixed in the next patch:
 # ./tools/testing/selftests/drivers/net/hw/ipsec_vxlan.py

tools/selftests: Use a sensible timeout value for iperf3 client

2026-04-28T04:47:18+00:00

The default timeout of cmd() is 5 seconds and Iperf3Runner requests the
iperf3 client to run for 10 seconds, which clearly doesn't work since
commit [1] enforced the timeout parameter.

Use a value derived from duration as timeout (+5 seconds for
startup/teardown/various other overhead).

selftests: net: use ip commands instead of teamd in team rx_mode test

2026-04-21T10:50:25+00:00

Replace teamd daemon usage with ip link commands for team device
setup. teamd -d daemonizes and returns to the shell before port
addition completes, creating a race: the test may create the macvlan
(and check for its address on a slave) before teamd has finished
adding ports. This makes the test inherently dependent on scheduling
timing.

Using ip commands makes port addition synchronous, removing the race
and making the test deterministic.

selftests/net: Split netdevsim tests from HW tests in nk_qlease

2026-04-14T15:17:01+00:00

As pointed out in 3d2c3d2eea9a ("selftests: net: py: explicitly forbid
multiple ksft_run() calls"), ksft_run() cannot be called multiple times.

Move the netdevsim-based queue lease tests to selftests/net/ so that
each file has exactly one ksft_run() call.

The HW tests (io_uring ZC RX, queue attrs, XDP with MP, destroy) remain
in selftests/drivers/net/hw/.
