pa_stats is optional in dt bindings, make it optional in driver as well. Currently if pa_stats syscon regmap is not found driver returns -ENODEV. Fix this by not returning an error in case pa_stats is not found and continue generating ethtool stats without pa_stats.

Lay the groundwork to import into kselftests the over 150 packetdrill TCP/IP conformance tests on github.com/google/packetdrill. Florian recently added support for packetdrill tests in nf_conntrack, in commit a8a388c2 ("selftests: netfilter: add packetdrill based conntrack tests"). This patch takes a slightly different approach. It relies on ksft_runner.sh to run every *.pkt file in the directory. Any future imports of packetdrill tests should require no additional coding. Just add the *.pkt files. Initially import only two features/directories from github. One with a single script, and one with two. This was the only reason to pick tcp/inq and tcp/md5. The path replaces the directory hierarchy in github with a flat space of files: $(subst /,_,$(wildcard tcp/**/*.pkt)). This is the most straightforward option to integrate with kselftests. The Linked thread reviewed two ways to maintain the hierarchy: TEST_PROGS_RECURSE and PRESERVE_TEST_DIRS. But both introduce significant changes to kselftest infra and with that risk to existing tests. Implementation notes: - restore alphabetical order when adding the new directory to tools/testing/selftests/Makefile - imported *.pkt files and support verbatim from the github project, except for - update `source ./defaults.sh` path (to adjust for flat dir) - add SPDX headers - remove one author statement - Acknowledgment: drop an e (checkpatch) Tested: make -C tools/testing/selftests \ TARGETS=net/packetdrill \ run_tests make -C tools/testing/selftests \ TARGETS=net/packetdrill \ install INSTALL_PATH=$KSFT_INSTALL_PATH # in virtme-ng ./run_kselftest.sh -c net/packetdrill ./run_kselftest.sh -t net/packetdrill:tcp_inq_client.pkt Link: https://lore.kernel.org/netdev/20240827193417.2792223-1-willemdebruijn.kernel@gmail.com/Signed-off-by:

Support testcases that are themselves not executable, but need an interpreter to run them. If a test file is not executable, but an executable file ksft_runner.sh exists in the TARGET dir, kselftest will run ./ksft_runner.sh ./$BASENAME_TEST Packetdrill may add hundreds of packetdrill scripts for testing. These scripts must be passed to the packetdrill process. Have kselftest run each test directly, as it already solves common runner requirements like parallel execution and isolation (netns). A previous RFC added a wrapper in between, which would have to reimplement such functionality.

ag71xx_probe is registering ag71xx_interrupt as handler for gmac0/gmac1 interrupts. The handler is trying to use napi_schedule to handle the processing of packets. But the netif_napi_add for this device is called a lot later in ag71xx_probe. It can therefore happen that a still running gmac0/gmac1 is triggering the interrupt handler with a bit from AG71XX_INT_POLL set in AG71XX_REG_INT_STATUS. The handler will then call napi_schedule and the napi code will crash the system because the ag->napi is not yet initialized. The gmcc0/gmac1 must be brought in a state in which it doesn't signal a AG71XX_INT_POLL related status bits as interrupt before registering the interrupt handler. ag71xx_hw_start will take care of re-initializing the AG71XX_REG_INT_ENABLE. This will become relevant when dual GMAC devices get added here. Signed-off-by:

Kuniyuki Iwashima says: ==================== af_unix: Correct manage_oob() when OOB follows a consumed OOB. Recently syzkaller reported UAF of OOB skb. The bug was introduced by commit 93c99f21 ("af_unix: Don't stop recv(MSG_DONTWAIT) if consumed OOB skb is at the head.") but uncovered by another recent commit 8594d9b8 ("af_unix: Don't call skb_get() for OOB skb.").

syzbot reported use-after-free in unix_stream_recv_urg(). [0] The scenario is 1. send(MSG_OOB) 2. recv(MSG_OOB) -> The consumed OOB remains in recv queue 3. send(MSG_OOB) 4. recv() -> manage_oob() returns the next skb of the consumed OOB -> This is also OOB, but unix_sk(sk)->oob_skb is not cleared 5. recv(MSG_OOB) -> unix_sk(sk)->oob_skb is used but already freed The recent commit 8594d9b8 ("af_unix: Don't call skb_get() for OOB skb.") uncovered the issue. If the OOB skb is consumed and the next skb is peeked in manage_oob(), we still need to check if the skb is OOB. Let's do so by falling back to the following checks in manage_oob() and add the test case in selftest. Note that we need to add a similar check for SIOCATMARK.

When OOB skb has been already consumed, manage_oob() returns the next skb if exists. In such a case, we need to fall back to the else branch below. Then, we want to keep holding spin_lock(&sk->sk_receive_queue.lock). Let's move it out of if-else branch and add lightweight check before spin_lock() for major use cases without OOB skb.

This is a prep for the later fix. No functional change intended. Signed-off-by:

The next 2 patches both target the rockchip_canfd driver added in the last pull request to net-next. The first one is by Nathan Chancellor and fixes the return type of rkcanfd_start_xmit(), the second one is by me and fixes a 64 bit division on 32 bit platforms in rkcanfd_timestamp_init(). * tag 'linux-can-next-for-6.12-20240909' of git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can-next: can: rockchip_canfd: rkcanfd_timestamp_init(): fix 64 bit division on 32 bit platforms can: rockchip_canfd: fix return type of rkcanfd_start_xmit() net: can: cc770: Simplify parsing DT properties ==================== Link: https://patch.msgid.link/20240909063657.2287493-1-mkl@pengutronix.deSigned-off-by:

dev_pick_tx_cpu_id() has been introduced with two users by commit a4ea8a3d ("net: Add generic ndo_select_queue functions"). The use in AF_PACKET has been removed in 2019 by commit b71b5837 ("packet: rework packet_pick_tx_queue() to use common code selection") The other user was a Netlogic XLP driver, removed in 2021 by commit 47ac6f56 ("staging: Remove Netlogic XLP network driver"). It's relatively unlikely that any modern driver will need an .ndo_select_queue implementation which picks purely based on CPU ID and skips XPS, delete dev_pick_tx_cpu_id() Found by code inspection.

Matthieu Baerts says: ==================== selftests: mptcp: add time per subtests in TAP output Patches here add 'time=<N>ms' in the diagnostic data of the TAP output, e.g. ok 1 - pm_netlink: defaults addr list # time=9ms This addition is useful to quickly identify which subtests are taking a longer time than the others, or more than expected. Note that there are no specific formats to follow to show this time according to the TAP 13, TAP 14 and KTAP specifications, but we follow the format being parsed by NIPA [1]. Patch 1 modifies mptcp_lib.sh to add this support to all MPTCP selftests. Patch 2 removes the now duplicated info in mptcp_connect.sh Patch 3 slightly improves the precision of the first subtests in all MPTCP subtests. Patches 4 and 5 remove duplicated spaces in TAP output, for the TAP parsers that cannot handle them properly. v1: https://lore.kernel.org/20240902-net-next-mptcp-ksft-subtest-time-v1-0-f1ed499a11b1@kernel.org Link: https://github.com/linux-netdev/nipa/pull/36 ==================== Link: https://patch.msgid.link/20240906-net-next-mptcp-ksft-subtest-time-v2-0-31d5ee4f3bdf@kernel.orgSigned-off-by:

It is nice to have a visual alignment in the test output to present the different results, but it makes less sense in the TAP output that is there for computers. It sounds then better to remove the duplicated whitespaces in the TAP output, also because it can cause some issues with TAP parsers expecting only one space around the directive delimiter (#). While at it, change the variable name (result_msg) to something more explicit. Signed-off-by:

Just to slightly improve the precision of the duration of the first test. In mptcp_join.sh, the last append_prev_results is now done as soon as the last test is over: this will add the last result in the list, and get a more precise time for this last test. Reviewed-by:

It is now added by the MPTCP lib automatically, see the parent commit. The time in the TAP output might be slightly different from the one displayed before, but that's OK. Reviewed-by:

It adds 'time=<N>ms' in the diagnostic data of the TAP output, e.g. ok 1 - pm_netlink: defaults addr list # time=9ms This addition is useful to quickly identify which subtests are taking a longer time than the others, or more than expected. Note that there are no specific formats to follow to show this time according to the TAP 13 [1], TAP 14 [2] and KTAP [3] specifications. Let's then define this one here.
