It turns out it was never just gcc-11 that was broken. Apparently it just happens to work on x86-64 with other gcc versions. On arm64, I see warnings with gcc version 13.2.1, and the kernel test robot reports the same problem on s390 with gcc 13.2.0. Admittedly it seems to be just the new Xe drm driver, but this is keeping me from doing my normal arm64 build testing. So it gets reverted until somebody figures out what causes the problem (and why it doesn't show on x86-64, which is what makes me suspect it was never just about gcc-11, and more about just random happenstance). This also changes the Kconfig naming a bit - just make the "disable this for GCC" conditional be one simple Kconfig entry, and we can put the gcc version dependencies in that entry once we figure out what the correct rules are. The version dependency _may_ still end up being "gcc version larger than 11" if the issue is purely in the Xe driver, but even if that ends up the case, let's make that all part of the "GCC_NO_STRINGOP_OVERFLOW" logic. For now, we just disable it for all gcc versions while the exact cause is unknown. Link: https://lore.kernel.org/all/202401161031.hjGJHMiJ-lkp@intel.com/T/ Cc: Gustavo A. R.

Pull parisc architecture fixes from Helge Deller: "The current exception handler, which helps on kernel accesses to userspace, may exhibit data corruption. The problem is that it is not guaranteed that the compiler will use the processor register we specified in the source code, but may choose another register which then will lead to silent register- and data corruption.

Matthieu Baerts says: ==================== mptcp: fixes for recent issues reported by CI's This series of 9 patches fixes issues mostly identified by CI's not managed by the MPTCP maintainers. Thank you Linero (LKFT) and Netdev maintainers (NIPA) for running our kunit and selftests tests! For the first patch, it took a bit of time to identify the root cause. Some MPTCP Join selftest subtests have been "flaky", mostly in slow environments. It appears to be due to the use of a TCP-specific helper on an MPTCP socket. A fix for kernels >= v5.15. Patches 2 to 4 add missing kernel config to support NetFilter tables needed for IPTables commands. These kconfigs are usually enabled in default configurations, but apparently not for all architectures. Patches 2 and 3 can be backported up to v5.11 and the 4th one up to v5.19. Patch 5 increases the time limit for MPTCP selftests. It appears that many CI's execute tests in a VM without acceleration supports, e.g. QEmu without KVM. As a result, the tests take longer. Plus, there are more and more tests. This patch modifies the timeout added in v5.18. Patch 6 reduces the maximum rate and delay of the different links in some Simult Flows selftest subtests. The goal is to let slow VMs reach the maximum speed. The original rate was introduced in v5.11. Patch 7 lets CI changing the prefix of the subtests titles, to be able to run the same selftest multiple times with different parameters. With different titles, tests will be considered as different and not override previous results as it is the case with some CI envs. Subtests have been introduced in v6.6. Patch 8 and 9 make some MPTCP Join selftest subtests quicker by stopping the transfer when the expected events have been seen. Patch 8 can be backported up to v6.5. Signed-off-by:

Since the "Fixes" commits mentioned below, the newly added "userspace pm" subtests of mptcp_join selftests are launching the whole transfer in the background, do the required checks, then wait for the end of transfer. There is no need to wait longer, especially because the checks at the end of the transfer are ignored (which is fine). This saves quite a few seconds on slow environments.

If a CI executes the same selftest multiple times with different options, all results from the same subtests will have the same title, which confuse the CI. With the same title printed in TAP, the tests are considered as the same ones. Now, it is possible to override this prefix by using MPTCP_LIB_KSFT_TEST env var, and have a different title.

On very slow environments -- e.g. when QEmu is used without KVM --, mptcp_join.sh selftest can take a bit more than 20 minutes. Bump the default timeout by 50% as it seems normal to take that long on some environments. When a debug kernel config is used, this selftest will take even longer, but that's certainly not a common test env to consider for the timeout. The Fixes tag that has been picked here is there simply to help having this patch backported to older stable versions. It is difficult to point to the exact commit that made some env reaching the timeout from time to time.

When the MPTCP PM detects that a subflow is stale, all the packet scheduler must re-inject all the mptcp-level unacked data. To avoid acquiring unneeded locks, it first try to check if any unacked data is present at all in the RTX queue, but such check is currently broken, as it uses TCP-specific helper on an MPTCP socket. Funnily enough fuzzers and static checkers are happy, as the accessed memory still belongs to the mptcp_sock struct, and even from a functional perspective the recovery completed successfully, as the short-cut test always failed. A recent unrelated TCP change - commit d5fed5ad ("tcp: reorganize tcp_sock fast path variables") - exposed the issue, as the tcp field reorganization makes the mptcp code always skip the re-inection. Fix the issue dropping the bogus call: we are on a slow path, the early optimization proved once again to be evil.

However, if the addresses were never added to begin with due to some error in device setup, the test function currently passes. This is a false positive since in that situation the test did not actually exercise the intended functionality. Add a check that the expected addresses are indeed present after device setup. This makes the test function more robust. I noticed this problem when running the team/dev_addr_lists.sh test on a system without support for dummy and ipv6: tools/testing/selftests/drivers/net/team# ./dev_addr_lists.sh Error: Unknown device type. Error: Unknown device type. This program is not intended to be run as root.

Similar to commit dd2d40ac ("selftests: bonding: Add more missing config options"), add more networking-specific config options which are needed for team device tests. For testing, I used the minimal config generated by virtme-ng and I added the options in the config file. Afterwards, the team device test passed.

In commit ac504767 ("hv_netvsc: Disable NAPI before closing the VMBus channel"), napi_disable was getting called for all channels, including all subchannels without confirming if they are enabled or not. This caused hv_netvsc getting hung at napi_disable, when netvsc_probe() has finished running but nvdev->subchan_work has not started yet. netvsc_subchan_work() -> rndis_set_subchannel() has not created the sub-channels and because of that netvsc_sc_open() is not running. netvsc_remove() calls cancel_work_sync(&nvdev->subchan_work), for which netvsc_subchan_work did not run. netif_napi_add() sets the bit NAPI_STATE_SCHED because it ensures NAPI cannot be scheduled. Then netvsc_sc_open() -> napi_enable will clear the NAPIF_STATE_SCHED bit, so it can be scheduled. napi_disable() does the opposite. Now during netvsc_device_remove(), when napi_disable is called for those subchannels, napi_disable gets stuck on infinite msleep. This fix addresses this problem by ensuring that napi_disable() is not getting called for non-enabled NAPI struct. But netif_napi_del() is still necessary for these non-enabled NAPI struct for cleanup purpose.

Invoking the make_tx_response() / push_tx_responses() pair with no lock held would be acceptable only if all such invocations happened from the same context (NAPI instance or dealloc thread). Since this isn't the case, and since the interface "spec" also doesn't demand that multicast operations may only be performed with no in-flight transmits, MCAST_{ADD,DEL} processing also needs to acquire the response lock around the invocations. To prevent similar mistakes going forward, "downgrade" the present functions to private helpers of just the two remaining ones using them directly, with no forward declarations anymore. This involves renaming what so far was make_tx_response(), for the new function of that name to serve the new (wrapper) purpose. While there, - constify the txp parameters, - correct xenvif_idx_release()'s status parameter's type, - rename {,_}make_tx_response()'s status parameters for consistency with xenvif_idx_release()'s.

The documentation is pointing to the wrong path for the interface. Documentation is pointing to /sys/class/<iface>, instead of /sys/class/net/<iface>.

XDP queues are created/destroyed when a XDP program is attached/detached. In current driver xdp_queues are not getting destroyed on program exit due to incorrect xdp_queue and tot_tx_queue count values. This patch fixes the issue by setting tot_tx_queue and xdp_queue count to correct values. It also fixes xdp.data_hard_start address.

It appears that Sony DVMC-DA1 has a quirk that the descriptor leaf entry locates just after the vendor directory entry in root directory. This is not conformant to the legacy layout of configuration ROM described in Configuration ROM for AV/C Devices 1.0 (1394 Trading Association, Dec 2000, TA Document 1999027). This commit changes current implementation to parse configuration ROM for device attributes so that the descriptor leaf entry can be detected for the vendor name. $ config-rom-pretty-printer < Sony-DVMC-DA1.img ROM header and bus information block ----------------------------------------------------------------- 1024 041ee7fb bus_info_length 4, crc_length 30, crc 59387 1028 31333934 bus_name "1394" 1032 e0644000 irmc 1, cmc 1, isc 1, bmc 0, cyc_clk_acc 100, max_rec 4 (32) 1036 08004603 company_id 080046 | 1040 0014193c device_id 12886219068 | EUI-64 576537731003586876 root directory ----------------------------------------------------------------- 1044 0006b681 directory_length 6, crc 46721 1048 03080046 vendor 1052 0c0083c0 node capabilities: per IEEE 1394 1056 8d00000a --> eui-64 leaf at 1096 1060 d1000003 --> unit directory at 1072 1064 c3000005 --> vendor directory at 1084 1068 8100000a --> descriptor leaf at 1108 unit directory at 1072 ----------------------------------------------------------------- 1072 0002cdbf directory_length 2, crc 52671 1076 1200a02d specifier id 1080 13010000 version vendor directory at 1084 ----------------------------------------------------------------- 1084 00020cfe directory_length 2, crc 3326 1088 17fa0000 model 1092 81000008 --> descriptor leaf at 1124 eui-64 leaf at 1096 ----------------------------------------------------------------- 1096 0002c66e leaf_length 2, crc 50798 1100 08004603 company_id 080046 | 1104 0014193c device_id 12886219068 | EUI-64 576537731003586876 descriptor leaf at 1108 ----------------------------------------------------------------- 1108 00039e26 leaf_length 3, crc 40486 1112 00000000 textual descriptor 1116 00000000 minimal ASCII 1120 536f6e79 "Sony" descriptor leaf at 1124 ----------------------------------------------------------------- 1124 0005001d leaf_length 5, crc 29 1128 00000000 textual descriptor 1132 00000000 minimal ASCII 1136 44564d43 "DVMC" 1140 2d444131 "-DA1" 1144 00000000 Suggested-by:Adam Goldman <adamg@pobox.com> Tested-by:
