Mat Martineau says: ==================== mptcp: Some selftest improvements Here are a couple of selftest changes for MPTCP. Patch 1 fixes a mistake where the wrong protocol (TCP vs MPTCP) could be requested on the listening socket in some link failure tests.

2021-11-01selftests: mptcp: more stable simult_flows testsPaolo Abeni2-36/+72
Currently the simult_flows.sh self-tests are not very stable, especially when running on slow VMs. The tests measure runtime for transfers on multiple subflows and check that the time is near the theoretical maximum. The current test infra introduces a bit of jitter in test runtime, due to multiple explicit delays. Additionally the runtime is measured by the shell script wrapper. On a slow VM, the script overhead is measurable and subject to relevant jitter. One solution to make the test more stable would be adding more slack to the expected time; that could possibly hide real regressions. Instead move the measurement inside the command doing the transfer, and drop most unneeded sleeps.

2021-11-01ibmvnic: delay complete()Sukadev Bhattiprolu1-7/+9
If we get CRQ_INIT, we set errno to -EIO and first call complete() to notify the waiter. Then we try to schedule a FAILOVER reset. If this occurs while adapter is in PROBING state, ibmvnic_reset() changes the error code to EAGAIN and returns without scheduling the FAILOVER. The purpose of setting error code to EAGAIN is to ask the waiter to retry. But due to the earlier complete() call, the waiter may already have seen the -EIO response and decided not to retry. This can cause intermittent failures when bringing up ibmvnic adapters during boot, specially in in kexec/kdump kernels. Defer the complete() call until after scheduling the reset. Also streamline the error code to EAGAIN. Don't see why we need EIO sometimes. All 3 callers of ibmvnic_reset_init() can handle EAGAIN.

2021-11-01ibmvnic: Process crqs after enabling interruptsSukadev Bhattiprolu1-0/+3
Soon after registering a CRQ it is possible that we get a fail over or maybe a CRQ_INIT from the VIOS while interrupts were disabled. Look for any such CRQs after enabling interrupts. Otherwise we can intermittently fail to bring up ibmvnic adapters during boot, specially in kexec/kdump kernels.

2021-11-01ibmvnic: don't stop queue in xmitSukadev Bhattiprolu1-2/+0
If adapter's resetting bit is on, discard the packet but don't stop the transmit queue - instead leave that to the reset code. With this change, it is possible that we may get several calls to ibmvnic_xmit() that simply discard packets and return. But if we stop the queue here, we might end up doing so just after __ibmvnic_open() started the queues (during a hard/soft reset) and before the ->resetting bit was cleared. If that happens, there will be no one to restart queue and transmissions will be blocked indefinitely. This can cause a TIMEOUT reset and with auto priority failover enabled, an unnecessary FAILOVER reset to less favored backing device and then a FAILOVER back to the most favored backing device. If we hit the window repeatedly, we can get stuck in a loop of TIMEOUT, FAILOVER, FAILOVER resets leaving the adapter unusable for extended periods of time.

2021-10-31perf script: Fix PERF_SAMPLE_WEIGHT_STRUCT supportKan Liang1-1/+1
-F weight in perf script is broken. # ./perf mem record # ./perf script -F weight Samples for 'dummy:HG' event do not have WEIGHT attribute set. Cannot print 'weight' field. The sample type, PERF_SAMPLE_WEIGHT_STRUCT, is an alternative of the PERF_SAMPLE_WEIGHT sample type. They share the same space, weight. The lower 32 bits are exactly the same for both sample type. The higher 32 bits may be different for different architecture. For a new kernel on x86, the PERF_SAMPLE_WEIGHT_STRUCT is used. For an old kernel or other ARCHs, the PERF_SAMPLE_WEIGHT is used. With -F weight, current perf script will only check the input string "weight" with the PERF_SAMPLE_WEIGHT sample type. Because the commit ea8d0ed6eae3 ("perf tools: Support PERF_SAMPLE_WEIGHT_STRUCT") didn't update the PERF_SAMPLE_WEIGHT_STRUCT sample type for perf script. For a new kernel on x86, the check fails. Use PERF_SAMPLE_WEIGHT_TYPE, which supports both sample types, to replace PERF_SAMPLE_WEIGHT Fixes: ea8d0ed6eae37b01 ("perf tools: Support PERF_SAMPLE_WEIGHT_STRUCT") Reported-by: Joe Mario <[email protected]> Reviewed-by: Kajol Jain <[email protected]> Signed-off-by: Kan Liang <[email protected]> Tested-by: Jiri Olsa <[email protected]> Tested-by: Joe Mario <[email protected]> Acked-by: Jiri Olsa <[email protected]> Acked-by: Joe Mario <[email protected]> Cc: Andi Kleen <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Arnaldo Carvalho de Melo <[email protected]>

2021-10-31perf script: Check session->header.env.arch before using itSong Liu1-4/+8
When perf.data is not written cleanly, we would like to process existing data as much as possible (please see f_header.data.size == 0 condition in perf_session__read_header). However, perf.data with partial data may crash perf. Specifically, we see crash in 'perf script' for NULL session->header.env.arch. Fix this by checking session->header.env.arch before using it to determine native_arch. Also split the if condition so it is easier to read. Committer notes: If it is a pipe, we already assume is a native arch, so no need to check session->header.env.arch.
