Pull powerpc fixes from Michael Ellerman: - Fix a bad interaction between the scv handling and the fallback L1D flush, which could lead to user register corruption. Only affects people using scv (~no one) on machines with old firmware that are missing the L1D flush. - Two small selftest fixes. Thanks to Eirik Fuller, Libor Pechacek, Nicholas Piggin, Sandipan Das, and Tulio Magno Quites Machado Filho. * tag 'powerpc-5.11-5' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux: powerpc/64s: fix scv entry fallback flush vs interrupt selftests/powerpc: Only test lwm/stmw on big endian selftests/powerpc: Fix exit status of pkey tests

RHBZ 1848178 The original intent of returning an error in this function in the patch: "CIFS: Mask off signals when sending SMB packets" was to avoid interrupting packet send in the middle of sending the data (and thus breaking an SMB connection), but we also don't want to fail the request for non-fatal signals even before we have had a chance to try to send it (the reported problem could be reproduced e.g. by exiting a child process when the parent process was in the midst of calling futimens to update a file's timestamps). In addition, since the signal may remain pending when we enter the sending loop, we may end up not sending the whole packet before TCP buffers become full. In this case the code returns -EINTR but what we need here is to return -ERESTARTSYS instead to allow system calls to be restarted.

The culprit was kprobe_breakpoint_ss_handler() returning DBG_HOOK_ERROR which leads to the Unexpected kernel BRK exception. Reverting commit ba090f9c ("arm64: kprobes: Remove redundant kprobe_step_ctx") seemed to fix the problem for me. Further analysis showed that kcb->kprobe_status is set to KPROBE_REENTER when the error occurs. By teaching kprobe_breakpoint_ss_handler() to handle this status I can no longer reproduce the problem.

When unpacking the event which is from dynamic PMU, the array output[OUTPUT_TYPE_MAX] may be overrun. For example, type number of SKL uncore_imc is 10, but OUTPUT_TYPE_MAX is 7 now (OUTPUT_TYPE_MAX = PERF_TYPE_MAX + 1). /* In builtin-script.c */ process_event() { unsigned int type = output_type(attr->type); if (output[type].fields == 0) return; } output[10] is overrun. Create a type OUTPUT_TYPE_OTHER for dynamic PMU events, then output_type(attr->type) will return OUTPUT_TYPE_OTHER here. Note that if PERF_TYPE_MAX ever changed, then there would be a conflict between old perf.data files that had a dynamicaliy allocated PMU number that would then be the same as a fixed PERF_TYPE.

Joakim reports that getting "perf stat" for multiple system PMU metrics segfaults: $ perf stat -a -I 1000 -M imx8mm_ddr_write.all,imx8mm_ddr_write.all Segmentation fault $ While the same works without issue for a single metric. The logic in metricgroup__add_metric_sys_event_iter() is broken, in that add_metric() @m argument should be NULL for each new metric. Fix by not passing a holder for that, and rather make local in metricgroup__add_metric_sys_event_iter(). Fixes: be335ec2 ("perf metricgroup: Support adding metrics for system PMUs") Reported-by:

perf_evlist__set_sid_idx() updates perf_sample_id with the evlist map index, CPU number and TID. It is passed indexes to the evsel's cpu and thread maps, but references the evlist's maps instead. That results in using incorrect CPU numbers on heterogeneous systems. Fix it by using evsel maps. The id index (PERF_RECORD_ID_INDEX) is used by AUX area tracing when in sampling mode. Having an incorrect CPU number causes the trace data to be attributed to the wrong CPU, and can result in decoder errors because the trace data is then associated with the wrong process. Committer notes: Keep the class prefix convention in the function name, switching from perf_evlist__set_sid_idx() to perf_evsel__set_sid_idx().

This reverts commit 644bda6f ("dm table: fall back to getting device using name_to_dev_t()") dm_get_dev_t() is just used to convert an arbitrary 'path' string into a dev_t. It doesn't presume that the device is present; that check will be done later, as the only caller is dm_get_device(), which does a dm_get_table_device() later on, which will properly open the device. So if the path string already _is_ in major:minor representation we can convert it directly, avoiding a recursion into the filesystem to lookup the block device. This avoids a hang in multipath_message() when the filesystem is inaccessible.

Otherwise a malicious user could (ab)use the "recalculate" feature that makes dm-integrity calculate the checksums in the background while the device is already usable. When the system restarts before all checksums have been calculated, the calculation continues where it was interrupted even if the recalculate feature is not requested the next time the dm device is set up. Disable recalculating if we use internal_hash or journal_hash with a key (e.g. HMAC) and we don't have the "legacy_recalculate" flag. This may break activation of a volume, created by an older kernel, that is not yet fully recalculated -- if this happens, the user should add the "legacy_recalculate" flag to constructor parameters.
