Merge tag 'for-5.11/dm-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper fixes from Mike Snitzer: - Fix DM integrity crash if "recalculate" used without "internal_hash" - Fix DM integrity "recalculate" support to prevent recalculating checksums if we use internal_hash or journal_hash with a key (e.g. HMAC). Use of crypto as a means to prevent malicious corruption requires further changes and was never a design goal for dm-integrity's primary usecase of detecting accidental corruption. - Fix a benign dm-crypt copy-and-paste bug introduced as part of a fix that was merged for 5.11-rc4. - Fix DM core's dm_get_device() to avoid filesystem lookup to get block device (if possible). * tag 'for-5.11/dm-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: dm: avoid filesystem lookup in dm_get_dev_t() dm crypt: fix copy and paste bug in crypt_alloc_req_aead dm integrity: conditionally disable "recalculate" feature dm integrity: fix a crash if "recalculate" used without "internal_hash"

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:

Metrics containing duration_time cause a segfault: $ perf stat -v -M L1D_Cache_Fill_BW sleep 1 Using CPUID GenuineIntel-6-3D-4 metric expr 64 * l1d.replacement / 1000000000 / duration_time for L1D_Cache_Fill_BW found event duration_time found event l1d.replacement adding {l1d.replacement}:W,duration_time l1d.replacement -> cpu/umask=0x1,(null)=0x1e8483,event=0x51/ Segmentation fault $ In commit c2337d67 ("perf metricgroup: Fix metrics using aliases covering multiple PMUs"), the logic in find_evsel_group() when iter'ing events was changed to not only select events in same group, but also for aliased PMUs. Checking whether events were for aliased PMUs was done by comparing the event PMU name. This was not safe for duration_time event, which has no associated PMU (and no PMU name), so fix by checking if the event PMU name is set also. Committer testing: Reproduced the bug, then, on a: $ grep -m1 ^'model name' /proc/cpuinfo model name : Intel(R) Core(TM) i7-8650U CPU @ 1.90GHz $ We now get: $ perf stat -M L1D_Cache_Fill_BW sleep 1 Performance counter stats for 'sleep 1': 4,141 l1d.replacement:u 1,001,285,107 ns duration_time:u 1.001285107 seconds time elapsed 0.000000000 seconds user 0.001119000 seconds sys $ Detais from -v: Using CPUID GenuineIntel-6-8E-A metric expr 64 * l1d.replacement / 1000000000 / duration_time for L1D_Cache_Fill_BW found event duration_time found event l1d.replacement adding {l1d.replacement}:W,duration_time l1d.replacement -> cpu/(null)=0x1e8483,umask=0x1,event=0x51/ Control descriptor is not initialized Warning: kernel.perf_event_paranoid=2, trying to fall back to excluding kernel and hypervisor samples Warning: kernel.perf_event_paranoid=2, trying to fall back to excluding kernel and hypervisor samples l1d.replacement:u: 4592 612201 612201 duration_time:u: 1001478621 1001478621 1001478621 Fixes: c2337d67 ("perf metricgroup: Fix metrics using aliases covering multiple PMUs") Reported-by:Ian Rogers <irogers@google.com> Acked-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.

In commit d68b2958 ("dm crypt: use GFP_ATOMIC when allocating crypto requests from softirq") code was incorrectly copy and pasted from crypt_alloc_req_skcipher()'s crypto request allocation code to crypt_alloc_req_aead(). It is OK from runtime perspective as both simple encryption request pointer and AEAD request pointer are part of a union, but may confuse code reviewers.

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.
