There's a cut'n'paste error in the logging for our test for reading register state back via ptrace, correctly say that we did a read instead of a write. Signed-off-by:

Currently we unconditionally test the ability to set the vector length inheritance flag via ptrace meaning that we generate false failures on systems that don't support SVE when we attempt to set the vector length there. Check the hwcap and mark the tests as skipped when it's not present. Fixes: 0ba1ce1e ("selftests: arm64: Add coverage of ptrace flags for SVE VL inheritance") Signed-off-by:

TRBE implementations affected by Arm erratum #1902691 might corrupt trace data or deadlock, when it's being written into the memory. So effectively TRBE is broken and hence cannot be used to capture trace data. This adds a new errata ARM64_ERRATUM_1902691 in arm64 errata framework.

TRBE implementations affected by Arm erratum #2038923 might get TRBE into an inconsistent view on whether trace is prohibited within the CPU. As a result, the trace buffer or trace buffer state might be corrupted. This happens after TRBE buffer has been enabled by setting TRBLIMITR_EL1.E, followed by just a single context synchronization event before execution changes from a context, in which trace is prohibited to one where it isn't, or vice versa. In these mentioned conditions, the view of whether trace is prohibited is inconsistent between parts of the CPU, and the trace buffer or the trace buffer state might be corrupted. This adds a new errata ARM64_ERRATUM_2038923 in arm64 errata framework.

In ex_handler_load_unaligned_zeropad() we erroneously extract the data and addr register indices from ex->type rather than ex->data. As ex->type will contain EX_TYPE_LOAD_UNALIGNED_ZEROPAD (i.e. 4): * We'll always treat X0 as the address register, since EX_DATA_REG_ADDR is extracted from bits [9:5]. Thus, we may attempt to dereference an arbitrary address as X0 may hold an arbitrary value. * We'll always treat X4 as the data register, since EX_DATA_REG_DATA is extracted from bits [4:0]. Thus we will corrupt X4 and cause arbitrary behaviour within load_unaligned_zeropad() and its caller. Fix this by extracting both values from ex->data as originally intended.

Pull ftrace fix from Steven Rostedt: "Fix s390 breakage from sorting mcount tables. The latest merge of the tracing tree sorts the mcount table at build time. But s390 appears to do things differently (like always) and replaces the sorted table back to the original unsorted one. As the ftrace algorithm depends on it being sorted, bad things happen when it is not, and s390 experienced those bad things. Add a new config to tell the boot if the mcount table is sorted or not, and allow s390 to opt out of it" * tag 'trace-v5.17-3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: ftrace: Fix assuming build time sort works for s390

To speed up the boot process, as mcount_loc needs to be sorted for ftrace to work properly, sorting it at build time is more efficient than boot up and can save milliseconds of time. Unfortunately, this change broke s390 as it will modify the mcount_loc location after the sorting takes place and will put back the unsorted locations. Since the sorting is skipped at boot up if it is believed that it was sorted at run time, ftrace can crash as its algorithms are dependent on the list being sorted. Add a new config BUILDTIME_MCOUNT_SORT that is set when BUILDTIME_TABLE_SORT but not if S390 is set. Use this config to determine if sorting should take place at boot up.

A previous patch preventing "attr->sample_period" values from being overridden in pfm events changed a related behaviour in arm-spe. Before said patch: perf record -c 10000 -e arm_spe_0// -- sleep 1 Would yield an SPE event with period=10000. After the patch, the period in "-c 10000" was being ignored because the arm-spe code initializes sample_period to a non-zero value. This patch restores the previous behaviour for non-libpfm4 events.

Perf script was failed to print the phys_addr for SPE profiling. One 'dummy' event is added by SPE profiling but it doesn't have PHYS_ADDR attribute set, perf script then exits with error. Now referring to 'addr', use evsel__do_check_stype() to check the type. Before: # perf record -e arm_spe_0/branch_filter=0,ts_enable=1,pa_enable=1,load_filter=1,jitter=0,\ store_filter=0,min_latency=0,event_filter=2/ -p 4064384 -- sleep 3 # perf script -F pid,tid,addr,phys_addr Samples for 'dummy:u' event do not have PHYS_ADDR attribute set.
