2022-02-17tools/power/x86/intel-speed-select: v1.12 releaseSrinivas Pandruvada1-1/+2
This version allows out of band SST support, where some remote agent changes SST profiles via some Board Management Controller. Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com>
2022-02-17tools/power/x86/intel-speed-select: HFI supportSrinivas Pandruvada5-4/+324
Read HFI (Hardware Feedback Interface) events to process config level changes in oob mode. When HFI is supported there is no need for polling to check config level change. Subscribe to Linux thermal netlink messages and process message: THERMAL_GENL_EVENT_CPU_CAPABILITY_CHANGE. This message contains cpu number, performance and energy efficiency.

2022-02-17tools/power/x86/intel-speed-select: OOB daemon modeSrinivas Pandruvada4-11/+292
It is possible that some out of band agent changed config level. In this case CPUs need to be online/offline to support this config change. Add a command line option --oob, so that this tool can run as daemon and poll for config level change and take action. The poll interval is configurable in seconds using config option --poll-interval. Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com>

2022-02-16perf cs-etm: Fix corrupt inject files when only last branch option is enabledJames Clark1-0/+2
'perf inject' with Coresight data generates files that cannot be opened when only the last branch option is specified: perf inject -i perf.data --itrace=l -o inject.data perf script -i inject.data 0x33faa8 [0x8]: failed to process type: 9 [Bad address] This is because cs_etm__synth_instruction_sample() is called even when the sample type for instructions hasn't been setup. Last branch records are attached to instruction samples so it doesn't make sense to generate them when --itrace=i isn't specified anyway. This change disables all calls of cs_etm__synth_instruction_sample() unless --itrace=i is specified, resulting in a file with no samples if only --itrace=l is provided, rather than a bad file.

2022-02-16perf trace: Avoid early exit due SIGCHLD from non-workload processesChangbin Du1-5/+18
The function trace__symbols_init() runs "perf-read-vdso32" and that ends up with a SIGCHLD delivered to 'perf'. And this SIGCHLD make perf exit early. 'perf trace' should exit only if the SIGCHLD is from our workload process. So let's use sigaction() instead of signal() to match such condition. Committer notes: Use memset to zero the 'struct sigaction' variable as the '= { 0 }' method isn't accepted in many compiler versions, e.g.: 4 34.02 alpine:3.6 : FAIL clang version 4.0.0 (tags/RELEASE_400/final) builtin-trace.c:4897:35: error: suggest braces around initialization of subobject [-Werror,-Wmissing-braces] struct sigaction sigchld_act = { 0 }; ^ {} builtin-trace.c:4897:37: error: missing field 'sa_mask' initializer [-Werror,-Wmissing-field-initializers] struct sigaction sigchld_act = { 0 }; ^ 2 errors generated. 6 32.60 alpine:3.8 : FAIL gcc version 6.4.0 (Alpine 6.4.0) builtin-trace.c:4897:35: error: suggest braces around initialization of subobject [-Werror,-Wmissing-braces] struct sigaction sigchld_act = { 0 }; ^ {} builtin-trace.c:4897:37: error: missing field 'sa_mask' initializer [-Werror,-Wmissing-field-initializers] struct sigaction sigchld_act = { 0 }; ^ 2 errors generated. 7 34.82 alpine:3.9 : FAIL gcc version 8.3.0 (Alpine 8.3.0) builtin-trace.c:4897:35: error: suggest braces around initialization of subobject [-Werror,-Wmissing-braces] struct sigaction sigchld_act = { 0 }; ^ {} builtin-trace.c:4897:37: error: missing field 'sa_mask' initializer [-Werror,-Wmissing-field-initializers] struct sigaction sigchld_act = { 0 }; ^ 2 errors generated.

These can be used to place an MTE tag at an address that is not at a page size boundary. The kernel prior to 295cf156231c ("arm64: Avoid premature usercopy failure"), would infinite loop if an MTE tag was placed not at a PAGE_SIZE boundary.

But there is no precise (and stable across kernel changes) point at which the PASID_MSR is updated from the value for one task to the next. Kernel code that uses accelerators must always use the ENQCMDS instruction which does not access the PASID_MSR. Check for use of the ENQCMD instruction in the kernel and warn on its usage.

2022-02-14selftests/seccomp: Fix seccomp failure by adding missing headersSherry Yang1-1/+1
seccomp_bpf failed on tests 47 global.user_notification_filter_empty and 48 global.user_notification_filter_empty_threaded when it's tested on updated kernel but with old kernel headers. Because old kernel headers don't have definition of macro __NR_clone3 which is required for these two tests. Since under selftests/, we can install headers once for all tests (the default INSTALL_HDR_PATH is usr/include), fix it by adding usr/include to the list of directories to be searched. Use "-isystem" to indicate it's a system directory as the real kernel headers directories are.

The TH_LOG() macro is an optional debug logging function made available by kselftest itself. When TH_LOG_ENABLED is set it prints the provided message with additional information and formatting that already includes a newline. Providing a newline to the message printed by TH_LOG() results in a double newline that produces irregular test output. Remove the unnecessary newlines from the text provided to TH_LOG().

2022-02-12selftests/sgx: Fix NULL-pointer-dereference upon early test failureReinette Chatre1-4/+5
== Background == The SGX selftests track parts of the enclave binaries in an array: encl->segment_tbl[]. That array is dynamically allocated early (but not first) in the test's lifetime. The array is referenced at the end of the test in encl_delete(). == Problem == encl->segment_tbl[] can be NULL if the test fails before its allocation. That leads to a NULL-pointer-dereference in encl_delete(). This is triggered during early failures of the selftest like if the enclave binary ("test_encl.elf") is deleted. == Solution == Ensure encl->segment_tbl[] is valid before attempting to access its members. The offset with which it is accessed, encl->nr_segments, is initialized before encl->segment_tbl[] and thus considered valid to use after the encl->segment_tbl[] check succeeds.
