We have to check if the values are >= *_MAX, not just >, fix it. From the bugzilla report: ''In file /tools/perf/util/evsel.c function __perf_evsel__hw_cache_name it appears that there is a bug that reads beyond the end of the buffer. The statement "if (type > PERF_COUNT_HW_CACHE_MAX)" allows type to be equal to the maximum value. Later, when statement "if (!perf_evsel__is_cache_op_valid(type, op))" is executed, the function can access array perf_evsel__hw_cache_stat[type] beyond the end of the buffer. It appears to me that the statement "if (type > PERF_COUNT_HW_CACHE_MAX)" should be "if (type >= PERF_COUNT_HW_CACHE_MAX)" Bug found with Coverity and manual code review. No attempts were made to execute the code with a maximum type value.''

The problem is uClibc also defines __GLIBC__ for exported headers for applications. So add that specific check to not trip for uClibc.

In order to successfully decode Intel PT traces, context switch events are needed from the moment the trace starts. Currently that is ensured by using the 'immediate' flag which enables the switch event when it is opened. However, since commit 86c27869 ("perf intel-pt: Add support for PERF_RECORD_SWITCH") that might not always happen. When tracing system-wide the context switch event is added to the tracking event which was not set as 'immediate'. Change that so it is.

Commit 73cdf0c6 ("perf symbols: Record text offset in dso to calculate objdump address") started storing the offset of the text section for all DSOs: if (elf_section_by_name(elf, &ehdr, &tshdr, ".text", NULL)) dso->text_offset = tshdr.sh_addr - tshdr.sh_offset; Unfortunately this breaks debuginfo files, because we need to calculate the offset of the text section in the associated executable file. As a result perf annotate returns junk for all debuginfo files. Fix this by using runtime_ss->elf which should point at the executable when parsing a debuginfo file.

Pull power management fixes from Rafael Wysocki: "Two hibernation fixes allowing it to work with the recently added randomization of the kernel identity mapping base on x86-64 and one cpufreq driver regression fix. Specifics: - Fix the x86 identity mapping creation helpers to avoid the assumption that the base address of the mapping will always be aligned at the PGD level, as it may be aligned at the PUD level if address space randomization is enabled (Rafael Wysocki). - Fix the hibernation core to avoid executing tracing functions before restoring the processor state completely during resume (Thomas Garnier). - Fix a recently introduced regression in the powernv cpufreq driver that causes it to crash due to an out-of-bounds array access (Akshay Adiga)" * tag 'pm-4.8-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: PM / hibernate: Restore processor state before using per-CPU variables x86/power/64: Always create temporary identity mapping correctly cpufreq: powernv: Fix crash in gpstate_timer_handler()

Restore the processor state before calling any other functions to ensure per-CPU variables can be used with KASLR memory randomization. Tracing functions use per-CPU variables (GS based on x86) and one was called just before restoring the processor state fully. It resulted in a double fault when both the tracing & the exception handler functions tried to use a per-CPU variable.

nfsd4_lock will take the st_mutex before working with the stateid it gets, but between the time when we drop the cl_lock and take the mutex, the stateid could become unhashed (a'la FREE_STATEID). If that happens the lock stateid returned to the client will be forgotten. Fix this by first moving the st_mutex acquisition into lookup_or_create_lock_state. Then, have it check to see if the lock stateid is still hashed after taking the mutex. If it's not, then put the stateid and try the find/create again.

Pull libnvdimm fixes from Dan Williams: - Fix for the nd_blk (NVDIMM Block Window Aperture) driver. A spec clarification requires the driver to mask off reserved bits in status register. This is tagged for -stable back to the v4.2 kernel. - Fix for a kernel crash in the nvdimm unit tests when module loading is interrupted with SIGTERM. Tagged for -stable since validation efforts external to Intel use the unit tests for qualifying backports. - Add a new 'size' sysfs attribute for the BTT (NVDIMM Block Translation Table) driver to make it symmetric with the other namespace personality drivers (PFN and DAX) that provide a size attribute for indicating how much namespace capacity is lost to metadata. The BTT change arrived at the start of the merge window and has appeared in a -next release. It can technically wait for 4.9, but it is small, fixes asymmetry in the libnvdimm-sysfs interface, and something I would have squeezed into the v4.8 pull request had it arrived a few days earlier. * 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: tools/testing/nvdimm: fix SIGTERM vs hotplug crash nvdimm, btt: add a size attribute for BTTs libnvdimm, nd_blk: mask off reserved status bits
