* perf tools: Fix GNU-only grep usage in MakefileJohn Spencer2014-09-171-1/+1

* perf tools: Disable kernel symbol demangling by defaultAvi Kivity2014-09-179-1/+23
| | | | | | | | | | | | | | | Some Linux symbols (for example __vt_event_wait) are interpreted by the demangler as C++ mangled names, which of course they aren't. Disable kernel symbol demangling by default to avoid this, and allow enabling it with a new option --demangle-kernel for those who wish it.

* perf tools: Let default config be defined for a PMUAdrian Hunter2014-09-174-19/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows default config terms to be provided for a PMU. So, for example, when the Intel PT PMU is added, it will be possible to specify: intel_pt// which will be the same as: intel_pt/tsc=1,noretcomp=0/ meaning that the trace should contain TSC timestamps and perform 'return compression'. An important consideration of this patch is that it must be possible to overwrite the default values. That has meant changing the logic so that a zero value can replace a non-zero value.

* perf tools: Add perf-with-kcore scriptAdrian Hunter2014-09-173-1/+264
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Decoding an Intel PT trace of the kernel requires an accurate kernel object image. This is provided by making a copy of kcore. However the copy needs to be made under the same conditions as the original recording, and then it needs to be associated with the perf.data file. The perf-with-kcore script does that. The script also checks the permissions on the buildid cache and can be used to fix them. That is needed for distributions where root does not have a home directory and consequently writes to the same buildid cache as the user, resulting in cached files that the user does not have access to. Example: $ ./perf-with-kcore Usage: perf-with-kcore <perf sub-command> <perf.data directory> [<sub-command options> [ -- <workload>]] <perf sub-command> can be record, script, report or inject or: perf-with-kcore fix_buildid_cache_permissions $ ./perf-with-kcore record pt_uname -e intel_pt// -- uname Recording Using /home/ahunter/bin/perf perf version 3.15.rc3.g4549ba /home/ahunter/bin/perf record -o pt_uname/perf.data -e intel_pt// -- uname Linux [ perf record: Woken up 3 times to write data ] [ perf record: Captured and wrote 0.023 MB pt_uname/perf.data ] Copying kcore [sudo] password for ahunter: Done $ tools/perf/perf-with-kcore.sh script pt_uname | head Using /home/ahunter/bin/perf perf version 3.15.rc3.g4549ba /home/ahunter/bin/perf script -i pt_uname/perf.data --kallsyms=pt_uname/kcore_dir/kallsyms swapper 0 [002] 161533.969666: sched:sched_switch: swapper/2:0 [120] R ==> perf:11316 [120] :11315 11315 [003] 161533.969704: sched:sched_switch: perf:11315 [120] S ==> swapper/3:0 [120] :11316 11316 [002] 161533.969783: sched:sched_switch: perf:11316 [120] R ==> migration/2:33 [0] :33 33 [002] 161533.969791: sched:sched_switch: migration/2:33 [0] S ==> swapper/2:0 [120] swapper 0 [003] 161533.969792: sched:sched_switch: swapper/3:0 [120] R ==> perf:11316 [120] :11316 11316 [003] 161533.970062: branches: 0 [unknown] ([unknown]) => ffffffff810532fa native_write_msr_safe ([kernel.kallsyms]) :11316 11316 [003] 161533.970062: branches: ffffffff810532fd native_write_msr_safe ([kernel.kallsyms]) => ffffffff81035b31 pt_config_start ([kernel.kallsyms]) Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Namhyung Kim <namhyung@gmail.com> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Stephane Eranian <eranian@google.com> Link: http://lkml.kernel.org/r/1406786474-9306-30-git-send-email-adrian.hunter@intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
* perf tools: Let a user specify a PMU event without any config termsAdrian Hunter2014-09-172-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This enables a PMU event to be specified in the form: pmu// which is effectively the same as: pmu/config=0/ This patch is a precursor to defining default config for a PMU. Further explanation extracted from lkml thread: Imagine that the 'tsc' term did not exist. Intel PT trace data would not contain TSC packets, and the decoder would not know how to decode them. Then imagine that a new version of the hardware adds 'tsc'. It is such a useful feature that we want it by default, but older versions of the tools don't know how to decode it, so the kernel cannot turn it on by default. It is similar to why the kernel does not select perf_event_attr.mmap2 by default. The kernel doesn't know whether the tool supports it.

The most significant change for users is the first patch which makes setns drmatically faster by removing unneded rcu handling. The next chunk of changes are so that "mount -o remount,.." will not allow the user namespace root to drop flags on a mount set by the system wide root. Aks this forces read-only mounts to stay read-only, no-dev mounts to stay no-dev, no-suid mounts to stay no-suid, no-exec mounts to stay no exec and it prevents unprivileged users from messing with a mounts atime settings. I have included my test case as the last patch in this series so people performing backports can verify this change works correctly. The next change fixes a bug in NFS that was discovered while auditing nsproxy users for the first optimization. Today you can oops the kernel by reading /proc/fs/nfsfs/{servers,volumes} if you are clever with pid namespaces. I rebased and fixed the build of the !CONFIG_NFS_FS case yesterday when a build bot caught my typo. Given that no one to my knowledge bases anything on my tree fixing the typo in place seems more responsible that requiring a typo-fix to be backported as well. The last change is a small semantic cleanup introducing /proc/thread-self and pointing /proc/mounts and /proc/net at it. This prevents several kinds of problemantic corner cases. It is a user-visible change so it has a minute chance of causing regressions so the change to /proc/mounts and /proc/net are individual one line commits that can be trivially reverted. Unfortunately I lost and could not find the email of the original reporter so he is not credited.

| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Kenton Varda <kenton@sandstorm.io> discovered that by remounting a read-only bind mount read-only in a user namespace the MNT_LOCK_READONLY bit would be cleared, allowing an unprivileged user to the remount a read-only mount read-write. Upon review of the code in remount it was discovered that the code allowed nosuid, noexec, and nodev to be cleared. It was also discovered that the code was allowing the per mount atime flags to be changed. The first naive patch to fix these issues contained the flaw that using default atime settings when remounting a filesystem could be disallowed. To avoid this problems in the future add tests to ensure unprivileged remounts are succeeding and failing at the appropriate times. Cc: stable@vger.kernel.org Acked-by: Serge E.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On IBM powerpc where multiple page size value are supported, current ppc64 and ppc64el distro don't define the PAGE_SIZE variable in /usr/include as this is a dynamic value retrieved by the getpagesize() or sysconf() defined in unistd.h. The PAGE_SIZE variable sounds defined when only one value is supported by the kernel. As such, when the PAGE_SIZE definition doesn't exist system should retrieve the dynamic value.

The short story: The biggest bit is Michael removing all of pre-POWER4 processor support from the 64-bit kernel. POWER3 and rs64. This gets rid of a ton of old cruft that has been bitrotting in a long while. It was broken for quite a few versions already and nobody noticed. Nobody uses those machines anymore. While at it, he cleaned up a bunch of old dusty cabinets, getting rid of a skeletton or two. Then, we have some base VFIO support for KVM, which allows assigning of PCI devices to KVM guests, support for large 64-bit BARs on "powernv" platforms, support for HMI (Hardware Management Interrupts) on those same platforms, some sparse-vmemmap improvements (for memory hotplug), There is the usual batch of Freescale embedded updates (summary in the merge commit) and fixes here or there, I think that's it for the highlights" * 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: (102 commits) powerpc/eeh: Export eeh_iommu_group_to_pe() powerpc/eeh: Add missing #ifdef CONFIG_IOMMU_API powerpc: Reduce scariness of interrupt frames in stack traces powerpc: start loop at section start of start in vmemmap_populated() powerpc: implement vmemmap_free() powerpc: implement vmemmap_remove_mapping() for BOOK3S powerpc: implement vmemmap_list_free() powerpc: Fail remap_4k_pfn() if PFN doesn't fit inside PTE powerpc/book3s: Fix endianess issue for HMI handling on napping cpus. powerpc/book3s: handle HMIs for cpus in nap mode. powerpc/powernv: Invoke opal call to handle hmi. powerpc/book3s: Add basic infrastructure to handle HMI in Linux. powerpc/iommu: Fix comments with it_page_shift powerpc/powernv: Handle compound PE in config accessors powerpc/powernv: Handle compound PE for EEH powerpc/powernv: Handle compound PE powerpc/powernv: Split ioda_eeh_get_state() powerpc/powernv: Allow to freeze PE powerpc/powernv: Enable M64 aperatus for PHB3 powerpc/eeh: Aux PE data for error log ...

We inherited that from the top-level selftests Makefile which aims to build and run as many tests as possible and damn the torpedoes. For the powerpc tests we'd instead like any errors to fail the build, so we can automatically catch build failures. We can achieve the best of both worlds by using -k, which tells make to keep building when it hits an error, but still reports the error.

From the new code perspective, the ACPICA update brings ACPI 5.1 to the table, including a new device configuration object called _DSD (Device Specific Data) that will hopefully help us to operate device properties like Device Trees do (at least to some extent) and changes related to supporting ACPI on ARM. Apart from that we have hibernation changes making it use radix trees to store memory bitmaps which should speed up some operations carried out by it quite significantly. We also have some power management changes related to suspend-to-idle (the "freeze" sleep state) support and more preliminary changes needed to support ACPI on ARM (outside of ACPICA). The rest is fixes and cleanups pretty much everywhere. Specifics: - ACPICA update to upstream version 20140724. That includes ACPI 5.1 material (support for the _CCA and _DSD predefined names, changes related to the DMAR and PCCT tables and ARM support among other things) and cleanups related to using ACPICA's header files. A major part of it is related to acpidump and the core code used by that utility. Changes from Bob Moore, David E Box, Lv Zheng, Sascha Wildner, Tomasz Nowicki, Hanjun Guo. - Radix trees for memory bitmaps used by the hibernation core from Joerg Roedel. - Support for waking up the system from suspend-to-idle (also known as the "freeze" sleep state) using ACPI-based PCI wakeup signaling (Rafael J Wysocki). - Fixes for issues related to ACPI button events (Rafael J Wysocki). - New device ID for an ACPI-enumerated device included into the Wildcat Point PCH from Jie Yang. - ACPI video updates related to backlight handling from Hans de Goede and Linus Torvalds. - Preliminary changes needed to support ACPI on ARM from Hanjun Guo and Graeme Gregory. - ACPI PNP core cleanups from Arjun Sreedharan and Zhang Rui. - Cleanups related to ACPI_COMPANION() and ACPI_HANDLE() macros (Rafael J Wysocki). - ACPI-based device hotplug cleanups from Wei Yongjun and Rafael J Wysocki. - Cleanups and improvements related to system suspend from Lan Tianyu, Randy Dunlap and Rafael J Wysocki. - ACPI battery cleanup from Wei Yongjun. - cpufreq core fixes from Viresh Kumar. - Elimination of a deadband effect from the cpufreq ondemand governor and intel_pstate driver cleanups from Stratos Karafotis. - 350MHz CPU support for the powernow-k6 cpufreq driver from Mikulas Patocka. - Fix for the imx6 cpufreq driver from Anson Huang. - cpuidle core and governor cleanups from Daniel Lezcano, Sandeep Tripathy and Mohammad Merajul Islam Molla. - Build fix for the big_little cpuidle driver from Sachin Kamat. - Configuration fix for the Operation Performance Points (OPP) framework from Mark Brown. - APM cleanup from Jean Delvare. - cpupower utility fixes and cleanups from Peter Senna Tschudin, Andrey Utkin, Himangi Saraogi, Rickard Strandqvist, Thomas Renninger" * tag 'pm+acpi-3.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (118 commits) ACPI / LPSS: add LPSS device for Wildcat Point PCH ACPI / PNP: Replace faulty is_hex_digit() by isxdigit() ACPICA: Update version to 20140724.
