c9b0888 Peter Zijlstra 03 February 2014, 13:29:03 UTC perf/x86: Correctly use FEATURE_PDCM The current code simply assumes Intel Arch PerfMon v2+ to have the IA32_PERF_CAPABILITIES MSR; the SDM specifies that we should check CPUID[1].ECX[15] (aka, FEATURE_PDCM) instead. This was found by KVM which implements v2+ but didn't provide the capabilities MSR. Change the code to DTRT; KVM will also implement the MSR and return 0.

6a02652 Francesco Fusco 27 January 2014, 13:39:13 UTC perf tools: Fix include for non x86 architectures Commit 71ae8aac ("lib: introduce arch optimized hash library") added an include to <linux/hash.h> for setting up an architecture specific fast hash. Since perf includes directly the non-uapi kernel header, it cannot find <asm/hash.h> on non-x86 and thus prevents perf to be compiled on every architecture other than x86. The problem is the inclusion of <asm/hash.h> in hash.h that results in the following error originating from util/evlist.c: fatal error: asm/hash.h: No such file or directory This commit simply adds an empty <asm/hash.h> stub/file to fix the compile issue on non-x86 architectures. As perf does not use any of these new functions, it fixes the compilation and therefore seems to be the most appropriate solution to go with.

b935a58 Josh Boyer 22 January 2014, 15:01:48 UTC perf tools: Fix traceevent plugin path definitions The plugindir_SQ definition contains $(prefix) which is not needed as the $(libdir) definition already contains prefix in it. This leads to the path including an extra prefix in it, e.g. /usr/usr/lib64. The -DPLUGIN_DIR defintion includes DESTDIR. This is incorrect, as it sets the plugin search path to include the value of DESTDIR. DESTDIR is a mechanism to install in a non-standard location such as a chroot or an RPM build root. In the RPM case, this leads to the search path being incorrect after the resulting RPM is installed (or in some cases an RPM build failure). Remove both of these unnecessary inclusions.

8ad9219 Stephane Eranian 17 January 2014, 15:34:06 UTC perf stat: Fix memory corruption of xyarray when cpumask is used This patch fixes a memory corruption problem with the xyarray when the evsel fds get closed at the end of the run_perf_stat() call. It could be triggered with: # perf stat -a -e power/energy-cores/ ls When cpumask are used by events (.e.g, RAPL or uncores) then the evsel fds are allocated based on the actual number of CPUs monitored. That number can be smaller than the total number of CPUs on the system. The problem arises at the end by perf stat closes the fds twice. When fds are closed, their entry in the xyarray are set to -1. The first close() on the evsel is made from __run_perf_stat() and it uses the actual number of CPUS for the event which is how the xyarray was allocated for. The second is from perf_evlist_close() but that one is on the total number of CPUs in the system, so it assume the xyarray was allocated to cover it. However it was not, and some writes corrupt memory. The fix is in perf_evlist_close() is to first try with the evsel->cpus if present, if not use the evlist->cpus. That fixes the problem.

961d9ca Steven Rostedt (Red Hat) 19 January 2014, 00:52:13 UTC ktest: Add BISECT_TRIES to bisect test For those cases that it takes several tries to hit a bug, it would be useful for ktest.pl to try a test multiple times before it considers the test as a pass. To accomplish this, BISECT_TRIES ktest config option has been added. It is default to one, as most of the time a bisect only needs to try a test once. But the user can now up this to make ktest run a given test multiple times. The first failure that is detected will set a bisect bad. It only repeats on success. Note, as with all race bugs, there's no guarantee that if it succeeds, it is really a good bisect. But it helps in case the bug is somewhat reliable. You can set BISECT_TRIES to zero, and all tests will be considered good, unless you also set BISECT_MANUAL. Suggested-by: "Paul E.

3af57f7 Heiko Carstens 17 January 2014, 08:37:15 UTC s390/bpf,jit: fix 32 bit divisions, use unsigned divide instructions The s390 bpf jit compiler emits the signed divide instructions "dr" and "d" for unsigned divisions. This can cause problems: the dividend will be zero extended to a 64 bit value and the divisor is the 32 bit signed value as specified A or X accumulator, even though A and X are supposed to be treated as unsigned values. The divide instrunctions will generate an exception if the result cannot be expressed with a 32 bit signed value. This is the case if e.g. the dividend is 0xffffffff and the divisor either 1 or also 0xffffffff (signed: -1). To avoid all these issues simply use unsigned divide instructions.

Additionally this code now has a race condition. Replace it with a much simpler variant, which just scans the address list when duplicate address detection completes, to check if this is the first valid link local address and send RS and MLD reports then.

77f99ad Christoph Paasch 16 January 2014, 19:01:21 UTC tcp: metrics: Avoid duplicate entries with the same destination-IP Because the tcp-metrics is an RCU-list, it may be that two soft-interrupts are inside __tcp_get_metrics() for the same destination-IP at the same time. If this destination-IP is not yet part of the tcp-metrics, both soft-interrupts will end up in tcpm_new and create a new entry for this IP. So, we will have two tcp-metrics with the same destination-IP in the list. This patch checks twice __tcp_get_metrics(). First without holding the lock, then while holding the lock. The second one is there to confirm that the entry has not been added by another soft-irq while waiting for the spin-lock. Fixes: 51c5d0c4b169b (tcp: Maintain dynamic metrics in local cache.)

The prepend_path, d_path, d_absolute_path, and __d_path family of functions is a really mess. Me: Yes, patching d_path is really sufficient. Yes, the code is mess.

b965bb4 Frederic Weisbecker 14 January 2014, 15:37:15 UTC perf callchain: Spare double comparison of callchain first entry When a new callchain child branch matches an existing one in the rbtree, the comparison of its first entry is performed twice: 1) From append_chain_children() on branch lookup 2) If 1) reports a match, append_chain() then compares all entries of the new branch against the matching node in the rbtree, and this comparison includes the first entry of the new branch again. Lets shortcut this by performing the whole comparison only from append_chain() which then returns the result of the comparison between the first entry of the new branch and the iterating node in the rbtree. If the first entry matches, the lookup on the current level of siblings stops and propagates to the children of the matching nodes. This results in less comparisons performed by the CPU.
