through PERF_RECORD_ID\nbecause each inherited counter gets its own id.\n\nHis suggestion was to always return the parent counter id, since that\nis the primary counter id as exposed. However, these inherited\ncounters have a unique identifier so that events like\nPERF_EVENT_PERIOD and PERF_EVENT_THROTTLE can be specific about which\ncounter gets modified, which is important when trying to normalize the\nsample streams.\n\nThis patch removes PERF_EVENT_PERIOD in favour of PERF_SAMPLE_PERIOD,\nwhich is more useful anyway, since changing periods became a lot more\ncommon than initially thought -- rendering PERF_EVENT_PERIOD the less\nuseful solution (also, PERF_SAMPLE_PERIOD reports the more accurate\nvalue, since it reports the value used to trigger the overflow,\nwhereas PERF_EVENT_PERIOD simply reports the requested period changed,\nwhich might only take effect on the next cycle).\n\nThis still leaves us PERF_EVENT_THROTTLE to consider, but since that\n_should_ be a rare occurrence, and linking it to a primary id is the\nmost useful bit to diagnose the problem, we introduce a\nPERF_SAMPLE_STREAM_ID, for those few cases where the full\nreconstruction is important.\n\n[Does change the ABI a little, but I see no other way out]\n\nSuggested-by: Anton Blanchard \u003canton@samba.org\u003e\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nLKML-Reference: \u003c1248095846.15751.8781.camel@twins\u003e\n" }, { "commit": "573402db02746179b3f95f83a11a787501f52d0a", "tree": "111fb9d0b65d31cb9308a84164f111874d2522ae", "parents": [ "c9f73a3dd27e03411f18a58c0814d51392d2b17a" ], "author": { "name": "Peter Zijlstra", "email": "a.p.zijlstra@chello.nl", "time": "Wed Jul 22 11:13:50 2009 +0200" }, "committer": { "name": "Peter Zijlstra", "email": "a.p.zijlstra@chello.nl", "time": "Wed Jul 22 18:05:55 2009 +0200" }, "message": "perf_counter: Plug more stack leaks\n\nPer example of Arjan\u0027s patch, I went through and found a few more.\n\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\n" }, { "commit": "c9f73a3dd27e03411f18a58c0814d51392d2b17a", "tree": "2b687a70433efc77f3f890bd5f09d31414d26f8e", "parents": [ "9b7019ae6a542a801a80df6694c66e240e2c3e39" ], "author": { "name": "Arjan van de Ven", "email": "arjan@linux.intel.com", "time": "Tue Jul 21 00:55:05 2009 -0700" }, "committer": { "name": "Peter Zijlstra", "email": "a.p.zijlstra@chello.nl", "time": "Wed Jul 22 18:05:55 2009 +0200" }, "message": "perf: Fix stack data leak\n\nthe \"reserved\" field was not initialized to zero, resulting in 4 bytes\nof stack data leaking to userspace....\n\nSigned-off-by: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\n" }, { "commit": "1d2f37945d1b3a14086c5ea802486778b635cf97", "tree": "b40a1a596a29acc1511f661c27f284dd06b0bc9d", "parents": [ "1483b19f8f5e8ad0c8816de368b099322dad4db5", "f1c6a58121f9846ac665b0fbd3cbab90ce8bcbac" ], "author": { "name": "Peter Zijlstra", "email": "a.p.zijlstra@chello.nl", "time": "Wed Jul 22 18:05:48 2009 +0200" }, "committer": { "name": "Peter Zijlstra", "email": "a.p.zijlstra@chello.nl", "time": "Wed Jul 22 18:05:48 2009 +0200" }, "message": "Merge commit \u0027tip/perfcounters/core\u0027 into perf-counters-for-linus\n" }, { "commit": "9ba5f005c994ad28e266a0cd14ef29354be382c9", "tree": "0a2ff570070afc18e7dad61a2955b94614ce9b51", "parents": [ "aea1f7964ae6cba5eb419a958956deb9016b3341" ], "author": { "name": "Peter Zijlstra", "email": "peterz@infradead.org", "time": "Wed Jul 22 14:18:35 2009 +0200" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Wed Jul 22 17:01:17 2009 +0200" }, "message": "softirq: introduce tasklet_hrtimer infrastructure\n\ncommit ca109491f (hrtimer: removing all ur callback modes) moved all\nhrtimer callbacks into hard interrupt context when high resolution\ntimers are active.

Migrating the timer might delay it because\nwe can not reprogram the clock event device on the other CPU. But the\ncode implementing that check has two flaws:\n\n- for !HIGHRES the check compares the expiry value with the clock\n events device expiry value which is wrong for CLOCK_REALTIME based\n timers.\n\n- the check is racy. It holds the hrtimer base lock of the target CPU,\n but the clock event device expiry value can be modified\n nevertheless, e.g. by an timer interrupt firing.\n\nThe !HIGHRES case is easy to fix as we can enqueue the timer on the\ncpu which was selected by the load balancer. It runs the idle\nbalancing code once per jiffy anyway. So the maximum delay for the\ntimer is the same as when we keep the tick on the current cpu going.\n\nIn the HIGHRES case we can get the next expiry value from the hrtimer\ncpu_base of the target CPU and serialize the update with the cpu_base\nlock. This moves the lock section in hrtimer_interrupt() so we can set\nnext_event to KTIME_MAX while we are handling the expired timers and\nset it to the next expiry value after we handled the timers under the\nbase lock. While the expired timers are processed timer migration is\nblocked because the expiry time of the timer is always \u003c\u003d KTIME_MAX.\n\nAlso remove the now useless clockevents_get_next_event() function.\n\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n" }, { "commit": "7e0c5086c172ecf8b0c2ad860b02a586967d17d0", "tree": "207e1975ea970279e5ad912a094361e2fa169d93", "parents": [ "507e123151149e578c9aae33eb876c49824da5f8" ], "author": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Thu Jul 09 13:52:32 2009 +0200" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Fri Jul 10 17:22:20 2009 +0200" }, "message": "hrtimer: migration: do not check expiry time on current CPU\n\nThe timer migration code needs to check whether the expiry time of the\ntimer is before the programmed clock event expiry time when the timer\nis enqueued on another CPU because we can not reprogram the timer\ndevice on the other CPU.

write\naccess faults.\n\nThe patch was made on two wrong assumptions:\n\n1) access_ok(VERIFY_WRITE,...) would actually check write access.\n\n On x86 it does _NOT_. It\u0027s a pure address range check.\n\n2) a RW mapped region can not go away under us.\n\n That\u0027s wrong as well. Nobody can prevent another thread to call\n mprotect(PROT_READ) on that region where the futex resides. If that\n call hits between the get_user_pages_fast() verification and the\n actual write access in the atomic region we are toast again.\n\nThe solution is to not rely on access_ok and get_user() for any write\naccess related fault on private and shared futexes. Instead we need to\nfault it in with verification of write access.\n\nThere is no generic non destructive write mechanism which would fault\nthe user page in trough a #PF, but as we already know that we will\nfault we can as well call get_user_pages() directly and avoid the #PF\noverhead.\n\nIf get_user_pages() returns -EFAULT we know that we can not fix it\nanymore and need to bail out to user space.\n\nRemove a bunch of confusing comments on this issue as well.\n\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: stable@kernel.org\n" }, { "commit": "f6faac71d502be1c29c81b2f45657662c3b84470", "tree": "b320a04b6f3955c60edaa30f47b889a0daf9f4b6", "parents": [ "4e8a2372f9255a1464ef488ed925455f53fbdaa1" ], "author": { "name": "Paul E.
