The returning\ntask returns to user space with ETIMEOUT or EINTR, but the user space\nfutex value is assigned to this task. The task which acquired the\nrt_mutex fixes the user space futex value right after the hash bucket\nlock has been released by the returning task, but for a short period of\ntime the user space value is wrong.\n\nDetailed description is available at:\n\n https://bugzilla.redhat.com/show_bug.cgi?id\u003d400541\n\nThe fix for this is the same as we do when the rt_mutex was acquired by\na higher priority task via lock stealing from the designated new owner.\nIn that case we already fix the user space value and the internal\npi_state up before we return. This mechanism can be used to fixup the\nabove corner case as well. When the returning task, which failed to\nacquire the rt_mutex, notices that it is the designated owner of the\nfutex, then it fixes up the stale user space value and the pi_state,\nbefore returning to user space. This happens with the futex hash bucket\nlock held, so the task which acquired the rt_mutex is guaranteed to be\nblocked on the hash bucket lock. We can access the rt_mutex owner, which\ngives us the pid of the new owner, safely here as the owner is not able\nto modify (release) it while waiting on the hash bucket lock.\n\nRename the \"curr\" argument of fixup_pi_state_owner() to \"newowner\" to\navoid confusion with current and add the check for the stale state into\nthe failure path of rt_mutex_trylock() in the return path of\nunlock_futex_pi(). If the situation is detected use\nfixup_pi_state_owner() to assign everything to the owner of the\nrt_mutex.\n\nPointed-out-and-tested-by: Roland Westrelin \u003croland.westrelin@sun.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "83a08e7c6ed533a47631794e7f618a98094b4129", "tree": "cf3246a639fc66b4a81968c78edad33598729029", "parents": [ "caeeeecfdaeada2998eb3c29c3ebd59afb79ef06" ], "author": { "name": "Ken\u0027ichi Ohmichi", "email": "oomichi@mxs.nes.nec.co.jp", "time": "Tue Jan 08 15:33:05 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Jan 08 16:10:36 2008 -0800" }, "message": "vmcoreinfo: add the array length of \"free_list\" for filtering free pages\n\nThis patch adds the array length of \"free_area.free_list\" to the vmcoreinfo\ndata so that makedumpfile (dump filtering command) can exclude all free pages\nin linux-2.6.24.\n\nmakedumpfile creates a small dumpfile by excluding unnecessary pages for the\nanalysis.

But the issue\nthat was uncovered was that the simple handler should never mask.\n\nThis patch reverts the masking in the simple handler.\n\nSigned-off-by: Steven Rostedt \u003csrostedt@redhat.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nAcked-by: Russell King \u003crmk+kernel@arm.linux.org.uk\u003e\n" }, { "commit": "b4be625852618636a6b54908c4f9d90fb29dc549", "tree": "87c8f5f83b059ab839ce11dcc5e17f5fb12b0723", "parents": [ "b019e57321f3e006c0ec7a54f13efc377bcb6451" ], "author": { "name": "Adrian Bunk", "email": "bunk@kernel.org", "time": "Tue Dec 18 18:05:58 2007 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Tue Dec 18 18:05:58 2007 +0100" }, "message": "timer: kernel/timer.c section fixes\n\nThis patch fixes the following section mismatches with CONFIG_HOTPLUG\u003dn,\nCONFIG_HOTPLUG_CPU\u003dy:\n\n...\nWARNING: vmlinux.o(.text+0x41cd3): Section mismatch: reference to .init.data:tvec_base_done.22610 (between \u0027timer_cpu_notify\u0027 and \u0027run_timer_softirq\u0027)\nWARNING: vmlinux.o(.text+0x41d67): Section mismatch: reference to .init.data:tvec_base_done.22610 (between \u0027timer_cpu_notify\u0027 and \u0027run_timer_softirq\u0027)\n...\n\nSigned-off-by: Adrian Bunk \u003cbunk@kernel.org\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n" }, { "commit": "cdc6f27d9e3c2f7ca1a3e19c6eabb1ad6a2add5d", "tree": "d557b594cd5d180e1ce91cac25a29d81a42499a5", "parents": [ "bd87f1f028ddaad45d4a9a3621dfe688c840ba41" ], "author": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Tue Dec 18 18:05:58 2007 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Tue Dec 18 18:05:58 2007 +0100" }, "message": "clockevents: fix reprogramming decision in oneshot broadcast\n\nResolve the following regression of a choppy, almost unusable laptop:\n\n http://lkml.org/lkml/2007/12/7/299\n http://bugzilla.kernel.org/show_bug.cgi?id\u003d9525\n\nA previous version of the code did the reprogramming of the broadcast\ndevice in the return from idle code.

However, with\na boolean global value and per-mount quota enforcement constraining the\ndynamic pool, adding corresponding control of the dynamic pool on a\nper-node basis seems inconsistent to me.\n\n2) Administration of the hugetlb dynamic pool with multiple hugetlbfs\nmount points is, arguably, more arduous than it needs to be. Each quota\nwould need to be set separately, and the sum would need to be monitored.\n\nTo ease the administration, and to help make the way for per-node\ncontrol of the static \u0026 dynamic hugepage pool, I added a separate\nsysctl, nr_overcommit_hugepages. This value serves as a high watermark\nfor the overall hugepage pool, while nr_hugepages serves as a low\nwatermark. The boolean sysctl can then be removed, as the condition\n\n\tnr_overcommit_hugepages \u003e 0\n\nindicates the same administrative setting as\n\n\thugetlb_dynamic_pool \u003d\u003d 1\n\nQuotas still serve as local enforcement of the size of the pool on a\nper-mount basis.\n\nA few caveats:\n\n1) There is a race whereby the global surplus huge page counter is\nincremented before a hugepage has allocated. Another process could then\ntry grow the pool, and fail to convert a surplus huge page to a normal\nhuge page and instead allocate a fresh huge page. I believe this is\nbenign, as no memory is leaked (the actual pages are still tracked\ncorrectly) and the counters won\u0027t go out of sync.\n\n2) Shrinking the static pool while a surplus is in effect will allow the\nnumber of surplus huge pages to exceed the overcommit value. As long as\nthis condition holds, however, no more surplus huge pages will be\nallowed on the system until one of the two sysctls are increased\nsufficiently, or the surplus huge pages go out of use and are freed.\n\nSuccessfully tested on x86_64 with the current libhugetlbfs snapshot,\nmodified to use the new sysctl.\n\nSigned-off-by: Nishanth Aravamudan \u003cnacc@us.ibm.com\u003e\nAcked-by: Adam Litke \u003cagl@us.ibm.com\u003e\nCc: William Lee Irwin III \u003cwli@holomorphy.com\u003e\nCc: Dave Hansen \u003chaveblue@us.ibm.com\u003e\nCc: David Gibson \u003cdavid@gibson.dropbear.id.au\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "2c5ea0f2d8c7d4883dd0d8ec3c7e3f3640b4f814", "tree": "f6412441325195c16351822cff8da5f2ed5f1cfe", "parents": [ "fa2dd441df28b9fdfc68f84ae66f1b507cfff0e4", "e17bcb43a26a7111f851b5ff6d1258ecd355de75" ], "author": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Fri Dec 07 11:01:26 2007 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Fri Dec 07 11:01:26 2007 -0800" }, "message": "Merge git://git.kernel.org/pub/scm/linux/kernel/git/x86/linux-2.6-x86\n\n* git://git.kernel.org/pub/scm/linux/kernel/git/x86/linux-2.6-x86:\n ACPI: move timer broadcast before busmaster disable\n clockevents: warn once when program_event() is called with negative expiry\n hrtimers: avoid overflow for large relative timeouts\n" }, { "commit": "167b1de3ee4e50d65a2bd0a2667c9cd48faf54f3", "tree": "f1bdad90f0bb39fcaa9b2d6eed12fe2a0bb9d48e", "parents": [ "62f0f61e6673e67151a7c8c0f9a09c7ea43fe2b5" ], "author": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Fri Dec 07 19:16:17 2007 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Dec 07 19:16:17 2007 +0100" }, "message": "clockevents: warn once when program_event() is called with negative expiry\n\nThe hrtimer problem with large relative timeouts resulting in a\nnegative expiry time went unnoticed as there is no check in the\nclockevents_program_event() code.

This code does not return\nback to userspace, so we set up a RESTARTBLOCK. The bug here is that we\nsave the \"abs_time\" which is a pointer to the stack variable \"ktime_t t\"\nfrom sys_futex.\n\nThis returns and unwinds the stack before we get to call our signal. On\nreturn from the signal we go to futex_wait_restart, where we update all\nthe parameters for futex_wait and call it. But here we have a problem\nwhere abs_time is no longer valid.\n\nI verified this with print statements, and sure enough, what abs_time\nwas set to ends up being garbage when we get to futex_wait_restart.\n\nThe solution I did to solve this (with input from Linus Torvalds)\nwas to add unions to the restart_block to allow system calls to\nuse the restart with specific parameters. This way the futex code now\nsaves the time in a 64bit value in the restart block instead of storing\nit on the stack.\n\nNote: I\u0027m a bit nervious to add \"linux/types.h\" and use u32 and u64\nin thread_info.h, when there\u0027s a #ifdef __KERNEL__ just below that.\nNot sure what that is there for. If this turns out to be a problem, I\u0027ve\ntested this with using \"unsigned int\" for u32 and \"unsigned long long\" for\nu64 and it worked just the same. I\u0027m using u32 and u64 just to be\nconsistent with what the futex code uses.\n\nSigned-off-by: Steven Rostedt \u003csrostedt@redhat.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nAcked-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "874a5f87f53f80b798140b07fcf81f8d3718b3cc", "tree": "4142862ffba59ecfc2a76c7ce3e185a42d871e04", "parents": [ "6fab2600f9eae779ac49416e651a7f160004c9ae" ], "author": { "name": "David S.

This feature would be\nuseful if someone wants to group tasks only for accounting purpose and doesnt\nreally want to exercise any control over their cpu consumption.\n\nThe patch below reintroduces the feature. It is based on Paul Menage\u0027s\noriginal patch (Commit 62d0df64065e7c135d0002f069444fbdfc64768f), with\nthese differences:\n\n - Removed load average information. I felt it needs more thought (esp\n\t to deal with SMP and virtualized platforms) and can be added for\n\t 2.6.25 after more discussions.\n - Convert group cpu usage to be nanosecond accurate (as rest of the cfs\n\t stats are) and invoke cpuacct_charge() from the respective scheduler\n\t classes\n\t- Make accounting scalable on SMP systems by splitting the usage\n\t counter to be per-cpu\n\t- Move the code from kernel/cpu_acct.c to kernel/sched.c (since the\n\t code is not big enough to warrant a new file and also this rightly\n\t needs to live inside the scheduler. Also things like accessing\n\t rq-\u003elock while reading cpu usage becomes easier if the code lived in\n\t kernel/sched.c)\n\nThe patch also modifies the cpu controller not to provide the same accounting\ninformation.\n\nTested-by: Balbir Singh \u003cbalbir@linux.vnet.ibm.com\u003e\n\n Tested the patches on top of 2.6.24-rc3. The patches work fine. Ran\n some simple tests like cpuspin (spin on the cpu), ran several tasks in\n the same group and timed them. Compared their time stamps with\n cpuacct.usage.\n\nSigned-off-by: Srivatsa Vaddagiri \u003cvatsa@linux.vnet.ibm.com\u003e\nSigned-off-by: Balbir Singh \u003cbalbir@linux.vnet.ibm.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "e6ceb32aa25fc33f21af84cc7a32fe289b3e860c", "tree": "6a7684a5ac0f841a0bb85ce3a679e5836bd0e2df", "parents": [ "14816b1e2b0eb24ef41dbe37dcb558338e54a603" ], "author": { "name": "Scott James Remnant", "email": "scott@ubuntu.com", "time": "Wed Nov 28 16:22:07 2007 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Thu Nov 29 09:24:55 2007 -0800" }, "message": "wait_task_stopped(): pass correct exit_code to wait_noreap_copyout()\n\nIn wait_task_stopped() exit_code already contains the right value for the\nsi_status member of siginfo, and this is simply set in the non WNOWAIT\ncase.\n\nIf you call waitid() with a stopped or traced process, you\u0027ll get the signal\nin siginfo.si_status as expected -- however if you call waitid(WNOWAIT) at the\nsame time, you\u0027ll get the signal \u003c\u003c 8 | 0x7f\n\nPass it unchanged to wait_noreap_copyout(); we would only need to shift it\nand add 0x7f if we were returning it in the user status field and that\nisn\u0027t used for any function that permits WNOWAIT.\n\nSigned-off-by: Scott James Remnant \u003cscott@ubuntu.com\u003e\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nCc: Roland McGrath \u003croland@redhat.com\u003e\nCc: \u003cstable@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "9e6c1e633355b69803094ecbac4cecc96e00965c", "tree": "ce46f805fce9cff904a2646521322334c201eadc", "parents": [ "8853c202b4a91713dbfb4d9b6e1c87cc2aa12392" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Wed Nov 28 16:22:04 2007 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Thu Nov 29 09:24:54 2007 -0800" }, "message": "FRV: fix the extern declaration of kallsyms_num_syms\n\nFix the extern declaration of kallsyms_num_syms to indicate that the symbol\ndoes not reside in the small-data storage space, and so may not be accessed\nrelative to the small data base register.\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "32df81cbd5b41d281cc3d7e7ff6a98ac6201e197", "tree": "61fa5ac58e6b74a571ed2ac605454218bd0c75c6", "parents": [ "48986f06b6bc6f435debcfad0a748ce35f0a52df" ], "author": { "name": "Pavel Emelyanov", "email": "xemul@openvz.org", "time": "Wed Nov 28 16:21:38 2007 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Thu Nov 29 09:24:53 2007 -0800" }, "message": "Isolate the UTS namespace\u0027s domainname and hostname back\n\nCommit 7d69a1f4a72b18876c99c697692b78339d491568 (\"remove CONFIG_UTS_NS\nand CONFIG_IPC_NS\") by Cedric Le Goater accidentally removed the code\nthat prevented the uts-\u003ehostname and uts-\u003edomainname values from being\noverwritten from another namespace.\n\nIn other words, setting hostname/domainname via sysfs (echo xxx \u003e\n/proc/sys/kernel/(host|domain)name) cased the new value to be set in\ninit UTS namespace only.\n\nReturn the isolation back.\n\nSigned-off-by: Pavel Emelyanov \u003cxemul@openvz.org\u003e\nAcked-by: Cedric Le Goater \u003cclg@fr.ibm.com\u003e\nAcked-by: Serge Hallyn \u003cserue@us.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "c895078355b6b6e05c60aa205892526dd3390f0a", "tree": "922a0b9204b0cfcd5c59762f4d02e167d587ccd2", "parents": [ "c2319540cd7330fa9066e5b9b84d357a2c8631a2" ], "author": { "name": "Oleg Nesterov", "email": "oleg@tv-sign.ru", "time": "Wed Nov 28 16:21:24 2007 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Thu Nov 29 09:24:52 2007 -0800" }, "message": "wait_task_stopped(): don\u0027t use task_pid_nr_ns() lockless\n\nwait_task_stopped(WNOWAIT) does task_pid_nr_ns() without tasklist/rcu lock,\nwe can read an already freed memory.
