Thanks to Mike Galbraith for pointing\nthat out. I compiled and booted this patch with no issues. ]\n\nRe-examining the cpupri patch, I see there\u0027s a possible race because the\nupdate of the two priorities vec-\u003ecounts are not protected by a memory\nbarrier.\n\nWhen a RT runqueue is overloaded and wants to push an RT task to another\nrunqueue, it scans the RT priority vectors in a loop from lowest\npriority to highest.\n\nWhen we queue or dequeue an RT task that changes a runqueue\u0027s highest\npriority task, we update the vectors to show that a runqueue is rated at\na different priority. To do this, we first set the new priority mask,\nand increment the vec-\u003ecount, and then set the old priority mask by\ndecrementing the vec-\u003ecount.\n\nIf we are lowering the runqueue\u0027s RT priority rating, it will trigger a\nRT pull, and we do not care if we miss pushing to this runqueue or not.\n\nBut if we raise the priority, but the priority is still lower than an RT\ntask that is looking to be pushed, we must make sure that this runqueue\nis still seen by the push algorithm (the loop).\n\nBecause the loop reads from lowest to highest, and the new priority is\nset before the old one is cleared, we will either see the new or old\npriority set and the vector will be checked.\n\nBut! Since there\u0027s no memory barrier between the updates of the two, the\nold count may be decremented first before the new count is incremented.\nThis means the loop may see the old count of zero and skip it, and also\nthe new count of zero before it was updated. A possible runqueue that\nthe RT task could move to could be missed.\n\nA conditional memory barrier is placed between the vec-\u003ecount updates\nand is only called when both updates are done.\n\nThe smp_wmb() has also been changed to smp_mb__before_atomic_inc/dec(),\nas they are not needed by archs that already synchronize\natomic_inc/dec().\n\nThe smp_rmb() has been moved to be called at every iteration of the loop\nso that the race between seeing the two updates is visible by each\niteration of the loop, as an arch is free to optimize the reading of\nmemory of the counters in the loop.\n\nSigned-off-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Nick Piggin \u003cnpiggin@kernel.dk\u003e\nCc: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nLink: http://lkml.kernel.org/r/1312547269.18583.194.camel@gandalf.stny.rr.com\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "c92211d9b772792a9dea530c042efb4ab5562f50", "tree": "d4ef2f4aa2e2c0d991a4dbc74a14e305caf46cee", "parents": [ "5181f4a46afd99e5e85c639b189e43e0a42b53df" ], "author": { "name": "Steven Rostedt", "email": "rostedt@goodmis.org", "time": "Tue Aug 02 16:36:12 2011 -0400" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Sun Aug 14 12:01:03 2011 +0200" }, "message": "sched/cpupri: Remove the vec-\u003elock\n\nsched/cpupri: Remove the vec-\u003elock\n\nThe cpupri vec-\u003elock has been showing up as a top contention\nlately. This is because of the RT push/pull logic takes an\nagressive approach for migrating RT tasks. The cpupri logic is\nin place to improve the performance of the push/pull when dealing\nwith large number CPU machines.\n\nThe problem though is a vec-\u003elock is required, where a vec is a\nglobal per RT priority structure. That is, if there are lots of\nRT tasks at the same priority, every time they are added or removed\nfrom the RT queue, this global vec-\u003elock is taken. Now that more\nkernel threads are becoming RT (RCU boost and threaded interrupts)\nthis is becoming much more of an issue.\n\nThere are two variables that are being synced by the vec-\u003elock.\nThe cpupri bitmask, and the vec-\u003ecounter. The cpupri bitmask\nis one bit per priority. If a RT priority vec has a process queued,\nthen the vec-\u003ecount is \u003e 0 and the cpupri bitmask is set for that\nRT priority.\n\nIf the cpupri bitmask gets out of sync with the vec-\u003ecounter, we could\nend up pushing a low proirity RT task to a high priority queue.\nThat RT task that could have run immediately could be queued on a\nrun queue with a higher priority task indefinitely.\n\nThe solution is not to use the cpupri bitmask and just look at the\nvec-\u003ecount directly when doing a pull. The cpupri bitmask is just\na fast way to scan the RT priorities when a pull is made. Instead\nof using the bitmask, and just examine all RT priorities, and\nlook at the vec-\u003ecounts, we could eliminate the vec-\u003elock. The\nscan of RT tasks is to find a run queue that we can push an RT task\nto, and we do not push to a high priority queue, thus the scan only\nneeds to go from 1 to RT task-\u003eprio, and not all 100 RT priorities.\n\nThe push algorithm, which does the scan of RT priorities (and\nscan of the bitmask) only happens when we have an overloaded RT run\nqueue (more than one RT task queued). The grabbing of the vec-\u003elock\nhappens every time any RT task is queued or dequeued on the run\nqueue for that priority. The slowing down of the scan by not using\na bitmask is negligible by the speed up of removing the vec-\u003elock\ncontention, and replacing it with an atomic counter and memory barrier.\n\nTo prove this, I wrote a patch that times both the loop and the code\nthat grabs the vec-\u003elocks. I passed the patches to various people\n(and companies) to test and show the results. I let everyone choose\ntheir own load to test, giving different loads on the system,\nfor various different setups.\n\nHere\u0027s some of the results: (snipping to a few CPUs to not make\nthis change log huge, but the results were consistent across\nthe entire system).\n\nSystem 1 (24 CPUs)\n\nBefore patch:\nCPU: Name Count Max Min Average Total\n---- ---- ----- --- --- ------- -----\n[...]\ncpu 20: loop 3057 1.766 0.061 0.642 1963.170\n vec 6782949 90.469 0.089 0.414 2811760.503\ncpu 21: loop 2617 1.723 0.062 0.641 1679.074\n vec 6782810 90.499 0.089 0.291 1978499.900\ncpu 22: loop 2212 1.863 0.063 0.699 1547.160\n vec 6767244 85.685 0.089 0.435 2949676.898\ncpu 23: loop 2320 2.013 0.062 0.594 1380.265\n vec 6781694 87.923 0.088 0.431 2928538.224\n\nAfter patch:\ncpu 20: loop 2078 1.579 0.061 0.533 1108.006\n vec 6164555 5.704 0.060 0.143 885185.809\ncpu 21: loop 2268 1.712 0.065 0.575 1305.248\n vec 6153376 5.558 0.060 0.187 1154960.469\ncpu 22: loop 1542 1.639 0.095 0.533 823.249\n vec 6156510 5.720 0.060 0.190 1172727.232\ncpu 23: loop 1650 1.733 0.068 0.545 900.781\n vec 6170784 5.533 0.060 0.167 1034287.953\n\nAll times are in microseconds.

The problem\nwith his patch was that it caused more false checks. Because we check a run\nqueue for pushable tasks if the current priority of that run queue is higher\nin priority than the task about to run on our run queue. But after grabbing\nthe locks and doing the real check, we find that there may not be a task\nthat has a higher prio task to pull. Thus the locks were taken with nothing to\ndo.\n\nI added some trace_printks() to record when and how many times the run queue\nlocks were taken to check for pullable tasks, compared to how many times we\npulled a task.\n\nWith the current method, it was:\n\n 3806 locks taken vs 2812 pulled tasks\n\nWith Hillf\u0027s patch:\n\n 6728 locks taken vs 2804 pulled tasks\n\nThe number of times locks were taken to pull a task went up almost double with\nno more success rate.\n\nBut his patch did get me thinking. When we look at the priority of the highest\ntask to consider taking the locks to do a pull, a failure to pull can be one\nof the following: (in order of most likely)\n\n o RT task was pushed off already between the check and taking the lock\n o Waiting RT task can not be migrated\n o RT task\u0027s CPU affinity does not include the target run queue\u0027s CPU\n o RT task\u0027s priority changed between the check and taking the lock\n\nAnd with Hillf\u0027s patch, the thing that caused most of the failures, is\nthe RT task to pull was not at the right priority to pull (not greater than\nthe current RT task priority on the target run queue).\n\nMost of the above cases we can\u0027t help. But the current method does not check\nif the next highest prio RT task can be migrated or not, and if it can not,\nwe still grab the locks to do the test (we don\u0027t find out about this fact until\nafter we have the locks). I thought about this case, and realized that the\npushable task plist that is maintained only holds RT tasks that can migrate.\nIf we move the calculating of the next highest prio task from the inc/dec_rt_task()\nfunctions into the queuing of the pushable tasks, then we only measure the\npriorities of those tasks that we push, and we get this basically for free.\n\nNot only does this patch make the code a little more efficient, it cleans it\nup and makes it a little simpler.\n\nThanks to Hillf Danton for inspiring me on this patch.\n\nSigned-off-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Hillf Danton \u003cdhillf@gmail.com\u003e\nCc: Gregory Haskins \u003cghaskins@novell.com\u003e\nLink: http://lkml.kernel.org/r/BANLkTimQ67180HxCx5vgMqumqw1EkFh3qg@mail.gmail.com\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "c37495fd0f64fc139b5a07d242bcb485174d1206", "tree": "0b60964cdb549e5e455d560aa4397102a666a617", "parents": [ "1812a643ccbfeb61a00a7f0d7219606e63d8815b" ], "author": { "name": "Steven Rostedt", "email": "srostedt@redhat.com", "time": "Thu Jun 16 21:55:22 2011 -0400" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Sun Aug 14 12:00:52 2011 +0200" }, "message": "sched: Balance RT tasks when forked as well\n\nWhen a new task is woken, the code to balance the RT task is currently\nskipped in the select_task_rq() call.

But the check created new security threat: many poorly\nwritten programs simply don\u0027t check setuid() return code and believe it\ncannot fail if executed with root privileges. So, the check is removed\nin this patch because of too often privilege escalations related to\nbuggy programs.\n\nThe NPROC can still be enforced in the common code flow of daemons\nspawning user processes. Most of daemons do fork()+setuid()+execve().\nThe check introduced in execve() (1) enforces the same limit as in\nsetuid() and (2) doesn\u0027t create similar security issues.\n\nNeil Brown suggested to track what specific process has exceeded the\nlimit by setting PF_NPROC_EXCEEDED process flag. With the change only\nthis process would fail on execve(), and other processes\u0027 execve()\nbehaviour is not changed.\n\nSolar Designer suggested to re-check whether NPROC limit is still\nexceeded at the moment of execve(). If the process was sleeping for\ndays between set*uid() and execve(), and the NPROC counter step down\nunder the limit, the defered execve() failure because NPROC limit was\nexceeded days ago would be unexpected. If the limit is not exceeded\nanymore, we clear the flag on successful calls to execve() and fork().\n\nThe flag is also cleared on successful calls to set_user() as the limit\nwas exceeded for the previous user, not the current one.\n\nSimilar check was introduced in -ow patches (without the process flag).\n\nv3 - clear PF_NPROC_EXCEEDED on successful calls to set_user().\n\nReviewed-by: James Morris \u003cjmorris@namei.org\u003e\nSigned-off-by: Vasiliy Kulikov \u003csegoon@openwall.com\u003e\nAcked-by: NeilBrown \u003cneilb@suse.de\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "1d229d54dbc26971142f61c3d271a68db236d178", "tree": "92b4721faa4d966d741d49def90c424b45bd5abc", "parents": [ "d16adea3c9d215d98c6fcccc3f91fa8269f91fac", "7676ebbaf21c3828e6315baadb6fcde448aa79b4" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Aug 11 09:03:48 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Aug 11 09:03:48 2011 -0700" }, "message": "Merge branch \u0027perf-urgent-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip\n\n* \u0027perf-urgent-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:\n perf symbols: Check \u0027/tmp/perf-\u0027 symbol file ownership\n perf sched: Usage leftover from trace -\u003e script rename\n perf sched: Do not delete session object prematurely\n perf tools: Check $HOME/.perfconfig ownership\n perf, x86: Add model 45 SandyBridge support\n perf tools: Add support to install perf python extension\n perf tools: do not look at ./config for configuration\n perf tools: Make clean leaves some files\n perf lock: Dropping unsupported \u0027:r\u0027 modifier\n perf probe: Fix coredump introduced by probe module option\n jump label: Reduce the cycle count by changing the link order\n perf report: Use ui__warning in some more places\n perf python: Add PERF_RECORD_{LOST,READ,SAMPLE} routine tables\n perf evlist: Introduce \u0027disable\u0027 method\n trace events: Update version number reference to new 3.x scheme for EVENT_POWER_TRACING_DEPRECATED\n perf buildid-cache: Zero out buffer of filenames when adding/removing buildid\n" }, { "commit": "d16adea3c9d215d98c6fcccc3f91fa8269f91fac", "tree": "f233699dd0e6213a7c79bdbfec0d4a8e89a1c0da", "parents": [ "a9f729f0e28bb4e4ab0d9e9e3c1675fe4b910f47" ], "author": { "name": "Tracey Dent", "email": "tdent48227@gmail.com", "time": "Thu Aug 11 02:59:00 2011 -0400" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Aug 11 09:02:03 2011 -0700" }, "message": "MAINTAINERS: Update linus\u0027 git repository\n\nChange to new git tree -\n (git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git).\n\nSigned-off-by: Tracey Dent \u003ctdent48227@gmail.com\u003e\nAcked-by: WANG Cong \u003cxiyou.wangcong@gmail.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "a9f729f0e28bb4e4ab0d9e9e3c1675fe4b910f47", "tree": "cfc565cffeb30ffccc1438b1bd88b9a372ed26c3", "parents": [ "54a33b190aa5386dd214b4ad02986445e20e83d1" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Aug 11 08:58:41 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Aug 11 08:58:41 2011 -0700" }, "message": "Revert \"EDAC: Correct Kconfig dependencies\"\n\nThis reverts commit af9d220bac41dc3201893e1601cc7c44f7da4498.\n\nIt turns out that one was meant to be applied on top of the edac.git\ntree in -next that has more i7core_edac changes, but that wasn\u0027t clear\nin the original email.\n\nReported-by: Stephen Rothwell \u003csfr@canb.auug.org.au\u003e\nAcked-by: Borislav Petkov \u003cborislav.petkov@amd.com\u003e\nCc: Randy Dunlap \u003crdunlap@xenotime.net\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "54a33b190aa5386dd214b4ad02986445e20e83d1", "tree": "47f4b28e45bcc2e8c60cc758b8e92f80f446c505", "parents": [ "068ef739127af1faf6f342b56d41ceea89f76c75" ], "author": { "name": "Peng Tao", "email": "bergwolf@gmail.com", "time": "Wed Aug 10 18:29:21 2011 -0400" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Aug 11 08:58:02 2011 -0700" }, "message": "NFS41: make PNFS_BLOCK selectable\n\nPNFS_BLOCK needs BLK_DEV_DM/MD, which is not a dependency for other\npnfs layout drivers.

A warning is printed if this\n happened as a result of a write to /proc/cpu/alignment. The\n user\u0027s UM_WARN bit (if present) is still honoured.\n\n * An alignment\u003d argument from the kernel command-line is now\n honoured, except that the kernel will modify the specified mode\n as described above.

Then passing\na credential and object_id info at the io_state level, private for each\ninode. It would also devise this contraption of rotating the device table\nview for each inode-\u003eino to spread out the device usage.\n\nThis is not compatible with the pnfs-objects standard, demanding that\neach inode can have it\u0027s own layout-info, device-table, and each object\ncomponent it\u0027s own pid, oid and creds.\n\nSo: Bring exofs raid engine to be usable for generic pnfs-objects use by:\n\n* Define an exofs_comp structure that holds obj_id and credential info.\n\n* Break up exofs_layout struct to an exofs_components structure that holds a\n possible array of exofs_comp and the array of devices + the size of the\n arrays.\n\n* Add a \"comps\" parameter to get_io_state() that specifies the ids creds\n and device array to use for each IO.\n\n This enables to keep the layout global, but the device-table view, creds\n and IDs at the inode level. It only adds two 64bit to each inode, since\n some of these members already existed in another form.\n\n* ios raid engine now access layout-info and comps-info through the passed\n pointers. Everything is pre-prepared by caller for generic access of\n these structures and arrays.\n\nAt the exofs Level:\n\n* Super block holds an exofs_components struct that holds the device\n array, previously in layout. The devices there are in device-table\n order. The device-array is twice bigger and repeats the device-table\n twice so now each inode\u0027s device array can point to a random device\n and have a round-robin view of the table, making it compatible to\n previous exofs versions.\n\n* Each inode has an exofs_components struct that is initialized at\n load time, with it\u0027s own view of the device table IDs and creds.\n When doing IO this gets passed to the io_state together with the\n layout.\n\nWhile preforming this change. Bugs where found where credentials with the\nwrong IDs where used to access the different SB objects (super.c). As well\nas some dead code. It was never noticed because the target we use does not\ncheck the credentials.\n\nSigned-off-by: Boaz Harrosh \u003cbharrosh@panasas.com\u003e\n" }, { "commit": "85e44df4748670a1a7d8441b2d75843cdebc478a", "tree": "c5bc0cdf7dad56cc6f3a38f99c88f62325a1e029", "parents": [ "e1042ba0991aab80ced34f7dade6ec25f22b4304" ], "author": { "name": "Boaz Harrosh", "email": "bharrosh@panasas.com", "time": "Mon May 16 15:26:47 2011 +0300" }, "committer": { "name": "Boaz Harrosh", "email": "bharrosh@panasas.com", "time": "Sat Aug 06 19:35:31 2011 -0700" }, "message": "exofs: Move exofs specific osd operations out of ios.c\n\nios.c will be moving to an external library, for use by the\nobjects-layout-driver.
