This means that\nthe kernel internal pi_state and the user space futex variable are out\nof sync. First we assumed that this is a user space data corruption,\nbut deeper investigation revieled that the problem happend because the\npi-futex code is not handling a fault in the futex_lock_pi path when\nthe user space variable needs to be fixed up.\n\nThe fault happens when a fork mapped the anon memory which contains\nthe futex readonly for COW or the page got swapped out exactly between\nthe unlock of the futex and the return of either the new futex owner\nor the task which was the expected owner but failed to acquire the\nkernel internal rtmutex. The current futex_lock_pi() code drops out\nwith an inconsistent in case it faults and returns -EFAULT to user\nspace. User space has no way to fixup that state.\n\nWhen we wrote this code we thought that we could not drop the hash\nbucket lock at this point to handle the fault.\n\nAfter analysing the code again it turned out to be wrong because there\nare only two tasks involved which might modify the pi_state and the\nuser space variable:\n\n - the task which acquired the rtmutex\n - the pending owner of the pi_state which did not get the rtmutex\n\nBoth tasks drop into the fixup_pi_state() function before returning to\nuser space. The first task which acquired the hash bucket lock faults\nin the fixup of the user space variable, drops the spinlock and calls\nfutex_handle_fault() to fault in the page. Now the second task could\nacquire the hash bucket lock and tries to fixup the user space\nvariable as well. It either faults as well or it succeeds because the\nfirst task already faulted the page in.\n\nOne caveat is to avoid a double fixup.

function prologue and epilogue stuff, even though\nit was itself then inside a C function where the compiler would add its\nown prologue and epilogue on top of it all.\n\nThis then just _happened_ to work if you had exactly the right compiler\nversion and exactly the right compiler flags, so that gcc just happened\nto not create any prologue at all (the gcc-generated epilogue wouldn\u0027t\nmatter, since it would never be reached).\n\nBut the more proper way to fix it is to simply not do this. Move the\ninline asm to the top level, with no surrounding function at all (the\nbetter alternative would be to remove the prologue and make it actually\nuse proper description of the arguments to the inline asm, but that\u0027s a\nbigger change than the one I\u0027m willing to make right now).\n\nTested-by: S.Çağlar Onur \u003ccaglar@pardus.org.tr\u003e\nAcked-by: Thomas Mingarelli \u003cThomas.Mingarelli@hp.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "e0c6d97c65e0784aade7e97b9411f245a6c543e7", "tree": "dd860efd59feb48050598035301628b79b5b954f", "parents": [ "9bedbcb207ed9a571b239231d99c8fd4a34ae24d" ], "author": { "name": "Cliff Wickman", "email": "cpw@sgi.com", "time": "Fri Jun 20 12:02:00 2008 -0700" }, "committer": { "name": "Tony Luck", "email": "tony.luck@intel.com", "time": "Fri Jun 20 12:02:00 2008 -0700" }, "message": "[IA64] SN2: security hole in sn2_ptc_proc_write\n\nSecurity hole in sn2_ptc_proc_write\n\nIt is possible to overrun a buffer with a write to this /proc file.\n\nSigned-off-by: Cliff Wickman \u003ccpw@sgi.com\u003e\nSigned-off-by: Tony Luck \u003ctony.luck@intel.com\u003e\n" }, { "commit": "ac1623625c5818bbdf5c68973098ba386ba7a004", "tree": "64376f6da43c93abf1c841e247c30d30377fd407", "parents": [ "a49c06bfe48c43b4fea4d3789807d8393828ca8a" ], "author": { "name": "Ben Dooks", "email": "ben-linux@fluff.org", "time": "Fri Jun 20 20:53:35 2008 +0200" }, "committer": { "name": "Bartlomiej Zolnierkiewicz", "email": "bzolnier@gmail.com", "time": "Fri Jun 20 20:53:35 2008 +0200" }, "message": "BAST: Remove old IDE driver\n\nRemove the old BAST IDE driver, as we are now using the platform-pata\nsupport.\n\nSigned-off-by: Ben Dooks \u003cben-linux@fluff.org\u003e\nCc: Jeff Garzik \u003cjgarzik@pobox.com\u003e\nSigned-off-by: Bartlomiej Zolnierkiewicz \u003cbzolnier@gmail.com\u003e\n" }, { "commit": "a49c06bfe48c43b4fea4d3789807d8393828ca8a", "tree": "7350eb6ef7fc2d246c6f248eac5390f2c47408cb", "parents": [ "a17bf220231a5061a29a27a99a273246eb3b156e" ], "author": { "name": "Christophe Niclaes", "email": "cniclaes@develtech.com", "time": "Fri Jun 20 20:53:34 2008 +0200" }, "committer": { "name": "Bartlomiej Zolnierkiewicz", "email": "bzolnier@gmail.com", "time": "Fri Jun 20 20:53:34 2008 +0200" }, "message": "pcmcia ide kingston compactflash\u0027s have a new manufacturer id\n\nUp to now, Kingston compactflash cards (ab)used the Toshiba Manufacturer\u0027s ID,\nIn their new CF cards, they use a new one.

The anomaly was due to the following\nreason. When a process leaves the CPU and immediately starts waiting for\nCPU on the runqueue (which means it remains in the TASK_RUNNABLE state),\nthe time of re-entry into the run-queue is never recorded. Due to this,\nthe waiting time on the runqueue from this point of re-entry upto the\nnext time it hits the CPU is not accounted for. This is solved by\nrecording the time of re-entry of a process leaving the CPU in the\nsched_info_depart() function IF the process will go back to waiting on\nthe run-queue. This IF condition is verified by checking whether the\nprocess is still in the TASK_RUNNABLE state.\n\nThe patch was tested on 2.6.26-rc6 using two simple CPU hog programs.\nThe values noted prior to the fix did not account for the time spent on\nthe runqueue waiting.

Thus early calls to native_sched_clock() would skip\nthe TSC and use jiffies instead.\n\nAfter the commit above, tsc_32.c uses a \"tsc_disabled\" variable\nwhich defaults to 0, meaning that the TSC is Ok to use. Early calls\nto native_sched_clock() now erroneously try to use the TSC on\n!cpu_has_tsc processors, leading to invalid opcode exceptions.\n\nMy proposed fix is to initialise tsc_disabled to a \"soft disabled\"\nstate distinct from the hard disabled state set up by the \"notsc\"\nkernel option. This fixes the native_sched_clock() problem. It also\nallows tsc_init() to be simplified: instead of setting tsc_disabled \u003d 1\non every error return, we just set tsc_disabled \u003d 0 once when all\nchecks have succeeded.\n\nI\u0027ve verified that this lets my 486 boot again. I\u0027ve also verified\nthat a Core2 machine still uses the TSC as clocksource after the patch.\n\nSigned-off-by: Mikael Pettersson \u003cmikpe@it.uu.se\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "75118a82e21cafb4a82b53bb85d1c7689787e046", "tree": "f0de9e9058f6396230bb308fae8c167f33da0701", "parents": [ "ad524d46f36bbc32033bb72ba42958f12bf49b06" ], "author": { "name": "Suresh Siddha", "email": "suresh.b.siddha@intel.com", "time": "Fri Jun 13 15:47:12 2008 -0700" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Jun 19 10:08:45 2008 +0200" }, "message": "x86: fix NULL pointer deref in __switch_to\n\nPatrick McHardy reported a crash:\n\n\u003e \u003e I get this oops once a day, its apparently triggered by something\n\u003e \u003e run by cron, but the process is a different one each time.\n\u003e \u003e\n\u003e \u003e Kernel is -git from yesterday shortly before the -rc6 release\n\u003e \u003e (last commit is the usb-2.6 merge, the x86 patches are missing),\n\u003e \u003e .config is attached.\n\u003e \u003e\n\u003e \u003e I\u0027ll retry with current -git, but the patches that have gone in\n\u003e \u003e since I last updated don\u0027t look related.\n\u003e \u003e\n\u003e \u003e [62060.043009] BUG: unable to handle kernel NULL pointer dereference at\n\u003e \u003e 000001ff\n\u003e \u003e [62060.043009] IP: [\u003cc0102a9b\u003e] __switch_to+0x2f/0x118\n\u003e \u003e [62060.043009] *pde \u003d 00000000\n\u003e \u003e [62060.043009] Oops: 0002 [#1] PREEMPT\n\nVegard Nossum analyzed it:\n\n\u003e This decodes to\n\u003e\n\u003e 0: 0f ae 00 fxsave (%eax)\n\u003e\n\u003e so it\u0027s related to the floating-point context.
