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. After returning from the fault\nhandling we reacquire the hash bucket lock and check whether the\npi_state owner has been modified already.\n\nReported-by: David Holmes \u003cdavid.holmes@sun.com\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nCc: David Holmes \u003cdavid.holmes@sun.com\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: \u003cstable@kernel.org\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n\n kernel/futex.c | 93 ++++++++++++++++++++++++++++++++++++++++++++-------------\n 1 file changed, 73 insertions(+), 20 deletions(-)\n" }, { "commit": "3e14b50dd4a3178f4f635267a2706b5d4f8c61ee", "tree": "3d16b9fbd8903a084b1e174dcb4f68aed94337eb", "parents": [ "44e051773da465f8c92127914bc784770e0e2a28" ], "author": { "name": "Takashi Iwai", "email": "tiwai@suse.de", "time": "Mon Jun 23 11:58:06 2008 +0200" }, "committer": { "name": "Takashi Iwai", "email": "tiwai@suse.de", "time": "Mon Jun 23 12:06:23 2008 +0200" }, "message": "ALSA: sb - Fix wrong assertions\n\nsnd_assert() in save_mixer() and restore_mixer() in sb_mixer.c is\njust wrong.
