This was\nimplemented by setting sub_info.wait to 0 (implicitly), and doing a\nwait_for_completion().\n\nAs part of the cleanup done in 0ab4dc92278a0f3816e486d6350c6652a72e06c8,\ncall_usermodehelper_pipe() was changed to pass 1 as the value for wait to\ncall_usermodehelper_exec().\n\nThis is equivalent to setting sub_info.wait to 1, which is a change from\nthe previous behaviour. Using 1 instead of 0 causes\n__call_usermodehelper() to start the kernel thread running\nwait_for_helper(), rather than directly calling ____call_usermodehelper().\n\nThe end result is that the calling kernel code blocks until the user mode\nhelper finishes. As the helper is expecting input on stdin, and now no one\nis writing anything, everything locks up (observed in do_coredump).\n\nThe fix is to change the 1 to UMH_WAIT_EXEC (aka 0), indicating that we\nwant to wait for the kernel thread to be started, but not for the helper to\nfinish.\n\nSigned-off-by: Michael Ellerman \u003cmichael@ellerman.id.au\u003e\nAcked-by: Andi Kleen \u003cak@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "179c85ea53bef807621f335767e41e23f86f01df", "tree": "6320c1478ebe988b5251a92498836bf3d045642a", "parents": [ "a570ab6f10462b062c28188b64377b8034235761" ], "author": { "name": "Arnd Bergmann", "email": "arnd@arndb.de", "time": "Tue Sep 11 15:23:49 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue Sep 11 17:21:20 2007 -0700" }, "message": "futex_compat: fix list traversal bugs\n\nThe futex list traversal on the compat side appears to have\na bug.\n\nIt\u0027s loop termination condition compares:\n\n while (compat_ptr(uentry) !\u003d \u0026head-\u003elist)\n\nBut that can\u0027t be right because \"uentry\" has the special\n\"pi\" indicator bit still potentially set at bit 0.

that a driver\u0027s irq handler was running both in hard interrupt\nand process contexts with irqs enabled. The latter was done during\nfree_irq() call and was possible only with CONFIG_DEBUG_SHIRQ enabled.\nThis was fixed by another patch.\n\nBut similar problem is possible with request_irq(): any locks taken from\nirq handler could be vulnerable - especially with soft interrupts. This\npatch fixes it by disabling local interrupts during handler\u0027s run. (It\nseems, disabling softirqs should be enough, but it needs more checking\non possible races or other special cases).\n\nReported-by: Mariusz Kozlowski \u003cm.kozlowski@tuxland.pl\u003e\nSigned-off-by: Jarek Poplawski \u003cjarkao2@o2.pl\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "f3de4be9d5f8551d7880a1f1f5231a30e0161b1f", "tree": "9ebd397e6b253d144460f061b95ded60a7b0da0b", "parents": [ "b07e35f94a7b6a059f889b904529ee907dc0634d" ], "author": { "name": "Rafael J.
