Previous to this commit\ninotify acted like the following:\n\n inotify_add_watch(X, Y, Z) \u003d 1\n inotify_rm_watch(X, 1);\n inotify_add_watch(X, Y, Z) \u003d 2\n\nbut after this patch inotify would return watch descriptors like so:\n\n inotify_add_watch(X, Y, Z) \u003d 1\n inotify_rm_watch(X, 1);\n inotify_add_watch(X, Y, Z) \u003d 1\n\nwhich I saw as equivalent to opening an fd where\n\n open(file) \u003d 1;\n close(1);\n open(file) \u003d 1;\n\nseemed perfectly reasonable. The issue is that quite a bit of userspace\napparently relies on the behavior in which watch descriptors will not be\nquickly reused. KDE relies on it, I know some selinux packages rely on\nit, and I have heard complaints from other random sources such as debian\nbug 558981.\n\nAlthough the man page implies what we do is ok, we broke userspace so\nthis patch almost reverts us to the old behavior. It is still slightly\nracey and I have patches that would fix that, but they are rather large\nand this will fix it for all real world cases. The race is as follows:\n\n - task1 creates a watch and blocks in idr_new_watch() before it updates\n the hint.\n - task2 creates a watch and updates the hint.\n - task1 updates the hint with it\u0027s older wd\n - task removes the watch created by task2\n - task adds a new watch and will reuse the wd originally given to task2\n\nit requires moving some locking around the hint (last_wd) but this should\nsolve it for the real world and be -stable safe.\n\nAs a side effect this patch papers over a bug in the lib/idr code which\nis causing a large number WARN\u0027s to pop on people\u0027s system and many\nreports in kerneloops.org.

The NOMMU code path\nalways passes PROT_EXEC to the mmap() call. While this doesn\u0027t matter\nto most people whilst the code is running, it will cause a pointless\nicache flush when starting every FDPIC application. Typically this\nicache flush will be of a region on the order of 128KB in size, or may\nbe the entire icache, depending on the facilities available on the CPU.\n\nIn the case where the arch default behaviour seems to be desired\n(EXSTACK_DEFAULT), we probe VM_STACK_FLAGS for VM_EXEC to determine\nwhether we should be setting PROT_EXEC or not.\n\nFor arches that support an MPU (Memory Protection Unit - an MMU without\nthe virtual mapping capability), setting PROT_EXEC or not will make an\nimportant difference.\n\nIt should be noted that this change also affects the executability of\nthe brk region, since ELF-FDPIC has that share with the stack. However,\nthis is probably irrelevant as NOMMU programs aren\u0027t likely to use the\nbrk region, preferring instead allocation via mmap().\n\nSigned-off-by: Mike Frysinger \u003cvapier@gentoo.org\u003e\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "93939f4e5df30e6229a0b5257fdcaf3faf88471c", "tree": "f30acb3e4a35ea96b342f3b1dd25700e7b531def", "parents": [ "b1c0ec8966fa79891b796f58bf2bda1026ca5566", "b292cf9ce70d221c3f04ff62db5ab13d9a249ca8" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Jan 06 18:10:15 2010 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Jan 06 18:10:15 2010 -0800" }, "message": "Merge branch \u0027for-2.6.33\u0027 of git://linux-nfs.org/~bfields/linux\n\n* \u0027for-2.6.33\u0027 of git://linux-nfs.org/~bfields/linux:\n sunrpc: fix peername failed on closed listener\n nfsd: make sure data is on disk before calling -\u003efsync\n nfsd: fix \"insecure\" export option\n" }, { "commit": "56335936de1a41c8978fde62b2158af77ddc7258", "tree": "f0061bef629a1c6a14e08f1b660b3beca0adc7cd", "parents": [ "6c8530993e1fdf1d6af0403e796fe14d80b4b097" ], "author": { "name": "OGAWA Hirofumi", "email": "hirofumi@mail.parknet.co.jp", "time": "Wed Jan 06 18:48:26 2010 -0500" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Wed Jan 06 18:48:26 2010 -0500" }, "message": "nfs: fix oops in nfs_rename()\n\nRecent change is missing to update \"rehash\".
