Since the VFS can\u0027t find an entry\nfor \"foo\" under /mount/submount, it calls into the autofs4 kernel module to\nallocate a new dentry, D1. The kernel creates a new waitq for this lookup and\ncalls the daemon to perform the mount.\n\nThe daemon performs a mkdir of the \"foo\" directory under /mount/submount,\nwhich ends up creating a *new* dentry, D2.\n\nThen, P2 does a lookup of /mount/submount/foo. The VFS path walking logic\nfinds a dentry in the dcache, D2, and calls the revalidate function with this.\n In the autofs4 revalidate code, we then trigger a mount, since the dentry is\nan empty directory that isn\u0027t a mountpoint, and so set DCACHE_AUTOFS_PENDING\nand call into the wait code to trigger the mount.\n\nThe wait code finds our existing waitq entry (since it is keyed off of the\ndirectory name) and adds itself to the list of waiters.\n\nAfter the daemon finishes the mount, it calls back into the kernel to release\nthe waiters. When this happens, P1 is woken up and goes about clearing the\nDCACHE_AUTOFS_PENDING flag, but it does this in D1! So, given that P1 in our\ncase is a program that will immediately try to access a file under\n/mount/submount/foo, we end up finding the dentry D2 which still has the\npending flag set, and we set out to wait for a mount *again*!\n\nSo, one way to address this is to re-do the lookup at the end of\ntry_to_fill_dentry, and to clear the pending flag on the hashed dentry. This\nseems a sane approach to me.\"\n\nAnd Jeff\u0027s patch does this.\n\nSigned-off-by: Jeff Moyer \u003cjmoyer@redhat.com\u003e\nSigned-off-by-by: Ian Kent \u003craven@themaw.net\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "cab0936aac8aa907c6bb814c2cf26385478f254b", "tree": "7f0bcb8838f9cc2fd461a6468464042c6b94e987", "parents": [ "afec570c32a0d116e3c68af583ed1d11110f12fc" ], "author": { "name": "Ian Kent", "email": "raven@themaw.net", "time": "Thu May 01 04:35:07 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu May 01 08:04:01 2008 -0700" }, "message": "autofs4: check for invalid dentry in getpath\n\nCatch invalid dentry when calculating its path.\n\nSigned-off-by: Ian Kent \u003craven@themaw.net\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "afec570c32a0d116e3c68af583ed1d11110f12fc", "tree": "1246c52aeccc6daa629e4d8daa523573aabe686e", "parents": [ "c32e026efc1e1a4f9e36babebf123f2b88205b0b" ], "author": { "name": "Ian Kent", "email": "raven@themaw.net", "time": "Thu May 01 04:35:06 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu May 01 08:04:01 2008 -0700" }, "message": "autofs4: fix sparse warning in waitq.c:autofs4_expire_indirect()\n\nRe-order some code in expire.c:autofs4_expire_indirect() to avoid compile\nwarning, reported by Harvey Harrison:\n\n CHECK fs/autofs4/expire.c\nfs/autofs4/expire.c:383:2: warning: context imbalance in\n\u0027autofs4_expire_indirect\u0027 - unexpected unlock\n\nSigned-off-by: Ian Kent \u003craven@themaw.net\u003e\nReviewed-by: Harvey Harrison \u003charvey.harrison@gmail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "02c6be615f1fcd37ac5ed93a3ad6692ad8991cd9", "tree": "9c5047ed8b165a3388d5c61b2702f7cc12954766", "parents": [ "2850699c59d513a0cd0c68f60f75609a5f9d4d32" ], "author": { "name": "Miklos Szeredi", "email": "mszeredi@suse.cz", "time": "Thu May 01 04:34:45 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu May 01 08:03:59 2008 -0700" }, "message": "vfs: fix permission checking in sys_utimensat\n\nIf utimensat() is called with both times set to UTIME_NOW or one of them to\nUTIME_NOW and the other to UTIME_OMIT, then it will update the file time\nwithout any permission checking.\n\nI don\u0027t think this can be used for anything other than a local DoS, but could\nbe quite bewildering at that (e.g. \"Why was that large source tree rebuilt\nwhen I didn\u0027t modify anything???\")\n\nThis affects all kernels from 2.6.22, when the utimensat() syscall was\nintroduced.\n\nFix by doing the same permission checking as for the \"times \u003d\u003d NULL\" case.\n\nThanks to Michael Kerrisk, whose utimensat-non-conformances-and-fixes.patch in\n-mm also fixes this (and breaks other stuff), only he didn\u0027t realize the\nsecurity implications of this bug.\n\nSigned-off-by: Miklos Szeredi \u003cmszeredi@suse.cz\u003e\nCc: Ulrich Drepper \u003cdrepper@redhat.com\u003e\nCc: Michael Kerrisk \u003cmtk-manpages@gmx.net\u003e\nCc: \u003cstable@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "590fe34c47cb5c2d836ac76fabc5f160bf31a3f1", "tree": "9a5d9a855629b916597582796391564891acf9a4", "parents": [ "4e571aba7bb25a3a069a7b88c0f63fe5a14c05c6" ], "author": { "name": "David Woodhouse", "email": "dwmw2@infradead.org", "time": "Thu May 01 15:53:28 2008 +0100" }, "committer": { "name": "David Woodhouse", "email": "dwmw2@infradead.org", "time": "Thu May 01 15:53:28 2008 +0100" }, "message": "[JFFS2] Quiet lockdep false positive.\n\nDon\u0027t hold f-\u003esem while calling into jffs2_do_create().

For most attributes, this doesn\u0027t change the\n\"real\" size of the file i.e. how much can be read from it. However, the\nparameter validation for reading and writing binary attribute files is based\non the inode size and not the size specified in the file\u0027s bin_attribute, so it\ncan be broken by this. For example, if we try using dd to write to such a file:\n\n# pwd\n/sys/bus/pci/devices/0000:08:00.0\n# ls -l config\n-rw-r--r-- 1 root root 4096 Feb 1 17:35 config\n# dd if\u003d/dev/zero of\u003dconfig bs\u003d4 count\u003d1\n1+0 records in\n1+0 records out\n# ls -l config\n-rw-r--r-- 1 root root 0 Feb 1 17:50 config\n# dd if\u003d/dev/zero of\u003dconfig bs\u003d4 count\u003d1 seek\u003d128\ndd: writing `config\u0027: No space left on device\n1+0 records in\n0+0 records out\n\nAlso, after truncation to 0, parameter validation for read and write is\ndisabled. Most bin_attribute read and write methods also validate the size and\noffset, but for some this will allow out-of-range access. This may be a\nsecurity issue, though access to such files is often limited to root. In any\ncase, the validation should remain for safety\u0027s sake!)\n\nThis was previously reported in Bugzilla as bug 9867.\n\nsysfs should ignore size changes or else refuse them (by returning

I\u0027d claim that they\n are almost impossible, unless you limit them somehow (shared\n writable mappings are the nastiest part - if you don\u0027t have those,\n you can reasonably limit your problems by limiting the number of\n dirty pages you accept through normal \"write()\" calls).\"\n\nInstead of attempting the impossible, I\u0027ve just waited for the dirty page\naccounting infrastructure to materialize (thanks to Peter Zijlstra and\nothers). This nicely solved the biggest problem: limiting the number of pages\nused for write caching.\n\nSome small details remained, however, which this largish patch attempts to\naddress. It provides a page writeback implementation for fuse, which is\ncompletely safe against VM related deadlocks. Performance may not be very\ngood for certain usage patterns, but generally it should be acceptable.\n\nIt has been tested extensively with fsx-linux and bash-shared-mapping.\n\nFuse page writeback design\n--------------------------\n\nfuse_writepage() allocates a new temporary page with GFP_NOFS|__GFP_HIGHMEM.\nIt copies the contents of the original page, and queues a WRITE request to the\nuserspace filesystem using this temp page.\n\nThe writeback is finished instantly from the MM\u0027s point of view: the page is\nremoved from the radix trees, and the PageDirty and PageWriteback flags are\ncleared.\n\nFor the duration of the actual write, the NR_WRITEBACK_TEMP counter is\nincremented. The per-bdi writeback count is not decremented until the actual\nwrite completes.\n\nOn dirtying the page, fuse waits for a previous write to finish before\nproceeding. This makes sure, there can only be one temporary page used at a\ntime for one cached page.\n\nThis approach is wasteful in both memory and CPU bandwidth, so why is this\ncomplication needed?\n\nThe basic problem is that there can be no guarantee about the time in which\nthe userspace filesystem will complete a write. It may be buggy or even\nmalicious, and fail to complete WRITE requests. We don\u0027t want unrelated parts\nof the system to grind to a halt in such cases.\n\nAlso a filesystem may need additional resources (particularly memory) to\ncomplete a WRITE request. There\u0027s a great danger of a deadlock if that\nallocation may wait for the writepage to finish.\n\nCurrently there are several cases where the kernel can block on page\nwriteback:\n\n - allocation order is larger than PAGE_ALLOC_COSTLY_ORDER\n - page migration\n - throttle_vm_writeout (through NR_WRITEBACK)\n - sync(2)\n\nOf course in some cases (fsync, msync) we explicitly want to allow blocking.\nSo for these cases new code has to be added to fuse, since the VM is not\ntracking writeback pages for us any more.\n\nAs an extra safetly measure, the maximum dirty ratio allocated to a single\nfuse filesystem is set to 1% by default. This way one (or several) buggy or\nmalicious fuse filesystems cannot slow down the rest of the system by hogging\ndirty memory.\n\nWith appropriate privileges, this limit can be raised through\n\u0027/sys/class/bdi/\u003cbdi\u003e/max_ratio\u0027.\n\nSigned-off-by: Miklos Szeredi \u003cmszeredi@suse.cz\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "fc3ba692a4d19019387c5acaea63131f9eab05dd", "tree": "c86e025cb8f79c7ffc479029989b7378bcb9f285", "parents": [ "dd5656e59ca7b25fb60a22f9079905ed0da5ed0c" ], "author": { "name": "Miklos Szeredi", "email": "mszeredi@suse.cz", "time": "Wed Apr 30 00:54:38 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Apr 30 08:29:50 2008 -0700" }, "message": "mm: Add NR_WRITEBACK_TEMP counter\n\nFuse will use temporary buffers to write back dirty data from memory mappings\n(normal writes are done synchronously).
