But in the ordered mode, jbd does with metadata buffers and also\ndata buffers.\n\nActually, journal_commit_transaction() releases only the metadata buffers\nof which release is demanded by journal_unmap_buffer(), and also releases\nthe pages to which they belong if possible.\n\nAs a result, the data buffers of which release is demanded by\njournal_unmap_buffer() remain after a transaction commits. And also the\npages to which they belong remain.\n\nSuch the remained pages don\u0027t have mapping any longer. Due to this fact,\nthere is a possibility that the pages which cannot be estimated remain.\n\nThe metadata buffers marked \u0027BH_Freed\u0027 and the pages to which\nthey belong can be released at \u0027JBD: commit phase 7\u0027.\n\nTherefore, by applying the same code into \u0027JBD: commit phase 2\u0027 (where the\ndata buffers are done with), journal_commit_transaction() can also release\nthe data buffers marked \u0027BH_Freed\u0027 and the pages to which they belong.\n\nAs a result, all the buffers marked \u0027BH_Freed\u0027 can be released, and also\nall the pages to which these buffers belong can be released at\njournal_commit_transaction(). So, the page which cannot be estimated is\nlost.\n\n\u003c\u003cExcerpt of code at \u0027JBD: commit phase 7\u0027\u003e\u003e\n \u003e spin_lock(\u0026journal-\u003ej_list_lock);\n \u003e while (commit_transaction-\u003et_forget) {\n \u003e transaction_t *cp_transaction;\n \u003e struct buffer_head *bh;\n \u003e\n \u003e jh \u003d commit_transaction-\u003et_forget;\n \u003e...\n \u003e if (buffer_freed(bh)) {\n \u003e ^^^^^^^^^^^^^^^^^^^^^^^^\n \u003e clear_buffer_freed(bh);\n \u003e ^^^^^^^^^^^^^^^^^^^^^^^^\n \u003e clear_buffer_jbddirty(bh);\n \u003e }\n \u003e\n \u003e if (buffer_jbddirty(bh)) {\n \u003e JBUFFER_TRACE(jh, \"add to new checkpointing trans\");\n \u003e __journal_insert_checkpoint(jh, commit_transaction);\n \u003e JBUFFER_TRACE(jh, \"refile for checkpoint writeback\");\n \u003e __journal_refile_buffer(jh);\n \u003e jbd_unlock_bh_state(bh);\n \u003e } else {\n \u003e J_ASSERT_BH(bh, !buffer_dirty(bh));\n \u003e ...\n \u003e JBUFFER_TRACE(jh, \"refile or unfile freed buffer\");\n \u003e __journal_refile_buffer(jh);\n \u003e if (!jh-\u003eb_transaction) {\n \u003e jbd_unlock_bh_state(bh);\n \u003e /* needs a brelse */\n \u003e journal_remove_journal_head(bh);\n \u003e release_buffer_page(bh);\n \u003e ^^^^^^^^^^^^^^^^^^^^^^^^\n \u003e } else\n \u003e }\n****************************************************************\n* Apply the code of \"^^^^^^\" lines into \u0027JBD: commit phase 2\u0027 *\n****************************************************************\n\nAt journal_commit_transaction() code, there is one extra message in the\nseries of jbd debug messages.

But we can check for this in the kernel module and\nreturn a fail immediately, without having to send a request to the daemon.\n\nIt is possible to recognise these requests are invalid based on whether\nthe request dentry is negative and its relation to the autofs file system\nroot.\n\nFor example, given the indirect multi-mount map entry:\n\nidm1 \\\n /mm1 \u003cserver\u003e:/\u003cpath1\u003e\n /mm2 \u003cserver\u003e:/\u003cpath2\u003e\n\nFor a request to mount idm1, IS_ROOT((idm1)-\u003ed_parent) will be always be\ntrue and the dentry may be negative. But directories idm1/mm1 and\nidm1/mm2 will always be created as part of the mount request for idm1. So\nany mount request within idm1 itself must have a positive dentry otherwise\nthe map key is invalid.\n\nIn version 4 these multi-mount entries are all mounted and umounted as a\nsingle request and in version 5 the directories idm1/mm1 and idm1/mm2 are\ncreated and an autofs fs mounted on them to act as a mount trigger so the\nabove is also true.\n\nThis also holds true for the autofs version 4 pseudo direct mount feature.\n When this feature is used without the \"--ghost\" option automount(8) will\ncreate internal submounts as we go down the map key paths which are\nessentially normal indirect mounts for which the above holds. If the\n\"--ghost\" option is given the directories for map keys are created at\ndaemon startup so valid map entries correspond to postive dentries in the\nautofs fs.\n\nautofs version 5 direct mount maps are similar except that the IS_ROOT\ncheck is not needed. This has been addressed in a previous patch tittled\n\"autofs4 - detect invalid direct mount requests\".\n\nFor example, given the direct multi-mount map entry:\n\n/test/dm1 \\\n /mm1 \u003cserver\u003e:/\u003cpath1\u003e\n /mm2 \u003cserver\u003e:/\u003cpath2\u003e\n\nAn autofs fs is mounted on /test/dm1 as a trigger mount and when a mount\nis triggered for /test/dm1, the multi-mount offset directories\n/test/dm1/mm1 and /test/dm1/mm2 are created and an autofs fs is mounted on\nthem to act as mount triggers. So valid direct mount requests must always\nhave a positive dentry if they correspond to a valid map entry.\n\nSigned-off-by: Ian Kent \u003craven@themaw.net\u003e\nAcked-by: Jeff Moyer \u003cjmoyer@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "eb3b176796b0e53fd26fce86847231542eb0d198", "tree": "85bd1a2e79e92d1ff52714aa19888ef7e4f80638", "parents": [ "296f7bf78bc5c7a4d772aea580ce800d14040d1a" ], "author": { "name": "Ian Kent", "email": "raven@themaw.net", "time": "Wed Jul 23 21:30:22 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Jul 24 10:47:32 2008 -0700" }, "message": "autofs4: detect invalid direct mount requests\n\nautofs v5 direct and offset mounts within an autofs filesystem are\ntriggered by existing autofs triger mounts so the mount point dentry must\nbe positive.

The autofs\ndaemon will then create the directory \u0027foo\u0027, using a new dentry that will\nbe hashed in the dcache.\n\nBefore the mount completes, another process, P2, tries to walk into the\n\u0027foo\u0027 directory. The vfs path walking code finds an entry for \u0027foo\u0027 and\ncalls the revalidate method. Revalidate finds that the entry is not\nPENDING (because PENDING was never set on the dentry created by the\nmkdir), but it does find the directory is empty. Revalidate calls\ntry_to_fill_dentry, which sets the PENDING flag and then calls into the\nautofs4 wait code to trigger or wait for a mount of \u0027foo\u0027. The wait code\nfinds the entry for \u0027foo\u0027 and goes to sleep waiting for the completion of\nthe mount.\n\nYet another process, P3, tries to walk into the \u0027foo\u0027 directory.

P1 takes the\nwait queue mutex, clears the PENDING flag from the dentry, and removes the\nwaitqueue entry for \u0027foo\u0027 from the list.\n\nWhen it releases the waitq mutex, P3 (eventually) acquires it. At this\ntime, it looks for an existing waitq for \u0027foo\u0027, finds none, and so creates\na new one and calls out to the daemon to mount the \u0027foo\u0027 directory.\n\nNow, the reason that three processes are required to trigger this race is\nthat, because the PENDING flag is not set on the dentry created by mkdir,\nthe window for the race would be way to slim for it to ever occur.\nBasically, between the testing of d_mountpoint(dentry) and the taking of\nthe waitq mutex, the mount would have to complete and the daemon would\nhave to be woken up, and that in turn would have to wake up P1.

In the case of an autofs multi-mount\n where a tree of mount point directories are created this can lead to\n the path walk continuing rather than the dentry being sent to the wait\n queue to wait for request completion. This is because, if the pending\n flag isn\u0027t set, the criteria for deciding this is a mount in progress\n fails to hold, namely that the dentry is not a mount point and has no\n subdirectories.\n\n2) A mount request dentry is initially created negative and unhashed.\n It remains this way until the -\u003emkdir() callback completes. Since it\n is unhashed a fresh dentry is used when the user space mount request\n creates the mount point directory. This leaves the original dentry\n negative and unhashed. But revalidate has no way to tell the VFS that\n the dentry has changed, other than to force another -\u003elookup() by\n returning false, which is at best wastefull and at worst not possible.\n This results in an -ENOENT return from the original path walk when in\n fact the mount succeeded.\n\nTo resolve this we need to ensure that the same dentry is used in all\ncalls to -\u003elookup() during the course of a mount request.

At that point, the next write fault from the parent\ncould fail due to COW if the child still has a reference.\n\nWe only reserve pages for the parent but a copy must be made to avoid\nleaking data from the parent to the child after fork(). Reserves could be\ntaken for both parent and child at fork time to guarantee faults but if\nthe mapping is large it is highly likely we will not have sufficient pages\nfor the reservation, and it is common to fork only to exec() immediatly\nafter. A failure here would be very undesirable.\n\nNote that the current behaviour of mainline with MAP_PRIVATE pages is\npretty bad. The following situation is allowed to occur today.\n\n1. Process calls mmap(MAP_PRIVATE)\n2. Process calls mlock() to fault all pages and makes sure it succeeds\n3. Process forks()\n4. Process writes to MAP_PRIVATE mapping while child still exists\n5. If the COW fails at this point, the process gets SIGKILLed even though it\n had taken care to ensure the pages existed\n\nThis patch improves the situation by guaranteeing the reliability of the\nprocess that successfully calls mmap(). When the parent performs COW, it\nwill try to satisfy the allocation without using reserves. If that fails\nthe parent will steal the page leaving any children without a page.\nFaults from the child after that point will result in failure. If the\nchild COW happens first, an attempt will be made to allocate the page\nwithout reserves and the child will get SIGKILLed on failure.\n\nTo summarise the new behaviour:\n\n1. If the original mapper performs COW on a private mapping with multiple\n references, it will attempt to allocate a hugepage from the pool or\n the buddy allocator without using the existing reserves. On fail, VMAs\n mapping the same area are traversed and the page being COW\u0027d is unmapped\n where found. It will then steal the original page as the last mapper in\n the normal way.\n\n2. The VMAs the pages were unmapped from are flagged to note that pages\n with data no longer exist. Future no-page faults on those VMAs will\n terminate the process as otherwise it would appear that data was corrupted.\n A warning is printed to the console that this situation occured.\n\n2. If the child performs COW first, it will attempt to satisfy the COW\n from the pool if there are enough pages or via the buddy allocator if\n overcommit is allowed and the buddy allocator can satisfy the request. If\n it fails, the child will be killed.\n\nIf the pool is large enough, existing applications will not notice that\nthe reserves were a factor. Existing applications depending on the\nno-reserves been set are unlikely to exist as for much of the history of\nhugetlbfs, pages were prefaulted at mmap(), allocating the pages at that\npoint or failing the mmap().\n\n[npiggin@suse.de: fix CONFIG_HUGETLB\u003dn build]\nSigned-off-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nAcked-by: Adam Litke \u003cagl@us.ibm.com\u003e\nCc: Andy Whitcroft \u003capw@shadowen.org\u003e\nCc: William Lee Irwin III \u003cwli@holomorphy.com\u003e\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nCc: Nick Piggin \u003cnpiggin@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": "a1e78772d72b2616ed20e54896e68e0e7044854e", "tree": "d752dd96c2a4fcc555779a7aa99f95069c9b95ae", "parents": [ "fc1b8a73dd71226902a11928dd5500326e101df9" ], "author": { "name": "Mel Gorman", "email": "mel@csn.ul.ie", "time": "Wed Jul 23 21:27:23 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Jul 24 10:47:16 2008 -0700" }, "message": "hugetlb: reserve huge pages for reliable MAP_PRIVATE hugetlbfs mappings until fork()\n\nThis patch reserves huge pages at mmap() time for MAP_PRIVATE mappings in\na similar manner to the reservations taken for MAP_SHARED mappings.

This list can be very long if there is huge free memory.\n\n- the problem\n\n When shrink_dcache_sb() is called, it scans all dentry_unused linearly\n under spin_lock(), and if dentry-\u003ed_sb is differnt from given\n superblock, scan next dentry. This scan costs very much if there are\n many entries, and very ineffective if there are many superblocks.\n\n IOW, When we need to shrink unused dentries on one dentry, but scans\n unused dentries on all superblocks in the system. For example, we scan\n 500 dentries to unmount a filesystem, but scans 1,000,000 or more unused\n dentries on other superblocks.\n\n In our case , At mounting NFS*, shrink_dcache_sb() is called to shrink\n unused dentries on NFS, but scans 100,000,000 unused dentries on\n superblocks in the system such as local ext3 filesystems. I hear NFS\n mounting took 1 min on some system in use.\n\n* : NFS uses virtual filesystem in rpc layer, so NFS is affected by\n this problem.\n\n 100,000,000 is possible number on large systems.\n\n Per-superblock LRU of unused dentried can reduce the cost in\n reasonable manner.\n\n- How to fix\n\n I found this problem is solved by David Chinner\u0027s \"Per-superblock\n unused dentry LRU lists V3\"(1), so I rebase it and add some fix to\n reclaim with fairness, which is in Andrew Morton\u0027s comments(2).\n\n 1) http://lkml.org/lkml/2006/5/25/318\n 2) http://lkml.org/lkml/2006/5/25/320\n\n Split LRU-list of unused dentries to each superblocks. Then, NFS\n mounting will check dentries under a superblock instead of all. But\n this spliting will break LRU of dentry-unused. So, I\u0027ve attempted to\n make reclaim unused dentrins with fairness by calculate number of\n dentries to scan on this sb based on following way\n\n number of dentries to scan on this sb \u003d\n count * (number of dentries on this sb / number of dentries in the machine)\n\n- ToDo\n - I have to measuring performance number and do stress tests.\n\n - When unmount occurs during prune_dcache(), scanning on same\n superblock, It is unable to reach next superblock because it is gone\n away. We restart scannig superblock from first one, it causes\n unfairness of reclaim unused dentries on first superblock. But I think\n this happens very rarely.\n\n- Test Results\n\n Result on 6GB boxes with excessive unused dentries.\n\nWithout patch:\n\n$ cat /proc/sys/fs/dentry-state\n10181835 10180203 45 0 0 0\n# mount -t nfs 10.124.60.70:/work/kernel-src nfs\nreal 0m1.830s\nuser 0m0.001s\nsys 0m1.653s\n\n With this patch:\n$ cat /proc/sys/fs/dentry-state\n10236610 10234751 45 0 0 0\n# mount -t nfs 10.124.60.70:/work/kernel-src nfs\nreal 0m0.106s\nuser 0m0.002s\nsys 0m0.032s\n\n[akpm@linux-foundation.org: fix comments]\nSigned-off-by: Kentaro Makita \u003ck-makita@np.css.fujitsu.com\u003e\nCc: Neil Brown \u003cneilb@suse.de\u003e\nCc: Trond Myklebust \u003ctrond.myklebust@fys.uio.no\u003e\nCc: David Chinner \u003cdgc@sgi.com\u003e\nCc: \"J.

The\nunderlying value is maintained already as bprm-\u003eexec; setup_arg_pages()\nin fs/exec.c slides it for stack_shift, etc.\n\nSigned-off-by: John Reiser \u003cjreiser@BitWagon.com\u003e\nCc: Roland McGrath \u003croland@redhat.com\u003e\nCc: Jakub Jelinek \u003cjakub@redhat.com\u003e\nCc: Ulrich Drepper \u003cdrepper@redhat.com\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "36ce6dad6e3cb3f050ed41e0beac0070d2062b25", "tree": "91c89c903b06dc8b76e66e7b2341bcd6085e81d0", "parents": [ "0ad1d6f37cc3bb234c6e7ae30e40d1d40b9aa258" ], "author": { "name": "Cornelia Huck", "email": "cornelia.huck@de.ibm.com", "time": "Tue Jun 10 11:09:08 2008 +0200" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@suse.de", "time": "Mon Jul 21 21:55:01 2008 -0700" }, "message": "driver core: Suppress sysfs warnings for device_rename().\n\ndriver core: Suppress sysfs warnings for device_rename().\n\nRenaming network devices to an already existing name is not\nsomething we want sysfs to print a scary warning for, since the\ncallers can deal with this correctly.
