This is needed to ensure that the VFS will not race with\noperations on these sub-dirs. This is safe for the following reasons:\n\n- the VFS allows one to lock first an inode and second one of its\n children (The lock subclasses for this pattern are respectively\n I_MUTEX_PARENT and I_MUTEX_CHILD);\n- from this rule any inode path can be recursively locked in\n descending order as long as it stays under a single mountpoint and\n does not follow symlinks.\n\nUnfortunately lockdep does not know (yet?) how to handle such\nrecursion.\n\nI\u0027ve tried to use Peter Zijlstra\u0027s lock_set_subclass() helper to\nupgrade i_mutexes from I_MUTEX_CHILD to I_MUTEX_PARENT when we know\nthat we might recursively lock some of their descendant, but this\nusage does not seem to fit the purpose of lock_set_subclass() because\nit leads to several i_mutex locked with subclass I_MUTEX_PARENT by\nthe same task.\n\n\u003eFrom inside configfs it is not possible to serialize those recursive\nlocking with a top-level one, because mkdir() and rmdir() are already\ncalled with inodes locked by the VFS. So using some\nmutex_lock_nest_lock() is not an option.\n\nI am proposing two solutions:\n1) one that wraps recursive mutex_lock()s with\n lockdep_off()/lockdep_on().\n2) (as suggested earlier by Peter Zijlstra) one that puts the\n i_mutexes recursively locked in different classes based on their\n depth from the top-level config_group created. This\n induces an arbitrary limit (MAX_LOCK_DEPTH - 2 \u003d\u003d 46) on the\n nesting of configfs default groups whenever lockdep is activated\n but this limit looks reasonably high. Unfortunately, this alos\n isolates VFS operations on configfs default groups from the others\n and thus lowers the chances to detect locking issues.\n\nThis patch implements solution 1).\n\nSolution 2) looks better from lockdep\u0027s point of view, but fails with\nconfigfs_depend_item(). This needs to rework the locking\nscheme of configfs_depend_item() by removing the variable lock recursion\ndepth, and I think that it\u0027s doable thanks to the configfs_dirent_lock.\nFor now, let\u0027s stick to solution 1).\n\nSigned-off-by: Louis Rilling \u003clouis.rilling@kerlabs.com\u003e\nAcked-by: Joel Becker \u003cjoel.becker@oracle.com\u003e\nSigned-off-by: Mark Fasheh \u003cmfasheh@suse.com\u003e\n" }, { "commit": "4591dabe27ec0f7928fb73d93694698e21dc769e", "tree": "46e23f750b2bf66f3f77b7cf9cb1ba11d542a2b3", "parents": [ "5f3a211a8b02222498f134ea961fe29c97a4801f" ], "author": { "name": "Alexey Dobriyan", "email": "adobriyan@gmail.com", "time": "Thu Jan 22 10:42:52 2009 +0300" }, "committer": { "name": "Alexey Dobriyan", "email": "adobriyan@gmail.com", "time": "Thu Jan 22 13:15:56 2009 +0300" }, "message": "fs/Kconfig: move configfs out\n\nSigned-off-by: Alexey Dobriyan \u003cadobriyan@gmail.com\u003e\n" }, { "commit": "56ff5efad96182f4d3cb3dc6b07396762c658f16", "tree": "cb91f93aa2324573527165d56d230b606a3111ed", "parents": [ "acfa4380efe77e290d3a96b11cd4c9f24f4fbb18" ], "author": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Tue Dec 09 09:34:39 2008 -0500" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Mon Jan 05 11:54:28 2009 -0500" }, "message": "zero i_uid/i_gid on inode allocation\n\n... and don\u0027t bother in callers.

In the\nprocess of doing that, it also provides infrastructure for keeping track of\nthe number of writers to any given mount.\n\nThis has a number of uses. It allows chroots to have parts of filesystems\nwritable. It will be useful for containers in the future because users may\nhave root inside a container, but should not be allowed to write to\nsomefilesystems. This also replaces patches that vserver has had out of the\ntree for several years.\n\nIt allows security enhancement by making sure that parts of your filesystem\nread-only (such as when you don\u0027t trust your FTP server), when you don\u0027t want\nto have entire new filesystems mounted, or when you want atime selectively\nupdated. I\u0027ve been using the following script to test that the feature is\nworking as desired. It takes a directory and makes a regular bind and a r/o\nbind mount of it.

For most filesystems, this should be done with simple_set_mnt()\nwhich will set the superblock pointer and then set the root dentry to the\nsuperblock\u0027s s_root (as per the old default behaviour).\n\nThe get_sb() op now returns an integer as there\u0027s now no need to return the\nsuperblock pointer.\n\nThis patch permits a superblock to be implicitly shared amongst several mount\npoints, such as can be done with NFS to avoid potential inode aliasing. In\nsuch a case, simple_set_mnt() would not be called, and instead the mnt_root\nand mnt_sb would be set directly.\n\nThe patch also makes the following changes:\n\n (*) the get_sb_*() convenience functions in the core kernel now take a vfsmount\n pointer argument and return an integer, so most filesystems have to change\n very little.\n\n (*) If one of the convenience function is not used, then get_sb() should\n normally call simple_set_mnt() to instantiate the vfsmount. This will\n always return 0, and so can be tail-called from get_sb().\n\n (*) generic_shutdown_super() now calls shrink_dcache_sb() to clean up the\n dcache upon superblock destruction rather than shrink_dcache_anon().\n\n This is required because the superblock may now have multiple trees that\n aren\u0027t actually bound to s_root, but that still need to be cleaned up. The\n currently called functions assume that the whole tree is rooted at s_root,\n and that anonymous dentries are not the roots of trees which results in\n dentries being left unculled.\n\n However, with the way NFS superblock sharing are currently set to be\n implemented, these assumptions are violated: the root of the filesystem is\n simply a dummy dentry and inode (the real inode for \u0027/\u0027 may well be\n inaccessible), and all the vfsmounts are rooted on anonymous[*] dentries\n with child trees.\n\n [*] Anonymous until discovered from another tree.\n\n (*) The documentation has been adjusted, including the additional bit of\n changing ext2_* into foo_* in the documentation.\n\n[akpm@osdl.org: convert ipath_fs, do other stuff]\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nAcked-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: Nathan Scott \u003cnathans@sgi.com\u003e\nCc: Roland Dreier \u003crolandd@cisco.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "1f5ce9e93aa96a867f195ed45f6f77935175f12e", "tree": "caa9b6635990f69d47c1729524bd127e968b23f5", "parents": [ "bb4a58bf46473e3e83d84054bbc110db3a0f85e4" ], "author": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Fri Jun 09 09:34:16 2006 -0400" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Fri Jun 09 09:34:16 2006 -0400" }, "message": "VFS: Unexport do_kern_mount() and clean up simple_pin_fs()\n\nReplace all module uses with the new vfs_kern_mount() interface, and fix up\nsimple_pin_fs().\n\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "c6a756795d5ba0637aae8da89dd11bb7e3a1ee74", "tree": "1c19f951f2604dbb6b867a6dcdf94d20c204cc5c", "parents": [ "382066da251132f768380f4852ed5afb72d88f80", "a8bd60705aa17a998516837d9c1e503ad4cbd7fc" ], "author": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Thu May 25 12:40:08 2006 -0400" }, "committer": { "name": "Steven Whitehouse", "email": "swhiteho@redhat.com", "time": "Thu May 25 12:40:08 2006 -0400" }, "message": "Merge branch \u0027master\u0027\n" }, { "commit": "eed7a0db460595b139428d252798a83f1e1ce1d3", "tree": "129db180cb8bac9810b6168802914c5ae2f619a3", "parents": [ "84efad1a53dd05969094f9a2562b4e6666571c00" ], "author": { "name": "Joel Becker", "email": "joel.becker@oracle.com", "time": "Tue Apr 11 21:37:20 2006 -0700" }, "committer": { "name": "Mark Fasheh", "email": "mark.fasheh@oracle.com", "time": "Wed May 17 14:38:51 2006 -0700" }, "message": "configfs: configfs_mkdir() failed to cleanup linkage.\n\nIf configfs_mkdir() errored in certain ways after the parent\u003c-\u003echild\nlinkage was already created, it would not undo the linkage.
