According to a git\nbisect search, the problem was introduced with the VM_MIXEDMAP/PTE_SPECIAL\nrework in the vm:\n\ncommit 70688e4dd1647f0ceb502bbd5964fa344c5eb411\nAuthor: Nick Piggin \u003cnpiggin@suse.de\u003e\nDate: Mon Apr 28 02:13:02 2008 -0700\n\n xip: support non-struct page backed memory\n\nIn the failing scenario, the filesystem is mounted read only via root\u003d\nkernel parameter on s390x. During remount (in rc.sysinit), the inodes of\nthe bash binary and its libraries are busy and cannot be invalidated (the\nbash which is running rc.sysinit resides on subject filesystem).\nAfterwards, another bash process (running ifup-eth) recurses into a\nsubshell, runs dup_mm (via fork). Some of the mappings in this bash\nprocess were created from inodes that could not be invalidated during\nremount.\n\nBoth parent and child process crash some time later due to inconsistencies\nin their address spaces. The issue seems to be timing sensitive, various\nattempts to recreate it have failed.\n\nThis patch refuses to change the xip flag during remount in case some\ninodes cannot be invalidated. This patch keeps users from running into\nthat issue.\n\n[akpm@linux-foundation.org: cleanup]\nSigned-off-by: Carsten Otte \u003ccotte@de.ibm.com\u003e\nCc: Nick Piggin \u003cnpiggin@suse.de\u003e\nCc: Jared Hulbert \u003cjaredeh@gmail.com\u003e\nCc: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nCc: Heiko Carstens \u003cheiko.carstens@de.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "02ac597c9b86af49b2016aa98aee20ab59dbf0d2", "tree": "7ecf4acd955eabb023dba50c0b4ef67d585eb56e", "parents": [ "8fe4cd0dc5ea43760c59eb256404188272cc95dd" ], "author": { "name": "Jan Kara", "email": "jack@suse.cz", "time": "Wed Feb 11 13:04:26 2009 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Feb 11 14:25:35 2009 -0800" }, "message": "ext3: revert \"ext3: wait on all pending commits in ext3_sync_fs\"\n\nThis reverts commit c87591b719737b4e91eb1a9fa8fd55a4ff1886d6.\n\nSince journal_start_commit() is now fixed to return 1 when we started a\ntransaction commit, there\u0027s some transaction waiting to be committed or\nthere\u0027s a transaction already committing, we don\u0027t need to call\next3_force_commit() in ext3_sync_fs().

This flag is set if any of the usage counts for\nfs_struct, files_struct and sighand_struct are greater than 1 at the time the\ndetermination is made. All of which are true for threads created by the\npthread library.\n\nHowever, since we wish to make the security calculation before irrevocably\ndamaging the process so that we can return it an error code in the case where\nwe decide we want to reject the exec request on this basis, we have to make the\ndetermination before calling de_thread().\n\nSo, instead, we count up the number of threads (CLONE_THREAD) that are sharing\nour fs_struct (CLONE_FS), files_struct (CLONE_FILES) and sighand_structs\n(CLONE_SIGHAND/CLONE_THREAD) with us. These will be killed by de_thread() and\nso can be discounted by check_unsafe_exec().\n\nWe do have to be careful because CLONE_THREAD does not imply FS or FILES.\n\nWe _assume_ that there will be no extra references to these structs held by the\nthreads we\u0027re going to kill.\n\nThis can be tested with the attached pair of programs. Build the two programs\nusing the Makefile supplied, and run ./test1 as a non-root user.

Snapshot deletion\nworks by walking down the btree and dropping the reference counts\non each btree block during the walk.\n\nIf if a given leaf or node has a reference count greater than one,\nthe reference count is decremented and the subtree pointed to by that\nnode is ignored.\n\nIf the reference count is one, walking continues down into that node\nor leaf, and the references of everything it points to are decremented.\n\nThe old code would try to work in small pieces, walking down the tree\nuntil it found the lowest leaf or node to free and then returning. This\nwas very friendly to the rest of the FS because it didn\u0027t have a huge\nimpact on other operations.\n\nBut it wouldn\u0027t always keep up with the rate that new commits added new\nsnapshots for deletion, and it wasn\u0027t very optimal for the extent\nallocation tree because it wasn\u0027t finding leaves that were close together\non disk and processing them at the same time.\n\nThis changes things to walk down to a level 1 node and then process it\nin bulk. All the leaf pointers are sorted and the leaves are dropped\nin order based on their extent number.\n\nThe extent allocation tree and commit code are now fast enough for\nthis kind of bulk processing to work without slowing the rest of the FS\ndown.

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": "f8afead7169f0f28a4b421bcbdb510e52a2d094d", "tree": "83245132376808a9a03868b6beb28d66e1f2a8fa", "parents": [ "ea455f8ab68338ba69f5d3362b342c115bea8e13" ], "author": { "name": "Jan Kara", "email": "jack@suse.cz", "time": "Mon Jan 12 23:20:32 2009 +0100" }, "committer": { "name": "Mark Fasheh", "email": "mfasheh@suse.com", "time": "Mon Feb 02 14:20:17 2009 -0800" }, "message": "ocfs2: Fix possible deadlock in ocfs2_write_dquot()\n\nIt could happen that some limit has been set via quotactl() and in parallel\n-\u003emark_dirty() is called from another thread doing e.g. dquot_alloc_space().

or freeing.\n\u003e\n\u003e So if the code is written in this way, it may still be buggy, but at least\n\u003e it\u0027s not buggy because of subtle \"forgot to unlock\" or \"forgot to free\"\n\u003e
