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.

It sets\nDCACHE_AUTOFS_PENDING in the -\u003elookup routine, creates a waitq entry for\n\u0027foo\u0027, and calls out to the daemon to perform the mount. 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. This\nprocess again finds a dentry in the dcache for \u0027foo\u0027, and calls into the\nautofs revalidate code.\n\nThe revalidate code finds that the PENDING flag is set, and so calls\ntry_to_fill_dentry.\n\na) try_to_fill_dentry sets the PENDING flag redundantly for this\n dentry, then calls into the autofs4 wait code.\n\nb) the autofs4 wait code takes the waitq mutex and searches for an\n entry for \u0027foo\u0027\n\nBetween a and b, P1 is woken up because the mount completed. 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. This is\nsimply impossible. Add the third process, though, and it becomes slightly\nmore likely.\n\nSigned-off-by: Jeff Moyer \u003cjmoyer@redhat.com\u003e\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": "5a11d4d0ee1ff284271f7265929d07ea4a1168a6", "tree": "4b9b76486afa5d9fc29216df069c5a557e09011a", "parents": [ "70b52a0a5005ce6a0ceec56e97222437a0ba7506" ], "author": { "name": "Ian Kent", "email": "raven@themaw.net", "time": "Wed Jul 23 21:30:17 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Jul 24 10:47:32 2008 -0700" }, "message": "autofs4: fix waitq locking\n\nThe autofs4_catatonic_mode() function accesses the wait queue without any\nlocking but can be called at any time.

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. This patch\nachieves that by adding the initial dentry to a look aside list and\nremoves it at -\u003emkdir() or -\u003esymlink() completion (or when the dentry is\nreleased), since these are the only create operations autofs4 supports.\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": "caf7da3d5d4d9dd873eb52d025d8cc63b89f1fdb", "tree": "9e53359c28c4247eae9685a5f9c63a5c0a54a7b1", "parents": [ "5f6f4f28b6ba543beef8bad91aa6f69c7ffeee51" ], "author": { "name": "Ian Kent", "email": "raven@themaw.net", "time": "Wed Jul 23 21:30:11 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Jul 24 10:47:31 2008 -0700" }, "message": "autofs4: revert - redo lookup in ttfd\n\nThis patch series enables the use of a single dentry for lookups prior to\nthe dentry being hashed and so we no longer need to redo the lookup.

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.
