And they\nwere confused: it\u0027s not actually a generic 64-bit issue at all, it\u0027s\nvery much tied to just x86-64, which has different alignment for an\n\u0027u64\u0027 in 64-bit mode than in 32-bit mode.\n\nBut the end result is that fixing the compat layer actually breaks the\ncase of a 32-bit automount on a x86-64 kernel.\n\nThere are various approaches to fix this (including just doing a\n\"strcmp()\" on current-\u003ecomm and comparing it to \"automount\"), but I\nthink that I will do the one that teaches pipes about a special \"packet\nmode\", which will allow user space to not have to care too deeply about\nthe padding at the end of the autofs packet.\n\nThat change will make the compat workaround unnecessary, so let\u0027s revert\nit first, and get automount working again in compat mode. The\npacketized pipes will then fix autofs for systemd.\n\nReported-and-requested-by: Michael Tokarev \u003cmjt@tls.msk.ru\u003e\nCc: Ian Kent \u003craven@themaw.net\u003e\nCc: stable@kernel.org # for 3.3\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "a32744d4abae24572eff7269bc17895c41bd0085", "tree": "b384f580af75b17ede3fd830b7ad5276d0036ac0", "parents": [ "b52b80023f262ce8a0ffdcb490acb23e8678377a" ], "author": { "name": "Ian Kent", "email": "raven@themaw.net", "time": "Wed Feb 22 20:45:44 2012 +0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Feb 25 12:10:27 2012 -0800" }, "message": "autofs: work around unhappy compat problem on x86-64\n\nWhen the autofs protocol version 5 packet type was added in commit\n5c0a32fc2cd0 (\"autofs4: add new packet type for v5 communications\"), it\nobvously tried quite hard to be word-size agnostic, and uses explicitly\nsized fields that are all correctly aligned.\n\nHowever, with the final \"char name[NAME_MAX+1]\" array at the end, the\nactual size of the structure ends up being not very well defined:\nbecause the struct isn\u0027t marked \u0027packed\u0027, doing a \"sizeof()\" on it will\nalign the size of the struct up to the biggest alignment of the members\nit has.\n\nAnd despite all the members being the same, the alignment of them is\ndifferent: a \"__u64\" has 4-byte alignment on x86-32, but native 8-byte\nalignment on x86-64. And while \u0027NAME_MAX+1\u0027 ends up being a nice round\nnumber (256), the name[] array starts out a 4-byte aligned.\n\nEnd result: the \"packed\" size of the structure is 300 bytes: 4-byte, but\nnot 8-byte aligned.\n\nAs a result, despite all the fields being in the same place on all\narchitectures, sizeof() will round up that size to 304 bytes on\narchitectures that have 8-byte alignment for u64.\n\nNote that this is *not* a problem for 32-bit compat mode on POWER, since\nthere __u64 is 8-byte aligned even in 32-bit mode. But on x86, 32-bit\nand 64-bit alignment is different for 64-bit entities, and as a result\nthe structure that has exactly the same layout has different sizes.\n\nSo on x86-64, but no other architecture, we will just subtract 4 from\nthe size of the structure when running in a compat task. That way we\nwill write the properly sized packet that user mode expects.\n\nNot pretty. Sadly, this very subtle, and unnecessary, size difference\nhas been encoded in user space that wants to read packets of *exactly*\nthe right size, and will refuse to touch anything else.\n\nReported-and-tested-by: Thomas Meyer \u003cthomas@m3y3r.de\u003e\nSigned-off-by: Ian Kent \u003craven@themaw.net\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "8638094e956a47dbb9a25166705a91e9a0981d52", "tree": "c776b8254bb1a070cfafe5be8615c25b1314e31a", "parents": [ "099469502f62fbe0d7e4f0b83a2f22538367f734" ], "author": { "name": "Ian Kent", "email": "raven@themaw.net", "time": "Fri Jan 13 20:41:46 2012 +0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Jan 13 08:30:49 2012 -0800" }, "message": "autofs4 - fix deal with autofs4_write races\n\nI don\u0027t know how I missed this obvious mistake when I\nreviewed Als\u0027 patches, sorry.\n\n[ Quoting Al:\n\n\tGrr...

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.

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.
