At one point, a patch I seriously considered applying\nfrom Michael Tokarev did a \"strcmp()\" to see if it was automount that\nwas doing the operation. Ugly, ugly.\n\nHowever, a prettier solution exists now thanks to the packetized pipe\nmode. By marking the communication pipe as being packetized (by simply\nsetting the O_DIRECT flag), we can always just write the bigger packet\nsize, and if user-space does a smaller read, it will just get that\npartial end result and the extra alignment padding will simply be thrown\naway.\n\nThis makes both automount and systemd happy, since they now get the size\nthey asked for, and the kernel side of autofs simply no longer needs to\ncare - it could pad out the packet arbitrarily.\n\nOf course, if there is some *other* user of autofs (please, please,\nplease tell me it ain\u0027t so - and we haven\u0027t heard of any) that tries to\nread the packets with multiple writes, that other user will now be\nbroken - the whole point of the packetized mode is that one system call\ngets exactly one packet, and you cannot read a packet in pieces.\n\nTested-by: Michael Tokarev \u003cmjt@tls.msk.ru\u003e\nCc: Alan Cox \u003calan@lxorguk.ukuu.org.uk\u003e\nCc: David Miller \u003cdavem@davemloft.net\u003e\nCc: Ian Kent \u003craven@themaw.net\u003e\nCc: Thomas Meyer \u003cthomas@m3y3r.de\u003e\nCc: stable@kernel.org\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "fcbf94b9dedd2ce08e798a99aafc94fec8668161", "tree": "bc81982bbcf96538a09103b2c722ac7d2c99bdef", "parents": [ "c629eaf8392b676b4f83c3dc344e66402bfeec92" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Apr 28 08:29:56 2012 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Apr 28 08:29:56 2012 -0700" }, "message": "Revert \"autofs: work around unhappy compat problem on x86-64\"\n\nThis reverts commit a32744d4abae24572eff7269bc17895c41bd0085.\n\nWhile that commit was technically the right thing to do, and made the\nx86-64 compat mode work identically to native 32-bit mode (and thus\nfixing the problem with a 32-bit systemd install on a 64-bit kernel), it\nturns out that the automount binaries had workarounds for this compat\nproblem.\n\nNow, the workarounds are disgusting: doing an \"uname()\" to find out the\narchitecture of the kernel, and then comparing it for the 64-bit cases\nand fixing up the size of the read() in automount for those. 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.

This delayed the hashing of lookup dentrys until the -\u003emkdir()\n(or -\u003esymlink()) operation completed to ensure we always went through\n-\u003elookup() instead of also having processes go through -\u003erevalidate() so\nour VFS locking remained consistent.\n\nNow we are seeing a couple of side affects of that change in situations\nwith heavy mount activity.\n\nTwo cases have been identified:\n\n1) When a mount request is triggered, due to the delayed hashing, the\n directory created by user space for the mount point doesn\u0027t have the\n DCACHE_AUTOFS_PENDING flag set. 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": "5f6f4f28b6ba543beef8bad91aa6f69c7ffeee51", "tree": "72f3aac56d49c7bea7940f8d8b6e8ca559e3ae1c", "parents": [ "391b52f98cf2e9bff227dad8bf9ea206fec43fa4" ], "author": { "name": "Ian Kent", "email": "raven@themaw.net", "time": "Wed Jul 23 21:30:09 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Jul 24 10:47:31 2008 -0700" }, "message": "autofs4: don\u0027t make expiring dentry negative\n\nCorrect the error of making a positive dentry negative after it has been\ninstantiated.\n\nThe code that makes this error attempts to re-use the dentry from a\nconcurrent expire and mount to resolve a race and the dentry used for the\nlookup must be negative for mounts to trigger in the required cases.
