      "message": "vfs pathname lookup: Add LOOKUP_AUTOMOUNT flag\n\nSince we\u0027ve now turned around and made LOOKUP_FOLLOW *not* force an\nautomount, we want to add the ability to force an automount event on\nlookup even if we don\u0027t happen to have one of the other flags that force\nit implicitly (LOOKUP_OPEN, LOOKUP_DIRECTORY, LOOKUP_PARENT..)\n\nMost cases will never want to use this, since you\u0027d normally want to\ndelay automounting as long as possible, which usually implies\nLOOKUP_OPEN (when we open a file or directory, we really cannot avoid\nthe automount any more).\n\nBut Trond argued sufficiently forcefully that at a minimum bind mounting\na file and quotactl will want to force the automount lookup.  Some other\ncases (like nfs_follow_remote_path()) could use it too, although\nLOOKUP_DIRECTORY would work there as well.\n\nThis commit just adds the flag and logic, no users yet, though.  It also\ndoesn\u0027t actually touch the LOOKUP_NO_AUTOMOUNT flag that is related, and\nwas made irrelevant by the same change that made us not follow on\nLOOKUP_FOLLOW.\n\nCc: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\nCc: Ian Kent \u003craven@themaw.net\u003e\nCc: Jeff Layton \u003cjlayton@redhat.com\u003e\nCc: Miklos Szeredi \u003cmiklos@szeredi.hu\u003e\nCc: David Howells \u003cdhowells@redhat.com\u003e\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: Greg KH \u003cgregkh@suse.de\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

This will allow autofs to hold up client processes whilst letting\nits userspace daemon through to maintain the directory or the stuff behind it\nor mounted upon it.\n\nThe -\u003ed_manage() dentry operation:\n\n\tint (*d_manage)(struct path *path, bool mounting_here);\n\ntakes a pointer to the directory about to be transited away from and a flag\nindicating whether the transit is undertaken by do_add_mount() or\ndo_move_mount() skipping through a pile of filesystems mounted on a mountpoint.\n\nIt should return 0 if successful and to let the process continue on its way;\n-EISDIR to prohibit the caller from skipping to overmounted filesystems or\nautomounting, and to use this directory; or some other error code to return to\nthe user.\n\n-\u003ed_manage() is called with namespace_sem writelocked if mounting_here is true\nand no other locks held, so it may sleep.  However, if mounting_here is true,\nit may not initiate or wait for a mount or unmount upon the parameter\ndirectory, even if the act is actually performed by userspace.\n\nWithin fs/namei.c, follow_managed() is extended to check with d_manage() first\non each managed directory, before transiting away from it or attempting to\nautomount upon it.\n\nfollow_down() is renamed follow_down_one() and should only be used where the\nfilesystem deliberately intends to avoid management steps (e.g. autofs).\n\nA new follow_down() is added that incorporates the loop done by all other\ncallers of follow_down() (do_add/move_mount(), autofs and NFSD; whilst AFS, NFS\nand CIFS do use it, their use is removed by converting them to use\nd_automount()).  The new follow_down() calls d_manage() as appropriate.  It\nalso takes an extra parameter to indicate if it is being called from mount code\n(with namespace_sem writelocked) which it passes to d_manage().  follow_down()\nignores automount points so that it can be used to mount on them.\n\n__follow_mount_rcu() is made to abort rcu-walk mode if it hits a directory with\nDCACHE_MANAGE_TRANSIT set on the basis that we\u0027re probably going to have to\nsleep.  It would be possible to enter d_manage() in rcu-walk mode too, and have\nthat determine whether to abort or not itself.  That would allow the autofs\ndaemon to continue on in rcu-walk mode.\n\nNote that DCACHE_MANAGE_TRANSIT on a directory should be cleared when it isn\u0027t\nrequired as every tranist from that directory will cause d_manage() to be\ninvoked.  It can always be set again when necessary.\n\n\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\nWHAT THIS MEANS FOR AUTOFS\n\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\n\nAutofs currently uses the lookup() inode op and the d_revalidate() dentry op to\ntrigger the automounting of indirect mounts, and both of these can be called\nwith i_mutex held.\n\nautofs knows that the i_mutex will be held by the caller in lookup(), and so\ncan drop it before invoking the daemon - but this isn\u0027t so for d_revalidate(),\nsince the lock is only held on _some_ of the code paths that call it.  This\nmeans that autofs can\u0027t risk dropping i_mutex from its d_revalidate() function\nbefore it calls the daemon.\n\nThe bug could manifest itself as, for example, a process that\u0027s trying to\nvalidate an automount dentry that gets made to wait because that dentry is\nexpired and needs cleaning up:\n\n\tmkdir         S ffffffff8014e05a     0 32580  24956\n\tCall Trace:\n\t [\u003cffffffff885371fd\u003e] :autofs4:autofs4_wait+0x674/0x897\n\t [\u003cffffffff80127f7d\u003e] avc_has_perm+0x46/0x58\n\t [\u003cffffffff8009fdcf\u003e] autoremove_wake_function+0x0/0x2e\n\t [\u003cffffffff88537be6\u003e] :autofs4:autofs4_expire_wait+0x41/0x6b\n\t [\u003cffffffff88535cfc\u003e] :autofs4:autofs4_revalidate+0x91/0x149\n\t [\u003cffffffff80036d96\u003e] __lookup_hash+0xa0/0x12f\n\t [\u003cffffffff80057a2f\u003e] lookup_create+0x46/0x80\n\t [\u003cffffffff800e6e31\u003e] sys_mkdirat+0x56/0xe4\n\nversus the automount daemon which wants to remove that dentry, but can\u0027t\nbecause the normal process is holding the i_mutex lock:\n\n\tautomount     D ffffffff8014e05a     0 32581      1              32561\n\tCall Trace:\n\t [\u003cffffffff80063c3f\u003e] __mutex_lock_slowpath+0x60/0x9b\n\t [\u003cffffffff8000ccf1\u003e] do_path_lookup+0x2ca/0x2f1\n\t [\u003cffffffff80063c89\u003e] .text.lock.mutex+0xf/0x14\n\t [\u003cffffffff800e6d55\u003e] do_rmdir+0x77/0xde\n\t [\u003cffffffff8005d229\u003e] tracesys+0x71/0xe0\n\t [\u003cffffffff8005d28d\u003e] tracesys+0xd5/0xe0\n\nwhich means that the system is deadlocked.\n\nThis patch allows autofs to hold up normal processes whilst the daemon goes\nahead and does things to the dentry tree behind the automouter point without\nrisking a deadlock as almost no locks are held in d_manage() and none in\nd_automount().\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nWas-Acked-by: Ian Kent \u003craven@themaw.net\u003e\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n"

      "message": "fs: rcu-walk for path lookup\n\nPerform common cases of path lookups without any stores or locking in the\nancestor dentry elements. This is called rcu-walk, as opposed to the current\nalgorithm which is a refcount based walk, or ref-walk.\n\nThis results in far fewer atomic operations on every path element,\nsignificantly improving path lookup performance. It also avoids cacheline\nbouncing on common dentries, significantly improving scalability.\n\nThe overall design is like this:\n* LOOKUP_RCU is set in nd-\u003eflags, which distinguishes rcu-walk from ref-walk.\n* Take the RCU lock for the entire path walk, starting with the acquiring\n  of the starting path (eg. root/cwd/fd-path). So now dentry refcounts are\n  not required for dentry persistence.\n* synchronize_rcu is called when unregistering a filesystem, so we can\n  access d_ops and i_ops during rcu-walk.\n* Similarly take the vfsmount lock for the entire path walk. So now mnt\n  refcounts are not required for persistence. Also we are free to perform mount\n  lookups, and to assume dentry mount points and mount roots are stable up and\n  down the path.\n* Have a per-dentry seqlock to protect the dentry name, parent, and inode,\n  so we can load this tuple atomically, and also check whether any of its\n  members have changed.\n* Dentry lookups (based on parent, candidate string tuple) recheck the parent\n  sequence after the child is found in case anything changed in the parent\n  during the path walk.\n* inode is also RCU protected so we can load d_inode and use the inode for\n  limited things.\n* i_mode, i_uid, i_gid can be tested for exec permissions during path walk.\n* i_op can be loaded.\n\nWhen we reach the destination dentry, we lock it, recheck lookup sequence,\nand increment its refcount and mountpoint refcount. RCU and vfsmount locks\nare dropped. This is termed \"dropping rcu-walk\". If the dentry refcount does\nnot match, we can not drop rcu-walk gracefully at the current point in the\nlokup, so instead return -ECHILD (for want of a better errno). This signals the\npath walking code to re-do the entire lookup with a ref-walk.\n\nAside from the final dentry, there are other situations that may be encounted\nwhere we cannot continue rcu-walk. In that case, we drop rcu-walk (ie. take\na reference on the last good dentry) and continue with a ref-walk. Again, if\nwe can drop rcu-walk gracefully, we return -ECHILD and do the whole lookup\nusing ref-walk. But it is very important that we can continue with ref-walk\nfor most cases, particularly to avoid the overhead of double lookups, and to\ngain the scalability advantages on common path elements (like cwd and root).\n\nThe cases where rcu-walk cannot continue are:\n* NULL dentry (ie. any uncached path element)\n* parent with d_inode-\u003ei_op-\u003epermission or ACLs\n* dentries with d_revalidate\n* Following links\n\nIn future patches, permission checks and d_revalidate become rcu-walk aware. It\nmay be possible eventually to make following links rcu-walk aware.\n\nUncached path elements will always require dropping to ref-walk mode, at the\nvery least because i_mutex needs to be grabbed, and objects allocated.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@kernel.dk\u003e\n"

      "message": "fs: introduce vfs_path_lookup\n\nStackable file systems, among others, frequently need to lookup paths or\npath components starting from an arbitrary point in the namespace\n(identified by a dentry and a vfsmount).  Currently, such file systems use\nlookup_one_len, which is frowned upon [1] as it does not pass the lookup\nintent along; not passing a lookup intent, for example, can trigger BUG_ON\u0027s\nwhen stacking on top of NFSv4.\n\nThe first patch introduces a new lookup function to allow lookup starting\nfrom an arbitrary point in the namespace.  This approach has been suggested\nby Christoph Hellwig [2].\n\nThe second patch changes sunrpc to use vfs_path_lookup.\n\nThe third patch changes nfsctl.c to use vfs_path_lookup.\n\nThe fourth patch marks link_path_walk static.\n\nThe fifth, and last patch, unexports path_walk because it is no longer\nunnecessary to call it directly, and using the new vfs_path_lookup is\ncleaner.\n\nFor example, the following snippet of code, looks up \"some/path/component\"\nin a directory pointed to by parent_{dentry,vfsmnt}:\n\nerr \u003d vfs_path_lookup(parent_dentry, parent_vfsmnt,\n\t\t      \"some/path/component\", 0, \u0026nd);\nif (!err) {\n\t/* exits */\n\n\t...\n\n\t/* once done, release the references */\n\tpath_release(\u0026nd);\n} else if (err \u003d\u003d -ENOENT) {\n\t/* doesn\u0027t exist */\n} else {\n\t/* other error */\n}\n\nVFS functions such as lookup_create can be used on the nameidata structure\nto pass the create intent to the file system.\n\nSigned-off-by: Josef \u0027Jeff\u0027 Sipek \u003cjsipek@cs.sunysb.edu\u003e\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nAcked-by: Christoph Hellwig \u003chch@lst.de\u003e\nCc: Trond Myklebust \u003ctrond.myklebust@fys.uio.no\u003e\nCc: Neil Brown \u003cneilb@suse.de\u003e\nCc: Michael Halcrow \u003cmhalcrow@us.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

These functions, openat etc, have been discussed on numerous\noccasions.  They are needed to implement race-free filesystem traversal,\nthey are necessary to implement a virtual per-thread current working\ndirectory (think multi-threaded backup software), etc.\n\nWe have in glibc today implementations of the interfaces which use the\n/proc/self/fd magic.  But this code is rather expensive.  Here are some\nresults (similar to what Jim Meyering posted before).\n\nThe test creates a deep directory hierarchy on a tmpfs filesystem.  Then\nrm -fr is used to remove all directories.  Without syscall support I get\nthis:\n\nreal    0m31.921s\nuser    0m0.688s\nsys     0m31.234s\n\nWith syscall support the results are much better:\n\nreal    0m20.699s\nuser    0m0.536s\nsys     0m20.149s\n\nThe interfaces are for obvious reasons currently not much used.  But they\u0027ll\nbe used.  coreutils (and Jeff\u0027s posixutils) are already using them.\nFurthermore, code like ftw/fts in libc (maybe even glob) will also start using\nthem.
