The operation is keyed off a new dentry flag\n(DCACHE_MANAGE_TRANSIT).\n\nThe filesystem is allowed to be selective about which processes it holds and\nwhich it permits to continue on or prohibits from transiting from each flagged\ndirectory. 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.

For cases where we can we can automatically prove that\nthe file offset is always ignored, we use noop_llseek, which maintains\nthe current behavior of not returning an error from a seek.\n\nNew drivers should normally not use noop_llseek but instead use no_llseek\nand call nonseekable_open at open time.

Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability. As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n only the necessary includes are there. ie. if only gfp is used,\n gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n blocks and try to put the new include such that its order conforms\n to its surrounding. It\u0027s put in the include block which contains\n core kernel includes, in the same order that the rest are ordered -\n alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n because the file doesn\u0027t have fitting include block), it prints out\n an error message indicating which .h file needs to be added to the\n file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n and ~3000 slab.h inclusions. The script emitted errors for ~400\n files.\n\n2. Each error was manually checked. Some didn\u0027t need the inclusion,\n some needed manual addition while adding it to implementation .h or\n embedding .c file was more appropriate for others. This step added\n inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n editing them as sprinkling gfp.h and slab.h inclusions around .h\n files could easily lead to inclusion dependency hell. Most gfp.h\n inclusion directives were ignored as stuff from gfp.h was usually\n wildly available and often used in preprocessor macros. Each\n slab.h inclusion directive was examined and added manually as\n necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7. Build test were done on the following configurations and failures\n were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my\n distributed build env didn\u0027t work with gcov compiles) and a few\n more options had to be turned off depending on archs to make things\n build (like ipr on powerpc/64 which failed due to missing writeq).\n\n * x86 and x86_64 UP and SMP allmodconfig and a custom test config.\n * powerpc and powerpc64 SMP allmodconfig\n * sparc and sparc64 SMP allmodconfig\n * ia64 SMP allmodconfig\n * s390 SMP allmodconfig\n * alpha SMP allmodconfig\n * um on x86_64 SMP allmodconfig\n\n8. percpu.h modifications were reverted so that it could be applied as\n a separate patch and serve as bisection point.\n\nGiven the fact that I had only a couple of failures from tests on step\n6, I\u0027m fairly confident about the coverage of this conversion patch.\nIf there is a breakage, it\u0027s likely to be something in one of the arch\nheaders which should be easily discoverable easily on most builds of\nthe specific arch.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nGuess-its-ok-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\n" }, { "commit": "99b437a9257cb6b267bf32adfb7675948dc6d485", "tree": "21173f7d22026bf37455cc7baa32e71acff82e8c", "parents": [ "45575f5a426c01ec68cd33d998267ba2f6278fac" ], "author": { "name": "Dan Carpenter", "email": "error27@gmail.com", "time": "Mon Mar 22 13:07:14 2010 +0000" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Mar 22 09:57:19 2010 -0700" }, "message": "AFS: Potential null dereference\n\nIt seems clear from the surrounding code that xpermits is allowed to be\nNULL here.\n\nSigned-off-by: Dan Carpenter \u003cerror27@gmail.com\u003e\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "26821ed40b4230259e770c9911180f38fcaa6f59", "tree": "40cd0fed705ec59dd3c909b96452bae1fc532796", "parents": [ "64ba9926759792cf7b95f823402e2781edd1b5d4" ], "author": { "name": "Christoph Hellwig", "email": "hch@lst.de", "time": "Fri Mar 05 09:21:21 2010 +0100" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Fri Mar 05 13:25:10 2010 -0500" }, "message": "make sure data is on disk before calling -\u003ewrite_inode\n\nSimilar to the fsync issue fixed a while ago in commit\n2daea67e966dc0c42067ebea015ddac6834cef88 we need to write for data to\nactually hit the disk before writing out the metadata to guarantee\ndata integrity for filesystems that modify the inode in the data I/O\ncompletion path.

This patch intends to actually give us real O_SYNC\nsemantics in addition to the O_DSYNC semantics. After Jan\u0027s O_SYNC\npatches which are required before this patch it\u0027s actually surprisingly\nsimple, we just need to figure out when to set the datasync flag to\nvfs_fsync_range and when not.\n\nThis patch renames the existing O_SYNC flag to O_DSYNC while keeping it\u0027s\nnumerical value to keep binary compatibility, and adds a new real O_SYNC\nflag. To guarantee backwards compatiblity it is defined as expanding to\nboth the O_DSYNC and the new additional binary flag (__O_SYNC) to make\nsure we are backwards-compatible when compiled against the new headers.\n\nThis also means that all places that don\u0027t care about the differences can\njust check O_DSYNC and get the right behaviour for O_SYNC, too - only\nplaces that actuall care need to check __O_SYNC in addition. Drivers and\nnetwork filesystems have been updated in a fail safe way to always do the\nfull sync magic if O_DSYNC is set. The few places setting O_SYNC for\nlower layers are kept that way for now to stay failsafe.\n\nWe enforce that O_DSYNC is set when __O_SYNC is set early in the open path\nto make sure we always get these sane options.\n\nNote that parisc really screwed up their headers as they already define a\nO_DSYNC that has always been a no-op.

This means that some data won\u0027t make it into the\ncache this time. To support this, a new FS-Cache function is added\nfscache_maybe_release_page() that replaces what the netfs releasepage()\nfunctions used to do with respect to the cache.\n\nThe decisions fscache_maybe_release_page() makes are counted and displayed\nthrough /proc/fs/fscache/stats on a line labelled \"VmScan\". There are four\ncounters provided: \"nos\u003dN\" - pages that weren\u0027t pending storage; \"gon\u003dN\" -\npages that were pending storage when we first looked, but weren\u0027t by the time\nwe got the object lock; \"bsy\u003dN\" - pages that we ignored as they were actively\nbeing written when we looked; and \"can\u003dN\" - pages that we cancelled the storage\nof.\n\nWhat I\u0027d really like to do is alter the behaviour of the cancellation\nheuristics, depending on how necessary it is to expel pages. If there are\nplenty of other pages that aren\u0027t waiting to be written to the cache that\ncould be ejected first, then it would be nice to hold up on immediate\ncancellation of cache writes - but I don\u0027t see a way of doing that.\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\n" }, { "commit": "80e50be4220e1244fcf6d5f75b997f8586ae1300", "tree": "29045a3bbfd165dae5096c3c884e2c2a87f0933f", "parents": [ "8fccae2c95506270f74ee8429c273b0924e89c83" ], "author": { "name": "Christoph Hellwig", "email": "hch@lst.de", "time": "Thu Oct 01 15:44:27 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Oct 01 16:11:16 2009 -0700" }, "message": "afs: remove cache.h\n\nIt\u0027s just a wrapper for \u003clinux/fscache.h\u003e, so remove it.\n\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\nSigned-off-by: David Howells \u003cdhowells@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": "88e9d34c727883d7d6f02cf1475b3ec98b8480c7", "tree": "475f544536d52739e0929e7727cab5124e855a06", "parents": [ "b7ed698cc9d556306a4088c238e2ea9311ea2cb3" ], "author": { "name": "James Morris", "email": "jmorris@namei.org", "time": "Tue Sep 22 16:43:43 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Sep 23 07:39:29 2009 -0700" }, "message": "seq_file: constify seq_operations\n\nMake all seq_operations structs const, to help mitigate against\nrevectoring user-triggerable function pointers.\n\nThis is derived from the grsecurity patch, although generated from scratch\nbecause it\u0027s simpler than extracting the changes from there.\n\nSigned-off-by: James Morris \u003cjmorris@namei.org\u003e\nAcked-by: Serge Hallyn \u003cserue@us.ibm.com\u003e\nAcked-by: Casey Schaufler \u003ccasey@schaufler-ca.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "6aed62853c72e29f2c97bbac7712cb398e8c9437", "tree": "4362cfa98b6b588f84fb2241115b7ef5b5dfce55", "parents": [ "6e1d5dcc2bbbe71dbf010c747e15739bef6b7218" ], "author": { "name": "Alexey Dobriyan", "email": "adobriyan@gmail.com", "time": "Mon Sep 21 17:01:11 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Sep 22 07:17:25 2009 -0700" }, "message": "const: make file_lock_operations const\n\nSigned-off-by: Alexey Dobriyan \u003cadobriyan@gmail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "1fe06ad89255c211fe100d7f690d10b161398df8", "tree": "826d32bf081a6729aeaa08fe42422e49a9b86f6f", "parents": [ "2c96ce9f2084c1e04d02883e622f74a537a63aea" ], "author": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Tue Sep 15 15:10:20 2009 +0200" }, "committer": { "name": "Jens Axboe", "email": "jens.axboe@oracle.com", "time": "Wed Sep 16 15:16:18 2009 +0200" }, "message": "writeback: get rid of wbc-\u003efor_writepages\n\nIt\u0027s only set, it\u0027s never checked.

They are done in write_begin, which would always\nassume that the filesystem can be entered from reclaim. This bug could\ncause filesystem deadlocks.\n\nThe funny thing with having a gfp_t mask there is that it doesn\u0027t really\nallow the caller to arbitrarily tinker with the context in which it can be\ncalled. It couldn\u0027t ever be GFP_ATOMIC, for example, because it needs to\ntake the page lock. The only thing any callers care about is __GFP_FS\nanyway, so turn that into a single flag.\n\nAdd a new flag for write_begin, AOP_FLAG_NOFS. Filesystems can now act on\nthis flag in their write_begin function. Change __grab_cache_page to\naccept a nofs argument as well, to honour that flag (while we\u0027re there,\nchange the name to grab_cache_page_write_begin which is more instructive\nand does away with random leading underscores).\n\nThis is really a more flexible way to go in the end anyway -- if a\nfilesystem happens to want any extra allocations aside from the pagecache\nones in ints write_begin function, it may now use GFP_KERNEL (rather than\nGFP_NOFS) for common case allocations (eg. ocfs2_alloc_write_ctxt, for a\nrandom example).\n\n[kosaki.motohiro@jp.fujitsu.com: fix ubifs]\n[kosaki.motohiro@jp.fujitsu.com: fix fuse]\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nReviewed-by: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: \u003cstable@kernel.org\u003e\t\t[2.6.28.x]\nSigned-off-by: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\n[ Cleaned up the calling convention: just pass in the AOP flags\n untouched to the grab_cache_page_write_begin() function.

This patch makes dev_base_head a\nnetwork namespace variable, and then it picks up\na few associated variables.

The rest of the network stack was\nsimply modified to explicitly use \u0026init_net the initial network\nnamespace. This can be fixed when those components of the network\nstack are modified to handle multiple network namespaces.\n\nFor now the ifindex generator is left global.\n\nFundametally ifindex numbers are per namespace, or else\nwe will have corner case problems with migration when\nwe get that far.\n\nAt the same time there are assumptions in the network stack\nthat the ifindex of a network device won\u0027t change. Making\nthe ifindex number global seems a good compromise until\nthe network stack can cope with ifindex changes when\nyou change namespaces, and the like.\n\nSigned-off-by: Eric W.
