The value of fattr-\u003etime_start is propagated to\nread_cache_jiffies by nfs_update_inode(). Subsequent calls to\nnfs_attribute_timeout() will then use a good time stamp when\ncomputing the attribute cache timeout, and squelch unneeded GETATTR\ncalls.\n\nSince the direct I/O paths erroneously leave the inode\u0027s\nfattr-\u003etime_start field set to zero, read_cache_jiffies for that inode\nis set to zero after any direct read or write operation. This\ntriggers an otw GETATTR or ACCESS call to update the file\u0027s attribute\nand access caches properly, even when the NFS READ or WRITE replies\nhave usable post-op attributes.\n\nMake sure the direct read and write setup code performs the same fattr\ninitialization as the cached I/O paths to prevent unnecessary GETATTR\ncalls.\n\nThis was likely introduced by commit 0e574af1 in 2.6.15, which appears\nto add new nfs_fattr_init() call sites in the cached read and write\npaths, but not in the equivalent places in fs/nfs/direct.c. A\nsubsequent commit in the same series, 33801147, introduces the\nfattr-\u003etime_start field.\n\nInterestingly, the direct write reschedule path already has a call to\nnfs_fattr_init() in the right place.\n\nReported-by: Quentin Barnes \u003cqbarnes@yahoo-inc.com\u003e\nSigned-off-by: Chuck Lever \u003cchuck.lever@oracle.com\u003e\nCc: stable@kernel.org\nSigned-off-by: Trond Myklebust

flag basically since day 1, it took until\nLinux 2.4.0-test12pre2 to actually get it implemented for filesystems,\nsince that day we had generic_osync_around with only minor changes and the\ngreat \"For now, when the user asks for O_SYNC, we\u0027ll actually give\nO_DSYNC\" comment. 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. We try to repair it by using it for\nthe new O_DSYNC and redefinining O_SYNC to send both the traditional\nO_SYNC numerical value _and_ the O_DSYNC one.\n\nCc: Richard Henderson \u003crth@twiddle.net\u003e\nCc: Ivan Kokshaysky \u003cink@jurassic.park.msu.ru\u003e\nCc: Grant Grundler \u003cgrundler@parisc-linux.org\u003e\nCc: \"David S.

Text-based mounts use the smaller of the server\u0027s maximum\nand the client\u0027s maximum, but binary mounts use the smaller of the\nserver\u0027s _preferred_ size and the client\u0027s maximum.\n\nThis difference is actually pretty subtle. Most servers advertise\nthe same value as their maximum and their preferred transfer size, so\nthe end result is the same in most cases.\n\nThe reason for this difference is that for text-based mounts, if\nr/wsize are not specified, they are set to the largest value supported\nby the client. For legacy mounts, the values are set to zero if these\noptions are not specified.\n\nnfs_server_set_fsinfo() can negotiate the transfer size defaults\ncorrectly in any case. There\u0027s no need to specify any particular\nvalue as default in the text-based option parsing logic.\n\nNote that nfs4 doesn\u0027t use nfs_server_set_fsinfo(), but the mount.nfs4\ncommand does set rsize and wsize to 0 if the user didn\u0027t specify these\noptions. So, make the same change for text-based NFSv4 mounts.\n\nThanks to James Pearson \u003cjames-p@moving-picture.com\u003e for reporting and\ndiagnosing the problem.\n\nSigned-off-by: Chuck Lever \u003cchuck.lever@oracle.com\u003e\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "d250e190fb9b06f4c595eade88b3d0b705fb330a", "tree": "963505275d87d596b674b061403cf6fa18b01f25", "parents": [ "dd1fd90fe65e2e642f0e58e2ff4849f317a6c43d" ], "author": { "name": "Chuck Lever", "email": "chuck.lever@oracle.com", "time": "Thu Dec 03 15:58:56 2009 -0500" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Thu Dec 03 15:58:56 2009 -0500" }, "message": "NFS: Display compressed (shorthand) IPv6 in /proc/mounts\n\nRecent changes to snprintf() introduced the %pI6c formatter, which can\ndisplay an IPv6 address with standard shorthanding.

Until\nrecently, this has never really been an issue for Linux since it didn\u0027t\nsupport NFS over IPv6. The netid and the protocol name were generally\nalways the same (modulo any strange configuration in /etc/netconfig).\n\nThe solaris manpage documents their proto\u003d option as:\n\n proto\u003d _netid_ | rdma\n\nThis patch is intended to bring Linux closer to how the Solaris proto\u003d\noption works, by declaring a static netid mapping in the kernel and\nconverting the proto\u003d and mountproto\u003d options to follow it and display\nthe proper values in /proc/mounts.\n\nMuch of this functionality will need to be provided by a userspace\nmount.nfs patch. Chuck Lever has a patch to change mount.nfs in\nthe same way. In principle, we could do *all* of this in userspace but\nthat would mean that the options in /proc/mounts may not match the\noptions used by userspace.\n\nThe alternative to the static mapping here is to add a mechanism to\nupcall to userspace for netid\u0027s. I\u0027m not opposed to that option, but\nit\u0027ll probably mean more overhead (and quite a bit more code). Rather\nthan shoot for that at first, I figured it was probably better to\nstart simply.\n\nComments welcome.\n\nSigned-off-by: Jeff Layton \u003cjlayton@redhat.com\u003e\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "d4e935bd67ca05db4119b67801d9ece6ae139f05", "tree": "56d6c6e3e6cf9ecd0538cacb5cafb4477d015b4b", "parents": [ "96f287b0cf512ee537826943c15b0b8647472f70" ], "author": { "name": "J.
