* Fix the -ESTALE handling in do_filp_open()Al Viro2010-01-14
| | | | | | | | | Instead of playing sick games with path saving, cleanups, just retry the entire thing once with LOOKUP_REVAL added. Post-.34 we'll convert all -ESTALE handling in there to that style, rather than playing with many retry loops deep in the call chain. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
* Fix ACC_MODE() for realAl Viro2010-01-14
| | | | | | | | | | commit 5300990c0370e804e49d9a59d928c5d53fb73487 had stepped on a rather nasty mess: definitions of ACC_MODE used to be different. Fixed the resulting breakage, converting them to variant that takes O_... value; all callers have that and it actually simplifies life (see tomoyo part of changes).

* fix autofs/afs/etc. magic mountpoint breakageAl Viro2010-01-14
| | | | | | | | | | | | | We end up trying to kfree() nd.last.name on open("/mnt/tmp", O_CREAT) if /mnt/tmp is an autofs direct mount. The reason is that nd.last_type is bogus here; we want LAST_BIND for everything of that kind and we get LAST_NORM left over from finding parent directory. So make sure that it *is* set properly; set to LAST_BIND before doing ->follow_link() - for normal symlinks it will be changed by __vfs_follow_link() and everything else needs it set that way.

* generic_permission: MAY_OPEN is not write accessSerge E. Hallyn2009-12-30
| | | | | | | | | | | | | | | generic_permission was refusing CAP_DAC_READ_SEARCH-enabled processes from opening DAC-protected files read-only, because do_filp_open adds MAY_OPEN to the open mask. Ignore MAY_OPEN. After this patch, CAP_DAC_READ_SEARCH is again sufficient to open(fname, O_RDONLY) on a file to which DAC otherwise refuses us read permission.

* vfs: force reval of target when following LAST_BIND symlinks (try #7)Jeff Layton2009-12-16
| | | | | | | | | | | | | | | | procfs-style symlinks return a last_type of LAST_BIND without an actual path string. This causes __follow_link to skip calling __vfs_follow_link and so the dentry isn't revalidated. This is a problem when the link target sits on NFSv4 as it depends on the VFS to revalidate the dentry before using it on an open call. Ensure that this occurs by forcing a revalidation of the target dentry of LAST_BIND symlinks. Signed-off-by: Jeff Layton <jlayton@redhat.com> Acked-by: "Eric W.

| * vfs: Implement proper O_SYNC semanticsChristoph Hellwig2009-12-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While Linux provided an O_SYNC flag basically since day 1, it took until Linux 2.4.0-test12pre2 to actually get it implemented for filesystems, since that day we had generic_osync_around with only minor changes and the great "For now, when the user asks for O_SYNC, we'll actually give O_DSYNC" comment. This patch intends to actually give us real O_SYNC semantics in addition to the O_DSYNC semantics. After Jan's O_SYNC patches which are required before this patch it's actually surprisingly simple, we just need to figure out when to set the datasync flag to vfs_fsync_range and when not. This patch renames the existing O_SYNC flag to O_DSYNC while keeping it's numerical value to keep binary compatibility, and adds a new real O_SYNC flag. To guarantee backwards compatiblity it is defined as expanding to both the O_DSYNC and the new additional binary flag (__O_SYNC) to make sure we are backwards-compatible when compiled against the new headers. This also means that all places that don't care about the differences can just check O_DSYNC and get the right behaviour for O_SYNC, too - only places that actuall care need to check __O_SYNC in addition. Drivers and network filesystems have been updated in a fail safe way to always do the full sync magic if O_DSYNC is set. The few places setting O_SYNC for lower layers are kept that way for now to stay failsafe. We enforce that O_DSYNC is set when __O_SYNC is set early in the open path to make sure we always get these sane options. Note that parisc really screwed up their headers as they already define a O_DSYNC that has always been a no-op. We try to repair it by using it for the new O_DSYNC and redefinining O_SYNC to send both the traditional O_SYNC numerical value _and_ the O_DSYNC one.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is stage one in flattening out the callchains for the common permission testing. Rather than have most filesystem implement their own inode->i_op->permission function that just calls back down to the VFS layers 'generic_permission()' with the per-filesystem ACL checking function, the filesystem can just expose its 'check_acl' function directly, and let the VFS layer do everything for it.

* Fix i_mutex vs. readdir handling in nfsdDavid Woodhouse2009-04-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 14f7dd63 ("Copy XFS readdir hack into nfsd code") introduced a bug to generic code which had been extant for a long time in the XFS version -- it started to call through into lookup_one_len() and hence into the file systems' ->lookup() methods without i_mutex held on the directory. This patch fixes it by locking the directory's i_mutex again before calling the filldir functions. The original deadlocks which commit 14f7dd63 was designed to avoid are still avoided, because they were due to fs-internal locking, not i_mutex. While we're at it, fix the return type of nfsd_buffered_readdir() which should be a __be32 not an int -- it's an NFS errno, not a Linux errno. And return nfserrno(-ENOMEM) when allocation fails, not just -ENOMEM. Sparse would have caught that, if it wasn't so busy bitching about __cold__. Commit 05f4f678 ("nfsd4: don't do lookup within readdir in recovery code") introduced a similar problem with calling lookup_one_len() without i_mutex, which this patch also addresses. To fix that, it was necessary to fix the called functions so that they expect i_mutex to be held; that part was done by J. Bruce Fields.
