Currently on-disk structure is able to keep only 16bit project quota id, so disallow 32bit ones. This fixes a problem where parts of kernel structures holding project quota id are 32bit while parts (on-disk) are 16bit variables which causes project quota member files to be inaccessible for some operations (like mv/rm).

Replace the xfs_itrace_entry catchall with specific trace points. For most simple callers we now use the simple inode class, which used to be the iget class, but add more details tracing for namespace events, which now includes the name of the directory entries manipulated. Remove the xfs_inactive trace point, which is a duplicate of the clear_inode one, and the xfs_change_file_space trace point, which is immediately followed by the more specific alloc/free space trace points.

Currently we need to either call IHOLD or xfs_trans_ihold on an inode when joining it to a transaction via xfs_trans_ijoin. This patches instead makes xfs_trans_ijoin usable on it's own by doing an implicity xfs_trans_ihold, which also allows us to drop the third argument. For the case where we want to hold a reference on the inode a xfs_trans_ijoin_ref wrapper is added which does the IHOLD and marks the inode for needing an xfs_iput. In addition to the cleaner interface to the caller this also simplifies the implementation. Signed-off-by: NChristoph Hellwig <hch@lst.de> Reviewed-by: NDave Chinner <dchinner@redhat.com>

Dmapi support was never merged upstream, but we still have a lot of hooks bloating XFS for it, all over the fast pathes of the filesystem. This patch drops over 700 lines of dmapi overhead. If we'll ever get HSM support in mainline at least the namespace events can be done much saner in the VFS instead of the individual filesystem, so it's not like this is much help for future work.

The non-coherent bulkstat versionsthat look directly at the inode buffers causes various problems with performance optimizations that make increased use of just logging inodes.

The am_hreq.opcount field in the xfs_attrmulti_by_handle() interface is not bounded correctly. The opcount is used to determine the size of the buffer required. The size is bounded, but can overflow and so the size checks may not be sufficient to catch invalid opcounts. Fix it by catching opcount values that would cause overflows before calculating the size.

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

Convert the old xfs tracing support that could only be used with the out of tree kdb and xfsidbg patches to use the generic event tracer. To use it make sure CONFIG_EVENT_TRACING is enabled and then enable all xfs trace channels by: echo 1 > /sys/kernel/debug/tracing/events/xfs/enable or alternatively enable single events by just doing the same in one event subdirectory, e.g. echo 1 > /sys/kernel/debug/tracing/events/xfs/xfs_ihold/enable or set more complex filters, etc. In Documentation/trace/events.txt all this is desctribed in more detail. To reads the events do a cat /sys/kernel/debug/tracing/trace Compared to the last posting this patch converts the tracing mostly to the one tracepoint per callsite model that other users of the new tracing facility also employ. This allows a very fine-grained control of the tracing, a cleaner output of the traces and also enables the perf tool to use each tracepoint as a virtual performance counter, allowing us to e.g. count how often certain workloads git various spots in XFS. Take a look at http://lwn.net/Articles/346470/ for some examples. Also the btree tracing isn't included at all yet, as it will require additional core tracing features not in mainline yet, I plan to deliver it later.

Kill the quota ops function vector and replace it with direct calls or stubs in the CONFIG_XFS_QUOTA=n case. Make sure we check XFS_IS_QUOTA_RUNNING in the right spots. We can remove the number of those checks because the XFS_TRANS_DQ_DIRTY flag can't be set otherwise. This brings us back closer to the way this code worked in IRIX and earlier Linux versions, but we keep a lot of the more useful factoring of common code. Eventually we should also kill xfs_qm_bhv.c, but that's left for a later patch.

Open by handle just grabs an inode by handle and then creates itself a dentry for it. While this works for regular files it is horribly broken for directories, where the VFS locking relies on the fact that there is only just one single dentry for a given inode, and that these are always connected to the root of the filesystem so that it's locking algorithms work (see Documentations/filesystems/Locking) Remove all the existing open by handle code and replace it with a small wrapper around the exportfs code which deals with all these issues. At the same time we also make the checks for a valid handle strict enough to reject all not perfectly well formed handles - given that we never hand out others that's okay and simplifies the code.

Preliminary work to hook up fiemap, this allows us to pass in an arbitrary formatter to copy extent data back to userspace. The formatter takes info for 1 extent, a pointer to the user "thing*" and a pointer to a "filled" variable to indicate whether a userspace buffer did get filled in (for fiemap, hole "extents" are skipped). I'm just using the getbmapx struct as a "common denominator" because as far as I can see, it holds all info that any formatters will care about.

These days most of the attributes in struct inode are properly kept in sync by XFS. This patch removes the need for vn_revalidate completely by: - keeping inode.i_flags uptodate after any flags are updated in xfs_ioctl_setattr - keeping i_mode, i_uid and i_gid uptodate in xfs_setattr SGI-PV: 984566 SGI-Modid: xfs-linux-melb:xfs-kern:31679a Signed-off-by: NChristoph Hellwig <hch@infradead.org> Signed-off-by: NTim Shimmin <tes@sgi.com> Signed-off-by: NLachlan McIlroy <lachlan@sgi.com>

it can be switched to take struct iattr directly and thus simplify the implementation greatly. Also rename the ATTR_ flags to XFS_ATTR_ to not conflict with the ATTR_ flags used by the VFS.

->setattr but also addition XFS-specific attributes: project id, inode flags and extent size hint. Having these in a single function makes it more complicated and forces to have us a bhv_vattr intermediate structure eating up stackspace. This patch adds a new xfs_ioctl_setattr helper for the XFS ioctls that set these attributes and remove the code to set them through xfs_setattr.

xfs_attrmulti_by_handle currently request the size based on sizeof(attr_multiop_t) but should be using sizeof(xfs_attr_multiop_t) because that is what it is dealing with. Despite beeing wrong this actually harmless in practice because both structures are the same size on all platforms. But this sizeof was the only user of struct attr_multiop so we can just kill it. Also move the ATTR_OP_* defines xfs_attr.h into the struct xfs_attr_multiop defintion in xfs_fs.h because they are only used with that structure, and are part of the user ABI for the XFS_IOC_ATTRMULTI_BY_HANDLE ioctl.

xfs_attrlist_by_handle should only take the ATTR_ flags for the root namespaces. The ATTR_KERN* flags may change at anytime and expect special preconditions that can't be guaranteed for userspace-originating requests. For example passing down ATTR_KERNNOVAL through xfs_attrlist_by_handle will hit an assert in debug builds currently.

* do not pass nameidata; struct path is all the callers want. * switch to new helpers: user_path_at(dfd, pathname, flags, &path) user_path(pathname, &path) user_lpath(pathname, &path) user_path_dir(pathname, &path) (fail if not a directory) The last 3 are trivial macro wrappers for the first one. * remove nameidata in callers.

Unless XFS_IGET_CREATE is passed xfs_iget will return ENOENT if it encounters an inode with di_mode == 0. Remove the duplicated checks in the callers.
