* [XFS] use minleft when allocating in xfs_bmbt_split()Lachlan McIlroy2008-07-282-1/+24
| | | | | | | | | | | | | | | | The bmap btree split code relies on a previous data extent allocation (from xfs_bmap_btalloc()) to find an AG that has sufficient space to perform a full btree split, when inserting the extent. When converting unwritten extents we don't allocate a data extent so a btree split will be the first allocation. In this case we need to set minleft so the allocator will pick an AG that has space to complete the split(s).

* [XFS] attrmulti cleanupChristoph Hellwig2008-07-283-17/+4
| | | | | | | | | | | | | | | | | | | | | | 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] Check for invalid flags in xfs_attrlist_by_handle.Christoph Hellwig2008-07-281-0/+6
| | | | | | | | | | | | | | | | 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.

* [XFS] Always reset btree cursor after an insertLachlan McIlroy2008-07-282-37/+14
| | | | | | | | | | | | | | | | After a btree insert operation a cursor can be invalid due to block splits and a maybe a new root block. We reset the cursor in xfs_bmbt_insert() in the cases where we think we need to but it isn't enough as we still see assertions. Just do what we do elsewhere and reset the cursor unconditionally. Also remove the fix to revalidate the original cursor in xfs_bmbt_insert().

* [XFS] Fix returning case-preserved name with CI node form directoriesBarry Naujok2008-07-281-26/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | xfs_dir2_node_lookup() calls xfs_da_node_lookup_int() which iterates through leaf blocks containing the matching hash value for the name being looked up. Inside xfs_da_node_lookup_int(), it calls the xfs_dir2_leafn_lookup_for_entry() for each leaf block. xfs_dir2_leafn_lookup_for_entry() iterates through each matching hash/offset pair doing a name comparison to find the matching dirent. For CI mode, the state->extrablk retains the details of the block that has the CI match so xfs_dir2_node_lookup() can return the case-preserved name. The original implementation didn't retain the xfs_da_buf_t properly, so the lookup was returning a bogus name to be stored in the dentry. In the case of unlink, the bad name was passed and in debug mode, ASSERTed when it can't find the entry.

* [XFS] fix extent corruption in xfs_iext_irec_compact_full()Lachlan McIlroy2008-07-281-23/+47
| | | | | | | | | | | | | | | | | This function is used to compact the indirect extent list by moving extents from one page to the previous to fill them up. After we move some extents to an earlier page we need to shuffle the remaining extents to the start of the page. The actual bug here is the second argument to memmove() needs to index past the extents, that were copied to the previous page, and move the remaining extents. For pages that are already full (ie ext_avail == 0) the compaction code has no net effect so don't do it.

* [XFS] Pack some shortform dir2 structures for the ARM old ABIEric Sandeen2008-07-282-3/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | architecture. This should fix the longstanding issues with xfs and old ABI arm boxes, which lead to various asserts and xfs shutdowns, and for which an (incorrect) patch has been floating around for years. I've verified this patch by comparing the on-disk structure layouts using pahole from the dwarves package, as well as running through a bit of xfsqa under qemu-arm, modified so that the check/repair phase after each test actually executes check/repair from the x86 host, on the filesystem populated by the arm emulator. Thus far it all looks good. There are 2 other structures with extra padding at the end, but they don't seem to cause trouble. I suppose they could be packed as well: xfs_dir2_data_unused_t and xfs_dir2_sf_t. Note that userspace needs a similar treatment, and any filesystems which were running with the previous rogue "fix" will now see corruption (either in the kernel, or during xfs_repair) with this fix properly in place; it may be worth teaching xfs_repair to identify and fix that specific issue.

* [XFS] XFS: ASCII case-insensitive supportBarry Naujok2008-07-286-4/+68
| | | | | | | | | | | | | | | | | | | | | Implement ASCII case-insensitive support. It's primary purpose is for supporting existing filesystems that already use this case-insensitive mode migrated from IRIX. But, if you only need ASCII-only case-insensitive support (ie. English only) and will never use another language, then this mode is perfectly adequate. ASCII-CI is implemented by generating hashes based on lower-case letters and doing lower-case compares. It implements a new xfs_nameops vector for doing the hashes and comparisons for all filename operations. To create a filesystem with this CI mode, use: # mkfs.xfs -n version=ci <device> SGI-PV: 981516 SGI-Modid: xfs-linux-melb:xfs-kern:31209a Signed-off-by: Barry Naujok <bnaujok@sgi.com> Signed-off-by: Christoph Hellwig <hch@infradead.org>
* [XFS] Return case-insensitive match for dentry cacheBarry Naujok2008-07-2812-29/+146
| | | | | | | | | | | | | | | | | | | | | | | | | | This implements the code to store the actual filename found during a lookup in the dentry cache and to avoid multiple entries in the dcache pointing to the same inode. To avoid polluting the dcache, we implement a new directory inode operations for lookup. xfs_vn_ci_lookup() stores the correct case name in the dcache. The "actual name" is only allocated and returned for a case- insensitive match and not an actual match. Another unusual interaction with the dcache is not storing negative dentries like other filesystems doing a d_add(dentry, NULL) when an ENOENT is returned. During the VFS lookup, if a dentry returned has no inode, dput is called and ENOENT is returned. By not doing a d_add, this actually removes it completely from the dcache to be reused. create/rename have to be modified to support unhashed dentries being passed in.

* [XFS] Name operation vector for hash and compareBarry Naujok2008-07-289-67/+174
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds two pieces of functionality for the basis of case-insensitive support in XFS: 1. A comparison result enumerated type: xfs_dacmp. It represents an exact match, case-insensitive match or no match at all. This patch only implements different and exact results. 2. xfs_nameops vector for specifying how to perform the hash generation of filenames and comparision methods. In this patch the hash vector points to the existing xfs_da_hashname function and the comparison method does a length compare, and if the same, does a memcmp and return the xfs_dacmp result. All filename functions that use the hash (create, lookup remove, rename, etc) now use the xfs_nameops.hashname function and all directory lookup functions also use the xfs_nameops.compname function. The lookup functions also handle case-insensitive results even though the default comparison function cannot return that. And important aspect of the lookup functions is that an exact match always has precedence over a case-insensitive. So while a case-insensitive match is found, we have to keep looking just in case there is an exact match. In the meantime, the info for the first case-insensitive match is retained if no exact match is found.

| | | | | | | | | | | | | | | | | xfs_unmount is small and already pretty Linux specific, so merge it into the callers.

* [XFS] kill xfs_igrow_start and xfs_igrow_finishChristoph Hellwig2008-07-283-67/+12
| | | | | | | | | | | | | | | | | | xfs_igrow_start just expands to xfs_zero_eof with two asserts that are useless in the context of the only caller and some rather confusing comments. xfs_igrow_finish is just a few lines of code decorated again with useless asserts and confusing comments. Just kill those two and merge them into xfs_setattr.

* [XFS] Convert l_flushsema to a sv_tMatthew Wilcox2008-07-282-20/+15
| | | | | | | | | | | | | | | | | | | | | The l_flushsema doesn't exactly have completion semantics, nor mutex semantics. It's used as a list of tasks which are waiting to be notified that a flush has completed. It was also being used in a way that was potentially racy, depending on the semaphore implementation. By using a sv_t instead of a semaphore we avoid the need for a separate counter, since we know we just need to wake everything on the queue. Original waitqueue implementation from Matthew Wilcox. Cleanup and conversion to sv_t by Christoph Hellwig.

Previously, mounting with noattr2 failed to achieve anything because although it cleared the attr2 mount flag, it would set it again as soon as it processed the superblock fields.
