* xfs: fix dentry aliasing issues in open_by_handleChristoph Hellwig2009-01-191-168/+137
| | | | | | | | | | | | | | | | | | 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.

This also fixes xfs_compat_ioc_fsgeometry_v1(), which had it backwards before; it copied in an (empty) arg, then copied out the native result, which probably corrupted userspace. It should be translating on the copyout. Also, a bit of formatting cleanup for consistency, and conversion of all error returns to use XFS_ERROR().

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.

* [XFS] simplify vn_revalidateChristoph Hellwig2008-02-071-2/+2
| | | | | | | | | | | | | | | No need to allocate a bhv_vattr_t on stack and call xfs_getattr to update a few fields in the Linux inode from the XFS inode, just do it directly. And yes, this function is in dire need of a better name and prototype, I'll do in a separate patch, though.

* [XFS] 971064 Various fixups for xfs_bulkstat().Lachlan McIlroy2007-12-101-12/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - sanity check for NULL user buffer in xfs_ioc_bulkstat[_compat]() - remove the special case for XFS_IOC_FSBULKSTAT with count == 1. This special case causes bulkstat to fail because the special case uses xfs_bulkstat_single() instead of xfs_bulkstat() and the two functions have different semantics. xfs_bulkstat() will return the next inode after the one supplied while skipping internal inodes (ie quota inodes). xfs_bulkstate_single() will only lookup the inode supplied and return an error if it is an internal inode. - in xfs_bulkstat(), need to initialise 'lastino' to the inode supplied so in cases were we return without examining any inodes the scan wont restart back at zero. - sanity check for valid *ubcountp values. Cannot sanity check for valid ubuffer here because some users of xfs_bulkstat() don't supply a buffer. - checks against 'ubleft' (the space left in the user's buffer) should be against 'statstruct_size' which is the supplied minimum object size. The mixture of checks against statstruct_size and 0 was one of the reasons we were skipping inodes. - if the formatter function returns BULKSTAT_RV_NOTHING and an error and the error is not ENOENT or EINVAL then we need to abort the scan. ENOENT is for inodes that are no longer valid and we just skip them. EINVAL is returned if we try to lookup an internal inode so we skip them too. For a DMF scan if the inode and DMF attribute cannot fit into the space left in the user's buffer it would return ERANGE. We didn't handle this error and skipped the inode. We would continue to skip inodes until one fitted into the user's buffer or we completed the scan. - put back the recalculation of agino (that got removed with the last fix) at the end of the while loop. This is because the code at the start of the loop expects agino to be the last inode examined if it is non-zero. - if we found some inodes but then encountered an error, return success this time and the error next time. If the formatter aborted with ENOMEM we will now return this error but only if we couldn't read any inodes. Previously if we encountered ENOMEM without reading any inodes we returned a zero count and no error which falsely indicated the scan was complete.

* [XFS] cleanup fid types messChristoph Hellwig2007-10-191-12/+12
| | | | | | | | | | | | | | | | | | Currently XFs has three different fid types: struct fid, struct xfs_fid and struct xfs_fid2 with hte latter two beeing identicaly and the first one beeing the same size but an unstructured array with the same size. This patch consolidates all this to alway uuse struct xfs_fid. This patch is required for an upcoming patch series from me that revamps the nfs exporting code and introduces a Linux-wide struct fid.

* [XFS] avoid xfs_getattr in XFS_IOC_FSGETXATTR ioctlChristoph Hellwig2007-10-161-44/+46
| | | | | | | | | | | | | | | No need to call into xfs_getattr and put a big bhv_vattr_t on the stack just to get a little information from the XFS inode. Add a helper called xfs_ioc_fsgetxattr instead that deals with retrieving the information in a clean way.

| | | | | | | | | | | | | | vfs_altfsid was just a pointer to mp->m_fixedfsid so we can trivially replace it with the latter. vfs_fsid also was identical to m_fixedfsid through rather obfuscated ways so we can kill it as well and simply its only user.

| | | | | | | | | | | | | | | All vnode ops now take struct xfs_inode pointers and the behaviour related glue is split out into methods of it's own. This required fixing xfs_create/mkdir/symlink to not mess with the inode pointer but rather use a separate boolean for error handling. Thanks to Dave Chinner for that fix.

* [XFS] Fix XFS_IOC_FSBULKSTAT{,_SINGLE} & XFS_IOC_FSINUMBERS in compat modeMichal Marek2007-07-141-1/+1
| | | | | | | | | | | | | | | | | | | | | * 32bit struct xfs_fsop_bulkreq has different size and layout of members, no matter the alignment. Move the code out of the #else branch (why was it there in the first place?). Define _32 variants of the ioctl constants. * 32bit struct xfs_bstat is different because of time_t and on i386 because of different padding. Make xfs_bulkstat_one() accept a custom "output formatter" in the private_data argument which takes care of the xfs_bulkstat_one_compat() that takes care of the different layout in the compat case. * i386 struct xfs_inogrp has different padding. Add a similar "output formatter" mecanism to xfs_inumbers().

* [XFS] Remove unused header files for MAC and CAP checking functionality.Eric Sandeen2007-02-101-2/+0
| | | | | | | | | | | | | | | | | | xfs_mac.h and xfs_cap.h provide definitions and macros that aren't used anywhere in XFS at all. They are left-overs from "to be implement at some point in the future" functionality that Irix XFS has. If this functionality ever goes into Linux, it will be provided at a different layer, most likely through the security hooks in the kernel so we will never need this functionality in XFS.
