      [PATCH] sanitize __user_walk_fd() et.al. · 2d8f3038
      由 Al Viro 提交于 
      * 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.

      [XFS] 971064 Various fixups for xfs_bulkstat(). · cd57e594
      由 Lachlan McIlroy 提交于 
      - 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  is for inodes that are no longer valid and we just skip them.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 mess · c6143911
      由 Christoph Hellwig 提交于 
      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] Fix XFS_IOC_FSBULKSTAT{,_SINGLE} & XFS_IOC_FSINUMBERS in compat mode · faa63e95
      由 Michal Marek 提交于 
      * 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().
