Hi All, This updated patchset is on top of ad81f054 of xfs git (3.11-rc1). The patches do not convert the id's returned from bulkstat, since bulkstat cannot be called from inside a userns right now anyway since the caller must be CAP_SYS_ADMIN in init_user_ns. Changes since v6 patchset (addressing Dave's comments) - 0006 just do a capable(CAP_SYS_ADMIN) check for XFS_IOC_FREE_EOFBLOCKS Changes since v5 patchset (addressing Brian's comments, only 0005 and 0006 are changed): - 0005 put all eofblocks validation in xfs_fs_eofblocks_from_user() - 0006 don't export internal flag, add K to internal flag name, start internal flags bits at msb (with the intention that other internal flags would be in descending order) and ensure that it doesn't accidentally collide with external flags Changes since v4 patchset (addressing Dave's comments): - add parenthesis in if with binary and logical and (EOFBLOCKS flags) - rename xfs_fs_eofblocks_to_internal -> xfs_fs_eofblocks_from_user and move conversion validation into it - fix negative error returns from XFS_IOC_FREE_EOFBLOCKS - add check for read-only filesystem to XFS_IOC_FREE_EOFBLOCKS Changes since v3 patchset: - export inode_capable() for building xfs as a module - implement Brian's proposal for an internal flag to indicate to xfs_inode_free_eofblocks() that it should do a permission check. ioctl callers will always set this flag, which is simpler than making them specify XFS_EOF_FLAGS_UID or XFS_EOF_FLAGS_GID, internal callers can leave it unset so no permission checking is done - take Brian's suggestion on moving the policy from the conversion function into the ioctl code, and moving stuff to xfs_icache.h _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
