* btrfs-progs: read_tree_block() and read_node_slot() cleanup.Qu Wenruo2015-02-02
| | | | | | | | | | | | Allow read_tree_block() and read_node_slot() to return error pointer. This should help caller to get more specified error number. For existing callers, change (!eb) judgmentt to (!extent_buffer_uptodate(eb)) to keep the compatibility, and for caller missing the check, use PTR_ERR(eb) if possible.

* btrfs-progs: Add repair function for discount file extent hole.Qu Wenruo2015-02-02
| | | | | | | | | | | | Since orphan extents are handled in previous patches, now just punch holes to fill the file extents hole. Also since now btrfsck is aware of whether the inode has orphan file extent, allow repair_inode_no_item() to determine filetype according to orphan file extent.

* btrfs-progs: Add repair and report function for orphan file extent.Qu Wenruo2015-02-02
| | | | | | | | | | | | | | | | | In some fs tree leaf/node corruption case, file extents may be lost, but in extent tree, its record may still exists. This provide the possibility for such orphan file extents to be recovered even we can't recover its compression and other info, we can still insert it as a normal non-compression file extent. This patch provides the repair and report function for such orphan file extent. Even after such repair, user may still need to try to decompress its data if user knows that is a compressed extent.

* btrfs-progs: Record and report every file extent hole.Qu Wenruo2015-02-02
| | | | | | | | | | | | | | | Record every file extent discontinuous hole in inode_record using a rb_tree member. Before the patch, btrfsck will only record the first file extent hole by using first_extent_gap, that's good for detecting error, but not suitable for fixing it. This patch provides the ability to record every file extent hole and report it. Signed-off-by: Qu Wenruo <quwenruo@cn.fujitsu.com> Signed-off-by: David Sterba <dsterba@suse.cz>
* btrfs-progs: Add btrfs_get_extent() and btrfs_punch_hole().Qu Wenruo2015-02-02
| | | | | | | | | | | | | | | | | | | Add btrfs_get_extent() and btrfs_punch_hole() for btrfs-progs. Btrfs_get_extent() will act much like kernel one, return the first extent that covers the given range. The difference will be that progs btrfs_get_extent() can't handle no-holes feature, which means caller should handle it carefully. Btrfs_punch_hole() will punch a hole in given range of given inode, however it differs from kernel one since it won't zero any page or drop any extents if there is any extent in the hole range. These functions are mainly used for later I_ERR_FILE_EXTENT_DISCOUNT repair function. Signed-off-by: Qu Wenruo <quwenruo@cn.fujitsu.com> Signed-off-by: David Sterba <dsterba@suse.cz>
* btrfs-progs: Record orphan data extent ref to corresponding root.Qu Wenruo2015-02-02
| | | | | | | | | | | | | | | | | | | | | | Before this patch, when a extent's data ref points to a invalid key in fs tree, this happens if a leaf/node of fs tree is corrupted, btrfsck can't do any repair and just exit. In fact, such problem can be handled in fs tree repair routines, rebuild the inode item(if missing) and add back the extent data (with some assumption). So this patch records such data extent refs for later fs tree recovery routine. TODO: Restore orphan data extent refs into btrfs_root is not the best method. It's best to directly restore it into inode_record, however current extent tree and fs tree can't cooperate together, so use btrfs_root as a temporary storage until inode_cache is built.

* btrfs-progs: Make option parsing more robust to code modificationsHugo Mills2015-01-27
| | | | | | | | | | | | | | The current approach to option parsing, where long-only options are selected on the basis of their position in the long_options array is fragile and painful to modify if options are to be inserted into the list, rather than appended. Instead, use the last field of struct option to return a value which cannot be a char (and hence a short option), and simply switch on those within the case statement.

* btrfs-progs: drop feature defines from C files, in favour of CFLAGS definesDimitri John Ledkov2015-01-27
| | | | | | | | | | | | | | | | | | | | | | glibc 2.10+ (5+ years old) enables all the desired features: _XOPEN_SOURCE 700, __XOPEN2K8, POSIX_C_SOURCE, DEFAULT_SOURCE; with a single _GNU_SOURCE define in the makefile alone. For portability to other libc implementations (e.g. dietlibc) _XOPEN_SOURCE=700 is also defined. This also resolves Debian bug report filed by Michael Tautschnig - "Inconsistent use of _XOPEN_SOURCE results in conflicting declarations". Whilst I was not able to reproduce the results, the reported fact is that _XOPEN_SOURCE set to 500 in one set of files (e.g. cmds-filesystem.c) generates/defines different struct stat from other files (cmds-replace.c). This patch thus cleans up all feature defines, and sets them at a consistent level.
