* btrfs-progs: check link_subvol name baseZach Brown2013-10-16
| | | | | | | | | | | | | In principle, link_subvol() can be given an abitrary string as the name of the saved subvolume. It copies it into a fixed-size stack buffer and then uses it as dirent names without testing its length. This limits its length to BTRFS_NAME_LEN. This was found by static analsys.

* Btrfs-progs: enhance btrfs qgroup to print the result as a tableWang Shilong2013-10-16
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch enhance to print the result as a table. You can use it like: btrfs qgroup show <path> However, to table the result better, we make '-p' and '-c' not present at the same time. For example: btrfs qgroup show -pr <path> The result will output as the follow format: qgroupid rfer excl max_excl parent -------- ---- ---- -------- ------ 0/265 1289752576 1289752576 0 --- 1/0 0 0 10999511627776 2/0,3/0 2/0 0 0 0 --- 3/0 0 0 0 --- Signed-off-by: Wang Shilong <wangsl-fnst@cn.fujitsu.com> Signed-off-by: Miao Xie <miaox@cn.fujitsu.com> Signed-off-by: David Sterba <dsterba@suse.cz> Signed-off-by: Chris Mason <chris.mason@fusionio.com>
* Btrfs-progs: enhance btrfs qgroup show to sort qgroupsWang Shilong2013-10-16
| | | | | | | | | | | | | | | | | | | | | | | You might want to list qgroups in order of some items, such as 'qgroupid', 'rfer' and so on, you can use '--sort'. Now you can sort the qgroups by 'qgroupid', 'rfer','excl','max_rfer' and 'max_excl'. For example: If you want to list qgroups in order of 'qgroupid'. You can use the option like that: btrfs qgroup show --sort=+/-qgroupid <path> Here, '+' means the result is sorted by ascending order. '-' is by descending order. If you don't specify either '+' nor '-', the result is sorted by default - ascending order. If you want to combine sort items, you do it like that: btrfs qgroup show --sort=-qgroupid,+rfer,max_rfer,excl <path> Signed-off-by: Wang Shilong <wangsl-fnst@cn.fujitsu.com> Signed-off-by: Miao Xie <miaox@cn.fujitsu.com> Signed-off-by: David Sterba <dsterba@suse.cz> Signed-off-by: Chris Mason <chris.mason@fusionio.com>

* Btrfs-progs: restructure show_qgroupsWang Shilong2013-10-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current show_qgroups() just shows a little information, and it is hard to add some functions which the users need in the future, so i restructure it, make it easy to add new functions. In order to improve the scalability of show_qgroups(), i add some important structures: struct qgroup_lookup { struct rb_root root; } /* *store qgroup's information */ struct btrfs_qgroup { struct rb_node rb_node; u64 qgroupid; u64 generation; u64 rfer; u64 rfer_cmpr; u64 excl_cmpr; u64 flags; u64 max_rfer; u64 max_excl; u64 rsv_rfer; u64 rsv_excl; struct list_head qgroups; struct list_head members; } /* *glue structure to represent the relations *between qgroups */ struct btrfs_qgroup_list { struct list_head next_qgroups; struct list_head next_member; struct btrfs_qgroup *qgroup; struct btrfs_qgroup *member; } The above 3 structures are used to manage all the information of qgroups. struct { char *name; char *column_name; int need_print; } btrfs_qgroup_columns[] We define a arrary to manage all the columns that can be outputed, and use a member variant(->need_print) to control the output of the relative column. Some columns are outputed by default. But we can change it according to the requirement of the users. For example: if outputing max referenced size of qgroup is needed,the function 'btrfs_qgroup_setup_column()' will be called, and the parameter 'BTRFS_QGROUP_MAX_RFER' (extend in the future) will be passsed to the function. After the function is done, when showing qgroups, max referenced size of qgroup will be output.

* Btrfs-progs: print out human readable errors for inodes and backrefsJosef Bacik2013-10-16
| | | | | | | | | | | | | We usually print out a hex value of any errors on inodes or their backrefs, which is a huge pain for me because I have to put it into a calculator and count the bits to figure out which errors these map to, and usually I get it wrong the first time.

* Btrfs-progs: keep track of transid failures and fix them if possibleJosef Bacik2013-10-16
| | | | | | | | | | | | | A user was reporting an issue with bad transid errors on his blocks. The thing is that btrfs-progs will ignore transid failures for things like restore and fsck so we can do a best effort to fix a users file system. So fsck can put together a coherent view of the file system with stale blocks. So if everything else is ok in the mind of fsck then we can recow these blocks to fix the generation and the user can get their file system back.

* Btrfs-progs: add super-recover to recover bad supersWang Shilong2013-10-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Until now if one of device's first superblock is corrupt,btrfs will fail to mount. Luckily, btrfs have at least two superblocks for every disk. In theory, if silent corrupting happens when we are writting superblocks into disk, we must hold at least one good superblock. One side effect is that user must gurantee that the disk must be a btrfs disk. Otherwise, this tool may destroy other fs.(This is also reason why btrfs only use first superblock in every disk to mount) This little program will try to correct bad superblocks from good superblocks with max generation. There will be five kinds of return values: 0: all supers are valid, no need to recover 1: usage or syntax error 2: recover all bad superblocks successfully 3: fail to recover bad superblocks 4: abort to recover bad superblocks Signed-off-by: Wang Shilong <wangsl.fnst@cn.fujitsu.com> Signed-off-by: David Sterba <dsterba@suse.cz> Signed-off-by: Chris Mason <chris.mason@fusionio.com>

* btrfs-progs: separate command and implementation of chunk-recover codeDavid Sterba2013-10-16
| | | | | | | | | | | | | The command has been moved and we should rename the files accordingly, so the entry point is now in cmds-rescue.c and the core functionality in it's own file. Return codes of btrfs_recover_chunk_tree have been simplified not to require a define and another file for defintion.
