* btrfs-progs: Use helper function to access ↵Chandan Rajendra2016-12-14
| | | | | | | | | | | | | btrfs_super_block->sys_chunk_array_size btrfs_super_block->sys_chunk_array_size is stored as le32 data on disk. However insert_temp_chunk_item() writes sys_chunk_array_size in host cpu order. This commit fixes this by using super block access helper functions to read and write btrfs_super_block->sys_chunk_array_size field.

* btrfs-progs: Remove duplicate printfs in warning_trace()/assert_trace()Goldwyn Rodrigues2016-12-14
| | | | | | | | | Code reduction. Call warning_trace from assert_trace in order to reduce the printf's used. Also, trace variable in warning_trace() is not required because it is already handled by BTRFS_DISABLE_BACKTRACE.

* btrfs-progs: Correct value printed by assertions/BUG_ON/WARN_ONGoldwyn Rodrigues2016-12-14
| | | | | | | | | | | | | | | The values passed to BUG_ON/WARN_ON are negated(!) and printed, which results in printing the value zero for each bug/warning. For example: volumes.c:988: btrfs_alloc_chunk: Assertion `ret` failed, value 0 This is not useful. Instead changed to print the value of the parameter passed to BUG_ON()/WARN_ON(). The value needed to be changed to long to accomodate pointers being passed. Also, consolidated assert() and BUG() into ifndef.

| | | | | | | | | | | | | | | allocation failure We didn't check 'path' allocated in check_root_ref(), which can cause NULL pointer dereference if the memory allocation failed.

* btrfs-progs: check: Enhance leaf traversal function to handle missing inode itemQu Wenruo2016-12-14
| | | | | | | | | | | | | | | | | | | | | The leaf traversal function in lowmem mode will skip to the first inode item of leaf and begin to check the inode. That's designed to avoid checking overlapping part of a leaf. But that will cause problem in fsck/010 test case, as in that case inode item of the first inode(256) is missing. So above traversal will check from inode 257 and found nothing wrong. The fix is done in 2 part: 1) Manually check the first inode To avoid case like fsck/010 2) Check inode if ino changes from the first ino of a leaf To avoid missing inode_item problem.

* btrfs-progs: check: skip shared node or leaf check for low_memory modeWang Xiaoguang2016-12-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The basic idea is simple. Assume a middle tree node A is shared and its referencing fs/file tree root ids are 5, 258 and 260, then we only check node A in the tree who has the smallest root id. That means in this case, when checking root tree(5), we check inode A, for root tree 258 and 260, we can just skip it. Notice even with this patch, we still may visit a shared node or leaf multiple times. This happens when a inode metadata occupies multiple leaves. leaf_A leaf_B When checking inode item in leaf_A, assume inode[512] have file extents in leaf_B, and leaf_B is shared. In the case, for inode[512], we must visit leaf_B to have inode item checked. After finishing inode[512] check, here we walk down tree root to leaf_B to check whether node or leaf is shared, if some node or leaf is shared, we can just skip it and below nodes or leaf's check. I also fill a disk partition with linux source codes and create 3 snapshots in it. Before this patch, it averagely took 46s to finish one btrfsck execution, with this patch, it averagely took 15s.

* btrfs-progs: check: fix the return value bug of cmd_check()Lu Fengqi2016-12-14
| | | | | | | | | | | | The function cmd_check() is called by the main function of btrfs.c, its return value will be returned by exit(). Resulting in the loss of significant bits in some cases, for example this value is greater than 0377. If use a bool value "err" to store all of the return value, this will solve the problem.
