* btrfs-progs: mkfs: fix reading rotational status valueDavid Sterba2016-09-21
| | | | | | | ASAN reports that we're reading beyond the bounds, and is right. The variable is too short to store a nonempty string for atoi. Signed-off-by: David Sterba <dsterba@suse.com>
* btrfs-progs: defrag: set errno correctly in the callbackDavid Sterba2016-09-21
| | | | | | | | | | | In case defrag fails, the errno is not properly reported everywhere but rather the last value of 'e', which could be 0. Then we get confusing error messages like: ERROR: defrag failed on /path/to/file: Success Reported-by: Adam Mizerski <adam@mizerski.pl> Signed-off-by: David Sterba <dsterba@suse.com>

| | | | | | | | | btrfs-progs can't mount space_cache=v2 filesystems read-write, which is why the compat bit wasn't added to the supported mask in the first place. Remove it. Signed-off-by: Omar Sandoval <osandov@fb.com> Signed-off-by: David Sterba <dsterba@suse.com>
* btrfs-progs: reorganize extent_buffer and fix alignment of dataDavid Sterba2016-09-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reported by UBSAN, the checksum code tries to access unaligned data that come from the extent_buffer. struct extent_buffer { struct cache_extent cache_node; /* 0 48 */ u64 start; /* 48 8 */ u64 dev_bytenr; /* 56 8 */ /* --- cacheline 1 boundary (64 bytes) --- */ u32 len; /* 64 4 */ /* XXX 4 bytes hole, try to pack */ struct extent_io_tree * tree; /* 72 8 */ struct list_head lru; /* 80 16 */ struct list_head recow; /* 96 16 */ int refs; /* 112 4 */ u32 flags; /* 116 4 */ int fd; /* 120 4 */ char data[0]; /* 124 0 */ /* size: 128, cachelines: 2, members: 11 */ /* sum members: 120, holes: 1, sum holes: 4 */ /* padding: 4 */ }; Add explicit alignment to data.

* btrfs-progs: avoid looping forever when a bad blockgroup key is foundJeff Mahoney2016-09-21
| | | | | | | | | | | If we discover a bad BLOCK_GROUP_ITEM_KEY with offset = 0, we'll end up looping forever when we read the block groups in. This is due to the search for the next block group starting at the current object + the offset. If offset is 0, we'll just get the same key over and over and never advance. This patch ensures that we'll advance at least one objectid per iteration. Signed-off-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>
