recover_prepare() in chunk-recover.c alloc memory which only contains sizeof(struct btrfs_super_block). This will cause glibc malloc error after superblock csum is calculated. Use BTRFS_SUPER_INFO_SIZE to fix the bug. Signed-off-by: Qu Wenruo <quwenruo@cn.fujitsu.com> --- chunk-recover.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
