I am experiencing the same issue in my custom Buildroot installation on an older Linksys DNS-320 with a Marvell ARMv5 Xscale processor, which is the same model used in the...

It was easy to reproduce the bug caused by reading a 16-bit word from an uneven address, resulting in byte flipping on the ARMv5 and causing an error. I have...

A 360gb backup was perfect using patched branch. But how about this: In libbtrfs/send.h the following struct is defined struct btrfs_cmd_header { /* len excluding the header */ __le32 len;...

There is more. line 144 'sctx->cmd_hdr->crc = 0;' should be 'put_unaligned_le32(0, sctx->cmd_hdr->crc)' in common/send-stream.c line 163 'crc = le32_to_cpu(cmd_hdr->crc);', line 165 'cmd_hdr->crc = 0;'

> AFAIK the strict alignment architectures can work in several modes, where an unaligned read is a hard error, or an exception (fixup mode?) An unaligned access mode was introduced...

Integers in btrfs_dir_item are byte aligned since 'struct btrfs_disk_key' it contains is 17 bytes long. libbtrfsutil/subvolume.c: line 610: name_len = le16_to_cpu(dir->name_len); - should it be ... get_unaligned_le16(dir->name_len); cmds/rescue-chunk-recover.c: ??? u8...

The performance of Btrfs can be significantly improved on hardware that requires software fallback to handle word alignment corrections. Specifically, when get_unaligned_le64 is called since it forces software handling, which...
