probably I found a bug. Half md4 hash output value is assigned to hash and hash_minor. Linux fsck reports problems (HTREE max value is wrong) on ext partition with a lot directory entries. FreeBSD implementation: http://fxr.watson.org/fxr/source/fs/ext2fs/ext2_hash.c?v=FREEBSD9#L242 Linux implementation: http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/fs/ext3/hash.c Look EXT2_HTREE_HALF_MD4: FreeBSD: major = hash[0]; minor = hash[1]; Linux: minor_hash = buf[2]; hash = buf[1]; >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted: _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "[email protected]"
