Subject: xfsprogs: xfs_db endianness problem

Date: Sat, 25 May 2002 04:11:06 -0400

Package: xfsprogs
Version: 2.0.4-1
Severity: important

To reproduce on i386, select an inode, set type to agi, and attempt to
write a number to unlinked.

786824 shows up as 2365656064

It is unclear whether the bytes are swapped incorrectly for display
purposes or on disk.

[I assume you realise this is a bogus thing to do (effectively "casting"
an inode to an AGI and then writing at some arbitrary offset in the inode),
and is guaranteed to cause filesystem corruption].

There are several known endian problems in xfs_db's write mode.  I'll
open a bug upstream so they don't forget about them.

> Severity: important

Hmm.. xfs_db's write feature requires expert mode, and is not very
widely used.  If this is indeed an endian problem then the workaround
is simple (convert numbers manually before writing).  I'll probably
downgrade the priority of this bug to "normal".

thanks.

Well, I thought it might help with the /etc/motd problem.  It didn't.
Instead I ended up deleting another file in /etc.

There was another command which I executed that displayed something
byteswapped, but I've forgotten what that is.
