Confusion over mkfs.ubifs versions

Confusion over mkfs.ubifs versions

[David Lambert]

After upgrading to Ubuntu 10.10 I noticed that the stock mkfs.ubifs 
(version 1.3) failed to compute checksums correctly. I compiled my own 
version from the git source of mtd-utils which announces itself as 
version 1.4; this worked fine. Being curious I logged onto a machine 
running Ubuntu 10.4 and checked the version of mkfs.ubifs and also found 
it to be 1.3, but this version computes checksums correctly! Is there a 
sub-version of mkfs.ubifs between 1.3 and 1.4 that is not shown by using 
--version? Am I missing something critical here?

Regards,

Dave.

There was a time period a few months ago (not very specific, sorry)
when mkfs.ubifs checksums were indeed broken.

Unfortunate if the Ubuntu 10.10 stock version has that bug :/

Not tried it myself, though just put Ubuntu 10.10 on a machine here
and might be using it for dev so I'll bear that in mind. Thanks.

Since mtd-utils are not managed very well, and we were not tagging them
regularly enough, I think Ubuntu guys just picked a non-tagged snapshot
which had that bug. Just take newer version please, or ask Ubunto folks
to do this.
