fs/udf and udftools

fs/udf and udftools

[Steve Kenton]

Is anyone maintaining these or am I about to volunteer for another job?

I'm having to dig into fs/udf and udftools/mkudffs as part of a project I'm working on.
It looks like both have been lacking in personal TLC for quite a while. The changes to
fs/udf seem to be tree wide VFS work but not updates to things like write support and
udftools seems to have been frozen for >10  years. Both ~work but I'd like to fix an
oops I'm getting in udftools and work on adding fallocate() support to fs/udf and then
feed it back to the community rather than let the changes bit rot locally.

Where to go from here? I've been reading LKML on marc: for years, mainly to see what Linus,
Al and a variable group of other people say/do but I've never done more than tinker with
the kernel locally. I'm using git for the project mentioned above but again am not an
expert but willing to learn. I'm not currently subscribed so please cc me if you could.

A bit of googling for udftools suggests that gentoo are maintaining
their build, debian have patches for gcc-4 and gcc-5 among others,
Fedora have their own patches, and Arch have some patches (which
might be the same as some of hte others, I did not look).

Looks like the normal "possibly abandonned, but still useful to some
people" software, where distros keep it building.

There may also be others.

I guess I should have said "developing" rather than "maintaining" for
fs/udf since it's clear that someone has been keeping it running in-tree.
I started with udftools from source forge and then discovered that the
kernel udf driver does not support fallocate() which I was hoping to use.

Thanks for the pointer to Jan Kara. I'll see how he feels about patches
from the wilderness.

Yes, that's where I started. The last release was 1.0.0b3 in 2004.
Which is what the Ubuntu 14.04LTS package reports as it's version too.

Yep, that's where my ~works came from.
Ah, thanks for the links. I'll pull them all together and see what's there.

So I don't have too much time for UDF. That's why I mostly fix bugs someone
reports, occasionally improve stuff or review patches others send but I
don't have time for development of new features for UDF.

Pali Rohar has recently startted a repo on github for udftools. It is at
https://github.com/pali/udftools

So userspace patches go to him.

OK, I'll see what I can do and try not to bother you until stuff is working well.

Perfect! All of my googling  pointed to source forge but this is what I was hoping for.
