Re: HEADS UP: UFS2 extended attribute changes will be committed tomorrow



Hello Chuck,

In my records, I noticed another note that I had made more than a year ago.
That was around the time the Posix ACLs were imported into NetBSD. I'm not
sure if this is on anyone's radar, or if it's generally considered a
requirement. I would be interested to know how dump / restore are affected
by the current changes, or if there are plans to add support for Extended
Attributes / ACLs to them. Back in FreeBSD 6.0 times there was a patch[1]
that did exactly that for the FreeBSD variants of dump / restore. Probably
the source code deviates however far from it.

christos applied the dump changes for extattrs from freebsd to our code last year:

commit 52fea75266aee4480e62dd763d4d3d74b002ea5c
Author: christos <christos%NetBSD.org@localhost>

     Add external attribute dumping and restoring support from FreeBSD.
     Does not fully work yet, attributes are being saved and restored correctly,
     but don't appear in the restored files somehow.


there is a bug in that code that effectively prevents restoring NFSv4 ACLs.
I have a fix for this bug that I need to apply to freebsd and then I'll apply it
to our code as well.


thanks for the update. I have seen the fix has landed in NetBSD code base earlier this week - great job! ACL support in NetBSD becomes more and more complete & solid :-)

Kind regards
Matthias
