Hi folks,
Some of you may remember my posting of a new way to do autofs in Linux a
while back:
http://marc.theaimsgroup.com/?l=linux-kernel&m=107341940326348&w=2
Anyhow, I've gotten to the point where I have code that people can play
with. I've posted it all at http://autofsng.bkbits.net
There are two repos located there, one is the userspace bits (autofsng).
~ It has the 'utility' (automount) and the autofs usermode agent
(autofs). This tree began as a automount 3.1.7 tree, but has
drastically changed. Lots of good stuff has yet to be merged in from
the automount 4 daemon.
The kernel bits are in the linux-2.6-autofsng repository. Broken out
patches are forthcoming in the next (weeks?) [*]. It has the following
major changes to it:
- - changes to the vfsmount tree structures so that you can detach and
re-attach sub-trees of the vfsmount tree. The current implementation is
admittedly a bit gross and will require work to make it pretty (and to
get rid of having to grab a rwlock on every mntget/mntput!).
- - the addition of a mountpoint file descriptor api. I don't care for
the interface at the moment, and I'll be posting interface descriptions
later on along with broken out patches so that the interface itself can
be thought through.
- - vfs native support for expiring mountpoints (and entire subtrees of
them). There currently exists a syscall entry to specify this from
userspace as a way to easily test it. As well, you can specify expiry
information using the above mountpoint file descriptor api.
- - a new module implementing the 'autofs' filesystem called autofsng.
This filesystem will support automounting of both direct and indirect
maps. It also supports 'browsing'. Most of this magic happens using
'->follow_link' walks on directory inodes. This is ugly, but it
appears to be the best way to properly handle automounting from within
the kernel.
There does remain a good amount of work to do, and I've tried to list
things on the top of my head in the autofsng/autofs/TODO file. I'm sure
I missed stuff :\
At this point, I can run and pass a ported autofs connectathon
testsuite. I'm working on figuring out how to get the testsuite
included in the package. For comparison, both autofs3 and autofs4
couldn't handle the majority (>%95) of the tests done. As well, we've
uncovered a couple of nfs related issues that we'll be following up with
on the nfs list.
So, if you have time to spare and you care about automounting, please
have a try at using it. If you are curious enough to wade through it,
feel free to give feedback/flames/comments on the code/design/weather.
Thanks,
[*] - I know it is bad practice to pop-up out of nowhere with large
changes, but I wasn't able to get anything out much earlier due to a
variety of reasons. From now on, expect to see much traffic from me as
I feed a broken-out patchsets to the list.

Although I am certainly a BK fan, please do post non-BK sources
somewhere so people can review and poke at them...

autofsng userland tarball and kernel patch can now be found
