autofs-5.1.4 - make umount_ent() recognise forced umount
From: Ian Kent <raven@themaw.net>
When doing a forced shutdown umount_ent() tries a normal expire
first resulting in a fair amount of unnecessary log noise.
Change umount_ent() to do a forced expire when a forced shutdown
has been requested to avoid the log noise.

autofs-5.1.6 - fix double quoting in auto.smb
From: Ian Kent <raven@themaw.net>
The example program mount script installed to /etc/auto.smb incorrectly
adds a quote for the trailing dollar of special Windows mounts. But they
are already surrounded by double quotes. This may have been handled by
mount.cifs at some point but it's failing now.

autofs-5.1.8 - fix handling of incorrect return from umount_ent()
From: Ian Kent <raven@themaw.net>
Commit 0210535df4b ("autofs-5.1.0 - gaurd against incorrect umount
return") guards against umount_ent() returning a fail when the mount
has actually been umounted.
But we also see umount_ent() return success when in fact the mount has
not been umounted leading to incorrect handling of automounts.
So checking the return of umount_ent() isn't always giving the correct
result in more than just one case, consequently we should ignore the
result from the spawned umount(8) and check if the mount has in fact
been umounted.

autofs-5.1.8 - fix kernel mount status notification
From: Ian Kent <raven@themaw.net>
The status return for attempted mount notification is not done
correctly in some cases leading to a status being sent to the
kernel multiple times or the send causing an error.
We must send a status to the kernel but it needs to be the correct
one. It definitely shouldn't be sent twice for the same mount attempt
and shouldn't be failing.

autofs-5.1.8 - fix root offset error handling
From: Ian Kent <raven@themaw.net>
If mounting the root or offsets of a multi-mount root fails any mounts
done so far need to be umounted and the multi-mount offset tree deleted
so it can be created cleanly and possibly mounted the next time it's
triggered.
Also, if a subtree that is not the multi-mount root fails the expire
alarm needs to be re-instated so other subtrees (at least the root)
will continue to expire.

autofs-5.1.8 - fix set open file limit
From: Ian Kent <raven@themaw.net>
The check of whether the open file limit needs to be changed is not
right, it checks the hard open file limit against what autofs wants
to set it to which is always less than this value. Consequently the
open file limit isn't changed.
autofs should be changing only the soft open file limit but it is
setting both the hard and soft limits. The system hard limit is much
higer than the autofs maximum open files so the hard limit should be
left alone.
While we are here increase the requested maximum soft open file limit
to 20k.

because if a real mount at the base of a sub-tree fails to umount all
we can do is re-instate the offset mounts under it which must succeed
for the mount tree to remain useful.
