autofs-5.0.4 - always read file maps key lookup fixes
From: Ian Kent <raven@themaw.net>
Since we always read file maps at start we need to ensure that
we return a not found if the key isn't found in the cache. Also,
if we're looking through a "multi" map we can't use the cache
lookup optimisation because, in this case, there is a single map
source shared by the "multi" maps so we may not get correct results
from the lookup if a map later in the search has been modified.

autofs-5.0.4 - always read file maps multi map fix
From: Ian Kent <raven@themaw.net>
Since "multi" map entries may contain file maps themselves and we
always want to read file maps we need to move the chack of whether
to read the map from lookup_nss_read_map() into the individual
map type lookup modules.

autofs-5.0.4 - dont fail on ipv6 address adding host
From: Ian Kent <raven@themaw.net>
We don't have IPv6 support enabled in libtirpc yet. When we
perform name (or address) lookup and we get a mixture of IPv4
and IPv6 addresses the lack of IPv6 support can cause the
parse_location() function to fail to add any valid hosts when
in fact it should.

autofs-5.0.4 - dont umount existing direct mount on master re-read
From: Ian Kent <raven@themaw.net>
Since direct mounts can have multiple entries in the master map they each
have an instance associated with them. If one entry changes, such as the
mount options, the instance comparison test fails and a new instance is
added. This causes autofs to get confused because there are now two
entries that contain the same mount information in different internal
caches. There are several consequences of this, most of which are just
noise in the log, but it also causes confuion for the expiration of mounts
since, for an active mount, the old cache entry can't be pruned until it's
umounted. Also, the map caches were not being properly pruned.

autofs-5.0.4 - fix kernel includes
From: Valerie Aurora Henson <vaurora@redhat.com>
autofs_dev-ioctl.h is included by both the kernel module and autofs,
and it includes two kernel header files. The compile worked if the
kernel headers were installed but failed otherwise.
imk: there are a couple of other instances were we include kernel
headers. I've tried to fix that up too.

autofs-5.0.4 - improve manual umount recovery
From: Ian Kent <raven@themaw.net>
The check for manually umounted mounts in the expire of direct mounts is
racy and the check itself is inadequate in that it can incorrectly clear
the descriptor of an active mount. Also, we do a similar test following
the expire which is a waste since we can catch this on the next expire.
So these two tests have been combined and the check done only prior to
the expire. In the indirect expire we don't have a check at all so we
add one.

autofs-5.0.4 - library reload fix update fix
From: Ian Kent <raven@themaw.net>
The library reload fixes introduced a bug which causes autofs to
incorrectly shutdown. Previously the signal handling thread only
recieved signals either when they were explicity sent or it was
time to shutdown so continuing on to call the signal handling
routine was the correct thing to do. Now we need to join with
the mount handling thread at exit but, in this case, we don't
want to continue on to the signal handling routine as that will
incorrectly cause the signal to be passed on to other mount
handling threads.
