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-5.1.6 - fix empty mounts list return from unlink_mount_tree()
From: Ian Kent <raven@themaw.net>
If there are no appropriate mounts found by get_mnt_list() then
unlink_mount_tree() should return 1 not 0 since if there are no
mounts to umount this shouldn't cause a failure return.
Also, if a real error occurs in get_mnt_list() we should check for
it and return a failure from unlink_mount_tree() since that would
be mount table not found or out of memory. If that's ignored things
would only get worse from that point.

autofs-5.1.7 - eliminate buffer usage from handle_mounts_cleanup()
From: Ian Kent <raven@themaw.net>
This buffer was originally added because a SEGV was seen accessing
the ap->path field on shutdown.
But this was actually caused by calling master_remove_mapent() too
early which adds the map entry to the master map join list that leads
to freeing the autofs_point (ap in the code) which also frees ap->path.
But the master map join list is protected by the master map mutex which
is held until after all the accesses are completed. So whatever the
problem was it doesn't appear to be present any more.
Nevertheless, to be sure, delay the call to master_remove_mapent() until
after all accesses to ap->path are completed.

autofs-5.1.7 - eliminate redundant cache lookup in tree_mapent_add_node()

Since we need to create the offset tree after adding the offset entries
to the mapent cache (from a list.h list) there's no need to lookup the
mapent in tree_mapent_add_node() and validate it. Just use it directly
when calling tree_mapent_add_node() and avoid a cache lookup on every

autofs-5.1.7 - fix concat_options() error handling
From: Ian Kent <raven@themaw.net>
There's a possibility of a memory leak in the mount options processing
when calling concat_options() in parse_mount() of the Sun format map
entry parsing.
There's also a case in do_init() of the Sun map format parsing where
a previously freed value is used in a logging statement without being
set to MULL.
So ensure concat_options() always frees it's arguments so that the
handling can be consistent in all places.

autofs-5.1.7 - fix hosts map offset order
From: Ian Kent <raven@themaw.net>
Map entry offset paths to be in shortest to longest order but exports
from a server could come in any order. If there are a large number of
exports this can result in a lot of overhead when adding the offset
to the ordered list use to mount the offset during parsing since the
path length of exports can cary a lot.
So leverage the tree implemention to sort the export offsets into
shortest to longest order as we go when constructing the mapent from
the exports list.

autofs-5.1.7 - fix lookup_prune_one_cache() refactoring change
From: Ian Kent <raven@themaw.net>
Commit 256963d6b (autofs-5.1.7 - refactor lookup_prune_one_cache() a bit)
changed the position of the getting the next enumeration map entry but
failed to update a couple of other locations that assume the next map
entry has been set. Under certain fairly common conditions this leads
to an infinite loop.

autofs-5.1.7 - fix nonstrict offset mount fail handling
From: Ian Kent <raven@themaw.net>
If a triggered offset mount fails automount is not handling nonstrict
mount failure correctly.
The nonstrict mount failure handling needs to convert an offset mount
failure to a success if the offset subtree below the failed mount is not
empty otherwise it must return the failure. The previous implementation
used -1 to indicate the subtree was empty and that was used to detect
when the mount should fail instead of converting the fail to a success.
Make the new implementation do the same.

autofs-5.1.7 - fix offset entries order
From: Ian Kent <raven@themaw.net>
While it's rare it's possible that a mapent entry might not have
it's offsets in shortest to longest path order.
If this happens adding an entry to the mapent tree can result in
an incorrect tree topology that doesn't work. That's because adding
tree entries ensures that nodes in a sub-tree are placed below the
containing node so the containing node must be present for that to
work. This topology is critical to the performance of map entries
that have a very large number of offsets such as an NFS server with
many exports.
There's no other choice but make a traversal after the offset entries
have all been added to create the mapent tree.

autofs-5.1.8 - allow -null map in indirect maps
From: Ian Kent <raven@themaw.net>
We have had reports of GUI programs (such as Nautilus) probing for files
such as .hidden in the parent directory of the directory being accessed.
If using an indirect mount map with a wildcard map entry autofs is duty
bound to try and mount these which usually results in a mount failure but
can also cause lengthy delays in some cases.
There are some challenges to modifying application code and even if it
can be done it's always open to being broken later by developers that
aren't aware of the reasoning behind the original changes.
Now, there is a machanism in autofs that can be used to ignore certain
map entries, the "builtin map -null", see auto.master(5). Currently it
can be used only in the master map but this change extends it to be used
in indirect mount maps as well. In this way it can be used to handle
problematic entries by simply adding a map entry that uses the builtin
-null map.
For example:
.hidden -null
* someserver:/remote/home/&
This mechanism is not standard so if one is using systems other than
those with Linux autofs and central map storage, such as LDAP, then
it would be necessary to configure nsswitch to ensure the files map
source is consulted first followed by the remote map source. Then the
-null map entries included in a local file map that uses plus map
inclusion to move on the the central map source if there is no match.
For example, in /etc/auto.home we can have:
.hidden -null
+auto.home

autofs-5.1.8 - continue expire immediately after submount check
From: Ian Kent <raven@themaw.net>
The expire proc for both direct and indirect mounts doesn't immediately
continue after seeing an autofs submount and sending it a notification.
Add the "continue" to avoid some wasted overhead.

autofs-5.1.8 - don't close lookup at umount
From: Ian Kent <raven@themaw.net>
Since map sources are reference counted they persist beyond autofs
submounts.
Now the map source moudule lookup gets closed at submount umount and
if we are unlucky enough to be using the same map in other submounts
and a lookup is underway at the time of the umount a crash can occur.
To resolve this it's much better to just not close the lookup at
submount umount and rely on the map source free to close the module
lookup and instances when the map source is no longer referenced.

There's a delay on expire of submounts that can be as much as the

autofs-5.1.8 - dont use initgroups() at spawn
From: Ian Kent <raven@themaw.net>
The initgroups(3) function isn't safe to use between fork() and
exec() in a threaded program.
Using it this way often leads to a hang for even moderate work
loads.
But the getgrouplist()/setgroups() combination can be used safely
in this case and this patch changes autofs to use these (the safety
of using of setgroups() is yet to to be documented).
A large portion of the work on this patch has been contributed
by Roberto Bergantinos <rbergant@redhat.com>.

autofs-5.1.8 - eliminate last remaining state_pipe usage
From: Ian Kent <raven@themaw.net>
Eliminate the last remaining usage autofs mount struct state_pipe that
is used when changing state to ST_SHUTDOWN at submount exit. Ths single
usage consumes a pipe file handle pair for every autofs file system
mount.

autofs-5.1.8 - fix deadlock with hosts map reload
From: Ian Kent <raven@themaw.net>
When reloading maps the hosts map calls lookup method ->parse_mount()
for each multi-mount root entry in the map (each host) while holding
the cache read lock which leads to a cache lock deadlock.
Remove the need to hold the cache read lock by creating an independent
list of entries for the update so the lock doesn't need to be taken.

autofs-5.1.8 - fix expire retry looping
From: Ian Kent <raven@themaw.net>
Commit aa6da48d1 (autofs-5.1.7 - eliminate count_mounts() from
expire_proc_indirect()) stopped using the count_mounts() function
in indirect mount expires because it can be a significant overhead
and shouldn't be needed if the kernel expire dentry selection works
as it should.
Unfortunately there is a case where it doesn't work properly, when
a USR1 signal is sent to the automount process it is meant to expire
mounts regardless of the expire timeout. In this case if a mount has
been propagated to a mount namespace and is held busy the mount will
fail to umount and because setting the last used field of the mount
dentry doesn't prevent the mount dentry from being selected for expire
again immediately in this case automount will look continually.
The problem occurs because the the kernel doesn't know how to check
these propagated mounts for busyness and the init namespace automount
process tries to expire the mount but fails and continues trying to
expire the mount because the expire function assumes only mounts that
are not busy will be selected for expire.

autofs-5.1.8 - fix fix mount tree startup reconnect
From: Ian Kent <raven@themaw.net>
In function master_mount_mounts() commit 635b90eccee9 checks if the
current top level mount is already running by using two things, if the
mount handling thread id is set in the autofs mount point structure and
if the mount point path is a mounted autofs file system.
But the top level master map entry for a direct mount map is the
reserved path "/-" and doesn't have an actual mount associated with it
so a mounted check can't be used. But we know that top level mounts
start in state ST_INIT and once that state is changed it never changes
back to it. So using the presence of the mount handling thread id and
the state not being ST_INIT is sufficient to know if this is a new
mount or not.

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 hosts map deadlock on restart
From: Ian Kent <raven@themaw.net>
When starting automount(8) with a hosts map that has mounts that were
in use at the last exit a deadlock can occur.
In this case automount(8) will perform the same steps but not actually
perform the mount to re-construct the context of each mount. But, with
the hosts map, that leads to calling back into the sun parse module
while holding the map module read lock which will again try and take
the write lock.
Fix this by only taking the write lock in the mount code path if the
module handle has not already been opened.

autofs-5.1.8 - fix incorrect matching of cached wildcard key
From: Ian Kent <raven@themaw.net>
During the implementation of amd format map entry support the code
to match a cached key was modified.
Unfortunately there's a case were the key lookup behaves incorrectly.
That case is when there are included maps in the map itself and one
of the maps (usually the last) has a wildcard key entry. In this case
the wildcard key may be found during lookup but the map it blongs to
isn't checked so it can be incorrectly returned instead of a matching
entry in a subsequent included map.
Another problem case is when there's a wildcard match and a cache prune
occurs while the mount is being done. In this case the matched cache
entry that has been added is seen as stale and removed along with the
mount point directory during the prune leading to a mount fail.

autofs-5.1.8 - fix invalid tsv access
From: Ian Kent <raven@themaw.net>
When using the --dumpmaps option of automount(8) a SEGV can occur
because a thread specific data variable accessed in the code hasn't
yet been created.
The thread specific data doesn't need to be set to list the maps
so we can create the key and rely on pthread_getspecific() returning
NULL when the value hasn't been set as this case is handled correctly.

autofs-5.1.8 - fix mount tree startup reconnect
From: Ian Kent <raven@themaw.net>
When reconnecting to an existing mount tree at startup trying to work
out if we created the mountpoint directory uses the parent path of the
current map entry.
But if the current map entry has no parent we should use the map entry
path.

When checking if a mount location is a multi-mount after the first location
the next '-' or '/' indicates it's a multi-mount.

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.

autofs-5.1.8 - make amd mapent search function name clear
From: Ian Kent <raven@themaw.net>
When looking for amd sections in the configuration the function to
find mount entries is not named so it is clear what it's trying to
do so change its name. Also make it static since it is called only
once in the same source file.

autofs-5.1.8 - make signal handling consistent
From: Ian Kent <raven@themaw.net>
There's a mixture of usage of sigprocmask() and pthread_sigmask(), change
to use the pthread versions of this for correctness.
The only exception to this is reset_signals() which is done in a forked
process that is single threaded so it's valid to keep them as they are.

autofs-5.1.8 - make submount cleanup the same as top level mounts
From: Ian Kent <raven@themaw.net>
We often see segfaults when cleaning up resources at submount shutdown
after changes are made to resolve problems. It's always really hard to
work out what's causing these to happen.
But changing submounts to use the same final cleanup method as top level
mounts eliminates the faulting, at least in the case of the most recent
changes, hopefully this change in proceedure will continue to work.
Admitedly there's some setting of fields to NULL after freeing but that
didn't fix the problem until the procedure change was also made.
In any case the result is a consistency improvement.

autofs-5.1.8 - remove redundant stat from do_mount_direct()
From: Ian Kent <raven@themaw.net>
In do_mount_direct() a stat() call is used to check mount point
attributes but the fstat() of the ioctlfd is for the same path so
the lower overhead fstat() call can be used to do these checks as
well.

autofs-5.1.8 - use device id to locate autofs_point when setting log priotity
From: Ian Kent <raven@themaw.net>
Using a fifo pipe for every autofs mount to dynamically set the log
priority is expensive in terms of the number of file handles used.
It would be better to use a single file handle and locate the autofs
mount point by it's id to set the log priority.
Start by making the communication pipe send the device id as well as
the log priority to be set and use the newly added helper function
master_find_mapent_by_devid() to locate the autofs mount to change the
log priority.

we could be iterating through the map entries with the cache readlock
held so we can't just take the writelock for direct mounts. But when

autofs-5.1.9 - fix get parent multi-mount check in try_remount()
From: Ian Kent <raven@themaw.net>
In commit 635b90ecc (autofs-5.1.8 - fix mount tree startup reconnect)
when getting the parent the check for a multi-mount should include a
check for the root of the multi-mount as well since the root does not
set its parent (it remains NULL).
We could set the root parent to itself but that may have side effects
because the convention has always been the parent is NULL for the
multi-mount root.
