autofs-5.1.5 - Fix NFS mount from IPv6 addresses
From: Goldwyn Rodrigues <rgoldwyn@suse.de>
When an NFS server is specified by an IPv6 address and no mount
options, the mount fails because check_address_proto()
receives vers with TCP_REQUESTED set but the host.addr_len is
INET6_ADDRSTRLEN. Removing the check for INET_ADDRSTRLEN
fixes this issue.
However, this will allow mount from "proto=tcp" for an IPv6
addressed server.
Fixes: 9053214 ("autofs-5.1.3 - fix ipv6 proto option handling")

autofs-5.1.5 - support strictexpire mount option
From: Ian Kent <raven@themaw.net>
Kernel commit 092a53452b (("autofs: take more care to not update
last_used on path walk") helped to (partially) resolve a problem
where automounts were not expiring due to aggressive accesses from
user space.
This patch was later reverted because, for very large environments,
it meant more mount requests from clients and when there are a lot
of clients this caused a fairly significant increase in server load.
But there is a need for both types of expire check, depending on use
case, so a mount option to allow for strict update of last use of
autofs dentrys has been added ito the autofs file system (which just
means not updating the last use on path walk accesses).
So add support for this master map mount entry option in the user
space code.

autofs-5.1.5 - fix hesiod string check in master_parse()
From: Ian Kent <raven@themaw.net>
When map source is specified in a master map entry, checking if
map type is hesiod in master_parse() will generate a SEGV if a
parser type is not also present becuase tmp will be NULL in this
case.
