freebsd-update compares the dates on man pages with mandoc.db, and if
any newer pages are found it regenerates mandoc.db.
Previously, if mandoc.db did not already exist the check failed and
freebsd-update then failed to create one. Now, check that mandoc.db
exists before performing the check for newer pages.

If the root file system is composed from multiple devices, wait for
devices to be ready before running zpool and dumpon rc scripts.
An example of this is if the bulk of the root file system exists on a
fast device (e.g. NVMe) but the /var directory comes from a ZFS dataset
on a slower device (e.g. SATA). In this case, it is possible that the
zpool import may run before the slower device has finished being probed,
leaving the system in an intermediate state.
Fix is to add root_hold_wait to the zpool and dumpon (which has a
similar issue) rc scripts.

before this change pf_route operated on the semantic that pf runs
when packets go over an interface, so when pf_route changed which
interface the packet was on it would run pf_test again. this change
changes (restores) the semantic that pf is only supposed to run
when packets go in or out of the network stack, even if route-to
is responsibly for short circuiting past the network stack.
just to be clear, for normal packets (ie, those not touched by
route-to/reply-to/dup-to), there isn't a difference between running
pf when packets enter or leave the stack, or having pf run when a
packet goes over an interface.
the main reason for this change is that running the same packet
through pf multiple times creates confusion for the state table.
by default, pf states are floating, meaning that packets are matched
to states regardless of which interface they're going over. if a
packet leaving on em0 is rerouted out em1, both traversals will end
up using the same state, which at best will make the accounting
look weird, or at worst fail some checks in the state and get
dropped.
another reason for this commit is is to make handling of the changes
that route-to makes consistent with other changes that are made to
packet. eg, when nat is applied to a packet, we don't run pf_test
again with the new addresses.
the main caveat with this diff is you can't have one rule that
pushes a packet out a different interface, and then have a rule on
that second interface that NATs the packet. i'm not convinced this
ever worked reliably or was used much anyway, so we don't think
it's a big concern.
discussed with many, with special thanks to bluhm@, sashan@ and
sthen@ for weathering most of that pain.

Commit 01ae8969a9 stopped the NFSv4.1/4.2 server from implicitly
binding the back channel to a new TCP connection so that it
conforms to RFC5661, for NFSv4.1/4.2. An effect of this
for the Linux NFS client is that it will do a
BindConnectionToSession when it sees NFSV4SEQ_CBPATHDOWN
set in a sequence reply. This will fix the back channel, but the
first attempt at a callback like CB_RECALL will already have
failed. Without this patch, a CB_RECALL will not be retried
and that can result in a 5 minute delay until the delegation
times out.
This patch modifies the code so that it will retry the
CB_RECALL every couple of seconds, often avoiding the
5 minute delay.
This is not critical for correct behaviour, but avoids
the 5 minute delay for the case where the Linux client
re-binds the back channel via BindConnectionToSession.

Several large data structures are allocated by fsck_ffs to track
resource usage. Most but not all were deallocated at the end of
checking each filesystem. This commit consolidates the freeing
of all data structures in one place and adds one that had previously
been missing.
It is important to clean up these data structures as they can be
large. If the previous allocations have not been freed, fsck_ffs
can run out of address space when many large filesystems are being
checked. An alternative would be to fork a new instance of fsck_ffs
for each filesystem to be checked, but we choose to free the small
set of large structures to save the fork overhead.

The VFS conventions is that VOP_LOOKUP() methods do not need to handle
ISDOTDOT lookups for VV_ROOT vnodes (since they cannot, after all). Nullfs
bypasses VOP_LOOKUP() to lower filesystem, and there, due to user actions,
it is possible to get into situation where
- upper vnode does not have VV_ROOT set
- lower vnode is root
- ISDOTDOT is requested
User just needs to nullfs-mount non-root of some filesystem, and then move
some directory under mount, out of mount, using lower filesystem.
In this case, nullfs cannot do much, but we still should and can ensure
internal kernel structures are consistent. Avoid ISDOTDOT lookup forwarding
when VV_ROOT is set on lower dvp, return somewhat arbitrary ENOENT.
