Combined changes to allow experimentation with net 0/8 (network 0),
240/4 (Experimental/"Class E"), and part of the loopback net 127/8
(all but 127.0/16). All changes are disabled by default, and can be
enabled by the following sysctls:
net.inet.ip.allow_net0=1
net.inet.ip.allow_net240=1
net.inet.ip.loopback_prefixlen=16
When enabled, the corresponding addresses can be used as normal
unicast IP addresses, both as endpoints and when forwarding.
Add descriptions of the new sysctls to inet.4.
Add <machine/param.h> to vnet.h, as CACHE_LINE_SIZE is undefined in

In preparation for removing OBJT_DEFAULT, eliminate some stale/unhelpful
comments from vm_mmap(), and remove an unused case. In particular, the
remaining callers of vm_mmap() in the tree do not specify OBJT_DEFAULT.
It's much more common to use vm_map_find() to map an object into user
memory, so rather than adjusting vm_mmap() to handle OBJT_SWAP objects,
let's further discourage its use and simply remove OBJT_DEFAULT
handling.

55abf23dd3 inverted the value passed to origin_subst_one when rolling
up the existing code into a loop. If the first token is found ($ORIGIN),
this results in a wild free of part of strtab. Processing the second
token works fine and will act how the first should have regardless of
whether found, allocating memory for the string without freeing.
Processing subsequent tokens however will then leak, regardless of
whether found, as they will also believe they need to allocate memory
and can't free the string.

Commit 981ef32230 added optional use of the session
slots marked bad to recover a new session when all
slots are marked bad. The recovery worked against
a FreeBSD NFSv4.1/4.2 server, but not a Linux one.
It turns out that it was a bug in the FreeBSD client
and not the Linux server.
This patch fixes the client so that DeleteSession
followed by CreateSession after receiving a
NFSERR_BADSESSION error reply works against the
Linux server (and conforms to the RFC).
This also implies that the FreeBSD NFSv4.1/4.2
server needs to be fixed in a future commit.
Without the fix, the FreeBSD server does a full
recovery, including creation of a new ClientID,
but since "intr" mounts were broken, this does
not result in a regression.
This patch only affects the case where a CreateSession
is done for an already confirmed ClientID, which was
not being done prior to commit 981ef32230.

uma_timeout() has several responsibilities; it visits every UMA zone and
as of recently will drain underutilized caches, so is rather expensive
(>1ms in some cases). Currently it is executed by softclock threads
and so will preempt most other CPU activity. None of this work requires
a high scheduling priority, though, so defer it to a taskqueue so as to
avoid stalling higher-priority work.

In handleevents(), lock the timer state before fetching the time for the
next event. A concurrent callout_cc_add() call might be changing the
next event time, and the race can cause handleevents() to program an
out-of-date time, causing the callout to run later (by an unbounded
period, up to the idle hardclock period of 1s) than requested.
In cpu_idleclock(), call getnextcpuevent() with the timer state mutex
held, for similar reasons. In particular, cpu_idleclock() runs with
interrupts enabled, so an untimely timer interrupt can result in a stale
next event time being programmed. Further, an interrupt can cause
cpu_idleclock() to use a stale value for "now".
In cpu_activeclock(), disable interrupts before loading "now", so as to
avoid going backwards in time when calling handleevents(). It's ok to
leave interrupts enabled when checking "state->idle", since the race at
worst will cause handleevents() to be called unnecessarily. But use an
atomic load to indicate that the test is racy.

Commit 981ef32230 enabled marking of potentially bad
session slots when an RPC is interrupted if the "intr"
mount option is used. As such, it no longer makes
sense to call nfscl_hasexpired() for I/O operations that
reply NFSERR_BADSTATEID for NFSv4.1/4.2, which does a full
recovery of NFSv4 open state, destroying all byte range locks.
Recovery of open state should not be usually needed, since
the session slot has been marked potentially bad and,
although opens for the process that has been terminated via
a signal may be broken, locks for other processes will still
be valid.
This patch disables calls to nfscl_hasexpired for NFSv4.1/4.2
mounts, when I/O RPCs receive NFSERR_BADSTATEID replies.
It does not affect the behaviour of NFSv4.0 mounts nor
hard (non "intr") mounts.

To deal with broken session slots caused by the use of the
"soft" and/or "intr" mount options, nfsv4_sequencelookup()
has been modified to track the potentially broken session
slots (commit 40ada74ee1). Then, when all session slots
are potentially broken, nfsv4_sequencelookup() does a
DeleteSession operation, so that the NFSv4.1/4.2 server will
reply NFSERR_BADSESSION to uses of the session.
The client will then recover by doing a CreateSession to
acquire a new session.
This patch adds the code that marks potentially bad
slots, so that the above semantics become functional.
It has been successfully tested against a FreeBSD
NFSv4.1/4.2 server, but does not work against a Linux 5.15
NFSv4.1/4.2 server. (The Linux 5.15 server creates
a new session with the same sessionid as the destroyed
one and, as such, keeps returning NFSERR_BADSESSION.
I believe this is a bug in the Linux server.)
However, this should not cause a regression and will
make "intr" mounts fairly usable against the NFSv4.1/4.2
servers where it works.

Currently, processing of IPv6 local traffic is partially broken:
link-local connection fails and global unicast connect() takes
3 seconds to complete.
This happens due to the combination of multiple factors.
IPv6 code passes original interface "origifp" when passing
traffic via loopack to retain the scope that is mandatory for the
correct hadling of link-local traffic. First problem is that the logic
of passing source interface is not working correcly for TCP connections,
resulting in passing "origifp" on the first 2 connection attempts and
lo0 on the subsequent ones. Second problem is that source address
validation logic skips its checks iff the source interface is loopback,
which doesn't cover "origifp" case.
More detailed description is available at https://reviews.freebsd.org/D35732
