nfsd: Fix CreateSession for an established ClientID
I mis-read the RFC w.r.t. handling of the sequenceid
when a CreateSession is done after the initial one
that confirms the ClientID. Fortunately this does
not affect most extant NFSv4.1/4.2 clients, since
they only acquire a single session for TCP for a
ClientID (Solaris might be an exception?).
This patch fixes the server to handle this case,
where the RFC requires the sequenceid be incremented
for each CreateSession and is required to reply to
a retried CreateSession with a cached reply.
It adds a field to nfsclient called lc_prevsess,
which caches the sessionid, which is the only field
in a CreateSession reply that will change for a
retry, to implement this reply cache.
The recent commits up to d4a11b3e3bdd that mark
session slots bad when "intr" and/or "soft" mounts
are used by the client needs this server patch.
Without this patch, the client will do a full
recovery, including a new ClientID, losing all
byte range locks. However, prior to the recent
client commits, the client would hang when all
session slots were bad, so even without this
patch it is not a regression.

nfscl: Fix CreateSession for an established ClientID
Commit 981ef32230b2 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 981ef32230b2.

nfscl: Do not call nfscl_hasexpired() for NFSv4.1/4.2
Commit 981ef32230b2 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.

nfscl: Enable detection of bad session slots
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 40ada74ee1da). 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.

In handleevents(), lock the timer state before fetching the time for the

In cpu_idleclock(), call getnextcpuevent() with the timer state mutex

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

This is because ipfw_init_sopt_handler() and ipfw_destroy_sopt_handler()
are declared with (void) argument lists, but defined with empty argument
lists. Make the definitions match the declarations.
With clang 15, the following -Werror warnings are produced:
sys/dev/hwpmc/hwpmc_mod.c:4805:6: error: variable 'nfree' set but not used [-Werror,-Wunused-but-set-variable]
int nfree;
^
sys/dev/hwpmc/hwpmc_mod.c:4804:6: error: variable 'ncallchains' set but not used [-Werror,-Wunused-but-set-variable]
int ncallchains;
^
The 'nfree' and 'ncallchains' variables were used in KASSERTs, but these
were removed due to refactoring in d9f1b8dbf29d. Remove the variables
since they no longer serve any purpose.
Adjust tdsaContext_t::NvmdResponseSet declaration to avoid clang 15 warning
With clang 15, the following -Werror warnings are produced:
In file included from sys/dev/pms/freebsd/driver/ini/src/agtiapi.c:70:
sys/dev/pms/RefTisa/tisa/sassata/common/tdsatypes.h:346:13: error: type specifier missing, defaults to 'int'; ISO C99 and later do not support implicit int [-Wimplicit-int]
volatile NvmdResponseSet;
~~~~~~~~ ^
int
The NvmdResponseSet member is effectively only used as a boolean in the
pms(4) driver, so it could be a single bit. But to avoid changing the
semantics at all in this unmaintained driver, simply declare it as a
volatile int.
Adjust pcmlog_{initialize,shutdown}() definitions to avoid clang 15 warning

nfscl: Fix setting of nfsess_defunct for nfscl_hasexpired()
Commit a7bb120f8b87 added a printf for the case where recovery
has not marked the session defunct by setting nfsess_defunct
to 1. It turns out that nfscl_hasexpired() calls
nfsrpc_setclient() directly, without setting nfsess_defunct.
This patch replaces the printf with code that sets
nfsess_defunct to 1 to handle this case.
If SIGTERM is issued to a process when it is doing I/O on
an "intr" mount, the NFSv4 server may reply NFSERR_BADSTATEID,
due to the Open being prematurely closed.
This can result in a call to nfscl_hasexpired() to do a
recovery.
This would explain at least one hang described in the PR.
Adjust nvd_{load,unload}() definitions to avoid clang 15 warnings
With clang 15, the following -Werror warnings are produced:

Fix unused variable warning in acpica's nsaccess.c
With clang 15, the following -Werror warning is produced:
sys/contrib/dev/acpica/components/namespace/nsaccess.c:452:29: error: variable 'NumCarats' set but not used [-Werror,-Wunused-but-set-variable]

Here, 'NumCarats' is a variable that is only used when debugging. Since
acpica is contributed code, suppress the warning with a compile flag.
With clang 15, the following -Werror warnings are produced:
sys/dev/mfi/mfi.c:3698:6: error: variable 'timedout' set but not used [-Werror,-Wunused-but-set-variable]

sys/dev/mfi/mfi.c:3742:6: error: variable 'timedout' set but not used [-Werror,-Wunused-but-set-variable]
int timedout = 0;
^
Here, 'timedout' are variables that are only used when debugging,
requiring #if 0 statements to be modified. Mark the variables as
potentially unused, to suppress the warnings.
