Change nlmsvc_lookup_host() to be purpose-built for server-side
nlm_host management. This replaces the generic nlm_lookup_host()
helper function, just like on the client side. The lookup logic is
specialized for server host lookups.
The server side cache also gets its own specialized equivalent of the
nlm_release_host() function.

NFS clients don't need the garbage collection processing that is
performed on nlm_host structures. The client picks up an nlm_host at
mount time and holds a reference to it until the file system is
unmounted.
Servers, on the other hand, don't have a precise way to tell when an
nlm_host is no longer being used, so zero refcount nlm_host entries
are left to expire in the cache after a time.
Basically there's nothing holding a reference to an nlm_host between
individual server-side NLM requests, but we can't afford the expense
of recreating them for every new NLM request from a client. The
nlm_host cache adds some lifetime hysteresis to entries in the cache
so the next time a particular nlm_host is needed, it's likely to be
discovered by a lookup rather than created from whole cloth.
With the new implementation, client nlm_host cache items are no longer
garbage collected, and are destroyed directly by a new release
function specialized for client entries, nlmclnt_release_host(). They
are cached in their own data structure, and have their own lookup
logic, simplified and specialized for client nlm_host entries.
However, the client nlm_host cache still shares reboot recovery logic
with the server nlm_host cache. The NSM "peer rebooted" downcall for
clients and servers still come through the same RPC call. This is a
legacy formal API that would be difficult to alter, and besides, the
user space NSM implementation can't tell the difference between peers
that are clients or servers.
For this reason, the client cache continues to share the
nlm_host_mutex (and reboot recovery logic) with the server cache.

When rpc.statd starts up in user space at boot time, it attempts to
write the latest NSM local state number into
/proc/sys/fs/nfs/nsm_local_state.
If lockd.ko isn't loaded yet (as is the case in most configurations),
that file doesn't exist, thus the kernel's NSM state remains set to
its initial value of zero during lockd operation.
This is a problem because rpc.statd and lockd use the NSM state number
to prevent repeated lock recovery on rebooted hosts. If lockd sends
a zero NSM state, but then a delayed SM_NOTIFY with a real NSM state
number is received, there is no way for lockd or rpc.statd to
distinguish that stale SM_NOTIFY from an actual reboot. Thus lock
recovery could be performed after the rebooted host has already
started reclaiming locks, and those locks will be lost.
We could change /etc/init.d/nfslock so it always modprobes lockd.ko
before starting rpc.statd. However, if lockd.ko is ever unloaded
and reloaded, we are back at square one, since the NSM state is not
preserved across an unload/reload cycle. This may happen frequently
on clients that use automounter. A period of NFS inactivity causes
lockd.ko to be unloaded, and the kernel loses its NSM state setting.
Instead, let's use the fact that rpc.statd plants the local system's
NSM state in every SM_MON (and SM_UNMON) reply. lockd performs a
synchronous SM_MON upcall to the local rpc.statd _before_ sending its
first NLM request to a new remote. This would permit rpc.statd to
provide the current NSM state to lockd, even after lockd.ko had been
unloaded and reloaded.
Note that NLMPROC_LOCK arguments are constructed before the
nsm_monitor() call, so we have to rearrange argument construction very
slightly to make this all work out.
And, the kernel appears to treat NSM state as a u32 (see struct
nlm_args and nsm_res). Make nsm_local_state a u32 as well, to ensure
we don't get bogus comparison results.

Commit b85e4676 added the nlm_privileged_requester() helper to check
whether an RPC request was sent from a local privileged caller. It
recognizes IPv4 privileged callers (from "127.0.0.1"), and IPv6
privileged callers (from "::1").
However, IPV6_ADDR_LOOPBACK is not set for the mapped IPv4 loopback
address (::ffff:7f00:0001), so the test breaks when the kernel's RPC
service is IPv6-enabled but user space is calling via the IPv4
loopback address. This is actually the most common case for IPv6-
enabled RPC services on Linux.
Rewrite the IPv6 check to handle the mapped IPv4 loopback address as
well as a normal IPv6 loopback address.

The NLM XDR decoders for the NLMPROC_SM_NOTIFY procedure should treat

For now, the NLM and NSM implementations should behave exactly as they

The nsm_find() function sets up fresh nsm_handle entries. This is

As much as possible, I would like to keep everything that handles a

source file. That organization should make it pretty simple to see how
all this works.
To me, it makes more sense than the current arrangement to keep
nsm_find() with nsm_monitor() and nsm_unmonitor().

All references to the nlm_host are gone before it is freed. We can
skip making h_nsmhandle NULL just before the nlm_host is deallocated.

The "mon_name" argument of the NSMPROC_MON and NSMPROC_UNMON upcalls
is a string that contains the hostname or IP address of the remote peer
to be notified when this host has rebooted. The sm-notify command uses
this identifier to contact the peer when we reboot, so it must be
either a well-qualified DNS hostname or a presentation format IP
address string.
When the "nsm_use_hostnames" sysctl is set to zero, the kernel's NSM
provides a presentation format IP address in the "mon_name" argument.
Otherwise, the "caller_name" argument from NLM requests is used,
which is usually just the DNS hostname of the peer.
To support IPv6 addresses for the mon_name argument, we use the
nsm_handle's address eye-catcher, which already contains an appropriate
presentation format address string. Using the eye-catcher string
obviates the need to use a large buffer on the stack to form the
presentation address string for the upcall.
This patch also addresses a subtle bug.
An NSMPROC_MON request and the subsequent NSMPROC_UNMON request for the
same peer are required to use the same value for the "mon_name"
argument. Otherwise, rpc.statd's NSMPROC_UNMON processing cannot
locate the database entry for that peer and remove it.
If the setting of nsm_use_hostnames is changed between the time the
kernel sends an NSMPROC_MON request and the time it sends the
NSMPROC_UNMON request for the same peer, the "mon_name" argument for
these two requests may not be the same. This is because the value of
"mon_name" is currently chosen at the moment the call is made based on
the setting of nsm_use_hostnames
To ensure both requests pass identical contents in the "mon_name"
argument, we now select which string to use for the argument in the
nsm_monitor() function. A pointer to this string is saved in the
nsm_handle so it can be used for a subsequent NSMPROC_UNMON upcall.
NB: There are other potential problems, such as how nlm_host_rebooted()
might behave if nsm_use_hostnames were changed while hosts are still
being monitored. This patch does not attempt to address those
problems.

individually enforce it. This creates a slight race condition, since
the enforcement is not coordinated. It's also more complicated than
necessary.
Here instead we have lockd and nfsd each inform common code when they
enter the grace period, and when they're ready to leave the grace
period, and allow normal locking only after both of them are ready to
leave.
We also expect the locks_start_grace()/locks_end_grace() interface here
to be simpler to build on for future cluster/high-availability work,
which may require (for example) putting individual filesystems into
grace, or enforcing grace periods across multiple cluster nodes.
