As of f025adf191924e3a75ce80e130afcd2485b53bb8 "sunrpc: Properly decode
kuids and kgids in RPC_AUTH_UNIX credentials" any rpc containing a -1
(0xffff) uid or gid would fail with a badcred error.
Commit afe3c3fd5392b2f0066930abc5dbd3f4b14a0f13 "svcrpc: fix failures to
handle -1 uid's and gid's" fixed part of the problem, but overlooked the
gid upcall--the kernel can request supplementary gid's for the -1 uid,
but mountd's attempt write a response will get -EINVAL.
Symptoms were nfsd failing to reply to the first attempt to use a newly
negotiated krb5 context.

When a cache entry is replaced, the "expiry_time" get set to
zero by a call to "cache_fresh_locked(..., 0)" at the end of
"sunrpc_cache_update".
This low expiry time makes cache_check() think that the 'refresh_age'
is negative, so the 'age' is comparatively large and a refresh is
triggered.
However refreshing a replaced entry it pointless, it cannot achieve
anything useful.
So teach cache_check to ignore a low refresh_age when expiry_time
is zero.

commit d202cce8963d9268ff355a386e20243e8332b308
sunrpc: never return expired entries in sunrpc_cache_lookup
moved the 'entry is expired' test from cache_check to
sunrpc_cache_lookup, so that it happened early and some races could
safely be ignored.
However the ip_map (in svcauth_unix.c) has a separate single-item
cache which allows quick lookup without locking. An entry in this
case would not be subject to the expiry test and so could be used
well after it has expired.
This is not normally a big problem because the first time it is used
after it is expired an up-call will be scheduled to refresh the entry
(if it hasn't been scheduled already) and the old entry will then
be invalidated. So on the second attempt to use it after it has
expired, ip_map_cached_get will discard it.
However that is subtle and not ideal, so replace the "!cache_valid"
test with "cache_is_expired".
In doing this we drop the test on the "CACHE_VALID" bit. This is
unnecessary as the bit is never cleared, and an entry will only
be cached if the bit is set.

It is possible for a race to set CACHE_PENDING after cache_clean()
has removed a cache entry from the cache.
If CACHE_PENDING is still set when the entry is finally 'put',
the cache_dequeue() will never happen and we can leak memory.
So set a new flag 'CACHE_CLEANED' when we remove something from
the cache, and don't queue any upcall if it is set.
If CACHE_PENDING is set before CACHE_CLEANED, the call that
cache_clean() makes to cache_fresh_unlocked() will free memory
as needed. If CACHE_PENDING is set after CACHE_CLEANED, the
test in sunrpc_cache_pipe_upcall will ensure that the memory
is not allocated.

cache_fresh_unlocked() is called when a cache entry
has been updated and ensures that if there were any
pending upcalls, they are cleared.
So every time we update a cache entry, we should call this,
and this should be the only way that we try to clear
pending calls (that sort of uniformity makes code sooo much
easier to read).
try_to_negate_entry() will (possibly) mark an entry as
negative. If it doesn't, it is because the entry already
is VALID.
So the entry will be valid on exit, so it is appropriate to
call cache_fresh_unlocked().
So tidy up try_to_negate_entry() to do that, and remove
partial open-coded cache_fresh_unlocked() from the one
call-site of try_to_negate_entry().
In the other branch of the 'switch(cache_make_upcall())',
we again have a partial open-coded version of cache_fresh_unlocked().
Replace that with a real call.
And again in cache_clean(), use a real call to cache_fresh_unlocked().
These call sites might previously have called
cache_revisit_request() if CACHE_PENDING wasn't set.
This is never necessary because cache_revisit_request() can
only do anything if the item is in the cache_defer_hash,
However any time that an item is added to the cache_defer_hash
(setup_deferral), the code immediately tests CACHE_PENDING,
and removes the entry again if it is clear. So all other
places we only need to 'cache_revisit_request' if we've
just cleared CACHE_PENDING.

We currently queue an upcall after setting CACHE_PENDING,
and dequeue after clearing CACHE_PENDING.
So a request should only be present when CACHE_PENDING is set.
However we don't combine the test and the enqueue/dequeue in
a protected region, so it is possible (if unlikely) for a race
to result in a request being queued without CACHE_PENDING set,
or a request to be absent despite CACHE_PENDING.
So: include a test for CACHE_PENDING inside the regions of
enqueue and dequeue where queue_lock is held, and abort
the operation if the value is not as expected.
Also remove the early 'return' from cache_dequeue() to ensure that it
always removes all entries: As there is no locking between setting
CACHE_PENDING and calling sunrpc_cache_pipe_upcall it is not
inconceivable for some other thread to clear CACHE_PENDING and then
someone else to set it and call sunrpc_cache_pipe_upcall, both before
the original threads completed the call.
With this, it perfectly safe and correct to:
- call cache_dequeue() if and only if we have just
cleared CACHE_PENDING
- call sunrpc_cache_pipe_upcall() (via cache_make_upcall)
if and only if we have just set CACHE_PENDING.

This case shouldn't happen--the administrator shouldn't really allow
other applications access to the export until clients have had the
chance to reclaim their state--but if it does then we should set the
"return this lease immediately" bit on the reply. That still leaves
some small races, but it's the best the protocol allows us to do in the
case a lease is ripped out from under us....

This reverts commit eb2099f31b0f090684a64ef8df44a30ff7c45fc2 "nfsd4:
release lockowners on last unlock in 4.1 case". Trond identified
language in rfc 5661 section 8.2.4 which forbids this behavior:
Stateids associated with byte-range locks are an exception.
They remain valid even if a LOCKU frees all remaining locks, so
long as the open file with which they are associated remains
open, unless the client frees the stateids via the FREE_STATEID
operation.
And bakeathon 2013 testing found a 4.1 freebsd client was getting an
incorrect BAD_STATEID return from a FREE_STATEID in the above situation
and then failing.
The spec language honestly was probably a mistake but at this point with
implementations already following it we're probably stuck with that.

We saw a v4.0 client's create fail as follows:
- open create succeeds and gets a read delegation
- client attempts to set mode on new file, gets DELAY while
server recalls delegation.
- client attempts a CLAIM_DELEGATE_CUR open using the
delegation, gets error because of new file mode.
This probably can't happen on a recent kernel since we're no longer
giving out delegations on create opens. Nevertheless, it's a
bug--reclaim opens should bypass permission checks.

Though clients we care about mostly don't do this, it is possible for
rpc requests to be sent in multiple fragments. Here we have a sanity
check to ensure that the final received rpc isn't too small--except that
the number we're actually checking is the length of just the final
fragment, not of the whole rpc. So a perfectly legal rpc that's
unluckily fragmented could cause the server to close the connection
here.

If we detect that an rpc is too short, we abort and close the
connection. Except, there's a bug here: we're leaving sk_datalen
nonzero without leaving any pages in the sk_pages array. The most
likely result of the inconsistency is a subsequent crash in
svc_tcp_clear_pages.
Also demote the BUG_ON in svc_tcp_clear_pages to a WARN.

A freebsd NFSv4.0 client was getting rare IO errors expanding a tarball.
A network trace showed the server returning BAD_XDR on the final getattr
of a getattr+write+getattr compound. The final getattr started on a
page boundary.
I believe the Linux client ignores errors on the post-write getattr, and
that that's why we haven't seen this before.

The nfs4_open_delegation logic is unecessarily baroque.
Also stop pretending we support write delegations in several places.

When an exclusive create is done with the mode bits
set (aka open(testfile, O_CREAT | O_EXCL, 0777)) this
causes a OPEN op followed by a SETATTR op. When a
read delegation is given in the OPEN, it causes
the SETATTR to delay with EAGAIN until the
delegation is recalled.
This patch caused exclusive creates to give out
a write delegation (which turn into no delegation)
which allows the SETATTR seamlessly succeed.

We don't support gss on the backchannel. We should state that fact up
front rather than just letting things continue and later making the
client try to figure out why the backchannel isn't working.
Trond suggested instead returning NFS4ERR_NOENT. I think it would be
tricky for the client to distinguish between the case "I don't support
gss on the backchannel" and "I can't find that in my cache, please
create another context and try that instead", and I'd prefer something
that currently doesn't have any other meaning for this operation, hence
the (somewhat arbitrary) NFS4ERR_ENCR_ALG_UNSUPP.

Somebody noticed LTP was complaining about O_NONBLOCK opens of
/proc/net/rpc/use-gss-proxy succeeding and then a following read
hanging.
I'm not convinced LTP really has any business opening random proc files
and expecting them to behave a certain way. Maybe this isn't really a
bug.
But in any case the O_NONBLOCK behavior could be useful for someone that
wants to test whether gss-proxy is up without waiting.

We shouldn't be returning success from this function without also
filling in the return values ctx and ctxlen.
Note currently this doesn't appear to cause bugs since the only
inode_getsecctx caller I can find is fs/sysfs/inode.c, which only calls
this if security_inode_setsecurity succeeds. Assuming
security_inode_setsecurity is set to cap_inode_setsecurity whenever
inode_getsecctx is set to cap_inode_getsecctx, this function can never
actually called.
So I noticed this only because the server labeled NFS patches add a real
caller.

This code assumes that any client using exchange_id is using NFSv4.1,
but with the introduction of 4.2 that will no longer true.
This main effect of this is that client callbacks will use the same
minorversion as that used on the exchange_id.
Note that clients are forbidden from mixing 4.1 and 4.2 compounds. (See
rfc 5661, section 2.7, #13: "A client MUST NOT attempt to use a stateid,
filehandle, or similar returned object from the COMPOUND procedure with
minor version X for another COMPOUND procedure with minor version Y,
where X != Y.") However, we do not currently attempt to enforce this
except in the case of mixing zero minor version with non-zero minor
versions.

Pull misc fixes from David Woodhouse:
"This is some miscellaneous cleanups that don't really belong anywhere
else (or were ignored), that have been sitting in linux-next for some
time. Two of them are fixes resulting from my audit of krealloc()
usage that don't seem to have elicited any response when I posted
them, and the other three are patches from Artem removing dead code."
* tag 'for-linus-20130509' of git://git.infradead.org/~dwmw2/random-2.6:
pcmcia: remove RPX board stuff
m68k: remove rpxlite stuff
pcmcia: remove Motorola MBX860 support
params: Fix potential memory leak in add_sysfs_param()
dell-laptop: Fix krealloc() misuse in parse_da_table()
