sunrpc: fix peername failed on closed listener
nfsd: make sure data is on disk before calling ->fsync
nfsd: fix "insecure" export option
There're some warnings of "nfsd: peername failed (err 107)!"
socket error -107 means Transport endpoint is not connected.
This warning message was outputed by svc_tcp_accept() [net/sunrpc/svcsock.c],
when kernel_getpeername returns -107. This means socket might be CLOSED.
And svc_tcp_accept was called by svc_recv() [net/sunrpc/svc_xprt.c]
if (test_bit(XPT_LISTENER, &xprt->xpt_flags)) {
<snip>
newxpt = xprt->xpt_ops->xpo_accept(xprt);
<snip>
So this might happen when xprt->xpt_flags has both XPT_LISTENER and XPT_CLOSE.
Let's take a look at commit b0401d72, this commit has moved the close
processing after do recvfrom method, but this commit also introduces this
warnings, if the xpt_flags has both XPT_LISTENER and XPT_CLOSED, we should
close it, not accpet then close.

mac80211 does not propagate failed hardware reconfiguration
requests. For suspend and resume this is important due to all
the possible issues that can come out of the suspend <-> resume
cycle. Not propagating the error means cfg80211 will assume
the resume for the device went through fine and mac80211 will
continue on trying to poke at the hardware, enable timers,
queue work, and so on for a device which is completley
unfunctional.
The least we can do is to propagate device start issues and
warn when this occurs upon resume. A side effect of this patch
is we also now propagate the start errors upon harware
reconfigurations (non-suspend), but this should also be desirable
anyway, there is not point in continuing to reconfigure a
device if mac80211 was unable to start the device.

When mac80211 suspends it calls a driver's suspend callback
as a last step and after that the driver assumes no calls will
be made to it until we resume and its start callback is kicked.
If such calls are made, however, suspend can end up throwing
hardware in an unexpected state and making the device unusable
upon resume.
Fix this by preventing mac80211 to schedule dynamic_ps_disable_work
by checking for when mac80211 starts to suspend and starts
quiescing. Frames should be allowed to go through though as
that is part of the quiescing steps and we do not flush the
mac80211 workqueue since it was already done towards the
beginning of suspend cycle.
The other mac80211 issue will be hanled in the next patch.

It is not clear to me how the first "direct probe" here
happens, but this seems to be a race condition, if the
user requests to deauth after requesting assoc, but before
the assoc response is received. In that case, it may
happen that mac80211 tries to report the assoc success to
cfg80211, but gets blocked on the wdev lock that is held
because the user is requesting the deauth.
The result is that we run into a warning. This is mostly
harmless, but maybe cause an unexpected event to be sent
to userspace; we'd send an assoc success event although
userspace was no longer expecting that.
To fix this, remove the warning and check whether the
race happened and in that case abort processing.

When fixed bssid is requested when joining an ibss network, incoming
beacons that match the configured bssid cause mac80211 to create new
sta entries, even before the ibss interface is in joined state.
When that happens, it fails to bring up the interface entirely, because
it checks for existing sta entries before joining.
This patch fixes this bug by refusing to create sta info entries before
the interface is fully operational.

One such a case is transparent proxying where we pretend to be

be used on outbound.

This is a new generic kernel FIFO implementation.
The current kernel fifo API is not very widely used, because it has to
many constrains. Only 17 files in the current 2.6.31-rc5 used it.
FIFO's are like list's a very basic thing and a kfifo API which handles
the most use case would save a lot of development time and memory
resources.
I think this are the reasons why kfifo is not in use:
- The API is to simple, important functions are missing
- A fifo can be only allocated dynamically
- There is a requirement of a spinlock whether you need it or not
- There is no support for data records inside a fifo
So I decided to extend the kfifo in a more generic way without blowing up
the API to much. The new API has the following benefits:
- Generic usage: For kernel internal use and/or device driver.
- Provide an API for the most use case.
- Slim API: The whole API provides 25 functions.
- Linux style habit.
- DECLARE_KFIFO, DEFINE_KFIFO and INIT_KFIFO Macros
- Direct copy_to_user from the fifo and copy_from_user into the fifo.
- The kfifo itself is an in place member of the using data structure, this save an
indirection access and does not waste the kernel allocator.
- Lockless access: if only one reader and one writer is active on the fifo,
which is the common use case, no additional locking is necessary.
- Remove spinlock - give the user the freedom of choice what kind of locking to use if
one is required.
- Ability to handle records. Three type of records are supported:
- Variable length records between 0-255 bytes, with a record size
field of 1 bytes.
- Variable length records between 0-65535 bytes, with a record size
field of 2 bytes.
- Fixed size records, which no record size field.
- Preserve memory resource.
- Performance!
- Easy to use!
This patch:
Since most users want to have the kfifo as part of another object,
reorganize the code to allow including struct kfifo in another data
structure. This requires changing the kfifo_alloc and kfifo_init
prototypes so that we pass an existing kfifo pointer into them. This
patch changes the implementation and all existing users.

mac80211: rework MLME for multiple authentications
inadvertedly broke WMM because it removed, along with
a bunch of other now useless initialisations, the line
initialising sdata->u.mgd.wmm_last_param_set to -1
which would make it adopt any WMM parameter set. If,
as is usually the case, the AP uses WMM parameter set
sequence number zero, we'd never update it until the
AP changes the sequence number.
Add the missing initialisation back to get the WMM
settings from the AP applied locally.

I noticed yesterday, because Jeff had noticed
a speed regression, cf. bug
http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2138
that the SM PS settings for peers were wrong.
Instead of overwriting the SM PS settings with
the local bits, we need to keep the remote bits.
The bug was part of the original HT code from
over two years ago, but unfortunately nobody
noticed that it makes no sense -- we shouldn't
be overwriting the peer's setting with our own
but rather keep it intact when masking the peer
capabilities with our own.
While fixing that, I noticed that the masking of
capabilities is completely useless for most of
the bits, so also fix those other bits.
Finally, I also noticed that PSMP_SUPPORT no
longer exists in the final 802.11n version, so
also remove that.

When handling the gssd downcall, the kernel should distinguish between a
successful downcall that contains an error code and a failed downcall
(i.e. where the parsing failed or some other sort of problem occurred).
In the former case, gss_pipe_downcall should be returning the number of
bytes written to the pipe instead of an error. In the event of other
errors, we generally want the initiating task to retry the upcall so
we set msg.errno to -EAGAIN. An unexpected error code here is a bug
however, so BUG() in that case.

Also, it does not get put into the dcache hash if DCACHE_UNHASHED is clear;

This is likely caused by the change in the 'estab' parameter
passed to tcp_parse_options() when invoked by the functions
in net/ipv4/tcp_minisocks.c
But even if that is fixed, the ->conn_request() changes made in
this patch series is fundamentally wrong. They try to use the
listening socket's 'dst' to probe the route settings. The
listening socket doesn't even have a route, and you can't
get the right route (the child request one) until much later
after we setup all of the state, and it must be done by hand.
This stuff really isn't ready, so the best thing to do is a
full revert. This reverts the following commits:

Makes use of skip_spaces() defined in lib/string.c for removing leading
spaces from strings all over the tree.
It decreases lib.a code size by 47 bytes and reuses the function tree-wide:
text data bss dec hex filename
64688 584 592 65864 10148 (TOTALS-BEFORE)
64641 584 592 65817 10119 (TOTALS-AFTER)
Also, while at it, if we see (*str && isspace(*str)), we can be sure to
remove the first condition (*str) as the second one (isspace(*str)) also
evaluates to 0 whenever *str == 0, making it redundant. In other words,
"a char equals zero is never a space".
Julia Lawall tried the semantic patch (http://coccinelle.lip6.fr) below,
and found occurrences of this pattern on 3 more files:
