After commit 3262c816a3d7fb1eaabce633caa317887ed549ae "[PATCH] knfsd:
split svc_serv into pools", svc_delete_xprt (then svc_delete_socket) no
longer removed its xpt_ready (then sk_ready) field from whatever list it
was on, noting that there was no point since the whole list was about to
be destroyed anyway.
That was mostly true, but forgot that a few svc_xprt_enqueue()'s might
still be hanging around playing with the about-to-be-destroyed list, and
could get themselves into trouble writing to freed memory if we left
this xprt on the list after freeing it.
(This is actually functionally identical to a patch made first by Ben
Greear, but with more comments.)

As promised in feature-removal-schedule.txt it is time to
remove the nfsctl system call.
Userspace has perferred to not use this call throughout 2.6 and it has been
excluded in the default configuration since 2.6.36 (9 months ago).
So this patch removes all the code that was being compiled out.
There are still references to sys_nfsctl in various arch systemcall tables
and related code. These should be cleaned out too, probably in the next
merge window.

DESTROY_CLIENTID MAY be preceded with a SEQUENCE operation as long as
the client ID derived from the session ID of SEQUENCE is not the same
as the client ID to be destroyed. If the client IDs are the same,
then the server MUST return NFS4ERR_CLIENTID_BUSY.
(that's not implemented yet)
If DESTROY_CLIENTID is not prefixed by SEQUENCE, it MUST be the only
operation in the COMPOUND request (otherwise, the server MUST return
NFS4ERR_NOT_ONLY_OP).
This fixes the error return; before, we returned
NFS4ERR_OP_NOT_IN_SESSION; after this patch, we return NFS4ERR_NOTSUPP.

On reading the ext_csd for the first time (in 1 bit mode), save the
ext_csd information needed for bus width compare.
On every pass we make re-reading the ext_csd, compare the data
against the saved ext_csd data.
This fixes a regression introduced in 3.0-rc1 by 08ee80cc397ac1a3
("mmc: core: eMMC bus width may not work on all platforms"), which
incorrectly assumed we would be re-reading the ext_csd at resume-
time.

Because struct rpcbind_args *map was declared static, if two
threads entered this method at the same time, the values
assigned to map could be sent two two differen tasks.
This could cause all sorts of problems, include use-after-free
and double-free of memory.
Fix this by removing the static declaration so that the map
pointer is on the stack.

In current pnfs tree, all the layouts set mds_offset in their
.write_pagelist member.
mds_offset is only used by generic layer and should be handled by it.
This patch is for upstream. It is needed in this -rc series to fix a
bug in objects layout_commit.
I'll send patches for objects and blocks to be
squashed into current pnfs tree.

closing socket
Trigger user ABORT if application closes a socket which has data
queued on the socket receive queue or chunks waiting on the
reassembly or ordering queue as this would imply data being lost
which defeats the point of a graceful shutdown.
This behavior is already practiced in TCP.
We do not check the input queue because that would mean to parse
all chunks on it to look for unacknowledged data which seems too
much of an effort. Control chunks or duplicated chunks may also
be in the input queue and should not be stopping a graceful
shutdown.

Unlike CCMP, the presence or absence of the QoS
field doesn't change the encryption, only the
TID is used. When no QoS field is present, zero
is used as the TID value. This means that it is
possible for an attacker to take a QoS packet
with TID 0 and replay it as a non-QoS packet.
Unfortunately, mac80211 uses different IVs for
checking the validity of the packet's TKIP IV
when it checks TID 0 and when it checks non-QoS
packets. This means it is vulnerable to this
replay attack.
To fix this, use the same replay counter for
TID 0 and non-QoS packets by overriding the
rx->queue value to 0 if it is 16 (non-QoS).
This is a minimal fix for now. I caused this
issue in

While sending aggregated frames in AES, the AR5416 chips
required additional padding b/w subframes. This workaround
is not needed for edma (AR9003 family) chips. With this patch
~4Mbps thoughput improvement was observed in clear environment.

There was a deadlock when rfkill-blocking a wireless interface,
because we were locking the rdev mutex on NETDEV_GOING_DOWN to stop
sched_scans that were eventually running. The rfkill block code was
already holding a mutex under rdev:

To fix this, add a new mutex specifically for sched_scan, to protect

PTS test A2DP/SRC/SRC_SET/TC_SRC_SET_BV_02_I revealed that
( probably after the df3c3931e commit ) the l2cap connection
could not be established in case when the "Auth Complete" HCI
event does not arive before the initiator send "Configuration
request", in which case l2cap replies with "Command rejected"
since the channel is still in BT_CONNECT2 state.

Partial revert of commit aabf6f89. When the hidp session thread
was converted from kernel_thread to kthread, the atomic/wakeups
were replaced with kthread_stop. kthread_stop has blocking semantics
which are inappropriate for the hidp session kthread. In addition,
the kthread signals itself to terminate in hidp_process_hid_control()
- it cannot do this with kthread_stop().
Lastly, a wakeup can be lost if the wakeup happens between checking
for the loop exit condition and setting the current state to
TASK_INTERRUPTIBLE. (Without appropriate synchronization mechanisms,
the task state should not be changed between the condition test and
the yield - via schedule() - as this creates a race between the
wakeup and resetting the state back to interruptible.)

A remote user can provide a small value for the command size field in
the command header of an l2cap configuration request, resulting in an
integer underflow when subtracting the size of the configuration request
header. This results in copying a very large amount of data via
memcpy() and destroying the kernel heap. Check for underflow.

Upon "ip xfrm state update ..", xfrm_add_sa() takes an extra reference on
the user-supplied SA and forgets to drop the reference when
xfrm_state_update() returns 0. This leads to a memory leak as the
parameter SA is never freed. This change attempts to fix the leak by
calling __xfrm_state_put() when xfrm_state_update() updates a valid SA
(err = 0). The parameter SA is added to the gc list when the final
reference is dropped by xfrm_add_sa() upon completion.

When initiating a graceful shutdown while having data chunks
on the retransmission queue with a peer which is in zero
window mode the shutdown is never completed because the
retransmission error count is reset periodically by the
following two rules:
- Do not timeout association while doing zero window probe.
- Reset overall error count when a heartbeat request has
been acknowledged.
The graceful shutdown will wait for all outstanding TSN to
be acknowledged before sending the SHUTDOWN request. This
never happens due to the peer's zero window not acknowledging
the continuously retransmitted data chunks. Although the
error counter is incremented for each failed retransmission,
the receiving of the SACK announcing the zero window clears
the error count again immediately. Also heartbeat requests
continue to be sent periodically. The peer acknowledges these
requests causing the error counter to be reset as well.
This patch changes behaviour to only reset the overall error
counter for the above rules while not in shutdown. After
reaching the maximum number of retransmission attempts, the
T5 shutdown guard timer is scheduled to give the receiver
some additional time to recover. The timer is stopped as soon
as the receiver acknowledges any data.
The issue can be easily reproduced by establishing a sctp
association over the loopback device, constantly queueing
data at the sender while not reading any at the receiver.
Wait for the window to reach zero, then initiate a shutdown
by killing both processes simultaneously. The association
will never be freed and the chunks on the retransmission
queue will be retransmitted indefinitely.
