There are numerous broken references to Documentation files (in other
Documentation files, in comments, etc.). These broken references are
caused by typo's in the references, and by renames or removals of the
Documentation files. Some broken references are simply odd.
Fix these broken references, sometimes by dropping the irrelevant text
they were part of.

We want to remove all OSDs, not just those on the idle LRU.

There were several problems here:
1- we weren't tagging allocations with the pool, so they were never
returned to the pool.
2- msgpool_put didn't add back to the mempool, even it were called.
3- msgpool_release didn't clear the pool pointer, so it would have looped
had #1 not been broken.
These may or may not have been responsible for #1136 or #1381 (BUG due to
non-empty mempool on umount). I can't seem to trigger the crash now using
the method I was using before.

Commit fada4ac339 introduced the usage of kthread API.
kthread_stop is a blocking function which returns only when
the thread exits. In this case, the thread can't exit because it's
waiting for the write lock, which is being held by cmtp_del_connection()
which is waiting for the thread to exit -- deadlock.
Revert cmtp_reset_ctr to its original behavior: non-blocking signalling
for the session to terminate.

Use atomic_t/wake_up_process instead to signal to the thread to exit.

No command should be send before Command Complete event for HCI
reset is received. This fix regression introduced by commit
6bd32326cda(Bluetooth: Use proper timer for hci command timout)
for chips whose reset command takes longer to complete (e.g. CSR)
resulting in next command being send before HCI reset completed.

Removed superfluous event handling which was used to signal
that the rfcomm kthread had been woken. This appears to have been
used to prevent lost wakeups. Correctly ordering when the task
state is set to TASK_INTERRUPTIBLE is sufficient to prevent lost wakeups.
To prevent wakeups which occurred prior to initially setting
TASK_INTERRUPTIBLE from being lost, the main work of the thread loop -
rfcomm_process_sessions() - is performed prior to sleeping.

Dereferencing a user pointer directly from kernel-space without going
through the copy_from_user family of functions is a bad idea. Two of
such usages can be found in the sendmsg code path called from sendmmsg,
added by
commit c71d8ebe7a4496fb7231151cb70a6baa0cb56f9a upstream.
commit 5b47b8038f183b44d2d8ff1c7d11a5c1be706b34 in the 3.0-stable tree.
Usages are performed through memcmp() and memcpy() directly. Fix those
by using the already copied msg_sys structure instead of the __user *msg
structure. Note that msg_sys can be set to NULL by verify_compat_iovec()
or verify_iovec(), which requires additional NULL pointer checks.

Dave Jones reported a lockdep splat triggered by an arp_process() call
from parp_redo().
Commit faa9dcf793be (arp: RCU changes) is the origin of the bug, since
it assumed arp_process() was called under rcu_read_lock(), which is not
true in this particular path.
Instead of adding rcu_read_lock() in parp_redo(), I chose to add it in
neigh_proxy_process() to take care of IPv6 side too.

br_multicast_ipv6_rcv() can call pskb_trim_rcsum() and therefore skb
head can be reallocated.
Cache icmp6_type field instead of dereferencing twice the struct

Checksum of ICMPv6 is not properly computed because the pseudo header is not used.
Thus, the MLD packet gets dropped by the bridge.

This oops have been already fixed with commit
27141666b69f535a4d63d7bc6d9e84ee5032f82a
atm: [br2684] Fix oops due to skb->dev being NULL
It happens that if a packet arrives in a VC between the call to open it on
the hardware and the call to change the backend to br2684, br2684_regvcc
processes the packet and oopses dereferencing skb->dev because it is
NULL before the call to br2684_push().
but have been introduced again with commit
b6211ae7f2e56837c6a4849316396d1535606e90
atm: Use SKB queue and list helpers instead of doing it by-hand.

It's after all necessary to do reset headers here. The reason is we
cannot depend that it gets reseted in __netif_receive_skb once skb is
reinjected. For incoming vlanids without vlan_dev, vlan_do_receive()
returns false with skb != NULL and __netif_reveive_skb continues, skb is
not reinjected.
This might be good material for 3.0-stable as well

sit tunnels (IPv6 tunnel over IPv4) do not implement the "tos inherit"
case to copy the IPv6 transport class byte from the inner packet to
the IPv4 type of service byte in the outer packet. By contrast, ipip
tunnels and GRE tunnels do.
This patch, adapted from the similar code in net/ipv4/ipip.c and
net/ipv4/ip_gre.c, implements that.
This patch applies to 3.0.1, and has been tested on that version.

As rt_iif represents input device even for packets
coming from loopback with output route, it is not an unique
key specific to input routes. Now rt_route_iif has such role,
it was fl.iif in 2.6.38, so better to change the checks at
some places to save CPU cycles and to restore 2.6.38 semantics.
compare_keys:
- input routes: only rt_route_iif matters, rt_iif is same
- output routes: only rt_oif matters, rt_iif is not
used for matching in __ip_route_output_key
- now we are back to 2.6.38 state
ip_route_input_common:
- matching rt_route_iif implies input route
- compared to 2.6.38 we eliminated one rth->fl.oif check
because it was not needed even for 2.6.38
compare_hash_inputs:
Only the change here is not an optimization, it has
effect only for output routes. I assume I'm restoring
the original intention to ignore oif, it was using fl.iif
- now we are back to 2.6.38 state

Using a gcc 4.4.3, warnings are emitted for a possibly uninitialized use
of ecn_ok.
This can happen if cookie_check_timestamp() returns due to not having
seen a timestamp. Defaulting to ecn off seems like a reasonable thing
to do in this case, so initialized ecn_ok to false.

commit 07bd8df5df4369487812bf85a237322ff3569b77
(sch_sfq: fix peek() implementation) changed sfq to use generic
peek helper.
This makes HFSC complain about a non-work-conserving child qdisc, if
prio with sfq child is used within hfsc:
hfsc peeks into prio qdisc, which will then peek into sfq.
returned skb is stashed in sch->gso_skb.
Next, hfsc tries to dequeue from prio, but prio will call sfq dequeue
directly, which may return NULL instead of previously peeked-at skb.
Have prio call qdisc_dequeue_peeked, so sfq->dequeue() is
not called in this case.

This ensures the neighbor entries associated with the bridge
dev are flushed, also invalidating the associated cached L2 headers.
This means we br_add_if/br_del_if ports to implement hand-over and
not wind up with bridge packets going out with stale MAC.
This means we can also change MAC of port device and also not wind
up with bridge packets going out with stale MAC.
This builds on Stephen Hemminger's patch, also handling the br_del_if
case and the port MAC change case.

TCP in some cases uses different global (raw) socket
to send RST and ACK. The transparent flag is not set there.
Currently, it is a problem for rerouting after the previous
change.
Fix it by simplifying the checks in ip_route_me_harder
and use FLOWI_FLAG_ANYSRC even for sockets. It looks safe
because the initial routing allowed this source address to
be used and now we just have to make sure the packet is rerouted.
As a side effect this also allows rerouting for normal
raw sockets that use spoofed source addresses which was not possible
even before we eliminated the ip_route_input call.

compare_keys and ip_route_input_common rely on
rt_oif for distinguishing of input and output routes
with same keys values. But sometimes the input route has
also same hash chain (keyed by iif != 0) with the output
routes (keyed by orig_oif=0). Problem visible if running
with small number of rhash_entries.
Fix them to use rt_route_iif instead. By this way
input route can not be returned to users that request
output route.
The patch fixes the ip_rt_bug errors that were
reported in ip_local_out context, mostly for 255.255.255.255
destinations.
