It is a frequent mistake to confuse the netlink port identifier with a
process identifier. Try to reduce this confusion by renaming fields
that hold port identifiers portid instead of pid.
I have carefully avoided changing the structures exported to
userspace to avoid changing the userspace API.
I have successfully built an allyesconfig kernel with this change.

This change marks interface as down on reset, otherwise the driver can't
reinitialize itself properly.
Without the change a transient problem turns out to be critical and leads
to inavailability to reset the driver without brcmsmac module unload/load
cycle:
ieee80211 phy0: wl0: PSM microcode watchdog fired at 5993 (seconds). Resetting.
brcms_c_dpc : PSM Watchdog, chipid 0xa8d9, chiprev 0x1

ieee80211 phy0: Hardware restart was requested

Pull networking update from David Miller:
"A couple weeks of bug fixing in there. The largest chunk is all the
broken crap Amerigo Wang found in the netpoll layer."
1) netpoll and it's users has several serious bugs:
a) uses GFP_KERNEL with locks held
b) interfaces requiring interrupts disabled are called with them
enabled
c) and vice versa
d) VLAN tag demuxing, as per all other RX packet input paths, is not
applied
All from Amerigo Wang.
2) Hopefully cure the ipv4 mapped ipv6 address TCP early demux bugs for
good, from Neal Cardwell.
3) Unlike AF_UNIX, AF_PACKET sockets don't set a default credentials
when the user doesn't specify one explicitly during sendmsg().
Instead we attach an empty (zero) SCM credential block which is
definitely not what we want. Fix from Eric Dumazet.
4) IPv6 illegally invokes netdevice notifiers with RCU lock held, fix
from Ben Hutchings.
5) inet_csk_route_child_sock() checks wrong inet options pointer, fix
from Christoph Paasch.
6) When AF_PACKET is used for transmit, packet loopback doesn't behave
properly when a socket fanout is enabled, from Eric Leblond.
7) On bluetooth l2cap channel create failure, we leak the socket, from
Jaganath Kanakkassery.
8) Fix all the netprio file handling bugs found by Al Viro, from John
Fastabend.
9) Several error return and NULL deref bug fixes in networking drivers
from Julia Lawall.
10) A large smattering of struct padding et al. kernel memory leaks to
userspace found of Mathias Krause.
11) Conntrack expections in netfilter can access an uninitialized timer,
fix from Pablo Neira Ayuso.
12) Several netfilter SIP tracker bug fixes from Patrick McHardy.
13) IPSEC ipv6 routes are not initialized correctly all the time,
resulting in an OOPS in inet_putpeer(). Also from Patrick McHardy.
14) Bridging does rcu_dereference() outside of RCU protected area, from
Stephen Hemminger.
15) Fix routing cache removal performance regression when looking up
output routes that have a local destination. From Zheng Yan.

iwl_dbgfs_fh_reg_read() can cause crashes and/or
BUG_ON in slub because the ifdefs are wrong, the

This patch reduces the per rate target power eeprom reads for
AR5K_EEPROM_MODE_11A from 10 to 8, as there are only 8 valid
power curve entries on the eeprom. The former 10 reads lead to
equal max power limits per rate and this causes an increasing
distortion for all rates above 24 MBit and leads to a needless
poor performance in 802.11a mode.

Lockdep found an inconsistent lock state when joining a mesh with
ath5k. The problem is that ath5k takes the lock for its beacon state,
ah->block, with spin_lock_irqsave(), while mesh internally takes the
sync_offset_lock with spin_lock_bh() in mesh_sync_offset_adjust_tbtt(),
which in turn is called under ah->block.
This could deadlock if the beacon tasklet was run on the processor
that held the beacon lock during the do_softirq() in spin_unlock_bh().
We probably shouldn't hold the lock around the callbacks, but the
easiest fix is to switch to spin_lock_bh for ah->block: it doesn't
need interrupts disabled anyway as the data in question is only accessed
in softirq or process context.
Fixes the following lockdep warning:

ath_rx_tasklet() calls ath9k_rx_skb_preprocess() and ath9k_rx_skb_postprocess()
in a loop over the received frames. The decrypt_error flag is
initialized to false
just outside ath_rx_tasklet() loop. ath9k_rx_accept(), called by
ath9k_rx_skb_preprocess(),
only sets decrypt_error to true and never to false.
Then ath_rx_tasklet() calls ath9k_rx_skb_postprocess() and passes
decrypt_error to it.
So, after a decryption error, in ath9k_rx_skb_postprocess(), we can
have a leftover value
from another processed frame. In that case, the frame will not be marked with
RX_FLAG_DECRYPTED even if it is decrypted correctly.
When using CCMP encryption this issue can lead to connection stuck
because of CCMP
PN corruption and a waste of CPU time since mac80211 tries to decrypt an already
deciphered frame with ieee80211_aes_ccm_decrypt.
Fix the issue initializing decrypt_error flag at the begging of the
ath_rx_tasklet() loop.

The brcmsmac driver requests firmware but doesn't document the
dependency. This means that software that analyzes the modules to
determine if firmware is needed won't detect it.
Specifically, (at least) openSUSE won't install the kernel-firmware
package if no hardware requires it.
This patch adds the MODULE_FIRMWARE directives.

The current method of assigning the RTS/CTS rate is completely
broken for HT mode and breaks P2P operation. Fix this by using
the basic_rates provided to the driver by mac80211. For now,
choose the lowest supported basic rate for HT frames.
