Eliezer renames several *ll_poll to *busy_poll, but forgets
CONFIG_NET_LL_RX_POLL, so in case of confusion, rename it too.

When CONFIG_NET_LL_RX_POLL is not set, I got:
net/socket.c: In function ‘sock_poll’:
net/socket.c:1165:4: error: implicit declaration of function ‘sk_busy_loop’ [-Werror=implicit-function-declaration]
Fix this by adding a nop when !CONFIG_NET_LL_RX_POLL.

Slaves get the 64B CQE/EQE state from QUERY_HCA, not from the module parameter.
If the parameter is set to zero, the slave outputs an incorrect/irrelevant
warning message that 64B CQEs/EQEs are supported but not enabled (even if the
hypervisor has enabled 64B CQEs/EQEs).

If the user has not assigned a MAC address to a VM, then don't give it MAC which
is based on the PF one. The current derivation scheme is wrong and leads to VM
MAC collisions when the number of cards/hypervisors becomes big enough.
Instead, just give it zeros and let them figure out what to do with that.

There's a race in IPv6 automatic addess assignment. The address is created
with zero lifetime when it's added to various address lists. Before it gets
assigned the correct lifetime, there's a window where a new address may be
configured. This causes the semi-initiated address to be deleted in
addrconf_verify.
This was discovered as a reference leak caused by concurrent run of
__ipv6_ifa_notify for both RTM_NEWADDR and RTM_DELADDR with the same
address.
Fix this by setting the lifetime before the address is added to
inet6_addr_lst.
A few notes:
1. In addrconf_prefix_rcv, by setting update_lft to zero, the
if (update_lft) { ... } condition is no longer executed for newly
created addresses. This is okay, as the ifp fields are set in
ipv6_add_addr now and ipv6_ifa_notify is called (and has been called)
through addrconf_dad_start.
2. The removal of the whole block under ifp->lock in inet6_addr_add is okay,
too, as tstamp is initialized to jiffies in ipv6_add_addr.

As pointed out by Eric Dumazet, net->ipv6.ip6_rt_last_gc should
hold the last time garbage collector was run so that we should
update it whenever fib6_run_gc() calls fib6_clean_all(), not only
if we got there from ip6_dst_gc().

On a high-traffic router with many processors and many IPv6 dst
entries, soft lockup in fib6_run_gc() can occur when number of
entries reaches gc_thresh.
This happens because fib6_run_gc() uses fib6_gc_lock to allow
only one thread to run the garbage collector but ip6_dst_gc()
doesn't update net->ipv6.ip6_rt_last_gc until fib6_run_gc()
returns. On a system with many entries, this can take some time
so that in the meantime, other threads pass the tests in
ip6_dst_gc() (ip6_rt_last_gc is still not updated) and wait for
the lock. They then have to run the garbage collector one after
another which blocks them for quite long.
Resolve this by replacing special value ~0UL of expire parameter
to fib6_run_gc() by explicit "force" parameter to choose between
spin_lock_bh() and spin_trylock_bh() and call fib6_run_gc() with
force=false if gc_thresh is reached but not max_size.

John W. Linville says:
====================
This pull request is intended for the 3.11 stream. It is a bit
larger than usual, as it includes pulls from most of my feeder trees
as well...
For the Bluetooth bits, Gustavo says:
"A few fixes and devices ID additions for 3.11:
* There are 4 new ath3k device ids
* Fixed stack memory usage in ath3k.
* Fixed the init process of BlueFRITZ! devices, they were failing to init
due to an unsupported command we sent.
* Fixed wrong use of PTR_ERR in btusb code that was preventing intel devices
to work properly.
* Fixed race condition between hci_register_dev() and hci_dev_open() that
could cause a NULL pointer dereference.
* Fixed race condition that could call hci_req_cmd_complete() and make some
devices to fail as showed in the log added to the commit message."
Regarding the NFC bits, Samuel says:
"We have:
1) A build failure fix for the NCI SPI transport layer due to a
missing CRC_CCITT Kconfig dependency.
2) A netlink command rename: CMD_FW_UPLOAD was merged during the 3.11
merge window but the typical terminology for loading a firmware to a
target is firmware download rather than upload. In order to avoid any
confusion in a file exported to userspace, we rename this command to
CMD_FW_DOWNLOAD."
Samuel's item #2 isn't strictly a fix, but it seems safe and should
avoid confusion in the future.
As for the mac80211 bits, Johannes says:
"I only have three fixes this time, a fix for a suspend regression, a
patch correcting the initiator in regulatory code and one fix for mesh
station powersave."
With respect to the iwlwifi bits, Johannes says:
"We have a scan fix for passive channels, a new PCI device ID for an old
device, a NIC reset fix, an RF-Kill fix, a fix for powersave when GO
interfaces are present as well as an aggregation session fix (for a
corner case) and a workaround for a firmware design issue - it only
supports a single GTK in D3."
Bringing-up the rear with the Atheros trees, Kalle says:
"Geert Uytterhoeven fixed an ath10k build problem when NO_DMA=y. I added
a missing MAINTAINERS entry for ath10k and updated ath6kl git tree
location."
Along with the above...
Arend van Spriel fixes a brcmfmac WARNING when unplugging the device.
Avinash Patil proves a couple of minor mwifiex fixes relating to P2P mode.
Luciano Coelho updates the MAINTAINERS entry for the wilink drivers.
Stanislaw Gruszka brings an rt2x00 fix for a queue start/stop problem.
Stone Piao fixes another mwifiex problem, a command timeout related to P2P mode.
Tomasz Moń corrects an endian problem in mwifiex.
I'll remind my feeder maintainers to slowdown the patchflow.
Beyond that, please let me know if there are problems!

Loading a firmware into a target is typically called firmware
download, not firmware upload. So we rename the netlink API to
NFC_CMD_FW_DOWNLOAD in order to avoid any terminology confusion from
userspace.

In certain circumstances, such as an HCI driver using __hci_cmd_sync_ev
with HCI_EV_CMD_COMPLETE as the expected completion event there is the
chance that hci_event_packet will call hci_req_cmd_complete twice (once
for the explicitly looked after event and another time in the actual
handler of cmd_complete).
In the case of __hci_cmd_sync_ev this introduces a race where the first
call wakes up the blocking __hci_cmd_sync_ev and lets it complete.
However, by the time that a second __hci_cmd_sync_ev call is already in
progress the second hci_req_cmd_complete call (from the previous
operation) will wake up the blocking function prematurely and cause it
to fail, as witnessed by the following log:

If hci_dev_open() is called after hci_register_dev() added the device to
the hci_dev_list but before the workqueue are created we could run into a
NULL pointer dereference (see below).
This bug is very unlikely to happen, systems using bluetoothd to
manage their bluetooth devices will never see this happen.

PTR_ERR() returns a signed long type value which is limited by IS_ERR(),
it must be a negative number whose range is [-MAX_ERRNO, 0).
The bug here returns negative numbers as error codes, then check it by
"if (ret < 0)", but -PTR_ERR() is actually positive. The wrong use here
leads to failure as below, even panic.

This patch fixes an issue wherein association would fail on P2P
interfaces. This happened because we are checking priv->mode
against NL80211_IFTYPE_STATION. While this check is correct for
infrastructure stations, it would fail P2P clients for which mode
is NL80211_IFTYPE_P2P_CLIENT.
Better check would be bss_role which has only 2 values: STA/AP.

mac80211: cleanup generic suspend/resume procedures
removed check for deleting MONITOR and AP_VLAN when suspend. That can
cause a crash (i.e. in iwlagn_mac_remove_interface()) since we remove
interface in the driver that we did not add before.

This patch is intended to avoid the buffering to non-assoc mesh STA
and also to avoid the triggering of frame to non-assoc mesh STA which
could cause kernel panic in specific hw.
One of the examples, is kernel panic happens to ath9k if user space
inserts the mesh STA and not proceed with the SAE and AMPE, and later
the same mesh STA is detected again. The sta_state of the mesh STA remains
at IEEE80211_STA_NONE and if the ieee80211_sta_ps_deliver_wakeup is called
and subsequently the ath_tx_aggr_wakeup, the kernel panic due to
ath_tx_node_init is not called before to initialize the require data
structures.
This issue is reported by Cedric Voncken before.

Fix this by checking the aggregation state before removing
the hardware queue.

The managed interface PS was not disabled when a GO interface
was added. As a consequence, when the station VMAC was in PS,
the GO also was not on the medium. Fix this.

This allows to clean all kinds of bad state it might be in.
This solves situation where HW RFkill was switched while
the NIC was offline.
Until now, we relied on the firmware to do clean the
interrupt, but new firmwares don't do that any more.

Set SSID bitmap for direct scan even on passive channels,
for the passive-to-active feature. Without this patch only
the SSID from probe request template is sent on passive
channels, after passive-to-active switching, causing us to
not find all desired networks.
Remove the unused passive scan mask constant.

Unfortunately, the firmware only supports replay counters for
a single GTK in D3, so that we should only upload the last
key and use its replay counters. Since mac80211 key iteration
will walk through the keys in order of their addition, simply
use the same HW key index (1) for all GTKs, thus overwriting
previous ones with newer ones. The replay counters for it are
already used.

Since we clear QUEUE_STARTED in rt2x00queue_stop_queue(), following
call to rt2x00queue_pause_queue() reduce to noop, i.e we do not
stop queue in mac80211.
To fix that introduce rt2x00queue_pause_queue_nocheck() function,
which will stop queue in mac80211 directly.
Note that rt2x00_start_queue() explicitly set QUEUE_PAUSED bit.
Note also that reordering operations i.e. first call to
rt2x00queue_pause_queue() and then clear QUEUE_STARTED bit, will race
with rt2x00queue_unpause_queue(), so calling ieee80211_stop_queue()
directly is the only available solution to fix the problem without
major rework.

When the device is physically connected the driver sends a disassoc
command to the device and response triggers the driver to inform cfg80211
about it. However, with the device removed the disassoc command fails.
This patch adds a call to cfg80211_disconnected() when that command fails.
The warning was added by commit below and also cleans up, but better
doing it in the driver if only to get rid of the warning.

If there is no querier on a link then we won't get periodic reports and
therefore won't be able to learn about multicast listeners behind ports,
potentially leading to lost multicast packets, especially for multicast
listeners that joined before the creation of the bridge.
These lost multicast packets can appear since c5c23260594
("bridge: Add multicast_querier toggle and disable queries by default")
in particular.
With this patch we are flooding multicast packets if our querier is
disabled and if we didn't detect any other querier.
A grace period of the Maximum Response Delay of the querier is added to
give multicast responses enough time to arrive and to be learned from
before disabling the flooding behaviour again.

https://bugzilla.redhat.com/show_bug.cgi?id=947250
It showed several backtraces arising for dma_map_* usage without checking the
return code on the mapping. Add the check and abort the rx/tx operation if its
failed. Untested as I have no hardware and the reporter has wandered off, but
seems pretty straightforward.
