This happened on a machine with a custom hotplug script calling nameif,
probably due to slow firmware loading. At the time nameif uses ethtool
to gather interface information, i2400m->fw_name is zero and so a null
pointer dereference occurs from within i2400m_get_drvinfo().

In https://bugzilla.redhat.com/show_bug.cgi?id=770207, slowdowns of driver
rtl8192ce are reported. One fix (commit a9b89e2) has already been applied,
and it helped, but the maximum RX speed would still drop to 1 Mbps. As in
the previous fix, the initial gain was determined to be the problem; however,
the problem arises from a setting of the gain when scans are started.
Driver rtl8192de also has the same code structure - this one is fixed as well.

Another good catch from Jakub Kicinski. This patch fixes my
recent commit: ed61e2b02027935520d1be884fac0b2ffce8379a
"rt2x00: rt2800usb: rework txdone code"
We should reread status register only when nobody else start already
reading status i.e. test_and_set_bit(TX_STATUS_READING, flags) return 0.

This is fix for my current commit
ed61e2b02027935520d1be884fac0b2ffce8379a
"rt2x00: rt2800usb: rework txdone code"
We should schedule txdone work on timeout, otherwise if newer get
tx status from hardware, we will never report tx status to mac80211
and eventually never wakeup tx queue.

commit 0d95521ea7 (ath9k: use split rx buffers to get rid of order-1 skb
allocations) added in memory leak in error path.
sc->rx.frag should be cleared after the pskb_expand_head() call, or else
we jump to requeue_drop_frag and leak an skb.

When we have downlink traffic alone and the station is going thru
bgscan, the client is out of operating channel for around 1000ms which
is too long. The mac80211 decides when to switch back to oper channel
based on tx queue, bad latency and listen time. As the station does not
have tx traffic, the bgscan can easily affect downlink throughput. By
reducing the listen time, it helps the associated AP to retain the
downstream rate.

Current commit 0775f9f90cdaf40fbf69b3192b3dddb2b3436f45
"mac80211: remove spurious BSSID change flag" exposed bug on iwlegacy,
that we do not set BSSID address correctly and then device was not able
to receive frames after successful associate.
On the way fix scan canceling comment. Apparently ->post_associate()
do cancel scan itself, but scan cancel on BSS_CHANGED_BSSID is needed.
I'm not sure why, but when I removed it, I had frequent auth failures:
wlan4: send auth to 54:e6:fc:98:63:fe (try 1/3)
wlan4: send auth to 54:e6:fc:98:63:fe (try 2/3)
wlan4: send auth to 54:e6:fc:98:63:fe (try 3/3)
wlan4: authentication with 54:e6:fc:98:63:fe timed out

Currently the maximum noise floor limit is set as too high (-60dB). The
assumption of having a higher threshold limit is that it would help
de-sensitize the receiver (reduce phy errors) from continuous
interference. But when we have a bursty interference where there are
collisions and then free air time and if the receiver is desensitized too
much, it will miss the normal packets too. Lets make use of chips
specific min, nom and max limits always. This patch helps to improve the
connection stability in congested networks.

This il->vif is dereferenced in different part of iwlegacy code, so do
not nullify it. This should fix random crashes observed in companion
with microcode errors i.e. crash in il3945_config_ap().
Additionally this should address also
WARNING: at drivers/net/wireless/iwlegacy/common.c:4656 il_mac_remove_interface
at least one of the possible reasons of that warning.

skb_add_rx_frag() API is misleading.

Pull "ARM: driver specific updates" from Arnd Bergmann:
"These are all specific to some driver. They are typically the
platform side of a change in the drivers directory, such as adding a
new driver or extending the interface to the platform. In cases where
there is no maintainer for the driver, or the maintainer prefers to
have the platform changes in the same branch as the driver changes,
the patches to the drivers are included as well.
A much smaller set of driver updates that depend on other branches
getting merged first will be sent later.

fuse.c. In rtc-sa1100.c, the global removal of IRQF_DISABLED

The CS89x0 ethernet controller is used on a number of evaluation
boards, such as the MX31ADS. The current driver has memory address and
IRQ settings for each board on which this controller is used. Driver
updates are therefore required to support other boards that also use
the CS89x0. To avoid these driver updates, a better mechanism
(platform driver support) is added to communicate the board dependent
settings to the driver.

When xen_emul_unplug=never is specified on kernel command line
reading files from /sys/hypervisor is broken (returns -EBUSY).
It is caused by xen_bus dependency on platform-pci and
platform-pci isn't initialized when xen_emul_unplug=never is
specified.
Fix it by allowing platform-pci to ignore xen_emul_unplug=never,
and do not intialize xen_[blk|net]front instead.

Pull networking fixes from David Miller:
1) L2TP doesn't get autoloaded when you try to open an L2TP socket due
to a missing module alias, fix from Benjamin LaHaise.
2) Netlabel and RDS should propagate gfp flags given to them by
callers, fixes from Dan Carpeneter.
3) Recursive locking fix in usbnet wasn't bulletproof and can result in
objects going away mid-flight due to races, fix from Ming Lei.
4) Fix up some confusion about a bool module parameter in netfilter's
iptable_filter and ip6table_filter, from Rusty Russell.
5) If SKB recycling is used via napi_reuse_skb() we end up with
different amounts of headroom reserved than we had at the original
SKB allocation. Fix from Eric Dumazet.
6) Fix races in TG3 driver ring refilling, from Michael Chan.
7) We have callbacks for IPSEC replay notifiers, but some call sites
were not using the ops method and instead were calling one of the
implementations directly. Oops. Fix from Steffen Klassert.
8) Fix IP address validation properly in the bonding driver, the
previous fix only works with netlink where the subnet mask and IP
address are changed in one atomic operation. When 'ifconfig' ioctls
are used the IP address and the subnet mask are changed in two
distinct operations. Fix from Andy Gospodarek.
9) Provide a sky2 module operation to work around power management
issues with some BIOSes. From Stephen Hemminger.

usbnet should centrally handle busy reporting in the rx path
so subdrivers need not worry. This hurts use cases which do
rx only or predominantly.

The following patch aimed to resolve an issue where secondary, tertiary,
etc. addresses added to bond interfaces could overwrite the
bond->master_ip and vlan_ip values.
commit 917fbdb32f37e9a93b00bb12ee83532982982df3
Author: Henrik Saavedra Persson <henrik.e.persson@ericsson.com>
Date: Wed Nov 23 23:37:15 2011 +0000
bonding: only use primary address for ARP
That patch was good because it prevented bonds using ARP monitoring from
sending frames with an invalid source IP address. Unfortunately, it
didn't always work as expected.
When using an ioctl (like ifconfig does) to set the IP address and
netmask, 2 separate ioctls are actually called to set the IP and netmask
if the mask chosen doesn't match the standard mask for that class of
address. The first ioctl did not have a mask that matched the one in
the primary address and would still cause the device address to be
overwritten. The second ioctl that was called to set the mask would
then detect as secondary and ignored, but the damage was already done.
This was not an issue when using an application that used netlink
sockets as the setting of IP and netmask came down at once. The
inconsistent behavior between those two interfaces was something that
needed to be resolved.
While I was thinking about how I wanted to resolve this, Ralf Zeidler
came with a patch that resolved this on a RHEL kernel by keeping a full
shadow of the entries in dev->ifa_list for the bonding device and vlan
devices in the bonding driver. I didn't like the duplication of the
list as I want to see the 'bonding' struct and code shrink rather than
grow, but liked the general idea.
As the Subject indicates this patch drops the master_ip and vlan_ip
elements from the 'bonding' and 'vlan_entry' structs, respectively.
This can be done because a device's address-list is now traversed to
determine the optimal source IP address for ARP requests and for checks
to see if the bonding device has a particular IP address. This code
could have all be contained inside the bonding driver, but it made more
sense to me to EXPORT and call inet_confirm_addr since it did exactly
what was needed.
I tested this and a backported patch and everything works as expected.
Ralf also helped with verification of the backported patch.
Thanks to Ralf for all his help on this.

URB unlinking is always racing with its completion and tx_complete
may be called before or during running usb_unlink_urb, so tx_complete
must not clear urb->dev since it will be used in unlink path,
otherwise invalid memory accesses or usb device leak may be caused
inside usb_unlink_urb.

Commit 4231d47e6fe69f061f96c98c30eaf9fb4c14b96d(net/usbnet: avoid
recursive locking in usbnet_stop()) fixes the recursive locking
problem by releasing the skb queue lock, but it makes usb_unlink_urb
racing with defer_bh, and the URB to being unlinked may be freed before
or during calling usb_unlink_urb, so use-after-free problem may be
triggerd inside usb_unlink_urb.
The patch fixes the use-after-free problem by increasing URB
reference count with skb queue lock held before calling
usb_unlink_urb, so the URB won't be freed until return from
usb_unlink_urb.

The recently added parity error handling used an error code that was
already defined for a different error. This could lead to bnx2x
firmware assert. We need to fix this with new error codes that are
defined for parity error only.

The RSS feature in tg3 hardware has only one rx producer ring for all
RSS rings. NAPI vector 1 is special and handles the refilling of the
rx producer ring on behalf of all RSS rings. There is a race condition
between these RSS NAPIs and the NAPI[1]. If NAPI[1] finishes checking
for refill and then another RSS ring empties the rx producer ring
before NAPI[1] exits NAPI, the chip will be completely out of SKBs in
the rx producer ring.
We fix this by adding a flag tp->rx_refill and rely on napi_schedule()/
napi_complete() to help synchronize it to close the race condition.
Update driver version to 3.123.

The current driver defaults to 1M MTT segments, where each segment holds
8 MTT entries. This limits the total memory registered to 8M * PAGE_SIZE
which is 32GB with 4K pages. Since systems that have much more memory
are pretty common now (at least among systems with InfiniBand hardware),
this limit ends up getting hit in practice quite a bit.
Handle this by having the driver allocate at least enough MTT entries to
cover 2 * totalram pages.

Set the MTU for IB ports in the driver instead of using the firmware
default of 2KB (the driver defaults to 4KB). Allow for dynamic mtu
configuration through a new, per-port sysfs entry.
Since there's a dependency between the port MTU and the max number of
HW VLs the port can support, apply a mim/max approach, using a loop
that goes down from the highest possible number of VLs to the lowest,
using the firmware return status to know whether the requested number
of VLs is possible with a given MTU.
For now, as with the dynamic link type change / VPI support, the sysfs
entry to change the mtu is exposed only when NOT running in SR-IOV
mode. To allow changing the MTU for the master in SR-IOV mode,
primary-function-initiated FLR (Function Level Reset) needs to be
implemented.

Commit 22c8bff6face ("mlx4_core: Exported functions can't be static")
fixed most of this up, but forgot about mlx4_is_slave_active(). Fix
this one too.

ConnectX devices have a limit on the number of mappings that can be
done on an FMR before having to call sync_tpt. The current
mlx4_ib driver reports the limit correctly in max_map_per_fmr in
.query_device(), but mlx4_core doesn't check it when actually
allocating FMRs.
Add a max_fmr_maps field to struct mlx4_caps and enforce this maximum
value on FMR allocations.

While doing the work for commit a6f7feae6d ("IB/mlx4: pass SMP
vendor-specific attribute MADs to firmware") we realized that the
firmware would respond on all sorts of vendor-specific MADs.
Therefore commit 97285b7817 ("mlx4_core: Add extended port
capabilities support") adds redundant code into the driver, since
there's no real reaon to maintain the extended capabilities of the
port, as they can be queried on demand (e.g the FDR10 capability).
This patch reverts commit 97285b7817 and removes the check for
extended caps from the mlx4_ib driver port query flow.

Pull irq_domain support for all architectures from Grant Likely:
"Generialize powerpc's irq_host as irq_domain
This branch takes the PowerPC irq_host infrastructure (reverse mapping
from Linux IRQ numbers to hardware irq numbering), generalizes it,
renames it to irq_domain, and makes it available to all architectures.
Originally the plan has been to create an all-new irq_domain
implementation which addresses some of the powerpc shortcomings such
as not handling 1:1 mappings well, but doing that proved to be far
more difficult and invasive than generalizing the working code and
refactoring it in-place. So, this branch rips out the 'new'
irq_domain and replaces it with the modified powerpc version (in a
fully bisectable way of course). It converts all users over to the
new API and makes irq_domain selectable on any architecture.
No architecture is forced to enable irq_domain, but the infrastructure
is required for doing OpenFirmware style irq translations. It will
even work on SPARC even though SPARC has it's own mechanism for
translating irqs at boot time. MIPS, microblaze, embedded x86 and c6x
are converted too.
The resulting irq_domain code is probably still too verbose and can be
optimized more, but that can be done incrementally and is a task for
follow-on patches."
