commit 37efa239901493694a48f1d6f59f8de17c2c4509 upstream.
We must not use the device DMA addresses for the kernel DMA API, because
device DMA addresses have an additional offset added for the SSB translation.
Use the original dma_addr_t for the sync operation.

upstream commit: d78ad8cbfe73ad568de38814a75e9c92ad0a907c
Original comment (Karsten):
On a MSI MS-6702E mainboard, when in rtl8169_init_one() for the first time
after BIOS has run, IntrStatus reads 5 after chip has been reset.
IntrStatus should equal 0 there, so patch changes IntrStatus reset to happen
after chip reset instead of before.
Remark (Francois):
Assuming that the loglevel of the driver is increased above NETIF_MSG_INTR,
the bug reveals itself with a typical "interrupt 0025 in poll" message
at startup. In retrospect, the message should had been read as an hint of
an unexpected hardware state several months ago :o(

upstream commit: a3c0b87c4f21911fb7185902dd13f0e3cd7f33f7
This patch fixes the return type of b43_plcp_get_bitrate_idx_ofdm. If
the plcp contains an error, the function return value is 255 instead
of -1, and the packet was not dropped. This causes a warning in
__ieee80211_rx function because rate idx is out of range.

The un-refactored code checked the link speed and duplex of
every slave on every pass; the refactored code did not do so.
The 802.3ad and balance-alb/tlb modes utilize the speed and
duplex information, and require it to be kept up to date. This patch

commit cac477e8f1038c41b6f29d3161ce351462ef3df7 upstream.
The Ericsson F3507g wireless broadband module provides a CDC Ethernet
compliant interface, but identifies it as a "Mobile Direct Line" CDC
subclass, thereby preventing the CDC Ethernet class driver from picking
it up. This patch adds the device id to cdc_ether.c as a workaround.
Ericsson has provided a "class" driver for this device:
http://kerneltrap.org/mailarchive/linux-net/2008/10/28/3832094
But closer inspection of that driver reveals that it adds little more
than duplication of code from cdc_ether.c. See also

802.1Q expanded the maximum ethernet frame size by 4 bytes for the
VLAN tag. We're not taking this into account in virtio_net, which
means the buffers we provide to the backend in the virtqueue RX ring
aren't big enough to hold a full MTU VLAN packet. For QEMU/KVM,
this results in the backend exiting with a packet truncation error.

[ Upstream commit cfbf84fcbcda98bb91ada683a8dc8e6901a83ebd ]
Tap devices can make use of a small MAC filter set via the
TUNSETTXFILTER ioctl. The filter has a set of exact matches
plus a hash for imperfect filtering of additional multicast
addresses. The current code is unbalanced, adding unicast
addresses to the multicast hash, but only checking the hash
against multicast addresses. This results in the filter
dropping unicast addresses that overflow the exact filter.
The fix is simply to disable the filter by leaving count set
to zero if we find non-multicast addresses after the exact
match table is filled.

[ Upstream commit 71822faa3bc0af5dbf5e333a2d085f1ed7cd809f ]
From: Ilkka Virta <itvirta@iki.fi>
In the lockup situation the driver seems to go off in an eternal storm
of interrupts right after calling request_irq(). It doesn't actually
do anything interesting in the interrupt handler. Since connecting the link
afterwards works, something later in initialization must fix this.
Looking at gem_do_start() and gem_open(), it seems that the only thing
done while opening the device after the request_irq(), is a call to
napi_enable().
I don't know what the ordering requirements are for the
initialization, but I boldly tried to move the napi_enable() call
inside gem_do_start() before the link state is checked and interrupts
subsequently enabled, and it seems to work for me. Doesn't even break
anything too obvious...

commit 14a4dfe2ff8c353f59ae8324059ded1cfe22c7d9 upstream.
This patch fixes sporadic firmware restarts when scanning while associated.
The firmware will quietly cancel a scan (while associated) if the dwell time
for a channel to be scanned is larger than the time it may stay away from the
operating channel (because of DTIM catching). Unfortunately the driver is not
notified about the canceled scan and therefore the scan watchdog timeout will
be hit and the driver causes a firmware restart which results in
disassociation. This mainly happens on passive channels which use a dwell time
of 120 whereas a typical beacon interval is around 100.
The patch changes the dwell time for passive channels to be slightly smaller
than the actual beacon interval to work around the firmware issue. Furthermore
the number of allowed beacon misses is increased from one to three as otherwise
most scans (while associated) won't complete successfully.
However scanning while associated will still fail in corner cases such as a
beacon intervals below 30.

A nasty bug was found where an MTU change (or anything else that caused a
reset) could race with the interrupt code. The interrupt code was entered
by a shared interrupt during the MTU change.
This change prevents the interrupt code from running while the driver is in
the middle of its reset path.

commit dd397dc9dddfa2149a1bbc9e52ac7d5630737cec upstream
Alan Stern found several flaws in p54usb's implementation and annotated:
"usb_kill_urb() and similar routines do not expect an URB's completion
routine to deallocate it. This is almost obvious -- if the URB is deallocated
before the completion routine returns then there's no way for usb_kill_urb
to detect when the URB actually is complete."
This patch addresses all known limitations in the old implementation and fixes
khub's "use-after-freed" hang, when SLUB debug's poisoning option is enabled.

this is filled with all support rate from assoc_resp. If we associate
with G-band AP only supp_rates of G-band will be set the other band
supp_rates will be set to 0. If the user type this command
this will cause mac80211 to set to new channel, mac80211
does not disassociate in setting new channel, so the active
band is now A-band. then in handling the new essid mac80211 will
kick in the assoc steps which involve sending disassociation frame.
in this mac80211 will WARN_ON sta->supp_rates[A_BAND] == 0.

commit eb83bbf57429ab80f49b413e3e44d3b19c3fdc5a upstream.
After reports of poor performance, a review of the latest vendor driver
(rtl8187_linux_26.1025.0328.2007) for RTL8187L devices was undertaken.
A difference was found in the code used to index the OFDM power tables. When
the Linux driver was changed, my unit works at a much greater range than
before. I think this fixes Bugzilla #12380 and has been tested by at least
two other users.

Else, the firmware could freeze, or simply drop the frame.

We're doing an sprintf of an 11-char string into an 11-char buffer.
Whoops. It breaks firmware uploading.

commit 8b0162a3dc5c30e862b7a73da29e32de3170f5e4 upstream.
Noise floor calibration occasionally fails on Atheros hardware.
This is not fatal and can happen if there's simply too much
noise on the air. Ignoring the calibration error is the right
thing to do here, because when the error is ignored, the hardware
will still work, whereas if the error causes the driver to bail out
of a bigger configuration function and does not configure the tx
queues or the IMR (as is the case in reset.c), the hw no longer
works properly until the next reset.

commit f1bc4ac61f2c08515afd80c6dc3962aa6d0b138b upstream.
Previously we allocate Rx SKB with GFP_ATOMIC flag. This is because we need
to hold a spinlock to protect the two rx_used and rx_free lists operation
in the rxq.
spin_lock();
...
element = rxq->rx_used.next;
element->skb = alloc_skb(..., GFP_ATOMIC);
list_del(element);
list_add_tail(&element->list, &rxq->rx_free);
...
spin_unlock();
After spliting the rx_used delete and rx_free insert into two operations,
we don't require the skb allocation in an atomic context any more (the
function itself is scheduled in a workqueue).
spin_lock();
...
element = rxq->rx_used.next;
list_del(element);
...
spin_unlock();
...
element->skb = alloc_skb(..., GFP_KERNEL);
...
spin_lock()
...
list_add_tail(&element->list, &rxq->rx_free);
...
spin_unlock();
This patch should fix the "iwlagn: Can not allocate SKB buffers" warning
we see recently.

This patch fixes a segfault in ppp_shutdown_interface() and
ppp_destroy_interface() when a PPP connection is closed. I bisected
the problem to the following commit:
commit c8019bf3aff653cceb64f66489fc299ee5957b57
Author: Wang Chen <wangchen@cn.fujitsu.com>
Date: Thu Nov 20 04:24:17 2008 -0800
netdevice ppp: Convert directly reference of netdev->priv
1. Use netdev_priv(dev) to replace dev->priv.
2. Alloc netdev's private data by alloc_netdev().
Signed-off-by: Wang Chen <wangchen@cn.fujitsu.com>
Signed-off-by: David S. Miller <davem@davemloft.net>
The original ppp_generic code treated the netdev and struct ppp as
independent data structures which were freed separately. In moving the
ppp struct into the netdev, it is now possible for the private data to
be freed before the call to ppp_shutdown_interface(), which is bad.
The kfree(ppp) in ppp_destroy_interface() is also wrong; presumably
ppp hasn't worked since the above commit.
The following patch fixes both problems.

kernel BUG at drivers/net/phy/mdio_bus.c:165!
Unable to handle kernel NULL pointer dereference at virtual address 00000000
How?
mdiobus_alloc() sets bus->state = MDIOBUS_ALLOCATED.
mdiobus_register() sets bus->state = MDIOBUS_REGISTERED but then can
fail (mdiobus_scan()) returning an error to the caller.
The caller aborts correctly with mdiobus_free() which does:
if (bus->state == MDIOBUS_ALLOCATED) {
kfree(bus);
return;
}
BUG_ON(bus->state != MDIOBUS_UNREGISTERED);

The enc28j60 driver reads incoming packets in the process (workqueue) context,
not in a tasklet or the interrupt context. Thus, we should use netif_rx_ni()
to deliver those packets to the networking layer, instead of netif_rx(). This
way incoming packets don't wait in the incoming queue for the next IRQ to be
serviced.

The TLAN chip does not support tranmissions smaller than 64
bytes. Smaller transfers need to be padded up to that size. This was

During a reset, releasing the swflag after it failed to be acquired would
cause a double unlock of the mutex. Instead, test whether acquisition of
the swflag was successful and if not, do not release the swflag. The reset
must still be done to bring the device to a quiescent state.

From: Hermann Lauer <Hermann.Lauer@iwr.uni-heidelberg.de>
Attached is a patch which improves the output of ethtool (see below)
to some sensefull values with a sungem fibre card which uses the
sungem interal pcs connected to a serdes chip. The seriallink case in
the driver is untouched.
Most values are hardcoded, because gigabit fibre autoneg is anyways
limited and the driver don't really support much at the moment with
that hardware.
