RX support is the only user of the work-queue, to process
reports/notifications from the device. Thus, it needs the work queue
to be initialized first.
Signed-off-by: Inaky Perez-Gonzalez <inaky@linux.intel.com>
Reported and fixed by Cindy H Kao.
When the device is stopped __i2400m_dev_stop() stops the network
queue.
However, when this is done in the middle of heavy network operation,
when the bus-specific subdriver is still wrapping up and it reports a
sent TX transaction with _tx_msg_sent() right after the device was
stopped, the queue was being started again, which was causing a stream
of oopsen and finally a panic.
In any case, said call has no place there. It's a left over from an
early implementation that was discarded later on.
Signed-off-by: Inaky Perez-Gonzalez <inaky@linux.intel.com>
The i2400m driver waits for the device to report being ready for
entering power save before asking it to do so. This module parameter
allows control of said operation; if disabled, the driver won't ask
the device to enter power save mode.
This is useful in setups where power saving is not so important or
when the overhead imposed by network reentry after power save is not
acceptable; by combining this with parameter 'idle_mode_disabled', the
driver will always maintain both the connection and the device in
active state.

This patch is a back-port from aggregation testing code.
In the past, we didn't limit the amount of active tx urbs.
However, ar9170 only has a limited buffer reserved for
pending data frames.
This wasn't much of a problem with the slower 802.11b/g.
We simply stopped the full queue and moved on to something different
in the mean time. But - as you guessed it - this simple approach

A semaphore exists for this purpose, and is now used on these designs. Because
PXE &/or EFI boot code (which we cannot expect to be built with this fix) may
leave the inter-instance semaphore in an invalid initial state when the driver

Michael Tokarev reported receiving a large packet could crash
a machine with RTL8169 NIC.
( original thread at http://lkml.org/lkml/2009/6/8/192 )
Problem is this driver tells that NIC frames up to 16383 bytes
can be received but provides skb to rx ring allocated with
smaller sizes (1536 bytes in case standard 1500 bytes MTU is used)
When a frame larger than what was allocated by driver is received,
dma transfert can occurs past the end of buffer and corrupt
kernel memory.
Fix is to tell to NIC what is the maximum size a frame can be.
This bug is very old, (before git introduction, linux-2.6.10), and
should be backported to stable versions.

This driver does not indicate support for frag lists.
Furthermore, even if it did, the code is walking the frag
lists incorrectly. The idiom is:
for (iter = skb_shinfo(skb)->frag_list; iter; iter = iter->next)
but it's doing:
for (iter = skb_shinfo(skb)->frag_list; iter;
iter = skb_shinfo(iter)->frag_list)
which would never work. And this proves that this driver never
saw an SKB with active frag lists.
So just remove the code altogether and the driver TX path becomes
much simpler.

A driver overhaul on 29 Feb 2000 (!) broke locking around fiddling with
the tx descriptor ring in start_xmit(); a follow-on "fix" removed the
broken remnants altogether. Here's a patch to restore proper locking in
the function -- the complement in the interrupt handler has been correct
all the time.
This *may* have been the reason for the occasional confusion of the chip
-- triggering a tx timeout followed by a chip reset sequence -- seen on
R4k-based DECstations with the onboard Ethernet interface. Another theory
is the confusion is due to an unindentified problem -- perhaps a silicon
erratum -- associated with the variation of the MT ASIC used to interface
the R4k CPU to the rest of the system on these computers; with its
aggressive write-back buffering the design is particularly weakly ordered
when it comes to MMIO (in the absence of ordering barriers uncached reads
are allowed to bypass earlier uncached writes, even if to the same
location), which may trigger all kinds of corner cases in peripheral
hardware as well as software.
Either way this piece of code is buggy.

It is possible for tun_chr_close to race with dellink on the

but dellink runs before tun_chr_close calls unregister_netdevice
we will attempt to unregister the netdevice after it is already
gone.
The two cases are already serialized on the rtnl_lock, so I have
gone for the cheap simple fix of moving rtnl_lock to cover __tun_get
in tun_chr_close. Eliminating the possibility of the tun device
being unregistered between __tun_get and unregister_netdevice in

As all current versions of virtio_net generate a value for the

Through a bug in the tun driver, I noticed that virtio_net is
producing bogus hdr_len values. In particular, it only includes
the IP header in the linear area, and excludes the entire TCP
header. This causes the TCP header to be copied twice for each
packet. (The bug omitted the second copy :)

Each firmware mailbox command can have a different number of
valid data elements. When waiting for a mailbox command to
complete it the process passes it's element count and
waits for the completion. It is possible that while waiting
an unrelated firmware async event (AE) can arrive. When this
happens, the handler will over write the element count
with the value for the newly arrived AE. This can cause
the mailbox command to not get all of it's data.
This patch restores original mailbox count at the end
of the handler.

82599 supports multispeed fiber optical modules (10Gbps/1Gbps). Some
scenarios can cause the autotry mechanism to not negotiate link properly.
What needs to happen is the driver must flap the Tx laser to induce an Rx
Loss of Signal on the link partner. This will restart the autotry
mechanism to get link into a known state. The software definable pin (SDP)
3 on the 0x10fb NIC is wired to cause a Tx LOS event, which triggers the
Rx LOS we require.

Patch fixes the bug at
http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=1903
when SW rfkill is invoked by 'iwconfig txpower off',
the existing connection disassociates and led off command is sent
to the device which returns error as rfkill is 'true'.
Patch fixes this by just avoiding sending the led off/on command when
disassociated. The main purpose of the led_disassociate callback
is to start or stop the blinking.
There are three states in led
1) Always on when radio is on
2) Always off when radio is off
3) blink when associated and if there is some traffic.
In this callback 'allow_blinking' needs to be set false
when associated, as LED will be always on.

This patch completely rewrites the rfkill core to address
the following deficiencies:
* all rfkill drivers need to implement polling where necessary
rather than having one central implementation
* updating the rfkill state cannot be done from arbitrary
contexts, forcing drivers to use schedule_work and requiring
lots of code
* rfkill drivers need to keep track of soft/hard blocked
internally -- the core should do this
* the rfkill API has many unexpected quirks, for example being
asymmetric wrt. alloc/free and register/unregister
* rfkill can call back into a driver from within a function the
driver called -- this is prone to deadlocks and generally
should be avoided
* rfkill-input pointlessly is a separate module
* drivers need to #ifdef rfkill functions (unless they want to
depend on or select RFKILL) -- rfkill should provide inlines
that do nothing if it isn't compiled in
* the rfkill structure is not opaque -- drivers need to initialise
it correctly (lots of sanity checking code required) -- instead
force drivers to pass the right variables to rfkill_alloc()
* the documentation is hard to read because it always assumes the
reader is completely clueless and contains way TOO MANY CAPS
* the rfkill code needlessly uses a lot of locks and atomic
operations in locked sections
* fix LED trigger to actually change the LED when the radio state
changes -- this wasn't done before

It looks like mac80211 can request the driver to start beaconing with
a beacon interval of zero in some cases (at least for mesh point). This
does not sound correct and something may need to be fixed in
mac80211. However, taken into account the unpleasantness of getting
stuck in an infinite busy loop with rtnl_lock held, let's add a quick
workaround in the driver to avoid the worst symptom while someone more
familiar with the mesh implementation can figure out what should be done
with mac80211 as far as beacon interval configuration is concerned.

I have a TrendNet 652-BRP running OpenWRT + ath9k very well. The only
problem is that the beacon gets stuck maybe once a day. After
Vasanthakumar Thiagarajan's "ath9k: cleanup beacon parameters
configuration" patch, ath9k would nearly re-configure the beacons after it
detected the stuck beacon, and did a reset. But it would fail the
SC_OP_TSF_RESET check in ath_beacon_config_ap. This patch gets the beacon
fully reconfigured after the reset.

IMHO this can't work because the SPI driver does not know whether the incomming
bytes are part of the registers/bytes which need to be flipped or part of
packet data which has to remain untouched.
While adding le helpers I also removed spu_write_u32() which has no users.

Patch to fix bad length checking in e1000. E1000 by default does two
things:
1) Spans rx descriptors for packets that don't fit into 1 skb on recieve
2) Strips the crc from a frame by subtracting 4 bytes from the length prior to
doing an skb_put
Since the e1000 driver isn't written to support receiving packets that span
multiple rx buffers, it checks the End of Packet bit of every frame, and
discards it if its not set. This places us in a situation where, if we have a
spanning packet, the first part is discarded, but the second part is not (since
it is the end of packet, and it passes the EOP bit test). If the second part of
the frame is small (4 bytes or less), we subtract 4 from it to remove its crc,
underflow the length, and wind up in skb_over_panic, when we try to skb_put a
huge number of bytes into the skb. This amounts to a remote DOS attack through
careful selection of frame size in relation to interface MTU. The fix for this
is already in the e1000e driver, as well as the e1000 sourceforge driver, but no
one ever pushed it to e1000. This is lifted straight from e1000e, and prevents
small frames from causing the underflow described above

Add a phy_power_down parameter to forcedeth: set to 1 to power down the
phy and disable the link when an interface goes down; set to 0 to always

The phy power state persists across reboots; Windows, some BIOSes, and
older versions of Linux don't bother to power up the phy again, forcing
users to remove all power to get the interface working (see
http://bugzilla.kernel.org/show_bug.cgi?id=13072). Leaving the phy
powered on is the safest default behavior. Users accustomed to seeing
the link state reflect the interface state and/or wanting to minimize
power consumption can set phy_power_down=1 if compatibility with other
OSes is not an issue.

it's only use is to allow ISA and similar primitive bus devices to
have their I/O ports changed via ifconfig. The virtual address is
now stored in the private data structure of the SJA1000 device and
the callback functions use "struct sja1000_priv" instead of the

This patch converts unicast address list to standard list_head using
previously introduced struct netdev_hw_addr. It also relaxes the
locking. Original spinlock (still used for multicast addresses) is not
needed and is no longer used for a protection of this list. All
reading and writing takes place under rtnl (with no changes).
I also removed a possibility to specify the length of the address
while adding or deleting unicast address. It's always dev->addr_len.
The convertion touched especially e1000 and ixgbe codes when the
change is not so trivial.
