pxa168_eth: fix error handling in prope
A couple issues here:
* Some resources weren't released.
* If alloc_etherdev() failed it would have caused a NULL dereference
because "pep" would be null when we checked "if (pep->clk)".
* Also it's better to propagate the error codes from mdiobus_register()
instead of just returning -ENOMEM.

"pep->pd" isn't checked consistently in this function. For example it's
dereferenced unconditionally on the next line after the end of the if

pep->pd is always non-NULL so I removed the check.

phylib: Fix race between returning phydev and calling adjust_link
It is possible that phylib will call adjust_link before returning
from {,of_}phy_connect(), which may cause the following [very rare,
though] oops upon reopening the device:

Here is why. Drivers store phydev in their private structures, e.g.
gianfar driver:
static int init_phy(struct net_device *dev)
{
...
priv->phydev = of_phy_connect(...);
...
}
So that adjust_link could retrieve it back:
static void adjust_link(struct net_device *dev)
{
...
struct phy_device *phydev = priv->phydev;
...
}
If the device has been opened before, then phydev->state is set to
PHY_HALTED (or undefined if the driver didn't call phy_stop()).
Now, phy_connect starts the PHY state machine before returning phydev to
the driver:
phy_start_machine(phydev, NULL);
if (phydev->irq > 0)
phy_start_interrupts(phydev);
return phydev;
The time between 'phy_start_machine()' and 'return phydev' is undefined.
The start machine routine delays execution for 1 second, which is enough
for most cases. But under heavy load, or if you're unlucky, it is quite
possible that PHY state machine will execute before phy_connect()
returns, and so adjust_link callback will try to dereference phydev,
which is not yet ready.
To fix the issue, simply initialize the PHY's state to PHY_READY during
phy_attach(). This will ensure that phylib won't call adjust_link before
phy_start().

3c59x: Fix deadlock between boomerang_interrupt and boomerang_start_tx
If netconsole is in use, there is a possibility for deadlock in 3c59x between
boomerang_interrupt and boomerang_start_xmit. Both routines take the vp->lock,
and if netconsole is in use, a pr_* call from the boomerang_interrupt routine
will result in the netconsole code attempting to trnasmit an skb, which can try
to take the same spin lock, resulting in deadlock.
The fix is pretty straightforward. This patch allocats a bit in the 3c59x
private structure to indicate that its handling an interrupt. If we get into
the transmit routine and that bit is set, we can be sure that we have recursed
and will deadlock if we continue, so instead we just return NETDEV_TX_BUSY, so
the stack requeues the skb to try again later.

ehea: Fix synchronization between HW and SW send queue
When memory is added to / removed from a partition via the Memory DLPAR
mechanism, the eHEA driver has to do a couple of things to reflect the

stopping and restarting the HW queues.
During this operation, it is possible that HW and SW pointer into these
queues get out of sync. This results in a situation where packets that
are attached to a send queue are not transmitted immediately, but
delayed until further X packets have been put on the queue.

net/compat/wext: send different messages to compat tasks
we had a race condition when setting and then
restoring frag_list. Eric attempted to fix it,
but the fix created even worse problems.
However, the original motivation I had when I
added the code that turned out to be racy is
no longer clear to me, since we only copy up
to skb->len to userspace, which doesn't include
the frag_list length. As a result, not doing
any frag_list clearing and restoring avoids
the race condition, while not introducing any
other problems.
Additionally, while preparing this patch I found
that since none of the remaining netlink code is
really aware of the frag_list, we need to use the
original skb's information for packet information
and credentials. This fixes, for example, the
group information received by compat tasks.

ath5k: disable ASPM L0s for all cards
Atheros PCIe wireless cards handled by ath5k do require L0s disabled.
For distributions shipping with CONFIG_PCIEASPM (this will be enabled
by default in the future in 2.6.36) this will also mean both L1 and L0s
will be disabled when a pre 1.1 PCIe device is detected. We do know L1
works correctly even for all ath5k pre 1.1 PCIe devices though but cannot
currently undue the effect of a blacklist, for details you can read
pcie_aspm_sanity_check() and see how it adjusts the device link
capability.
It may be possible in the future to implement some PCI API to allow
drivers to override blacklists for pre 1.1 PCIe but for now it is
best to accept that both L0s and L1 will be disabled completely for
distributions shipping with CONFIG_PCIEASPM rather than having this
issue present. Motivation for adding this new API will be to help
with power consumption for some of these devices.
Example of issues you'd see:
- On the Acer Aspire One (AOA150, Atheros Communications Inc. AR5001
Wireless Network Adapter [168c:001c] (rev 01)) doesn't work well
with ASPM enabled, the card will eventually stall on heavy traffic
with often 'unsupported jumbo' warnings appearing. Disabling
ASPM L0s in ath5k fixes these problems.
- On the same card you would see a storm of RXORN interrupts
even though medium is idle.

Bluetooth: Use 3-DH5 payload size for default ERTM max PDU size
The previous value of 672 for L2CAP_DEFAULT_MAX_PDU_SIZE is based on
the default L2CAP MTU. That default MTU is calculated from the size
of two DH5 packets, minus ACL and L2CAP b-frame header overhead.
ERTM is used with newer basebands that typically support larger 3-DH5
packets, and i-frames and s-frames have more header overhead. With
clean RF conditions, basebands will typically attempt to use 1021-byte
3-DH5 packets for maximum throughput. Adjusting for 2 bytes of ACL
headers plus 10 bytes of worst-case L2CAP headers yields 1009 bytes
of payload.
This PDU size imposes less overhead for header bytes and gives the
baseband the option to choose 3-DH5 packets, but is small enough for
ERTM traffic to interleave well with other L2CAP or SCO data.
672-byte payloads do not allow the most efficient over-the-air
packet choice, and cannot achieve maximum throughput over BR/EDR.

Bluetooth: Fix incorrect setting of remote_tx_win for L2CAP ERTM
remote_tx_win is intended to be set on receipt of an L2CAP
configuration request. The value is used to determine the size of the
transmit window on the remote side of an ERTM connection, so L2CAP
can stop sending frames when that remote window is full.
An incorrect remote_tx_win value will cause the stack to not fully
utilize the tx window (performance impact), or to overfill the remote
tx window (causing dropped frames or a disconnect).
This patch removes an extra setting of remote_tx_win when a

iwlagn: fix rts cts protection
Currently the driver will try to protect all frames,
which leads to a lot of odd things like sending an
RTS with a zeroed RA before multicast frames, which
is clearly bogus.
In order to fix all of this, we need to take a step
back and see what we need to achieve:
* we need RTS/CTS protection if requested by
the AP for the BSS, mac80211 tells us this
* in that case, CTS-to-self should only be
enabled when mac80211 tells us
* additionally, as a hardware workaround, on
some devices we have to protect aggregated
frames with RTS
To achieve the first two items, set up the RXON
accordingly and set the protection required flag
in the transmit command when mac80211 requests
protection for the frame.
To achieve the last item, set the rate-control
RTS-requested flag for all stations that we have
aggregation sessions with, and set the protection
required flag when sending aggregated frames (on
those devices where this is required).
Since otherwise bugs can occur, do not allow the
user to override the RTS-for-aggregation setting
from sysfs any more.
Finally, also clean up the way all these flags get
set in the driver and move everything into the
device-specific functions.

e100/e1000*/igb*/ixgb*: Add missing read memory barrier
Based on patches from Sonny Rao and Milton Miller...
Combined the patches to fix up clean_tx_irq and clean_rx_irq.
The PowerPC architecture does not require loads to independent bytes
to be ordered without adding an explicit barrier.
In ixgbe_clean_rx_irq we load the status bit then load the packet data.
With packet split disabled if these loads go out of order we get a
stale packet, but we will notice the bad sequence numbers and drop it.
The problem occurs with packet split enabled where the TCP/IP header
and data are in different descriptors. If the reads go out of order
we may have data that doesn't match the TCP/IP header. Since we use
hardware checksumming this bad data is never verified and it makes it
all the way to the application.
This bug was found during stress testing and adding this barrier has
been shown to fix it. The bug can manifest as a data integrity issue
(bad payload data) or as a BUG in skb_pull().
This was a nasty bug to hunt down, if people agree with the fix I think
it's a candidate for stable.
Previously Submitted to e1000-devel only for ixgbe
http://marc.info/?l=e1000-devel&m=

net: disable preemption before call smp_processor_id()
Although netif_rx() isn't expected to be called in process context with
preemption enabled, it'd better handle this case. And this is why get_cpu()
is used in the non-RPS #ifdef branch. If tree RCU is selected,
rcu_read_lock() won't disable preemption, so preempt_disable() should be
called explictly.

tcp: no md5sig option size check bug
tcp_parse_md5sig_option doesn't check md5sig option (TCPOPT_MD5SIG)
length, but tcp_v[46]_inbound_md5_hash assume that it's at least 16
bytes long.

iwlwifi: fix locking assertions
spin_is_locked() can return zero on some (UP?)
configurations because locks don't exist, and
that causes an endless amount of warnings. Use
lockdep_assert_held() instead, which has two
advantages:
1) it verifies the current task is holding
the lock or mutex
2) it compiles away completely when lockdep
is not enabled

iwlwifi: fix TX tracer
The TX tracing code copies with the wrong length,
which will typically copy too little data. Fix
this by using the correct length variable.

isdn: fix information leak
The main motivation of this patch changing strcpy() to strlcpy().
We strcpy() to copy a 48 byte buffers into a 49 byte buffers. So at
best the last byte has leaked information, or maybe there is an
overflow? Anyway, this patch closes the information leaks by zeroing
the memory and the calls to strlcpy() prevent overflows.
