iwl3945: fix possible il->txq NULL pointer dereference in delayed works

2012-03-23T18:20:52+00:00

commit 210787e82a0ac1ffb5d7be1c796f0c51050849ad upstream.

On il3945_down procedure we free tx queue data and nullify il->txq
pointer. After that we drop mutex and then cancel delayed works. There
is possibility, that after drooping mutex and before the cancel, some
delayed work will start and crash while trying to send commands to
the device. For example, here is reported crash in
il3945_bg_reg_txpower_periodic():
https://bugzilla.kernel.org/show_bug.cgi?id=42766#c10

Patch fix problem by adding il->txq check on works that send commands,
hence utilize tx queue.

i2c-algo-bit: Fix spurious SCL timeouts under heavy load

2012-03-19T15:57:59+00:00

commit 8ee161ce5e0cfc689eb677f227a6248191165fac upstream.

When the system is under heavy load, there can be a significant delay
between the getscl() and time_after() calls inside sclhi(). That delay
may cause the time_after() check to trigger after SCL has gone high,
causing sclhi() to return -ETIMEDOUT.

To fix the problem, double check that SCL is still low after the
timeout has been reached, before deciding to return -ETIMEDOUT.

hwmon: (w83627ehf) Fix memory leak in probe function

2012-03-19T15:57:59+00:00

commit 32260d94408c553dca4ce54104edf79941a27536 upstream.

The driver probe function leaked memory if creating the cpu0_vid attribute file
failed. Fix by converting the driver to use devm_kzalloc.

hwmon: (w83627ehf) Fix writing into fan_stop_time for NCT6775F/NCT6776F

2012-03-19T15:57:59+00:00

commit 33fa9b620409edfc71aa6cf01a51f990fbe46ab8 upstream.

NCT6775F and NCT6776F have their own set of registers for FAN_STOP_TIME. The
correct registers were used to read FAN_STOP_TIME, but writes used the wrong
registers. Fix it.

compat: Re-add missing asm/compat.h include to fix compile breakage on s390

2012-03-19T15:57:59+00:00

For 3.0 stable kernel the backport of 048cd4e51d24ebf7f3552226d03c769d6ad91658
"compat: fix compile breakage on s390" breaks compilation...

Re-add a single #include  in order to fix this.

This patch is _not_ necessary for upstream, only for stable kernels
which include the "build fix" mentioned above.

One fix for arch/s390/kernel/setup.c was already sent and applied. But
we need a similar patch for drivers/s390/char/fs3270.c.

sfc: Fix assignment of ip_summed for pre-allocated skbs

2012-03-19T15:57:59+00:00

commit ff3bc1e7527504a93710535611b2f812f3bb89bf upstream.

When pre-allocating skbs for received packets, we set ip_summed =
CHECKSUM_UNNCESSARY.  We used to change it back to CHECKSUM_NONE when
the received packet had an incorrect checksum or unhandled protocol.

Commit bc8acf2c8c3e43fcc192762a9f964b3e9a17748b ('drivers/net: avoid
some skb->ip_summed initializations') mistakenly replaced the latter
assignment with a DEBUG-only assertion that ip_summed ==
CHECKSUM_NONE.  This assertion is always false, but it seems no-one
has exercised this code path in a DEBUG build.

Fix this by moving our assignment of CHECKSUM_UNNECESSARY into
efx_rx_packet_gro().

atl1c: dont use highprio tx queue

2012-03-19T15:57:46+00:00

[ Upstream commit 11aad99af6ef629ff3b05d1c9f0936589b204316 ]

This driver attempts to use two TX rings but lacks proper support :

1) IRQ handler only takes care of TX completion on first TX ring
2) the stop/start logic uses the legacy functions (for non multiqueue
drivers)

This means all packets witk skb mark set to 1 are sent through high
queue but are never cleaned and queue eventualy fills and block the
device, triggering the infamous "NETDEV WATCHDOG" message.

Lets use a single TX ring to fix the problem, this driver is not a real
multiqueue one yet.

Minimal fix for stable kernels.
