dm snapshot: fix invalidation deadlock

2007-11-05T17:56:07+00:00

patch fcac03abd325e4f7a4cc8fe05fea2793b1c8eb75 in mainline

Process persistent exception store metadata IOs in a separate thread.

A snapshot may become invalid while inside generic_make_request().
A synchronous write is then needed to update the metadata while still
inside that function.  Since the introduction of
md-dm-reduce-stack-usage-with-stacked-block-devices.patch this has to
be performed by a separate thread to avoid deadlock.

IB/uverbs: Fix checking of userspace object ownership

2007-11-05T17:56:06+00:00

Upstream as cbfb50e6e2e9c580848c0f51d37c24cdfb1cb704

Commit 9ead190b ("IB/uverbs: Don't serialize with ib_uverbs_idr_mutex")
rewrote how userspace objects are looked up in the uverbs module's
idrs, and introduced a severe bug in the process: there is no checking
that an operation is being performed by the right process any more.
Fix this by adding the missing check of uobj->context in __idr_get_uobj().

Apparently everyone is being very careful to only touch their own
objects, because this bug was introduced in June 2006 in 2.6.18, and
has gone undetected until now.

hwmon/w83627hf: Don't assume bank 0

2007-11-02T15:44:15+00:00

Already in Linus' tree:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=d58df9cd788e6fb4962e1c8d5ba7b8b95d639a44

The bank switching code assumes that the bank selector is set to 0
when the driver is loaded. This might not be the case. This is exactly
the same bug as was fixed in the w83627ehf driver two months ago:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=0956895aa6f8dc6a33210967252fd7787652537d

In practice, this bug was causing the sensor thermal types to be
improperly reported for my W83627THF the first time I was loading the
w83627hf driver. From the driver history, I'd say that it has been
broken since September 2005 (when we stopped resetting the chip by
default at driver load.)

hwmon/w83627hf: Fix setting fan min right after driver load

We need to read the fan clock dividers at initialization time,
otherwise the code in store_fan_min() may use uninitialized values.
That's pretty much the same bug and same fix as for the w83627ehf
driver last month.

A stupid bit shifting bug caused the VID value to be always exported
even when the hardware is configured for something different.

Missing parentheses in the definition of FAN_FROM_REG cause a
division by zero for a specific register value.

V4L: ivtv: fix udma yuv bug

2007-11-02T15:44:14+00:00

Based on cb50f548c0ee9b2aac39743fc4021a7188825a98 in mainline

[PATCH] V4L: ivtv: fix udma yuv bug

Using udma yuv causes the driver to become locked into that mode. This
prevents use of the mpeg decoder & non-udma yuv output.

This patch clears the operating mode when the device is closed.

netdrvr: natsemi: Fix device removal bug

2007-11-02T15:44:12+00:00

This episode illustrates how an overused warning can train people to
ignore that warning, which winds up hiding bugs.

The warning

drivers/net/natsemi.c: In function ‘natsemi_remove1’:
drivers/net/natsemi.c:3222: warning: ignoring return value of
‘device_create_file’, declared with attribute warn_unused_result

is oft-ignored, even though at close inspection one notices this occurs
in the /remove/ function, not normally where creation occurs.  A quick
s/create/remove/ and we are fixed, with the warning gone.
