[PATCH] Fix for bttv driver (v0.9.15) for Leadtek WinFast VC100 XP capture cards

2005-06-12T02:45:25+00:00

Cc: kraxel@bytesex.org

This is a tiny patch that fixes bttv-cards.c so that Leadtek WinFast
VC100 XP video capture cards work. I've been advised to post it here
after having already posted it to the v4l mailing list.

[PATCH] ide-disk: Fix LBA8 DMA

2005-05-27T04:20:05+00:00

This is from Gentoo's 2.6.11 patchset. A problem was introduced in 2.6.10
where some users could not enable DMA on their disks (particularly ALi15x3
users). This was a small mistake with the no_lba48_dma flag.

I can't find the exact commit but this is definately included in 2.6.12-rc4.

[PATCH] Fix matroxfb on big-endian hardware

2005-05-27T04:20:05+00:00

There was too much/too few byteswapping done by driver and hardware in
matroxfb on big endian hardware.  Change fixes mirrored/split/corrupted
letters seen on screen when using accelerated matroxfb mode.

Patch was tested on Mips (by Peter) and x86-64 (by Petr).

During a warm boot the device is in D3 and has troubles coming out of it.

[PATCH] Fix root hole in pktcdvd

2005-05-16T17:45:48+00:00

ioctl_by_bdev may only be used INSIDE the kernel.  If the "arg" argument
refers to memory that is accessed by put_user/get_user in the ioctl
function, the memory needs to be in the kernel address space (that's the
set_fs(KERNEL_DS) doing in the ioctl_by_bdev).  This works on i386 because
even with set_fs(KERNEL_DS) the user space memory is still accessible with
put_user/get_user.  That is not true for s390.  In short the ioctl
implementation of the pktcdvd device driver is horribly broken.

[PATCH] Fix root hole in raw device

2005-05-16T17:42:14+00:00

[Patch] Fix raw device ioctl pass-through

Raw character devices are supposed to pass ioctls through to the block
devices they are bound to.  Unfortunately, they are using the wrong
function for this: ioctl_by_bdev(), instead of blkdev_ioctl().

ioctl_by_bdev() performs a set_fs(KERNEL_DS) before calling the ioctl,
redirecting the user-space buffer access to the kernel address space.
This is, needless to say, a bad thing.

This was noticed first on s390, where raw IO was non-functioning.  The
s390 driver config does not actually allow raw IO to be enabled, which
was the first part of the problem.  Secondly, the s390 kernel address
space is distinct from user, causing legal raw ioctls to fail.  I've
reproduced this on a kernel built with 4G:4G split on x86, which fails
in the same way (-EFAULT if the address does not exist kernel-side;
returns success without actually populating the user buffer if it does.)

The patch below fixes both the config and address-space problems.  It's
based closely on a patch by Jan Glauber , which has
been tested on s390 at IBM.  I've tested it on x86 4G:4G (split address
space) and x86_64 (common address space).

Kernel-address-space access has been assigned CAN-2005-1264.

[PATCH] I2C: Fix incorrect sysfs file permissions in it87 and via686a drivers

2005-05-12T17:00:24+00:00

The it87 and via686a hardware monitoring drivers each create a sysfs
file named "alarms" in R/W mode, while they should really create it in
read-only mode. Since we don't provide a store function for these files,
write attempts to these files will do something undefined (I guess) and
bad (I am sure). My own try resulted in a locked terminal (where I
attempted the write) and a 100% CPU load until next reboot.

As a side note, wouldn't it make sense to check, when creating sysfs
files, that readable files have a non-NULL show method, and writable
files have a non-NULL store method? I know drivers are not supposed to
do stupid things, but there is already a BUG_ON for several conditions
in sysfs_create_file, so maybe we could add two more?

Revert the msdos.c patch as it causes more problems than it helps right now.
(it got munged together with the i2c patch also, stupid scripts...)
