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 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 <jang@de.ibm.com>, 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.

This has been a problem for me for ages. When using bridging, the driver
is switched into promiscuous mode before the link init is complete. The
init complete routine then resets the promisc bit on the card so the kernel
still thinks the card is in promiscuous mode but the card isn't. doh.
I think this bug only shows up in bridging when the bridge is started at
boot time (or something else that sets promisc at the same time the card
was started). If promisc is enabled later it works.
Here's a trivial (and hopefully correct) patch that works for me. It
just calls the promisc/multicast setup routine after init.

===================================================================
Problem:
During the libata CD-ROM stress test, sometimes the "BUG: timeout
without command" error is seen.
Root cause:
Unexpected interrupt occurs after the ata_qc_complete() is called,
but before the SCSI error handler. The interrupt handler is invoked
before the SCSI error handler, and it clears the command by calling
ata_qc_complete() again. Later when the SCSI error handler is run,
the ata_queued_cmd is already gone, causing the "BUG: timeout without
command" error.
Changes:
- Use the ATA_QCFLAG_ACTIVE flag to prevent the interrupt handler
from completing the command twice, before the scsi_error_handler.

This patch brings the airo driver into line with the current
WEXT specification of signal quality. It also fixes the values
used to determine signal quality and level for MPI & PCMCIA 350
cards. It turns out that BSSListRid.rssi was actually in dBm
for 350 series cards, and that we can use the normalized
signal strength reported by the card as our "quality" value, on
a scale of 0 - 100. Since signal level values are in dBm for
this driver, max_qual->level MUST be 0, as specified in the WEXT
spec. This patch also uses the IW_QUAL constants new in WEXT
version 17.

The patch adds proper handling.
The patch also removes the code that drops all packets with RX_ERROR &
(!RX_FRAMINGERR): ERROR4 errors are also not fatal.
Hi Andrew, Jeff,
The iseries_veth driver is badly behaved in that it will keep TX packets
hanging around forever if they're not ACK'ed and the queue never fills up.
This causes the unregister_netdevice code to wait forever when we try to take
the device down, because there's still skbs around with references to our
struct net_device.
There's already code to cleanup any un-ACK'ed packets in veth_stop_connection()
but it's being called after we unregister the net_device, which is too late.
The fix is to rearrange the module exit function so that we cleanup any
outstanding skbs and then unregister the driver.

The iseries_veth driver doesn't set dev->trans_start in it's TX path. This

Hi Andrew, Jeff,
The iseries_veth driver has a logic bug which means it will erroneously
send packets to LPARs for which we don't have a connection.
This usually isn't a big problem because the Hypervisor call fails
gracefully and we return, but if packets are TX'ed during the negotiation
of the connection bad things might happen.
Regardless, the right thing is to bail early if we know there's no
connection.

There's a slight bug in the routines in that if the period requires dt,
then the routine will unconditionally set it. DT may only be set if
Wide is also set, so this turns back on the wide bit.
For domain validation to work correctly, we need to observe the wide bit
absolutely.

Attached is a patch to bttv which fixes the following problems.
Affected cards and problems:
~~~~~~~~~~~~~~~~~~~~~~~~
o VP-1020 (200103A) Tuning problems, device detection.
o VP-1020 (DST-MOT) Errors during tuning, device detection fails in a while.
o VP-1030 (DST-CI) Tuning sometimes fails after CI commands.
o VP-2031 (DCT-CI) Tuning problems
The timeout happens before the actual timeout occured in the MCU
on the board, and hence the problems.
Changes: (bttv-i2c.diff)
~~~~~~~~~~~~~~~~~~~~~~~~
o Changed the custom wait queue to wait_event_interruptible_timeout()
- Suggestion by Johannes Stezenbach.
o Fixed the wait queue timeout problem
- This fixes the timeout problem on various cards.
- This problem was visible as many
* Cannot tune to channels, when signal levels are very low.
* app_info does not work in some conditions for CI based cards
- Smaller values worked good for newer cards, but the older cards
suffered, settled down to the worst case values that could happen in any
eventuality.

This patch adds support for a new class of DAC960 controllers. It's based
on the GPLed idac320 driver from IBM for Linux 2.4.18. That driver is a
fork of the 2.4.18 version of DAC960 that adds support for this new type of
controllers (internally called "GEM Series"), that differ from other DAC960
V2 firmware controllers only in the register offsets and removes support
for all others.
This patch instead integrates support for these controllers into the DAC960
driver.
Thanks to Anders Norrbring for pointing me to the idac320 driver and
testing this patch.
No Signed-Off: line because all code is either copy & pasted from IBM's
idac320 driver or support for other controllers in the 2.6 DAC960 driver.
Note: the really odd formating matches the rest of the DAC960 driver.

The premise is that domain validation is likely to trigger errors which

when it gets a unit attention (likely as the result of a previous bus or

all cases except those of unit attention. The attached fixes this to do

With 2.6.11 and 2.6.12-rc2 (and perhaps a few versions before) usb
drivers for multi-interface devices, which do
usb_driver_release_interface() in their disconnect(), make rmmod hang.
It turns out to be due to a bug in drivers/base/bus.c:driver_detach(),
that iterates over the list of attached devices with
list_for_each_safe() under an assumption that device_release_driver()
only releases the current device, while it may also call
device_release_driver() for other devices on the same list.

Miscellaneous updates for EHCI.
- Mostly updates the power switching on EHCI controllers. One routine

do that is reported more correctly.
- Courtesy Colin Leroy, a patch to always power up ports after resumes
which didn't keep a USB device suspended. The reset-everything logic
powers down those ports (on some hardware) so something needs to turn
them back on.

I have recompiled Linux kernel 2.6.11.5 documentation for me and our
university students again. The documentation could be extended for more
sources which are equipped by structured comments for recent 2.6 kernels. I
have tried to proceed with that task. I have done that more times from 2.6.0
time and it gets boring to do same changes again and again. Linux kernel
compiles after changes for i386 and ARM targets. I have added references to
some more files into kernel-api book, I have added some section names as well.
So please, check that changes do not break something and that categories are
not too much skewed.
I have changed kernel-doc to accept "fastcall" and "asmlinkage" words reserved
by kernel convention. Most of the other changes are modifications in the
comments to make kernel-doc happy, accept some parameters description and do
not bail out on errors. Changed <pid> to @pid in the description, moved some
#ifdef before comments to correct function to comments bindings, etc.
You can see result of the modified documentation build at
http://cmp.felk.cvut.cz/~pisa/linux/lkdb-2.6.11.tar.gz

documentation. Sources has been added into kernel-api for now. Some more

Enable interrupts for a BT interface. There is a specific register that
needs to be set up to enable interrupts that also must be modified to clear
the irq.
Also, don't reset the BMC on a BT interface. That's probably not a good
idea as the BMC may be performing other important functions and a reset
should only be a last resort. Also, that register is also used to
enable/disable interrupts to the BT; modifying it may screw up the
interrupts.

There were still a few comments left refering to verify_area, and two
functions, verify_area_skas & verify_area_tt that just wrap corresponding
access_ok_skas & access_ok_tt functions, just like verify_area does for
access_ok - deprecate those.
There was also a few places that still used verify_area in commented-out

After applying this one there should not be anything left but finally
removing verify_area completely, which will happen after a kernel release

When allocating a new VC with vgacon_init(), the font is shared across all
the VGA consoles. However, the font mask was always set to the default
value of zero in visual_init(), even if we were using 512 character fonts
at the time.
Moreover, code in vgacon.c:vga_do_font_op() didn't reset the mask if the
console driver thinks it's already in 512 character mode. This means that
to *fix* it, you'd actually have to take the console out of 512 character
mode and then set it back.
The attached sets vc_hi_font_mask in vgacon_init() for any new consoles
opened if the vgacon driver is already in 512 character mode, solving this.
This bug goes back to 2.4.18 at least, probably earlier.

This is take two of a patch that should have appeared two days ago, before
yesterday's "remote control" patch for the same card.
This patch sets unconnected GPIO to Output to keep them from floating (just
good driver writing practice, being nice to the chip), and uses GPIO16 to
switch TV vs. FM - this pin switches inputs onto the tuner, as well as the
audio output from the tuner into the 7135 SIF input. Consequently, FM
radio support is being un-commented because it's now working (sort of, see
below).
These two patches get the card almost fully operational; there appears to
be a bug in tda8290.c remaining that puts an offset onto the tuned
frequency in FM radio mode. We're investigating.

I noticed an occasional crash on wakeup from sleep on my powerbook
(strangly never happened before, probably timing related) that appears to
be due to a dangling interrupt while the chip is put to sleep and beeing
reset on wakeup.
This patch fixes is by disabling the irq in the ide pmac driver while
asleep and only re-enable it after the chip has been fully reset. This is
safe to do so as the interrupt of these apple IDE cells is never shared.
