netlink_unicast() will attempt to reallocate and will free messages if
the socket's rcvbuf limit is reached unless we give it an infinite
timeout. So do that, from a kernel thread which is dedicated to spewing
stuff up the netlink socket.

* If vsnprintf returns -1, it will mess up the sk buffer space accounting.
This is fixed by not calling skb_put with bogus len values.
* audit_log_hex was a loop that called audit_log_vformat with %02X for each
character. This is very inefficient since conversion from unsigned character
to Ascii representation is essentially masking, shifting, and byte lookups.
Also, the length of the converted string is well known - it's twice the
original. Fixed by rewriting the function.
* audit_log_untrustedstring had no comments. This makes it hard for
someone to understand what the string format will be.
* audit_log_d_path was never fixed to use untrustedstring. This could mess
up user space parsers. This was fixed to make a temp buffer, call d_path,
and log temp buffer using untrustedstring.

It's silly to have to add explicit entries for new userspace messages
as we invent them. Just treat all messages in the user range the same.

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.

Version 2 of the 3com OfficeConnect 11g Cardbus Card aka 3CRWE154G72 is not
