Replace old naive extract-8-lsb-bits algorithm with a better
algorithm xor'ing 3 or 4 bit fields at the size of the hashtable
array index in order to improve distribution if the majority of
the lower bits are unused while keeping zero collision behaviour

The SELinux hooks invoke ipv6_skip_exthdr() with an incorrect
length final argument. However, the length argument turns out
to be superfluous.
I was just reading ipv6_skip_exthdr and it occured to me that we can
get rid of len altogether. The only place where len is used is to
check whether the skb has two bytes for ipv6_opt_hdr. This check
is done by skb_header_pointer/skb_copy_bits anyway.
Now it might appear that we've made the code slower by deferring
the check to skb_copy_bits. However, this check should not trigger
in the common case so this is OK.

The NAT changes in 2.6.11 changed the position where helpers
are called and perform packet mangling. Before 2.6.11, a NAT
helper was called before the packet was NATed and had its
sequence number adjusted. Since 2.6.11, the helpers get packets
with already adjusted sequence numbers.
This breaks sequence number adjustment, adjust_tcp_sequence()
needs the original sequence number to determine whether
a packet was a retransmission and to store it for further
corrections. It can't be reconstructed without more information
than available, so this patch restores the old order by
calling helpers from a new conntrack hook two priorities
below ip_conntrack_confirm() and adjusting the sequence number
from a new NAT hook one priority below ip_conntrack_confirm().

This is a somewhat more comprehensive fix for the problem of devices
like the newer Zaurii ... or in this case some Motorola cell phones.
To recap, the problem's root cause is that these devices aren't using
standard USB class specifications for their network links, and so far
we've had to add lots of device-specific driver entries. The vendor
fix abuses the CDC MDLM descriptors (they _could_ have conformed to
the spec, but didn't) and defines a "Belcarra firmware" pseudo-class.
This patch recognizes that pseudo-class by the GUIDs in those descriptors,
and handles the devices that just use the Zaurus framing.

Another attempt at that...
The attached patch fixes the longstanding problem with USB bcdDevice
numeric ranges incorrectly converted into patterns for MODULE_ALIAS
generation. Previously it put both the lower and the upper limits into
the pattern, dlXdhY, making it impossible to fnmatch against except for
a few special cases, like dl*dh* or dlXdhX.
The patch makes it generate multiple MODULE_ALIAS lines covering the
whole range with fnmatch-able patterns. E.g. for a range between 0x0001
and 0x8345 it gives the following patterns:
000[1-9]
00[1-9]*
0[1-9]*
[1-7]*
8[0-2]*
83[0-3]*
834[0-5]
Since bcdDevice is 2 bytes wide = 4 digits in hex representation, the
max no. of patters is 2 * 4 - 1 = 7.
The values are BCD (binary-coded decimals) and not hex, so patterns
using a dash seem to be safe regardless of locale collation order.
The patch changes bcdDevice part of the alias from dlXdhY to dZ, but
this shouldn't have big compatibility issues because fnmatch()-based
modprobing hasn't yet been widely used. Besides, the most common (and
almost the only working) case of dl*dh* becomes d* and thus continues to
work.
The patch is against 2.6.12-rc2, applies to -mm3 with an offset. The
matching patch to fix the MODALIAS environment variable now generated by
the usb hotplug function follows.
