[NETFILTER]: Introduce NF_INET_ hook values
It always evaluates to NF_INET_POST_ROUTING.
Signed-off-by: David S. Miller <davem@davemloft.net>

The IPv4 and IPv6 hook values are identical, yet some code tries to figure
out the "correct" value by looking at the address family. Introduce NF_INET_*
values for both IPv4 and IPv6. The old values are kept in a #ifndef __KERNEL__
section for userspace compatibility.

This patch adds support for async resumptions on input. To do so, the
transform would return -EINPROGRESS and subsequently invoke the
function xfrm_input_resume to resume processing.

The nhoff field isn't actually necessary in xfrm_input. For tunnel
mode transforms we now throw away the output IP header so it makes no
sense to fill in the nexthdr field. For transport mode we can now let
the function transport_finish do the setting and it knows where the
nexthdr field is.
The only other thing that needs the nexthdr field to be set is the
header extraction code. However, we can simply move the protocol
extraction out of the generic header extraction.
We want to minimise the amount of info we have to carry around between
transforms as this simplifies the resumption process for async crypto.

Currently x->lastused is u64 which means that it cannot be
read/written atomically on all architectures. David Miller observed
that the value stored in it is only an unsigned long which is always
atomic.
So based on his suggestion this patch changes the internal
representation from u64 to unsigned long while the user-interface
still refers to it as u64.

As part of the work on asynchronous cryptographic operations, we need
to be able to resume from the spot where they occur. As such, it
helps if we isolate them to one spot.
This patch moves most of the remaining family-specific processing into
the common input code.

Most callers of the LOCAL_OUT chain will set the IP packet length
before doing so. They also share the same output function dst_output.
This patch creates a new function called ip6_local_out which does all
of that and converts the appropriate users over to it.
Apart from removing duplicate code, it will also help in merging the
IPsec output path.

With inter-family transforms the inner mode differs from the outer
mode. Attempting to handle both sides from the same function means
that it needs to handle both IPv4 and IPv6 which creates duplication
and confusion.
This patch separates the two parts on the input path so that each
function deals with one family only.
In particular, the functions xfrm4_extract_inut/xfrm6_extract_inut
moves the pertinent fields from the IPv4/IPv6 IP headers into a
neutral format stored in skb->cb. This is then used by the inner mode
input functions to modify the inner IP header. In this way the input
function no longer has to know about the outer address family.

In particular, the functions xfrm4_extract_output/xfrm6_extract_output

output functions to write the outer IP header. In this way the output
function no longer has to know about the inner address family.
Since the extract functions are only called by tunnel modes (the only
modes that can support inter-family transforms), I've also moved the
xfrm*_tunnel_check_size calls into them. This allows the correct ICMP
message to be sent as opposed to now where you might call icmp_send
with an IPv6 packet and vice versa.

Half of the code in xfrm4_bundle_create and xfrm6_bundle_create are
common. This patch extracts that logic and puts it into
xfrm_bundle_create. The rest of it are then accessed through afinfo.
As a result this fixes the problem with inter-family transforms where
we treat every xfrm dst in the bundle as if it belongs to the top
family.
This patch also fixes a long-standing error-path bug where we may free
the xfrm states twice.

This patch moves the flow construction from the callers of
xfrm_dst_lookup into that function. It also changes xfrm_dst_lookup
so that it takes an xfrm state as its argument instead of explicit
addresses.
This removes any address-specific logic from the callers of
xfrm_dst_lookup which is needed to correctly support inter-family
transforms.

We have a number of copies of dst_discard scattered around the place
which all do the same thing, namely free a packet on the input or
output paths.
This patch deletes all of them except dst_discard and points all the
users to it.
The only non-trivial bit is decnet where it returns an error.
However, conceptually this is identical to the blackhole functions
used in IPv4 and IPv6 which do not return errors. So they should
either all return errors or all return zero. For now I've stuck with
the majority and picked zero as the return value.
It doesn't really matter in practice since few if any driver would
react differently depending on a zero return value or NET_RX_DROP.

The dst member nfheader_len is only used by IPv6. It's also currently
creating a rather ugly alignment hole in struct dst. Therefore this patch
moves it from there into struct rt6_info.

Samsung USB remotes (0419:0001) are rejected by kernel 2.6.23, because the
report descriptor from the remote contains a 48 bit HID report field. HID 1.11
states: Fields may span at most 4 bytes.
This patch, based on 2.6.23, fixes this by modifying the internal report
descriptor in hid-quirks.c. Additional user space support (e.g. LIRC) is
required to fetch the information from the hiddev interface.
The burden to reconstruct the data is moved into userspace (lirc through hiddev).
There is no need to set HID_QUIRK_HIDDEV quirk, as the device has also output
applications, which trigger the creation of hiddev device automatically.

BTC 8193 keyboard handles its scrollwheel in very non-standard way.
It produces two non-standard usages for scrolling up and down, in
both cases with postive value equaling to 1. We handle this by temporary
mapping, which we then catch in quirk event handler, and remap to
negative HWHEEL even in order to introduce correct behavior.
Also the button requires special mapping, as it triggers standard-violating
usage code.

Currently, the handling of mapping between hid and input for devices
that don't conform to HUT 1.12 specification is very messy -- no per-device
handling, no blacklists, conditions on idVendor and idProduct placed
all over the code.
This patch moves all the device-specific input mapping to a separate
file, and introduces a blacklist-style handling for non-standard
device-specific mappings.

Genius KB-29E has broken report descriptor, which causes some of the
Consumer usages to appear incorrectly as Button usages. We fix it by
fixing the report descriptor before it is being parsed.
Also a few of the keys violate the HUT standard, so they need a special

If an DMA channel was active at suspend, then ensure that
it is correctly reconfigured when the system resumes.
Note, the previous policy was for each driver to handle their
own reconfiguration on resume. The policy has been changed to
make the individual driver's job easier.

The current S3C24XX DMA code does not allow for an peripheral
that has one channel for RX and another for TX.
This patch adds a per-cpu dma operation to select the transmit
or receive channel, and adds support to the S3C2412 for the
seperate DMA channels for TX and RX.
