Fix the checksum feature advertised in device flags. The hardware support
TCP/UDP over IPv4 and TCP/UDP over IPv6 (without IPv6 extension headers).
However, the kernel feature flags do not distinguish IPv6 with/without
extension headers.
Therefore, the driver needs to use NETIF_F_IP_CSUM instead of
NETIF_F_HW_CSUM since the latter includes all IPv6 packets.
A future patch can be created to check for extension headers and perform
software checksum calculation.

This patch fixes a ibmveth bug where bad UDP checksums are being transmitted
when checksum offloading is enabled.
The hypervisor does checksum offloading only on TCP packets, so ibmveth calls
skb_checksum_help() for any other protocol. The bug happens because
the packet is being modified after the DMA map, so we would need a memory
barrier before making the hypervisor call. Reordering the code so that the
DMA map happens after skb_checksum_help() has the additional advantage of
fixing a DMA map leak if skb_checksum_help() where to fail.

dccp_disconnect() can be called due to several reasons:
1. when the connection setup failed (inet_stream_connect());
2. when shutting down (inet_shutdown(), inet_csk_listen_stop());
3. when aborting the connection (dccp_close() with 0 linger time).
In case (1) the write queue is empty. This patch empties the write queue,
if in case (2) or (3) it was not yet empty.
This avoids triggering the write-queue BUG_TRAP in sk_stream_kill_queues()
later on.
It also seems natural to do: when breaking an association, to delete all
packets that were originally intended for the soon-disconnected end (compare
with call to tcp_write_queue_purge in tcp_disconnect()).

This updates the use of the `out_invalid_option' label, which produces a

Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk>
This updates the option-parsing code with regard to RFC 4340, 5.8:
"[..] options with nonsensical lengths (length byte less than two or more
than the remaining space in the options portion of the header) MUST be
ignored, and any option space following an option with nonsensical length
MUST likewise be ignored."
Hence in the following cases erratic options will be ignored:
1. The type byte of a multi-byte option is the last byte of the header
options (i.e. effective option length of 1).
2. The value of the length byte is less than the minimum 2. This has been
changed from previously 3: although no multi-byte option with a length
less than 3 yet exists (cf. table 3 in 5.8), a length of 2 is valid.
(The switch-statement in dccp_parse has further per-option length checks.)
3. The option length exceeds the length of the remaining option space.

RFC4340 states that if a packet is received with an option error (such as a
Mandatory Option as the last byte of the option list), the endpoint should
repond with a Reset.
In the LISTEN and RESPOND states, the endpoint correctly reponds with Reset,
while in the REQUEST/OPEN states, packets with option errors are just ignored.
The packet sequence is as follows:
Case 1:
Endpoint A Endpoint B
(CLOSED) (CLOSED)
<---------------- REQUEST
RESPONSE -----------------> (*1)
(with invalid option)
<---------------- RESET
(with Reset Code 5, "Option Error")
(*1) currently just ignored, no Reset is sent
Case 2:
Endpoint A Endpoint B
(OPEN) (OPEN)
DATA-ACK -----------------> (*2)
(with invalid option)
<---------------- RESET
(with Reset Code 5, "Option Error")
(*2) currently just ignored, no Reset is sent
This patch fixes the problem, by generating a Reset instead of silently
ignoring option errors.

The association request includes a list of supported data rates.
802.11b: 4 supported rates.
802.11g: 12 (8 + 4) supported rates.
802.11a: 8 supported rates.
The rates tag of the assoc request has room for only 8 rates. In case of
802.11g an extended rate tag is appended. However in net/wireless/mlme.c
an extended (empty) rate tag is also appended if the number of rates is
exact 8. This empty (length=0) extended rates tag causes some APs to
deny association with code 18 (unsupported rates). These APs include my
ZyXEL G-570U, and according to Tomas Winkler som Cisco APs.
'If count == 8' has been used to check for the need for an extended rates
tag. But count would also be equal to 8 if the for loop exited because of
no more supported rates. Therefore a check for count being less than
rates_len would seem more correct.

Previous version was using incorrect union structures for non-AP
interfaces when adding and removing max_ratectrl_rateidx and
force_unicast_rateidx entries. Depending on the vif type, this ended
up in corrupting debugfs entries since the dentries inside different
union structures ended up going being on top of eachother.. As the
end result, debugfs files were being left behind with references to
freed data (instant kernel oops on access) and directories were not
removed properly when unloading mac80211 drivers. This patch fixes
those issues by using only a single union structure based on the vif
type.

The previous code was using IWEVCUSTOM to report IEs from AssocReq and
AssocResp frames into user space. This can easily hit the 256 byte
limit (IW_CUSTOM_MAX) with APs that include number of vendor IEs in
AssocResp. This results in the event message not being sent and dmesg
showing "wlan0 (WE) : Wireless Event too big (366)" type of errors.
Convert mac80211 to use IWEVASSOCREQIE/IWEVASSOCRESPIE to avoid the
issue of being unable to send association IEs as wireless events. These
newer event types use binary encoding and larger maximum size
(IW_GENERIC_IE_MAX = 1024), so the likelyhood of not being able to send
the IEs is much smaller than with IWEVCUSTOM. As an extra benefit, the
code is also quite a bit simpler since there is no need to allocate an
extra buffer for hex encoding.
