* mac80211: free up 2 bytes in skb->cbFelix Fietkau2008-10-06

* rfkill: update LEDs for all state changesHenrique de Moraes Holschuh2008-10-06
| | | | | | | | | | | | | | | | | | The LED state was not being updated by rfkill_force_state(), which will cause regressions in wireless drivers that had old-style rfkill support and are updated to use rfkill_force_state(). The LED state was not being updated when a change was detected through the rfkill->get_state() hook, either. Move the LED trigger update calls into notify_rfkill_state_change(), where it should have been in the first place. This takes care of both issues above.

* mac80211: remove redundant check in ieee80211_master_start_xmit ↵Rami Rosen2008-10-06
| | | | | | | | | | | | | | | | | | (net/mac80211/tx.c) - This patch (against the linux-wireless-next git tree) removes a redundant check in ieee80211_master_start_xmit (net/mac80211/tx.c) and adjust indentation in this method accordingly. In this method, there is no need to call again the ieee80211_is_data() method; this is checked immediately before, in the "if" command (we will not enter this block unless ieee80211_is_data() is true, so that the "and" (&&) condition in that "if" command will be fullfilled ).

| | | | | | | | | | | qdisc->requeue was planned to universally replace all requeuing code, but at the top level we never requeue more than one skb, so qdisc-> gso_skb is enough for this. qdisc->requeue would be used on the lower levels only for one level deep requeuing (like in sch_hfsc) after finishing all the changes.

* sctp: Fix to start T5-shutdown-guard timer while enter SHUTDOWN-SENT stateWei Yongjun2008-10-01
| | | | | | | | | | | | | | | | | | | | | | RFC 4960: Section 9.2 The sender of the SHUTDOWN MAY also start an overall guard timer 'T5-shutdown-guard' to bound the overall time for the shutdown sequence. At the expiration of this timer, the sender SHOULD abort the association by sending an ABORT chunk. If the 'T5-shutdown- guard' timer is used, it SHOULD be set to the recommended value of 5 times 'RTO.Max'. The timer 'T5-shutdown-guard' is used to counter the overall time for shutdown sequence, and it's start by the sender of the SHUTDOWN. So timer 'T5-shutdown-guard' should be start when we send the first SHUTDOWN chunk and enter the SHUTDOWN-SENT state, not start when we receipt of the SHUTDOWN primitive and enter SHUTDOWN-PENDING state. If 'T5-shutdown-guard' timer is start at SHUTDOWN-PENDING state, the association may be ABORT while data is still transmitting.

* sctp: try harder to figure out address family when checking wildcardsVlad Yasevich2008-10-01
| | | | | | | | | | | sctp_is_any() function that is used to check for wildcard addresses only looks at the address itself to determine the address family. This function is used in the API to check the address passed in from the user. If the user simply zerroes out the sockaddr_storage and pass that in, we'll end up failing. So, let's try harder to determine the address family by also checking the socket if it's possible. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com>

* sctp: Retransmit list is ineligable for missing indicationsVlad Yasevich2008-10-01
| | | | | | | | | | Chunks placed on the retransmit list are marked as inelegible for fast retrasnmission. Since missing indications determine when fast reransmission is done, there is not point in calling sctp_mark_missing() on the retransmit list since those chunks will not be marked.

* udp: Export UDP socket lookup functionKOVACS Krisztian2008-10-01

* tcp: Port redirection support for TCPKOVACS Krisztian2008-10-01
| | | | | | | | | | | | | | | Current TCP code relies on the local port of the listening socket being the same as the destination address of the incoming connection. Port redirection used by many transparent proxying techniques obviously breaks this, so we have to store the original destination port address. This patch extends struct inet_request_sock and stores the incoming destination port value there. It also modifies the handshake code to use that value as the source port when sending reply packets.

* ipv4: Make Netfilter's ip_route_me_harder() non-local address compatibleKOVACS Krisztian2008-10-01
| | | | | | | | | | | Netfilter's ip_route_me_harder() tries to re-route packets either generated or re-routed by Netfilter. This patch changes ip_route_me_harder() to handle packets from non-locally-bound sockets with IP_TRANSPARENT set as local and to set the appropriate flowi flags when re-doing the routing lookup.

* tcp: Handle TCP SYN+ACK/ACK/RST transparencyKOVACS Krisztian2008-10-01
| | | | | | | | | | | | | | The TCP stack sends out SYN+ACK/ACK/RST reply packets in response to incoming packets. The non-local source address check on output bites us again, as replies for transparently redirected traffic won't have a chance to leave the node. This patch selectively sets the FLOWI_FLAG_ANYSRC flag when doing the route lookup for those replies. Transparent replies are enabled if the listening socket has the transparent socket flag set.

* ipv4: Make inet_sock.h independent of route.hKOVACS Krisztian2008-10-01

* ipv4: Allow binding to non-local addresses if IP_TRANSPARENT is setTóth László Attila2008-10-01

* ipv4: Implement IP_TRANSPARENT socket optionKOVACS Krisztian2008-10-01
| | | | | | | | | This patch introduces the IP_TRANSPARENT socket option: enabling that will make the IPv4 routing omit the non-local source address check on output.

* ipv4: Loosen source address check on IPv4 outputJulian Anastasov2008-10-01
| | | | | | | | | | | | | | ip_route_output() contains a check to make sure that no flows with non-local source IP addresses are routed. This obviously makes using such addresses impossible. This patch introduces a flowi flag which makes omitting this check possible. The new flag provides a way of handling transparent and non-transparent connections differently.

* ipsec: Put dumpers on the dump listHerbert Xu2008-10-01
| | | | | | | | | | | | | | | | | | | | | | | Herbert Xu came up with the idea and the original patch to make xfrm_state dump list contain also dumpers: As it is we go to extraordinary lengths to ensure that states don't go away while dumpers go to sleep. It's much easier if we just put the dumpers themselves on the list since they can't go away while they're going. I've also changed the order of addition on new states to prevent a never-ending dump. Timo Teräs improved the patch to apply cleanly to latest tree, modified iteration code to be more readable by using a common struct for entries in the list, implemented the same idea for xfrm_policy dumping and moved the af_key specific "last" entry caching to af_key.

| * sctp: Fix kernel panic while process protocol violation parameterWei Yongjun2008-09-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since call to function sctp_sf_abort_violation() need paramter 'arg' with 'struct sctp_chunk' type, it will read the chunk type and chunk length from the chunk_hdr member of chunk. But call to sctp_sf_violation_paramlen() always with 'struct sctp_paramhdr' type's parameter, it will be passed to sctp_sf_abort_violation(). This may cause kernel panic. sctp_sf_violation_paramlen() |-- sctp_sf_abort_violation() |-- sctp_make_abort_violation() This patch fixed this problem. This patch also fix two place which called sctp_sf_violation_paramlen() with wrong paramter type.
