* ipv4: rename ip_options_echo to __ip_options_echo()Eric Dumazet2014-09-283-11/+13
| | | | | | | | | | ip_options_echo() assumes struct ip_options is provided in &IPCB(skb)->opt Lets break this assumption, but provide a helper to not change all call points. ip_send_unicast_reply() gets a new struct ip_options pointer.

* net: optimise inet_proto_csum_replace4()LEROY Christophe2014-09-261-7/+5
| | | | | | | | | | | | | | | | | csum_partial() is a generic function which is not optimised for small fixed length calculations, and its use requires to store "from" and "to" values in memory while we already have them available in registers. This also has impact, especially on RISC processors. In the same spirit as the change done by Eric Dumazet on csum_replace2(), this patch rewrites inet_proto_csum_replace4() taking into account RFC1624. I spotted during a NATted tcp transfert that csum_partial() is one of top 5 consuming functions (around 8%), and the second user of csum_partial() is inet_proto_csum_replace4().

* net: introduce __skb_header_release()Eric Dumazet2014-09-263-9/+9
| | | | | | | | | | | | | | | While profiling TCP stack, I noticed one useless atomic operation in tcp_sendmsg(), caused by skb_header_release(). It turns out all current skb_header_release() users have a fresh skb, that no other user can see, so we can avoid one atomic operation. Introduce __skb_header_release() to clearly document this. This gave me a 1.5 % improvement on TCP_RR workload. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Linville says: ==================== pull request: wireless-next 2014-09-22 Please pull this batch of updates intended for the 3.18 stream... For the mac80211 bits, Johannes says: "This time, I have some rate minstrel improvements, support for a very small feature from CCX that Steinar reverse-engineered, dynamic ACK timeout support, a number of changes for TDLS, early support for radio resource measurement and many fixes. Also, I'm changing a number of places to clear key memory when it's freed and Intel claims copyright for code they developed." For the bluetooth bits, Johan says: "Here are some more patches intended for 3.18. Most of them are cleanups or fixes for SMP. The only exception is a fix for BR/EDR L2CAP fixed channels which should now work better together with the L2CAP information request procedure." For the iwlwifi bits, Emmanuel says: "I fix here dvm which was broken by my last pull request. Arik continues to work on TDLS and Luca solved a few issues in CT-Kill. Eyal keeps digging into rate scaling code, more to come soon. Besides this, nothing really special here." Beyond that, there are the usual big batches of updates to ath9k, b43, mwifiex, and wil6210 as well as a handful of other bits here and there. Also, rtlwifi gets some btcoexist attention from Larry. Please let me know if there are problems! ==================== Had to adjust the wil6210 code to comply with Joe Perches's recent change in net-next to make the netdev_*() routines return void instead of 'int'.

| | * Bluetooth: Fix re-setting RPA as expired when deferring updateJohan Hedberg2014-09-121-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hci_update_random_address will clear the RPA_EXPIRED flag and proceed with setting a new one if the flag was set. However, the set_random_addr() function that is called may choose to defer the update to a later moment. In such a case the flag would incorrectly remain unset unless set_random_addr() re-sets it.

| | * Bluetooth: Fix L2CAP information request handling for fixed channelsJohan Hedberg2014-09-111-20/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Even if we have no connection-oriented channels we should perform the L2CAP Information Request procedures before notifying L2CAP channels of the connection. This is so that the L2CAP channel implementations can perform checks on what the remote side supports (e.g. does it support the fixed channel in question). So far the code has relied on the l2cap_do_start() function to initiate the Information Request, however l2cap_do_start() is used on a per-channel basis and only for connection-oriented channels. This means that if there are no connection-oriented channels on the system we would never start the Information Request procedure. This patch creates a new l2cap_request_info() helper function to initiate the Information Request procedure, and ensures that it is called whenever a BR/EDR connection has been established. The patch also updates fixed channels to be notified of connection readiness only once the Information Request procedure has completed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SMP specification states that we should ignore any unknown bits from the authentication requirement. We already have a define for masking out unknown bits but we haven't used it in all places so far.

However, 802.11h is only defined for 5 GHz, where the need for this is much smaller than on 2.4 GHz. Cisco has their own solution, called DTPC (Dynamic Transmit Power Control). Cisco APs on a controller sometimes but not always send 802.11h; they always send DTPC, even on 2.4 GHz. This patch adds support for parsing and honoring the DTPC IE in addition to the 802.11h element (they do not always contain the same limits, so both must be honored); the format is not documented, but very simple. Tested (on top of wireless.git and on 3.16.1) against a Cisco Aironet 1142 joined to a Cisco 2504 WLC, by setting various transmit power levels for the given access points and observing the results.

| | * cfg80211: avoid duplicate entries on regdomain intersectionEliad Peller2014-09-051-21/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The regdom intersection code simply tries intersecting each rule of the source with each rule of the target. Since the resulting intersections are not observed as a whole, this can result in multiple overlapping/duplicate entries. Make the rule addition a bit more smarter, by looking for rules that can be contained within other rules, and adding only extended ones.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a flag attribute to use in associations, for tagging the target connection as supporting RRM. It is the responsibility of upper layers to set this flag only if both the underlying device, and the target network indeed support RRM. To be used in ASSOCIATE and CONNECT commands.

| | * mac80211: fix offloaded BA session traffic after hw restartMichal Kazior2014-09-035-14/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When starting an offloaded BA session it is unknown what starting sequence number should be used. Using last_seq worked in most cases except after hw restart. When hw restart is requested last_seq is (rightfully so) kept unmodified. This ended up with BA sessions being restarted with an aribtrary BA window values resulting in dropped frames until sequence numbers caught up. Instead of last_seq pick seqno of a first Rxed frame of a given BA session. This fixes stalled traffic after hw restart with offloaded BA sessions (currently only ath10k).
