Adds support for extended window size (EWS) config option. We enable EWS feature in L2CAP Info RSP when hs enabled. EWS option is included in L2CAP Config Req if tx_win (which is set via socket) bigger then standard default value (63) && hs enabled && remote side supports EWS feature. Using EWS selects extended control field in L2CAP. Code partly based on Qualcomm and Atheros patches sent upstream a year ago.

2011-10-03mac80211: Send nullfunc frames at lower rate during connection monitorRajkumar Manoharan1-0/+4
Recently mac80211 was changed to use nullfunc instead of probe request for connection monitoring for tx ack status reporting hardwares. Sometimes in congested network, STA got disconnected quickly after the association. It was observered that the rate control was not adopted to environment due to minimal transmission. As the nullfunc are used for monitoring purpose, these frames should not be sacrificed for rate control updation. So it is better to send the monitoring null func frames at minimum rate that could help to retain the connection. Signed-off-by: Rajkumar Manoharan <rmanohar@qca.qualcomm.com> Signed-off-by: John W.

2011-09-30mac80211: allow out-of-band EOSP notificationJohannes Berg1-2/+22
iwlwifi has a separate EOSP notification from the device, and to make use of that properly it needs to be passed to mac80211. To be able to mix with tx_status_irqsafe and rx_irqsafe it also needs to be an "_irqsafe" version in the sense that it goes through the tasklet, the actual flag clearing would be IRQ-safe but doing it directly would cause reordering issues. This is needed in the case of a P2P GO going into an absence period without transmitting any frames that should be driver-released as in this case there's no other way to inform mac80211 that the service period ended. Note that for drivers that don't use the _irqsafe functions another version of this function will be required. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-09-30mac80211: explicitly notify drivers of frame releaseJohannes Berg1-0/+17
iwlwifi needs to know the number of frames that are going to be sent to a station while it is asleep so it can properly handle the uCode blocking of that station. Before uAPSD, we got by by telling the device that a single frame was going to be released whenever we encountered IEEE80211_TX_CTL_POLL_RESPONSE. With uAPSD, however, that is no longer possible since there could be more than a single frame. To support this model, add a new callback to notify drivers when frames are going to be released.

2011-09-30mac80211: reply only once to each PS-pollJohannes Berg1-1/+8
If a PS-poll frame is retried (but was received) there is no way to detect that since it has no sequence number. As a consequence, the standard asks us to not react to PS-poll frames until the response to one made it out (was ACKed or lost). Implement this by using the WLAN_STA_SP flags to also indicate a PS-Poll "service period" and the IEEE80211_TX_STATUS_EOSP flag for the response packet to indicate the end of the "SP" as usual. We could use separate flags, but that will most likely completely confuse drivers, and while the standard doesn't exclude simultaneously polling using uAPSD and PS-Poll, doing that seems quite problematic.

2011-09-30mac80211: implement uAPSDJohannes Berg1-7/+17
Add uAPSD support to mac80211. This is probably not possible with all devices, so advertising it with the cfg80211 flag will be left up to drivers that want it. Due to my previous patches it is now a fairly straight-forward extension. Drivers need to have accurate TX status reporting for the EOSP frame. For drivers that buffer themselves, the provided APIs allow releasing the right number of frames, but then drivers need to set EOSP and more-data themselves. This is documented in more detail in the new code itself. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-09-30mac80211: allow releasing driver-buffered framesJohannes Berg1-0/+31
If there are frames for a station buffered in the driver, mac80211 announces those in the TIM IE but there's no way to release them. Add new API to release such frames and use it when the station polls for a frame. Since the API will soon also be used for uAPSD it is easily extensible. Note that before this change drivers announcing driver-buffered frames in the TIM bit actually will respond to a PS-Poll with a potentially lower priority frame (if there are any frames buffered in mac80211), after this patch a driver that hasn't been changed will no longer respond at all. This only affects ath9k, which will need to be fixed to implement the new API. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-09-30mac80211: split PS buffers into ACsJohannes Berg1-0/+1
For uAPSD support we'll need to have per-AC PS buffers. As this is a major undertaking, split the buffers before really adding support for uAPSD. This already makes some reference to the uapsd_queues variable, but for now that will never be non-zero. Since book-keeping is complicated, also change the logic for keeping a maximum of frames only and allow 64 frames per AC (up from 128 for a station).

2011-09-30mac80211: let drivers inform it about per TID buffered framesJohannes Berg1-6/+24
For uAPSD implementation, it is necessary to know on which ACs frames are buffered. mac80211 obviously knows about the frames it has buffered itself, but with aggregation many drivers buffer frames. Thus, mac80211 needs to be informed about this. For now, since we don't have APSD in any form, this will unconditionally set the TIM bit for the station but later with uAPSD only some ACs might cause the TIM bit to be set. ath9k is the only driver using this API and I only modify it in the most basic way, it won't be able to implement uAPSD with this yet. But it can't do that anyway since there's no way to selectively release frames to the peer yet. Since drivers will buffer frames per TID, let them inform mac80211 on a per TID basis, mac80211 will then sort out the AC mapping itself.

2011-09-30cfg80211/mac80211: apply station uAPSD parameters selectivelyJohannes Berg1-0/+12
Currently, when hostapd sets the station as authorized we also overwrite its uAPSD parameter. This obviously leads to buggy behaviour (later, with my patches that actually add uAPSD support). To fix this, only apply those parameters if they were actually set in nl80211, and to achieve that add a bitmap of things to apply.

Since commit 7361c36c5224 (af_unix: Allow credentials to work across user and pid namespaces) af_unix performance dropped a lot.

2011-09-27tcp: ECN blackhole should not force quickack modeEric Dumazet1-0/+1
While playing with a new ADSL box at home, I discovered that ECN blackhole can trigger suboptimal quickack mode on linux : We send one ACK for each incoming data frame, without any delay and eventual piggyback. This is because TCP_ECN_check_ce() considers that if no ECT is seen on a segment, this is because this segment was a retransmit. Refine this heuristic and apply it only if we seen ECT in a previous segment, to detect ECN blackhole at IP level.

2011-09-21Bluetooth: Add mgmt events for blacklistingAntti Julku2-0/+12
Add management interface events for blocking/unblocking a device. Sender of the block device command gets cmd complete and other mgmt sockets get the event. Event is also sent to mgmt sockets when blocking is done with ioctl, e.g when blocking a device with hciconfig. This makes it possible for bluetoothd to track status of blocked devices when a third party block or unblocks a device. Event sending is handled in mgmt_device_blocked function which gets called from hci_blacklist_add in hci_core.c. A pending command is added in mgmt_block_device, so that it can found when sending the event - the event is not sent to the socket from which the pending command came. Locks were moved out from hci_core.c to hci_sock.c and mgmt.c, because locking is needed also for mgmt_pending_add in mgmt.c.
