2011-02-08Bluetooth: Add send_mode_rsp convenience function for mgmt.cJohan Hedberg
Several management commands have similar responses but they are not always sent asynchronously. To enable synchronous sending (from the managment command handler function) a send_mode_rsp function is added. Signed-off-by: Johan Hedberg <johan.hedberg@nokia.com> Signed-off-by: Gustavo F.

2011-02-08Bluetooth: Add flag to track managment controlled adaptersJohan Hedberg
This patch adds a HCI_MGMT flag to track adapters which are under the control of the management interface. This is needed to make sure that new kernels will work with old user space versions. I.e. behaviour which could break old user space versions (but is needed by the management interface) should not be exhibited when the HCI_MGMT flag is not set.

2011-02-08Bluetooth: Add set_connectable management commandJohan Hedberg
This patch adds a set_connectable command as well as a corresponding event to the management interface. It's mainly useful for setting an adapter as connectable from a non-initialized state as well as setting an already initialized adapter as non-connectable (mostly useful for qualification purposes).

2011-02-08Bluetooth: Implement automatic setup procedure for local adaptersJohan Hedberg
This patch implements automatic initialization of basic information about newly registered Bluetooth adapters. E.g. the address and features are always needed so it makes sense for the kernel to automatically power on adapters and read this information. A new HCI_SETUP flag is added to track this state. In order to not consume unnecessary amounts of power if there isn't a user space available that could switch the adapter back off, a timer is added to do this automatically as long as no Bluetooth user space seems to be present. A new HCI_AUTO_OFF flag is added that user space needs to clear to avoid the automatic power off. Additionally, the management interface index_added event is moved to the end of the HCI_SETUP stage so a user space supporting the managment inteface has all the necessary information available for fetching when it gets notified of a new adapter. The HCI_DEV_REG event is kept in the same place as before since existing HCI raw socket based user space versions depend on seeing the kernels initialization sequence (hci_init_req) to determine when the adapter is ready for use.

2011-02-08Bluetooth: Use non-flushable by default L2CAP data packetsAndrei Emeltchenko
Modification of Nick Pelly <npelly@google.com> patch. With Bluetooth 2.1 ACL packets can be flushable or non-flushable. This commit makes ACL data packets non-flushable by default on compatible chipsets, and adds the BT_FLUSHABLE socket option to explicitly request flushable ACL data packets for a given L2CAP socket. This is useful for A2DP data which can be safely discarded if it can not be delivered within a short time (while other ACL data should not be discarded). Note that making ACL data flushable has no effect unless the automatic flush timeout for that ACL link is changed from its default of 0 (infinite). Default packet types (for compatible chipsets): Frame 34: 13 bytes on wire (104 bits), 13 bytes captured (104 bits) Bluetooth HCI H4 Bluetooth HCI ACL Packet .... 0000 0000 0010 = Connection Handle: 0x0002 ..00 .... .... .... = PB Flag: First Non-automatically Flushable Packet (0) 00.. .... .... .... = BC Flag: Point-To-Point (0) Data Total Length: 8 Bluetooth L2CAP Packet After setting BT_FLUSHABLE (sock.setsockopt(274 /*SOL_BLUETOOTH*/, 8 /* BT_FLUSHABLE */, 1 /* flush */)) Frame 34: 13 bytes on wire (104 bits), 13 bytes captured (104 bits) Bluetooth HCI H4 Bluetooth HCI ACL Packet .... 0000 0000 0010 = Connection Handle: 0x0002 ..10 .... .... .... = PB Flag: First Automatically Flushable Packet (2) 00.. .... .... .... = BC Flag: Point-To-Point (0) Data Total Length: 8 Bluetooth L2CAP Packet Signed-off-by: Andrei Emeltchenko <andrei.emeltchenko@nokia.com> Signed-off-by: Gustavo F.

2011-02-07x25: possible skb leak on bad facilitiesandrew hendry
Originally x25_parse_facilities returned -1 for an error 0 meaning 0 length facilities >0 the length of the facilities parsed. 5ef41308f94dc ("x25: Prevent crashing when parsing bad X.25 facilities") introduced more error checking in x25_parse_facilities however used 0 to indicate bad parsing a6331d6f9a429 ("memory corruption in X.25 facilities parsing") followed this further for DTE facilities, again using 0 for bad parsing. The meaning of 0 got confused in the callers. If the facilities are messed up we can't determine where the data starts. So patch makes all parsing errors return -1 and ensures callers close and don't use the skb further.

2011-02-04mac80211: Optimize scans on current operating channel.Ben Greear
This should decrease un-necessary flushes, on/off channel work, and channel changes in cases where the only scanned channel is the current operating channel. * Removes SCAN_OFF_CHANNEL flag, uses SDATA_STATE_OFFCHANNEL and is-scanning flags instead. * Add helper method to determine if we are currently configured for the operating channel. * Do no blindly go off/on channel in work.c Instead, only call appropriate on/off code when we really need to change channels. Always enable offchannel-ps mode when starting work, and disable it when we are done. * Consolidate ieee80211_offchannel_stop_station and ieee80211_offchannel_stop_beaconing, call it ieee80211_offchannel_stop_vifs instead. * Accept non-beacon frames when scanning on operating channel. * Scan state machine optimized to minimize on/off channel transitions. Also, when going on-channel, go ahead and re-enable beaconing. We're going to be there for 200ms, so seems like some useful beaconing could happen. Always enable offchannel-ps mode when starting software scan, and disable it when we are done. * Grab local->mtx earlier in __ieee80211_scan_completed_finish so that we are protected when calling hw_config(), etc. * Pass probe-responses up the stack if scanning on local channel, so that mlme can take a look.

2011-02-04mac80211: do not restart ps timer during scan or offchannelRajkumar Manoharan
While leaving oper channel, STA informs sleep state to AP to stop sending data. Till sending ack for the nullfunc, AP continues to send the data to STA which restarts ps_timer that is causing unnecessary nullfunc exchange on timer expiry when the STA was already moved to offchannel. So don't restart ps_timer on data reception during scan. This issue was identified by the following warning.

2011-02-04mac80211: fix race between next beacon dtim and ieee80211_get_buffered_bcChristian Lamparter
On review of 'zd1211rw: implement beacon fetching and handling ieee80211_get_buffered_bc()', Christian Lamparter noted that [1]: Since zd_beacon_done also uploads the next beacon so long in advance, there could be an equally long race between the outdated state of the next beacon's DTIM broadcast traffic indicator (802.11-2007 7.3.2.6) which -in your case- was uploaded almost a beacon interval ago and the xmit of ieee80211_get_buffered_bc *now*. The dtim bc/mc bit might be not set, when a mc/bc arrived after the beacon was uploaded, but before the "beacon done event" from the hardware. So, dozing stations don't expect the broadcast traffic and of course, they might miss it completely. It's probably better to fix this in mac80211 (see the attached hack).

2011-02-03mac80211: Add testing functionality for TKIPJouni Malinen
TKIP countermeasures depend on devices being able to detect Michael MIC failures on received frames and for stations to report errors to the AP. In order to test that behavior, it is useful to be able to send out TKIP frames with incorrect Michael MIC. This testing behavior has minimal effect on the TX path, so it can be added to mac80211 for convenient use. The interface for using this functionality is a file in mac80211 netdev debugfs (tkip_mic_test). Writing a MAC address to the file makes mac80211 generate a dummy data frame that will be sent out using invalid Michael MIC value. In AP mode, the address needs to be for one of the associated stations or ff:ff:ff:ff:ff:ff to use a broadcast frame. In station mode, the address can be anything, e.g., the current BSSID. It should be noted that this functionality works correctly only when associated and using TKIP.

2011-02-03cfg80211: Fix power save state after interface type changeJuuso Oikarinen
Currently cfg80211 only configures the PSM state to the driver upon creation of a new virtual interface, but not after interface type change. The mac80211 on the other hand reinitializes its sdata structure every time the interface type is changed, losing the PSM configuration. Hence, if the interface type is changed to, say, ad-hoc and then back to managed, "iw wlan0 get power_save" will claim that PSM is enabled, when in fact on mac80211 level it is not.

I have a netgear WNDR3700 that appears to have an off-by-four bug in how it fills out the hti->control_chan (I configure the AP to channel 11, it reports 15 as control_chan). Poke a message into the kernel logs to give users a clue as to why they are not getting the expected channel-type or rate. Signed-off-by: Ben Greear <greearb@candelatech.com> Signed-off-by: John W.

If we cannot set the channel type, set the channel back to the original. Don't update the driver hardware if nothing actually changed. Signed-off-by: Ben Greear <greearb@candelatech.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

Use sctp_app_lock instead of tcp_app_lock in the SCTP protocol module. This appears to be a typo introduced by the netns changes. Signed-off-by: Simon Horman <horms@verge.net.au> Signed-off-by: Hans Schillstrom <hans.schillstrom@ericsson.com>

2011-02-02sched: CHOKe flow schedulerstephen hemminger
CHOKe ("CHOose and Kill" or "CHOose and Keep") is an alternative packet scheduler based on the Random Exponential Drop (RED) algorithm. The core idea is: For every packet arrival: Calculate Qave if (Qave < minth) Queue the new packet else Select randomly a packet from the queue if (both packets from same flow) then Drop both the packets else if (Qave > maxth) Drop packet else Admit packet with proability p (same as RED) See also: Rong Pan, Balaji Prabhakar, Konstantinos Psounis, "CHOKe: a stateless active queue management scheme for approximating fair bandwidth allocation", Proceeding of INFOCOM'2000, March 2000.

2011-02-02sfq: deadlock in error pathstephen hemminger
The change to allow divisor to be a parameter (in 2.6.38-rc1) commit 817fb15dfd988d8dda916ee04fa506f0c466b9d6 introduced a possible deadlock caught by sparse. The scheduler tree lock was left locked in the case of an incorrect divisor value. Simplest fix is to move test outside of lock which also solves problem of partial update.

2011-02-02ipv4: Fix fib_trie build in some configurations.David S. Miller
If we end up including include/linux/node.h (either explicitly or implicitly) that header has a definition of "structt node" too. So rename the one we use in fib_trie to "rt_trie_node" to avoid the conflict. Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
