* dccp ccid-2: Remove old infrastructureGerrit Renker2010-11-152-265/+0
| | | | | | | | | This removes * functions for which updates have been provided in the preceding patches and * the @av_vec_len field - it is no longer necessary since the buffer length is now always computed dynamically. Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk>
* dccp ccid-2: Schedule Sync as out-of-band mechanismGerrit Renker2010-11-153-4/+37
| | | | | | | | | | | | | | | | | | | | | The problem with Ack Vectors is that i) their length is variable and can in principle grow quite large, ii) it is hard to predict exactly how large they will be. Due to the second point it seems not a good idea to reduce the MPS; in particular when on average there is enough room for the Ack Vector and an increase in length is momentarily due to some burst loss, after which the Ack Vector returns to its normal/average length. The solution taken by this patch is to subtract a minimum-expected Ack Vector length from the MPS, and to defer any larger Ack Vectors onto a separate Sync - but only if indeed there is no space left on the skb. This patch provides the infrastructure to schedule Sync-packets for transporting (urgent) out-of-band data. Its signalling is quicker than scheduling an Ack, since it does not need to wait for new application data. Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk>
* dccp ccid-2: Consolidate Ack-Vector processing within main DCCP moduleGerrit Renker2010-11-151-22/+9
| | | | | | | | | | | | This aggregates Ack Vector processing (handling input and clearing old state) into one function, for the following reasons and benefits: * all Ack Vector-specific processing is now in one place; * duplicated code is removed; * ensuring sanity: from an Ack Vector point of view, it is better to clear the old state first before entering new state; * Ack Event handling happens mostly within the CCIDs, not the main DCCP module.

* dccp ccid-2: Update code for the Ack Vector input/registration routineGerrit Renker2010-11-152-0/+154
| | | | | | | | | This patch updates the code which registers new packets as received, using the new circular buffer interface. It contributes a new algorithm which * supports both tail/head pointers and buffer wrap-around and * deals with overflow (head/tail move in lock-step).

* dccp ccid-2: Algorithm to update buffer stateGerrit Renker2010-11-154-6/+93
| | | | | | | | | | | | | | | | | | | This provides a routine to consistently update the buffer state when the peer acknowledges receipt of Ack Vectors; updating state in the list of Ack Vectors as well as in the circular buffer. While based on RFC 4340, several additional (and necessary) precautions were added to protect the consistency of the buffer state. These additions are essential, since analysis and experience showed that the basic algorithm was insufficient for this task (which lead to problems that were hard to debug). The algorithm now * deals with HC-sender acknowledging to HC-receiver and vice versa, * keeps track of the last unacknowledged but received seqno in tail_ackno, * has special cases to reset the overflow condition when appropriate, * is protected against receiving older information (would mess up buffer state).

The intent is that when the interface comes back up the address will be usable again. However, this doesn't actually work, because the system stops listening on the corresponding solicited-node multicast address, so the address cannot respond to neighbor solicitations and thus receive traffic. Also, the code notifies the rest of the system that the address is being deleted (e.g, RTM_DELADDR), even though it is not. Fix it so that none of this state is updated if the address is being kept on the interface. Tested: Added a statically configured IPv6 address to an interface, started ping, brought link down, brought link up again. When link came up ping kept on going and "ip -6 maddr" showed that the host was still subscribed to there Signed-off-by: Lorenzo Colitti <lorenzo@google.com> Signed-off-by: David S.

C will evalutate == before =. Which means ret is getting set to the bool result, rather than the return value of the function call. The code says if (ret = function() == 1) when it meant to say: if ((ret = function()) == 1) Normally the compiler would warn, but it doesn't notice it because its a actually complex conditional and so the wrong code is wrapped in an explict set of () [exactly what the compiler wants you to do if this was intentional]. Fixing this means that errors when netfilter denies a packet get propagated back up the stack rather than lost.

| | | * | Bluetooth: Fix non-SSP auth request for HIGH security level socketsJohan Hedberg2010-11-091-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When initiating dedicated bonding a L2CAP raw socket with HIGH security level is used. The kernel is supposed to trigger the authentication request in this case but this doesn't happen currently for non-SSP (pre-2.1) devices. The reason is that the authentication request happens in the remote extended features callback which never gets called for non-SSP devices. This patch fixes the issue by requesting also authentiation in the (normal) remote features callback in the case of non-SSP devices. This rule is applied only for HIGH security level which might at first seem unintuitive since on the server socket side MEDIUM is already enough for authentication. However, for the clients we really want to prefer the server side to decide the authentication requrement in most cases, and since most client sockets use MEDIUM it's better to be avoided on the kernel side for these sockets. The important socket to request it for is the dedicated bonding one and that socket uses HIGH security level. The patch is based on the initial investigation and patch proposal from Andrei Emeltchenko <endrei.emeltchenko@nokia.com>.

This bit is write only, but the driver does a read-modify-write on AR_WA without setting bit 22 in ar9002_hw_configpcipowersave() during radio disable. This causes surprise removal of hw. It can never recover from this state and the hw will become usable only after a power on/off cycle, and sometimes only during a cold reboot. This issue can be triggered by doing frequent roaming with the simple/test-roam script available from the wifi-test project [1] when roaming between APs quickly. When roaming there is a is a high possibility that the device being put into idle (radio disable) state by mac80211 during AUTH->ASSOC.

When ieee80211_offchannel_return is invoked as part of cancelling the scan, it doesn't bother unsetting the SDATA_STATE_OFFCHANNEL bit because it sees that the interface is down. Normally this doesn't matter because when the client STA interface is brought back up, it will probably issue a scan. But in some cases (e.g., the user changes the interface type while it is down), the SDATA_STATE_OFFCHANNEL bit will remain set. This prevents the interface queues from being started. So we cancel the scan before unsetting the SDATA_STATE_RUNNING bit. Signed-off-by: Brian Cavagnolo <brian@cozybit.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
