* mac80211: Add support for connection quality monitoringJuuso Oikarinen2010-03-24
| | | | | | | | | | | | | | | Add support for the set_cqm_config op. This op function configures the requested connection quality monitor rssi threshold and rssi hysteresis values to the hardware if the hardware supports IEEE80211_HW_SUPPORTS_CQM. For unsupported hardware, currently -EOPNOTSUPP is returned, so the mac80211 is currently not doing connection quality monitoring on the host. This could be added later, if needed.

* cfg80211: Add connection quality monitoring support to nl80211Juuso Oikarinen2010-03-24
| | | | | | | | | | | | | | | | | | | | | | | Add support for basic configuration of a connection quality monitoring to the nl80211 interface, and basic support for notifying about triggered monitoring events. Via this interface a user-space connection manager may configure and receive pre-warning events of deteriorating WLAN connection quality, and start preparing for roaming in advance, before the connection is already lost. An example usage of such a trigger is starting scanning for nearby AP's in an attempt to find one with better connection quality, and associate to it before the connection characteristics of the existing connection become too bad or the association is even lost, leading in a prolonged delay in connectivity. The interface currently supports only RSSI, but it could be later extended to include other parameters, such as signal-to-noise ratio, if need for that arises.

* mac80211: Add support for connection monitor in hardwareJuuso Oikarinen2010-03-23
| | | | | | | | | | | | | | | | | | | This patch is based on a RFC patch by Kalle Valo. The wl1271 has a feature which handles the connection monitor logic in hardware, basically sending periodically nullfunc frames and reporting to the host if AP is lost, after attempting to recover by sending probe-requests to the AP. Add support to mac80211 by adding a new flag IEEE80211_HW_CONNECTION_MONITOR which prevents conn_mon_timer from triggering during idle periods, and prevents sending probe-requests to the AP if beacon-loss is indicated by the hardware.

* mac80211: optimize tx status processingFelix Fietkau2010-03-15
| | | | | | | | | | | When a cooked monitor interface is active, ieee80211_tx_status() generates a radiotap header for every single frame, even if it wasn't injected and thus won't be sent to a monitor interface.

* mac80211: give warning if building w/out rate ctrl algorithmAndres Salomon2010-03-10
| | | | | | | | | | | | | | | | | I discovered that if EMBEDDED=y, one can accidentally build a mac80211 stack and drivers w/ no rate control algorithm. For drivers like RTL8187 that don't supply their own RC algorithms, this will cause ieee80211_register_hw to fail (making the driver unusable). This will tell kconfig to provide a warning if no rate control algorithms have been selected. That'll at least warn the user; users that know that their drivers supply a rate control algorithm can safely ignore the warning, and those who don't know (or who expect to be using multiple drivers) can select a default RC algorithm.

* mac80211: Improve software scan timingHelmut Schaa2010-03-09
| | | | | | | | | | | | | | | | | The current software scan implemenation in mac80211 returns to the operating channel after each scanned channel. However, in some situations (e.g. no traffic) it would be nicer to scan a few channels in a row to speed up the scan itself. Hence, after scanning a channel, check if we have queued up any tx frames and return to the operating channel in that case. Unfortunately we don't know if the AP has buffered any frames for us. Hence, scan only as many channels in a row as the pm_qos latency and the negotiated listen interval allows us to. Signed-off-by: Helmut Schaa <helmut.schaa@googlemail.com> Signed-off-by: John W.

* mac80211: Fix HT rate control configurationSujith2010-03-03
| | | | | | | | | | | | | | | | | Handling HT configuration changes involved setting the channel with the new HT parameters and then issuing a rate_update() notification to the driver. This behavior changed after the off-channel changes. Now, the channel is not updated with the new HT params in enable_ht() - instead, it is now done when the scan work terminates. This results in the driver depending on stale information, defaulting to non-HT mode always. Fix this by passing the new channel type to the driver.

* mac80211: Fix reassociation processing (within ESS roaming)Jouni Malinen2010-03-02
| | | | | | | | | | | | | | | | | | Commit e1dd33f60ced091114e4aacf141e0d03b88d3e13 changed cfg80211 to allow association commands while in associated state to enable support for roaming within an ESS. However, this was not enough to resolve all cases with mac80211 which needs some additional handling of the reassociation case to clear internal state with the BSS that was in use previously. This patch makes ieee80211_mgd_assoc() accept a valid reassociation command and clean the association state with the previous BSS. This fixes roaming between BSSes in an ESS when using wpa_supplicant with -Dnl80211. Signed-off-by: Jouni Malinen <j@w1.fi> Cc: stable@kernel.org Signed-off-by: John W.

The elasticity setting does not take effect until the next new multicast group is added. At which point it is checked and if after rehashing it still can't be satisfied then snooping will be disabled. The max setting on the other hand takes effect immediately. It must be a power of two and cannot be set to a value less than the current number of multicast group entries. This is the only way to shrink the multicast hash.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows the user to disable IGMP snooping completely through a sysfs toggle. It also allows the user to reenable snooping when it has been automatically disabled due to hash collisions. If the collisions have not been resolved however the system will refuse to reenable snooping. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

A port with a multicast router will receive all multicast traffic. The value 0 disables it completely. The default is 1 which lets the system automatically detect the presence of routers (currently this is limited to picking up queries), and 2 means that the port will always receive all multicast traffic.

We forward multicast traffic to a set of ports plus all multicast router ports. In order to avoid duplications among these two sets of ports, we order all ports by the numeric value of their pointers. The two lists are then walked in lock-step to eliminate duplicates.

So this patch should be a no-op as far as the bridge's external behaviour is concerned. All the new code and data is controlled by the Kconfig option BRIDGE_IGMP_SNOOPING. A run-time toggle is also available. The multicast switching is done using an hash table that is lockless on the read-side through RCU. On the write-side the new multicast_lock is used for all operations. The hash table supports dynamic growth/rehashing. The hash table will be rehashed if any chain length exceeds a preset limit. If rehashing does not reduce the maximum chain length then snooping will be disabled. These features may be added in future (in no particular order): * IGMPv3 source support * Non-querier router detection * IPv6 Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.
