2009-11-18b43: Enforce DMA descriptor memory constraintsmaster-2009-11-18Michael Buesch
Enforce all device constraints on the descriptor memory region. There are several constraints on the descriptor memory, as documented in the specification. The current code does not enforce them and/or incorrectly enforces them. Those constraints are: - The address limitations on 30/32bit engines, that also apply to the skbs. - The 4k alignment requirement on 30/32bit engines. - The 8k alignment requirement on 64bit engines.

2009-11-18cfg80211: Allow reassociation in associated stateJouni Malinen
cfg80211 rejects all association requests when in associated state. This prevents clean roaming within an ESS since one would first need to disassociate before being able to request reassociation. Accept the reassociation request and let the old association to be dropped when the new one is completed. This fixes nl80211-based roaming with the current snapshot version of wpa_supplicant (that has code for requesting reassociation explicitly withthe previous BSSID attribute).

2009-11-18mac80211: make software rate control optionalJohannes Berg
Some devices implement the entire rate control in firmware in some way, like wl1271 or like iwlwifi which does some things in software but not a lot. Therefore generic software rate control is rather useless for them and just adds avoidable overhead to the transmit path. It's fairly simple to let drivers indicate that they do not need rate control, but they need to fulfil a number of conditions that we encode in WARN_ONs.

2009-11-18mac80211: use fixed broadcast addressJohannes Berg
The netdev broadcast address cannot change from all-ones so there's no need to use it; we can instead hard-code it. Since we already have an instance in tkip.c, which will be shared if it is marked static const, doing this reduces text size at no data/bss cost. The real motivation for this is, of course, the desire to get rid of almost all uses of netdevs in mac80211 so that auditing their use becomes easier.

2009-11-18mac80211: improve rate handlingJohannes Berg
Some code currently assumes that there's a valid rate pointer even in the HT case, but there can't be. To reduce reliance on that, remove the rate pointer from the RX data struct and pass it where it's needed. Also, for now, in radiotap announce HT frames as having a DYN channel type, and remove their rate from cooked monitor radiotap completely (it isn't present in the regular monitor radiotap either.)

2009-11-18mac80211: reduce the amount of unnecessary traffic on cooked monitor interfacesFelix Fietkau
In order to handle association and authentication in AP mode, hostapd needs access to the tx status info of its own frames through a cooked monitor interface. Without this patch the cooked monitor interfaces also passed on tx status information for packets from other virtual interfaces. This creates a significant performance issue on embedded system. Hostapd tries to work around this by installing a Linux Socket Filter that only captures the frames it's interested in, however data duplication and socket filter matching still uses up enough CPU cycles to be very noticeable on small systems.

2009-11-18iwlwifi: handle unicast PS bufferingJohannes Berg
Using the new mac80211 functionality, this makes iwlwifi handle unicast PS buffering correctly. The device works like this: * when a station goes to sleep, the microcode notices this and marks the station as asleep * when the station is marked asleep, the microcode refuses to transmit to the station and rejects all frames queued to it with the failure status code TX_STATUS_FAIL_DEST_PS (a previous patch handled this correctly) * when we need to send frames to the station _although_ it is asleep, we need to tell the ucode how many, and this is asynchronous with sending so we cannot just send the frames, we need to wait for all other frames to be flushed, and then update the counter before sending out the poll response frames. This is handled partially in the driver and partially in mac80211. In order to do all this correctly, we need to * keep track of how many frames are pending for each associated client station (avoid doing it for other stations to avoid the atomic ops) * tell mac80211 that we driver-block the PS status while there are still frames pending on the queues, and once they are all rejected (due to the dest sta being in PS) unblock mac80211 Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.
