* mac80211: fix RX sequence number checkJohannes Berg2008-07-141-7/+12

* mac80211: Fix ieee80211_rx_reorder_ampdu: ignore QoS null packetsEmmanuel Grumbach2008-07-141-2/+2
| | | | | | | | | | | | This patch fixes the check at the entrance to ieee80211_rx_reorder_ampdu. This check has been broken by 'mac80211: rx.c use new helpers'. Letting QoS NULL packet in ieee80211_rx_reorder_ampdu led to packet loss in RX.

* mac80211: make master netdev handling saneJohannes Berg2008-07-141-10/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, almost every interface type has a 'bss' pointer pointing to BSS information. This BSS information, however, is for a _local_ BSS, not for the BSS we joined, so having it on a STA mode interface makes little sense, but now they have it pointing to the master device, which is an AP mode virtual interface. However, except for some bitrate control data, this pointer is only used in AP/VLAN modes (for power saving stations.) Overall, it is not necessary to even have the master netdev be a valid virtual interface, and it doesn't have to be on the list of interfaces either. This patch changes the master netdev to be special, it now - no longer is on the list of virtual interfaces, which lets me remove a lot of tests for that - no longer has sub_if_data attached, since that isn't used Additionally, this patch changes some vlan/ap mode handling that is related to these 'bss' pointers described above (but in the VLAN case they actually make sense because there they point to the AP they belong to); it also adds some debugging code to IEEE80211_DEV_TO_SUB_IF to validate it is not called on the master netdev any more.

* mac80211: rework debug settings and make debugging saferJohannes Berg2008-07-021-94/+12
| | | | | | | | | | | | | This patch reworks the mac80211 debug settings making them more focused and adding help text for those that didn't have one. It also removes a number of printks that can be triggered remotely and add no value, e.g. "too short deauthentication frame received - ignoring". If somebody really needs to debug that they should just add a monitor interface and look at the frames in wireshark. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

* mac80211: get rid of function pointers in RX pathJohannes Berg2008-07-021-53/+44
| | | | | | | | | | | This changes the RX path to no longer use function pointers for RX handlers but rather invoke them directly. If debugging is enabled, mark the RX handlers noinline because otherwise they all get inlined into ieee80211_invoke_rx_handlers() which makes it harder to see where a bug is.

* mac80211: eliminate IBSS warning in rate_lowest_index()Vladimir Koutny2008-06-141-2/+8
| | | | | | | | | | | | | | In IBSS mode prior to join/creation of new IBSS it is possible that a frame from unknown station is received and an ibss_add_sta() is called. This will cause a warning in rate_lowest_index() since the list of supported rates of our station is not initialized yet. The fix is to add ibss stations with a rate we received that frame at; this single-element set will be extended later based on beacon data. Also there is no need to store stations from a foreign IBSS. Signed-off-by: Vladimir Koutny <vlado@ksp.sk> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| * | mac80211: proper STA info lockingJohannes Berg2008-05-141-8/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As discussed earlier, we can unify locking in struct sta_info and use just a single spinlock protecting all members of the structure that need protection. Many don't, but one of the especially bad ones is the 'flags' member that can currently be clobbered when RX and TX is being processed on different CPUs at the same time. Because having four spinlocks for different, mostly exclusive parts of a single structure is overkill, this patch also kills the ampdu and mesh plink spinlocks and uses just a single one for everything. Because none of the spinlocks are nested, this is safe. It remains to be seen whether or not we should make the sta flags use atomic bit operations instead, for now though this is a safe thing and using atomic operations instead will be very simple using the new static inline functions this patch introduces for accessing sta->flags. Since spin_lock_bh() is used with this lock, there shouldn't be any contention even if aggregation is enabled at around the same time as both requires frame transmission/reception which is in a bh context.

* | mac80211: split ieee80211_txrx_resultJohannes Berg2008-02-291-75/+75
| | | | | | | | | | | | | | | | | | | | The _DROP result will need to be split in the RX path but not in the TX path, so for preparation split up the type into two types, one for RX and one for TX. Also make sure (via sparse) that they cannot be confused. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* | mac80211: remove port control enable switch, clean up sta flagsJohannes Berg2008-02-291-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the 802.1X port acess control enable flag since it is not required. Instead, set the authorized flag for each station that we normally communicate with (WDS peers, IBSS peers and APs we're associated to) and require hostapd to set the authorized flag for all stations when port control is not enabled. Also, since I was working in that area, this documents station flags and removes the unused "permanent" one. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

* | cfg80211 API for channels/bitrates, mac80211 and driver conversionJohannes Berg2008-02-291-35/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch creates new cfg80211 wiphy API for channel and bitrate registration and converts mac80211 and drivers to the new API. The old mac80211 API is completely ripped out. All drivers (except ath5k) are updated to the new API, in many cases I expect that optimisations can be done. Along with the regulatory code I've also ripped out the IEEE80211_HW_DEFAULT_REG_DOMAIN_CONFIGURED flag, I believe it to be unnecessary if the hardware simply gives us whatever channels it wants to support and we then enable/disable them as required, which is pretty much required for travelling. Additionally, the patch adds proper "basic" rate handling for STA mode interface, AP mode interface will have to have new API added to allow userspace to set the basic rate set, currently it'll be empty... However, the basic rate handling will need to be moved to the BSS conf stuff. I do expect there to be bugs in this, especially wrt. transmit power handling where I'm basically clueless about how it should work.

* | mac80211: dissolve pre-rx handlersJohannes Berg2008-02-291-59/+37
|/ | | | | | | | | These handlers do not really return a status and the compiler can do a much better job when they're simply static functions that it can inline if appropriate. Also makes the code shorter. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
