2008-01-28mac80211: clean up eapol handling in TX pathJohannes Berg
The previous patch left only one user of the ieee80211_is_eapol() function and that user can be eliminated easily by introducing a new "frame is EAPOL" flag to handle the frame specially (we already have this information) instead of doing the (expensive) ieee80211_is_eapol() all the time. Also, allow unencrypted frames to be sent when they are injected. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

After this patch * EAPOL frames addressed to us or the EAPOL group address are always accepted regardless of whether they are encrypted or not * other frames from a station are dropped if PAE is enabled and the station is not authorized * unencrypted frames (except the EAPOL frames above) are dropped if drop_unencrypted is enabled * some superfluous code that eth_type_trans handles anyway is gone * port control is done for transmitted packets Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

2008-01-28mac80211: hardware scan reworkZhu Yi
The scan code in mac80211 makes the software scan assumption in various places. For example, we stop the Tx queue during a software scan so that all the Tx packets will be queued by the stack. We also drop frames not related to scan in the software scan process. But these are not true for hardware scan. Some wireless hardwares (for example iwl3945/4965) has the ability to perform the whole scan process by hardware and/or firmware. The hardware scan is relative powerful in that it tries to maintain normal network traffic while doing a scan in the background. Some drivers (i.e iwlwifi) do provide a way to tune the hardware scan parameters (for example if the STA is associated, what's the max time could the STA leave from the associated channel, how long the scans get suspended after returning to the service channel, etc). But basically this is transparent to the stack. mac80211 should not stop Tx queues or drop Rx packets during a hardware scan. This patch resolves the above problem by spliting the current scan indicator local->sta_scanning into local->sta_sw_scanning and local->sta_hw_scanning. It then changes the scan related code to be aware of hardware scan or software scan in various places. With this patch, iwlwifi performs much better in the scan-while-associated condition and disable_hw_scan=1 should never be required.

2007-10-10[PATCH] mac80211: fix iff_promiscs, iff_allmultis raceJohannes Berg
When we update the counters iff_promiscs and iff_allmultis in struct ieee80211_local we have no common lock held to protect them. The problem is that the update to each counter may not be atomic, so we could end up with iff_promiscs == -1 in unfortunate conditions. To fix it, use atomic_t values. It doesn't matter whether the two counters are updated together atomically or not, if there are two invocations of set_multicast_list we will end up with multiple configure_filter() invocations of which the latter will always be correct.

2007-10-10[PATCH] mac80211: fix virtual interface lockingJohannes Berg

This patch removes the sub_if_lock used by mac80211 in favour of using an RCU list. All list manipulations are already done under rtnl so are well protected against each other, and the read-side locks we took in the RX and TX code are already in RCU read-side critical sections.

2007-10-10[PATCH] mac80211: revamp interface and filter configurationJohannes Berg
Drivers are currently supposed to keep track of monitor interfaces if they allow so-called "hard" monitor, and they are also supposed to keep track of multicast etc. This patch changes that, replaces the set_multicast_list() callback with a new configure_filter() callback that takes filter flags (FIF_*) instead of interface flags (IFF_*). For a driver, this means it should open the filter as much as necessary to get all frames requested by the filter flags. Accordingly, the filter flags are named "positively", e.g. FIF_ALLMULTI. Multicast filtering is a bit special in that drivers that have no multicast address filters need to allow multicast frames through when either the FIF_ALLMULTI flag is set or when the mc_count value is positive. At the same time, drivers are no longer notified about monitor interfaces at all, this means they now need to implement the start() and stop() callbacks and the new change_filter_flags() callback. Also, the start()/stop() ordering changed, start() is now called *before* any add_interface() as it really should be, and stop() after any remove_interface(). The patch also changes the behaviour of setting the bssid to multicast for scanning when IEEE80211_HW_NO_PROBE_FILTERING is set; the IEEE80211_HW_NO_PROBE_FILTERING flag is removed and the filter flag FIF_BCN_PRBRESP_PROMISC introduced. This is a lot more efficient for hardware like b43 that supports it and other hardware can still set the BSSID to all-ones.

2007-10-10[MAC80211]: rework key handlingJohannes Berg
This moves all the key handling code out from ieee80211_ioctl.c into key.c and also does the following changes including documentation updates in mac80211.h: 1) Turn off hardware acceleration for keys when the interface is down. This is necessary because otherwise monitor interfaces could be decrypting frames for other interfaces that are down at the moment. Also, it should go some way towards better suspend/resume support, in any case the routines used here could be used for that as well. Additionally, this makes the driver interface nicer, keys for a specific local MAC address are only ever present while an interface with that MAC address is enabled. 2) Change driver set_key() callback interface to allow only return values of -ENOSPC, -EOPNOTSUPP and 0, warn on all other return values. This allows debugging the stack when a driver notices it's handed a key while it is down. 3) Invert the flag meaning to KEY_FLAG_UPLOADED_TO_HARDWARE. 4) Remove REMOVE_ALL_KEYS command as it isn't used nor do we want to use it, we'll use DISABLE_KEY for each key. It is hard to use REMOVE_ALL_KEYS because we can handle multiple virtual interfaces with different key configuration, so we'd have to keep track of a lot of state for this and that isn't worth it. 5) Warn when disabling a key fails, it musn't. 6) Remove IEEE80211_HW_NO_TKIP_WMM_HWACCEL in favour of per-key IEEE80211_KEY_FLAG_WMM_STA to let driver sort it out itself. 7) Tell driver that a (non-WEP) key is used only for transmission by using an all-zeroes station MAC address when configuring. 8) Change the set_key() callback to have access to the local MAC address the key is being added for.

2007-10-10[MAC80211]: embed key conf in key, fix driver interfaceJohannes Berg
This patch embeds the struct ieee80211_key_conf into struct ieee80211_key and thus avoids allocations and having data present twice. This required some more changes: 1) The removal of the IEEE80211_KEY_DEFAULT_TX_KEY key flag. This flag isn't used by drivers nor should it be since we have a set_key_idx() callback. Maybe that callback needs to be extended to include the key conf, but only a driver that requires it will tell. 2) The removal of the IEEE80211_KEY_DEFAULT_WEP_ONLY key flag. This flag is global, so it shouldn't be passed in the key conf structure. Pass it to the function instead. Also, this patch removes the AID parameter to the set_key() callback because it is currently unused and the hardware currently cannot know about the AID anyway. I suspect this was used with some hardware that actually selected the AID itself, but that functionality was removed. Additionally, I've removed the ALG_NULL key algorithm since we have ALG_NONE.

2007-10-10[MAC80211]: improved short preamble handlingDaniel Drake
Similarly to CTS protection, whether short preambles are used for 802.11b transmissions should be a per-subif setting, not device global. For STAs, this patch makes short preamble handling automatic based on the ERP IE. For APs, hostapd still uses the prism ioctls, but the write ioctl has been restricted to AP-only subifs. ieee80211_txrx_data.short_preamble (an unused field) was removed. Unfortunately, some API changes were required for the following functions: - ieee80211_generic_frame_duration - ieee80211_rts_duration - ieee80211_ctstoself_duration - ieee80211_rts_get - ieee80211_ctstoself_get Affected drivers were updated accordingly.

2007-10-10[MAC80211]: improve locking of sta_info related structuresMichael Wu
The sta_info code has some awkward locking which prevents some driver callbacks from being allowed to sleep. This patch makes the locking more focused so code that calls driver callbacks are allowed to sleep. It also converts sta_lock to a rwlock.

2007-10-10[MAC80211]: move some rate control functions out of ieee80211.cJohannes Berg
I think these can go with rate control just as well and it makes ieee80211.c more readable. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: Jiri Benc <jbenc@suse.cz> Signed-off-by: John W. Linville <linville@tuxdriver.com>
