2008-07-29mac80211: partially fix skb->cb useJohannes Berg
This patch fixes mac80211 to not use the skb->cb over the queue step from virtual interfaces to the master. The patch also, for now, disables aggregation because that would still require requeuing, will fix that in a separate patch. There are two other places (software requeue and powersaving stations) where requeue can happen, but that is not currently used by any drivers/not possible to use respectively.

2008-07-14mac80211: fix TX sequence numbersJohannes Berg
This patch makes mac80211 assign proper sequence numbers to QoS-data frames. It also removes the old sequence number code because we noticed that only the driver or hardware can assign sequence numbers to non-QoS-data and especially management frames in a race-free manner because beacons aren't passed through mac80211's TX path. This patch also adds temporary code to the rt2x00 drivers to not break them completely, that code will have to be reworked for proper sequence numbers on beacons. It also moves sequence number assignment down in the TX path so no sequence numbers are assigned to frames that are dropped.

2008-07-14mac80211: revamp beacon configurationJohannes Berg
This patch changes mac80211's beacon configuration handling to never pass skbs to the driver directly but rather always require the driver to use ieee80211_beacon_get(). Additionally, it introduces "change flags" on the config_interface() call to enable drivers to figure out what is changing. Finally, it removes the beacon_update() driver callback in favour of having IBSS beacon delivered by ieee80211_beacon_get() as well.

This is a rewrite of the DMA API for SSB devices. This is needed, because the old (non-existing) "API" made too many bad assumptions on the API of the host-bus (PCI). This introduces an almost complete SSB-DMA-API that maps to the lowlevel bus-API based on the bustype. Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W.

This patch modifies struct ieee80211_tx_control to give band info and the rate index (instead of rate pointers) to drivers.

2008-05-14mac80211: use hardware flags for signal/noise unitsBruno Randolf
trying to clean up the signal/noise code. the previous code in mac80211 had confusing names for the related variables, did not have much definition of what units of signal and noise were provided and used implicit mechanisms from the wireless extensions. this patch introduces hardware capability flags to let the hardware specify clearly if it can provide signal and noise level values and which units it can provide. this also anticipates possible new units like RCPI in the future. for signal: IEEE80211_HW_SIGNAL_UNSPEC - unspecified, unknown, hw specific IEEE80211_HW_SIGNAL_DB - dB difference to unspecified reference point IEEE80211_HW_SIGNAL_DBM - dBm, difference to 1mW for noise we currently only have dBm: IEEE80211_HW_NOISE_DBM - dBm, difference to 1mW if IEEE80211_HW_SIGNAL_UNSPEC or IEEE80211_HW_SIGNAL_DB is used the driver has to provide the maximum value (max_signal) it reports in order for applications to make sense of the signal values. i tried my best to find out for each driver what it can provide and update it but i'm not sure (?) for some of them and used the more conservative guess in doubt. this can be fixed easily after this patch has been merged by changing the hardware flags of the driver.

The hw_key_idx inside the ieee80211_key_conf structure does not provide all the information drivers might need to perform hardware encryption. This is in particular true for rt2x00 who needs to know the key algorithm and whether it is a shared or pairwise key. By passing the ieee80211_key_conf pointer it assures us that drivers can make full use of all information that it should know about a particular key. Additionally this patch updates all drivers to grab the hw_key_idx from the ieee80211_key_conf structure. v2: Removed bogus u16 cast v3: Add warning about ieee80211_tx_control pointers v4: Update warning about ieee80211_tx_control pointers Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Acked-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

2008-02-29cfg80211 API for channels/bitrates, mac80211 and driver conversionJohannes Berg
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.

This adds printk messages with basic information about the driver being loaded. This information includes a summary of the compiled-in features, which simplifies bug-reporting and debugging a lot. Also a firmware ID is printed. This is a unique identifier blob for a specific version of the firmware. This ID is attached to a specific version of the firmware blob in b43-fwcutter (see fwcutter git). This helps users to select the right firmware for their device. This also makes it possible to use automated scripts to fetch and extract the right firmware for the driver. (The script will grep the .ko for the "Firmware-ID: xxx" string.)

2008-02-05b43legacy: drop packets we are not able to encryptStefano Brivio
We must drop any packets we are not able to encrypt. We must not send them unencrypted or with an all-zero-key (which basically is the same as unencrypted, from a security point of view). This might only trigger shortly after resume before mac80211 reassociated and reconfigured the keys. It is safe to drop these packets, as the association they belong to is not guaranteed anymore anyway. This is a security fix in the sense that it prevents information leakage.
