It does not make sense to keep a station alive if it is not authorised at all. If IBSS/RSN is used it could also be the case that something went wrong during the keys exchange and the stations ended up in a not recoverable state. By not updating last_rx we are giving the station a chance to be deleted and to start the key exchange once again from scratch.

The function cfg80211_get_p2p_attr() can fail and returns a negative error code. However, the return type is unsigned int. The largest positive number is determined by desired_len variable in the function, which is u16. So changing the return type to int to allow easy error checking. Also change the type for the attribute to enum for improved type checking.

Currently, mac80211 checks the DS params IE if present and uses it for the (primary) BSS channel, instead of the one that the frame was received on. This is particularly useful in the 2.4 GHz band since a frame is often received on one of the adjacent channels due to overlap. Move this code to cfg80211 so other drivers also do this. Additionally, on 5 GHz, in particular with some (possibly) upcoming changes in 802.11ai and duplicate transmissions when wider channels are used, something similar happens. So if present, also use the (primary) channel information contained in the HT operation IE. Signed-off-by: NJohannes Berg <johannes.berg@intel.com>

If the AP doesn't support HT, or more importantly if it does but we have to disable it because its IEs are broken, don't advertise HT support in our association request. Otherwise, we configure our channel to be a 20 MHz non-HT channel but the AP might still think we support HT, or even 40 MHz. Signed-off-by: NJohannes Berg <johannes.berg@intel.com>

If the driver doesn't support 40 MHz channels, then mac80211 erroneously sets number of RX chains to one although the number of chains is independent of the support for 40 MHz channels. Fix this by checking the 40 MHz support only for the code that sets the 40 MHz channel not the complete HT code block. This also means the HT20 channel type will always be set in the changed code block so there's no need to set it in case we override the AP due to invalid IEs in the probe response/beacon. The indentation is a bit quirky, but I'm rewriting this code for VHT support so this will change again very soon. Signed-off-by: NJohannes Berg <johannes.berg@intel.com>

Sujith reported warnings with suspend/resume due to channel contexts. When I looked into it, I realised that the code was completely broken as it unassigned the channel contexts when suspending, which actually means they are destroyed. Eliad Peller then pointed out that we also need to remove the channel contexts from the driver. When I looked into this, I also noticed that the code isn't handling the virtual monitor interface correctly (if it exists.) Fix this by calling just the driver methods (if they are implemented) instead of using the channel context management code. Also add reconfiguration for the virtual monitor interface.

The NL80211_CMD_TDLS_OPER command was previously used only for userspace request for the kernel code to perform TDLS operations. However, there are also cases where the driver may need to request operations from userspace, e.g., when using security on the AP path. Add a new cfg80211 function for generating a TDLS operation event for drivers to request a new link to be set up (NL80211_TDLS_SETUP) or an existing link to be torn down (NL80211_TDLS_TEARDOWN). Drivers can optionally use these events, e.g., based on noticing data traffic being sent to a peer station that is seen with good signal strength.

In some cases, in particular for experimentation, it can be useful to be able to add vendor namespace data to received frames in addition to the normal radiotap data. Allow doing this through mac80211 by adding fields to the RX status descriptor that describe the data while the data itself is prepended to the frame. Also add some example code to hwsim, but don't enable it because it doesn't use a proper OUI identifier. Signed-off-by: NJohannes Berg <johannes.berg@intel.com>

During testing our mac80211 driver a fatal error occurred which was signalled to mac80211. Upon performing the reconfiguration of the device a WARN_ON was triggered. This warning checked the return value of drv_add_chanctx(). However, this returns -EOPNOTSUPP when the driver does not provide the callback. As the callback is optional better check it is defined before calling drv_add_chanctx(). Signed-off-by: NArend van Spriel <arend@broadcom.com> Signed-off-by: NJohannes Berg <johannes.berg@intel.com>

During hardware restart, all interfaces are iterated even though they haven't been re-added to the driver, document this behaviour. The same also happens during resume, which is even more confusing since all of the interfaces were previously removed from the driver. Make this optional so drivers relying on the current behaviour can still use it, but to let drivers that don't want this behaviour disable it. Also convert all API users, keeping the old semantics except in hwsim, where the new normal ones are desired. Signed-off-by: NJohannes Berg <johannes.berg@intel.com>

Parsing the P2P attributes can be tricky as their contents can be split across multiple (vendor) IEs. Thus, it's not possible to parse them like IEs (by returning a pointer to the data.) Instead, provide a function that copies the attribute data into a caller-provided buffer and returns the size needed (useful in case the buffer was too small.)

The TX status reporting is done for both the nl80211 report as well as the socket option. The socket option is also reported when an skb is dropped to guarantee that the copy in the IDR tree is freed and status is reported to userspace. However, when a frame is dropped, no nl80211 status is reported. This can cause userspace to stop making progress while waiting for a status notification. Combine the nl80211 and socket option status reporting into a new function and call it in both places -- when the status comes in from the driver and when the skb is dropped. While at it, also simplify the code in the nl80211 portion a bit. Signed-off-by: NJohannes Berg <johannes.berg@intel.com>
