mac80211: add ieee80211_is_any_nullfunc()

2020-05-10T08:29:03Z

commit 30b2f0be23fb40e58d0ad2caf8702c2a44cda2e1 upstream. commit 08a5bdde3812 ("mac80211: consider QoS Null frames for STA_NULLFUNC_ACKED") Fixed a bug where we failed to take into account a nullfunc frame can be either non-QoS or QoS. It turns out there is at least one more bug in ieee80211_sta_tx_notify(), introduced in commit 7b6ddeaf27ec ("mac80211: use QoS NDP for AP probing"), where we forgot to check for the QoS variant and so assumed the QoS nullfunc frame never went out Fix this by adding a helper ieee80211_is_any_nullfunc() which consolidates the check for non-QoS and QoS nullfunc frames. Replace existing compound conditionals and add a couple more missing checks for QoS variant.

cfg80211: Use const more consistently in for_each_element macros

2019-10-11T16:18:49Z

commit 7388afe09143210f555bdd6c75035e9acc1fab96 upstream. Enforce the first argument to be a correct type of a pointer to struct element and avoid unnecessary typecasts from const to non-const pointers (the change in validate_ie_attr() is needed to make this part work). In addition, avoid signed/unsigned comparison within for_each_element() and mark struct element packed just in case.

cfg80211: add and use strongly typed element iteration macros

2019-10-11T16:18:48Z

commit 0f3b07f027f87a38ebe5c436490095df762819be upstream. Rather than always iterating elements from frames with pure u8 pointers, add a type "struct element" that encapsulates the id/datalen/data format of them. Then, add the element iteration macros * for_each_element * for_each_element_id * for_each_element_extid which take, as their first 'argument', such a structure and iterate through a given u8 array interpreting it as elements. While at it and since we'll need it, also add * for_each_subelement * for_each_subelement_id * for_each_subelement_extid which instead of taking data/length just take an outer element and use its data/datalen. Also add for_each_element_completed() to determine if any of the loops above completed, i.e. it was able to parse all of the elements successfully and no data remained. Use for_each_element_id() in cfg80211_find_ie_match() as the first user of this. Signed-off-by: Johannes Berg Signed-off-by: Greg Kroah-Hartman

ieee80211: update public action codes

cfg80211: support 4-way handshake offloading for 802.1X

2017-06-13T08:44:09Z

Add API for setting the PMK to the driver. For FT support, allow setting also the PMK-R0 Name. This can be used by drivers that support 4-Way handshake offload while IEEE802.1X authentication is managed by upper layers.

cfg80211: support 4-way handshake offloading for WPA/WPA2-PSK

2017-06-13T08:43:56Z

Let drivers advertise support for station-mode 4-way handshake offloading with a new NL80211_EXT_FEATURE_4WAY_HANDSHAKE_STA_PSK flag. Extend use of NL80211_ATTR_PMK attribute indicating it might be passed as part of NL80211_CMD_CONNECT command, and contain the PSK (which is the PMK, hence the name.) The driver/device is assumed to handle the 4-way handshake by itself in this case (including key derivations, etc.), instead of relying on the supplicant. This patch is somewhat based on this one (by Vladimir Kondratiev): https://patchwork.kernel.org/patch/1309561/.

mac80211: Add support for BSS max idle period element

2017-04-28T10:28:45Z

Parse the BSS max idle period element and set the BSS configuration accordingly so the driver can use this information to configure the max idle period and to use protected management frames for keep alive when required.
