| * mac80211: check defrag PN against current frameJohannes Berg2021-06-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit bf30ca922a0c0176007e074b0acc77ed345e9990 upstream. As pointed out by Mathy Vanhoef, we implement the RX PN check on fragmented frames incorrectly - we check against the last received PN prior to the new frame, rather than to the one in this frame itself. Prior patches addressed the security issue here, but in order to be able to reason better about the code, fix it to really compare against the current frame's PN, not the last stored one.

| * mac80211: add ieee80211_is_any_nullfunc()Thomas Pedersen2020-05-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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).

| * cfg80211: add and use strongly typed element iteration macrosJohannes Berg2019-10-17

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 <johannes.berg@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

* mac80211: support DTPC IE (from Cisco Client eXtensions)Steinar H. Gunderson2014-09-08
| | | | | | | | | | | | | | | | | | | | | | | | Linux already supports 802.11h, where the access point can tell the client to reduce its transmission power. However, 802.11h is only defined for 5 GHz, where the need for this is much smaller than on 2.4 GHz. Cisco has their own solution, called DTPC (Dynamic Transmit Power Control). Cisco APs on a controller sometimes but not always send 802.11h; they always send DTPC, even on 2.4 GHz. This patch adds support for parsing and honoring the DTPC IE in addition to the 802.11h element (they do not always contain the same limits, so both must be honored); the format is not documented, but very simple. Tested (on top of wireless.git and on 3.16.1) against a Cisco Aironet 1142 joined to a Cisco 2504 WLC, by setting various transmit power levels for the given access points and observing the results. The Wireshark 802.11 dissector agrees with the interpretation of the element, except for negative numbers, which seem to never happen anyway. Signed-off-by: Steinar H.

* | ieee80211: remove function ieee80211_{dsss_chan_to_freq, freq_to_dsss_chan}Zhao, Gang2014-02-28
|/ | | | | | | | | | | Function ieee80211_{dsss_chan_to_freq, freq_to_dsss_chan} have been replaced with ieee80211_{channel_to_frequency, frequency_to_channel}. There should be no users of the two functions now. So remove them. Cc: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Zhao, Gang <gamerh2o@gmail.com> Signed-off-by: John W.

* wireless: sort and extend element ID listJohannes Berg2014-02-05

* mac80211: fix bufferable MMPDU RX handlingJohannes Berg2014-02-04
| | | | | | | | | | | | | | | Action, disassoc and deauth frames are bufferable, and as such don't have the PM bit in the frame control field reserved which means we need to react to the bit when receiving in such a frame. Fix this by introducing a new helper ieee80211_is_bufferable_mmpdu() and using it for the RX path that currently ignores the PM bit in any non-data frames for doze->wake transitions, but listens to it in all frames for wake->doze transitions, both of which are wrong. Also use the new helper in the TX path to clean up the code. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
* mac80211: add length check in ieee80211_is_robust_mgmt_frame()Johannes Berg2014-02-04
| | | | | | | | | | | A few places weren't checking that the frame passed to the function actually has enough data even though the function clearly documents it must have a payload byte. Make this safer by changing the function to take an skb and checking the length inside. The old version is preserved for now as the rtl* drivers use it and don't have a correct skb.

Transmit restrict field and others are maintained as is. * No beacon or probe response frame are handled here. Also, introduce the debug message used for mesh CSA purpose.
