2020-09-28mac80211: encode listen interval for S1GThomas Pedersen
S1G allows listen interval up to 2^14 * 10000 beacon intervals. In order to do this listen interval needs a scaling factor applied to the lower 14 bits. Calculate this and properly encode the listen interval for S1G STAs. See IEEE802.11ah-2016 Table 9-44a for reference.

The S1G beacon is an extension frame as opposed to management frame for the regular beacon. This means we may have to occasionally cast the frame buffer to a different header type. Luckily this isn't too bad as scan results mostly only care about the IEs.

2020-08-03mac80211: Handle special status codes in SAE commitJouni Malinen
SAE authentication has been extended with H2E (IEEE 802.11 REVmd) and PK (WFA) options. Those extensions use special status code values in the SAE commit messages (Authentication frame with transaction sequence number 1) to identify which extension is in use. mac80211 was interpreting those new values as the AP denying authentication and that resulted in failure to complete SAE authentication in some cases. Fix this by adding exceptions for the new status code values 126 and 127.

2020-05-31mac80211: check the correct bit for EMA APShaul Triebitz
An AP supporting EMA (Enhanced Multi-BSSID advertisement) should set bit 83 in the extended capabilities IE (9.4.2.26 in the 802.11ax D5 spec). So the *3rd* bit of the 10th byte should be checked. Also, in one place, the wrong byte was checked. (cfg80211_find_ie returns a pointer to the beginning of the IE, so the data really starts at ie[2], so the 10th byte should be ie[12]. To avoid this confusion, use cfg80211_find_elem instead).

2020-05-27cfg80211: Replace zero-length array with flexible-arrayGustavo A. R. Silva
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] sizeof(flexible-array-member) triggers a warning because flexible array members have incomplete type[1]. There are some instances of code in which the sizeof operator is being incorrectly/erroneously applied to zero-length arrays and the result is zero. Such instances may be hiding some bugs. So, this work (flexible-array member conversions) will also help to get completely rid of those sorts of issues. This issue was found with the help of Coccinelle.

Somehow we missed this for a long time, but similar to the extended NSS support in VHT capabilities, we need to have this in Operating Mode notification. Implement it by * parsing the 160/80+80 bit there and setting the bandwidth appropriately * having callers of ieee80211_get_vht_max_nss() pass in the current max NSS value as received in the operating mode notification in order to modify it appropriately depending on the extended NSS bits.

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.

2019-02-08ieee80211: fix for_each_element_extid()Johannes Berg
The data/datalen argument names cannot be used as those are also the struct element names, fix that. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2019-02-08mac80211: indicate support for multiple BSSIDSara Sharon
Set multi-bssid support flags according to driver support. Signed-off-by: Sara Sharon <sara.sharon@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2019-02-08mac80211: support multi-bssidSara Sharon
Add support for multi-bssid. This includes: - Parsing multi-bssid element - Overriding DTIM values - Taking into account in various places the inner BSSID instead of transmitter BSSID - Save aside some multi-bssid properties needed by drivers Signed-off-by: Sara Sharon <sara.sharon@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2019-02-08cfg80211: add and use strongly typed element iteration macrosJohannes Berg
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>
