Add a new "peer measurement" API, that can be used to measure certain things related to a peer. Right now, only implement FTM (flight time measurement) over it, but the idea is that it'll be extensible to also support measuring the necessary things to calculate e.g. angle-of-arrival for WiGig. The API is structured to have a generic list of peers and channels to measure with/on, and then for each of those a set of measurements (again, only FTM right now) to perform. Results are sent to the requesting socket, including a final complete message. Closing the controlling netlink socket will abort a running measurement. v3: - add a bit to report "final" for partial results - remove list keeping etc. and just unicast out the results to the requester (big code reduction ...) - also send complete message unicast, and as a result remove the multicast group - separate out struct cfg80211_pmsr_ftm_request_peer from struct cfg80211_pmsr_request_peer - document timeout == 0 if no timeout - disallow setting timeout nl80211 attribute to 0, must not include attribute for no timeout - make MAC address randomization optional - change num bursts exponent default to 0 (1 burst, rather rather than the old default of 15==don't care) v4: - clarify NL80211_ATTR_TIMEOUT documentation v5: - remove unnecessary nl80211 multicast/family changes - remove partial results bit/flag, final is sufficient - add max_bursts_exponent, max_ftms_per_burst to capability - rename "frames per burst" -> "FTMs per burst" v6: - rename cfg80211_pmsr_free_wdev() to cfg80211_pmsr_wdev_down() and call it in leave, so the device can't go down with any pending measurements v7: - wording fixes (Lior) - fix ftm.max_bursts_exponent to allow having the limit of 0 (Lior) v8: - copyright statements - minor coding style fixes - fix error path leak Signed-off-by: NJohannes Berg <johannes.berg@intel.com>

Add support for drivers to report the total number of MPDUs received and the number of MPDUs received with an FCS error from a specific peer. These counters will be incremented only when the TA of the frame matches the MAC address of the peer irrespective of FCS error. It should be noted that the TA field in the frame might be corrupted when there is an FCS error and TA matching logic would fail in such cases. Hence, FCS error counter might not be fully accurate, but it can provide help in detecting bad RX links in significant number of cases. This FCS error counter without full accuracy can be used, e.g., to trigger a kick-out of a connected client with a bad link in AP mode to force such a client to roam to another AP.

Make wmm_rule be part of the reg_rule structure. This simplifies the code a lot at the cost of having bigger memory usage. However in most cases we have only few reg_rule's and when we do have many like in iwlwifi we do not save memory as it allocates a separate wmm_rule for each channel anyway.

由 Denis Kenzior 提交于
The current implementation of cfg80211_rx_control_port assumed that the caller could provide a contiguous region of memory for the control port frame to be sent up to userspace. Unfortunately, many drivers produce non-linear skbs, especially for data frames. This resulted in userspace getting notified of control port frames with correct metadata (from address, port, etc) yet garbage / nonsense contents, resulting in bad handshakes, disconnections, etc. mac80211 linearizes skbs containing management frames. But it didn't seem worthwhile to do this for control port frames. Thus the signature of cfg80211_rx_control_port was changed to take the skb directly. nl80211 then takes care of obtaining control port frame data directly from the (linear | non-linear) skb. The caller is still responsible for freeing the skb, cfg80211_rx_control_port does not take ownership of it.

The BIT macro uses unsigned long which some architectures handle as 32 bit and therefore might cause macro's shift to overflow when used on a value equals or larger than 32 (NL80211_STA_INFO_RX_DURATION and afterwards). Since 'filled' member in station_info changed to u64, BIT_ULL macro should be used with all NL80211_STA_INFO_* attribute types instead of BIT to prevent future possible bugs when one will use BIT macro for higher attributes by mistake. This commit cleans up all usages of BIT macro with the above field in cfg80211 by changing it to BIT_ULL instead. In addition, there are some places which don't use BIT nor BIT_ULL macros so align those as well.

由 Bob Copeland 提交于
Commit 9757235f, "nl80211: correct checks for NL80211_MESHCONF_HT_OPMODE value") relaxed the range for the HT operation field in meshconf, while also adding checks requiring the non-greenfield and non-ht-sta bits to be set in certain circumstances. The latter bit is actually reserved for mesh BSSes according to Table 9-168 in 802.11-2016, so in fact it should not be set. wpa_supplicant sets these bits because the mesh and AP code share the same implementation, but authsae does not. As a result, some meshconf updates from authsae which set only the NONHT_MIXED protection bits were being rejected. In order to avoid breaking userspace by changing the rules again, simply accept the values with or without the bits set, and mask off the reserved bit to match the spec. While in here, update the 802.11-2012 reference to 802.11-2016.

The kzalloc() function has a 2-factor argument form, kcalloc(). This patch replaces cases of: kzalloc(a * b, gfp) with: kcalloc(a * b, gfp) as well as handling cases of: kzalloc(a * b * c, gfp) with: kzalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kzalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kzalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant.

With the addition of TXQ stats in the per-tid statistics the struct station_info grew significantly. This resulted in stack size warnings due to the structure itself being above the limit for the warnings. Add an allocation function that those who want to provide per-tid stats should use to allocate the tid array, i.e. struct station_info::pertid.

Allocation size of nlmsg in cfg80211_ft_event is based on ric_ies_len and doesn't take into account ies_len. This leads to NL80211_CMD_FT_EVENT message construction failure in case ft_event contains large enough ies buffer. Add ies_len to the nlmsg allocation size.
