This reverts commit a6914dc0dc.
iwinfo currently misses ABI version tracking in OpenWrt, potentially
breaking other packages unintentionally.
Revert this commit for now until this is implemented.
Otherwise, we are not able to safely bump iwinfo at the moment.

This adds support for the BSS load information element. With this patch,
the BSS load information is visible when using the CLI as well as when
accessing scan results using the LUA binding.

The mac80211.sh implementation of the uci "path" option compares the
readlink() results of each /sys/class/ieee80211/*/device link to find
the proper phy directory while iwinfo so far tried to construct a full
path out of the uci value.
The iwinfo approach appears to fail under certain circumstances, e.g.
with Hyper-V systems utilizing PCI passthrough for the radio devices.
This commit mimicks the behaviour of mac80211.sh more closely to
achieve the same results.

When wpa_supplicant responds with FAIL-BUSY in response to the SCAN
command, a scan process is already in process. Instead of failing in
this case, simply keep awaiting the result list.
This also significantly speeds up the scan operation in many cases.

Refactor the parsing of wpa_supplicant scan list results, the wpa_supplicant
status output and the hostapd configuration file format to properly detect
WPA3 key management protocols like SAE, OWE or EAP Suite B.
Signed-off-by: Jo-Philipp Wich <jo@mein.io>
With WPA3 the wpa_key_mgmt string can be longer than 16 bytes. The
sea-mixed setting for example is 27 bytes long:
wpa_key_mgmt=WPA-PSK WPA-PSK-SHA256 SAE
Increase the buffer to better detect more complicated authentication methods.

This patch adds support for WPA3, meaning SAE and OWE are now properly identified.
This fixes iwinfo and LuCi showing WPA2 NONE for WPA3 SAE and OWE.

Do not require a temporary interface just to read the hardware ID numbers
from a given phy name, instead read the data from the ieee80211 sysfs

This patch enables proper identification of ad hwmode in channel2frequency function.
Now iwinfo will properly calculate frequency for a channels 1-6 in 802.11ad.

The wpa_supplicant control socket might reply with "FAIL-BUSY" when
attempting to start a scan while another scanning process is already
running, back out early in this case.

Using average of previous average and the next value is highly
imprecise. E.g. for values 20, 20, 20, 180 it would result in /average/
of 100 (instead of 60). Fix it by storing & using an info of how many
samples were used for the previous calculation.

cfg80211 allows drivers to announce the to-be-expected layer-2 datarate
using the NL80211_STA_INFO_EXPECTED_THROUGHPUT field.
This information is useful as a metric for user-space routing daemons,
so grab it via nl80211 and make it available in both C and Lua APIs,
and show expected throughput on CLI interface assoclist.

Drivers may abort a scan by calling cfg80211_scan_done() with a struct
cfg80211_scan_info that sets aborted to true.
To avoid blocking forever consider both NL80211_CMD_NEW_SCAN_RESULTS
and NL80211_CMD_SCAN_ABORTED when waiting for scan results.
Tested with Broadcom's bcmdhd driver.

Extend the nl82011_wait() function to accept multiple command numbers.
This is useful to wait for different possible results, e.g. either
NL80211_CMD_NEW_SCAN_RESULTS or NL80211_CMD_SCAN_ABORTED.

In order to get more details about each frequency we will need to set
NL80211_ATTR_SPLIT_WIPHY_DUMP in the future. This will result in our
callback being called multiple times. Modify it to support such a
scenario:
1) Start putting new frequencies after the last set one
2) Make sure that attribute is set before iterating it

- introduce a new nl80211_request() which combines nl80211_msg() with
nl80211_send() to simplify calling code
- always invoke nl80211_free() in nl80211_send() and remove explicit
nl80211_free() invocations in callers
- back out early on netlink errors in functions performing multiple
calls, e.g. when fetching scan results
Signed-off-by: Jo-Philipp Wich <jo@mein.io>
Adjust nl80211_send() to propagate errors back to the caller and do not
free message and callbacks in send error case anymore since all callsites
immediately invoke nl80211_free() anyway.

If the first attempt to lookup the phy index by the path value fails, retry to

With the mac80211 commit d55d0d598e66 ("nl80211: put current TX power in
interface info") it is possible now to get TX power using nl80211. As we
don't really support any wext-only drivers it doesn't make sense to
leave wext as a fallback.

The old nl80211_hostapd_info() used a global static buffer which was not
properly zeroed on subsequent invocations, leading to misreported encryption
values when querying multiple radios or radious with multiple vifs.
Also rework and simplify the control socket code for wpa_supplicant by
splitting status query and scan handling.
