40e9a3f326 RRM: Fix beacon report scan channels for VHT 80, 80+80, 160 MHz cases
ieee80211_chan_to_freq() is not really meant for conversion of 20 MHz
primary channel numbers for wider VHT channels, so handle those as
special cases here for now.

5cda350896 RRM: Move wpabuf_resize() call into wpas_rrm_report_elem()
wpabuf_resize() can handle the initial allocation of a wpabuf and all
the other callers of wpas_rrm_report_elem() were already using a pointer
to a pointer and a wpabuf_resize() call. Simplify this by resizing the
wpabuf (if needed) within wpas_rrm_report_elem() instead of having to
calculate the needed size in all the callers. Thsi is also fixing one of
the allocation sizes to use the correct size instead of a size of a
struct that has nothing to do with the allocation (but is larger than
the needed five octets, so does not break anything).

f2058f4afa RRM: Remove unnecessary cb check

c16b9f8d33 driver: Add scan support to beacon report
Add the following parameters to scan request:
 1. Dwell time on each channel.
 2. Whether the specified dwell time is mandatory.

In addition, add to scan results info the time that the scan actually
started, and to each scan result the time the beacon/probe was received,
both in terms of TSF of the BSS that the interface that requested the
scan is connected to (if available).

Add flags to indicate whether the driver supports dwell time
configuration and scan information reporting.

This scan configuration and information is required to support beacon
report radio measurement.

6a31440b86 Fix LCI request subelement processing
Commit 4a742011ab ('wpa_supplicant: Handle
LCI request') introduced LCI request parsing in a manner that
incremented the request pointer by four within
wpas_rrm_build_lci_report() without decrementing len correspondingly.
This could potentially result in get_ie() reading four octets beyond the
buffer if a corrupted request is received. This would be applicable only
if the LCI reporting was enabled explicitly ("SET LCI ..." control
interface command).

Fix this by updating the len variable to match the request pointer
changes.

3459381dd2 External persistent storage for PMKSA cache entries
This adds new wpa_supplicant control interface commands PMKSA_GET and
PMKSA_ADD that can be used to store PMKSA cache entries in an external
persistent storage when terminating a wpa_supplicant process and then
restore those entries when starting a new process. The previously added
PMKSA-CACHE-ADDED/REMOVED events can be used to help in synchronizing
the external storage with the memory-only volatile storage within
wpa_supplicant.

"PMKSA_GET <network_id>" fetches all stored PMKSA cache entries bound to
a specific network profile. The network_id of the current profile is
available with the STATUS command (id=<network_id). In addition, the
network_id is included in the PMKSA-CACHE-ADDED/REMOVED events. The
output of the PMKSA_GET command uses the following format:

<BSSID> <PMKID> <PMK> <reauth_time in seconds> <expiration in seconds>
<akmp> <opportunistic>

For example:

02:00:00:00:03:00 113b8b5dc8eda16594e8274df4caa3d4 355e98681d09e0b69d3a342f96998aa765d10c4459ac592459b5efc6b563eff6 30240 43200 1 0

The PMKSA_GET command uses the following format:

<network_id> <BSSID> <PMKID> <PMK> <reauth_time in seconds> <expiration
in seconds> <akmp> <opportunistic>

(i.e., "PMKSA_ADD <network_id> " prefix followed by a line of PMKSA_GET
output data; however, the reauth_time and expiration values need to be
updated by decrementing them by number of seconds between the PMKSA_GET
and PMKSA_ADD commands)

For example:

PMKSA_ADD 0 02:00:00:00:03:00 113b8b5dc8eda16594e8274df4caa3d4 355e98681d09e0b69d3a342f96998aa765d10c4459ac592459b5efc6b563eff6 30140 43100 1 0
PMKSA_ADD 0 02:00:00:00:04:00 bbdac8607aaaac28e16aacc9152ffe23 e3dd6adc390e685985e5f40e6fe72df846a0acadc59ba15c208d9cb41732a663 30140 43100 1 0

This functionality is disabled be default and can be enabled with
CONFIG_PMKSA_CACHE_EXTERNAL=y build configuration option. It should be
noted that this allows any process that has access to the wpa_supplicant
control interface to use PMKSA_ADD command to fetch keying material
(PMK), so this is for environments in which the control interface access
is restricted.

Commit 8e84921efe ('P2P: Support driver

checking of the index only after having read a value from the array.
That could in theory read one entry beyond the end of the stack buffer.

Fix this by moving the index variable check to be done before using it
to fetch a value from the array.

This code is used only if wpa_supplicant is build with
CONFIG_DRIVER_NL80211_QCA=y and if the driver supports the vendor
extension (get_pref_freq_list() driver op). In addition, the driver
would need to return more than P2P_MAX_PREF_CHANNELS (= 100) preferred
channels for this to actually be able to read beyond the buffer. No
driver is known to return that many preferred channels, so this does not
seem to be reachable in practice.
