755aaeb97f wpa_supplicant: Add missing memory allocation checks
There are several cases where memory allocations are not
checked for success. Add conditions and error messages, as some
analyzers complain about that.

e9b4ad2364 OpenSSL: Apply connection flags before reading certificates
This is needed to be able to drop the OpenSSL security level, if
necessary, for cases where old certificates (e.g., something using SHA-1
signatures) are still needed. openssl_ciphers="DEFAULT@SECLEVEL=0" can
achieve this, but only if applied before attempting to load the

 - store public key hash in PMKSA from DPP Network

d8d2b3a338 Implement read-only mode for SSIDs from the additional config (-I)
On NixOS[1] - a Linux distribution which allows to configure a full OS
declaratively - it's possible to configure SSIDs for `wpa_supplicant`
like this:

    networking.wireless.networks = {
      myssid = {
        pskRaw = "<redacted>";
      };
    };

It's also possible to add networks "imperatively" using `wpa_gui` or
`wpa_cli`. However it's not possible to do both because if the first
option is used, NixOS creates a read-only symlink at
`/etc/wpa_supplicant.conf` and then it's not possible for
`wpa_supplicant` anymore to write to it.

This patch aims to help us changing this: while "declarative" SSID
configuration can be quite useful, it's a bad idea for e.g. sensitive
stuff like a WPA2 enterprise network.

The original idea was to use `-I`[2] for immutable configs (including
"declarative" networks) on NixOS and `-c /etc/wpa_supplicant.conf` for
anything "imperative".

However this doesn't really work out because if a wifi network from a
config file specified with `-I` is changed by e.g. `wpa_gui`, it's
silently overwritten in `/etc/wpa_supplicant.conf` (specified with
`-c`) which is IMHO unintuitive (in our case at least). This patch
basically declares each network defined in a config file passed via `-I`
to `wpa_supplicant` as "read-only" and doesn't write these "read-only"
networks to `/etc/wpa_supplicant.conf`.

A bit more context can be found on GitHub in the PR where I implemented
this[3].

9025def55c wpa_supplicant: Add support for pregenerated MAC
Add new 'mac_addr' policy (3) with which supplicant expects to also
obtain 'mac_value' with pregenerated value of MAC address to be used for
given SSID.

The main difference between this policy and policy 1 is the ability to
control persistence of the MAC address used.  For example if there is
a requirement to always use the same (but random) MAC address for given
SSID (even if user removes/forgets the network) this could be handled
outside of the wpa_supplicant by using some SSID based hashing scheme to
generate MAC (or by just storing the randomly generated one) and
providing it to wpa_supplicant together with mac_addr=3 policy.

6af717f73b DPP: Don't close TCP connection for duplicate Presence Announcements
If wpa_supplicant receives a duplicate DPP chirp over a TCP connection
this causes the connection (and all of its state) to be torn down.
Such a tear-down means that the authentication request state is discarded.
That in turn will cause any otherwise valid authentication response
to not succeed.

This commit addresses that problem. It also does not attempt to check
for duplicates until at least we know that we have an appropriate hash.

af1528a128 hostapd: Add RELOAD_BSS
When using multiple BSSes on a single radio, it is sometimes desirable
to reconfigure one BSS, without disconnecting the stations already
connected to other BSSes on the same radio.

When a BSS is reconfigured using the SET command, there is no "old"
configuration we can compare to (so we cannot compare a hash of the
configuration for example).

One possible solution would be to make the current RELOAD command
reload only the current BSS. However, that could break the workflow of
existing users. Instead, introduce a new RELOAD_BSS command, which
reloads only the current BSS.

98e9d553f2 nl80211: Check previous MAC address for locally-generated-deauth
When using MAC randomization wpa_supplicant can change the local MAC
address during roaming scenario:

1. We attach to AP1 (with MAC1/SSID1).
2. Roaming to AP2 (with MAC2/SSID2) is started:
  a) we send DEAUTH(for AP1, with MAC1)
  b) we change MAC to MAC2 due to randomization
  c) we start authentication for AP2
  d) we get notification about DEAUTH for AP1 (which we ignore)
  e) we complete association with AP2

In point 2d we completely ignore the notification which later causes
problems. This happens if the deauthentication event is generated by the
local driver (e.g., due to beacon loss) instead of AP2 sending an
explicit Deauthentication frame.

The intended behavior is as follows: during roaming we generate DEAUTH
(2a) and signal this event right away. To protect from handling of our
own DEAUTH for the 2nd time supplicant marks 'ignore_next_local_deauth'
variable.  In point 2d we should receive this notification and clear the
flag but this does not happen because MAC1 in the notification is not
the current MAC address (it has been changed in 2b) so this notification
is ignored as a one with a "foreign" address.

So we end up successfully at AP2 but with 'ignore_next_local_deauth'
still set which causes problems.  For example if AP2 shuts down it has
been observed on some drivers that the DEAUTH notification is generated
as a local one and since we have flag to ignore it nothing is reported
over D-Bus.

To address the problem let's store the previously used MAC address and
use it for checking for foreign address (in combination with the current
one).
