7d67192493 sae: Make sae_compute_pwe independent of sae_sm
sae_compute_pwe doesn't really depend on the state of sae_sm.  Only the
curve to be used for the PWE calculation is needed.  Rework the function
signature to reflect that and remove unneeded member of struct sae_sm.

08845fb19c ie: Change ie_tlv_builder_finalize signature
ie_tlv_builder_init takes a size_t as input, yet for some reason
ie_tlv_builder_finalize takes an unsigned int argument as output.  Fix
the latter to use size_t as well.

2a66b3bfe5 network: Move handshake parameter setup from station
Most parameters set into the handshake object are actually known by the
network object itself and not station.  This includes address
randomization settings, EAPoL settings, passphrase/psk/8021x settings,
etc.  Since the number of these settings will only keep growing, move
the handshake setup into network itself.  This also helps keep network
internals better encapsulated.

869bcf59d5 network: Make network_sync_psk not repetitive
Refactor network_sync_psk to not require setting attributes into
multiple settings objects.  This is in fact unnecessary as the parsed
security parameters are used everywhere else instead.  Also make sure to
wipe the [Security] group first, in case any settings were invalid
during loading or otherwise invalidated.

10e5bee5ef wsc: Properly write provisioning files with a passphrase
Credentials obtained can now be either in passphrase or PSK form.  Prior
to commit 7a9891dbef, passphrase credentials were always converted to
PSK form by invoking crypto_psk_from_passphrase.  This was changed in
order to support WPA3 networks.  Unfortunately the provisioning logic
was never properly updated.  Fix that, and also try to not overwrite any
existing settings in case WSC is providing credentials for networks that
are already known.

Fixes: 7a9891dbef ("wsc: store plain text passphrase if available")

dfdc8716be network: Rename _sync_psk to _sync_settings
There will be additional security-related settings that will be
introduced for settings files.  In particular, Hash-to-Curve PT
elements, Transition Disable settings and potentially others in the
future.  Since PSK is now not the only element that would require
update, rename this function to better reflect this.

fbe8b7a3c0 crypto: Add prf_plus function
PRF+ from RFC 5295 is the more generic function using which HKDF_Expand
is defined.  Allow this function to take a vararg list of arguments to
be hashed (these are referred to as 'S' in the RFCs).

Implement hkdf_expand in terms of prf_plus and update all uses to the
new syntax.

ed283d7b14 iwd.service: Add CAP_NET_BIND_SERVICE
This fixes an issue where the udp port was not being opened due to a
permission denied error. The result of this was the dhcp client would
fail to send the renewal request and so the dhcp lease would expire.

The addition of the CAP_NET_BIND_SERVICE capability allows the service
to open sockets in the restricted port range (<1024) which is required
for dhcp.

b6236255d2 Send hostname as part of DHCP request.
This is based on a previous patch by Roberto Santalla Fernández.

A new config is introduced into the network config file under IPv4
called SendHostname. If this is set to true then we add the hostname
into all DHCP requests. The default is false.
