wpa_supplicant/default.nix currently uses the option "withDbus" to
decide whether or not to compile with dbus support. It is the only
nix package that uses this choice of name. Most other packages use
dbusSupport instead.
Let's rename this option to dbusSupport, so that users desiring to
compile without dbus can set the option once in nixpkgs.conf and have
all packages understand that directive.
For a while now it's possible to specify an additional config file in
`wpa_supplicant`[1]. In contrast to the file specified via `-c` this was
supposed to be used for immutable settings and not e.g. additional
networks.
However I'm a little bit unhappy about the fact that one has to choose
between a fully imperative setup and a fully declarative one where the
one would have to write credentials for e.g. WPA2-enterprise networks
into the store.
The primary problem with the current state of `wpa_supplicant` is that
if the `SAVE_CONFIG` command is invoked (e.g. via `wpa_cli`), all known
networks will be written to `/etc/wpa_supplicant.conf` and thus all
declarative networks would get out of sync with the declarative
settings.
To work around this, I had to change the following things:
* The `networking.wireless`-module now uses `-I` for declarative config,
so the user-controlled mode can be used along with the
`networks`-option.
* I added an `ro`-field to the `ssid`-struct in the
`wpa_supplicant`-sources. This will be set to `1` for each network
specified in the config passed via `-I`.
Whenever config is written to the disk, those networks will be
skipped, so changes to declarative networks are only temporary.

In wpa_supplicant and hostapd 2.9, forging attacks may occur because
AlgorithmIdentifier parameters are mishandled in tls/pkcs1.c and
tls/x509v3.c.
Fixes: CVE-2021-30004
A vulnerability was discovered in how wpa_supplicant processes P2P
(Wi-Fi Direct) provision discovery requests. Under a corner case
condition, an invalid Provision Discovery Request frame could end up
reaching a state where the oldest peer entry needs to be removed. With
a suitably constructed invalid frame, this could result in use
(read+write) of freed memory. This can result in an attacker within
radio range of the device running P2P discovery being able to cause
unexpected behavior, including termination of the wpa_supplicant process
and potentially code execution.

A vulnerability was discovered in how wpa_supplicant processing P2P
(Wi-Fi Direct) group information from active group owners. The actual
parsing of that information validates field lengths appropriately, but
processing of the parsed information misses a length check when storing
a copy of the secondary device types. This can result in writing
attacker controlled data into the peer entry after the area assigned for
the secondary device type. The overflow can result in corrupting
pointers for heap allocations. This can result in an attacker within
radio range of the device running P2P discovery being able to cause
unexpected behavior, including termination of the wpa_supplicant process
and potentially arbitrary code execution.

Fixes: CVE-2021-0326
The wpa_supplicant upstream is slow to push out new releases and has
been asked several times to do so. Support for Opportunistic Wireless
Encryption has been on master since late 2019 and still hasn't made it
into a release yet.
This backports a rather simple patchset to enable OWE key management
and exposes it also via DBus, so it can be used from Network-Manager.
continuation of #109595
pkgconfig was aliased in 2018, however, it remained in
all-packages.nix due to its wide usage. This cleans
up the remaining references to pkgs.pkgsconfig and
moves the entry to aliases.nix.
python3Packages.pkgconfig remained unchanged because
it's the canonical name of the upstream package
on pypi.
There ver very many conflicts, basically all due to
name -> pname+version. Fortunately, almost everything was auto-resolved
by kdiff3, and for now I just fixed up a couple evaluation problems,
as verified by the tarball job. There might be some fallback to these
conflicts, but I believe it should be minimal.

He prefers to contribute to his own nixpkgs fork triton.
Since he is still marked as maintainer in many packages
this leaves the wrong impression he still maintains those.
