[Buildroot] [PATCH 2/2] package/hostapd: bump version to 2.12

[Bernd Kuhls <bernd@kuhls.net>]

https://lists.infradead.org/pipermail/hostap/2026-August/045441.html

Removed patches which are included in this release.

Removed the hostap driver from the package due to its upstream removal:
https://git.w1.fi/cgit/hostap/commit/?id=dfd207d96c1bbc4a2013db638bc1d48cc0865c27

Gitlab pipelines passed:
https://gitlab.com/bkuhls/buildroot/-/commits/1cab64c3f338d06bdf955a31ffebef1f751ffb7b

The build fix for libnl is included in this series because it is needed
for passing all pipelines of the hostapd bump.

-Subject: RADIUS: Drop pending request only when accepting the response
-
-The case of an invalid authenticator in a RADIUS response could imply
-that the response is not from the correct RADIUS server and as such,
-such a response should be discarded without changing internal state for
-the pending request. The case of an unknown response (RADIUS_RX_UNKNOWN)
-is somewhat more complex since it could have been indicated before
-validating the authenticator. In any case, it seems better to change the
-state for the pending request only when we have fully accepted the
-response.
-
-Allowing the internal state of pending RADIUS request to change based on
-responses that are not fully validation could have allow at least a
-theoretical DoS attack if an attacker were to have means for injecting
-RADIUS messages to the network using the IP address of the real RADIUS
-server and being able to do so more quickly than the real server and
-with the matching identifier from the request header (i.e., either by
-flooding 256 responses quickly or by having means to capture the RADIUS
-request). These should not really be realistic options in a properly
-protected deployment, but nevertheless it is good to be more careful in
-processing RADIUS responses.
-
-Remove a pending RADIUS request from the internal list only when having
-fully accepted a matching RADIUS response, i.e., after one of the
-registered handlers has confirmed that the authenticator is valid and
-processing of the response has succeeded.

-Subject: RADIUS: Fix pending request dropping
-
-A recent change to this moved the place where the processed RADIUS
-request was removed from the pending list to happen after the message
-handler had been called. This did not take into account possibility of
-the handler adding a new pending request in the list and the prev_req
-pointer not necessarily pointing to the correct entry anymore. As such,
-some of the pending requests could have been lost and that would result
-in not being able to process responses to those requests and also, to a
-memory leak.
-
-Fix this by determining prev_req at the point when the pending request
-is being removed, i.e., after the handler function has already added a
-new entry.
-
-Fixes: 726432d7622c ("RADIUS: Drop pending request only when accepting the response")
