p2p_add_device() may remove the oldest entry if there is no room in the
peer table for a new peer. This would result in any pointer to that
removed entry becoming stale. A corner case with an invalid PD Request
frame could result in such a case ending up using (read+write) freed
memory. This could only by triggered when the peer table has reached its
maximum size and the PD Request frame is received from the P2P Device
Address of the oldest remaining entry and the frame has incorrect P2P
Device Address in the payload.
Fix this by fetching the dev pointer again after having called
p2p_add_device() so that the stale pointer cannot be used.

Reordering of code in handle_auth_cb() when adding support for full
station state messaged up frame length checks. The length was originally
tested before looking at the payload of the frame and that is obviously
the correct location for that check. The location after those full state
state changes was after having read six octets of the payload which did
not help at all since there was no addition accesses to the payload
after that check.
Move the payload length check to appropriate place to get this extra
level of protection behaving in the expected manner. Since this is a TX
status callback handler, the frame payload is from a locally generated
Authentication frame and as such, it will be long enough to include
these fields in production use cases. Anyway, better keep this check in
working condition.

EAP peer does not expect data present when beginning the Phase 2 in
EAP-{TTLS,PEAP} but in TLS 1.3 session tickets are sent after the
handshake completes.
There are several strategies that can be used to handle this, but this
patch picks up from the discussion[1] and implements the proposed use of
SSL_MODE_AUTO_RETRY. SSL_MODE_AUTO_RETRY has already been enabled by
default in OpenSSL 1.1.1, but it needs to be enabled for older versions.
The main OpenSSL wrapper change in tls_connection_decrypt() takes care
of the new possible case with SSL_MODE_AUTO_RETRY for
SSL_ERROR_WANT_READ to indicate that a non-application_data was
processed. That is not really an error case with TLS 1.3, so allow it to
complete and return an empty decrypted application data buffer.
EAP-PEAP/TTLS processing can then use this to move ahead with starting
Phase 2.

equal. This method fails to detect if the buffer has actually been

It was not easily possible to separate configuration of an interface and
credentials when using the configuration file instead of the control
interface or D-Bus interface for setting up the network profiles. This
makes it hard to distribute configuration across a set of nodes which
use wpa_supplicant without also having to store credentials in the same
file. While this can be solved via scripting, having a native way to
achieve this would be preferable.
Turns out there already is a framework to have external password
storages. It only had a single "test" backend though, which is kind of
an in-memory store which gets initialized with all passwords up front
and is mainly for testing purposes. This isn't really suitable for the
above use case: the backend cannot be initialized as part of the central
configuration given that it needs the credentials, and we want to avoid
scripting.
This commit thus extends the infrastructure to implement a new backend,
which instead uses a simple configuration file containing key-value
pairs. The file follows the format which wpa_supplicant.conf(5) uses:
empty lines and comments are ignored, while passwords can be specified
with simple `password-name=password-value` assignments.
With this new backend, splitting up credentials and configuration
becomes trivial:
# /etc/wpa_supplicant/wpa_supplicant.conf
ext_password_backend=file:/etc/wpa_supplicant/psk.conf
network={
ssid="foobar"
psk=ext:foobar
}
# /etc/wpa_supplicant/psk.conf
foobar=ecdabff9c80632ec6fcffc4a8875e95d45cf93376d3b99da6881298853dc686b
Alternative approaches would be to support including other configuration
files in the main configuration, such that common configuration and
network declarations including credentials are split up into separate
files. But the implementation would probably have been more complex
compared to reusing the already-existing framework for external password
backends.

At least the ACS case of an attempt to pick a 40 MHz channel on the 2.4
GHz band could fail if HE was enabled and the driver did not include
support for 40 MHz channel bandwidth on the 2.4 GHz band in HE
capabilities. This resulted in "40 MHz channel width is not supported in
2.4 GHz" message when trying to configure the channel and failure to
start the AP.
Avoid this by automatically falling back to using 20 MHz bandwidth as
part of channel parameter determination at the end of the ACS procedure.

When auto channel selection (ACS) is used for HE 40 MHz in the 2.4 GHz
band, AP sets center frequency after finding a 40 MHz channel and then
runs a scan for overlapping BSSes in neighboring channels. Upon OBSS
detection, AP should downgrade to 20 MHz bandwidth.
This was broken because allowed_ht40_channel_pair() returns true in this
case and the steps to reset center frequency are not executed causing
failure to bring interface up.
Fix the condition to allow rollback to 20 MHz.
