2efa60344e PASN: Encode the public key properly
When a public key is included in the PASN Parameters element, it should
be encoded using the RFC 5480 conventions, and thus the first octet of
the Ephemeral Public Key field should indicate whether the public key is
compressed and the actual key part starts from the second octet.

Fix the implementation to properly adhere to the convention
requirements for both wpa_supplicant and hostapd.

cd0813763a PASN: Include PMKID in RSNE in PASN response from AP
As defined in IEEE P802.11az/D3.0, 12.12.3.2 for the second PASN frame.
This was previously covered only for the case when the explicit PMKSA
was provided to the helper function. Extend that to cover the PMKID from
SAE/FILS authentication cases.

c733664be9 EAP peer: Make EAP-Success handling more robust against race conditions
When ERP initialization was moved from the METHOD state to the SUCCESS
state, the conditions for checking against EAP state being cleared was
missed. The METHOD state verified that sm->m is not NULL while the
SUCCESS state did not have such a check. This opened a window for a race
condition where processing of deauthentication event and EAPOL RX events
could end up delivering an EAP-Success to the EAP peer state machine
after the state had been cleared. This issue has now been worked around
in another manner, but the root cause for this regression should be
fixed as well.

Check that the EAP state machine is properly configured before trying to
initialize ERP in the SUCCESS state.

a0541334a6 ASN.1: Validate DigestAlgorithmIdentifier parameters
The supported hash algorithms do not use AlgorithmIdentifier parameters.
However, there are implementations that include NULL parameters in
addition to ones that omit the parameters. Previous implementation did
not check the parameters value at all which supported both these cases,
but did not reject any other unexpected information.

Use strict validation of digest algorithm parameters and reject any
unexpected value when validating a signature. This is needed to prevent
potential forging attacks.

constructed to get the hash value from after the actual DigestInfo

ee76493bbd ASN.1: Reject invalid definite long form length values in DER encoding
The definite long form for the length is allowed only for cases where
the definite short form cannot be used, i.e., if the length is 128 or
greater. This was not previously enforced and as such, multiple
different encoding options for the same length could have been accepted.

Perform more strict checks to reject invalid cases for the definite long
form for the length. This is needed for a compliant implementation and
this is especially important for the case of verifying DER encoded
signatures to prevent potential forging attacks.

3af75f23b0 ASN.1: Reject invalid extended tags in DER encoding
The extended tag case is allowed only for tag values that are 31 or
larger (i.e., the ones that would not fit in the single octet identifier
case with five bits). Extended tag format was previously accepted even
for the values 0..31 and this would enable multiple different encodings
for the same tag value. That is not allowed for DER.

Perform more strict checks to reject invalid extended tag values. This
is needed for a compliant implementation and this is especially
important for the case of verifying DER encoded signatures to prevent
potential forging attacks.

The identifier octet in DER encoding includes three components. Only two
of these (Class and Tag) were checked in most cases when looking for a
specific data type. Also check the Primitive/Constructed bit to avoid
accepting invalid encoding.

This is needed for correct behavior in DER parsing and especially
important for the case of verifying DER encoded signatures to prevent
potential forging attacks.

82a348eda4 wpa_supplicant: Don't process EAPOL frames while disconnecting
An EAPOL frame may be pending when wpa_supplicant requests to
deauthenticate. At this stage the EAP SM cache is already cleaned by
calling eapol_sm_invalidate_cached_session(). Since at this stage the
wpa_supplicant's state is still set to associated, the EAPOL frame is
processed and results in a crash due to NULL dereference.

This wasn't seen previously as nl80211 wouldn't process the
NL80211_CMD_CONTROL_PORT_FRAME, since wpa_driver_nl80211_mlme() would
set the valid_handler to NULL. This behavior was changed in commit
ab89291928 exposing this race.

Fix it by ignoring EAPOL frames while the deauthentication is in
progress.
