The current logic did not make sure that each entry provided was
actually parsed. Also add a sanity check to make sure that no duplicate
parsing occurs.
When updating the network ranking there was a potential out of bounds
array access. The condition was if known_network_offset returned a
negative value, indicating the known network was not found. Since
network->info is only set for known networks this should not ever
happen as network->info is checked prior.
Though this is likely impossible, knownnetworks is complex enough that
its better to just be paranoid and put an L_WARN_ON to check the
return.
Since the property Autoconnect was renamed to AutoConnect, change the
Autoconnect setting to match.
For now we still allow the legacy name to be used here, but a warning is
printed to remind users to update.
Relax the pre-check for local user certificate. Before we used to check
that the CA provided (if any) was used to verify both the peer identity
and the local certificate chain. However, there seem to be networks
that use different CAs to sign AP/Radius certificates and certificates
issued to users.
Drop the ca_certs argument from l_certchain_verify, but keep the call
there to make sure the certificate chain is indeed a chain as a sanity
check.
The commit/confirm processing was incorrectly subtracting 2 from
the length when they should be subtracting 6. As with the other
similar change, the length is validated with mpdu_validate so
subtracting 6 will not cause an overflow.
This function was returning a boolean and the expected return was
a signed integer. Since this function actually returned false in
all cases the check for a success (0) return always worked.
The comment about the 'standard code path' was removed as this is
no longer valid.
If an authentication frame of length <= 5 is sent sae will overflow an
integer. The original cause of this was due to incorrectly using the
sizeof(struct mmpdu_header). The header can be either 24 or 28 bytes
depending on fc.order. sizeof does not account for this so 28 is always
the calculated length.
This, in addition to hostapd not including a group number when rejecting,
cause this erroneous length calculation to be worked around as seen in
the removed comment. The comment is still valid (and described again
in another location) but the actual check for len == 4 is not correct.
To fix this we now rely on mpdu_validate to check that the authentication
frame is valid, and then subtract the actual header length using
mmpdu_header_len rather than sizeof. Doing this lets us also remove the
length check since it was validated previously.
