8b423edbd3 Declare all read only data structures as const
By analysing objdump output some read only structures were found in
.data section. To help compiler further optimize code declare these
as const.

02a8d45ace ERP: Add support for ERP on EAP peer
Derive rRK and rIK on EAP peer if ERP is enabled. The new wpa_supplicant
network configuration parameter erp=1 can now be used to configure the
EAP peer to derive EMSK, rRK, and rIK at the successful completion of an
EAP authentication method. This functionality is not included in the
default build and can be enabled with CONFIG_ERP=y.

If EAP authenticator indicates support for re-authentication protocol,
initiate this with EAP-Initiate/Re-auth and complete protocol when
receiving EAP-Finish/Re-auth.

27a725cf74 EAP: Do not allow fast session resumption with different network block
This forces EAP peer implementation to drop any possible fast resumption
data if the network block for the current connection is not the same as
the one used for the previous one. This allows different network blocks
to be used with non-matching parameters to enforce different rules even
if the same authentication server is used. For example, this allows
different CA trust rules to be enforced with different ca_cert
parameters which can prevent EAP-TTLS Phase 2 from being used based on
TLS session resumption.

c60ba9f7ab Skip network disabling on expected EAP failure
Some EAP methods can go through a step that is expected to fail and as
such, should not trigger temporary network disabling when processing
EAP-Failure or deauthentication. EAP-WSC for WPS was already handled as
a special case, but similar behavior is needed for EAP-FAST with
unauthenticated provisioning.

a5d44ac083 EAP peer: Add framework for external SIM/USIM processing
The new configuration parameter external_sim=<0/1> can now be used to
configure wpa_supplicant to use external SIM/USIM processing (e.g., GSM
authentication for EAP-SIM or UMTS authentication for EAP-AKA). The
requests and responses for such operations are sent over the ctrl_iface
CTRL-REQ-SIM and CTRL-RSP-SIM commands similarly to the existing
password query mechanism.

Changes to the EAP methods to use this new mechanism will be added in
separate commits.

950c563076 EAP peer: Add Session-Id derivation
This adds a new getSessionId() callback for EAP peer methods to allow
EAP Session-Id to be derived. This commits implements this for EAP-FAST,
EAP-GPSK, EAP-IKEv2, EAP-PEAP, EAP-TLS, and EAP-TTLS.

0ebb23e340 EXT PW: Add support for password parameter from external storage
This allows the password parameter for EAP methods to be fetched
from an external storage.

Following example can be used for developer testing:

ext_password_backend=test:pw1=password|pw2=testing

network={
    key_mgmt=WPA-EAP
    eap=TTLS
    identity="user"
    password=ext:pw1
    ca_cert="ca.pem"
    phase2="auth=PAP"
}

9f98810c5d TLS: Use separate TLS library context for tunneled TLS
OpenSSL wrapper was using the same certificate store for both Phase 1
and Phase 2 TLS exchange in case of EAP-PEAP/TLS, EAP-TTLS/TLS, and
EAP-FAST/TLS. This would be fine if the same CA certificates were used
in both phases, but does not work properly if different CA certificates
are used. Enforce full separation of TLS state between the phases by
using a separate TLS library context in EAP peer implementation.

f2d8fc3d96 Do not try session resumption after EAP failure
If session resumption fails for any reason, do not try it again because
that is just likely to fail. Instead, drop back to using full
authentication which may work. This is a workaround for servers that do
not like session resumption, but do not know how to fall back to full
authentication properly.

000a1de72b Cleaned up EAP-MSCHAPv2 key derivation
Changed peer to derive the full key (both MS-MPPE-Recv-Key and
MS-MPPE-Send-Key for total of 32 octets) to match with server
implementation.

Swapped the order of MPPE keys in MSK derivation since server
MS-MPPE-Recv-Key | MS-MPPE-Send-Key matches with the order specified for
EAP-TLS MSK derivation. This means that PEAPv0 cryptobinding is now
using EAP-MSCHAPv2 MSK as-is for ISK while EAP-FAST will need to swap
the order of the MPPE keys to get ISK in a way that interoperates with
Cisco EAP-FAST implementation.

116654ce24 WPS: Moved wps_context initialization into wps_supplicant.c
The wps_context data is now managed at wpa_supplicant, not EAP-WSC. This
makes wpa_supplicant design for WPS match with hostapd one and also
makes it easier configure whatever parameters and callbacks are needed
for WPS.
