224104ddf6 TLS: Reject openssl_ciphers parameter in non-OpenSSL cases
This TLS configuration parameter is explicitly for OpenSSL. Instead of
ignoring it silently, reject any configuration trying to use it in
builds that use other options for TLS implementation.

f8717ac8b3 GnuTLS: Reject subject_match, altsubject_match, suffix_match
Validation of these parameters has not been implemented with GnuTLS.
Instead of ignoring them silently, reject the configuration to avoid
giving incorrect impression of the parameters being used if
wpa_supplicant is built with GnuTLS instead of the default OpenSSL.

7d9286d3e7 Support private_key_passwd for GnuTLS (3.1.11+)
It's possible to jump through hoops to support it in older versions too,
but that seems a little unnecessary at this point.

cbe23ffd6d GnuTLS: Get rid of warnings about deprecated typedef names
'_t' suffix for gnutls_session and gnutls_transport_ptr was added in
GnuTLS 1.1.11 over ten years ago and the more recent versions of GnuTLS
have started forcing compiler warnings from the old names. Move to the
new names and don't bother about backwards compatibility with older
versions taken into account how long ago this change happened in GnuTLS.

0187c41d88 Declare wpa_debug_* variables in src/utils/wpa_debug.h
These were somewhat more hidden to avoid direct use, but there are now
numerous places where these are needed and more justification to make
the extern int declarations available from wpa_debug.h. In addition,
this avoids some warnings from sparse.

fd2f2d0489 Remove EAP-TTLSv1 and TLS/IA
These protocols seem to be abandoned: latest IETF drafts have expired
years ago and it does not seem likely that EAP-TTLSv1 would be
deployed. The implementation in hostapd/wpa_supplicant was not complete
and not fully tested. In addition, the TLS/IA functionality was only
available when GnuTLS was used. Since GnuTLS removed this functionality
in 3.0.0, there is no available TLS/IA implementation in the latest
version of any supported TLS library.

Remove the EAP-TTLSv1 and TLS/IA implementation to clean up unwanted
complexity from hostapd and wpa_supplicant. In addition, this removes
any potential use of the GnuTLS extra library.

2944656925 Allow TLS flags to be configured (allow MD5, disable time checks)
Undocumented (at least for the time being) TLS parameters can now
be provided in wpa_supplicant configuration to enable some workarounds
for being able to connect insecurely to some networks. phase1 and
phase2 network parameters can use following options:
tls_allow_md5=1
- allow MD5 signature to be used (disabled by default with GnuTLS)
tls_disable_time_checks=1
- ignore certificate expiration time

For now, only the GnuTLS TLS wrapper implements support for these.

81c85c069a Convert TLS wrapper to use struct wpabuf
This converts tls_connection_handshake(),
tls_connection_server_handshake(), tls_connection_encrypt(), and
tls_connection_decrypt() to use struct wpa_buf to allow higher layer
code to be cleaned up with consistent struct wpabuf use.

edd757e8a3 Use larger buffer for TLS encryption to avoid issues with GnuTLS
It looks like GnuTLS (at least newer versions) is using random padding
on the application data and the previously used 100 byte extra buffer
for tls_connection_encrypt() calls was not enough to handle all cases.
This resulted in semi-random authentication failures with EAP-PEAP and
EAP-TTLS during Phase 2.

Increase the extra space for encryption from 100 to 300 bytes and add an
error message into tls_gnutls.c to make it easier to notice this issue
should it ever show up again even with the larger buffer.
