OpenConnect 3.99 release (4.00 beta)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This is a prerelease of v4.00 to get a little more testing.

The main thing it does is add GnuTLS support. It supports PKCS#11 crypto
tokens, and also TPM keys. Thanks to Carolin Latze for the TPM support,
and especially to Nikos Mavrogiannopoulos for a lot of other help in
getting GnuTLS working, including DTLS support.

It still uses OpenSSL by default, unless you pass '--with-gnutls' on the
configure command line. If you aren't using a version of GnuTLS which
supports Cisco-DTLS, it'll still fall back to using OpenSSL for that,
while using GnuTLS for the HTTPS part.

Places where the library used to expose an OpenSSL 'X509' structure now
expose a generic pointer. It *might* be an X509, or it might be a
gnutls_x509_crt_t. There are functions to do various operations on it
(fingerprint, pretty-print as text) that the auth-dialogs were doing,
and a function to export it in DER form if an auth-dialog wants to do
something more advanced. All the callbacks for user interaction are also
cleaned up to use the ->process_auth_form() method, so auth-dialogs no
longer need to capture the OpenSSL UI method calls.

Note that TPM support is only available with GnuTLS 3.x; if you're stuck
on GnuTLS 2.12 then please file a bug with your Linux distribution to
get it updated. GnuTLS 3.0 was released almost a year ago! Other
functionality is subtly substandard when used with GnuTLS 2.12 too.

This release also also adds a $CISCO_SPLIT_DNS variable when invoking
vpnc-script, with a comma-separated list of search domains. (Patches to
vpnc-script welcome; NetworkManager is already updated.)

Finally it improves the MTU configuration to improve connectivity with
new servers by allowing different MTU for CSTP and DTLS connections.
Although it's not clear how Cisco's scheme for this is intended to work;
it looks like it'd work a lot better if their server didn't give an
artificially low MSS when accepting the TCP connection.

Oh, and the --cert-type option is gone from the command line. We've been
automatically detecting that for a *long* time, so the option was
unneeded.
