OpenConnect 7.00 release

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

 



Lots of fun stuff here, especially on Windows. We now support keys from
the Windows certificate store, and the new NDIS6 TAP-Windows driver. And
should run on systems as far back as Windows XP.

In order to simplify string ownership rules and reduce the likelihood of
bugs, and to cope with restrictions that Windows 'DLL Hell' imposes, the
API has been completely changed so that strings do not change ownership
when they are passed into the library. API functions take 'const char *'
and will take a *copy* of the string if appropriate. The soname of the
library is bumped accordingly.

This release adds full Unicode handling for both Windows and legacy
non-UTF-8 POSIX platforms. All strings passed into, or out of, the
libopenconnect library should now be UTF-8 and it is the responsibility
of the application if running in a legacy environment to do any
conversions that are necessary.

The utun driver on OS X is now supported, so it's no longer necessary to
install a third-party unsigned kernel module.

OATH HOTP/TOTP keys stored in a Yubikey NEO using the ykneo-oath applet
are also now supported. Tested on OSX, Windows and Linux. Software HOTP
token support is now capable of using a token from a PSKC file and
updating the token counter therein, thus making it actually *useful*.

Thread-safety issues caused by using setenv()/putenv() within the
library have now been fixed.

A --no-system-trust option has been added, to prevent OpenConnect from
trusting any certificate authorities apart from those explicitly passed
to it with the --cafile option. Corresponding library APIs also exist.

Thanks to Nikos Mavrogiannopoulos and Kevin Cernekee in particular for
their significant contributions to this release. Their Android and
Windows clients are a major factor in continued improvements.
