Hello Adam, I tried to apply your patch after updating to the latest upstream release, but the patch is not merged, and doesn't apply anymore. You say it comes from upstream, but Debian upstream repo is tracked at git://git.infradead.org/users/dwmw2/openconnect.git
So please update the patch for the newer version and make sure upstream applies it, in order to drop on the next release thanks Gianfranco
