Ehm, maybe not. As Jason points out, the typedef does not have quite the right type, so that is most likely the culprit, and this workaround would trigger CFI in exactly the same way. Interestingly, the compiler does not seem to mind, right? Or are you seeing any build time warnings on the reference to blake2s_compress in the call to __blake2s_update() ?
No, no warnings as the -Wcast-function-type is globally enabled. I cleaned some cast-function-type errors but no warnings in __blake2s_update.
