Better sooner than later, thanks for the report. > If we make the hook generic, extension authors must have a way to tell which > backend invoked it, so maybe the best option is to simply wrap this hook in > USE_OPENSSL ifdefs and keep the name/signature?

I agree that this looks like an oversight of the original commit introducing the hook as it gets called in the OpenSSL code path of be_tls_init(), so I think that your patch is right (though I would have just used #ifdef USE_OPENSSL here). And if the future proves that this hook has more uses for other SSL implementations, we could always rework it at this point, if necessary. Andrew, would you prefer fixing that yourself? -- Michael
