I usually build my kernels to require module signatures and use automatic signing. As of v4.6-rc1 I'm getting this on boot: Problem loading in-kernel X.509 certificate (-2) I bisected that to commit d43de6c780a84def056afaf4fb3e66bdaa1efc00 (akcipher: Move the RSA DER encoding check to the crypto layer) For some reason after this commit my system keyring always ends up empty. I use the deb-pkg make target. My kernel config can be found at http://audible.transient.net/~jamie/k/modsign.config-4.6.0-rc5-guest Let me know if you need anything else. -- Jamie Heilman http://audible.transient.net/~jamie/ -- To unsubscribe from this list: send the line "unsubscribe linux-crypto" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
