[opensuse-buildservice] Issue with RSA signing in openSUSE:Factory:RISCV
At least since 2020-08-09 RSA signing of kernel modules is broken in openSUSE:Factory:RISCV, producing bad signatures that cannot be verified against the included certificate: $ modsign-verify -v -v --cert-dir etc/uefi/certs sunrpc.ko Signature type: pkcs#7 Signed by: cn=openSUSE Secure Boot CA,serial=1 Hash algorithm: sha256 Trying etc/uefi/certs/188EA6FA.crt Found matching certificate etc/uefi/certs/188EA6FA.crt RSA operation error 140060768991040:error:0407008A:rsa routines:RSA_padding_check_PKCS1_type_1:invalid padding:crypto/rsa/rsa_pk1.c:67: 140060768991040:error:04067072:rsa routines:rsa_ossl_public_decrypt:padding check failed:crypto/rsa/rsa_ossl.c:648: sunrpc.ko: signature validation failed for etc/uefi/certs/188EA6FA.crt sunrpc.ko: bad signature IIUC the signature appears to be created with a private key that doesn't match the public key in etc/uefi/certs/188EA6FA.crt. Since the problem does not occur if the same kernel is built in a different project, there is no fundamental problem with signature creation or verification. The last working kernel was built on 2020-08-01 in o:F:RISCV (which verifies properly using the same certificate). I note that the certificate has a serial number of 1. Isn't that serial number supposed to be unique?

Still broken.

Still broken, unfortunately.

Still broken, unfortunately.
and it remains that way until the internal discussion about the official
openSUSE project governance has been finished.
But I will push again...

Any news?

Next builds will use openSUSE signatures and ssl cert now.

Thanks, I can confirm that the kernel is no longer broken.
