Package: openssh-client Version: 1:8.1p1-1 Severity: normal For some time now, ssh (openssh-client) unnecessarily warns for:
> invalid attribute length > failed to fetch key when SSH'ing to a host with libsimple-tpm-pk11.so as PKCS11Provider. Relevant lines from a verbose connection: $ ssh -vvv -oPKCS11Provider=libsimple-tpm-pk11.so ssh.example.com … debug1: Connecting to (…) debug1: Connection established. debug1: provider libsimple-tpm-pk11.so: manufacturerID <simple-tpm-pk11 manufacturer> cryptokiVersion 0.1 libraryDescription <simple-tpm-pk11 library> libraryVersion 0.1 debug1: provider libsimple-tpm-pk11.so slot 0: label <Simple-TPM-PK11 token> manufacturerID <manuf id> model <model> serial <serial> flags 0x400 debug1: have 1 keys invalid attribute length failed to fetch key … debug1: Will attempt key: libsimple-tpm-pk11.so RSA SHA256:(xxx-hash-of-my-tpm-key-xxx) token … This was initially reported at https://github.com/ThomasHabets/simple-tpm-pk11/issues/48, and brought to Fedora: https://bugzilla.redhat.com/show_bug.cgi?id=1710832, which fixed it. Perhaps it also needs fixing in simple-tpm-pk11, but let's start with a bugreport where the warning is emitted.
