Since we cannot at this point cache names of the keys given limitations
of the ASN.1 file format, I'll start a fresh patch set. Let's fixup what
we can right now.

This patch set addresses two major issues in the feature:

1. Dynamic resolution without gain. All kernel sites have at most single
   handle to authorize. Even if this changes some day this is how it is
   as of today and we definitely do not want to dictate the future but
   instead downscale code to the metrics that we have as of today.
2. Eliminate at least one unnnecessary tpm2_read_public() call.

Jarkko Sakkinen (7):
  KEYS: trusted: Remove dead branch from tpm2_unseal_cmd
  tpm2-sessions: Define TPM2_NAME_MAX_SIZE
  KEYS: trusted: Re-orchestrate tpm2_read_public() calls
  tpm2-sessions: Remove AUTH_MAX_NAMES
  tpm-buf: Remove tpm_buf_append_handle
  tpm: Orchestrate TPM commands in tpm_get_random()
  tpm: Send only one TPM command per hwrng request
