  Changed paths:
    M crypto/dh/dh_check.c
    M crypto/dsa/dsa_check.c
    M crypto/ffc/ffc_key_validate.c
    M providers/implementations/keymgmt/dh_kmgmt.c
    M test/ffc_internal_test.c

  Log Message:
  -----------
  DH_check_pub_key() should not fail when setting result code

The semantics of ossl_ffc_validate_public_key() and
ossl_ffc_validate_public_key_partial() needs to be changed
to not return error on non-fatal problems.

Fixes #22287
