The asymmetric crypto capability structure currently reports only a generic modulus length and primary hash algorithm for RSA, with no way for a PMD to advertise which padding schemes (NONE, PKCS#1 v1.5, OAEP, PSS) or MGF1 hash algorithms it supports. Applications have no standard way to discover this, and the OpenSSL PMD itself only implements NONE and PKCS#1 v1.5 padding.
This series first extends the capability API with a dedicated rte_crypto_rsa_capa (modulus length, pad_types, mgf1_hash_algos, and an explicit-PSS-salt flag), then updates the capability reporting in the virtio, octeontx, cnxk, qat, and openssl PMDs to use it. On top of that, it adds actual RSA-OAEP and RSA-PSS support to the OpenSSL PMD: - RSA-OAEP encrypt/decrypt, with configurable OAEP hash, MGF1 hash, and an optional label, defaulting MGF1 to the OAEP hash when unset. - RSA-PSS sign/verify, with configurable hash, MGF1 hash, and salt length (rte_crypto_rsa_padding::pss_saltlen), using a dedicated EVP_PKEY_verify()-based verification path since PSS does not support verify-recover. The PSS salt itself is always generated internally by the PMD; an application-supplied salt (rte_crypto_rsa_op_param::pss_salt, gated by the new pss_explicit_salt capability bit) is introduced by this series for future PMD support but is not yet implemented here, so it is rejected with RTE_CRYPTO_OP_STATUS_INVALID_ARGS. Test coverage for both OAEP (encrypt/decrypt, default and custom MGF1, with and without a label) and PSS (digest-length, maximum, and zero-length salt) is added to the cryptodev asymmetric test suite.
