Commit 63ba4d67594a ("KEYS: asymmetric: Use new crypto interface without scatterlists") converted the sole user in the tree to the new API. Although the API externally accepts kernel buffers, internally it still converts them to sglists, which results in overhead for asymmetric algorithms because they need to copy the sglists back into kernel buffers. Take the next step and switch signature verification over to using kernel buffers internally, thereby avoiding the sglists overhead. Because all ->verify implementations are synchronous, forego invocation of crypto_akcipher_sync_{prep,post}() and call crypto_akcipher_verify() directly from crypto_sig_verify().

Miller" , Stefan Berger Cc: David Howells , Vitaly Chikunov , Tadeusz Struk , Andrew Zaborowski , Saulo Alessandre , Jonathan Cameron , linux-crypto@vger.kernel.org, keyrings@vger.kernel.org Precedence: bulk X-Mailing-List: linux-crypto@vger.kernel.org List-Id: List-Subscribe: List-Unsubscribe: When extracting a signature component r or s from an ASN.1-encoded integer, ecdsa_get_signature_rs() subtracts the expected length "bufsize" from the ASN.1 length "vlen" (both of unsigned type size_t) and stores the result in "diff" (of signed type ssize_t). This results in a signed integer overflow if vlen > SSIZE_MAX + bufsize. The kernel is compiled with -fno-strict-overflow, which implies -fwrapv, meaning signed integer overflow is not undefined behavior. And the function does check for overflow: if (-diff >= bufsize) return -EINVAL; So the code is fine in principle but not very obvious. In the future it might trigger a false-positive with CONFIG_UBSAN_SIGNED_WRAP=y. Avoid by comparing the two unsigned variables directly and erroring out if "vlen" is too large.

Miller" , Stefan Berger Cc: David Howells , Vitaly Chikunov , Tadeusz Struk , Andrew Zaborowski , Saulo Alessandre , Jonathan Cameron , linux-crypto@vger.kernel.org, keyrings@vger.kernel.org Precedence: bulk X-Mailing-List: linux-crypto@vger.kernel.org List-Id: List-Subscribe: List-Unsubscribe: Unlike the rsa driver, which separates signature decoding and signature verification into two steps, the ecdsa driver does both in one. This restricts users to the one signature format currently supported (X9.62) and prevents addition of others such as P1363, which is needed by the forthcoming SPDM library (Security Protocol and Data Model) for PCI device authentication. Per Herbert's suggestion, change ecdsa to use a "raw" signature encoding and then implement X9.62 and P1363 as templates which convert their respective encodings to the raw one. One may then specify "x962(ecdsa-nist-XXX)" or "p1363(ecdsa-nist-XXX)" to pick the encoding. The present commit moves X9.62 decoding to a template. A separate commit is going to introduce another template for P1363 decoding. The ecdsa driver internally represents a signature as two u64 arrays of size ECC_MAX_BYTES. This appears to be the most natural choice for the raw format as it can directly be used for verification without having to further decode signature data or copy it around. Repurpose all the existing test vectors for "x962(ecdsa-nist-XXX)" and create a duplicate of them to test the raw encoding.

References: From: Lukas Wunner Date: Mon, 29 Jul 2024 15:51:00 +0200 Subject: [PATCH 5/5] crypto: ecdsa - Support P1363 signature decoding To: Herbert Xu , "David S. Miller" , Stefan Berger Cc: David Howells , Vitaly Chikunov , Tadeusz Struk , Andrew Zaborowski , Saulo Alessandre , Jonathan Cameron , linux-crypto@vger.kernel.org, keyrings@vger.kernel.org Precedence: bulk X-Mailing-List: linux-crypto@vger.kernel.org List-Id: List-Subscribe: List-Unsubscribe: Alternatively to the X9.62 encoding of ecdsa signatures, which uses ASN.1 and is already supported by the kernel, there's another common encoding called P1363. It stores r and s as the concatenation of two big endian, unsigned integers. The name originates from IEEE P1363. Add a P1363 template in support of the forthcoming SPDM library (Security Protocol and Data Model) for PCI device authentication. P1363 is prescribed by SPDM 1.2.1 margin no 44: "For ECDSA signatures, excluding SM2, in SPDM, the signature shall be the concatenation of r and s. The size of r shall be the size of the selected curve. Likewise, the size of s shall be the size of the selected curve. See BaseAsymAlgo in NEGOTIATE_ALGORITHMS for the size of r and s. The byte order for r and s shall be in big endian order. When placing ECDSA signatures into an SPDM signature field, r shall come first followed by s."
