Pedro Monreal Gonzalez 6bc57d937f - FIPS: Deny SHA-1 signature verification in FIPS provider [bsc#1221365] 
* SHA-1 is not allowed anymore in FIPS 186-5 for signature
    verification operations. After 12/31/2030, NIST will disallow
    SHA-1 for all of its usages.
  * Add openssl-3-FIPS-Deny-SHA-1-sigver-in-FIPS-provider.patch

- FIPS: RSA keygen PCT requirements.
  * Skip the rsa_keygen_pairwise_test() PCT in rsa_keygen() as the
    self-test requirements are covered by do_rsa_pct() for both
    RSA-OAEP and RSA signatures [bsc#1221760]
  * Enforce error state if rsa_keygen PCT is run and fails [bsc#1221753]
  * Add openssl-3-FIPS-PCT_rsa_keygen.patch

- FIPS: Check that the fips provider is available before setting
  it as the default provider in FIPS mode. [bsc#1220523]
  * Rebase openssl-Force-FIPS.patch

- FIPS: Port openssl to use jitterentropy [bsc#1220523]
  * Set the module in error state if the jitter RNG fails either on
    initialization or entropy gathering because health tests failed.
  * Add jitterentropy as a seeding source output also in crypto/info.c
  * Move the jitter entropy collector and the associated lock out
    of the header file to avoid redefinitions.
  * Add the fips_local.cnf symlink to the spec file. This simlink
    points to the openssl_fips.config file that is provided by the
    crypto-policies package.
  * Rebase openssl-3-jitterentropy-3.4.0.patch
  * Rebase openssl-FIPS-enforce-EMS-support.patch

- FIPS: Block non-Approved Elliptic Curves [bsc#1221786]

From e1eba21921ceeffa45ffd2115868c14e4c7fb8d9 Mon Sep 17 00:00:00 2001

Subject: [PATCH] hmac: Add explicit FIPS indicator for key length
NIST SP 800-131Ar2, table 9 "Approval Status of MAC Algorithms"
specifies key lengths < 112 bytes are disallowed for HMAC generation and
are legacy use for HMAC verification.
Add an explicit indicator that will mark shorter key lengths as
unsupported. The indicator can be queries from the EVP_MAC_CTX object
using EVP_MAC_CTX_get_params() with the
OSSL_MAC_PARAM_SUSE_FIPS_INDICATOR
parameter.
