End +users have been advised to migrate to the new Provider interface. +Several distributions have already removed support for engines, which is +preventing U-Boot from being compiled in those environments. + +Add support for the Provider API while continuing to support the existing +Engine API on distros shipping older releases of OpenSSL. + +This is based on similar work contributed by Jan Stancek updating Linux +to use the Provider interface. + + commit 558bdc45dfb2669e1741384a0c80be9c82fa052c + Author: Jan Stancek + Date: Fri Sep 20 19:52:48 2024 +0300 + + sign-file,extract-cert: use pkcs11 provider for OPENSSL MAJOR >= 3 + +The changes have been tested with the FIT signature verification vboot +tests on Fedora 42 and Debian 13. All 30 tests pass with both the legacy +Engine library installed and with the Provider API. + +Signed-off-by: Eddie Kovsky + +Upstream-Status: Backport [https://github.com/u-boot/u-boot/pull/918] +Signed-off-by: Jaipaul Cheernam +--- + lib/aes/aes-encrypt.c | 4 +- + lib/rsa/rsa-sign.c | 102 +++++++++++++++++++++++++++++++++++++++--- + 2 files changed, 100 insertions(+), 6 deletions(-) + +diff --git a/lib/aes/aes-encrypt.c b/lib/aes/aes-encrypt.c +index 90e1407b4f09..4fc4ce232478 100644 +--- a/lib/aes/aes-encrypt.c ++++ b/lib/aes/aes-encrypt.c +@@ -16,7 +16,9 @@ + #include + #include + #include +-#include ++#if !defined(OPENSSL_NO_ENGINE) && !defined(OPENSSL_NO_DEPRECATED_3_0) ++# include ++#endif + #include + + #if OPENSSL_VERSION_NUMBER >= 0x10000000L +diff --git a/lib/rsa/rsa-sign.c b/lib/rsa/rsa-sign.c +index 0e38c9e802fd..f456f3c58e65 100644 +--- a/lib/rsa/rsa-sign.c ++++ b/lib/rsa/rsa-sign.c +@@ -19,7 +19,47 @@ + #include + #include + #include +-#include ++#if OPENSSL_VERSION_MAJOR >= 3 ++# define USE_PKCS11_PROVIDER ++# include ++# include ++# include ++#else ++# if !defined(OPENSSL_NO_ENGINE) && !defined(OPENSSL_NO_DEPRECATED_3_0) ++# define USE_PKCS11_ENGINE ++# include ++# endif ++#endif ++ ++#ifdef USE_PKCS11_PROVIDER ++#define ERR(cond, fmt, ...) \ ++ do { \ ++ bool __cond = (cond);
