Brotli compression module from Google, http2, ngx_cache_purge and ngx_http_geoip2 modules are built in. OpenSSL is built dynamically using official OpenSSL 4.0.0 with QUIC support.

Major changes:

– 1.30.x stable branch.

openssl 4.0.0 rpms released

openssl 4.0.0 rpms released and added to all supported platforms (Alma Linux, Rocky Linux, Red Hat Enterprise Linux RHEL, Oracle Linux).

OpenSSL 4.0.0 is a feature release adding significant new functionality to OpenSSL. This release incorporates the following potentially significant or incompatible changes:

– Removed extra leading ’00:’ when printing key data such as an RSA modulus in hexadecimal format where the first (most significant) byte is >= 0x80. – Standardized the width of hexadecimal dumps to 24 bytes for signatures (to stay within the 80 characters limit) and 16 bytes for everything else. – Lower bounds checks are now enforced when using `PKCS5_PBKDF2_HMAC` API with FIPS provider. – Added AKID verification checks when `X509_V_FLAG_X509_STRICT` is set. – Augmented CRL verification process with several additional checks. – `libcrypto` no longer cleans up globally allocated data via `atexit()`. – `BIO_snprintf()` now uses `snprintf()` provided by libc instead of internal implementation. – `OPENSSL_cleanup()` now runs in a global destructor, or not at all by default. – `ASN1_STRING` has been made opaque. – Signatures of numerous API functions, including those that are related to X509 processing, are changed to include `const` qualifiers for argument and return types, where suitable. – Deprecated `X509_cmp_time()`, `X509_cmp_current_time()`, and `X509_cmp_timeframe()` in favor of `X509_check_certificate_times()`. – Removed support for the SSLv2 Client Hello. – Removed support for SSLv3. SSLv3 has been deprecated since 2015, and OpenSSL had it disabled by default since version 1.1.0 (2016). – Removed support for engines. The `no-engine` build option and the `OPENSSL_NO_ENGINE` macro are always present. – Support of deprecated elliptic curves in TLS according to RFC 8422 was disabled at compile-time by default. To enable it, use the `enable-tls-deprecated-ec` configuration option. – Support of explicit EC curves was disabled at compile-time by default. To enable it, use the `enable-ec_explicit_curves` configuration option. – Removed `c_rehash` script tool. Use `openssl rehash` instead. – Removed the deprecated `msie-hack` option from the `openssl ca` command. – Removed `BIO_f_reliable()` implementation without replacement. It was broken since 3.0 release without any complaints. – Removed deprecated support for custom `EVP_CIPHER`, `EVP_MD`, `EVP_PKEY`, and `EVP_PKEY_ASN1` methods. – Removed deprecated fixed SSL/TLS version method functions. – Removed deprecated functions `ERR_get_state()`, `ERR_remove_state()` and `ERR_remove_thread_state()`. The `ERR_STATE` object is now always opaque. – Dropped `darwin-i386{,-cc}` and `darwin-ppc{,64}{,-cc}` targets from Configurations. This release adds the following new features: – Support for Encrypted Client Hello (ECH, RFC 9849). See `doc/designs/ech-api.md` for details. – Support for RFC 8998, signature algorithm `sm2sig_sm3`, key exchange group `curveSM2`, and tls-hybrid-sm2-mlkem post-quantum group `curveSM2MLKEM768`. – cSHAKE function support as per SP 800-185. – “ML-DSA-MU” digest algorithm support. – Support for SNMP KDF and SRTP KDF. – FIPS self tests can now be deferred and run as needed when installing the FIPS module with the `-defer_tests` option of the `openssl fipsinstall` command. – Support for using either static or dynamic VC runtime linkage on Windows. – Support for negotiated FFDHE key exchange in TLS 1.2 in accordance with RFC 7919. RFC 8422: RFC 9849: RFC 8998: SP 800-185: RFC 7919:

.so Suffix changed from 81.3 to 81.4 (/usr/lib64/libcrypto.so.81.4.0.0, /usr/lib64/libcrypto.so.81.4 -> libcrypto.so.81.4.0.0, /usr/lib64/libssl.so.81.4.0.0, /usr/lib64/libssl.so.81.4 -> libssl.so.81.4.0.0).

We continue to build libs with QUIC support as a separate non-conflicting package openssl-quic-libs, with separate .so.81.4 suffixing to avoid conflicts with the official .so.X.

Encrypted Client Hello Comes to NGINX

We are rebuilding all the packages against openssl 4.0.0 that was released today.

Our nghttp2 (as builds test tool and httpd prerequisite) pull request was accepted some days ago, so it is no more a blocker.

Nginx 1.28.x was a blocker, but team finally released nginx 1.30 with ECH support and now all the stack builds with openssl 4.

Small exception is httpd that requires some patches to fix openssl 4 build (as api changed), it will be published as openssl4.patch in src.rpm separately.

NGINX 1.29.8 Mainline with Brotli, TLS 1.3, OpenSSL 3.5.6, HTTP/2 and HTTP/3 for Red Hat Enterprise Linux, CentOS, Rocky, Oracle, Alma Linux EL7/EL8/EL9/EL10

nginx 1.29.8 Mainline with HTTP/3 support featuring support for Multipath TCP and upgrading the default HTTP version to HTTP/1.1 with keep-alive enabled added to EL7, EL8, EL9, EL10 repositories. brotli compression module from Google, http2, ngx cache purge and ngx http geoip2 modules added or built-in. OpenSSL built dynamically using official OpenSSL 3.5.6 with QUIC support.

nginx-1.29.8 mainline version has been released featuring max_headers configuration.

    *) Feature: the "max_headers" directive.
       Thanks to Maxim Dounin.

    *) Feature: OpenSSL 4.0 compatibility.

    *) Feature: now the "include" directive inside the "geo" block supports wildcards.

    *) Bugfix: in processing of HTTP 103 (Early Hints) responses from a proxied backend.

    *) Bugfix: the $request_port and $is_request_port variables were not available in subrequests.
