The Apache Tomcat Native Library 1.3 - Miscellaneous Documentation

This is the Changelog for Tomcat Native 1.3.x. The Tomcat Native 1.3.x branch started from the 1.2.39 tag.

• Remove call to ERR_remove_thread_state() from Windows specific code to allow building with OpenSSL 4.0.x. ERR_remove_thread_state() is a no-op in OpenSSL 1.1+ and got removed in OpenSSL 4. (rjung)
• Fix a potential crash when negotiating ALPN. (markt)
• If ALPN negotiation fails and failure is configured to use the last server protocol in the list, use it rather than the last protocol offered by the client. (markt)
• Add support for the extended range of options available from OpenSSL 3.0.x. The options flag is now a 64-bit unsigned int (represented by a Java long) rather than a 32-bit unsigned int (represented by a Java int). (markt)
• Remove unused code. (markt)
• Ensure that per connection changes to certificate verification settings, e.g. to support client certificate authentication, do not modify the certificate verification settings for other connections. (markt)
• Fix a potential crash when configuring raw certificates. (markt)
• Avoid a potential crash with very long ALPN protocol names. (markt)
• Make the call to a CertificateVerifier more robust. (markt)
• Avoid a potential crash when processing OCSP URLs. (markt)
• Make the processing of OCSP responses more robust. (markt)
• Stricter OCSP handling when soft-fail is disabled. (markt)
• Harden against the mis-use of Buffer.address(ByteBuffer). (markt)
• Harden against the mis-use of Pool.destroy(long). (markt)
• The minimum supported OpenSSL version is now 3.0.x. OpenSSL 1.1.1 support was accidentally broken in 1.3.8. As no bug reports were receive for that failure and since both Debian and Ubuntu versions that used OpenSSL 1.1.1 have reached end of support, OpenSSL 1.1.1 is no longer supported. (markt)
• OpenSSL 3.0.x is approaching end of support so the recommended version of OpenSSL (and the version that windows binaries will be built with) now follows the 3.5.x LTS branch. (markt)
• Switch to automatic configuration of DH parameters. Manual configuration attempts will be ignored. (markt)
• Make setTmpECDHByCurveName() a NO-OP. (markt)
• Refactor extraction of ECDH curve name from the Certificate to avoid deprecated OpenSSL methods. (markt)
• Refactor the native implementation of SSL.getTime() to avoid the Y2038 problem in SSL_SESSION_get_time() when running on a verion of OpenSSL that includes the new SSL_SESSION_get_time_ex() method. (markt)

• Fix a memory leak when parsing certificates. Pull request #44 provided by chenjp. (markt)
• Fix two potential memory leaks on error paths identified by Copilot. (markt)
• 69988: Fix post handshake authentication when Tomcat is configured with a trust store using JSSE style configuration. (markt)
• 70102: Correct expected size of tickets when calling SSLContext.setSessionTicketKeys. (markt)

• Refactor access to ASN1_OCTET_STRING to use setters to fix errors when building against the latest OpenSSL 4.0.x code. (markt)
• Fix the handling of OCSP requests with multiple responder URIs. (jfclere)
• Fix the handling of TRY_AGAIN responses to OCSP requests when soft fail is disabled. (jfclere)

• Refactor the SSL_CONF_CTX clean-up to align it with SSL and SSL_CTX clean-up. (markt)
• Fix unnecessarily large buffer allocation when filtering out NULL and export ciphers. Pull requests #35 and #37 provided by chenjp. (markt)
• Fix a potential memory leak if an invalid OpenSSLConf is provided. Pull request #36 provided by chenjp. (markt)
• Refactor setting of OCSP configuration defaults as they were only applied if the SSL_CONF_CTX was used. While one was always used with Tomcat versions aware of the OCSP configuration options, one was not always used with Tomcat versions unaware of the OCSP configuration options leading to OCSP verification being enabled by default when the expected behaviour was disabled by default. (markt)
• Improve performance for the rare case of handling large OCSP responses. (markt)

• Remove group write permissions from the files in the tar.gz source archive. (markt)
• Clear an additional error in OCSP processing that was preventing OCSP soft fail working with Tomcat's APR/native connector. (markt)

• Correct logic error that prevented the configuration of TLS 1.3 cipher suites. (markt)

• Refactor the addition of TLS 1.3 cipher suite configuration to avoid a regression when running a version of Tomcat that pre-dates this change. (markt)

• Rename configure.in to modern autotools style configure.ac. (rjung)
• Fix incomplete updates for autotools generated files during "buildconf" execution. (rjung)
• Improve quoting in tcnative.m4. (rjung)
• Update the minimum version of autoconf for releasing to 2.68. (rjung)
• Fix the autoconf warnings when creating a release. (markt)
• The Windows binaries are now built with OCSP support enabled by default. (markt)
• Include a nonce with OCSP requests and check the nonce, if any, in the OCSP response. (markt)
• Expand verification of OCSP responses. (markt)
• Add the ability to configure the OCSP checks to soft-fail - i.e. if the responder cannot be contacted or fails to respond in a timely manner the OCSP check will not fail. (markt)
• Add a configurable timeout to the writing of OCSP requests and reading of OCSP responses. (markt)
• Add the ability to control the OCSP verification flags. (markt)
• Configure TLS 1.3 connections from the provided ciphers list as well as connections using TLS 1.2 and earlier. Pull request provided by gastush. (markt)
• Update the Windows build environment to use Visual Studio 2022. (markt)

• Fix a crash on Windows when SSLContext.setCACertificate() is invoked with a null value for caCertificateFile and a non-null value for caCertificatePath until properly addressed with https://github.com/openssl/openssl/issues/24416. (michaelo)
• Use ERR_error_string_n with a definite buffer length as a named constant. (schultz)
• Ensure local reference capacity is available when creating new arrays and Strings. (schultz)
• Update the recommended minimum version of OpenSSL to 3.0.14. (markt)

• Drop useless compile.optimize option. (michaelo)
• Align Java source compile configuration with Tomcat. (michaelo)
• Fix version set in DLL header on Windows. (michaelo)
• Remove an unreachable if condition around CRLs in sslcontext.c. (michaelo)
• 67818: When calling SSL.setVerify() or SSLContext.setVerify(), the default verify paths are no longer set. Only the explicitly configured trust store, if any, will be used. (michaelo)
• Update the minimum supported version of LibreSSL to 3.5.2. (markt)
• Remove NPN support as NPN was never standardised and browser support was removed in 2019. (markt)
• Update the recommended minimum version of OpenSSL to 3.0.13. (markt)
