The shared libraries are now stored as members of archives, as it is usual on AIX. To correctly address this the custom dladdr()-implementation as well as the dlfcn_load() routine need to be able to cope with such a construct: libname.a(libname.so). Signed-off-by:

We recently turned on the TLSv1.3 downgrade sentinels by default. Unfortunately we are using a very old version of the BoringSSL test runner which uses an old draft implementation of TLSv1.3 that also uses the downgrade sentinels by default. The two implementations do not play well together and were causing spurious test failures. Until such time as we update the BoringSSL test runner we disable the failing tests: SendFallbackSCSV In this test the client is OpenSSL and the server is the boring test runner. The client and server fail to negotiate TLSv1.3 because the test runner is using an old draft TLSv1.3 version. The server does however add the TLSv1.3->TLSv1.2 downgrade sentinel in the ServerHello random. Since we recently turned on checking of the downgrade sentinels on the client side this causes the connection to fail. VersionNegotiationExtension-TLS11 In this test the test runner is the client and OpenSSL is the server. The test modifies the supported_versio...

We need to ensure that the min-max version range we use when constructing the ClientHello is the same range we use when we validate the version selected by the ServerHello. Otherwise this may appear as a fallback or downgrade. Fixes #6964 Reviewed-by:

Fixes #7022 In pull request #6432 a change was made to keep the handles to the random devices opened in order to avoid reseeding problems for applications in chroot environments. As a consequence, the handles of the random devices were leaked at exit if the random generator was not used by the application. This happened, because the call to RAND_set_rand_method(NULL) in rand_cleanup_int() triggered a call to the call_once function do_rand_init, which opened the random devices via rand_pool_init(). Thanks to GitHub user @bwelling for reporting this issue. Reviewed-by:

This commit destroys the free list pointers which would otherwise be present in the returned memory blocks. This in turn helps prevent information leakage from the secure memory area. Note: CRYPTO_secure_malloc is not guaranteed to return zeroed memory: before the secure memory system is initialised or if it isn't implemented. Reviewed-by:

The EFD database does not state that the "ladd-2002-it-3" algorithm assumes X1 != 0. Consequently the current implementation, based on it, fails to compute correctly if the affine x coordinate of the scalar multiplication input point is 0. We replace this implementation using the alternative algorithm based on Eq. (9) and (10) from the same paper, which being derived from the additive relation of (6) does not incur in this problem, but costs one extra field multiplication. The EFD entry for this algorithm is at https://hyperelliptic.org/EFD/g1p/auto-shortw-xz.html#ladder-ladd-2002-it-4 and the code to implement it was generated with tooling. Regression tests add one positive test for each named curve that has such a point. The `SharedSecret` was generated independently from the OpenSSL codebase with sage. This bug was originally reported by Dmitry Belyavsky on the openssl-users maling list: https://mta.openssl.org/pipermail/openssl-users/2018-August/008540.html Co-authored-by:

CRYPTO_atomic_read was added with intention to read statistics counters, but readings are effectively indistinguishable from regular load (even in non-lock-free case). This is because you can get out-dated value in both cases. CRYPTO_atomic_write was added for symmetry and was never used. Reviewed-by:
