In TLSv1.2 and below a CertificateRequest is sent after the Certificate from the server. This means that by the time the client_cert_cb is called on receipt of the CertificateRequest a call to SSL_get_peer_certificate() will return the server certificate as expected. In TLSv1.3 a CertificateRequest is sent before a Certificate message so calling SSL_get_peer_certificate() returns NULL. To workaround this we delay calling the client_cert_cb until after we have processed the CertificateVerify message, when we are doing TLSv1.3. Fixes #7384 Reviewed-by:

pkey_test_ctrl() was designed for parsing values, not for using in test runs. Relying on its returned value when it returned 1 even for control errors made it particularly useless for mac_test_run(). Here, it gets replaced with a MAC specific control function, that parses values the same way but is designed for use in a _run() rather than a _parse() function. This uncovers a SipHash test with an invalid control that wasn't caught properly. After all, that stanza is supposed to test that invalid control values do generate an error. Now we catch that.

We made the build of foo.obj depend on foo.d, meaning the latter gets built first. Unfortunately, the way the compiler works, we are forced to redirect all output to foo.d, meaning that if the source contains an error, the build fails without showing those errors. We therefore remove the dependency and force the build of foo.d to always happen after build of foo.obj. Reviewed-by:

Commit 5b4cb385 (#7382) introduced a bug which had the effect that RAND_add()/RAND_seed() failed for buffer sizes less than 32 bytes. The reason was that now the added random data was used exlusively as entropy source for reseeding. When the random input was too short or contained not enough entropy, the DRBG failed without querying the available entropy sources. This commit makes drbg_add() act smarter: it checks the entropy requirements explicitely. If the random input fails this check, it won't be added as entropy input, but only as additional data. More precisely, the behaviour depends on whether an os entropy source was configured (which is the default on most os): - If an os entropy source is avaible then we declare the buffer content as additional data by setting randomness to zero and trigger a regular reseeding. - If no os entropy source is available, a reseeding will fail inevitably. So drbg_add() uses a trick to mix the buffer contents into the DRBG state without forcing a reseeding: it generates a dummy random byte, using the buffer content as additional data.

In commit 8bf36651 some renamings andd typo fixes were made while adding back the DRBG-HMAC and DRBG-HASH implementation. Since the commit could not be backported, a lot of unnecessary differences between master and 1.1.1 were introduced. These differences result in tiresome merge conflicts when cherry-picking. To minimize these merge-conflicts, this patch ports all 'non-feature' changes of commit 8bf36651 (e.g., renamings of private variables, fixes of typographical errors, comment changes) manually back to 1.1.1. The commits a83dc59a (#7399) and 8817215d (#7456) failed to cherry-pick previously to 1.1.1, with this patch they both cherry-pick without conflicts. Reviewed-by:

In commit 820e414d (pr #5247) the summary output of the Configure command was optimized towards instructing people how to create issue reports.

This commit makes the summary output start with a success to prevent a misunderstanding. Also it gives more hints to new OpenSSL users. Reviewed-by:

When building shared libraries on Windows, we had a clash between 'libcrypto.lib' the static routine library and 'libcrypto.lib' the import library. We now change it so the static versions of our libraries get '_static' appended to their names. These will never get installed, but can still be used for our internal purposes, such as internal tests. When building non-shared, the renaming mechanism doesn't come into play. In that case, the static libraries 'libcrypto.lib' and 'libssl.lib' are installed, just as always. Fixes #7492 Reviewed-by:

This bug was introduced by #7382 which enhanced RAND_add() to accept large buffer sizes. As a consequence, RAND_add() now fails for buffer sizes less than 32 bytes (i.e. less than 256 bits). In addition, rand_drbg_get_entropy() forgets to reset the attached drbg->pool in the case of an error, which leads to the heap corruption. The problem occurred with RAND_load_file(), which reads the file in chunks of 1024 bytes each. If the size of the final chunk is less than 32 bytes, then RAND_add() fails, whence RAND_load_file() fails silently for buffer sizes n = k * 1024 + r with r = 1,...,31. This commit fixes the heap corruption only. The other issues will be addressed in a separate pull request. Thanks to Gisle Vanem for reporting this issue. Fixes #7449 Reviewed-by:

We only had targets for the "simple" shared library names (libfoo.so and not libfoo.so.x.y on Unix, import library libfoo.lib but not libfoo.dll on Windows). This has created some confusion why it wasn't possible to rebuild the less "simple" name directly (just as an example, someone who mistook the import library on Windows for a static library, removed the DLL and then found it was difficult to rebuild directly), so we change the target to include all possible names.

Previously when a ClientHello arrives with a valid cookie using DTLSv1_listen() we only "peeked" at the message and left it on the underlying fd. This works fine for single threaded applications but for multi-threaded apps this does not work since the fd is typically reused for the server thread, while a new fd is created and connected for the client. By "peeking" we leave the message on the server fd, and consequently we think we've received another valid ClientHello and so we create yet another fd for the client, and so on until we run out of fds. In this new approach we remove the ClientHello and buffer it in the SSL object. Fixes #6934 Reviewed-by:
