Commit 9ef9088c switched the SSL/SSL_CTX statistics counters to using Thread-Sanitizer-friendly primitives. However, it erroneously converted an addition of -1 (for s->session_ctx->stats.sess_accept) to an addition of +1, since that is the only counter API provided by the internal tsan_assist.h header until the previous commit. This means that for each accepted (initial) connection, the session_ctx's counter would get doubly incremented, and the (switched) ctx's counter would also get incremented. Restore the counter decrement so that each accepted connection increments exactly one counter exactly once (in net effect). Reviewed-by:

The existing tsan_counter() API increments a reference counter. Provide a new API, tsan_decr(), to decrement such a reference counter. This can be used, for example, when a reference is added to the session_ctx's sess_accept stats but should more properly be tracked in the regular ctx's statistics. Reviewed-by:

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 5b4cb385c18a (#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 8bf366519661 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 8bf366519661 (e.g., renamings of private variables, fixes of typographical errors, comment changes) manually back to 1.1.1. The commits a83dc59afa2e (#7399) and 8817215d5c52 (#7456) failed to cherry-pick previously to 1.1.1, with this patch they both cherry-pick without conflicts. Reviewed-by:
