Prior to this commit we were keeping a count of how many KeyUpdates we

is not sufficient for long running connections. Since many KeyUpdates
would not be a particular good DoS route anyway, the simplest solution is
to simply remove the key update count.

(cherry picked from commit 3409a5ff8a)
This commit adds a simple unit test to make sure that the constant-time
flag does not "leak" among BN_CTX frames:
- test_ctx_consttime_flag() initializes (and later frees before
returning) a BN_CTX object, then it calls in sequence
test_ctx_set_ct_flag() and test_ctx_check_ct_flag() using the same
BN_CTX object. The process is run twice, once with a "normal"
BN_CTX_new() object, then with a BN_CTX_secure_new() one.
- test_ctx_set_ct_flag() starts a frame in the given BN_CTX and sets the
BN_FLG_CONSTTIME flag on some of the BIGNUMs obtained from the frame
before ending it.
- test_ctx_check_ct_flag() then starts a new frame and gets a number of
BIGNUMs from it. In absence of leaks, none of the BIGNUMs in the new
frame should have BN_FLG_CONSTTIME set.
In actual BN_CTX usage inside libcrypto the leak could happen at any
depth level in the BN_CTX stack, with varying results depending on the
patterns of sibling trees of nested function calls sharing the same
BN_CTX object, and the effect of unintended BN_FLG_CONSTTIME on the
called BN_* functions.
This simple unit test abstracts away this complexity and verifies that
the leak does not happen between two sibling functions sharing the same
BN_CTX object at the same level of nesting.

The original 1.1.1 design was to use SSL_CB_HANDSHAKE_START and
SSL_CB_HANDSHAKE_DONE to signal start/end of a post-handshake message
exchange in TLSv1.3. Unfortunately experience has shown that this confuses
some applications who mistake it for a TLSv1.2 renegotiation. This means
that KeyUpdate messages are not handled properly.
This commit removes the use of SSL_CB_HANDSHAKE_START and
SSL_CB_HANDSHAKE_DONE to signal the start/end of a post-handshake
message exchange. Individual post-handshake messages are still signalled in
the normal way.
This is a potentially breaking change if there are any applications already
written that expect to see these TLSv1.3 events. However, without it,
KeyUpdate is not currently usable for many applications.

During a DTLS handshake we may need to periodically handle timeouts in the
DTLS timer to ensure retransmits due to lost packets are performed. However,
one peer will always complete a handshake before the other. The DTLS timer
stops once the handshake has finished so any handshake messages lost after
that point will not automatically get retransmitted simply by calling
DTLSv1_handle_timeout(). However attempting an SSL_read implies a
DTLSv1_handle_timeout() and additionally will process records received from
the peer. If those records are themselves retransmits then we know that the
peer has not completed its handshake yet and a retransmit of our final
flight automatically occurs.

pkey_test_ctrl() was designed for parsing values, not for using in

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.

Commit 5b4cb385c1 (#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.

still be used for our internal purposes, such as internal tests.
When building non-shared, the renaming mechanism doesn't come into

In pull request #4328 the seeding of the DRBG via RAND_add()/RAND_seed()
was implemented by buffering the data in a random pool where it is
picked up later by the rand_drbg_get_entropy() callback. This buffer
was limited to the size of 4096 bytes.
When a larger input was added via RAND_add() or RAND_seed() to the DRBG,
the reseeding failed, but the error returned by the DRBG was ignored
by the two calling functions, which both don't return an error code.
As a consequence, the data provided by the application was effectively
ignored.
This commit fixes the problem by a more efficient implementation which
does not copy the data in memory and by raising the buffer the size limit
to INT32_MAX (2 gigabytes). This is less than the NIST limit of 2^35 bits
but it was chosen intentionally to avoid platform dependent problems
like integer sizes and/or signed/unsigned conversion.
Additionally, the DRBG is now less permissive on errors: In addition to
pushing a message to the openssl error stack, it enters the error state,
which forces a reinstantiation on next call.
Thanks go to Dr. Falko Strenzke for reporting this issue to the
openssl-security mailing list. After internal discussion the issue
has been categorized as not being security relevant, because the DRBG
reseeds automatically and is fully functional even without additional
randomness provided by the application.
