There is code that retries calling RAND_bytes() until it gets something

4984448648 In UI_OpenSSL's open(), generate an error on unknown errno
TTY_get() sometimes surprises us with new errno values to determine if
we have a controling terminal or not.  This generated error is a
helpful tool to figure out that this was what happened and what the
unknown value is.

Since there are many parts of UI_process() that can go wrong, it isn't
very helpful to only return -1 with no further explanation.  With this

b7a7f39afe Stop init loops
Under certain circumstances, the libcrypto init code would loop,
causing a deadlock.  This would typically happen if something in
ossl_init_base() caused an OpenSSL error, and the error stack routines
would recurse into the init code before the flag that ossl_init_base()
had been run was checked.

This change makes sure ossl_init_base isn't run once more of the base
is initiated.

Thanks to Dmitry Kostjuchenko for the idea.

1fda5bc435 Revert "Fixed deadlock in CRYPTO_THREAD_run_once for Windows"
This reverts commit 349d1cfddc.

The proposed fix is incorrect. It marks the "run_once" code as having
finished before it has. The intended semantics of run_once is that no
threads should proceed until the code has run exactly once. With this
change the "second" thread will think the run_once code has already been
run and will continue, even though it is still in progress. This could
result in a crash or other incorrect behaviour.

operands are passed down to assembler. Module in question uses pshufb

608a026494 Implement RSASSA-PKCS1-v1_5 as specified.
RFC 3447, section 8.2.2, steps 3 and 4 states that verifiers must encode
the DigestInfo struct and then compare the result against the public key
operation result. This implies that one and only one encoding is legal.

OpenSSL instead parses with crypto/asn1, then checks that the encoding
round-trips, and allows some variations for the parameter. Sufficient
laxness in this area can allow signature forgeries, as described in
https://www.imperialviolet.org/2014/09/26/pkcs1.html

Although there aren't known attacks against OpenSSL's current scheme,
this change makes OpenSSL implement the algorithm as specified. This
avoids the uncertainty and, more importantly, helps grow a healthy
ecosystem. Laxness beyond the spec, particularly in implementations
which enjoy wide use, risks harm to the ecosystem for all. A signature
producer which only tests against OpenSSL may not notice bugs and
accidentally become widely deployed. Thus implementations have a
responsibility to honor the specification as tightly as is practical.

In some cases, the damage is permanent and the spec deviation and
security risk becomes a tax all implementors must forever pay, but not
here. Both BoringSSL and Go successfully implemented and deployed
RSASSA-PKCS1-v1_5 as specified since their respective beginnings, so
this change should be compatible enough to pin down in future OpenSSL
releases.

See also https://tools.ietf.org/html/draft-thomson-postel-was-wrong-00

As a bonus, by not having to deal with sign/verify differences, this
version is also somewhat clearer. It also more consistently enforces
digest lengths in the verify_recover codepath. The NID_md5_sha1 codepath
wasn't quite doing this right.

5836780f43 Ensure that libcrypto and libssl do not unload until the process exits
Because we use atexit() to cleanup after ourselves, this will cause a
problem if we have been dynamically loaded and then unloaded again: the
atexit() handler may no longer be there.

Most modern atexit() implementations can handle this, however there are
still difficulties if libssl gets unloaded before libcrypto, because of
the atexit() callback that libcrypto makes to libssl.

The most robust solution seems to be to ensure that libcrypto and libssl
never unload. This is done by simply deliberately leaking a dlopen()
reference to them.

a1f2b0e6e0 Do not set load_crypto_strings_inited when OPENSSL_NO_ERR is defined
Only set the load_crypto_strings_inited to 1 when err_load_crypto_strings_int was called.

This solves the following issue:
- openssl is built with no-err
- load_crypto_strings_inited is set to 1 during the OPENSSL_init_crypto call
- During the cleanup: OPENSSL_cleanup, err_free_strings_int is called because load_crypto_strings_inited == 1
- err_free_strings_int calls do_err_strings_init because it has never been called
- Now do_err_strings_init calls OPENSSL_init_crypto
- But since we are in the cleanup (stopped == 1) this results in an error:
  CRYPTOerr(CRYPTO_F_OPENSSL_INIT_CRYPTO, ERR_R_INIT_FAIL);
- which then tries to initialize everything we are trying to clean up: ERR_get_state, ossl_init_thread_start, etc

Some hardware devices don't provide the public EC_POINT data. The only
way for X509_check_private_key() to validate that the key matches a
given certificate is to actually perform a sign operation and then
verify it using the public key in the certificate.

Maybe that can come later, as discussed in issue 1532. But for now let's
at least make it fail gracefully and not crash.

216e8d9103 Improve the definition of STITCHED_CALL in e_rc4_hmac_md5.c
The definition of STITCHED_CALL relies on OPENSSL_NO_ASM.  However,
when a configuration simply lacks the assembler implementation for RC4
(which is where we have implemented the stitched call), OPENSSL_NO_ASM
isn't implemented.  Better, then, to rely on specific macros that
indicated that RC4 (and MD5) are implemented in assembler.

For this to work properly, we must also make sure Configure adds the
definition of RC4_ASM among the C flags.

SCT_verify_v1 is redundant, since SCT_validate does the same verification
(by calling SCT_verify) and more. The API is less confusing with a single
verification function (SCT_validate).

3ba1ef829c bn/asm/x86[_64]-mont*.pl: implement slightly alternative page-walking.
Original strategy for page-walking was adjust stack pointer and then
touch pages in order. This kind of asks for double-fault, because
if touch fails, then signal will be delivered to frame above adjusted
stack pointer. But touching pages prior adjusting stack pointer would
upset valgrind. As compromise let's adjust stack pointer in pages,
touching top of the stack. This still asks for double-fault, but at
least prevents corruption of neighbour stack if allocation is to
overstep the guard page.

Also omit predict-non-taken hints as they reportedly trigger illegal
instructions in some VM setups.
