LibYAML has moved from their previous Mercurial based hosting on BitBucket to a git repository on GitHub. This commit updates the `Psych` module's documentation to point to this new repository, instead of the old one which is now a 404.

I'm not sure whether this handles all multithreaded use cases,
but this handles the example that crashes almost immediately
and does 10,000,000 total deflates using 100 separate threads.
To prevent the tests from taking forever, the committed test
for this uses only 10,000 deflates across 10 separate threads,
which still causes a segfault in the previous implementation
almost immediately.
Fixes [Bug #17803]

* It used to be hardcoded since 0affbf9d2c7c5c618b8d3fe191e74d9ae8ad22fc
but got removed in 23abf3d3fb82afcc26d35769f0dec59dd46de4bb
* This means that since that second commit, rb_iterate() was used unintentionally.

Back in 2016, we chose not to use Bundler in Ruby/OpenSSL development
because Bundler depended on openssl and could not be used for testing
openssl itself - "bundle exec rake test" would end up with loading two
different versions of openssl at the same time.
This has been resolved long time ago. We can now safely use it for
development dependency management and for Rake tasks.

Also, OpenSSL::BN::CONSTTIME is added.
OpenSSL itself had a feature that was vulnerable against a side-channel
attack. The OpenSSL authors determined that it was not a security issue,
and they have already fixed the issue by using BN_set_flags.
https://github.com/openssl/openssl/pull/13888
If a Ruby OpenSSL user was faced with a similar issue, they couldn't
prevent the issue because Ruby OpenSSL lacks a wrapper to BN_set_flags.
For the case, this change introduces the wrapper.

With the newly added OpenSSL::PKey::PKey#{sign,verify}_raw,
OpenSSL::PKey::DSA's low level signing operation methods can be
implemented in Ruby. The definitions are now in lib/openssl/pkey.rb.

With the newly added OpenSSL::PKey::PKey#{sign,verify}_raw,
OpenSSL::PKey::EC's low level signing operation methods can be
implemented in Ruby. The definitions are now in lib/openssl/pkey.rb.
1f9da0cd9d
Implement these methods using the new OpenSSL::PKey::PKey#{encrypt,sign}
family. The definitions are now in lib/openssl/pkey.rb.
Also, recommend using those generic methods in the documentation.

Add a variant of PKey#sign and #verify that do not hash the data
automatically.
Sometimes the caller has the hashed data only, but not the plaintext
to be signed. In that case, users would have to use the low-level API
such as RSA#private_encrypt or #public_decrypt directly.
OpenSSL 1.0.0 and later supports EVP_PKEY_sign() and EVP_PKEY_verify()
which provide the same functionality as part of the EVP API. This patch
adds wrappers for them.

Remove the following methods, which have been marked as deprecated and
produced a warning since version 2.0, commit 7ea72f1f5084 ("adapt
OpenSSL::PKey to OpenSSL 1.1.0 opaque structs", 2016-06-05).
- OpenSSL::PKey::RSA#n=, #e=, #d=, #p=, #q=, #dmp1=, #dmq1=, #iqmp=
- OpenSSL::PKey::DSA#p=, #q=, #g=, #priv_key=, #pub_key=
- OpenSSL::PKey::DH#p=, #g=, #priv_key=, #pub_key=
These methods could only work with OpenSSL 1.0.2 or older, which is now
EOL.

Methods that take both PEM-encoding and DER-encoding have not been
consistent in the order in which encoding to attempt to parse.
A DER-encoding may contain a valid PEM block ("\n-----BEGIN ..-----" to
"-----END ...-----") embedded within it. Also, the PEM-encoding parser
allows arbitrary data around the PEM block and silently skips it. As a
result, attempting to parse data in DER-encoding as PEM-encoding first
can incorrectly finds the embedded PEM block instead.
This commit ensures that DER encoding will always be attempted before
PEM encoding. OpenSSL::X509::Certificate is one of the updated classes.
With this, the following will always be true:
# obj is an OpenSSL::X509::Certificate
obj == OpenSSL::X509::Certificate.new(obj.to_der)
obj == OpenSSL::X509::Certificate.new(obj.to_pem)

Normal sockets respond to `getbyte`, so we should make SSLSocket respond
to `getbyte` as well. This way we can substitute SSLSockets for regular
sockets.

Use EVP_PKEY_param_check() instead of DH_check() if available. Also,
use EVP_PKEY_public_check() instead of EC_KEY_check_key().
EVP_PKEY_*check() is part of the EVP API and is meant to replace those
low-level functions. They were added by OpenSSL 1.1.1. It is currently
not provided by LibreSSL.

The low-level API that is used to implement #public_key is deprecated
in OpenSSL 3.0. It is actually very simple to implement in another way,
using existing methods only, in much shorter code. Let's do it.
While we are at it, the documentation is updated to recommend against
using #public_key. Now that OpenSSL::PKey::PKey implements public_to_der
method, there is no real use case for #public_key in newly written Ruby
programs.
48a6c391ef
Use EVP_PKEY_print_private() instead of the low-level API *_print()
functions, such as RSA_print().
EVP_PKEY_print_*() family was added in OpenSSL 1.0.0.
Note that it falls back to EVP_PKEY_print_public() and
EVP_PKEY_print_params() as necessary. This is required for EVP_PKEY_DH
type for which _private() fails if the private component is not set in
the pkey object.
Since the new API works in the same way for all key types, we now
implement #to_text in the base class OpenSSL::PKey::PKey rather than in
each subclass.

The previous series of commits re-implemented key generation with the
low level API with the EVP API. The BN_GENCB-based callback function is
no longer used.
81027b7463
Implement PKey::DSA.new(size) and PKey::DSA.generate using
OpenSSL::PKey.generate_parameters and .generate_key instead of the low
level DSA functions.
1800a8d5eb
Implement PKey::DH.new(size, gen), PKey::DH.generate(size, gen), and
PKey::DH#generate_key! using PKey.generate_parameters and .generate_key
instead of the low level DH functions.
Note that the EVP interface can enforce additional restrictions - for
example, DH key shorter than 2048 bits is no longer accepted by default
in OpenSSL 3.0. The test code is updated accordingly.

rb_thread_call_without_gvl() can be interrupted, but it may be able to
resume the operation. Call rb_thread_check_ints() to see if it raises
an exception or not.
88b90fb856
Similarly to OpenSSL::PKey.generate_key and .generate_parameters, let
OpenSSL::PKey::PKey#sign and #verify take an optional parameter for
specifying control strings for EVP_PKEY_CTX_ctrl_str().
faf85d7c1d
The routine to apply Hash to EVP_PKEY_CTX_ctrl_str() is currently used
by key generation, but it is useful for other operations too. Let's
change it to a slightly more generic name.

Fix potential leak of EVP_MD_CTX object in an error path. This path is
normally unreachable, since the size of a signature generated by any
supported algorithms would not be larger than LONG_MAX.

Similarly to OpenSSL >= 1.1.0, LibreSSL 2.9.0 ensures thread safety
without requiring applications to set locking callbacks and made
related functions no-op.

LibreSSL 2.2.2 introduced TLS_method(), but with different semantics
from OpenSSL: TLS_method() enabled TLS >= 1.0 while SSLv23_method()
enabled all available versions, which included SSL 3.0 in addition.
However, LibreSSL 2.3.0 removed SSL 3.0 support completely and now
TLS_method() and SSLv23_method() are equivalent.
3b7d7045b8
SSL_CTX_set_ecdh_auto() exists in OpenSSL 1.1.0 and LibreSSL 2.6.1, but
it is made no-op and the automatic curve selection cannot be disabled.
Wrap it with ifdef to make it clear that it is safe to remove it
completely when we drop support for OpenSSL 1.0.2.
2ae8f21234
Clean up old version guards in preparation for the upcoming OpenSSL 3.0
support.
OpenSSL 1.0.1 reached its EOL on 2016-12-31. At that time, we decided
to keep 1.0.1 support because many major Linux distributions were still
shipped with 1.0.1. Now, nearly 4 years later, most Linux distributions
are reaching their EOL and it should be safe to assume nobody uses them
anymore. Major ones that were using 1.0.1:
- Ubuntu 14.04 is EOL since 2019-04-30
- RHEL 6 will reach EOL on 2020-11-30
LibreSSL 3.0 and older versions are no longer supported by the LibreSSL
team as of October 2020.
Note that OpenSSL 1.0.2 also reached EOL on 2019-12-31 and 1.1.0 also
did on 2018-08-31.
