Prevent unexpected array entry conversion when reading key
When passing an array, the key entry can get converted to a string if it
is an object, but this actually modifies the original array entry.
The test originally outputted:
```
array(2) {
[0]=>
string(...) => ...
[1]=>
string(0) ""
}
```
This is unexpected. Use zval_try_get_string() to prevent this behaviour.
Closes GH-16693.
The `offset_sec` parameter of `X509_gmtime_adj()` expects a `long`, but
the `$days` parameter of `openssl_csr_sign()` a `zend_long`. We must
avoid signed integer overflow (UB), but also must not silently truncate.
Thus we check the given `$days` for the permissible range, and bail out
otherwise.
Closes GH-16437.
We must not use `try_convert_to_string()` on members of unseparated
array arguments; instead of separating, we use `zval_try_get_string()`.
Closes GH-16370.
For openssl_pkey_get_details we export the priv+pub parameters.
ED25519/ED448 do not support streaming, so we need to use
EVP_Digest{Sign,Verify} instead. In general the older EVP_{Sign,Verify}
interface should be avoided as the key is passed very late.
See BUGS section in OpenSSL manpages of EVP_{Sign,Verify}Final
Additionally per requirement we need to allow sign/verify without
digest. So we need to allow passing 0 as digest. In OpenSSL 3.0+ this also
corresponds to the default digest (see EVP_PKEY_get_default_digest_name).
For CSR creation we need to allow "null" as digest_alg option.
Closes GH-14052
Port 64325 is already used in ext/standard/tests/streams/gh11418.phpt. The test
randomly times out, and it's unclear whether it might be related to the
conflicting port.
php_socket_errno() may return a stale value when recv returns a
value >= 0. As such, the liveness check is wrong.
This is the same bug as #70198 (fixed in GH-1456). So we fix it in the
same way.
Closes GH-13895.
This fixes the issue with unbounded waiting on SSL_peek which can happen
when only part of the record is fetched. It makes socket non blocking so
it is possible to verify if OpenSSL is expecting some more data or if
there is an error.
This also fixes bug #79501
Closes GH-13487
Bumps the minimum required OpenSSL version from 1.0.2 to 1.1.1.
OpenSSL 1.1.1 is an LTS release, but has reached[^1] EOL from upstream. However, Linux distro/OS vendors
continue to ship OpenSSL 1.1.1, so 1.1.1 was picked as the minimum. The current minimum 1.0.2 reached
EOL in 2018.
Bumping the minimum required OpenSSL version makes it possible for ext-openssl to remove a bunch of
conditional code, and assume that TLS 1.3 (shipped with OpenSSL 1.1.1) will be supported everywhere.
- Debian buster: 1.1.1[^2]
- Ubuntu 20.04: 1.1.1[^3]
- CentOS/RHEL 7: 1.0.2
- RHEL 8/Rocky 8/EL 8: 1.1.1
- Fedora 38: 3.0.9 (`openssl11` provides OpenSSL 1.1 as well)
RHEL/CentOS 7 reaches EOL mid 2024, so for PHP 8.4 scheduled towards the end of this year, we can safely
bump the minimum OpenSSL version.
