This function works in exactly the same way as openssl_cipher_iv_length
but for a key length. This is especially useful to make sure that the
right key length is provided to openssl_encrypt and openssl_decrypt.
In addtion the change also updates implementation of
openssl_cipher_iv_length and adds a test for it.
This adds support for ChaCha20-Poly1305 AEAD algorithm so it is possible
to use it in the same way as AES GCM and other AEAD algorithms. This is
available in OpenSSL 1.1.0+.
This has only been done for Windows systems so far, and there was a
TODO comment about looping for larger values; that appears to be
overkill, though, since 2 million bytes should be sufficient for all
use cases, and if there is really the need for more, users can still
loop manually. Anyhow, checking the range upfront on all platforms
is clearer then silently casting to `int`.
We split the error message for the least possible BC break.
Closes GH-9126.
Fix targeted for oses defining those flags as enums (like Linux/glibc).
`error: converting the enum constant to a boolean [-Werror,-Wint-in-bool-context]
} else if ((!sslsock->ssl_active && value == 0 && (MSG_DONTWAIT || !sslsock->s.is_blocked)) ||`
Closes#8895.
If there is a zero timeout and MSG_DONTWAIT is available (or the
socket is non-blocking), the poll() call is not necessary, and we can
just call recv() right away.
Before this change:
poll([{fd=4, events=POLLIN|POLLPRI|POLLERR|POLLHUP}], 1, 0) = 0 (Timeout)
poll([{fd=4, events=POLLIN|POLLERR|POLLHUP}], 1, 60000) = 1 ([{fd=4, revents=POLLIN}])
recvfrom(4, "HTTP/1.1 301 Moved Permanently\r\n"..., 8192, MSG_DONTWAIT, NULL, NULL) = 348
poll([{fd=4, events=POLLIN|POLLPRI|POLLERR|POLLHUP}], 1, 0) = 1 ([{fd=4, revents=POLLIN}])
recvfrom(4, "", 1, MSG_PEEK, NULL, NULL) = 0
After this change:
recvfrom(4, 0x7ffe0cc719a0, 1, MSG_PEEK|MSG_DONTWAIT, NULL, NULL) = -1 EAGAIN (Resource temporarily unavailable)
poll([{fd=4, events=POLLIN|POLLERR|POLLHUP}], 1, 60000) = 1 ([{fd=4, revents=POLLIN}])
recvfrom(4, "HTTP/1.1 301 Moved Permanently\r\n"..., 8192, MSG_DONTWAIT, NULL, NULL) = 348
recvfrom(4, "", 1, MSG_PEEK|MSG_DONTWAIT, NULL, NULL) = 0
The first poll() is replaced by recvfrom(), and the third poll() is
omitted completely.
ext/openssl/xp_ssl: eliminate poll() when MSG_DONTWAIT is available
If there is a zero timeout and MSG_DONTWAIT is available (or the
socket is non-blocking), the poll() call is not necessary, and we can
just call recv() right away.
Closes GH-8092.
It introduces a single function to check file paths passed to OpenSSL
functions. It expands the path, check null bytes and finally does
an open basedir check.
The unexpected EOF failure was introduced in OpenSSL 3.0 to prevent
truncation attack. However there are many non complaint servers and
it is causing break for many users including potential majority
of those where the truncation attack is not applicable. For that reason
we try to keep behavior consitent with older OpenSSL versions which is
also the path chosen by some other languages and web servers.
Closes GH-8369
This test fails because san-cert.pem and san-ca.pem have expired. We
fix that by using the CertificateGenerator to generate temporary certs
during the test run. Since san-cert.pem and san-ca.pem have been
identical, we only generate one certificate.
Closes GH-7763.
Allow $tag to be null. This is the value that openssl_encrypt()
sets it to for non-AEAD ciphers, so we should also accept this
as an input to openssl_decrypt().
Prior to PHP 8.1, null was accepted in weak mode due to the special
treatment of null arguments to internal functions.
