Now that all functions in select.[ch] take timediff_t instead
of the limited int or long, we can remove type conversions

Avoiding conversions from time_t was already done in 842f73de.

On some systems, openssl 1.0.x is still the default, but it has been
patched to contain all the recent security fixes. As a result of this
patching, it is possible for macro X509_V_FLAG_NO_ALT_CHAINS to be
defined, while the previous behavior of openssl to not look at trusted
chains first, remains.
Fix it: ensure X509_V_FLAG_TRUSTED_FIRST is always set, do not try to
probe for the behavior of openssl based on the existence ofmacros.
Closes#5530
Commit 4a4b63d forgot to set the expected SOCKS5 reply length when the
reply ATYP is X'01'. This resulted in erroneously expecting more bytes

remotely resolving the hostname).

When the method is updated inside libcurl we must still not change the

Tested with ngtcp2 built against the OpenSSL library. Additionally
tested with MultiSSL (NSS for TLS and ngtcp2+OpenSSL for QUIC).
The TLS backend (independent of QUIC) may or may not already have opened
the keylog file before. Therefore Curl_tls_keylog_open is always called
to ensure the file is open.
Tested following the same curl and tshark commands as in commit
"vtls: Extract and simplify key log file handling from OpenSSL" using
WolfSSL v4.4.0-stable-128-g5179503e8 from git master built with
`./configure --enable-all --enable-debug CFLAGS=-DHAVE_SECRET_CALLBACK`.
Full support for this feature requires certain wolfSSL build options,
see "Availability note" in lib/vtls/wolfssl.c for details.
Closes#5327
Create a set of routines for TLS key log file handling to enable reuse
with other TLS backends. Simplify the OpenSSL backend as follows:
- Drop the ENABLE_SSLKEYLOGFILE macro as it is unconditionally enabled.
- Do not perform dynamic memory allocation when preparing a log entry.
Unless the TLS specifications change we can suffice with a reasonable
fixed-size buffer.
- Simplify state tracking when SSL_CTX_set_keylog_callback is
unavailable. My original sslkeylog.c code included this tracking in
order to handle multiple calls to SSL_connect and detect new keys
after renegotiation (via SSL_read/SSL_write). For curl however we can
be sure that a single master secret eventually becomes available
after SSL_connect, so a simple flag is sufficient. An alternative to
the flag is examining SSL_state(), but this seems more complex and is
not pursued. Capturing keys after server renegotiation was already
unsupported in curl and remains unsupported.
Tested with curl built against OpenSSL 0.9.8zh, 1.0.2u, and 1.1.1f
(`SSLKEYLOGFILE=keys.txt curl -vkso /dev/null https://localhost:4433`)
against an OpenSSL 1.1.1f server configured with:
# Force non-TLSv1.3, use TLSv1.0 since 0.9.8 fails with 1.1 or 1.2
openssl s_server -www -tls1
# Likewise, but fail the server handshake.
openssl s_server -www -tls1 -Verify 2
# TLS 1.3 test. No need to test the failing server handshake.
openssl s_server -www -tls1_3
Verify that all secrets (1 for TLS 1.0, 4 for TLS 1.3) are correctly
written using Wireshark. For the first and third case, expect four
matches per connection (decrypted Server Finished, Client Finished, HTTP
Request, HTTP Response). For the second case where the handshake fails,
expect a decrypted Server Finished only.
tshark -i lo -pf tcp -otls.keylog_file:keys.txt -Tfields \
-eframe.number -eframe.time -etcp.stream -e_ws.col.Info \
-dtls.port==4433,http -ohttp.desegment_body:FALSE \
-Y 'tls.handshake.verify_data or http'
A single connection can easily be identified via the `tcp.stream` field.
For HTTP 1.x, it's a protocol error when the server sends more bytes
than announced. If this happens, don't reuse the connection, because the
start position of the next response is undefined.
