- Separate ngtcp2_transport_params.
ngtcp2/ngtcp2@05d7adc made ngtcp2_transport_params separate from
ngtcp2_settings.
ngtcp2 master is required to build curl with http3 support.
Closes#6554
As the info is already stored in the transfer handle anyway, there's no
need to carry around a duplicate buffer for the life-time of the handle.
Closes#6534
... in most cases instead of 'struct connectdata *' but in some cases in
addition to.
- We mostly operate on transfers and not connections.
- We need the transfer handle to log, store data and more. Everything in
libcurl is driven by a transfer (the CURL * in the public API).
- This work clarifies and separates the transfers from the connections
better.
- We should avoid "conn->data". Since individual connections can be used
by many transfers when multiplexing, making sure that conn->data
points to the current and correct transfer at all times is difficult
and has been notoriously error-prone over the years. The goal is to
ultimately remove the conn->data pointer for this reason.
Closes#6425
This field needs to be wide enough to hold sockaddr_in6 when
connecting via IPv6. Otherwise, ngtcp2_conn_read_pkt will drop the
packets because of the address mismatch:
I00000022 [...] con ignore packet from unknown path
We can safely assume that struct sockaddr_storage is available, as it
is used in the public interface of ngtcp2.

* fix two build errors due to mismatch between function
declarations and their definitions
* silence two mismatched signs warnings via casts

Closes#6093
For QUIC but also for regular TCP when the second family runs out of IPs
with a failure while the first family is still trying to connect.
Separated the timeout handling for IPv4 and IPv6 connections when they
both have a number of addresses to iterate over.
quiche now requires the application to explicitly set the keylog path
for each connection, rather than reading the environment variable
itself.
Closes#5541
When the method is updated inside libcurl we must still not change the
method as set by the user as then repeated transfers with that same
handle might not execute the same operation anymore!
This fixes the libcurl part of #5462
Test 1633 added to verify.
Closes#5499
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.
If the QLOGDIR environment variable is set, enable qlogging.
... and create Curl_qlogdir() in the new generic vquic/vquic.c file for
QUIC functions that are backend independent.
Closes#5353
quiche has the potential to log qlog files. To enable this, you must
build quiche with the qlog feature enabled `cargo build --features
qlog`. curl then passes a file descriptor to quiche, which takes
ownership of the file. The FD transfer only works on UNIX.
The convention is to enable logging when the QLOGDIR environment is
set. This should be a path to a folder where files are written with the
naming template <SCID>.qlog.
