From a6a29f19e15b67de430724f45ae96bbcf6b202e1 Mon Sep 17 00:00:00 2001 From: Stefan Eissing Date: Tue, 31 Jan 2023 13:08:04 +0100 Subject: [PATCH] New cfilter HTTP-CONNECT for h3/h2/http1.1 eyeballing. - filter is installed when `--http3` in the tool is used (or the equivalent CURLOPT_ done in the library) - starts a QUIC/HTTP/3 connect right away. Should that not succeed after 100ms (subject to change), a parallel attempt is started for HTTP/2 and HTTP/1.1 via TCP - both attempts are subject to IPv6/IPv4 eyeballing, same as happens for other connections - tie timeout to the ip-version HAPPY_EYEBALLS_TIMEOUT - use a `soft` timeout at half the value. When the soft timeout expires, the HTTPS-CONNECT filter checks if the QUIC filter has received any data from the server. If not, it will start the HTTP/2 attempt. HTTP/3(ngtcp2) improvements. - setting call_data in all cfilter calls similar to http/2 and vtls filters for use in callback where no stream data is available. - returning CURLE_PARTIAL_FILE for prematurely terminated transfers - enabling pytest test_05 for h3 - shifting functionality to "connect" UDP sockets from ngtcp2 implementation into the udp socket cfilter. Because unconnected UDP sockets are weird. For example they error when adding to a pollset. HTTP/3(quiche) improvements. - fixed upload bug in quiche implementation, now passes 251 and pytest - error codes on stream RESET - improved debug logs - handling of DRAIN during connect - limiting pending event queue HTTP/2 cfilter improvements. - use LOG_CF macros for dynamic logging in debug build - fix CURLcode on RST streams to be CURLE_PARTIAL_FILE - enable pytest test_05 for h2 GOAWAY handling for ngtcp2/quiche - during connect, when the remote server refuses to accept new connections and closes immediately (so the local conn goes into DRAIN phase), the connection is torn down and a another attempt is made after a short grace period. This is the behaviour observed with nghttpx when we tell it to shut down gracefully. Tested in pytest test_03_02. TLS improvements - ALPN selection for SSL/SSL-PROXY filters in one vtls set of functions, replaces copy of logic in all tls backends. - standardized the infof logging of offered ALPNs - ALPN negotiated: have common function for all backends that sets alpn proprty and connection related things based on the negotiated protocol (or lack thereof). - new tests/tests-httpd/scorecard.py for testing h3/h2 protocol implementation. Invoke: python3 tests/tests-httpd/scorecard.py --help for usage. Improvements on gathering connect statistics and socket access. - new CF_CTRL_CONN_REPORT_STATS cfilter control for having cfilters report connection statistics. This is triggered when the connection has completely connected. - new void Curl_pgrsTimeWas(..) method to report a timer update with a timestamp of when it happend. This allows for updating timers "later", e.g. a connect statistic after full connectivity has been reached. - in case of HTTP eyeballing, the previous changes will update statistics only from the filter chain that "won" the eyeballing. - new cfilter query CF_QUERY_SOCKET for retrieving the socket used by a filter chain. Added methods Curl_conn_cf_get_socket() and Curl_conn_get_socket() for convenient use of this query. - Change VTLS backend to query their sub-filters for the socket when checks during the handshake are made. HTTP/3 documentation on how https eyeballing works. TLS improvements - ALPN selection for SSL/SSL-PROXY filters in one vtls set of functions, replaces copy of logic in all tls backends. - standardized the infof logging of offered ALPNs - ALPN negotiated: have common function for all backends that sets alpn proprty and connection related things based on the negotiated protocol (or lack thereof). Scorecard with Caddy. - configure can be run with `--with-test-caddy=path` to specify which caddy to use for testing - tests/tests-httpd/scorecard.py now measures download speeds with caddy pytest improvements - adding Makfile to clean gen dir - adding nghttpx rundir creation on start --- .github/scripts/spellcheck.words | 3 + configure.ac | 19 + docs/HTTP3.md | 28 +- docs/examples/http3.c | 3 +- lib/Makefile.inc | 6 +- lib/cf-http.c | 518 ++++++++++++++++++++ lib/cf-http.h | 58 +++ lib/cf-socket.c | 230 +++++++-- lib/cf-socket.h | 20 +- lib/cfilters.c | 31 +- lib/cfilters.h | 33 +- lib/connect.c | 162 +++++-- lib/connect.h | 26 +- lib/curl_log.c | 4 + lib/http.c | 93 ++-- lib/http.h | 8 +- lib/http2.c | 624 +++++++++++++++---------- lib/http2.h | 14 +- lib/http_proxy.c | 24 +- lib/progress.c | 36 +- lib/progress.h | 7 + lib/socks.c | 2 +- lib/urldata.h | 1 + lib/vquic/curl_msh3.c | 23 +- lib/vquic/curl_ngtcp2.c | 354 +++++++++----- lib/vquic/curl_quiche.c | 296 +++++++----- lib/vquic/vquic.c | 48 +- lib/vquic/vquic.h | 8 +- lib/vtls/bearssl.c | 63 +-- lib/vtls/gskit.c | 12 +- lib/vtls/gtls.c | 65 +-- lib/vtls/mbedtls.c | 49 +- lib/vtls/nss.c | 64 +-- lib/vtls/openssl.c | 66 +-- lib/vtls/rustls.c | 67 +-- lib/vtls/schannel.c | 69 +-- lib/vtls/sectransp.c | 44 +- lib/vtls/vtls.c | 188 +++++++- lib/vtls/vtls.h | 44 +- lib/vtls/vtls_int.h | 2 + lib/vtls/wolfssl.c | 54 +-- tests/Makefile.am | 2 +- tests/libtest/lib2502.c | 2 +- tests/tests-httpd/Makefile.am | 27 ++ tests/tests-httpd/config.ini.in | 8 +- tests/tests-httpd/conftest.py | 2 +- tests/tests-httpd/scorecard.py | 400 ++++++++++++++++ tests/tests-httpd/test_01_basic.py | 5 + tests/tests-httpd/test_02_download.py | 74 +-- tests/tests-httpd/test_03_goaway.py | 16 +- tests/tests-httpd/test_04_stuttered.py | 29 +- tests/tests-httpd/test_05_errors.py | 17 +- tests/tests-httpd/test_06_eyeballs.py | 86 ++++ tests/tests-httpd/test_07_upload.py | 150 ++++++ tests/tests-httpd/testenv/__init__.py | 1 + tests/tests-httpd/testenv/caddy.py | 164 +++++++ tests/tests-httpd/testenv/curl.py | 91 +++- tests/tests-httpd/testenv/env.py | 77 ++- tests/tests-httpd/testenv/httpd.py | 7 +- tests/tests-httpd/testenv/nghttpx.py | 93 +++- 60 files changed, 3511 insertions(+), 1206 deletions(-) create mode 100644 lib/cf-http.c create mode 100644 lib/cf-http.h create mode 100644 tests/tests-httpd/Makefile.am create mode 100644 tests/tests-httpd/scorecard.py create mode 100644 tests/tests-httpd/test_06_eyeballs.py create mode 100644 tests/tests-httpd/test_07_upload.py create mode 100644 tests/tests-httpd/testenv/caddy.py diff --git a/.github/scripts/spellcheck.words b/.github/scripts/spellcheck.words index 6486dacb94665d..1a7223e0f23cc6 100644 --- a/.github/scripts/spellcheck.words +++ b/.github/scripts/spellcheck.words @@ -335,6 +335,9 @@ IoT ipadOS IPCXN IPv +IPv4 +IPv4/6 +IPv6 IRIs IRIX Itanium diff --git a/configure.ac b/configure.ac index 1a4e21c260f192..a58e266cf68aec 100644 --- a/configure.ac +++ b/configure.ac @@ -311,6 +311,16 @@ AS_HELP_STRING([--with-test-nghttpx=PATH],[where to find nghttpx for testing]), ) AC_SUBST(TEST_NGHTTPX) +CADDY=caddy +AC_ARG_WITH(test-caddy,dnl +AS_HELP_STRING([--with-test-caddy=PATH],[where to find caddy for testing]), + CADDY=$withval + if test X"$OPT_CADDY" = "Xno" ; then + CADDY="" + fi +) +AC_SUBST(CADDY) + dnl we'd like a httpd+apachectl as test server dnl AC_ARG_WITH(test-httpd, [AS_HELP_STRING([--with-test-httpd=PATH], @@ -366,6 +376,14 @@ fi AC_PATH_PROG([APXS], [apxs]) AC_SUBST(HTTPD_NGHTTPX) +dnl the Caddy server we might use in testing +if test "x$TEST_CADDY" != "x"; then + CADDY="$TEST_CADDY" +else + AC_PATH_PROG([CADDY], [caddy]) +fi +AC_SUBST(CADDY) + dnl If no TLS choice has been made, check if it was explicitly disabled or dnl error out to force the user to decide. if test -z "$TLSCHOICE"; then @@ -4646,6 +4664,7 @@ AC_CONFIG_FILES([Makefile \ tests/libtest/Makefile \ tests/unit/Makefile \ tests/tests-httpd/config.ini \ + tests/tests-httpd/Makefile \ packages/Makefile \ packages/vms/Makefile \ curl-config \ diff --git a/docs/HTTP3.md b/docs/HTTP3.md index 8e83490dda302a..bab3831f02ebad 100644 --- a/docs/HTTP3.md +++ b/docs/HTTP3.md @@ -239,7 +239,11 @@ directory, or copy `msquic.dll` and `msh3.dll` from that directory to the # `--http3` -Use HTTP/3 directly: +Use only HTTP/3: + + curl --http3-only https://nghttp2.org:4433/ + +Use HTTP/3 with fallback to HTTP/2 or HTTP/1.1 (see "HTTPS eyeballing" below): curl --http3 https://nghttp2.org:4433/ @@ -249,6 +253,28 @@ Upgrade via Alt-Svc: See this [list of public HTTP/3 servers](https://bagder.github.io/HTTP3-test/) +### HTTPS eyeballing + +With option `--http3` curl will attempt earlier HTTP versions as well should the connect +attempt via HTTP/3 not succeed "fast enough".
