* connections: introduce http/3 happy eyeballsStefan Eissing2023-02-021-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 - fix upload pytests and improve parallel transfer performance. 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 - checking httpd version 2.4.55 for test_05 cases where it is needed. Skipping with message if too old. - catch exception when checking for caddy existance on system. Closes #10349

* Makefile.mk: portable Makefile.m32Viktor Szakats2022-11-223-73/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Update bare GNU Make `Makefile.m32` to: - Move objects into a subdirectory. - Add support for MS-DOS. Tested with DJGPP. - Add support for Watt-32 (on MS-DOS). - Add support for AmigaOS. - Rename `Makefile.m32` to `Makefile.mk` - Replace `ARCH` with `TRIPLET`. - Build `tool_hugehelp.c` proper (when tools are available). - Drop MS-DOS compatibility macro `USE_ZLIB` (replaced by `HAVE_LIBZ`) - Add support for `ZLIB_LIBS` to override `-lz`. - Omit object files when building examples. - Default `CC` to `gcc` once again, for convenience. (Caveat: compiler name `cc` cannot be set now.) - Set `-DCURL_NO_OLDIES` for examples, like autotools does. - Delete `makefile.dj` files. Notice the configuration details and defaults are not retained with the new method. - Delete `makefile.amiga` files. A successful build needs a few custom options. We're also not retaining all build details from the existing Amiga make files. - Rename `Makefile.m32` to `Makefile.mk` to reflect that they are not Windows/MinGW32-specific anymore. - Add support for new `CFG` options: `-map`, `-debug`, `-trackmem` - Set `-DNDEBUG` by default. - Allow using `-DOS=...` in all `lib/config-*.h` headers, syncing this with `config-win32.h`. - Look for zlib parts in `ZLIB_PATH/include` and `ZLIB_PATH/lib` instead of bare `ZLIB_PATH`. Note that existing build configurations for MS-DOS and AmigaOS likely become incompatible with this change. Example AmigaOS configuration: ``` export CROSSPREFIX=/opt/amiga/bin/m68k-amigaos- export CC=gcc export CPPFLAGS='-DHAVE_PROTO_BSDSOCKET_H' export CFLAGS='-mcrt=clib2' export LDFLAGS="${CFLAGS}" export LIBS='-lnet -lm' make -C lib -f Makefile.mk make -C src -f Makefile.mk ``` Example MS-DOS configuration: ``` export CROSSPREFIX=/opt/djgpp/bin/i586-pc-msdosdjgpp- export WATT_PATH=/opt/djgpp/net/watt export ZLIB_PATH=/opt/djgpp export OPENSSL_PATH=/opt/djgpp export OPENSSL_LIBS='-lssl -lcrypt' export CFG=-zlib-ssl make -C lib -f Makefile.mk make -C src -f Makefile.mk ``` Closes #9764
* lib: feature deprecation warnings in gcc >= 4.3Patrick Monnerat2022-11-151-1/+2
| | | | | | | | | | | | | | | | | | | | | | | Add a deprecated attribute to functions and enum values that should not be used anymore. This uses a gcc 4.3 dialect, thus is only available for this version of gcc and newer. Note that the _Pragma() keyword is introduced by C99, but is available as part of the gcc dialect even when compiling in C89 mode. It is still possible to disable deprecation at a calling module compile time by defining CURL_DISABLE_DEPRECATION. Gcc type checking macros are made aware of possible deprecations. Some testing support Perl programs are adapted to the extended declaration syntax. Several test and unit test C programs intentionally use deprecated functions/options and are annotated to not generate a warning. New test 1222 checks the deprecation status in doc and header files. Closes #9667

* Makefile.m32: deduplicate build rules [ci skip]Viktor Szakats2022-10-041-145/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After this patch, we reduce the three copies of most `Makefile.m32` logic to one. This now resides in `lib/Makefile.m32`. It makes future updates easier, the code shorter, with a small amount of added complexity. `Makefile.m32` reduction: | | bytes | LOC total | blank | comment | code | |-------------------|-------:|----------:|-------:|---------:|------:| | 7.85.0 | 34772 | 1337 | 79 | 192 | 1066 | | before this patch | 17601 | 625 | 62 | 106 | 457 | | after this patch | 11680 | 392 | 52 | 104 | 236 | Details: - Change rules to create objects for the `v*` subdirs in the `lib` dir. This allows to use a shared compile rule and assumes that filenames are not (and will not be) colliding across these directories. `Makefile.m32` now also stores a list of these subdirs. They are changing rarely though. - Sync as much as possible between the three `Makefile.m32` scripts' rules and their source/target sections. - After this patch `CPPFLAGS` are all applied to the `src` sources once again. This matches the behaviour of cmake/autotools. Only zlib ones are actually required there. - Use `.rc` names from `Makefile.inc` instead of keeping a duplicate. - Change examples to link `libcurl.dll` by default. This makes building trivial, even as a cross-build: `CC=x86_64-w64-mingw32-gcc make -f Makefile.m32` To run them, you need to move/copy or add-to-path `libcurl.dll`. You can select static mode via `CFG=-static`. - List more of the `Makefile.m32` config variables. - Drop `.rc` support from examples. It made it fragile without much benefit. - Include a necessary system lib for the `externalsocket.c` example. - Exclude unnecessary systems libs when building in `-dyn` mode. Closes #9642
* Makefile.m32: major rework [ci skip]Viktor Szakats2022-10-031-276/+109
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch overhauls `Makefile.m32` scripts, fixing a list of quirks, making its behaviour and customization envvars align better with other build systems, aiming for less code, that is easier to read, use and maintain. Details: - Rename customization envvars: `CURL_CC` -> `CC` `CURL_RC` -> `RC` `CURL_AR` -> `AR` `CURL_LDFLAG_EXTRAS_DLL` -> `CURL_LDFLAGS_LIB` `CURL_LDFLAG_EXTRAS_EXE` -> `CURL_LDFLAGS_BIN` - Drop `CURL_STRIP` and `CURL_RANLIB`. These tools are no longer used. - Accept `CFLAGS`, `CPPFLAGS`, `RCFLAGS`, `LDFLAGS` and `LIBS` envvars. - Drop `CURL_CFLAG_EXTRAS`, `CURL_LDFLAG_EXTRAS`, `CURL_RCFLAG_EXTRAS` in favor of the above. - Do not automatically enable `zlib` with `libssh2`. `zlib` is optional with `libssh2`. - Omit unnecessary `CPPFLAGS` options when building `curl.exe` and examples. - Drop support for deprecated `-winssl` `CFG` option. Use `-schannel` instead. - Avoid late evaluation where not necessary (`=` -> `:=`). - Drop support for `CURL_DLL_A_SUFFIX` to override the implib suffix. Instead, use the standard naming scheme by default: `libcurl.dll.a`. The toolchain recognizes the name, and selects it automatically when asking for a `-shared` vs. `-static` build. - Stop applying `strip` to `libcurl.a`. Follow-up from 16a58e9f93c7e89e1f87720199388bcfcfa148a4. There was no debug info to strip since then. - Stop setting `-O3`, `-W`, `-Wall` options. You can add these to `CFLAGS` as desired. - Always enable `-DCURL_DISABLE_OPENSSL_AUTO_LOAD_CONFIG` with OpenSSL, to avoid that vulnerability on Windows. - Add `-lbrotlicommon` to `LIBS` when using `brotli`. - Do not enable `-nghttp3` without `-ngtcp2`. - `-ssh2` and `-rtmp` options no longer try to auto-select a TLS-backend. You need to set the backend explicitly. This scales better and avoids issues with certain combinations (e.g. `libssh2` + `wolfssl` with no `schannel`). - Default to OpenSSL TLS-backend with `ngtcp2`. Possible to override via `NGTCP2_LIBS`. - Old, alternate method of enabling components (e.g. `SSH2=1`) no longer supported. - Delete `SPNEGO` references. They were no-ops. - Drop support for Win9x environments. - Allow setting `OPENSSL_LIBS` independently from `OPENSSL_LIBPATH`. - Support autotools/CMake `libssh2` builds by default. - Respect `CURL_DLL_SUFFIX` in `-dyn` mode when building `curl.exe` and examples. - Assume standard directory layout with `LIBCARES_PATH`. (Instead of the long gone embedded one.) - Stop static linking with c-ares by default. Add `CPPFLAGS=-DCARES_STATICLIB` to enable it. - Reorganize internal layout to avoid redundancy and emit clean diffs between src/lib and example make files. - Delete unused variables. - Code cleanups/rework. - Comment and indentation fixes. Closes #9632
* Makefile.m32: delete legacy component bits [ci skip]Viktor Szakats2022-10-021-36/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Drop auto-detection of OpenSSL 1.0.2 and earlier. Now always defaulting to OpenSSL 1.1.0 and later, LibreSSL and BoringSSL. - Drop `Invalid path to OpenSSL package` detection. OpenSSL has been using a standard file layout since 1.1.0, so this seems unnecessary now. - Drop special logic to enable Novell LDAP SDK support. - Drop special logic to enable OpenLDAP LDAP SDK support. This seems to be distinct from native OpenLDAP, with support implemented inside `lib/ldap.c` (vs. `lib/openldap.c`) back when the latter did not exist yet in curl. - Add `-lwldap32` only if there is no other LDAP library (either native OpenLDAP, or SDKs above) present. - Update `doc/INSTALL.md` accordingly. After this patch, it's necessary to make configration changes when using OpenSSL 1.0.2 or earlier, or the two LDAP SDKs. OpenSSL 1.0.2 and earlier: ``` export OPENSSL_INCLUDE = <path-to-openssl>/outinc export OPENSSL_LIBPATH = <path-to-openssl>/out export OPENSSL_LIBS = -lssl32 -leay32 -lgdi32 ``` Novell LDAP SDK, previously enabled via `USE_LDAP_NOVELL=1`: ``` export CURL_CFLAG_EXTRAS = -I<path-to-sdk>/inc -DCURL_HAS_NOVELL_LDAPSDK export CURL_LDFLAG_EXTRAS = -L<path-to-sdk>/lib/mscvc -lldapsdk -lldapssl -lldapx ``` OpenLDAP LDAP SDK, previously enabled via `USE_LDAP_OPENLDAP=1`: ``` export CURL_CFLAG_EXTRAS = -I<path-to-sdk>/include -DCURL_HAS_OPENLDAP_LDAPSDK export CURL_LDFLAG_EXTRAS = -L<path-to-sdk>/lib -lldap -llber ``` I haven't tested these scenarios, and in general we recommend using a recent OpenSSL release. Also, WinLDAP (the Windows default) and OpenLDAP (via `-DUSE_OPENLDAP`) are the LDAP options actively worked on in curl. Closes #9631
* Makefile.m32: cleanups and fixes [ci skip]Viktor Szakats2022-10-011-85/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Add `-lcrypt32` once, and add it always for simplicity. - Delete broken link and reference to the pre-Vista WinIDN add-on. MS no longer distribute it. - Delete related `WINIDN_PATH` option. IDN is a system lib since Vista. - Sync `LIBCARES_PATH` default with the rest of dependencies. - Delete version numbers from dependency path defaults. - `libgsasl` package is now called `gsasl`. - Delete `libexpat` and `libxml2` references. No longer used by curl. - Delete `Edit the path below...` comments. We recommend to predefine those envvars instead. - `libcares.a` is not an internal dependency anymore. Stop using it as such. - `windres` `--include-dir` -> `-I`, `-F` -> `--target=` for readability. - Delete `STRIP`, `CURL_STRIP`, `AR` references from `src/Makefile.m32`. They were never used. - Stop to `clean` some objects twice in `src/Makefile.m32`. - Delete cvs-specific leftovers. - Finish resource support in examples make file. - Delete `-I<root>/lib` from examples make file. - Fix copyright start year in examples make file. - Delete duplicate `ftpuploadresume` input in examples make file. - Sync OpenSSL lib order, `SYNC` support, `PROOT` use, dependency path defaults, variables names and other internal bits between the three make files. - `lib/Makefile.m32` accepted custom options via `DLL_LIBS` envvar. This was lib-specific and possibly accidental. Use `CURL_LDFLAG_EXTRAS_DLL` envvar for the same effect. - Fix linking `curl.exe` and examples to wrong static libs with auto-detected OpenSSL 1.0.2 or earlier. - Add `-lgdi32` for OpenSSL 1.0.2 and earlier only. - Add link to Novell LDAP SDK and use a relative default path. Latest version is from 2016, linked to an outdated OpenSSL 1.0.1. - Whitespace and comment cleanups. TODO in a next commit: Delete built-in detection/logic for OpenSSL 1.0.2 and earlier, the Novell LDAP SDK and the other LDAP SDK (which is _not_ OpenLDAP). Write up the necessary custom envvars to configure them. Closes #9616

* Makefile.m32: allow -nghttp3/-ngtcp2 without -ssl [ci skip]Viktor Szakats2022-08-151-12/+14
| | | | | | | | | | | | | | | | | | | | | | Before this patch `-nghttp3`/`-ngtcp2` had an effect only when `-ssl` was also enabled. `-ssl` meaning OpenSSL (and its forks). After 8a13be227eede2601c2b3b1c63e08b3dc9b35dd5 nghttp3/ngtcp2 can also be used together with wolfSSL. This patch adds the ability to enable `-nghttp3`/`-ngtcp2` independently from `-ssl` (OpenSSL), allowing to use it with wolfSSL or other, future TLS backends. Before this patch, it was fine to enable `-nghttp3`/`-ngtcp2` unconditionally. After this patch, this is no longer the case, and now it's the user's responsibility to enable `-nghttp3`/`-ngtcp2` only together with a compatible TLS backend. When using a TLS backend other than OpenSSL, the TLS-specific ngtcp2 library must be configured manually, e.g.: `export CURL_LDFLAG_EXTRAS=-lngtcp2_crypto_wolfssl` (or via `NGTCP2_LIBS`) Closes #9314
* Makefile.m32: add `CURL_RC` and `CURL_STRIP` variables [ci skip]Viktor Szakats2022-07-101-1/+4
| | | | | | | | | | | | | | They allow to override the hardcoded values for the `windres` and `strip` tools, complementing the existing set of `CURL_{CC,AR,RANLIB}` variables. `CURL_RC` comes handy when using LLVM tools with `CROSSPREFIX=llvm-` and `CURL_CC=clang` set on current latest debian:unstable or earlier, where `llvm-windres` is missing, and a `CURL_RC=<triplet>-windres` fixes it. Hopefully this will be fixed in the llvm package. FWIW `llvm-windres` does exist in Homebrew llvm, MSYS2 llvm and llvm-mingw. Reviewed-by: Daniel Stenberg Closes #9132

* CURLOPT_SERVER_RESPONSE_TIMEOUT: the new nameDaniel Stenberg2022-07-051-1/+1
| | | | | | | | | | | Starting now, CURLOPT_FTP_RESPONSE_TIMEOUT is the alias instead of the other way around.

Closes #9104
* makefile.m32: add support for custom ARCH [ci skip]Viktor Szakats2022-07-041-1/+3
| | | | | | | | | | | | | | When building curl for target platform other than x64 and x86, it is now possible to pass `ARCH=custom`, that will omit all hardcoded logic for setting up CFLAGS/LDFLAGS/RCFLAGS for these platforms, and let these be customized via `CURL_CFLAG_EXTRAS`, `CURL_LDFLAG_EXTRAS`, and a newly added one for the resource compiler: `CURL_RCFLAG_EXTRAS`. This makes it possible to use `makefile.m32` to build for ARM64 for example. Reviewed-by: Daniel Stenberg Closes #9092
* windows: improve random sourceViktor Szakats2022-07-041-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Use the Windows API to seed the fallback random generator. This ensures to always have a random seed, even when libcurl is built with a vtls backend lacking a random generator API, such as rustls (experimental), GSKit and certain mbedTLS builds, or, when libcurl is built without a TLS backend. We reuse the Windows-specific random function from the Schannel backend. - Implement support for `BCryptGenRandom()` [1] on Windows, as a replacement for the deprecated `CryptGenRandom()` [2] function. It is used as the secure random generator for Schannel, and also to provide entropy for libcurl's fallback random generator. The new function is supported on Vista and newer via its `bcrypt.dll`. It is used automatically when building for supported versions. It also works in UWP apps (the old function did not). - Clear entropy buffer before calling the Windows random generator. This avoids using arbitrary application memory as entropy (with `CryptGenRandom()`) and makes sure to return in a predictable state when an API call fails.

* Makefile.m32: stop forcing XP target with ipv6 enabled [ci skip]Viktor Szakats2022-06-221-1/+1
| | | | | | | | | | | | | | | | | | | Since this [1] commit in 2011, `_WIN32_WINNT` was set fixed to Windows XP when the `-ipv6` option is selected. Maybe this was added to support pre-XP Windows versions (?). These days libcurl builds fine for both XP and post-XP versions with IPv6 support enabled. The relevance of pre-XP version is also low by now. Other build methods also do not impose such limitation for a similar configuration. So, drop this hard-wired `_WIN32_WINNT` limit from `Makefile.m32`, thus building for the default Windows version set by the compiler. This is Vista for recent MinGW versions. Old behaviour can be restored by setting this envvar: export CURL_CFLAG_EXTRAS=-D_WIN32_WINNT=0x0501 [1] 98a61d8e2e8982786aaf3916cbbcac96838316e7 Closes #9035
* reuse/dep5: adjusted to parse betterDaniel Stenberg2022-06-141-0/+6
| | | | | | ... adjusted a few files to contain copyright and license info. Closes #9006
* copyright: make repository REUSE compliantmax.mehl2022-06-13121-112/+368
| | | | | | | | | | | Add licensing and copyright information for all files in this repository. This either happens in the file itself as a comment header or in the file `.reuse/dep5`. This commit also adds a Github workflow to check pull requests and adapts copyright.pl to the changes. Closes #8869
* examples/crawler.c: use the curl licenseDaniel Stenberg2022-06-021-3/+14
| | | | | | | With permission from Jeroen Ooms URL: https://github.com/curl/curl/pull/8869#issuecomment-1144742731 Closes #8950
* examples: remove fopen.c and rtsp.cDaniel Stenberg2022-06-023-839/+0
| | | | | | | | | | | To simplify the license situation, as they were the only files in the source tree using these specific BSD-3 clause licenses. For an fopen style API, we recommend instead going https://github.com/curl/fcurl Ref: #8869 Closes #8949
* Makefile.m32: delete obsolete options, improve -On [ci skip]Viktor Szakats2022-05-241-6/+4
| | | | | | | | | | | | | | | | - `-D_AMD64_` has not been necessary for mingw-w64 builds for a long time now. - `-fno-strict-aliasing` is mentioned for Intel C compiler in autotools, and I used this with VxWorks in another project, but otherwise this isn't necessary anymore as a default. If a target still needs it, it can be added with `CURL_CFLAG_EXTRAS=-fno-strict-aliasing` - bump up default optimization level to `-O3` (from `-O2`), and also rearrange option order so the default can now be overridden via `CURL_CFLAG_EXTRAS`. - delete `-g` (generate debug info) from `CFLAGS` and `-s` from `LDFLAGS` (strip debug info). They were working against each other. Now, if someone needs debug info, it can be enabled via `CURL_CFLAG_EXTRAS=-g` Closes #8904
