Co-authored-by: Jay Satiro Closes #13169 Matt Jolly (25 Mar 2024) - curl-rustls.m4: add pkg-config support to rustls detection Based on the existing openssl pkg-config detection, this commit tries to use pkg-config to find `rustls` then falls back to the current approach if that fails. We use the following logic: - if no path is provided, just use pkg-config, if it's not there we have a problem! - if a path is provided, try pkg-config + if pkg-config fails, try and find rustls directly Closes #13179 Mohammadreza Hendiani (25 Mar 2024) - TODO: update 13.11 with more information Closes #13173 Daniel Stenberg (23 Mar 2024) - docs/libcurl: generate PROTOCOLS from meta-data Remove the PROTOCOLS section from the source files completely and instead generate them based on the header data in the curldown files. It also generates TLS backend information for options marked for TLS as protocol. Closes #13175 - CURLMOPT_MAX*: mention what happens if changed mid-transfer For CURLMOPT_MAXCONNECTS and CURLMOPT_MAX_HOST_CONNECTIONS Ref: #13158 Closes #13176 - docs/libcurl: add TLS backend info for all TLS options All man pages that are listed to be for TLS now must also specify exactly what TLS backends the option works for, or use All if they all work. cd2nroff makes sure this is done and that the listed backends exist. Closes #13168 - docs/libcurl: cleanups - CURLINFO_TLS_SESSION.md: remove mention of NSS - CURLINFO_TLS_SSL_PTR.md: remove NSS leftover - CURLOPT_CAINFO.md: drop mention of backends not supporting this - CURLOPT_CAPATH.md: wolfSSL also supports this Closes #13166 - docs: make each libcurl man specify protocol(s) The mandatory header now has a mandatory list of protocols for which the manpage is relevant. Most man pages already has a "PROTOCOLS" section, but this introduces a stricter way to specify the relevant protocols. cd2nroff verifies that at least one protocol is mentioned (which can be `*`). This information is not used just yet, but A) the PROTOCOLS section can now instead get generated and get a unified wording across all manpages and B) this allows us to more reliably filter/search for protocol specific manpages/options. Closes #13166 Stefan Eissing (21 Mar 2024) - http2, http3: only return CURLE_PARTIAL_FILE when bytes were received - should resolve spurious pytest failures when stream were reset right after response header were received Clsoes #13151 - http: separate response parsing from response action - move code that triggers on end-of-response into separate function from parsing - simplify some headp/headerlen usage - add `httpversion` to SingleRequest to indicate the version of the current response Closes #13134 Daniel Stenberg (21 Mar 2024) - http2: remove the third (unused) argument from http2_data_done() Closes #13154 - RELEASE-NOTES: synced Evgeny Grin (Karlson2k) (21 Mar 2024) - RELEASE-NOTES: corrected Corrected link for item 118 Closes #13157 Daniel Stenberg (19 Mar 2024) - CURLOPT_INTERFACE.md: remove spurious amp, add see-also Closes #13149 Stefan Eissing (19 Mar 2024) - http: improve response header handling, save cpu cycles Saving some cpu cycles in http response header processing: - pass the length of the header line along - use string constant sizeof() instead of strlen() - check line length if prefix is possible - switch on first header char to limit checks Closes #13143 Daniel Stenberg (19 Mar 2024) - tool_getparam: accept a blank -w "" Added test 468 to verify. Regression from 07bcae89d5d00 (shipped in 8.6.0) Reported-by: Thomas Pyle Fixes #13144 Closes #13145 Evgeny Grin (Karlson2k) (18 Mar 2024) - curl_sha512_256: work around a NetBSD bug Based on Michael Kaufmann analysis and suggestion Closes #13133 Stefan Eissing (18 Mar 2024) - http: expect 100 rework Move all handling of HTTP's `Expect: 100-continue` feature into a client reader. Add sending flag `KEEP_SEND_TIMED` that triggers transfer sending on general events like a timer. HTTP installs a `CURL_CR_PROTOCOL` reader when announcing `Expect: 100-continue`. That reader works as follows: - on first invocation, records time, starts the `EXPIRE_100_TIMEOUT` timer, disables `KEEP_SEND`, enables `KEEP_SEND_TIMER` and returns 0, eos=FALSE like a paused upload. - on subsequent invocation it checks if the timer has expired. If so, it enables `KEEP_SEND` and switches to passing through reads to the underlying readers. Transfer handling's `readwrite()` will be invoked when a timer expires (like `EXPIRE_100_TIMEOUT`) or when data from the server arrives. Seeing `KEEP_SEND_TIMER`, it will try to upload more data, which triggers reading from the client readers again. Which then may lead to a new pausing or cause the upload to start. Flags and timestamps connected to this have been moved from `SingleRequest` into the reader's context.

Added test 1481 to verify. Both the server and the proxy versions. Reported-by: Boris Verkhovskiy Fixes #13127 Closes #13129 - GHA/linux: add sysctl trick to work-around GitHub runner issue The GitHub image runner update from 20240304.1.0 to 20240310.1 introduces a problem for clang-14. The issue is caused by incompatibility between llvm 14 provided in ubuntu-22.04 image and the much newer kernel configured with high-entropy ASLR. As a work-around, we issue a sysctl command to lower the entropy and get clang-14 to work again.

"Set this" instead "tell curl to set" or "this sets..." Plus some extra cleanups and rephrasing. Closes #13106 - managen: remove space before protocols For options that are listed for specific protocols, the protocols (shown first within parentheses) are now output without the leading space in the manpage output. Closes #13105 Jay Satiro (12 Mar 2024) - mbedtls: properly cleanup the thread-shared entropy - Store the state of the thread-shared entropy for global init/cleanup. - Use curl's thread support of mbedtls for all Windows builds instead of just when the threaded resolver is used via USE_THREADS_WIN32. Prior to this change on global cleanup curl builds that have curl thread support for mbedtls freed the entropy (8b1d2298) but failed to mark that it had been freed, which caused problems on subsequent init + transfer. Bug: https://github.com/curl/curl/discussions/11919#discussioncomment-8687105 Reported-by: awesomekosm@users.noreply.github.com Closes https://github.com/curl/curl/pull/13071 Daniel Stenberg (12 Mar 2024) - tool_getparam: handle non-existing (out of range) short-options ... correctly, even when they follow an existing one without a space in between. Verify with test 467 Follow-up to 07dd60c05b Reported-by: Geeknik Labs Fixes #13101 Closes #13102 Stefan Eissing (11 Mar 2024) - lib: move 'done' parameter to SingleRequests A transfer may do several `SingleRequest`s for its success. This happens regularly for authentication, follows and retries on failed connections. The "readwrite()" calls and functions connected to those carried a `bool *done` parameter to indicate that the current `SingleRequest` is over. This may happen before `upload_done` or `download_done` bits of `SingleRequest` are set. The problem with that is now `write_resp()` protocol handlers are invoked in places where the `bool *done` cannot be passed up to the caller. Instead of being a bool in the call chain, it needs to become a member of `SingleRequest`, reflecting its state. This removes the `bool *done` parameter and adds the `done` bit to `SingleRequest` instead. It adds `Curl_req_soft_reset()` for using a `SingleRequest` in a follow up, clearing `done` and other flags/counters.

Closes https://github.com/curl/curl/pull/13085 Daniel Stenberg (8 Mar 2024) - docs/cmdline-opts: drop the curl.1 from the dist tarball Since it is no longer needed for building tool_hugehelp.c and all the docs is available in readable markdown format in the tarball, the peeps that don't want to build the manpage still do good. Removing it also fixes the complexity of out-of-tree builds when the curl.1 exists in the source tree. - test1140/1173: extend wildcards to find curl.1 ... in its new build path. Also update the test scripts to be more precise in error messages to help us understand CI errors better.

Closes #13070 - digest: add check for hashing error Closes #13072 Viktor Szakats (7 Mar 2024) - cmake: enable `ENABLE_CURL_MANUAL` by default Meaning `curl.1` and `src/tool_hugehelp.c` are built by default, and `--manual` in curl tool is also enabled by default. This syncs behaviour with autotools. For a reproducible `curl.1`, `SOURCE_DATE_EPOCH` needs to be set to a consistent date, e.g. the timestamp of `CHANGES`. A pre-built manual (e.g. the one distributed in the official source tarball) will be ignored and rebuilt after this patch, unless explicitly disabling this option.

When generating libcurl.pc and curl-config, getting libraries as full paths is unusual when one expects to get a list of -l. To meet expectations, an effort is made to convert the full paths into -l, possibly with -L before it. Fixes #6169 Fixes #12748 Closes #12930 Daniel Stenberg (7 Mar 2024) - test463: HTTP with -d @file with file containing CR, LF and null byte - paramhlp: fix CRLF-stripping files with "-d @file" All CR and LF bytes should be stripped, as documented, and all other bytes are inluded in the data. Starting now, it also excludes null bytes as they would otherwise also cut the data short. Reported-by: Simon K Fixes #13063 Closes #13064 Viktor Szakats (7 Mar 2024) - cmake: fix `CURL_WINDOWS_SSPI=ON` with Schannel disabled Prior to this change `CURL_WINDOWS_SSPI` was accidentally forced `OFF` when building without the Schannel TLS backend. This in turn may have caused Kerberos, SPNEGO and SSPI features disappearing even with `CURL_WINDOWS_SSPI=ON` set. This patch fixes it by using the `CURL_USE_SCHANNEL` setting as a default for `CURL_WINDOWS_SSPI`, but allowing a manual override. Also update the option text to better tell its purpose.

Closes #13045 Viktor Szakats (5 Mar 2024) - KNOWN_BUGS: fix typo Reviewed-by: Daniel Stenberg Closes #13051 Sebastian Neubauer (5 Mar 2024) - smpt: fix starttls In cases where the connection was fast, curl sometimes failed to open a connection. This fixes a regression of c2d973627bab12abc5486a3f3. The regression triggered in these steps: 1. Create an smtp connection 2. Use STARTTLS 3. Receive the response 4. We are inside the loop in `smtp_statemachine`, calling `smtp_state_starttls_resp` 5. In the good flow, we exit the loop, re-enter `smtp_statemachine` and run `smtp_perform_upgrade_tls` at the start of the function. In the bad flow, we stay in the while loop, calling `Curl_pp_readresp`, which reads part of the TLS handshake and things go wrong. The reason is that `Curl_pp_moredata` changed behavior and always returns `true`, so we stay in the loop in `smtp_statemachine`. With a slow connection `Curl_pp_readresp` cannot read new data and returns `CURL_AGAIN`, so we leave the loop and re-enter `smtp_statemachine`. With a fast connection, `Curl_pp_readresp` reads new data from the tcp connection, which is part of the TLS handshake. The fix is in `Curl_pp_moredata`, which needs to take the final line into account and return `false` if only the final line is stored.

This is independent of the request body size. Resolves #12938 as now small and large requests have the same code path. Changes done to test cases: - test513: now fails before sending request headers as this initial "client read" triggers the setup fault. Behaves now the same as in hyper build - test547, test555, test1620: fix the length check in the lib code to only fail for reads *smaller* than expected. This was a bug in the test code that never triggered in the old implementation.

When building for 32-bit ARM or x86 Android, `st_mode` is defined as `unsigned int` instead of `mode_t`, resulting in a `-Wimplicit-int-conversion` clang warning because `mode_t` is `unsigned short`. Add a cast to silence the warning, but only for 32-bit Android builds, because other architectures and platforms are not affected.

The send abstraction stack, to to bottom, now is: * `Curl_req_send()`: has parameter to indicate amount of header bytes, buffers all data. * `Curl_xfer_send()`: knows on which socket index to send, returns amount of bytes sent. * `Curl_conn_send()`: called with socket index, returns amount of bytes sent. In addition there is `Curl_req_flush()` for writing out all buffered bytes. `Curl_req_send()` is active for requests without body, `Curl_buffer_send()` still being used for others. This is because the special quirks need to be addressed in future parts: * `expect-100` handling * `Curl_fillreadbuffer()` needs to add directly to the new `data->req.sendbuf` * special body handlings, like `chunked` encodings and line end conversions will be moved into something like a Client Reader. In functions of the pattern `CURLcode xxx_send(..., ssize_t *written)`, replace the `ssize_t` with a `size_t`. It makes no sense to allow for negativ e values as the returned `CURLcode` already specifies error conditions. This allows easier handling of lengths without casting. Closes #12964 Daniel Stenberg (27 Feb 2024) - multi: make add_handle free any multi_easy If the easy handle that is being added to a multi handle has previously been used for curl_easy_perform(), there is a private multi handle here that we can kill off.

Closes https://github.com/curl/curl/pull/12911 - schannel: fix hang on unexpected server close - Treat TLS connection close (either due to a close_notify from the server or just closed due to receiving 0) as pending data.

In this case schannel_recv must be called again, which only happens if readwrite_data sees that there is still pending data. Prior to this change if the total size of the body that libcurl expected to receive from the server was unknown then it was possible under some network conditions that libcurl would hang waiting to receive more data, when in fact a close_notify alert indicating no more data would be sent was already processed.

Reported-by: Sergey Bronnikov Bug: https://curl.se/mail/lib-2024-02/0000.html Closes #12842 - ftp: treat a 226 arriving before data as a signal to read data For active mode transfers. Due to some interesting timing, curl can sometimes get the 226 (transfer complete) over the control channel first, before the data connection signals readability. If this happens, use that as a signal to check the data connection. Additionally, set the socket filter in listen mode *before* the PORT/EPRT command is issued, to reduce the risk that the little time gap could interfere.

Consider http authentication options which are mapped to SASL options as a default (overriding the hardcoded default mask for the protocol) that is ignored if a login option string is given. Prior to this change, if some HTTP auth options were given, sasl mapped http authentication options to sasl ones but merged them with the login options. That caused problems with the cli tool that sets the http login option CURLAUTH_BEARER as a side-effect of --oauth2-bearer, because this flag maps to more than one sasl mechanisms and the latter cannot be cleared individually by the login options string.

Closes #12753 Daniel Stenberg (23 Jan 2024) - mksymbolsmanpage.pl: provide references to where the symbol is used - docs: introduce "curldown" for libcurl man page format curldown is this new file format for libcurl man pages. It is markdown inspired with differences: - Each file has a set of leading headers with meta-data - Supports a small subset of markdown - Uses .md file extensions for editors/IDE/GitHub to treat them nicely - Generates man pages very similar to the previous ones - Generates man pages that still convert nicely to HTML on the website - Detects and highlights mentions of curl symbols automatically (when their man page section is specified) tools: - cd2nroff: converts from curldown to nroff man page - nroff2cd: convert an (old) nroff man page to curldown - cdall: convert many nroff pages to curldown versions - cd2cd: verifies and updates a curldown to latest curldown This setup generates .3 versions of all the curldown versions at build time. CI: Since the documentation is now technically markdown in the eyes of many things, the CI runs many more tests and checks on this documentation, including proselint, link checkers and tests that make sure we capitalize the first letter after a period...

This requires the nghttp3 library - implementation with the following restrictions: * macOS has to use an unconnected UDP socket due to an issue in OpenSSL's datagram implementation See https://github.com/openssl/openssl/issues/23251 This makes connections to non-reponsive servers hang. * GET requests will send the indicator that they have no body in a separate QUIC packet.

That's a problem if the string also contains a = sign because then it is documented to be interpreted as a cookie string and not a filename. Example: `--cookie @foo=bar` Before: Interpreted as load cookies from filename foo=bar. After: Interpreted as cookie `@foo=bar` (name `@foo` and value `bar`). Other curl options with a data/filename option-value use the `@filename` to distinguish filenames which is probably how this happened. The --cookie option has never been documented that way.

This concerns mainly HTTP and its bastard sibling RTSP. The terms "read" and "write" are often used without clear context if they refer to the connect or the client/application side of a transfer. This PR uses "read/write" for operations on the client side and "send/receive" for the connection, e.g. server side. If this is considered useful, we can revisit renaming of further methods in another PR. Curl's protocol handler `readwrite()` method been changed: ```diff - CURLcode (*readwrite)(struct Curl_easy *data, struct connectdata *conn, - const char *buf, size_t blen, - size_t *pconsumed, bool *readmore); + CURLcode (*write_resp)(struct Curl_easy *data, const char *buf, size_t ble n, + bool is_eos, bool *done); ``` The name was changed to clarify that this writes reponse data to the client side. The parameter changes are: * `conn` removed as it always operates on `data->conn` * `pconsumed` removed as the method needs to handle all data on success * `readmore` removed as no longer necessary * `is_eos` as indicator that this is the last call for the transfer response (end-of-stream). * `done` TRUE on return iff the transfer response is to be treated as finished This change affects many files only because of updated comments in handlers that provide no implementation. The real change is that the HTTP protocol handlers now provide an implementation. The HTTP protocol handlers `write_resp()` implementation will get passed **all** raw data of a server response for the transfer. The HTTP/1.x formatted status and headers, as well as the undecoded response body. `Curl_http_write_resp_hds()` is used internally to parse the response headers and pass them on. This method is public as the RTSP protocol handler also uses it. HTTP/1.1 "chunked" transport encoding is now part of the general *content encoding* writer stack, just like other encodings. A new flag `CLIENTWRITE_EOS` was added for the last client write. This allows writers to verify that they are in a valid end state. The chunked decoder will check if it indeed has seen the last chunk. The general response handling in `transfer.c:466` happens in function `readwrite_data()`. This mainly operates now like: ``` static CURLcode readwrite_data(data, ...) { do { Curl_xfer_recv_resp(data, buf) ... Curl_xfer_write_resp(data, buf) ... } while(interested); ... } ``` All the response data handling is implemented in `Curl_xfer_write_resp()`. It calls the protocol handler's `write_resp()` implementation if available, or does the default behaviour. All raw response data needs to pass through this function. Which also means that anyone in possession of such data may call `Curl_xfer_write_resp()`.

This makes it unnecessary to make a mingw-specific trick and pull all Windows headers early just for this type definition. This type is specific to Windows, not to the compiler. mingw-w64's Windows header maps it to `int` too. With this we also delete all remaining uses of `CURL_PULL_WS2TCPIP_H`.

A: With CMake, since 2ebc74c36a19a1700af394c16855ce144d9878e3 #11546 and fc9bfb14520712672b4784e8b48256fb29204011 #11627, we explicitly enable PIC for libcurl shared lib. Or when building libcurl for shared and static lib in a single pass. We do this by default for Windows or when enabled by the user via `SHARE_LIB_OBJECT`. Otherwise we don't touch this setting. Meaning the default set by CMake (if any) or the toolchain is used. On Debian Bookworm, this means that PIC is disabled for static libs by default. Some platforms (like macOS), has PIC enabled by default. autotools supports the double-pass mode only, and in that case CMake seems to match PIC behaviour now (as tested on Linux with gcc.)

Answering one of questions: Q: "The gcc command line use neither -g nor any -O options. As a developer, I also treasure our configure scripts's --enable-debug option that sets a long range of "picky" compiler options." A: CMake offers the `CMAKE_BUILD_TYPE` variable to control debug info and optimization level. E.g.: - `Release` = `-O3` + no debug info - `MinSizeRel` = `-Os` + no debug info - `Debug` = `-O0` + debug info https://stackoverflow.com/questions/48754619/what-are-cmake-build-type-deb ug-release-relwithdebinfo-and-minsizerel/59314670#59314670 https://cmake.org/cmake/help/latest/manual/cmake-buildsystem.7.html#defaul t-and-custom-configurations For picky warnings we have the `PICKY_COMPILER` options, enabled by default.

In both cases libcurl would fall back on unsigned short as the address family type, which is the same as ADDRESS_FAMILY.

Reviewed-by: Dan Fandrich Reviewed-by: Jay Satiro Closes #12378 - windows: use built-in `_WIN32` macro to detect Windows Windows compilers define `_WIN32` automatically. Windows SDK headers or build env defines `WIN32`, or we have to take care of it. The agreement seems to be that `_WIN32` is the preferred practice here. Make the source code rely on that to detect we're building for Windows. Public `curl.h` was using `WIN32`, `__WIN32__` and `CURL_WIN32` for Windows detection, next to the official `_WIN32`. After this patch it only uses `_WIN32` for this. Also, make it stop defining `CURL_WIN32`. There is a slight chance these break compatibility with Windows compilers that fail to define `_WIN32`. I'm not aware of any obsolete or modern compiler affected, but in case there is one, one possible solution is to define this macro manually. grepping for `WIN32` remains useful to discover Windows-specific code. Also: - extend `checksrc` to ensure we're not using `WIN32` anymore. - apply minor formatting here and there. - delete unnecessary checks for `!MSDOS` when `_WIN32` is present.

This suggests this may not be needed anymore, but if it does, we may restore this for those specific (non-Windows) systems. - lib: delete unused macro `FTP_BUFFER_ALLOCSIZE` since c1d6fe2aaa5a26e49a69a4f2495b3cc7a24d9394. - lib: delete unused macro `isxdigit_ascii` since f65f750742068f579f4ee6d8539ed9d5f0afcb85. - lib/mqtt: delete unused macro `MQTT_HEADER_LEN`. - lib/multi: delete unused macro `SH_READ`/`SH_WRITE`. - lib/hostip: add `noreturn` function attribute via new `CURL_NORETURN` macro. - lib/mprintf: delete duplicate declaration for `Curl_dyn_vprintf`. - lib/rand: fix `-Wunreachable-code` and related fallouts [3]. - lib/setopt: fix `-Wunreachable-code-break`. - lib/system_win32 and lib/timeval: fix double declarations for `Curl_freq` and `Curl_isVistaOrGreater` in CMake UNITY mode [4]. - lib/warnless: fix double declarations in CMake UNITY mode [5]. This was due to force-disabling the header guard of `warnless.h` to to reapply it to source code coming after `warnless.c` in UNITY builds. This reapplied declarations too, causing the warnings. Solved by adding a header guard for the lines that actually need to be reapplied. - lib/vauth/digest: fix `-Wunreachable-code-break` [6]. - lib/vssh/libssh2: fix `-Wunreachable-code-break` and delete redundant block. - lib/vtls/sectransp: fix `-Wunreachable-code-break` [7]. - lib/vtls/sectransp: suppress `-Wunreachable-code`. Detected in `else` branches of dynamic feature checks, with results known at compile-time, e.g. ```c if(SecCertificateCopySubjectSummary) /* -> true */ ``` Likely fixable as a separate micro-project, but given SecureTransport is deprecated anyway, let's just silence these locally. - src/tool_help: delete duplicate declaration for `helptext`. - src/tool_xattr: fix `-Wunreachable-code`. - tests: delete duplicate declaration for `unitfail` [8]. - tests: delete duplicate declaration for `strncasecompare`. - tests/libtest: delete duplicate declaration for `gethostname`.

However, building the clientconn requires resending the HTTP/2 connection preface, which is incorrect from a protocol perspective. That in turn causes servers to send GOAWAY frames, effectively degrading performance to "no connection reuse" in the best case. It may also be triggering some bugs where requests get dropped entirely and reconnects take too long. This doesn't rule out HTTP/2 support with Hyper, but it may take a redesign of the Hyper integration in order to make things work.

This works fine because the set of schemes is known and cannot change in a build. The hash algorithm and table size is made to only make a single scheme index per table entry. The perfect hash is generated by a separate tool (scripts/schemetable.c) Closes #12347 - scripts: add schemetable.c This tool generates a scheme-matching table. It iterates over a number of different initial and shift values in order to find the hash algorithm that needs the smallest possible table. The generated hash function, table and table size then needs to be used by the url.c:Curl_getn_scheme_handler() function.

Because the value is not strictly set with a setopt option. 2. Because otherwise when duping a handle when all the set.* fields are first copied and an error happens (think out of memory mid-function), the function would easily free the list *before* it was deep-copied, which could lead to a double-free. Closes #12323 Viktor Szakats (14 Nov 2023) - autotools: avoid passing `LDFLAGS` twice to libcurl autotools passes `LDFLAGS` automatically linker commands. curl's `lib/Makefile.am` customizes libcurl linker flags. In that customization, it added `LDFLAGS` to the custom flags. This resulted in passing `LDFLAGS` _twice_ to the `libtool` command. Most of the time this is benign, but some `LDFLAGS` options can break the build when passed twice. One such example is passing `.o` files, e.g. `crt*.o` files necessary when customizing the C runtime, e.g. for MUSL builds. Passing them twice resulted in duplicate symbol errors: ``` libtool: link: clang-15 --target=aarch64-unknown-linux-musl [...] /usr/lib/a arch64-linux-musl/crt1.o [...] /usr/lib/aarch64-linux-musl/crt1.o [...] ld.lld-15: error: duplicate symbol: _start >>> defined at crt1.c >>> /usr/lib/aarch64-linux-musl/crt1.o:(.text+0x0) >>> defined at crt1.c >>> /usr/lib/aarch64-linux-musl/crt1.o:(.text+0x0) [...] clang: error: linker command failed with exit code 1 (use -v to see invocatio n) ``` This behaviour came with commit 1a593191c2769a47b8c3e4d9715ec9f6dddf5e36 (2013-07-23) as a fix for bug https://curl.haxx.se/bug/view.cgi?id=1217. The patch was a works-for-me hack that ended up merged in curl: https://sourceforge.net/p/curl/bugs/1217/#06ef With the root cause remaining unclear. Perhaps the SUNPro 12 linker was sensitive to `-L` `-l` order, requiring `-L` first? This would be unusual and suggests a bug in either the linker or in `libtool`. The curl build does pass the list of detected libs via its own `LIBCURL_LIBS` variable, which ends up before `LDFLAGS` on the `libtool` command line, but it's the job of `libtool` to ensure that even a peculiar linker gets the options in the expected order. Also because autotools passes `LDFLAGS` last, making it hardly possible to pass anything after it. Perhaps in the 10 years since this issue, this already got a fix upstream. This patch deletes `LDFLAGS` from our customized libcurl options, leaving a single copy of them as passed by autotools automatically. Reverts 1a593191c2769a47b8c3e4d9715ec9f6dddf5e36 Closes #12310 - autotools: accept linker flags via `CURL_LDFLAGS_{LIB,BIN}` To allow passing `LDFLAGS` specific to libcurl (`CURL_LDFLAGS_LIB`) and curl tool (`CURL_LDFLAGS_BIN`). This makes it possible to build libcurl and curl with a single invocation with lib- and tool-specific custom linker flags. Such flag can be enabling `.map` files, a `.def` file for libcurl DLL, controlling static/shared, incl. requesting a static curl tool (with `-static-libtool-libs`) while building both shared and static libcurl. curl-for-win uses the above and some more. These options are already supported in `Makefile.mk`. CMake has built-in variables for this. Closes #12312 Jay Satiro (14 Nov 2023) - tool_cb_hdr: add an additional parsing check - Don't dereference the past-the-end element when parsing the server's Content-disposition header. As 'p' is advanced it can point to the past-the-end element and prior to this change 'p' could be dereferenced in that case. Technically the past-the-end element is not out of bounds because dynbuf (which manages the header line) automatically adds a null terminator to every buffer and that is not included in the buffer length passed to the header callback.

Switch that to `opensslv.h`. This wasn't causing a deeper problem because the code is looking for v3, which is only provided by OpenSSL/quictls as of now. According to https://github.com/openssl/openssl/issues/17517, the macro `OPENSSL_VERSION_NUMBER` is safe to use and not deprecated.

It means that any of these features make curl require a C99 compiler. (In case of MSVC, this means Visual Studio 2010 or newer.) This patch changes the single use of `stdint.h` guarded by `HAVE_STDINT_H` to use `stdint.h` unconditionally.

One dependency, LibreSSL, happens to publish an `arc4random` function (via its shared lib before v3.7, also via static lib as of v3.8.2). When trying to use this function in `lib/rand.c`, its protoype is missing. To fix that, curl included a prototype, but that used a C99 type without including `stdint.h`, causing: ``` ../../lib/rand.c:37:1: error: unknown type name 'uint32_t' 37 | uint32_t arc4random(void); | ^ 1 error generated. ``` This patch improves this by dropping the local prototype and instead limiting `arc4random` use for non-OpenSSL builds. OpenSSL builds provide their own random source anyway. The better fix would be to teach autotools to not link dependency libs while detecting `arc4random`.

This caused disabling support for this unless specifying the value manually. Restore this header and update its comment to tell why we continue to need it.

We enabled them unconditionally (with `ENABLE_THREADED_RESOLVER`). CMake built-in thread detection logic has this condition hard-coded for Windows as well (since at least 2007). Instead of doing all the work of detecting pthread combinations on Windows, then discarding those results, skip these efforts and assume built-in thread support when building for Windows. This saves 1-3 slow CMake configuration steps. Reviewed-by: Daniel Stenberg Closes #12202 - cmake: speed up zstd detection Before this patch we detected the presence of a specific zstd API to see if we can use the library. zstd published that API in its first stable release: v1.0.0 (2016-08-31). Replace that method by detecting the zstd library version instead and accepting if it's v1.0.0 or newer. Also display this detected version and display a warning if the zstd found is unfit for curl. We use the same version detection method as zstd itself, via its public C header. This deviates from autotools which keeps using the slow method of looking for the API by building a test program. The outcome is the same as long as zstd keeps offering this API.

These, depending on transfer state (CONNECT/DO/DONE/ etc.), return sockets to monitor and flag if this shall be done for POLLIN and/or POLLOUT. Due to this design, sockets and flags could only be added, not removed. This led to problems in filters like HTTP/2 where flow control prohibits the sending of data until the peer increases the flow window. The general transfer loop wants to write, adds POLLOUT, the socket is writeable but no data can be written. This leads to cpu busy loops. To prevent that, HTTP/2 did set the `SEND_HOLD` flag of such a blocked transfer, so the transfer loop cedes further attempts. This works if only one such filter is involved. If a HTTP/2 transfer goes through a HTTP/2 proxy, two filters are setting/clearing this flag and may step on each other's toes. Connection filters `get_select_socks()` is replaced by `adjust_pollset()`. They get passed a `struct easy_pollset` that keeps up to `MAX_SOCKSPEREASYHANDLE` sockets and their `POLLIN|POLLOUT` flags. This struct is initialized in `multi_getsock()` by calling the various `getsocks()` implementations based on transfer state, as before. After protocol handlers/transfer loop have set the sockets and flags they want, the `easy_pollset` is *always* passed to the filters. Filters "higher" in the chain are called first, starting at the first not-yet-connection one. Each filter may add sockets and/or change flags. When all flags are removed, the socket itself is removed from the pollset. Example: * transfer wants to send, adds POLLOUT * http/2 filter has a flow control block, removes POLLOUT and adds POLLIN (it is waiting on a WINDOW_UPDATE from the server) * TLS filter is connected and changes nothing * h2-proxy filter also has a flow control block on its tunnel stream, removes POLLOUT and adds POLLIN also. * socket filter is connected and changes nothing * The resulting pollset is then mixed together with all other transfers and their pollsets, just as before. Use of `SEND_HOLD` is no longer necessary in the filters. All filters are adapted for the changed method. The handling in `multi.c` has been adjusted, but its state handling the the protocol handlers' `getsocks` method are untouched. The most affected filters are http/2, ngtcp2, quiche and h2-proxy. TLS filters needed to be adjusted for the connecting handshake read/write handling. No noticeable difference in performance was detected in local scorecard runs.

Closes #12193 Viktor Szakats (24 Oct 2023) - cmake: pre-fill rest of detection values for Windows The goal of this patch is to avoid unnecessary feature detection work when doing Windows builds with CMake. Do this by pre-filling well-known detection results for Windows and specifically for mingw-w64 and MSVC compilers. Also limit feature checks to platforms where the results are actually used. Drop a few redundant ones. And some tidying up. - pre-fill remaining detection values in Windows CMake builds. Based on actual detection results observed in CI runs, preceding similar work over libssh2 and matching up values with `lib/config-win32.h`. This brings down CMake configuration time from 58 to 14 seconds on the same local machine. On AppVeyor CI this translates to: - 128 seconds -> 50 seconds VS2022 MSVC with OpenSSL (per CMake job): https://ci.appveyor.com/project/curlorg/curl/builds/48208419/job/4gw66ecr jpy7necb#L296 https://ci.appveyor.com/project/curlorg/curl/builds/48217440/job/8m4fwrr2 fe249uo8#L186 - 62 seconds -> 16 seconds VS2017 MINGW (per CMake job): https://ci.appveyor.com/project/curlorg/curl/builds/48208419/job/s1y8q5iv lcs7ub29?fullLog=true#L290 https://ci.appveyor.com/project/curlorg/curl/builds/48217440/job/pchpxyjs yc9kl13a?fullLog=true#L194 The formula is about 1-3 seconds delay for each detection. Almost all of these trigger a full compile-link cycle behind the scenes, slow even today, both cross and native, mingw-w64 and apparently MSVC too. Enabling .map files or other custom build features slows it down further. (Similar is expected for autotools configure.) - stop detecting `idn2.h` if idn2 was deselected. autotools does this. - stop detecting `idn2.h` if idn2 was not found. This deviates from autotools. Source code requires both header and lib, so this is still correct, but faster. - limit `ADDRESS_FAMILY` detection to Windows. - normalize `HAVE_WIN32_WINNT` value to lowercase `0x0a12` format. - pre-fill `HAVE_WIN32_WINNT`-dependent detection results. Saving 4 (slow) feature-detections in most builds: `getaddrinfo`, `freeaddrinfo`, `inet_ntop`, `inet_pton` - fix pre-filled `HAVE_SYS_TIME_H`, `HAVE_SYS_PARAM_H`, `HAVE_GETTIMEOFDAY` for mingw-w64. Luckily this do not change build results, as `WIN32` took priority over `HAVE_GETTIMEOFDAY` with the current source code. - limit `HAVE_CLOCK_GETTIME_MONOTONIC_RAW` and `HAVE_CLOCK_GETTIME_MONOTONIC` detections to non-Windows. We're not using these in the source code for Windows. - reduce compiler warning noise in CMake internal logs: - fix to include `winsock2.h` before `windows.h`. Apply it to autotools test snippets too. - delete previous `-D_WINSOCKAPI_=` hack that aimed to fix the above. - cleanup `CMake/CurlTests.c` to emit less warnings. - delete redundant `HAVE_MACRO_SIGSETJMP` feature check. It was the same check as `HAVE_SIGSETJMP`. - delete 'experimental' marking from `CURL_USE_OPENSSL`. - show CMake version via `CMakeLists.txt`. Credit to the `zlib-ng` project for the idea: https://github.com/zlib-ng/zlib-ng/blob/61e181c8ae93dbf56040336179c9954078b d1399/CMakeLists.txt#L7 - make `CMake/CurlTests.c` pass `checksrc`. - `CMake/WindowsCache.cmake` tidy-ups. - replace `WIN32` guard with `_WIN32` in `CMake/CurlTests.c`.

This caused problems when detecting components with unnecessary dependencies that were not yet built. CMake offers the `CMAKE_REQUIRED_LIBRARIES` variable to set libs used for component checks, which we already use in most cases. That left 4 uses of `check_library_exists_concat()`. Only one of these actually needed the 'concat' feature (ldap/lber). Delete this function and replace it with standard `check_library_exists()` and manual management of our `CURL_LIBS` list we use when linking build targets. And special logic to handle the ldap/lber case. (We have a similar function for headers: `check_include_file_concat()`. It works, but problematic for performance reasons and because it hides the actual headers required in `check_symbol_exists()` calls.)

The one use of `HAVE_BORINGSSL` in the source turned out to be no longer necessary for warning-free BoringSSL + Schannel builds. Ref: #1610 #2634 autotools detects this anyway for display purposes.

We must make sure that the `memdebug.h` header doesn't apply to `lib/curl_multibyte.c` (as even noted in a comment there.) In unity builds all headers apply to all sources, including `curl_multibyte.c`. This probably resulted in an infinite loop on startup. Exclude this source from unity compilation with TrackMemory enabled, in both libcurl and curl tool. Enable unity mode for a debug Unicode CI job to keep it tested. Also delete the earlier workaround that fully disabled unity for affected builds.

There is an issue with memory tracking and Unicode when built in "unity" mode, which results in the curl tool crashing right on startup, even without any command-line option. Interestingly this doesn't happen under WINE (at least on the system I tested this on), but consistenly happens on real Windows machines. Crash is 0xC0000374 heap corruption. Both shared and static curl executables are affected. This limitation probably won't hit too many people, but it remains a TODO to find and fix the root cause and drop this workaround.

Rewrite in PowerShell: - rewrite MS-DOS batch build script in PowerShell. - move some bash operations into native PowerShell. - fixups for PowerShell insisting on failure when a command outputs something to stderr. - fix to actually run `curl -V` after every build. (and exclude ARM64 builds.) - also say why we skipped `curl -V` if we had to skip. - fix CMake warnings about unused configuration variables, by adapting these dynamically for build cases. - dedupe OpenSSL path into a variable. - disable `test1451` failing with a warning anyway due to missing python impacket. (after trying and failing to install impacket) PowerShell promotes these warnings to errors by PowerShell. We can also suppress they wholesale if they start causing issues in the future, like we already to with `autoreconf` and `./configure`. PowerShell is better than MS-DOS batches, so the hope is this makes it easier to extend and maintain the AppVeyor build logic. POSIX/bash isn't supported inline by AppVeyor on Windows build machines, but we are okay to keep it in an external script, so it's also an option. 2. CI improvements: - enable tests for a "unity" build job. - speed-up CI initialization by using shallow clones of the curl repo. - speed-up CMake MSVC jobs with `TrackFileAccess=false`. - enable parallelism in `VisualStudioSolution` builds. - display CMake version before builds. - always show the CPU in job names. - tell which jobs are build-only in job names. - move `TESTING:` value next to `DISABLED_TESTS:` in two jobs. - add `config.log` (autotools) to dumped logs (need to enable manually). 3. Style: - use single-quotes in YAML like we do in other CI YAML files. It also allows to drop quoting characters and lighter to write/read. (keep double quotes for PowerShell strings needing expansion.) Closes #11999 - cmake: fix `HAVE_LDAP_SSL`, `HAVE_LDAP_URL_PARSE` on non-Windows - set `HAVE_LDAP_URL_PARSE` if `ldap_url_parse` function exists. Before this patch we set it based it on the presence of `stricmp`, which correctly enabled it on e.g. Windows, but was inaccurate for other platforms. - always set `HAVE_LDAP_SSL` if an LDAP backend is detected and LDAPS is not explicitly disabled. This mimics autotools behaviour. Previously we set it only for Windows LDAP. After this fix, LDAPS is correctly enabled in default macOS builds. - enable LDAP[S] for a CMake macOS CI job. Target OS X 10.9 (Mavericks) to avoid deprecation warnings for LDAP API. - always detect `HAVE_LDAP_SSL_H`, even with LDAPS explicitly disabled. This doesn't make much sense, but let's do it to sync behaviour with autotools. - fix benign typo in variable name. Ref: #11964 (effort to sync cmake detections with autotools) Closes #12006 - autotools: restore `HAVE_IOCTL_*` detections This restores `CURL_CHECK_FUNC_IOCTL` detection.

But, I did miss the fact that this had two dependent checks: `CURL_CHECK_FUNC_IOCTL_FIONBIO`, `CURL_CHECK_FUNC_IOCTL_SIOCGIFADDR` that we do actually need: `HAVE_IOCTL_FIONBIO`, `HAVE_IOCTL_SIOCGIFADDR`.

In CMake we assume we're running on newer systems and enable regardless of OS version. autotools always runs all 3 probes for non-fast-tracked systems and enables this feature if any one of them was successful.

At the end of a test run, if results haven't come in within a couple of minutes, display the status of all test runners and what tests they're running to help in debugging the problem.

To match existing option and detection logic in autotools. Also: - fix detecting GnuTLS. We assume `nettle` as a GnuTLS dependency. - add CMake GnuTLS CI job. - bump AppVeyor CMake OpenSSL MSVC job to OpenSSL 1.1.1 (from 1.0.2) TLS-SRP fails to detect with 1.0.2 due to an OpenSSL header bug. - fix compiler warning when building with GnuTLS and disabled TLS-SRP. - fix comment typos, whitespace. Ref: #11964 Closes #11967 - tool: use our own stderr variable Earlier this year we changed our own stderr variable to use the standard name `stderr` (to avoid bugs where someone is using `stderr` instead of the curl-tool specific variable). This solution needed to override the standard `stderr` symbol via the preprocessor. This in turn didn't play well with unity builds and caused curl tool to crash or stay silent due to an uninitialized stderr. This was a hard to find issue, fixed by manually breaking out one file from the unity sources. To avoid two these two tricks, this patch implements a different solution: Restore using our own local variable for our stderr output and leave `stderr` as-is. To avoid using `stderr` by mistake, add a `checksrc` rule (based on logic we already used in lib for `strerror`) that detects any `stderr` use in `src` and points to using our own variable instead: `tool_stderr`.

If "src[i] << (1 - i % 2 << 3)" is greater than 0x7FFFFFFF, the upper bits of the result will all be 1. 111 words[i/2] |= (src[i] << ((1 - (i % 2)) << 3)); The value will not be greater than 0x7FFFFFFF so this still cannot happen. Also, switch to ints here instead of longs. The values stored are 16 bit so at least no need to use 64 bit variables. Also, longs are 32 bit on some platforms so this logic still needs to work with 32 bits.

Follow-up to dd12b452a Closes #11906 - github/labeler: fix indenting to try to appease labeller Follow-up to dd12b452a Jay Satiro (21 Sep 2023) - libssh2: fix error message on failed pubkey-from-file - If libssh2_userauth_publickey_fromfile_ex returns -1 then show error message "SSH public key authentication failed: Reason unknown (-1)". When libssh2_userauth_publickey_fromfile_ex returns -1 it does so as a generic error and therefore doesn't set an error message. AFAICT that is not documented behavior. Prior to this change libcurl retrieved the last set error message which would be from a previous function failing. That resulted in misleading auth failed error messages in verbose mode. Bug: https://github.com/curl/curl/issues/11837#issue-1891827355 Reported-by: consulion@users.noreply.github.com Closes https://github.com/curl/curl/pull/11881 Stefan Eissing (21 Sep 2023) - pytest: exclude test_03_goaway in CI runs due to timing dependency Closes #11860 - lib: disambiguate Curl_client_write flag semantics - use CLIENTWRITE_BODY *only* when data is actually body data - add CLIENTWRITE_INFO for meta data that is *not* a HEADER - debug assertions that BODY/INFO/HEADER is not used mixed - move `data->set.include_header` check into Curl_client_write so protocol handlers no longer have to care - add special in FTP for `data->set.include_header` for historic, backward compatible reasons - move unpausing of client writes from easy.c to sendf.c, so that code is in one place and can forward flags correctly Closes #11885 Patrick Monnerat (21 Sep 2023) - tftpd: always use curl's own tftp.h Using the system's provided arpa/tftp.h and optimizing, GCC 12 detects and reports a stringop-overread warning: tftpd.c: In function ‘write_behind.isra’: tftpd.c:485:12: warning: ‘write’ reading between 1 and 2147483647 bytes f rom a region of size 0 [-Wstringop-overread] 485 | return write(test->ofile, writebuf, count); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ In file included from tftpd.c:71: /usr/include/arpa/tftp.h:58:30: note: source object ‘tu_data’ of size 0 58 | char tu_data[0]; /* data or error stri ng */ | ^~~~~~~ This occurs because writebuf points to this field and the latter cannot be considered as being of dynamic length because it is not the last field in the structure. Thus it is bound to its declared size. This commit always uses curl's own version of tftp.h where the target field is last in its structure, effectively avoiding the warning. As HAVE_ARPA_TFTP_H is not used anymore, cmake/configure checks for arpa/tftp.h are removed. Closes #11897 Dan Fandrich (20 Sep 2023) - test1474: make precheck more robust on non-Solaris systems If uname -r returns something odd, perl could return an error code and the test would be erroneously skipped.

Reported-by: calvin2021y on github Fixes #11864 Closes #11869 Dan Fandrich (16 Sep 2023) - http_aws_sigv4: fix sorting with empty parts When comparing with an empty part, the non-empty one is always considered greater-than. Previously, the two would be considered equal which would randomly place empty parts amongst non-empty ones. This showed as a test 439 failure on Solaris as it uses a different implementation of qsort() that compares parts differently. Fixes #11855 Closes #11868 - CI: ignore the "flaky" and "timing-dependent" test results CI builds will now run these tests, but will ignore the results if they fail. The relevant tests are ones that are sensitive to timing or have edge conditions that make them more likely to fail on CI servers, which are often heavily overloaded and slow. This change only adds two additional tests to be ignored, since the others already had the flaky keyword. Closes #11865 - runtests: eliminate a warning on old perl versions The warning "Use of implicit split to @_ is deprecated" showed between perl versions about 5.8 through 5.11. - tests: log the test result code after each libtest This makes it easier to determine the test status. Also, capitalize FAILURE and ABORT messages in log lines to make them easier to spot. Harry Sintonen (16 Sep 2023) - misc: better random strings Generate alphanumerical random strings. Prior this change curl used to create random hex strings. This was mostly okay, but having alphanumerical random strings is better: The strings have more entropy in the same space. The MIME multipart boundary used to be mere 64-bits of randomness due to being 16 hex chars. With these changes the boundary is 22 alphanumerical chars, or little over 130 bits of randomness. Closes #11838 Daniel Stenberg (15 Sep 2023) - cookie: reduce variable scope, add const - cookie: do not store the expire or max-age strings Convert it to an expire time at once and save memory. Closes #11862 - cookie: remove unnecessary struct fields Plus: reduce the hash table size from 256 to 63. It seems unlikely to make much of a speed difference for most use cases but saves 1.5KB of data per instance. Closes #11862 - RELEASE-NOTES: synced Bumped to 8.4.0, the next presumed version Dan Fandrich (14 Sep 2023) - test2600: remove special case handling for USE_ALARM_TIMEOUT This was originally added to handle platforms that supported only 1 second granularity in connect timeouts, but after some recent changes the test currently permafails on several Windows platforms. The need for this special-case was removed in commit 8627416, which increased the connect timeout in all cases to well above 1 second. Fixes #11767 Closes #11849 Daniel Stenberg (14 Sep 2023) - SECURITY-PROCESS.md. call it vulnerability disclosure policy SECURITY-PROCESS.md -> VULN-DISCLOSURE-POLICY.md This a name commonly used for a document like this. This name helps users find it. Closes #11852 Junho Choi (14 Sep 2023) - quiche: fix build error with --with-ca-fallback - Fix build error when curl is built with --with-quiche and --with-ca-fallback. - Add --with-ca-fallback to the quiche CI job. Fixes https://github.com/curl/curl/issues/11850 Closes https://github.com/curl/curl/pull/11847 Jay Satiro (14 Sep 2023) - escape: replace Curl_isunreserved with ISUNRESERVED - Use the ALLCAPS version of the macro so that it is clear a macro is being called that evaluates the variable multiple times. - Also capitalize macro isurlpuntcs => ISURLPUNTCS since it evaluates a variable multiple times. This is a follow-up to 291d225a which changed Curl_isunreserved into an alias macro for ISUNRESERVED. The problem is the former is not easily identified as a macro by the caller, which could lead to a bug. For example, ISUNRESERVED(*foo++) is easily identifiable as wrong but Curl_isunreserved(*foo++) is not even though they both are the same. Closes https://github.com/curl/curl/pull/11846 Dan Fandrich (13 Sep 2023) - tests: increase the default server logs lock timeout This timeout is used to wait for the server to finish writing its logs before checking them against the expected values. An overloaded machine could take more than the two seconds previously allocated, so increase the timeout to 5 seconds. Ref: #11328 Closes #11834 - tests: increase TEST_HANG_TIMEOUT in two tests These tests had a 5 second timeout compared to 60 seconds for all other tests. Make these consistent with the others for more reliability on heavily-loaded machines. Ref: #11328 - test1056: disable on Windows This test relies on the IPv6 scope field being ignored when connecting to ipv6-localhost (i.e. [::1%259999] is treated as [::1]). Maybe this is a bit dodgy, but it works on all our test platforms except Windows. This test was disabled manually on all Windows CI builds already, so instead add an incompatible feature and precheck so it's skipped on Windows everywhere automatically. - test587: add a slight delay after test This test is designed to connect to the server, then immediately send a few bytes and disconnect. In some situations, such as on a loaded server, this doesn't give the server enough time to write its lock file before its existence is checked. The test harness then fails to find the server's input log file (because it hasn't been written yet) and fails the test. By adding a short delay after the test, the HTTP server has enough time to write its lock file which gives itself more time to write its remaining files. Ref: #11328 - tests: stop overriding the lock timeout These tests reduce the server lock wait timeout which can increase flakiness on loaded machines. Since this is merely an optimization, eliminate them in favour of reliability. Ref: #11328 - tests: add some --expect100-timeout to reduce timing dependencies These tests can fail when the test machine is so slow that the test HTTP server didn't get a chance to complete before the client's one second 100-continue timeout triggered. Increase that 1 second to 999 seconds so this situation doesn't happen. Ref: #11328 - test661: return from test early in case of curl error - tests: add the timing-dependent keyword on several tests These are ones likely to fail on heavily-loaded machines that alter the normal test timing. Most of these tests already had the flaky keyword since this condition makes them more likely to fail on CI. - test1592: greatly increase the maximum test timeout It was too short to be reliable on heavily loaded CI machines, and as a fail-safe only, it didn't need to be short. Ref: #11328 - test: minor test cleanups Remove an obsolete block of code in tests 2032 & 576. Add a comment in test 1474. - tests: quadruple the %FTPTIME2 and %FTPTIME3 timeouts This gives more of a margin for error when running on overloaded CI servers. Ref: #11328 - tests: improve SLOWDOWN test reliability by reducing sent data These tests are run in SLOWDOWN mode which adds a 10 msec delay after each character output, which means it takes at least 1.6 seconds (and 320 kernel calls) just to get through the long welcome banner. On an overloaded system, this can end up taking much more than 1.6 seconds, and even more than the 7 or 16 second curl timeout that the tests rely on, causing them to fail. Reducing the size of the welcome banner drops the total number of characters sent before the transfer starts by more than half, which reduces the opportunity for test-breaking slowdowns by the same amount.
