Reported-by: Hao Wu Fixes #5302 Closes #5303 - travis: bump the wolfssl CI build to use 4.4.0 Closes #5301 - copyright updates: adjust year ranges Marc Hoersken (26 Apr 2020) - CI: do not include */ci branches in PR builds Align Azure Pipelines with GitHub Actions. Daniel Stenberg (25 Apr 2020) - runtests: check for the disabled tests relative srcdir To make it work correctly for out-of-tree builds. Follow-up to 75e8feb6fb08b Bug: https://github.com/curl/curl/pull/5288#issuecomment-619346389 Reported-by: Marcel Raad Closes #5297 - runtests: revert commenting out a line I did for debugging Follow-up to 11091cd4d. It was not meant to be pushed! - smtp: set auth correctly Regression since 7.69.0 and 68fb25fa3fcff. The code wrongly assigned 'from' instead of 'auth' which probably was a copy and paste mistake from other code, leading to that auth could remain NULL and later cause an error to be returned. Assisted-by: Eric Sauvageau Fixes #5294 Closes #5295 Marcel Raad (25 Apr 2020) - lib: clean up whitespace This fixes CodeFactor warnings. Daniel Stenberg (25 Apr 2020) - [Anderson Toshiyuki Sasaki brought this change] libssh: avoid options override by configuration files Previously, options set explicitly through command line options could be overridden by the configuration files parsed automatically when ssh_connect() was called. By calling ssh_options_parse_config() explicitly, the configuration files are parsed before setting the options, avoiding the options override. Once the configuration files are parsed, the automatic configuration parsing is not executed. Fixes #4972 Closes #5283 Signed-off-by: Anderson Toshiyuki Sasaki <ansasaki@redhat.com> - runtests: when <killserver> mentions http, kill http/2 too Since the http2 test server is a mere proxy that needs to know about the dynamic port the HTTP server is using, it too needs to get restarted when the http server is killed. A regression caused by 80d6515. Fixes #5289 Closes #5291 - [Yuri Slobodyanyuk brought this change] docs: fix two typos Closes #5292 - [Emil Engler brought this change] tests/git: ignore mqttd and port files Closes #5290 - tests: make runtests check that disabled tests exists ... and error out if so. Removed '536' from DISABLED as there is no such test file. Closes #5288 - test1154: set a proper name - select: make Curl_socket_check take timediff_t timeout Coverity found CID 1461718: Integer handling issues (CONSTANT_EXPRESSION_RESULT) "timeout_ms > 9223372036854775807L" is always false regardless of the values of its operands. This occurs as the logical second operand of "||". Closes #5240 - [i-ky brought this change] libcurl-multi.3: added missing full stop Closes #5285 Jay Satiro (22 Apr 2020) - transfer: Switch PUT to GET/HEAD on 303 redirect Prior to this change if there was a 303 reply to a PUT request then the subsequent request to respond to that redirect would also be a PUT. It was determined that was most likely incorrect based on the language of the RFCs. Basically 303 means "see other" resource, which implies it is most likely not the same resource, therefore we should not try to PUT to that different resource. Refer to the discussions in #5237 and #5248 for more information. Fixes https://github.com/curl/curl/issues/5237 Closes https://github.com/curl/curl/pull/5248 Daniel Stenberg (22 Apr 2020) - lib/mk-ca-bundle: skip empty certs Reviewed-by: Emil Engler Reported-by: Ashwin Metpalli Fixes #5278 Closes #5280 - version: skip idn2_check_version() check and add precaution A gcc-10's -fanalyze complaint made me spot and do these improvements. Closes #5281 - RELEASE-NOTES: synced - [Brian Bergeron brought this change] curl.h: update comment typo "routines with be invoked" -> "routines will be invoked" Closes #5279 - [Emil Engler brought this change] GnuTLS: Don't skip really long certificate fields Closes #5271 - gnutls: bump lowest supported version to 3.1.10 GnuTLS 3.1.10 added new functions we want to use. That version was released on Mar 22, 2013. Removing support for older versions also greatly simplifies the code. Ref: #5271 Closes #5276 - mqtt: make NOSTATE get within the debug name array - tests: run the RTSP test server on a dynamic port number To avoid port collisions. Closes #5272 - tests: add %NOLISTENPORT and use it The purpose with this variable is to provide a port number that is reasonably likely to not have a listener on the local host so that tests can try connect failures against it. It uses port 47 - "reserved" according to IANA. Updated six tests to use it instead of the previous different ports. Assisted-by: Emil Engler Closes #5270 - mqtt: remove code with no purpose Detected by Coverity. CID 1462319. "The same code is executed when the condition result is true or false, because the code in the if-then branch and after the if statement is identical." Closes #5275 - mqtt: fix Curl_read() error handling while reading remaining length Detected by Coverity. CID 1462320. Closes #5274 - server/tftpd: fix compiler warning Follow-up from 369ce38ac1d Reported-by: Marc Hörsken - http: free memory when Alt-Used header creation fails due to OOM Reported-by: James Fuller Fixes #5268 Closes #5269 Daniel Gustafsson (20 Apr 2020) - lib: fix typos in comments and errormessages This fixes a few randomly spotted typos in recently merged code, most notably one in a userfacing errormessage the schannel code. Daniel Stenberg (20 Apr 2020) - tests: run the SOCKS test server on a dynamic port number Closes #5266 - [Johannes Schindelin brought this change] multi-ssl: reset the SSL backend on `Curl_global_cleanup()` When cURL is compiled with support for multiple SSL backends, it is possible to configure an SSL backend via `curl_global_sslset()`, but only *before* `curl_global_init()` was called. If another SSL backend should be used after that, a user might be tempted to call `curl_global_cleanup()` to start over. However, we did not foresee that use case and forgot to reset the SSL backend in that cleanup. Let's allow that use case. Fixes #5255 Closes #5257 Reported-by: davidedec on github Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> - tests: run the TFTP test server on a dynamic port number Picking a dynamic unused port is better than a fixed to avoid the collision risk. Closes #5265 - mqtt: improve the state machine To handle PUBLISH before SUBACK and more. Updated the existing tests and added three new ones. Reported-by: Christoph Krey Bug: https://curl.haxx.se/mail/lib-2020-04/0021.html Closes #5246 - runtests: always put test number in servercmd file - RELEASE-NOTES: synced - release-notes.pl: fix parsing typo James Fuller (20 Apr 2020) - [xquery brought this change] ensure all references to ports are replaced by vars - [xquery brought this change] add more alt-svc test coverage Daniel Stenberg (20 Apr 2020) - test1247: use http server to get the port number set Follow-up to 0f5db7b263f - runtests: use a unix domain socket path with the pid in the name To make it impossible for test cases to access the file name without using the proper variable for the purpose. Closes #5264 Daniel Gustafsson (19 Apr 2020) - [Tom brought this change] src: Remove C99 constructs to ensure C89 compliance This fixes the error: 'for' loop initial declaration used outside C99 mode by declaring the loop increment variable in the beginning of the block instead of inside the for loop. Fixes #5254 Reviewed-by: Daniel Gustafsson <daniel@yesql.se> Daniel Stenberg (19 Apr 2020) - runtests: dummy init the ports variables to avoid warnings ... and generate something that can help debug test cases. - [Patrick Monnerat brought this change] mime: properly check Content-Type even if it has parameters New test 669 checks this fix is effective. Fixes #5256 Closes #5258 Reported-by: thanhchungbtc on github - tests/FILEFORMAT: converted to markdown and extended Closes #5261 - test1245: make it work with dynamic FTP server port - test1055: make it work with dynamic FTP port - test1028: make it run on dynamic FTP server port - tests: move pingpong server to dynamic listening port FTP, IMAP, POP3, SMTP and their IPv6 versions are now all on dynamic ports Test 842-845 are unfortunately a bit hard to move over to this concept right now and require "default port" still... - test1056: work with dynamic HTTP ipv6 port - test1448: work with dynamic HTTP server port - tests: introduce preprocessed test cases The runtests script now always performs variable replacement on the entire test source file before the test gets executed, and saves the updated version in a temporary file (log/test[num]) so that all test case readers/servers can use that version (if present) and thus enjoy the powers of test case variable substitution. This is necessary to allow complete port number freedom. Test 309 is updated to work with a non-fixed port number thanks to this. - tests: make 2006-2010 handle different port number lengths - tests: run the sws server on "any port" Makes the test servers for HTTP and Gopher pop up on a currently unused port and runtests adapts to that! Closes #5247 Marc Hoersken (18 Apr 2020) - sockfilt: tidy variable naming and data structure in select_ws This commit does not introduce any logical changes to the code. Reviewed-by: Jay Satiro and Marcel Raad Closes #5238 Daniel Stenberg (17 Apr 2020) - [Anderson Toshiyuki Sasaki brought this change] libssh: Use new ECDSA key types to check known hosts From libssh 0.9.0, ssh_key_type() returns different key types for ECDSA keys depending on the curve. Signed-off-by: Anderson Toshiyuki Sasaki <ansasaki@redhat.com> Fixes #5252 Closes #5253 Marcel Raad (17 Apr 2020) - appveyor: add Unicode winbuild jobs These are cheap as they don't build tests. Closes https://github.com/curl/curl/pull/5063 Daniel Stenberg (16 Apr 2020) - mqttd: s/errno/SOCKERRNO To behave proper on Windows Reported-by: Gisle Vanem Bug: https://github.com/curl/curl/commit/5e855bbd18f84a02c951be7cac6188276818cdac#r38507132 Closes #5241 - buildconf: use find -execdir instead, remove -print and the ares files Follow-up to 1e41bec96a6e Suggested-by: Marc Hörsken - [Alexander V. Tikhonov brought this change] buildconf: avoid using tempfile when removing files Closes #5213 - copyright: bump the copyright year range - scripts/release-notes.pl: accept colon after the Fixes/Closes keywords - [JP Mens brought this change] docs/MQTT: replace confusing 80 by 75 I was a bit surprised by the `80`: first thought: what's HTTP doing here? ;) Closes #5236 - [Brad King brought this change] cmake: Avoid MSVC C4273 warnings in send/recv checks We use `check_c_source_compiles` to check possible send/recv signatures by reproducing the forward declarations from system headers. On Windows the `winsock2.h` header adds dll linkage settings to its forward declaration. If ours does not match the compiler warns: warning C4273: 'recv': inconsistent dll linkage Add `WINSOCK_API_LINKAGE` to our test signatures when it is defined so that our linkage is consistent with that from `winsock2.h`. Fixes #4764 Closes #5232 Jay Satiro (14 Apr 2020) - KNOWN_BUGS: Add entry 'Blocking socket operations' - Add threaded resolver cleanup and GSSAPI for FTP to the TODO list of known blocking operations. - New known bugs entry 'Blocking socket operations in non-blocking API' that directs to the TODO's list of known blocking operations. Ref: https://github.com/curl/curl/pull/5214#issuecomment-612488021 Reported-by: Marc Hoersken Closes https://github.com/curl/curl/pull/5216 Marc Hoersken (14 Apr 2020) - test2043: use revoked.badssl.com instead of revoked.grc.com The certificate of revoked.grc.com has expired on 2020-04-13. Reviewed-by: Jay Satiro Closes #5233 - sockfilt: fix broken pipe on Windows to be ready in select_ws Closes #5228 Daniel Stenberg (14 Apr 2020) - RELEASE-NOTES: synced - scripts/release-notes: fix duplicate output header - github/workflow: enable MQTT in the macOS debug build - azure: add mqtt support to one of the Windows builds - travis: add mqtt job on Linux - tests: add four MQTT tests 1190 - 1193 - tests: add the mqtt test server mqttd - tests: support hex encoded data and mqtt server The mqtt server is started using a "random" port. - [Björn Stenberg brought this change] mqtt: add new experimental protocol Closes #5173 - TODO: Consider convenience options for JSON and XML? Closes #5203 - tool: do not declare functions with Curl_ prefix To avoid collision risks with private libcurl symbols when linked with static versions (or just versions not hiding internal symbols). Reported-by: hydra3333 on github Fixes #5219 Closes #5234 - [Nathaniel R. Lewis brought this change] cmake: add aliases so exported target names are available in tree Reviewed-by: Brad King Closes #5206 - version: increase buffer space for ssl version output To avoid it getting truncated, especially when several SSL backends are built-in. Reported-by: Gisle Vanem Fixes #5222 Closes #5226 Marc Hoersken (13 Apr 2020) - cirrus: no longer ignore test 504 which is working again The test is working again, because TCP blackholing is disabled. - appveyor: completely disable tests that fail to timeout early The tests changed from ignored to disabled are tests that are about connecting to non-listening socket. On AppVeyor these tests are not reliable, because for some unknown reason the connect is not timing out before the test time limit is reached. Daniel Stenberg (13 Apr 2020) - test1908: avoid using fixed port number in test data Closes #5225 Jay Satiro (12 Apr 2020) - [Andrew Kurushin brought this change] schannel: Fix blocking timeout logic - Fix schannel_send for the case when no timeout was set. Prior to this change schannel would error if the socket was not ready to send data and no timeout was set. This commit is similar to parent commit 89dc6e0 which recently made the same change for SOCKS, for the same reason. Basically it was not well understood that when Curl_timeleft returns 0 it is not a timeout of 0 ms but actually means no timeout. Fixes https://github.com/curl/curl/issues/5177 Closes https://github.com/curl/curl/pull/5221 - socks: Fix blocking timeout logic - Document in Curl_timeleft's comment block that returning 0 signals no timeout (ie there's infinite time left). - Fix SOCKS' Curl_blockread_all for the case when no timeout was set. Prior to this change if the timeout had a value of 0 and that was passed to SOCKET_READABLE it would return right away instead of blocking. That was likely because it was not well understood that when Curl_timeleft returns 0 it is not a timeout of 0 ms but actually means no timeout. Ref: https://github.com/curl/curl/pull/5214#issuecomment-612512360 Closes https://github.com/curl/curl/pull/5220 - [Marc Hoersken brought this change] gopher: check remaining time left during write busy loop Prior to this change gopher's blocking code would block forever, ignoring any set timeout value. Assisted-by: Jay Satiro Reviewed-by: Daniel Stenberg Similar to #5220 and #5221 Closes #5214 Daniel Stenberg (13 Apr 2020) - [Dirkjan Bussink brought this change] gnutls: ensure TLS 1.3 when SRP isn't requested When SRP is requested in the priority string, GnuTLS will disable support for TLS 1.3. Before this change, curl would always add +SRP to the priority list, effectively always disabling TLS 1.3 support. With this change, +SRP is only added to the priority list when SRP authentication is also requested. This also allows updating the error handling here to not have to retry without SRP. This is because SRP is only added when requested and in that case a retry is not needed. Closes #5223 Marc Hoersken (12 Apr 2020) - tests/server: add hidden window to gracefully handle WM_CLOSE Forward Window events as signals to existing signal event handler. - tests/server: add CTRL event handler for Win32 consoles Forward CTRL events as signals to existing signal event handler. - tests/server: move all signal handling routines to util.[ch] Avoid code duplication to prepare for portability enhancements. Daniel Stenberg (12 Apr 2020) - compressed.d: stress that the headers are not modified Suggested-by: Michael Osipov Assisted-by: Jay Satiro Bug: https://github.com/curl/curl/issues/5182#issuecomment-611638008 Closes #5217 Marc Hoersken (11 Apr 2020) - tests/server/util.c: use curl_off_t instead of long for pid Avoid potential overflow of huge PIDs on Windows. Related to #5188 Assisted-by: Marcel Raad - tests: use Cygwin/msys PIDs for stunnel and sshd on Windows Since the Windows versions of both programs would write Windows PIDs to their pidfiles which we cannot handle, we need to use our known perl.exe Cygwin/msys PID together with exec() in order to tie the spawned processes to the existance of our perl.exe The perl.exe that is executing secureserver.pl and sshserver.pl has a Cygwin/msys PID, because it is started inside Cygwin/msys. Related to #5188 - tests: add Windows compatible pidwait like pidkill and pidterm Related to #5188 - tests: fix conflict between Cygwin/msys and Windows PIDs Add 65536 to Windows PIDs to allow Windows specific treatment by having disjunct ranges for Cygwin/msys and Windows PIDs.

Reminded-by: Chris Roberts Bug: https://curl.haxx.se/mail/archive-2020-04/0013.html Closes #5215 Jay Satiro (11 Apr 2020) - lib: fix conversion warnings for SOCKET_WRITABLE/READABLE - If loss of data may occur converting a timediff_t to time_t and the time value is > TIME_T_MAX then treat it as TIME_T_MAX. This is a follow-up to 8843678 which removed the (time_t) typecast from the macros so that conversion warnings could be identified. Closes https://github.com/curl/curl/pull/5199 - test1148: tolerate progress updates better (again) - Ignore intermediate progress updates. - Support locales that use a character other than period as decimal separator (eg 100,0%). test1148 checks that the progress finishes at 100% and has the right bar width. Prior to this change the test assumed that the only progress reported for such a quick transfer was 100%, however in rare instances (like in the CI where transfer time can slow considerably) there may be intermediate updates. For example, below is stderrlog1148 from a failed CI run with explicit \r and \n added (it is one line; broken up so that it's easier to understand). \r \r################################## 48.3% \r######################################################################## 100.0% \n Closes https://github.com/curl/curl/pull/5194 Marc Hoersken (10 Apr 2020) - sshserver.pl: use cached Win32 environment check variable - appveyor: partially revert 3413a110 to keep build without proxy Ref: #5211 and #4526 Reported-by: Marcel Raad - appveyor: ignore failing 'connect to non-listening proxy' tests Closes #5211 - CI/macos: convert CRLF to LF and align indentation Daniel Stenberg (9 Apr 2020) - url: allow non-HTTPS altsvc-matching for debug builds This is already partly supported but this part was missing. Reported-by: James Fuller Closes #5205 - server/resolve: remove AI_CANONNAME to make macos tell the truth With this bit set, my mac successfully resolves "ip6-localhost" when in fact there is no such host known to my machine! That in turn made test 241 wrongly execute and fail. Closes #5202 - runtests: fix warning about using an undefined variable Follow-up from 4d939ef6ceb2db1 - release-notes: fix the initial reference list output - github actions: run when pushed to master or */ci + PRs Avoid double-builds when using "local" branches for PRs. For both macos and fuzz jobs. Closes #5201 - runtests: provide nicer errormsg when protocol "dump" file is empty - [Gilles Vollant brought this change] schannel: support .P12 or .PFX client certificates Used with curl command line option like this: --cert <filename>:<password> --cert-type p12 Closes #5193 - tests: verify split initial HTTP requests with CURL_SMALLREQSEND test1294: "split request" being when the entire request isn't sent in the first go, and the remainder is sent in the PERFORM state. A GET request is otherwise not sending anything during PERFORM. test1295: same kind of split but with POST Closes #5197 - http: don't consider upload done if the request isn't completely sent off Fixes #4919 Closes #5197 - http: allow Curl_add_buffer_send() to do a short first send by force In a debug build, settting the environment variable "CURL_SMALLREQSEND" will make the first HTTP request send not send more bytes than the set amount, thus ending up verifying that the logic for handling a split HTTP request send works correctly. - connect: store connection info for QUIC connections Restores the --head functionality to the curl utility which extracts 'protocol' that is stored that way. Reported-by: James Fuller Fixes #5196 Closes #5198 - tests/README: update the port numbers list Since the pipelining server is long gone. Reported-by: James Fuller - select: remove typecast from SOCKET_WRITABLE/READABLE macros So that they don't hide conversions-by-mistake Reviewed-by: Jay Satiro Closes #5190 - CURLOPT_WRITEFUNCTION.3: add inline example and new see-also Closes #5192 - release-notes: output trailing references sorted numerically - cleanup: correct copyright year range on a few files - configure: remove use of -vec-report0 from CFLAGS with icc ... as it apparently isn't (always) supported. Reported-by: Alain Miniussi Fixes #5096 Closes #5191 - warnless: remove code block for icc that didn't work Reported-by: Alain Miniussi Fixes #5096 Marc Hoersken (6 Apr 2020) - dist: add missing setup-win32.h Follow up to d820224b8b Daniel Stenberg (6 Apr 2020) - RELEASE-NOTES: synced - scripts/release-notes.pl: add helper script for RELEASE-NOTES maintenance This script helps putting entries in the RELEASE-NOTES using a coherent style and sorting with a minimal human editing effort - as long as the first line in the commit message is good enough! There's a short howto at the top of the file. - [Dennis Felsing brought this change] configure: don't check for Security.framework when cross-compiling Since it checks for the local file, not the cross-compiled one. Closes #5189 - TODO: Option to make -Z merge lined based outputs on stdout Closes #5175 - lib: never define CURL_CA_BUNDLE with a getenv - it breaks the build (since 6de756c9b1de34b7a1) - it's not documented and not consistent across platforms - the curl tool does that getenv magic Bug: https://github.com/curl/curl/commit/6de756c#r38127030 Reported-by: Gisle Vanem Closes #5187 Marc Hoersken (5 Apr 2020) - lib670: use the same Win32 API check as all other lib tests - appveyor: use random test server ports based upon APPVEYOR_API_URL Avoid conflicts of test server ports with AppVeyor API on localhost. Closes #5034 - appveyor: sort builds by type and add two new variants Related to #5034 and #5063 - appveyor: show failed tests in log even if test is ignored And print API response with newline only if there is one - appveyor: turn disabled tests into ignored result tests Daniel Stenberg (5 Apr 2020) - KNOWN_BUGS: fixed "USE_UNIX_SOCKETS on Windows" Fixed with #5170 (commit 23a870f2fd041278) - test1566: verify --etag-compare that gets a 304 back Verifies the fix in #5183 Closes #5186 - [Kwon-Young Choi brought this change] CURLINFO_CONDITION_UNMET: return true for 304 http status code In libcurl, CURLINFO_CONDITION_UNMET is used to avoid writing to the output file if the server did not transfered a file based on time condition. In the same manner, getting a 304 HTTP response back from the server, for example after passing a custom If-Match-* header, also fulfill this condition. Fixes #5181 Closes #5183 - [Kwon-Young Choi brought this change] curl: allow both --etag-compare and --etag-save with same file name This change inverse the order of processing for the --etag-compare and --etag-save option to process first --etag-compare. This in turn allows to use the same file name to compare and save an etag. The original behavior of not failing if the etag file does not exists is conserved. Fixes #5179 Closes #5180 Viktor Szakats (4 Apr 2020) - windows: enable UnixSockets with all build toolchains Extend existing unix socket support in Windows builds to be enabled for all toolchain vendors or versions. (Previously it was only supported with certain MSVC versions + more recent Windows 10 SDKs) Ref: https://devblogs.microsoft.com/commandline/af_unix-comes-to-windows/ Ref: https://github.com/curl/curl/issues/5162 Closes: https://github.com/curl/curl/pull/5170 Daniel Stenberg (4 Apr 2020) - KNOWN_BUGS: Store TLS context per transfer instead of per connection Closes #5102 Marc Hoersken (3 Apr 2020) - sockfilt: remove redundancy in timeout handling And update other logmsg output in select_ws on Windows. - sockfilt: fix handling of ready closed sockets on Windows Replace the incomplete workaround regarding FD_CLOSE only signalling once by instead doing a pre-check with standard select and storing the result for later use. select keeps triggering on closed sockets on Windows while WSAEventSelect fires only once with data still available. By doing the pre-check we do not run in a deadlock due to waiting forever for another FD_CLOSE event. - sockfilt: fix race-condition of waiting threads and event handling Fix race-condition of waiting threads finishing while events are already being processed which lead to invalid or skipped events. Use mutex to check for one event at a time or do post-processing. In addition to mutex-based locking use specific event as signal. Closes #5156 Daniel Stenberg (2 Apr 2020) - [Leo Neat brought this change] CI-fuzz: increase fuzz time to 40 minutes Closes #5174 Marc Hoersken (2 Apr 2020) - CI: increase Azure Pipelines timeouts due to performance issues The current demand on Azure negatively impacts the CI performance. - runtests.pl: log host OS as detected by Perl environment - ftpserver.pl: log before and after data connection is closed Daniel Stenberg (1 Apr 2020) - RELEASE-NOTES: synced - RELEASE-PROCEDURE.md: run the copyright.pl script! - vquic/ngtcp2.h: update copyright year range Follow-up to 0736ee73d346a52 - [Daiki Ueno brought this change] CI: add build with ngtcp2 + gnutls on Travis CI - [Daiki Ueno brought this change] vquic: add support for GnuTLS backend of ngtcp2 Currently, the TLS backend used by vquic/ngtcp2.c is selected at compile time. Therefore OpenSSL support needs to be explicitly disabled.

A best effort revocation check ignores errors that the revocation check was unable to take place. The reasoning is described in detail below and discussed further in the PR. --- When running e.g. with Fiddler, the schannel backend fails with an unhelpful error message: Unknown error (0x80092012) - The revocation function was unable to check revocation for the certificate. Sadly, many enterprise users who are stuck behind MITM proxies suffer the very same problem. This has been discussed in plenty of issues: https://github.com/curl/curl/issues/3727, https://github.com/curl/curl/issues/264, for example. In the latter, a Microsoft Edge developer even made the case that the common behavior is to ignore issues when a certificate has no recorded distribution point for revocation lists, or when the server is offline. This is also known as "best effort" strategy and addresses the Fiddler issue. Unfortunately, this strategy was not chosen as the default for schannel (and is therefore a backend-specific behavior: OpenSSL seems to happily ignore the offline servers and missing distribution points). To maintain backward-compatibility, we therefore add a new flag (`CURLSSLOPT_REVOKE_BEST_EFFORT`) and a new option (`--ssl-revoke-best-effort`) to select the new behavior. Due to the many related issues Git for Windows and GitHub Desktop, the plan is to make this behavior the default in these software packages. The test 2070 was added to verify this behavior, adapted from 310.

The first *poll() is then expected to return early and the second not - as the first is supposed to drain the socketpair pipe. It turns out however that when given "excessive" amounts of writes to the pipe, some operating systems (the Solaris based are known) will return EAGAIN before the pipe is drained, which in our test case causes the second *poll() call to also abort early. This change attempts to avoid the OS-specific behaviors in the test by reducing the amount of wakeup calls from 1234567 to 10.

Fixes #4860 Closes #4833 Reported-by: RuurdBeerstra on github - [Patrick Monnerat brought this change] mime: do not perform more than one read in a row Input buffer filling may delay the data sending if data reads are slow. To overcome this problem, file and callback data reads do not accumulate in buffer anymore. All other data (memory data and mime framing) are considered as fast and still concatenated in buffer. As this may highly impact performance in terms of data overhead, an early end of part data check is added to spare a read call. When encoding a part's data, an encoder may require more bytes than made available by a single read. In this case, the above rule does not apply and reads are performed until the encoder is able to deliver some data. Tests 643, 644, 645, 650 and 654 have been adapted to the output data changes, with test data size reduced to avoid the boredom of long lists of 1-byte chunks in verification data. New test 667 checks mimepost using single-byte read callback with encoder. New test 668 checks the end of part data early detection. Fixes #4826 Reported-by: MrdUkk on github - [Patrick Monnerat brought this change] mime: latch last read callback status.

This is a follow-up to cf7760a from several days ago which fixed Curl_multi_wait to stop busy looping sread on the non-blocking wakeup socket if it was closed (ie sread returns 0).

As upload buffer size is significant in this kind of tests, shorten it in similar test 652. Fixes #4860 Reported-by: RuurdBeerstra on github - [Patrick Monnerat brought this change] mime: do not perform more than one read in a row Input buffer filling may delay the data sending if data reads are slow. To overcome this problem, file and callback data reads do not accumulate in buffer anymore. All other data (memory data and mime framing) are considered as fast and still concatenated in buffer. As this may highly impact performance in terms of data overhead, an early end of part data check is added to spare a read call. When encoding a part's data, an encoder may require more bytes than made available by a single read. In this case, the above rule does not apply and reads are performed until the encoder is able to deliver some data. Tests 643, 644, 645, 650 and 654 have been adapted to the output data changes, with test data size reduced to avoid the boredom of long lists of 1-byte chunks in verification data. New test 664 checks mimepost using single-byte read callback with encoder. New test 665 checks the end of part data early detection. Fixes #4826 Reported-by: MrdUkk on github - [Patrick Monnerat brought this change] mime: latch last read callback status. In case a read callback returns a status (pause, abort, eof, error) instead of a byte count, drain the bytes read so far but remember this status for further processing. Takes care of not losing data when pausing, and properly resume a paused mime structure when requested. New tests 670-673 check unpausing cases, with easy or multi interface and mime or form api.

Reported-by: Sunny Bean Fixes #4946 Closes #4947 - nit: Copyright year out of date Follow-up to 1fc0617dcc Jay Satiro (18 Feb 2020) - tool_util: Improve Windows version of tvnow() - Change tool_util.c tvnow() for Windows to match more closely to timeval.c Curl_now(). - Create a win32 init function for the tool, since some initialization is required for the tvnow() changes. Prior to this change the monotonic time function used by curl in Windows was determined at build-time and not runtime. That was a problem because when curl was built targeted for compatibility with old versions of Windows (eg _WIN32_WINNT < 0x0600) it would use GetTickCount which wraps every 49.7 days that Windows has been running. This change makes curl behave similar to libcurl's tvnow function, which determines at runtime whether the OS is Vista+ and if so calls QueryPerformanceCounter instead. (Note QueryPerformanceCounter is used because it has higher resolution than the more obvious candidate GetTickCount64). The changes to tvnow are basically a copy and paste but the types in some cases are different.

Currently, curl (with libssh2) does not take keys from your known_hosts file into account when talking to a server. With this patch the known_hosts file will be searched for an entry matching the hostname and, if found, libssh2 will be told to claim this key type from the server. Closes https://github.com/curl/curl/pull/4747 - [Nicolas Guillier brought this change] cmake: Improve libssh2 check on Windows - Add "libssh2" name to FindLibSSH2 library search. On Windows systems, libSSH2 CMake installation may name the library "LibSSH2". Prior to this change cmake only checked for name "ssh2". On Linux that works fine because it will prepend the "lib", but it doesn't do that on Windows.

CERT_NAME_SEARCH_ALL_NAMES_FLAG doesn't exist before Windows 8. As a result CertGetNameString doesn't quite work on those versions of Windows. This change provides an alternative solution for CertGetNameString by iterating through CERT_ALT_NAME_INFO for earlier versions of Windows. Prior to this change many certificates failed the hostname validation when CURLOPT_CAINFO was used in Windows 7 and earlier. Most certificates now represent multiple hostnames and rely on the alternative names field exclusively to represent their hostnames.

Also, it was called after the call to `Curl_ipvalid`, which matters in case of `CURLRES_IPV4` when called from `connect.c:bindlocal`. This caused test 1048 to fail on classic MinGW. The code ignores `conn->ip_version` as done previously in the individual resolver backends.

Some file systems allow for directory traversal; in this case that it should be possible to create child directories when permission to the parent directory is restricted. This is a regression caused by me in f16bed0 (precedes curl-7_61_1). Basically I had assumed that if a directory already existed it would fail only with error EEXIST, and not error EACCES. The latter may happen if the directory exists but has certain restricted permissions.

This is now used for the handshake, read, write, and close.

This involves keeping track of the length of data buffered into the TLS engine, and assumes that when CURLE_AGAIN is returned, the write function will be called again with the same data and length arguments. This is the same requirement of SSL_write. Handle TLS close notify as EOF when reading by returning 0.

In practice, CURL always sets the first parameter (`size`) to 1. This practice is also enshrined in documentation and cannot be changed in future. The documentation states that the default callback is `fwrite`, which means `fwrite` must be a suitable function for this purpose. However, the documentation also states that the callback must return the number of *bytes* it successfully handled, whereas ISO C `fwrite` returns the number of items (each of size `size`) which it wrote. The only way these numbers can be equal is if `size` is 1. Since `size` is 1 and can never be changed in future anyway, document that fact explicitly and let users rely on it.

Closes #4699 - conncache: CONNECT_ONLY connections assumed always in-use This makes them never to be considered "the oldest" to be discarded when reaching the connection cache limit. The reasoning here is that CONNECT_ONLY is primarily used in combination with using the connection's socket post connect and since that is used outside of curl's knowledge we must assume that it is in use until explicitly closed.

This mainly affects building with the Visual Studio project files found in the projects dir. Prior to this change the cmake and winbuild build systems already disabled 4127 globally for when building with Microsoft's compiler. Also, 4127 was already disabled for all build systems in the limited circumstance of the WHILE_FALSE macro which disabled the warning specifically for while(0). This commit removes the WHILE_FALSE macro and all other cruft in favor of disabling globally in curl_setup. Background: We have various macros that cause 0 or 1 to be evaluated, which would cause warning C4127 in Visual Studio. For example this causes it: #define Curl_resolver_asynch() 1 Full behavior is not clearly defined and inconsistent across versions. However it is documented that since VS 2015 Update 3 Microsoft has addressed this somewhat but not entirely, not warning on while(true) for example. Prior to this change some C4127 warnings occurred when I built with Visual Studio using the generated projects in the projects dir.

This is basically only a problem in single line macros, and the code which exemplified this was essentially: do { if((x) != NULL) { x = NULL; } } while(0) ..where the final parenthesis of while(0) matched the regexp, and the legal assignment in the block triggered the warning. Fix by making the regexp less greedy by matching for the tell-tale signs of the if statement ending.

Prior to this change 0ab38f5 (precedes 7.67.0) increased the sensitivity of OpenSSL's SSL_ERROR_SYSCALL error so that abrupt server closures were also considered errors. For example, a server that does not send a known protocol termination point (eg HTTP content length or chunked encoding) _and_ does not send a TLS termination point (close_notify alert) would cause an error if it closed the connection. To be clear that behavior made it into release build 7.67.0 unintentionally. Several users have reported it as an issue. Ultimately the idea is a good one, since it can help prevent against a truncation attack. Other SSL backends may already behave similarly (such as Windows native OS SSL Schannel). However much more of our user base is using OpenSSL and there is a mass of legacy users in that space, so I think that behavior should be partially reverted and then rolled out slowly. This commit changes the behavior so that the increased sensitivity is disabled in all curl builds except curl debug builds (DEBUGBUILD). If after a period of time there are no major issues then it can be enabled in dev and release builds with the newest OpenSSL (1.1.1+), since users using the newest OpenSSL are the least likely to have legacy problems.

Since we are not in control of the error code we don't know what information may be needed by the error string's format specifiers. Prior to this change Windows API error strings which contain specifiers (think specifiers like similar to printf specifiers) would not be shown. The FormatMessage Windows API call which turns a Windows error code into a string could fail and set error ERROR_INVALID_PARAMETER if that error string contained a format specifier. FormatMessage expects a va_list for the specifiers, unless inserts are ignored in which case no substitution is attempted.

Closes https://github.com/curl/curl/pull/4511 - runtests: get textaware info from curl instead of perl The MSYS system on Windows can run the test suite for curl built with any toolset. When built with the MSYS GCC, curl uses Unix line endings, while it uses Windows line endings when built with the MinGW GCC, and `^O` reports 'msys' in both cases. Use the curl executable itself to determine the line endings instead, which reports 'x86_64-pc-msys' when built with the MSYS GCC.

Previously it would keep looping. Reported-by: SumatraPeter on github Bug: #4393 Closes #4396 Jay Satiro (21 Sep 2019) - socks: Fix destination host shown on SOCKS5 error Prior to this change when a server returned a socks5 connect error then curl would parse the destination address:port from that data and show it to the user as the destination: curld -v --socks5 10.0.3.1:1080 http://google.com:99 * SOCKS5 communication to google.com:99 * SOCKS5 connect to IPv4 172.217.12.206 (locally resolved) * Can't complete SOCKS5 connection to 253.127.0.0:26673. (1) curl: (7) Can't complete SOCKS5 connection to 253.127.0.0:26673. (1) That's incorrect because the address:port included in the connect error is actually a bind address:port (typically unused) and not the destination address:port. This fix changes curl to show the destination information that curl sent to the server instead: curld -v --socks5 10.0.3.1:1080 http://google.com:99 * SOCKS5 communication to google.com:99 * SOCKS5 connect to IPv4 172.217.7.14:99 (locally resolved) * Can't complete SOCKS5 connection to 172.217.7.14:99. (1) curl: (7) Can't complete SOCKS5 connection to 172.217.7.14:99.

Reported-by: Paul Dreik Closes #4386 - [Paul Dreik brought this change] urlapi: avoid index underflow for short ipv6 hostnames If the input hostname is "[", hlen will underflow to max of size_t when it is subtracted with 2. hostname[hlen] will then cause a warning by ubsanitizer: runtime error: addition of unsigned offset to 0x<snip> overflowed to 0x<snip> I think that in practice, the generated code will work, and the output of hostname[hlen] will be the first character "[". This can be demonstrated by the following program (tested in both clang and gcc, with -O3) int main() { char* hostname=strdup("["); size_t hlen = strlen(hostname); hlen-=2; hostname++; printf("character is %d\n",+hostname[hlen]); free(hostname-1); } I found this through fuzzing, and even if it seems harmless, the proper thing is to return early with an error.
