2020-05-22Revert "sendf: make failf() use the mvsnprintf() return code"Daniel Stenberg
This reverts commit 74623551f306990e70c7c5515b88972005604a74. Instead mark the function call with (void). Getting the return code and using it instead triggered Coverity warning CID 1463596 because snprintf() can return a negative value... Closes #5441
2020-05-19sha256: move assign to the declaration lineDaniel Stenberg
Follow-up to fae30656. Should've been squashed with that commit...
2020-05-19sha256: fixed potentially uninitialized variableSiva Sivaraman
Closes #5414
2020-05-19sendf: make failf() use the mvsnprintf() return codeDaniel Stenberg
... and avoid a strlen() call. Fixes a MonocleAI warning. Reported-by: MonocleAI Fixes #5413 Closes #5420
2020-05-19hostip: make Curl_printable_address not return anythingDaniel Stenberg
It was not used much anyway and instead we let it store a blank buffer in case of failure. Reported-by: MonocleAI Fixes #5411 Closes #5418
2020-05-19ftp: mark return-ignoring calls to Curl_GetFTPResponse with (void)Daniel Stenberg
They're done on purpose, make that visible in the code. Reported-by: MonocleAI Fixes #5412 Closes #549
2020-05-17dynbuf: return NULL when there's no buffer lengthDaniel Stenberg
... as returning a "" is not a good idea as the string is supposed to be allocated and returning a const string will cause issues. Reported-by: Brian Carpenter Follow-up to ed35d6590e72c Closes #5405

Fixes #1410 Closes #5401
2020-05-15setopt: support certificate options in memory with struct curl_blobGilles Vollant
This change introduces a generic way to provide binary data in setopt options, called BLOBs. This change introduces these new setopts: CURLOPT_ISSUERCERT_BLOB, CURLOPT_PROXY_SSLCERT_BLOB, CURLOPT_PROXY_SSLKEY_BLOB, CURLOPT_SSLCERT_BLOB and CURLOPT_SSLKEY_BLOB. Reviewed-by: Daniel Stenberg Closes #5357
2020-05-15source cleanup: remove all custom typedef structsDaniel Stenberg
- Stick to a single unified way to use structs - Make checksrc complain on 'typedef struct {' - Allow them in tests, public headers and examples - Let MD4_CTX, MD5_CTX, and SHA256_CTX typedefs remain as they actually typedef different types/structs depending on build conditions. Closes #5338
2020-05-15ftp: make domore_getsock() return the secondary socket properlyDaniel Stenberg
Previously, after PASV and immediately after the data connection has connected, the function would only return the control socket to wait for which then made the data connection simply timeout and not get polled correctly. This become obvious when running test 1631 and 1632 event- based.
2020-05-15ftp: shut down the secondary connection properly when SSL is usedDaniel Stenberg
Reported-by: Neal Poole Fixes #5340 Closes #5385
2020-05-14curl_setup: support Unicode functions to open files on WindowsMarcel Raad
Use them only if `_UNICODE` is defined, in which case command-line arguments have been converted to UTF-8. Closes https://github.com/curl/curl/pull/3784
2020-05-14tool: support UTF-16 command line on WindowsMarcel Raad
- use `wmain` instead of `main` when `_UNICODE` is defined [0] - define `argv_item_t` as `wchar_t *` in this case - use the curl_multibyte gear to convert the command-line arguments to UTF-8 This makes it possible to pass parameters with characters outside of the current locale on Windows, which is required for some tests, e.g. the IDN tests. Out of the box, this currently only works with the Visual Studio project files, which default to Unicode, and winbuild with the `ENABLE_UNICODE` option. [0] https://devblogs.microsoft.com/oldnewthing/?p=40643 Ref: https://github.com/curl/curl/issues/3747 Closes https://github.com/curl/curl/pull/3784
2020-05-14curl_multibyte: add to curlxMarcel Raad
This will also be needed in the tool and tests. Ref: https://github.com/curl/curl/pull/3758#issuecomment-482197512 Closes https://github.com/curl/curl/pull/3784
2020-05-14url: make the updated credentials URL-encoded in the URLDaniel Stenberg
Found-by: Gregory Jefferis Reported-by: Jeroen Ooms Added test 1168 to verify. Bug spotted when doing a redirect. Bug: https://github.com/jeroen/curl/issues/224 Closes #5400
2020-05-14vauth/cleartext: fix theoretical integer overflowMajor_Tom
Fix theoretical integer overflow in Curl_auth_create_plain_message. The security impact of the overflow was discussed on hackerone. We agreed this is more of a theoretical vulnerability, as the integer overflow would only be triggerable on systems using 32-bits size_t with over 4GB of available memory space for the process. Closes #5391
2020-05-14checksrc: enhance the ASTERISKSPACE and update code accordinglyDaniel Stenberg
Fine: "struct hello *world" Not fine: "struct hello* world" (and variations) Closes #5386
2020-05-13OpenSSL: have CURLOPT_CRLFILE imply CURLSSLOPT_NO_PARTIALCHAINDaniel Stenberg
... to avoid an OpenSSL bug that otherwise makes the CRL check to fail. Reported-by: Michael Kaufmann Fixes #5374 Closes #5376
2020-05-13url: reject too long input when parsing credentialsDaniel Stenberg
Since input passed to libcurl with CURLOPT_USERPWD and CURLOPT_PROXYUSERPWD circumvents the regular string length check we have in Curl_setstropt(), the input length limit is enforced in Curl_parse_login_details too, separately. Reported-by: Thomas Bouzerar Closes #5383
2020-05-12easy: fix dangling pointer on easy_perform faildenzor
Closes https://github.com/curl/curl/pull/5363
2020-05-12url: sort the protocol schemes in rough popularity orderDaniel Stenberg
When looking for a protocol match among supported schemes, check the most "popular" schemes first. It has zero functionality difference and for all practical purposes a speed difference will not be measureable but it still think it makes sense to put the least likely matches last. "Popularity" based on the 2019 user survey. Closes #5377
2020-05-10CMake: add ENABLE_ALT_SVC optionPeter Wu
Tested alt-svc with quiche. While at it, add missing MultiSSL reporting (not tested).
2020-05-10CMake: add HTTP/3 support (ngtcp2+nghttp3, quiche)Peter Wu
Add three new CMake Find modules (using the curl license, but I grant others the right to apply the CMake BSD license instead). This CMake config is simpler than the autotools one because it assumes ngtcp2 and nghttp3 to be used together. Another difference is that this CMake config checks whether QUIC is actually supported by the TLS library (patched OpenSSL or boringssl) since this can be a common configuration mistake that could result in build errors later. Unlike autotools, CMake does not warn you that the features are experimental. The user is supposed to already know that and read the documentation. It requires a very special build environment anyway. Tested with ngtcp2+OpenSSL+nghttp3 and quiche+boringssl, both built from current git master. Use `LD_DEBUG=files src/curl |& grep need` to figure out which features (libldap-2.4, libssh2) to disable due to conflicts with boringssl. Closes #5359
2020-05-08checksrc: close the .checksrc file handle when done readingDaniel Stenberg
2020-05-08CURLOPT_SSL_OPTIONS: add *_NATIVE_CA to use Windows CA store (with openssl)Gilles Vollant

2020-05-08urlapi: accept :: as a valid IPv6 addressDaniel Stenberg
Text 1560 is extended to verify. Reported-by: Pavel Volgarev Fixes #5344 Closes #5351
2020-05-08*_sspi: fix bad uses of CURLE_NOT_BUILT_INPeter Wang
Return CURLE_AUTH_ERROR instead of CURLE_NOT_BUILT_IN for other instances of QuerySecurityPackageInfo failing, as in commit 2a81439553286f12cd04a4bdcdf66d8e026d8201. Closes #5355
2020-05-07ngtcp2: introduce qlog supportDaniel Stenberg
If the QLOGDIR environment variable is set, enable qlogging. ... and create Curl_qlogdir() in the new generic vquic/vquic.c file for QUIC functions that are backend independent. Closes #5353
2020-05-07ntlm_sspi: fix bad use of CURLE_NOT_BUILT_INDaniel Stenberg
That return code is reserved for build-time conditional code not being present while this was a regular run-time error from a Windows API. Reported-by: wangp on github Fixes #5349 Closes #5350
2020-05-07http2: simplify and clean up trailer handlingDaniel Stenberg
Triggered by a crash detected by OSS-Fuzz after the dynbuf introduction in ed35d6590e72. This should make the trailer handling more straight forward and hopefully less error-prone. Deliver the trailer header to the callback already at receive-time. No longer caches the trailers to get delivered at end of stream. Bug: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=22030 Closes #5348
2020-05-05libssh2: convert over to use dynbufDaniel Stenberg
In my very basic test that lists sftp://127.0.0.1/tmp/, this patched code makes 161 allocations compared to 194 in git master. A 17% reduction. Closes #5336
2020-05-05quiche: enable qlog outputDaniel Stenberg
quiche has the potential to log qlog files. To enable this, you must build quiche with the qlog feature enabled `cargo build --features qlog`. curl then passes a file descriptor to quiche, which takes ownership of the file. The FD transfer only works on UNIX. The convention is to enable logging when the QLOGDIR environment is set. This should be a path to a folder where files are written with the naming template <SCID>.qlog. Co-authored-by: Lucas Pardue Replaces #5337 Closes #5341
2020-05-04urldata.h: remove #define HEADERSIZE, not used anymoreDaniel Stenberg

2020-05-04connect: make happy eyeballs work for QUIC (again)Daniel Stenberg
Follow-up from dbd16c3e256c6c (regression in 7.70.0) Closes #5334
2020-05-04connect: add two asserts to clue code analyzers in a littleDaniel Stenberg
2020-05-04http_proxy: ported to use dynbuf instead of a static size bufferDaniel Stenberg
Removes a 16K static buffer from the easy handle. Simplifies the code.
2020-05-04dynbuf: introduce internal generic dynamic buffer functionsDaniel Stenberg
A common set of functions instead of many separate implementations for creating buffers that can grow when appending data to them. Existing functionality has been ported over. In my early basic testing, the total number of allocations seem at roughly the same amount as before, possibly a few less. See docs/DYNBUF.md for a description of the API. Closes #5300
2020-05-03asyn-*: remove support for never-used NULL entry pointersDaniel Stenberg
... and instead convert those to asserts to make sure they are truly never NULL. Closes #5324
2020-05-02asyn-thread: fix cppcheck warningJay Satiro
- Check for NULL entry parameter before attempting to deref entry in Curl_resolver_is_resolved, like is already done in asyn-ares. This is to silence cppcheck which does not seem to understand that asyn-ares and asyn-thread have separate Curl_resolver_is_resolved and those units are mutually exclusive. Prior to this change it warned of a scenario where asyn-thread's Curl_resolver_is_resolved is called with a NULL entry from asyn-ares, but that couldn't happen. Reported-by: rl1987@users.noreply.github.com Fixes https://github.com/curl/curl/issues/5326
2020-05-02select: fix overflow protection in Curl_socket_checkJay Satiro
Follow-up to a96c752 which changed the timeout_ms type from time_t to timediff_t. Ref: https://github.com/curl/curl/pull/5240 Closes https://github.com/curl/curl/pull/5286
2020-05-02libssh2: set the expected total size in SCP upload initDaniel Stenberg
... as otherwise the progress callback gets called without that information, making the progress meter have less info. Reported-by: Murugan Balraj Bug: https://curl.haxx.se/mail/archive-2020-05/0000.html Closes #5317
2020-04-30GnuTLS: Backend support for CURLINFO_SSL_VERIFYRESULTEmil Engler
Closes #5287
2020-04-30conncache: various concept cleanupsDaniel Stenberg
More connection cache accesses are protected by locks. CONNCACHE_* is a beter prefix for the connection cache lock macros. Curl_attach_connnection: now called as soon as there's a connection struct available and before the connection is added to the connection cache. Curl_disconnect: now assumes that the connection is already removed from the connection cache. Ref: #4915 Closes #5009
2020-04-29schannel: source code reindentDaniel Stenberg
White space edits only. Conform better to standard curl source code indenting style. Closes #5305
