2020-06-08quiche: update SSLKEYLOGFILE supportAlessandro Ghedini
quiche now requires the application to explicitly set the keylog path for each connection, rather than reading the environment variable itself. Closes #5541
2020-06-08ngtcp2: update with recent API changesDaniel Stenberg
Syncs with ngtcp2 commit 7e9a917d386d98 merged June 7 2020. Assisted-by: Tatsuhiro Tsujikawa Closes #5538
2020-06-04quiche: advertise draft 28 supportPeter Wu
Fix the verbose message while at it, quiche currently supports draft 27 and draft 28 simultaneously. Closes #5518
2020-06-02urldata: let the HTTP method be in the set.* structDaniel Stenberg
When the method is updated inside libcurl we must still not change the method as set by the user as then repeated transfers with that same handle might not execute the same operation anymore! This fixes the libcurl part of #5462 Test 1633 added to verify. Closes #5499
2020-05-27ngtcp2: use common key log routine for better thread-safetyPeter Wu
Tested with ngtcp2 built against the OpenSSL library. Additionally tested with MultiSSL (NSS for TLS and ngtcp2+OpenSSL for QUIC). The TLS backend (independent of QUIC) may or may not already have opened the keylog file before. Therefore Curl_tls_keylog_open is always called to ensure the file is open.
2020-05-26ngtcp2: cleanup memory when failing to connectDaniel Stenberg
Reported-by: Peter Wu Fixes #5447 (the ngtcp2 side of it) Closes #5451
2020-05-26quiche: clean up memory properly when failing to connectDaniel Stenberg
Addresses the quiche side of #5447 Reported-by: Peter Wu Closes #5450
2020-05-25ngtcp2: fix build with current ngtcp2 master implementing draft 28Peter Wu
Based on client.cc changes from ngtcp2. Tested with current git master, ngtcp2 commit c77d5731ce92, nghttp3 commit 65ff479d4380. Fixes #5444 Closes #5443
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
2020-05-05quiche: 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
2020-05-04ngtcp2: convert to dynbufDaniel Stenberg
Closes #5335

2020-03-31vquic: add support for GnuTLS backend of ngtcp2Daiki Ueno
Currently, the TLS backend used by vquic/ngtcp2.c is selected at compile time. Therefore OpenSSL support needs to be explicitly disabled. Signed-off-by: Daiki Ueno <dueno@redhat.com> Closes #5148
2020-03-30ngtcp2: update to git master for the key installation API changeDaiki Ueno
This updates the ngtcp2 OpenSSL backend to follow the API change in commit 32e703164 of ngtcp2. Notable changes are: - ngtcp2_crypto_derive_and_install_{rx,tx}_key have been added to replace ngtcp2_crypto_derive_and_install_key - the 'side' argument of ngtcp2_crypto_derive_and_install_initial_key has been removed Fixes #5166 Closes #5168
2020-03-07version: make curl_version* thread-safe without using global contextDaniel Stenberg
Closes #5010

2020-01-11ngtcp2: Add an error code for QUIC connection errorsEmil Engler
- Add new error code CURLE_QUIC_CONNECT_ERROR for QUIC connection errors. Prior to this change CURLE_FAILED_INIT was used, but that was not correct. Closes https://github.com/curl/curl/pull/4754
2019-12-20ngtcp2: Support the latest update key callback typeJay Satiro
- Remove our cb_update_key in favor of ngtcp2's new ngtcp2_crypto_update_key_cb which does the same thing. Several days ago the ngtcp2_update_key callback function prototype was changed in ngtcp2/ngtcp2@42ce09c. Though it would be possible to fix up our cb_update_key for that change they also added ngtcp2_crypto_update_key_cb which does the same thing so we'll use that instead. Ref: https://github.com/ngtcp2/ngtcp2/commit/42ce09c Closes https://github.com/curl/curl/pull/4735
2019-12-01build: Disable Visual Studio warning "conditional expression is constant"Jay Satiro
- Disable warning C4127 "conditional expression is constant" globally in curl_setup.h for when building with Microsoft's compiler. 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. Closes https://github.com/curl/curl/pull/4658
2019-11-28ngtcp2: fix thread-safety bug in error-handlingDavid Benjamin
ERR_error_string(NULL) should never be called. It places the error in a global buffer, which is not thread-safe. Use ERR_error_string_n with a local buffer instead. Closes #4645

2019-10-28HTTP3: fix invalid use of sendto for connected UDP socketJavier Blazquez
On macOS/BSD, trying to call sendto on a connected UDP socket fails with a EISCONN error. Because the singleipconnect has already called connect on the socket when we're trying to use it for QUIC transfers we need to use plain send instead. Fixes #4529 Closes https://github.com/curl/curl/pull/4533
2019-10-28HTTP3: fix Windows buildJavier Blazquez
The ngtcp2 QUIC backend was using the MSG_DONTWAIT flag for send/recv in order to perform nonblocking operations. On Windows this flag does not exist. Instead, the socket must be set to nonblocking mode via ioctlsocket. This change sets the nonblocking flag on UDP sockets used for QUIC on all platforms so the use of MSG_DONTWAIT is not needed. Fixes #4531 Closes #4532

2019-08-31Curl_addr2string: take an addrlen argument tooDaniel Stenberg
This allows the function to figure out if a unix domain socket has a file name or not associated with it! When a socket is created with socketpair(), as done in the fuzzer testing, the path struct member is uninitialized and must not be accessed. Bug: https://crbug.com/oss-fuzz/16699 Closes #4283
