* build: Disable Visual Studio warning "conditional expression is constant"Jay Satiro2019-12-012-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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
* ngtcp2: fix thread-safety bug in error-handlingDavid Benjamin2019-11-281-2/+3
| | | | | | | | 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

* quiche: reject headers in the wrong orderDaniel Stenberg2019-11-121-1/+6
| | | | | | | | Pseudo header MUST come before regular headers or cause an error. Reported-by: Cynthia Coan Fixes #4571 Closes #4584
* HTTP3: fix invalid use of sendto for connected UDP socketJavier Blazquez2019-10-281-4/+2
| | | | | | | | | | 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
* HTTP3: fix Windows buildJavier Blazquez2019-10-282-9/+9
| | | | | | | | | | | | | 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

* Curl_addr2string: take an addrlen argument tooDaniel Stenberg2019-08-311-2/+1
| | | | | | | | | | | 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

* quiche: register debug callback once and earlierAlessandro Ghedini2019-08-171-12/+18
| | | | | | | | | | | The quiche debug callback is global and can only be initialized once, so make sure we don't do it multiple times (e.g. if multiple requests are executed). In addition this initializes the callback before the connection is created, so we get logs for the handshake as well. Closes #4236
