2018-04-09lib: silence null-dereference warningsMarcel Raad
In debug mode, MingGW-w64's GCC 7.3 issues null-dereference warnings when dereferencing pointers after DEBUGASSERT-ing that they are not NULL. Fix this by removing the DEBUGASSERTs. Suggested-by: Daniel Stenberg Ref: https://github.com/curl/curl/pull/2463
2018-04-02cookies: when reading from a file, only remove_expired onceLauri Kasanen

Reported-by: Michael Kaufmann Fixes #2357 Closes #2362
2018-02-16http: fix the max header length detection logicDaniel Stenberg
Previously, it would only check for max length if the existing alloc buffer was to small to fit it, which often would make the header still get used. Reported-by: Guido Berhoerster Bug: https://curl.haxx.se/mail/lib-2018-02/0056.html Closes #2315

They're now wrong. Reported-by: Michael Kaufmann Closes #2277
2018-01-22http: prevent custom Authorization headers in redirectsDaniel Stenberg
... unless CURLOPT_UNRESTRICTED_AUTH is set to allow them. This matches how curl already handles Authorization headers created internally. Note: this changes behavior slightly, for the sake of reducing mistakes. Added test 317 and 318 to verify. Reported-by: Craig de Stigter Bug: https://curl.haxx.se/docs/adv_2018-b3bf.html
2018-01-13HTTP: bail out on negative Content-Length: valuesDaniel Stenberg

2017-08-18http: Don't wait on CONNECT when there is no proxyJan Alexander Steffens (heftig)
Since curl 7.55.0, NetworkManager almost always failed its connectivity check by timeout. I bisected this to 5113ad04 (http-proxy: do the HTTP CONNECT process entirely non-blocking). This patch replaces !Curl_connect_complete with Curl_connect_ongoing, which returns false if the CONNECT state was left uninitialized and lets the connection continue. Closes #1803 Fixes #1804 Also-fixed-by: Gergely Nagy

2017-06-30handler: refactor connection checkingMax Dymond
Add a new type of callback to Curl_handler which performs checks on the connection. Alter RTSP so that it uses this callback to do its own check on connection health.
2017-06-21--request-target: instead of --strip-path-slashDaniel Stenberg
... and CURLOPT_REQUEST_TARGET instead of CURLOPT_STRIP_PATH_SLASH. This option instead provides the full "alternative" target to use in the request, instead of extracting the path from the URL. Test 1298 and 1299 updated accordingly. Idea-by: Evert Pot Suggestion: https://daniel.haxx.se/blog/2017/06/19/options-with-curl/comment-page-1/#comment-18373 Closes #1593
2017-06-19http: add --strip-path-slash and CURLOPT_STRIP_PATH_SLASHDaniel Stenberg
... to enable sending "OPTIONS *" which wasn't possible previously. This option currently only works for HTTP. Added test cases 1298 + 1299 to verify Fixes #1280 Closes #1462
2017-06-14http-proxy: do the HTTP CONNECT process entirely non-blockingDaniel Stenberg
Mentioned as a problem since 2007 (8f87c15bdac63) and of course it existed even before that. Closes #1547
2017-05-30transfer: init the infilesize from the postfields...Daniel Stenberg
... with a strlen() if no size was set, and do this in the pretransfer function so that the info is set early. Otherwise, the default strlen() done on the POSTFIELDS data never sets state.infilesize. Reported-by: Vincas Razma Bug: #1294
2017-05-10multi: use a fixed array of timers instead of mallocDaniel Stenberg
... since the total amount is low this is faster, easier and reduces memory overhead. Also, Curl_expire_done() can now mark an expire timeout as done so that it never times out. Closes #1472
2017-05-01buffer: use data->set.buffer_size instead of BUFSIZEDaniel Stenberg

Don't clobber the receive buffer.
2017-03-28http: do not treat FTPS over CONNECT as HTTPSKamil Dudka
If we use FTPS over CONNECT, the TLS handshake for the FTPS control connection needs to be initiated in the SENDPROTOCONNECT state, not the WAITPROXYCONNECT state. Otherwise, if the TLS handshake completed without blocking, the information about the completed TLS handshake would be saved to a wrong flag. Consequently, the TLS handshake would be initiated in the SENDPROTOCONNECT state once again on the same connection, resulting in a failure of the TLS handshake. I was able to observe the failure with the NSS backend if curl ran through valgrind. Note that this commit partially reverts curl-7_21_6-52-ge34131d.
2017-03-28http: Fix proxy connection reuse with basic-authIsaac Boukris
When using basic-auth, connections and proxy connections can be re-used with different Authorization headers since it does not authenticate the connection (like NTLM does). For instance, the below command should re-use the proxy connection, but it currently doesn't: curl -v -U alice:a -x http://localhost:8181 http://localhost/ --next -U bob:b -x http://localhost:8181 http://localhost/ This is a regression since refactoring of ConnectionExists() as part of: cb4e2be7c6d42ca0780f8e0a747cecf9ba45f151 Fix the above by removing the username and password compare when re-using proxy connection at proxy_info_matches(). However, this fix brings back another bug would make curl to re-print the old proxy-authorization header of previous proxy basic-auth connection because it wasn't cleared. For instance, in the below command the second request should fail if the proxy requires authentication, but would succeed after the above fix (and before aforementioned commit): curl -v -U alice:a -x http://localhost:8181 http://localhost/ --next -x http://localhost:8181 http://localhost/ Fix this by clearing conn->allocptr.proxyuserpwd after use unconditionally, same as we do for conn->allocptr.userpwd. Also fix test 540 to not expect digest auth header to be resent when connection is reused. Signed-off-by: Isaac Boukris <iboukris@gmail.com> Closes https://github.com/curl/curl/pull/1350

2017-03-11authneg: clear auth.multi flag at http_doneIsaac Boukris
This flag is meant for the current request based on authentication state, once the request is done we can clear the flag. Also change auth.multi to auth.multipass for better readability.

2017-03-07http2: Fix assertion error on redirect with CL=0Tatsuhiro Tsujikawa
This fixes assertion error which occurs when redirect is done with 0 length body via HTTP/2, and the easy handle is reused, but new connection is established due to hostname change: curl: http2.c:1572: ssize_t http2_recv(struct connectdata *, int, char *, size_t, CURLcode *): Assertion `httpc->drain_total >= data->state.drain' failed. To fix this bug, ensure that http2_handle_stream is called. Fixes #1286 Closes #1302
2017-02-17http: fix missing 'Content-Length: 0' while negotiating authIsaac Boukris
- While negotiating auth during PUT/POST if a user-specified Content-Length header is set send 'Content-Length: 0'. This is what we do already in HTTPREQ_POST_FORM and what we did in the HTTPREQ_POST case (regression since afd288b). Prior to this change no Content-Length header would be sent in such a case. Bug: https://curl.haxx.se/mail/lib-2017-02/0006.html Reported-by: Dominik Hölzl Closes https://github.com/curl/curl/pull/1242
2017-01-19CURLOPT_BUFFERSIZE: support enlarging receive bufferRichy Kim
Replace use of fixed macro BUFSIZE to define the size of the receive buffer. Reappropriate CURLOPT_BUFFERSIZE to include enlarging receive buffer size. Upon setting, resize buffer if larger than the current default size up to a MAX_BUFSIZE (512KB). This can benefit protocols like SFTP. Closes #1222

2016-11-24proxy: Support HTTPS proxy and SOCKS+HTTP(s)Alex Rousskov
* HTTPS proxies: An HTTPS proxy receives all transactions over an SSL/TLS connection. Once a secure connection with the proxy is established, the user agent uses the proxy as usual, including sending CONNECT requests to instruct the proxy to establish a [usually secure] TCP tunnel with an origin server. HTTPS proxies protect nearly all aspects of user-proxy communications as opposed to HTTP proxies that receive all requests (including CONNECT requests) in vulnerable clear text. With HTTPS proxies, it is possible to have two concurrent _nested_ SSL/TLS sessions: the "outer" one between the user agent and the proxy and the "inner" one between the user agent and the origin server (through the proxy). This change adds supports for such nested sessions as well. A secure connection with a proxy requires its own set of the usual SSL options (their actual descriptions differ and need polishing, see TODO): --proxy-cacert FILE CA certificate to verify peer against --proxy-capath DIR CA directory to verify peer against --proxy-cert CERT[:PASSWD] Client certificate file and password --proxy-cert-type TYPE Certificate file type (DER/PEM/ENG) --proxy-ciphers LIST SSL ciphers to use --proxy-crlfile FILE Get a CRL list in PEM format from the file --proxy-insecure Allow connections to proxies with bad certs --proxy-key KEY Private key file name --proxy-key-type TYPE Private key file type (DER/PEM/ENG) --proxy-pass PASS Pass phrase for the private key --proxy-ssl-allow-beast Allow security flaw to improve interop --proxy-sslv2 Use SSLv2 --proxy-sslv3 Use SSLv3 --proxy-tlsv1 Use TLSv1 --proxy-tlsuser USER TLS username --proxy-tlspassword STRING TLS password --proxy-tlsauthtype STRING TLS authentication type (default SRP) All --proxy-foo options are independent from their --foo counterparts, except --proxy-crlfile which defaults to --crlfile and --proxy-capath which defaults to --capath. Curl now also supports %{proxy_ssl_verify_result} --write-out variable, similar to the existing %{ssl_verify_result} variable. Supported backends: OpenSSL, GnuTLS, and NSS. * A SOCKS proxy + HTTP/HTTPS proxy combination: If both --socks* and --proxy options are given, Curl first connects to the SOCKS proxy and then connects (through SOCKS) to the HTTP or HTTPS proxy. TODO: Update documentation for the new APIs and --proxy-* options. Look for "Added in 7.XXX" marks.
