Fixes #2088 Closes #2157
2017-10-29timeleft: made two more users of Curl_timeleft use timediff_tDaniel Stenberg
2017-09-11code style: use spaces around equals signsDaniel Stenberg
2017-09-07http-proxy: when not doing CONNECT, that phase is done immediatelyDaniel Stenberg
`conn->connect_state` is NULL when doing a regular non-CONNECT request over the proxy and should therefor be considered complete at once. Fixes #1853 Closes #1862 Reported-by: Lawrence Wagerfield
2017-09-05http-proxy: treat all 2xx as CONNECT successDaniel Stenberg
Added test 1904 to verify. Reported-by: Lawrence Wagerfield Fixes #1859 Closes #1860
2017-08-16http_proxy: fix build error for CURL_DOES_CONVERSIONSMaksim Stsepanenka
Closes https://github.com/curl/curl/pull/1793
2017-08-14strtoofft: reduce integer overflow risks globallyDaniel Stenberg
... make sure we bail out on overflows. Reported-by: Brian Carpenter Closes #1758
2017-06-18http_proxy: fix build with http and proxyMarcel Raad
After deff7de0eb0e22d2d142b96b9cc84cd8db5d2a48, the build without CURL_DISABLE_PROXY and CURL_DISABLE_HTTP was failing because of missing includes.
2017-06-18http_proxy: fix compiler warningMarcel Raad
With CURL_DISABLE_PROXY or CURL_DISABLE_HTTP, GCC complained about a missing prototype for Curl_connect_free.
2017-06-16http-proxy: fix chunked-encoded CONNECT responsesDaniel Stenberg
Regression since 5113ad0424. ... and remove 'flaky' from test 1061 again Closes #1579
2017-06-16http-proxy: deal with EAGAINDaniel Stenberg
... the previous code would reset the header length wrongly (since 5113ad0424). This makes test 1060 reliable again. Also: make sws send even smaller chunks of data to increase the likeliness of this happening.
2017-06-16http-proxy: fix build with --disable-proxy or --disable-httpDaniel Stenberg
Reported-by: Dan Fandrich
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
2017-05-01http-proxy: use a dedicated CONNECT response bufferDaniel Stenberg
To make it suitably independent of the receive buffer and its flexible size.
2017-04-26http-proxy: remove unused argument from Curl_proxyCONNECT()Daniel Stenberg
2017-03-13Improve code readbilitySylvestre Ledru
... by removing the else branch after a return, break or continue. Closes #1310
2017-03-12url: add option CURLOPT_SUPPRESS_CONNECT_HEADERSDesmond O. Chang
- Add new option CURLOPT_SUPPRESS_CONNECT_HEADERS to allow suppressing proxy CONNECT response headers from the user callback functions CURLOPT_HEADERFUNCTION and CURLOPT_WRITEFUNCTION. - Add new tool option --suppress-connect-headers to expose CURLOPT_SUPPRESS_CONNECT_HEADERS and allow suppressing proxy CONNECT response headers from --dump-header and --include. Assisted-by: Jay Satiro Assisted-by: CarloCannas@users.noreply.github.com Closes https://github.com/curl/curl/pull/783
2017-03-11http_proxy: Ignore TE and CL in CONNECT 2xx responsesJay Satiro
A client MUST ignore any Content-Length or Transfer-Encoding header fields received in a successful response to CONNECT. "Successful" described as: 2xx (Successful). RFC 7231 4.3.6 Prior to this change such a case would cause an error. In some ways this bug appears to be a regression since c50b878. Prior to that libcurl may have appeared to function correctly in such cases by acting on those headers instead of causing an error. But that behavior was also incorrect. Bug: https://github.com/curl/curl/issues/1317 Reported-by: mkzero@users.noreply.github.com
2017-02-18proxy: fix hostname resolution and IDN conversionMichael Kaufmann
Properly resolve, convert and log the proxy host names. Support the "--connect-to" feature for SOCKS proxies and for passive FTP data transfers. Follow-up to cb4e2be Reported-by: Jay Satiro Fixes https://github.com/curl/curl/issues/1248
2017-02-09http_proxy: avoid freeing static memoryDaniel Stenberg
Follow up to 7fe81ec298e0: make sure 'host' is either NULL or malloced.
2017-02-09http_proxy: Fix tiny memory leak upon edge case connecting to proxyCameron MacMinn
Fixes #1255
2016-12-19http_proxy: Fix proxy CONNECT hang on pending dataJay Satiro
- Check for pending data before waiting on the socket. Bug: https://github.com/curl/curl/issues/1156 Reported-by: Adam Langley
2016-12-13checksrc: stricter no-space-before-paren enforcementDaniel Stenberg
In order to make the code style more uniform everywhere
2016-12-01http_proxy: simplify CONNECT response readingDaniel Stenberg
Since it now reads responses one byte a time, a loop could be removed and it is no longer limited to get the whole response within 16K, it is now instead only limited to 16K maximum header line lengths.
2016-12-01CONNECT: read responses one byte at a timeDaniel Stenberg
... so that it doesn't read data that is actually coming from the remote. 2xx responses have no body from the proxy, that data is from the peer. Fixes #1132
2016-12-01CONNECT: reject TE or CL in 2xx responsesDaniel Stenberg
A server MUST NOT send any Transfer-Encoding or Content-Length header fields in a 2xx (Successful) response to CONNECT. (RFC 7231 section 4.3.6) Also fixes the three test cases that did this.
2016-11-24HTTPS-proxy: fixed mbedtls and polishingOkhin Vasilij
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.
2016-11-18lib: fix compiler warnings after de4de4e3c7cMarcel Raad
Visual C++ now complains about implicitly casting time_t (64-bit) to long (32-bit). Fix this by changing some variables from long to time_t, or explicitly casting to long where the public interface would be affected. Closes #1131
2016-10-31strcasecompare: all case insensitive string compares ignore locale nowDaniel Stenberg
We had some confusions on when each function was used. We should not act differently on different locales anyway.
2016-10-18select: switch to macros in uppercaseDaniel Stenberg
Curl_select_ready() was the former API that was replaced with Curl_select_check() a while back and the former arg setup was provided with a define (in order to leave existing code unmodified). Now we instead offer SOCKET_READABLE and SOCKET_WRITABLE for the most common shortcuts where only one socket is checked. They're also more visibly macros.
2016-08-28http2: make sure stream errors don't needlessly close the connectionDaniel Stenberg
With HTTP/2 each transfer is made in an indivial logical stream over the connection, making most previous errors that caused the connection to get forced-closed now instead just kill the stream and not the connection. Fixes #941
2016-08-16Revert "Proxy-Connection: stop sending this header by default"Daniel Stenberg
This reverts commit 113f04e664b16b944e64498a73a4dab990fe9a68.
2016-06-22internals: rename the SessionHandle struct to Curl_easyDaniel Stenberg
2016-04-29lib: include curl_printf.h as one of the last headersDaniel Stenberg
curl_printf.h defines printf to curl_mprintf, etc. This can cause problems with external headers which may use __attribute__((format(printf, ...))) markers etc. To avoid that they cause problems with system includes, we include curl_printf.h after any system headers. That makes the three last headers to always be, and we keep them in this order: curl_printf.h curl_memory.h memdebug.h None of them include system headers, they all do funny #defines. Reported-by: David Benjamin Fixes #743
2016-04-17news: CURLOPT_CONNECT_TO and --connect-toMichael Kaufmann
Makes curl connect to the given host+port instead of the host+port found in the URL.
2016-02-08Proxy-Connection: stop sending this header by defaultDaniel Stenberg
RFC 7230 says we should stop. Firefox already stopped. Bug: https://github.com/curl/curl/issues/633 Reported-By: Brad Fitzpatrick Closes #633
2016-02-03URLs: change all http:// URLs to https://Daniel Stenberg
2015-06-17FTP: do the HTTP CONNECT for data connection blockingDaniel Stenberg
** WORK-AROUND ** The introduced non-blocking general behaviour for Curl_proxyCONNECT() didn't work for the data connection establishment unless it was very fast. The newly introduced function argument makes it operate in a more blocking manner, more like it used to work in the past. This blocking approach is only used when the FTP data connecting through HTTP proxy. Blocking like this is bad. A better fix would make it work more asynchronously. Bug: https://github.com/bagder/curl/issues/278
2015-05-18http2: separate multiplex/pipelining + cleanup memory leaksDaniel Stenberg
2015-05-08proxy: add newline to info messageDaniel Stenberg
2015-03-16free: instead of Curl_safefree()Daniel Stenberg
Since we just started make use of free(NULL) in order to simplify code, this change takes it a step further and: - converts lots of Curl_safefree() calls to good old free() - makes Curl_safefree() not check the pointer before free() The (new) rule of thumb is: if you really want a function call that frees a pointer and then assigns it to NULL, then use Curl_safefree(). But we will prefer just using free() from now on.
2015-03-16Bug #149: Deletion of unnecessary checks before calls of the function "free"Markus Elfring
The function "free" is documented in the way that no action shall occur for a passed null pointer. It is therefore not needed that a function caller repeats a corresponding check. http://stackoverflow.com/questions/18775608/free-a-null-pointer-anyway-or-check-first This issue was fixed by using the software Coccinelle 1.0.0-rc24.

2015-03-07multi: fix *getsock() with CONNECTDaniel Stenberg
The code used some happy eyeballs logic even _after_ CONNECT has been sent to a proxy, while the happy eyeball phase is already (should be) over by then. This is solved by splitting the multi state into two separate states introducing the new SENDPROTOCONNECT state. Bug: http://curl.haxx.se/mail/lib-2015-01/0170.html Reported-by: Peter Laser
2015-03-03mprintf.h: remove #ifdef CURLDEBUGDaniel Stenberg
... and as a consequence, introduce curl_printf.h with that re-define magic instead and make all libcurl code use that instead.
2014-10-24code cleanup: we prefer 'CURLcode result'Daniel Stenberg
... for the local variable name in functions holding the return code. Using the same name universally makes code easier to read and follow. Also, unify code for checking for CURLcode errors with: if(result) or if(!result) instead of if(result == CURLE_OK), if(CURLE_OK == result) or if(result != CURLE_OK)
2014-10-24Curl_proxyCONNECT: remove superfluous statementDaniel Stenberg
The variable is already assigned, skip the duplicate assignment. Pointed out by cppcheck.
2014-08-25CONNECT: close proxy connections that fail to CONNECTDaniel Stenberg
This is usually due to failed auth. There's no point in us keeping such a connection alive since it shouldn't be re-used anyway. Bug: http://curl.haxx.se/bug/view.cgi?id=1381 Reported-by: Marcel Raad
2014-07-22CONNECT: Revert Curl_proxyCONNECT back to 7.29.0 designDaniel Stenberg
This reverts commit cb3e6dfa3511 and instead fixes the problem differently. The reverted commit addressed a test failure in test 1021 by simplifying and generalizing the code flow in a way that damaged the performance. Now we modify the flow so that Curl_proxyCONNECT() again does as much as possible in one go, yet still do test 1021 with and without valgrind. It failed due to mistakes in the multi state machine. Bug: http://curl.haxx.se/bug/view.cgi?id=1397 Reported-by: Paul Saab
2014-05-22bits.close: introduce connection close trackingDaniel Stenberg
Make all code use connclose() and connkeep() when changing the "close state" for a connection. These two macros take a string argument with an explanation, and debug builds of curl will include that in the debug output. Helps tracking connection re-use/close issues.
