2020-06-15http: move header storage to Curl_easy from connectdataDaniel Stenberg
Since the connection can be used by many independent requests (using HTTP/2 or HTTP/3), things like user-agent and other transfer-specific data MUST NOT be kept connection oriented as it could lead to requests getting the wrong string for their requests. This struct data was lingering like this due to old HTTP1 legacy thinking where it didn't mattered.. Fixes #5566 Closes #5567
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
2019-12-09conn: always set bits.close with connclose()Daniel Stenberg
Closes #4690
2019-10-02chunked-encoding: stop hiding the CURLE_BAD_CONTENT_ENCODING errorDaniel Stenberg
Unknown content-encoding would get returned as CURLE_WRITE_ERROR if the response is chunked-encoded. Reported-by: Ilya Kosarev Fixes #4310 Closes #4449
2019-09-20http_proxy: part of conditional expression is always true: !errorDaniel Stenberg
Fixes warning detected by PVS-Studio Fixes #4374
2019-06-02NTLM: reset proxy "multipass" state when CONNECT request is doneSergey Ogryzkov
Closes #3972
2019-01-11urldata: rename easy_conn to just connDaniel Stenberg
We use "conn" everywhere to be a pointer to the connection. Introduces two functions that "attaches" and "detaches" the connection to and from the transfer. Going forward, we should favour using "data->conn" (since a transfer always only has a single connection or none at all) to "conn->data" (since a connection can have none, one or many transfers associated with it and updating conn->data to be correct is error prone and a frequent reason for internal issues). Closes #3442
2018-09-16http: made Curl_add_buffer functions take a pointer-pointerDaniel Stenberg
... so that they can clear the original pointer on failure, which makes the error-paths and their cleanups easier. Closes #2992
2018-08-09http_proxy: Remove unused macro SELECT_TIMEOUTRikard Falkeborn
Usage was removed in 5113ad0424044458ac497fa1458ebe0101356b22. Closes #2852
2018-06-12Curl_debug: remove dead printhost codeDaniel Stenberg
The struct field is never set (since 5e0d9aea3) so remove the use of it and remove the connectdata pointer from the prototype. Reported-by: Tejas Bug: https://curl.haxx.se/mail/lib-2018-06/0054.html Closes #2647
2018-06-11cppcheck: fix warningsMarian Klymov
- Get rid of variable that was generating false positive warning (unitialized) - Fix issues in tests - Reduce scope of several variables all over etc Closes #2631
2018-05-31strictness: correct {infof, failf} format specifiersRikard Falkeborn
Closes #2623

2018-03-11HTTP: allow "header;" to replace an internal header with a blank oneDaniel Stenberg
Reported-by: Michael Kaufmann Fixes #2357 Closes #2362
2017-12-07CONNECT: keep close connection flag in http_connect_state structZachary Seguin
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
