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.
2016-11-22url: Fix conn reuse for local ports and interfacesJay Satiro
- Fix connection reuse for when the proposed new conn 'needle' has a specified local port but does not have a specified device interface. Bug: https://curl.haxx.se/mail/lib-2016-11/0137.html Reported-by: bjt3[at]hotmail.com
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
2016-11-17Don't mix unix domain sockets with regular onesIsaac Boukris
When reusing a connection, make sure the unix domain socket option matches.
2016-11-11URL-parser: for file://[host]/ URLs, the [host] must be localhostDaniel Stenberg
Previously, the [host] part was just ignored which made libcurl accept strange URLs misleading users. like "file://etc/passwd" which might've looked like it refers to "/etc/passwd" but is just "/passwd" since the "etc" is an ignored host name. Reported-by: Mike Crowe Assisted-by: Kamil Dudka
2016-11-05easy: Initialize info variables on easy init and duphandleJay Satiro
- Call Curl_initinfo on init and duphandle. Prior to this change the statistical and informational variables were simply zeroed by calloc on easy init and duphandle. While zero is the correct default value for almost all info variables, there is one where it isn't (filetime initializes to -1). Bug: https://github.com/curl/curl/issues/1103 Reported-by: Neal Poole
2016-10-31url: remove unconditional idn2.h includeDaniel Stenberg
Mistake brought by 9c91ec778104a
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.
2016-10-31strcasecompare: is the new name for strequal()Daniel Stenberg
... to make it less likely that we forget that the function actually does case insentive compares. Also replaced several invokes of the function with a plain strcmp when case sensitivity is not an issue (like comparing with "-").
2016-10-31connectionexists: use case sensitive user/password comparisonsDaniel Stenberg
CVE-2016-8616 Bug: https://curl.haxx.se/docs/adv_20161102B.html Reported-by: Cure53
2016-10-31escape: avoid using curl_easy_unescape() internallyDaniel Stenberg
Since the internal Curl_urldecode() function has a better API.

2016-10-31urlparse: accept '#' as end of host nameDaniel Stenberg
'http://example.com#@127.0.0.1/x.txt' equals a request to example.com for the '/' document with the rest of the URL being a fragment. CVE-2016-8624 Bug: https://curl.haxx.se/docs/adv_20161102J.html Reported-by: Fernando Muñoz
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.
2016-10-17url: skip to-be-closed connections when pipelining (follow-up)Jay Satiro
- Change back behavior so that pipelining is considered possible for connections that have not yet reached the protocol level. This is a follow-up to e5f0b1a which had changed the behavior of checking if pipelining is possible to ignore connections that had 'bits.close' set. Connections that have not yet reached the protocol level also have that bit set, and we need to consider pipelining possible on those connections.
2016-10-14url: skip to-be-closed connections when pipeliningRider Linden
No longer attempt to use "doomed" to-be-closed connections when pipelining. Prior to this change connections marked for deletion (e.g. timeout) would be erroneously used, resulting in sporadic crashes. As originally reported and fixed by Carlo Wood (origin unknown). Bug: https://github.com/curl/curl/issues/627 Reported-by: Rider Linden Closes https://github.com/curl/curl/pull/1075 Participation-by: nopjmp@users.noreply.github.com
2016-09-22New libcurl option to keep sending on errorMichael Kaufmann
Add the new option CURLOPT_KEEP_SENDING_ON_ERROR to control whether sending the request body shall be completed when the server responds early with an error status code. This is suitable for manual NTLM authentication. Reviewed-by: Jay Satiro Closes https://github.com/curl/curl/pull/904
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
2016-08-15proxy: polished the error message for unsupported schemesDaniel Stenberg
Follow up to a96319ebb93
2016-08-15proxy: reject attempts to use unsupported proxy schemesDaniel Stenberg
I discovered some people have been using "https://example.com" style strings as proxy and it "works" (curl doesn't complain) because curl ignores unknown schemes and then assumes plain HTTP instead. I think this misleads users into believing curl uses HTTPS to proxies when it doesn't. Now curl rejects proxy strings using unsupported schemes instead of just ignoring and defaulting to HTTP.
2016-08-05CURLOPT_TCP_NODELAY: now enabled by defaultDaniel Stenberg
After a few wasted hours hunting down the reason for slowness during a TLS handshake that turned out to be because of TCP_NODELAY not being set, I think we have enough motivation to toggle the default for this option. We now enable TCP_NODELAY by default and allow applications to switch it off. This also makes --tcp-nodelay unnecessary, but --no-tcp-nodelay can be used to disable it. Thanks-to: Tim Rühsen Bug: https://curl.haxx.se/mail/lib-2016-06/0143.html
2016-08-04multi: make Curl_expire() work with 0 ms timeoutsDaniel Stenberg
Previously, passing a timeout of zero to Curl_expire() was a magic code for clearing all timeouts for the handle. That is now instead made with the new Curl_expire_clear() function and thus a 0 timeout is fine to set and will trigger a timeout ASAP. This will help removing short delays, in particular notable when doing HTTP/2.
2016-08-03TLS: switch off SSL session id when client cert is usedDaniel Stenberg
CVE-2016-5419 Bug: https://curl.haxx.se/docs/adv_20160803A.html Reported-by: Bru Rom Contributions-by: Eric Rescorla and Ray Satiro
2016-06-22internals: rename the SessionHandle struct to Curl_easyDaniel Stenberg
2016-05-30URL parser: allow URLs to use one, two or three slashesDaniel Stenberg
Mostly in order to support broken web sites that redirect to broken URLs that are accepted by browsers. Browsers are typically even more leniant than this as the WHATWG URL spec they should allow an _infinite_ amount. I tested 8000 slashes with Firefox and it just worked. Added test case 1141, 1142 and 1143 to verify the new parser. Closes #791
2016-05-15ftp wildcard: segfault due to init only in multi_performDaniel Stenberg
The proper FTP wildcard init is now more properly done in Curl_pretransfer() and the corresponding cleanup in Curl_close(). The previous place of init/cleanup code made the internal pointer to be NULL when this feature was used with the multi_socket() API, as it was made within the curl_multi_perform() function. Reported-by: Jonathan Cardoso Machado Fixes #800
2016-05-13ConnectionExists: follow-up fix for proxy re-useMichael Kaufmann
Follow-up commit to 5823179 Closes #648
2016-05-09TLS: move the ALPN/NPN enable bits to the connectionDaniel Stenberg
Only protocols that actually have a protocol registered for ALPN and NPN should try to get that negotiated in the TLS handshake. That is only HTTPS (well, http/1.1 and http/2) right now. Previously ALPN and NPN would wrongly be used in all handshakes if libcurl was built with it enabled. Reported-by: Jay Satiro Fixes #789
2016-05-03connections: non-HTTP proxies on different ports aren't reused eitherDaniel Stenberg
Reported-by: Oleg Pudeyev and fuchaoqun Fixes #648
2016-05-01tls: make setting pinnedkey option fail if not supportedDaniel Stenberg
to make it obvious to users trying to use the feature with TLS backends not supporting it. Discussed in #781 Reported-by: Travis Burtrum
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
2016-04-25url.c: fixed DEBUGASSERT() for WinSock workaroundKarlson2k
If buffer is allocated, but nothing is received during prereceive stage, than number of processed bytes must be zero. Closes #778
2016-04-20url.c: Prefer we don't use explicit NULLs in conditionsSteve Holme
Fixed commit fa5fa65a30 to not use NULLs in if condition.
2016-04-20NTLM: check for NULL pointer before deferencingIsaac Boukris
At ConnectionExists, both check->proxyuser and check->proxypasswd could be NULL, so make sure to check first. Fixes #765
2016-04-20sendf.c: added ability to call recv() before send() as workaroundKarlson2k
WinSock destroys recv() buffer if send() is failed. As result - server response may be lost if server sent it while curl is still sending request. This behavior noticeable on HTTP server short replies if libcurl use several send() for request (usually for POST request). To workaround this problem, libcurl use recv() before every send() and keeps received data in intermediate buffer for further processing. Fixes: #657 Closes: #668
2016-04-18connect: implement TCP Fast Open for LinuxAlessandro Ghedini

2016-04-18url: add CURLOPT_TCP_FASTOPEN optionAlessandro Ghedini
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.
2016-04-09CURLOPT_SOCKS5_GSSAPI_SERVICE: Merged with CURLOPT_PROXY_SERVICE_NAMESteve Holme
As these two options provide identical functionality, the former for SOCK5 proxies and the latter for HTTP proxies, merged the two options together. As such CURLOPT_SOCKS5_GSSAPI_SERVICE is marked as deprecated as of 7.49.0.
2016-04-09url: Ternary operator code style changesSteve Holme

2016-04-08http_negotiate: Calculate service name and proxy service name locallySteve Holme
Calculate the service name and proxy service names locally, rather than in url.c which will allow for us to support overriding the service name for other protocols such as FTP, IMAP, POP3 and SMTP.

2016-03-30multi: move Curl_do and Curl_do_done to multi.c and make staticDaniel Stenberg
... called multi_do and multi_do_done as they're file local now.
2016-03-27http_ntlm: Renamed from curl_ntlm.[c|h]Steve Holme
Renamed the header and source files for this module as they are HTTP specific and as such, they should use the naming convention as other HTTP authentication source files do - this revert commit 260ee6b7bf. Note: We could also rename curl_ntlm_wb.[c|h], however, the Winbind code needs separating from the HTTP protocol and migrating into the vauth directory, thus adding support for Winbind to the SASL based protocols such as IMAP, POP3 and SMTP.
