2017-02-21url: Improve CURLOPT_PROXY_CAPATH error handlingJay Satiro
- Change CURLOPT_PROXY_CAPATH to return CURLE_NOT_BUILT_IN if the option is not supported, which is the same as what we already do for CURLOPT_CAPATH. - Change the curl tool to handle CURLOPT_PROXY_CAPATH error CURLE_NOT_BUILT_IN as a warning instead of as an error, which is the same as what we already do for CURLOPT_CAPATH. - Fix CAPATH docs to show that CURLE_NOT_BUILT_IN is returned when the respective CAPATH option is not supported by the SSL library.

2017-02-21TLS: make SSL_VERIFYSTATUS work againDaniel Stenberg
The CURLOPT_SSL_VERIFYSTATUS option was not properly handled by libcurl and thus even if the status couldn't be verified, the connection would be allowed and the user would not be told about the failed verification. Regression since cb4e2be7c6d42ca CVE-2017-2629 Bug: https://curl.haxx.se/docs/adv_20170222.html Reported-by: Marcus Hoffmann
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

2017-01-19CURLOPT_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
2017-01-18CURLOPT_CONNECT_TO: Fix compile warningsMichael Kaufmann
Fix compile warnings that appeared only when curl has been configured with '--disable-verbose'.
2017-01-18parseurl: move back buffer to function scopeDaniel Stenberg
Regression since 1d4202ad, which moved the buffer into a more narrow scope, but the data in that buffer was used outside of that more narrow scope. Reported-by: Dan Fandrich Bug: https://curl.haxx.se/mail/lib-2017-01/0093.html
2017-01-13unix_socket: add support for abstract unix domain socketIsaac Boukris
In addition to unix domain sockets, Linux also supports an abstract namespace which is independent of the filesystem. In order to support it, add new CURLOPT_ABSTRACT_UNIX_SOCKET option which uses the same storage as CURLOPT_UNIX_SOCKET_PATH internally, along with a flag to specify abstract socket. On non-supporting platforms, the abstract address will be interpreted as an empty string and fail gracefully. Also add new --abstract-unix-socket tool parameter.

2017-01-13IDN: revert use of the transitional optionDaniel Stenberg
It made the german ß get converted to ss, IDNA2003 style, and we can't have that for the .de TLD - a primary reason for our switch to IDNA2008. Test 165 verifies.

2017-01-13url: --noproxy option overrides NO_PROXY environment variableERAMOTO Masaya
Under condition using http_proxy env var, noproxy list was the combination of --noproxy option and NO_PROXY env var previously. Since this commit, --noproxy option overrides NO_PROXY environment variable even if use http_proxy env var. Closes #1140
2017-01-13url: Refactor detect_proxy()ERAMOTO Masaya
If defined CURL_DISABLE_HTTP, detect_proxy() returned NULL. If not defined CURL_DISABLE_HTTP, detect_proxy() checked noproxy list. Thus refactor to set proxy to NULL instead of calling detect_proxy() if define CURL_DISABLE_HTTP, and refactor to call detect_proxy() if not define CURL_DISABLE_HTTP and the host is not in the noproxy list.
2017-01-13url: Fix NO_PROXY env var to work properly with --proxy option.ERAMOTO Masaya
The combination of --noproxy option and http_proxy env var works well both for proxied hosts and non-proxied hosts. However, when combining NO_PROXY env var with --proxy option, non-proxied hosts are not reachable while proxied host is OK. This patch allows us to access non-proxied hosts even if using NO_PROXY env var with --proxy option.

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.

2016-11-11URL-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

2016-10-18select: 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).

2016-09-22New libcurl option to keep sending on errorMichael Kaufmann

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

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.
