2015-05-20read_callback: move to SessionHandle from connectdataDaniel Stenberg
With many easy handles using the same connection for multiplexing, it is important we store and keep the transfer-oriented stuff in the SessionHandle so that callbacks and callback data work fine even when many easy handles share the same physical connection.
2015-05-18http2: fix build when NOT h2-enabledDaniel Stenberg
2015-05-18pipeline: switch some code over to functionsDaniel Stenberg
... to "compartmentalize" a bit and make it easier to change behavior when multiplexing is used instead of good old pipelining.
2015-05-18CURLOPT_PIPEWAIT: addedDaniel Stenberg
By setting this option to 1 libcurl will wait for a connection to reveal if it is possible to pipeline/multiplex on before it continues.
2015-05-18IsPipeliningPossible: fixed for http2Daniel Stenberg
2015-05-18http2: remove the stream from the hash in stream_close callbackDaniel Stenberg
... and suddenly things work much better!
2015-05-18http2: set default concurrency, fix ConnectionExists for multiplexDaniel Stenberg
2015-05-18bundles: store no/default/pipeline/multiplexDaniel Stenberg
to allow code to act differently on the situation. Also added some more info message for the connection re-use function to make it clearer when connections are not re-used.
2015-05-18http2: separate multiplex/pipelining + cleanup memory leaksDaniel Stenberg
2015-05-18CURLMOPT_PIPELINE: bit 1 is for multiplexingDaniel Stenberg
2015-05-18pipeline: move function to pipeline.c and make staticDaniel Stenberg
... as it was only used from there.
2015-05-18IsPipeliningPossible: http2 can always "pipeline" (multiplex)Daniel Stenberg
2015-05-18http2: force "drainage" of streamsDaniel Stenberg
... which is necessary since the socket won't be readable but there is data waiting in the buffer.
2015-05-18http2: move the mem+len pair to the stream structDaniel Stenberg
2015-05-12bundles: merged into conncache.cDaniel Stenberg
All the existing Curl_bundle* functions were only ever used from within the conncache.c file, so I moved them over and made them static (and removed the Curl_ prefix).
2015-05-12hostcache: made all host caches use structs, not pointersDaniel Stenberg
This avoids unnecessary dynamic allocs and as this also removed the last users of *hash_alloc() and *hash_destroy(), those two functions are now removed.
2015-05-12connection cache: avoid Curl_hash_alloc()Daniel Stenberg
... by using plain structs instead of pointers for the connection cache, we can avoid several dynamic allocations that weren't necessary.
2015-04-28CURLOPT_HEADEROPT: default to separateDaniel Stenberg
Make the HTTP headers separated by default for improved security and reduced risk for information leakage. Bug: http://curl.haxx.se/docs/adv_20150429.html Reported-by: Yehezkel Horowitz, Oren Souroujon
2015-04-28Negotiate: custom service names for SPNEGO.Linus Nielsen
* Add new options, CURLOPT_PROXY_SERVICE_NAME and CURLOPT_SERVICE_NAME. * Add new curl options, --proxy-service-name and --service-name.
2015-04-27ConnectionExists: call it multi-use instead of pipeliningDaniel Stenberg
So that it fits HTTP/2 as well
2015-04-22connectionexists: follow-up to fd9d3a1ef1fDaniel Stenberg
PROTOPT_CREDSPERREQUEST still needs to be checked even when NTLM is not enabled. Mistake-caught-by: Kamil Dudka
2015-04-22connectionexists: fix build without NTLMDaniel Stenberg
Do not access NTLM-specific struct fields when built without NTLM enabled! bug: http://curl.haxx.se/?i=231 Reported-by: Patrick Rapin
2015-04-21fix_hostname: zero length host name caused -1 index offsetDaniel Stenberg
If a URL is given with a zero-length host name, like in "http://:80" or just ":80", `fix_hostname()` will index the host name pointer with a -1 offset (as it blindly assumes a non-zero length) and both read and assign that address. CVE-2015-3144 Bug: http://curl.haxx.se/docs/adv_20150422D.html Reported-by: Hanno Böck
2015-04-21ConnectionExists: for NTLM re-use, require credentials to matchDaniel Stenberg
CVE-2015-3143 Bug: http://curl.haxx.se/docs/adv_20150422A.html Reported-by: Paras Sethia
2015-03-27url: Don't accept CURLOPT_SSLVERSION unless USE_SSL is definedJay Satiro
2015-03-24CURLOPT_PATH_AS_IS: addedDaniel Stenberg
--path-as-is is the command line option Added docs in curl.1 and CURLOPT_PATH_AS_IS.3 Added test in test 1241
2015-03-20url: add CURLOPT_SSL_FALSESTART optionAlessandro Ghedini
This option can be used to enable/disable TLS False Start defined in the RFC draft-bmoeller-tls-falsestart.
2015-03-17checksrc: use space after commaDaniel 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 a few calls of cURL functionsMarkus Elfring
The following functions return immediately if a null pointer was passed. * Curl_cookie_cleanup * curl_formfree It is therefore not needed that a function caller repeats a corresponding check. This issue was fixed by using the software Coccinelle 1.0.0-rc24. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net>
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.

2015-03-11proxy: re-use proxy connections (regression)Daniel Stenberg
When checking for a connection to re-use, a proxy-using request must check for and use a proxy connection and not one based on the host name! Added test 1421 to verify Bug: http://curl.haxx.se/bug/view.cgi?id=1492
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.
2015-02-20configure: allow both --with-ca-bundle and --with-ca-pathJulian Ospald
SSL_CTX_load_verify_locations by default (and if given non-Null parameters) searches the CAfile first and falls back to CApath. This allows for CAfile to be a basis (e.g. installed by the package manager) and CApath to be a user configured directory. This wasn't reflected by the previous configure constraint which this patch fixes. Bug: https://github.com/bagder/curl/pull/139
2015-01-16url: add CURLOPT_SSL_VERIFYSTATUS optionAlessandro Ghedini
This option can be used to enable/disable certificate status verification using the "Certificate Status Request" TLS extension defined in RFC6066 section 8. This also adds the CURLE_SSL_INVALIDCERTSTATUS error, to be used when the certificate status verification fails, and the Curl_ssl_cert_status_request() function, used to check whether the SSL backend supports the status_request extension.

2014-12-17parseurlandfillconn(): fix improper non-numeric scope_id stripping.Kyle J. McKay
Fixes SF bug 1149: http://sourceforge.net/p/curl/bugs/1449/
2014-12-16IPV6: address scope != scope idPatrick Monnerat
There was a confusion between these: this commit tries to disambiguate them. - Scope can be computed from the address itself. - Scope id is scope dependent: it is currently defined as 1-based local interface index for link-local scoped addresses, and as a site index(?) for (obsolete) site-local addresses. Linux only supports it for link-local addresses. The URL parser properly parses a scope id as an interface index, but stores it in a field named "scope": confusion. The field has been renamed into "scope_id". Curl_if2ip() used the scope id as it was a scope. This caused failures to bind to an interface. Scope is now computed from the addresses and Curl_if2ip() matches them. If redundantly specified in the URL, scope id is check for mismatch with the interface index. This commit should fix SF bug #1451.
2014-12-12smb: Disable SMB when 64-bit integers are not supportedSteve Holme
This fixes compilation issues with compilers that don't support 64-bit integers through long long or __int64.

url.c:3078: warning: variable 'credentialsMatch' set but not used
2014-12-09cookies: Improved OOM handling in cookiesDan Fandrich
This fixes the test 506 torture test. The internal cookie API really ought to be improved to separate cookie parsing errors (which may be ignored) with OOM errors (which should be fatal).
2014-12-07smb: Fixed Windows autoconf builds following commit eb88d778e7Steve Holme
As Windows based autoconf builds don't yet define USE_WIN32_CRYPTO either explicitly through --enable-win32-cypto or automatically on _WIN32 based platforms, subsequent builds broke with the following error message: "Can't compile NTLM support without a crypto library."
2014-12-07smb: Build with SSPI enabledBill Nagel

2014-12-04libcurl: add UNIX domain sockets supportPeter Wu
The ability to do HTTP requests over a UNIX domain socket has been requested before, in Apr 2008 [0][1] and Sep 2010 [2]. While a discussion happened, no patch seems to get through. I decided to give it a go since I need to test a nginx HTTP server which listens on a UNIX domain socket. One patch [3] seems to make it possible to use the CURLOPT_OPENSOCKETFUNCTION function to gain a UNIX domain socket. Another person wrote a Go program which can do HTTP over a UNIX socket for Docker[4] which uses a special URL scheme (though the name contains cURL, it has no relation to the cURL library). This patch considers support for UNIX domain sockets at the same level as HTTP proxies / IPv6, it acts as an intermediate socket provider and not as a separate protocol. Since this feature affects network operations, a new feature flag was added ("unix-sockets") with a corresponding CURL_VERSION_UNIX_SOCKETS macro. A new CURLOPT_UNIX_SOCKET_PATH option is added and documented. This option enables UNIX domain sockets support for all requests on the handle (replacing IP sockets and skipping proxies). A new configure option (--enable-unix-sockets) and CMake option (ENABLE_UNIX_SOCKETS) can disable this optional feature. Note that I deliberately did not mark this feature as advanced, this is a feature/component that should easily be available.

This patch enables SMB/CIFS support in libcurl.
2014-11-09build: Fixed no NTLM support for email when CURL_DISABLE_HTTP is definedSteve Holme
USE_NTLM would only be defined if: HTTP support was enabled, NTLM and cryptography weren't disabled, and either a supporting cryptography library or Windows SSPI was being compiled against. This means it was not possible to build libcurl without HTTP support and use NTLM for other protocols such as IMAP, POP3 and SMTP. Rather than introduce a new SASL pre-processor definition, removed the HTTP prerequisite just like USE_SPNEGO and USE_KRB5. Note: Winbind support still needs to be dependent on CURL_DISABLE_HTTP as it is only available to HTTP at present. This bug dates back to August 2011 when I started to add support for NTLM to SMTP.
