* timediff: make it 64 bit (if possible) even with 32 bit time_tDaniel Stenberg2019-08-011-2/+2
| | | | | | | ... to make it hold microseconds too. Fixes #4165 Closes #4168
* cleanup: remove the 'numsocks' argument used in many placesDaniel Stenberg2019-07-301-7/+2
| | | | | | | | | It was used (intended) to pass in the size of the 'socks' array that is also passed to these functions, but was rarely actually checked/used and the array is defined to a fixed size of MAX_SOCKSPEREASYHANDLE entries that should be used instead. Closes #4169
* pingpong: ignore regular timeout in disconnect phaseDaniel Stenberg2018-12-171-4/+5
| | | | | | | | | | | The timeout set with CURLOPT_TIMEOUT is no longer used when disconnecting from one of the pingpong protocols (FTP, IMAP, SMTP, POP3). Reported-by: jasal82 on github Fixes #3264 Closes #3374
* Curl_debug: remove dead printhost codeDaniel Stenberg2018-06-121-4/+3
| | | | | | | | | 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
* cppcheck: fix warningsMarian Klymov2018-06-111-2/+1
| | | | | | | | | | | | | - 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
* pingpong: fix response cache memcpy overflowDaniel Stenberg2018-05-141-1/+4
| | | | | | | | | | | Response data for a handle with a large buffer might be cached and then used with the "closure" handle when it has a smaller buffer and then the larger cache will be copied and overflow the new smaller heap based buffer. Reported-by: Dario Weisser CVE: CVE-2018-1000300 Bug: https://curl.haxx.se/docs/adv_2018-82c2.html
* time: rename Curl_tvnow to Curl_nowDaniel Stenberg2017-10-251-6/+6
| | | | | | | | | | ... since the 'tv' stood for timeval and this function does not return a timeval struct anymore. Also, cleaned up the Curl_timediff*() functions to avoid typecasts and clean up the descriptive comments. Closes #2011
* timediff: return timediff_t from the time diff functionsDaniel Stenberg2017-10-251-2/+2
| | | | | | | | | | | | | | | ... to cater for systems with unsigned time_t variables. - Renamed the functions to curlx_timediff and Curl_timediff_us. - Added overflow protection for both of them in either direction for both 32 bit and 64 bit time_ts - Reprefixed the curlx_time functions to use Curl_* Reported-by: Peter Piekarski Fixes #2004 Closes #2005
* pingpong: return error when trying to send without connectionDaniel Stenberg2017-10-071-2/+9
| | | | | | | | | | | | | When imap_done() got called before a connection is setup, it would try to "finish up" and dereffed a NULL pointer. Test case 1553 managed to reproduce. I had to actually use a host name to try to resolve to slow it down, as using the normal local server IP will make libcurl get a connection in the first curl_multi_perform() loop and then the bug doesn't trigger.

* proxy: Support HTTPS proxy and SOCKS+HTTP(s)Alex Rousskov2016-11-241-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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.
* lib: fix compiler warnings after de4de4e3c7cMarcel Raad2016-11-181-5/+5
| | | | | | | | | 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
* select: switch to macros in uppercaseDaniel Stenberg2016-10-181-1/+2
| | | | | | | | | | 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.
* internals: rename the SessionHandle struct to Curl_easyDaniel Stenberg2016-06-221-4/+4
|
* lib: include curl_printf.h as one of the last headersDaniel Stenberg2016-04-291-2/+2
| | | | | | | | | | | | | | | | | | | | 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

* Bug #149: Deletion of unnecessary checks before calls of the function "free"Markus Elfring2015-03-161-4/+2
| | | | | | | | | | | 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. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net>
* mprintf.h: remove #ifdef CURLDEBUGDaniel Stenberg2015-03-031-4/+2
| | | | | ... and as a consequence, introduce curl_printf.h with that re-define magic instead and make all libcurl code use that instead.
* code cleanup: we prefer 'CURLcode result'Daniel Stenberg2014-10-241-19/+17
| | | | | | | | | | | | | | ... 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)
* Curl_pp_flushsend: skip superfluous assignmentDaniel Stenberg2014-10-241-4/+2
| | | | Detected by cppcheck.
* Curl_pp_readresp: remove superfluous assignmentDaniel Stenberg2014-10-241-3/+1
| | | | | | Variable already assigned a few lines up. Detected by cppcheck.
* Curl_pp_readresp: use memmove not memcpy, possibly overlapping areasDaniel Stenberg2013-12-241-1/+1
| | | | Fixes commit 1deac31eba7
* Curl_pp_readresp: replace stupid loop with memcpyDaniel Stenberg2013-12-221-4/+2
|
* Curl_pp_readresp: zero terminate lineDaniel Stenberg2013-12-221-1/+1
| | | | | | | | | The comment in the code mentions the zero terminating after having copied data, but it mistakingly zero terminated the source data and not the destination! This caused the test 864 problem discussed on the list: http://curl.haxx.se/mail/lib-2013-12/0113.html Signed-off-by: Daniel Stenberg <daniel@haxx.se>

* pingpong: Check SSL library buffers for already read dataJiri Hruska2013-09-091-0/+4
| | | | | | Otherwise the connection can get stuck during various phases, waiting for new data on the socket using select() etc., but it will never be received as the data has already been read into SSL library.
* FTP: remove krb4 supportDaniel Stenberg2013-08-251-8/+7
| | | | | | | | | | We've announced this pending removal for a long time and we've repeatedly asked if anyone would care or if anyone objects. Nobody has objected. It has probably not even been working for a good while since nobody has tested/used this code recently. The stuff in krb4.h that was generic enough to be used by other sources is now present in security.h
* pingpong.c: Fix enumerated type mixed with another typeSteve Holme2013-03-031-2/+2

* Fixed checking the socket if there is data waiting in the cacheJiri Hruska2013-02-221-3/+7
| | | | | | Use Curl_pp_moredata() in Curl_pp_multi_statemach() to check if there is more data to be received, rather than the socket state, as a task could hang waiting for more data from the socket itself.
* pingpong: Introduce Curl_pp_moredata()Jiri Hruska2013-02-221-0/+4
| | | | | | | | | | | | | | A simple function to test whether the PP is not sending and there are still more data in its receiver cache. This will be later utilized to: 1) Change Curl_pp_multi_statemach() and Curl_pp_easy_statemach() to not test socket state and just call user's statemach_act() function when there are more data to process, because otherwise the task would just hang, waiting for more data from the socket. 2) Allow PP users to read multiple responses by looping as long as there are more data available and current phase is not finished. (Currently needed for correct processing of IMAP SELECT responses.)
* compiler warning fix: declaration of 'wait' shadows a global declarationDaniel Stenberg2013-02-181-3/+3
| | | | | | | | It seems older gcc installations (at least) will cause warnings if we name a variable 'wait'. Now changed to 'block' instead. Reported by: Jiří Hruška Bug: http://curl.haxx.se/mail/lib-2013-02/0247.html
* rename "easy" statemachines: call them block insteadDaniel Stenberg2013-02-151-52/+22
| | | | | | ... since they're not used by the easy interface really, I wanted to remove the association. Also, I unified the pingpong statemachine driver into a single function with a 'wait' argument: Curl_pp_statemach.
* pingpong: Optimised the endofresp() functionSteve Holme2013-02-121-1/+1
| | | | | | | | | | Reworked the pp->endofresp() function so that the conndata, line and line length are passed down to it just as with Curl_client_write() rather than each implementation of the function having to query these values. Additionally changed the int return type to bool as this is more representative of the function's usage.
* build: fix circular header inclusion with other packagesYang Tse2013-01-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit renames lib/setup.h to lib/curl_setup.h and renames lib/setup_once.h to lib/curl_setup_once.h. Removes the need and usage of a header inclusion guard foreign to libcurl. [1] Removes the need and presence of an alarming notice we carried in old setup_once.h [2] ---------------------------------------- 1 - lib/setup_once.h used __SETUP_ONCE_H macro as header inclusion guard up to commit ec691ca3 which changed this to HEADER_CURL_SETUP_ONCE_H, this single inclusion guard is enough to ensure that inclusion of lib/setup_once.h done from lib/setup.h is only done once. Additionally lib/setup.h has always used __SETUP_ONCE_H macro to protect inclusion of setup_once.h even after commit ec691ca3, this was to avoid a circular header inclusion triggered when building a c-ares enabled version with c-ares sources available which also has a setup_once.h header. Commit ec691ca3 exposes the real nature of __SETUP_ONCE_H usage in lib/setup.h, it is a header inclusion guard foreign to libcurl belonging to c-ares's setup_once.h The renaming this commit does, fixes the circular header inclusion, and as such removes the need and usage of a header inclusion guard foreign to libcurl. Macro __SETUP_ONCE_H no longer used in libcurl. 2 - Due to the circular interdependency of old lib/setup_once.h and the c-ares setup_once.h header, old file lib/setup_once.h has carried back from 2006 up to now days an alarming and prominent notice about the need of keeping libcurl's and c-ares's setup_once.h in sync. Given that this commit fixes the circular interdependency, the need and presence of mentioned notice is removed. All mentioned interdependencies come back from now old days when the c-ares project lived inside a curl subdirectory. This commit removes last traces of such fact.

* FTP: prevent the multi interface from blockingDaniel Stenberg2012-11-041-1/+4
| | | | | | | | | | | | | | | As pointed out in Bug report #3579064, curl_multi_perform() would wrongly use a blocking mechanism internally for some commands which could lead to for example a very long block if the LIST response never showed. The solution was to make sure to properly continue to use the multi interface non-blocking state machine. The new test 1501 verifies the fix.
