2017-10-22imap: if a FETCH response has no size, don't call write callbackDaniel Stenberg
CVE-2017-1000257 Reported-by: Brian Carpenter and 0xd34db347 Also detected by OSS-Fuzz: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=3586
2017-10-20ftp: reject illegal IP/port in PASV 227 responseDaniel Stenberg
... by using range checks. Among other things, this avoids an undefined behavior for a left shift that could happen on negative or very large values. Closes #1997 Detected by OSS-fuzz: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=3694
2017-10-20mime: do not reuse previously computed multipart sizePatrick Monnerat
The contents might have changed: size must be recomputed. Reported-by: moteus on github Fixes #1999
2017-10-19vtls: change struct Curl_ssl `close' field name to `close_one'.Patrick Monnerat
On OS/400, `close' is an ASCII system macro that corrupts the code if not used in a context not targetting the close() system API.
2017-10-19os400: add missing symbols in config file.Patrick Monnerat
Also adjust makefile to renamed files and warn about installation dirs mix-up.

2017-10-16setopt: range check most long optionsDaniel Stenberg
... filter early instead of risking "funny values" having to be dealt with elsewhere.
2017-10-16setopt: avoid integer overflows when setting millsecond valuesDaniel Stenberg
... that are multiplied by 1000 when stored. For 32 bit long systems, the max value accepted (2147483 seconds) is > 596 hours which is unlikely to ever be set by a legitimate application - and previously it didn't work either, it just caused undefined behavior. Also updated the man pages for these timeout options to mention the return code. Closes #1938
2017-10-15makefile.m32: allow to override gcc, ar and ranlibViktor Szakats
Allow to ovverride certain build tools, making it possible to use LLVM/Clang to build curl. The default behavior is unchanged. To build with clang (as offered by MSYS2), these settings can be used: CURL_CC=clang CURL_AR=llvm-ar CURL_RANLIB=llvm-ranlib Closes https://github.com/curl/curl/pull/1993
2017-10-15ldap: silence clang warningViktor Szakats
Use memset() to initialize a structure to avoid LLVM/Clang warning: ldap.c:193:39: warning: missing field 'UserLength' initializer [-Wmissing-field-initializers] Closes https://github.com/curl/curl/pull/1992

2017-10-11url: Update current connection SSL verify params in setoptArtak Galoyan
Now VERIFYHOST, VERIFYPEER and VERIFYSTATUS options change during active connection updates the current connection's (i.e.'connectdata' structure) appropriate ssl_config (and ssl_proxy_config) structures variables, making these options effective for ongoing connection. This functionality was available before and was broken by the following change: "proxy: Support HTTPS proxy and SOCKS+HTTP(s)" CommitId: cb4e2be7c6d42ca0780f8e0a747cecf9ba45f151.

2017-10-11openssl: don't use old BORINGSSL_YYYYMM macrosDavid Benjamin
Those were temporary things we'd add and remove for our own convenience long ago. The last few stayed around for too long as an oversight but have since been removed. These days we have a running BORINGSSL_API_VERSION counter which is bumped when we find it convenient, but 2015-11-19 was quite some time ago, so just check OPENSSL_IS_BORINGSSL. Closes #1979
2017-10-10smtp_done: free data before returning (on send failure)Daniel Stenberg

2017-10-09mime: properly unbind mime structure in curl_mime_free().Patrick Monnerat
This allows freeing a mime structure bound to the easy handle before curl_easy_cleanup(). Fixes #1970.

2017-10-08Revert "multi_done: wait for name resolve to finish if still ongoing"Daniel Stenberg
This reverts commit f3e03f6c0ac52a1bf396e03f7d7e9b5b3b7165fe. Caused memory leaks in the fuzzer, needs to be done differently. Disable test 1553 for now too, as it causes memory leaks without this commit!
2017-10-07remove_handle: call multi_done() first, then clear dns cache pointerDaniel Stenberg

2017-10-07multi_done: wait for name resolve to finish if still ongoingDaniel Stenberg
... as we must clean up memory.
2017-10-07pingpong: return error when trying to send without connectionDaniel Stenberg
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. Fixes #1953 Assisted-by: Max Dymond
2017-10-06vtls: fix warnings with --disable-crypto-authMarcel Raad
When CURL_DISABLE_CRYPTO_AUTH is defined, Curl_none_md5sum's parameters are not used.
2017-10-06multi_cleanup: call DONE on handles that never got thatDaniel Stenberg

2017-10-06lib/config-win32.h: let SMB/SMBS be enabled with OpenSSL/NSSViktor Szakats
The source code is now prepared to handle the case when both Win32 Crypto and OpenSSL/NSS crypto backends are enabled at the same time, making it now possible to enable `USE_WIN32_CRYPTO` whenever the targeted Windows version supports it. Since this matches the minimum Windows version supported by curl (Windows 2000), enable it unconditionally for the Win32 platform. This in turn enables SMB (and SMBS) protocol support whenever Win32 Crypto is available, regardless of what other crypto backends are enabled.

2017-10-04lib/Makefile.m32: allow customizing dll suffixesViktor Szakats
- New `CURL_DLL_SUFFIX` envvar will add a suffix to the generated libcurl dll name. Useful to add `-x64` to 64-bit builds so that it can live in the same directory as the 32-bit one. By default this is empty. - New `CURL_DLL_A_SUFFIX` envvar to customize the suffix of the generated import library (implib) for libcurl .dll. It defaults to `dll`, and it's useful to modify that to `.dll` to have the standard naming scheme for mingw-built .dlls, i.e. `libcurl.dll.a`. Closes https://github.com/curl/curl/pull/1942
2017-10-04failf: skip the sprintf() if there are no consumersDaniel Stenberg

2017-10-03vtls: compare and clone ssl configs properlyMichael Kaufmann
Compare these settings in Curl_ssl_config_matches(): - verifystatus (CURLOPT_SSL_VERIFYSTATUS) - random_file (CURLOPT_RANDOM_FILE) - egdsocket (CURLOPT_EGDSOCKET) Also copy the setting "verifystatus" in Curl_clone_primary_ssl_config(), and copy the setting "sessionid" unconditionally. This means that reusing connections that are secured with a client certificate is now possible, and the statement "TLS session resumption is disabled when a client certificate is used" in the old advisory at https://curl.haxx.se/docs/adv_20170419.html is obsolete.

2017-09-30Set and use more necessary options when some protocols are disabledDan Fandrich
When curl and libcurl are built with some protocols disabled, they stop setting and receiving some options that don't make sense with those protocols. In particular, when HTTP is disabled many options aren't set that are used only by HTTP. However, some options that appear to be HTTP-only are actually used by other protocols as well (some despite having HTTP in the name) and should be set, but weren't. This change now causes some of these options to be set and used for more (or for all) protocols. In particular, this fixes tests 646 through 649 in an HTTP-disabled build, which use the MIME API in the mail protocols.

2017-09-29connect: fix race condition with happy eyeballs timeoutAnders Bakken
The timer should be started after conn->connecttime is set. Otherwise the timer could expire without this condition being true: /* should we try another protocol family? */ if(i == 0 && conn->tempaddr[1] == NULL && curlx_tvdiff(now, conn->connecttime) >= HAPPY_EYEBALLS_TIMEOUT) { Ref: #1928

2017-09-28reuse_conn: don't copy flags that are known to be equalMichael Kaufmann
A connection can only be reused if the flags "conn_to_host" and "conn_to_port" match. Therefore it is not necessary to copy these flags in reuse_conn(). Closes #1918
