2016-11-07s/cURL/curlDaniel Stenberg
We're mostly saying just "curl" in lower case these days so here's a big cleanup to adapt to this reality. A few instances are left as the project could still formally be considered called cURL.
2016-11-07http2: Don't send header fields prohibited by HTTP/2 specTatsuhiro Tsujikawa
Previously, we just ignored "Connection" header field. But HTTP/2 specification actually prohibits few more header fields. This commit ignores all of them so that we don't send these bad header fields. Bug: https://curl.haxx.se/mail/archive-2016-10/0033.html Reported-by: Ricki Hirner Closes https://github.com/curl/curl/pull/1092
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

2016-10-31strcase: make the tool use curl_str[n]equal insteadDaniel Stenberg
As they are after all part of the public API. Saves space and reduces complexity. Remove the strcase defines from the curlx_ family. Suggested-by: Dan Fandrich Idea: https://curl.haxx.se/mail/lib-2016-10/0136.html

2016-10-31strcasecompare: include curl.h in strcase.cDan Fandrich
This should fix the "warning: 'curl_strequal' redeclared without dllimport attribute: previous dllimport ignored" message and subsequent link error on Windows because of the missing CURL_EXTERN on the prototype.

2016-10-31curl_strequal: part of public API/ABI, needs to be keptDaniel Stenberg
These two public functions have been mentioned as deprecated since a very long time but since they are still part of the API and ABI we need to keep them around.

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 "-").

2016-10-31krb5: avoid realloc(0)Daniel Stenberg
If the requested size is zero, bail out with error instead of doing a realloc() that would cause a double-free: realloc(0) acts as a free() and then there's a second free in the cleanup path. CVE-2016-8619 Bug: https://curl.haxx.se/docs/adv_20161102E.html Reported-by: Cure53

2016-10-31cookies: getlist() now holds deep copies of all cookiesDaniel Stenberg
Previously it only held references to them, which was reckless as the thread lock was released so the cookies could get modified by other handles that share the same cookie jar over the share interface. CVE-2016-8623 Bug: https://curl.haxx.se/docs/adv_20161102I.html Reported-by: Cure53

2016-10-30mk-ca-bundle.vbs: Fix UTF-8 outputJay Satiro
- Change initial message box to mention delay when downloading/parsing. Since there is no progress meter it was somewhat unexpected that after choosing a filename nothing appears to happen, when actually the cert data is in the process of being downloaded and parsed. - Warn if OpenSSL is not present. - Use a UTF-8 stream to make the ca-bundle data. - Save the UTF-8 ca-bundle stream as binary so that no BOM is added. --- This is a follow-up to d2c6d15 which switched mk-ca-bundle.vbs output to ANSI due to corrupt UTF-8 output, now fixed. This change completes making the default certificate bundle output of mk-ca-bundle.vbs as close as possible to that of mk-ca-bundle.pl, which should make it easier to review any difference between their output.

2016-10-25mk-ca-bundle: Update the vbscript versionJay Satiro
Bring the VBScript version more in line with the perl version: - Change timestamp to UTC. - Change URL retrieval to HTTPS-only by default. - Comment out the options that disabled SSL cert checking by default. - Assume OpenSSL is present, get SHA256. And add a flag to toggle it. - Fix cert issuer name output. The cert issuer output is now ansi, converted from UTF-8. Prior to this it was corrupt UTF-8. It turns out though we can work with UTF-8 the FSO object that writes ca-bundle can't write UTF-8, so there will have to be some alternative if UTF-8 is needed (like an ADODB.Stream). - Disable the certificate text info feature. The certificate text info doesn't work properly with any recent OpenSSL.
2016-10-24mk-ca-bundle: Change URL retrieval to HTTPS-only by defaultJay Satiro
- Change all predefined Mozilla URLs to HTTPS (Gregory Szorc). - New option -k to allow URLs other than HTTPS and enable HTTP fallback. Prior to this change the default URL retrieval mode was to fall back to HTTP if HTTPS didn't work. Reported-by: Gregory Szorc Closes #1012
2016-10-22multi: force connections to get closed in close_all_connectionsDaniel Stenberg
Several independent reports on infinite loops hanging in the close_all_connections() function when closing a multi handle, can be fixed by first marking the connection to get closed before calling Curl_disconnect. This is more fixing-the-symptom rather than the underlying problem though. Bug: https://curl.haxx.se/mail/lib-2016-10/0011.html Bug: https://curl.haxx.se/mail/lib-2016-10/0059.html Reported-by: Dan Fandrich, Valentin David, Miloš Ljumović
2016-10-22curl_multi_remove_handle: fix a double-freeAnders Bakken
In short the easy handle needs to be disconnected from its connection at this point since the connection still is serving other easy handles. In our app we can reliably reproduce a crash in our http2 stress test that is fixed by this change. I can't easily reproduce the same test in a small example. This is the gdb/asan output: ==11785==ERROR: AddressSanitizer: heap-use-after-free on address 0xe9f4fb80 at pc 0x09f41f19 bp 0xf27be688 sp 0xf27be67c READ of size 4 at 0xe9f4fb80 thread T13 (RESOURCE_HTTP) #0 0x9f41f18 in curl_multi_remove_handle /path/to/source/3rdparty/curl/lib/multi.c:666 0xe9f4fb80 is located 0 bytes inside of 1128-byte region [0xe9f4fb80,0xe9f4ffe8) freed by thread T13 (RESOURCE_HTTP) here: #0 0xf7b1b5c2 in __interceptor_free /opt/toolchain/src/gcc-6.2.0/libsanitizer/asan/asan_malloc_linux.cc:45 #1 0x9f7862d in conn_free /path/to/source/3rdparty/curl/lib/url.c:2808 #2 0x9f78c6a in Curl_disconnect /path/to/source/3rdparty/curl/lib/url.c:2876 #3 0x9f41b09 in multi_done /path/to/source/3rdparty/curl/lib/multi.c:615 #4 0x9f48017 in multi_runsingle /path/to/source/3rdparty/curl/lib/multi.c:1896 #5 0x9f490f1 in curl_multi_perform /path/to/source/3rdparty/curl/lib/multi.c:2123 #6 0x9c4443c in perform /path/to/source/src/net/resourcemanager/ResourceManagerCurlThread.cpp:854 #7 0x9c445e0 in ... #8 0x9c4cf1d in ... #9 0xa2be6b5 in ... #10 0xf7aa5780 in asan_thread_start /opt/toolchain/src/gcc-6.2.0/libsanitizer/asan/asan_interceptors.cc:226 #11 0xf4d3a16d in __clone (/lib/i386-linux-gnu/libc.so.6+0xe716d) previously allocated by thread T13 (RESOURCE_HTTP) here: #0 0xf7b1ba27 in __interceptor_calloc /opt/toolchain/src/gcc-6.2.0/libsanitizer/asan/asan_malloc_linux.cc:70 #1 0x9f7dfa6 in allocate_conn /path/to/source/3rdparty/curl/lib/url.c:3904 #2 0x9f88ca0 in create_conn /path/to/source/3rdparty/curl/lib/url.c:5797 #3 0x9f8c928 in Curl_connect /path/to/source/3rdparty/curl/lib/url.c:6438 #4 0x9f45a8c in multi_runsingle /path/to/source/3rdparty/curl/lib/multi.c:1411 #5 0x9f490f1 in curl_multi_perform /path/to/source/3rdparty/curl/lib/multi.c:2123 #6 0x9c4443c in perform /path/to/source/src/net/resourcemanager/ResourceManagerCurlThread.cpp:854 #7 0x9c445e0 in ... #8 0x9c4cf1d in ... #9 0xa2be6b5 in ... #10 0xf7aa5780 in asan_thread_start /opt/toolchain/src/gcc-6.2.0/libsanitizer/asan/asan_interceptors.cc:226 #11 0xf4d3a16d in __clone (/lib/i386-linux-gnu/libc.so.6+0xe716d) SUMMARY: AddressSanitizer: heap-use-after-free /path/to/source/3rdparty/curl/lib/multi.c:666 in curl_multi_remove_handle Shadow bytes around the buggy address: 0x3d3e9f20: fd fd fd fd fd fd fd fd fd fd fd fd fd fd fd fd 0x3d3e9f30: fd fd fd fd fd fd fd fd fd fd fd fd fd fd fd fd 0x3d3e9f40: fd fd fd fd fd fd fd fd fd fd fd fd fd fd fd fd 0x3d3e9f50: fd fd fd fd fd fd fd fd fd fd fd fd fd fa fa fa 0x3d3e9f60: fa fa fa fa fa fa fa fa fa fa fa fa fa fa fa fa =>0x3d3e9f70:[fd]fd fd fd fd fd fd fd fd fd fd fd fd fd fd fd 0x3d3e9f80: fd fd fd fd fd fd fd fd fd fd fd fd fd fd fd fd 0x3d3e9f90: fd fd fd fd fd fd fd fd fd fd fd fd fd fd fd fd 0x3d3e9fa0: fd fd fd fd fd fd fd fd fd fd fd fd fd fd fd fd 0x3d3e9fb0: fd fd fd fd fd fd fd fd fd fd fd fd fd fd fd fd 0x3d3e9fc0: fd fd fd fd fd fd fd fd fd fd fd fd fd fd fd fd Shadow byte legend (one shadow byte represents 8 application bytes): Addressable: 00 Partially addressable: 01 02 03 04 05 06 07 Heap left redzone: fa Heap right redzone: fb Freed heap region: fd Stack left redzone: f1 Stack mid redzone: f2 Stack right redzone: f3 Stack partial redzone: f4 Stack after return: f5 Stack use after scope: f8 Global redzone: f9 Global init order: f6 Poisoned by user: f7 Container overflow: fc Array cookie: ac Intra object redzone: bb ASan internal: fe Left alloca redzone: ca Right alloca redzone: cb ==11785==ABORTING Thread 14 "RESOURCE_HTTP" received signal SIGABRT, Aborted.

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.
