This patch adds CURLOPT_DNS_SHUFFLE_ADDRESSES to explicitly request
shuffling of IP addresses returned for a hostname when there is more
than one. This is useful when the application knows that a round robin
approach is appropriate and is willing to accept the consequences of
potentially discarding some preference order returned by the system's
implementation.

CVE-2018-1000120
Reported-by: Duy Phan Thanh
Bug: https://curl.haxx.se/docs/adv_2018-9cd6.html
When targeting x64, MinGW-w64 complains about conversions between
32-bit long and 64-bit pointers. Fix this by reusing the
GNUTLS_POINTER_TO_SOCKET_CAST / GNUTLS_SOCKET_TO_POINTER_CAST logic
from gtls.c, moving it to warnless.h as CURLX_POINTER_TO_INTEGER_CAST /
CURLX_INTEGER_TO_POINTER_CAST.

The "refresh" is for the -# output when no total transfer size is
known. It will now only use a single updated line even for this case:
The "-=O=-" ship moves when data is transferred. The four flying
"hashes" move (on a sine wave) on each refresh, independent of data.
vtls.c:multissl_init() might do a curl_free() call so strip that out to
make this work with more builds. We just want to verify that
memorytracking works so skipping one line is no harm.
A mime tree attached to an easy handle using CURLOPT_MIMEPOST is
strongly bound to the handle: there is a pointer to the easy handle in
each item of the mime tree and following the parent pointer list
of mime items ends in a dummy part stored within the handle.
Because of this binding, a mime tree cannot be shared between different
easy handles, thus it needs to be cloned upon easy handle duplication.
There is no way for the caller to get the duplicated mime tree
handle: it is then set to be automatically destroyed upon freeing the
new easy handle.
New test 654 checks proper mime structure duplication/release.
Add a warning note in curl_mime_data_cb() documentation about sharing
user data between duplicated handles.
Closes#2235

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.

Now that the form API is deprecated and not used anymore in curl tool,
a lot of its features left untested. Test 650 attempts to check all these
features not tested elsewhere.
curl_mime_encoder() is operational and documented.
curl tool -F option is extended with ";encoder=".
curl tool --libcurl option generates calls to curl_mime_encoder().
New encoder tests 648 & 649.
Test 1404 extended with an encoder specification.
This feature is badly supported in Windows: as a replacement, a caller has
to use curl_mime_data_cb() with fread, fseek and possibly fclose
callbacks to process opened files.
The cli tool and documentation are updated accordingly.
The feature is however kept internally for form API compatibility, with
the known caveats it always had.
As a side effect, stdin size is not determined by the cli tool even if
possible and this results in a chunked transfer encoding. Test 173 is
updated accordingly.
Additional mime-specific tests.
Existing tests updated to reflect small differences (Expect: 100-continue,
data size change due to empty lines, etc).
Option -F headers= keyword added to tests.
test1135 disabled until the entry point order change is resolved.
New example smtp-mime.
Examples postit2 and multi-post converted from form API to mime API.
Automake gets confused if you want to use C++ static libraries with C
code - basically we need to involve the clang++ linker. The easiest way
of achieving this is to rename the C code as C++ code. This gets us a
bit further along the path and ought to be compatible with Google's
version of clang.
- Start with the basic code from the ossfuzz project.
- Rewrite fuzz corpora to be binary files full of Type-Length-Value
data, and write a glue layer in the fuzzing function to convert
corpora into CURL options.
- Have supporting functions to generate corpora from existing tests
- Integrate with Makefile.am
Let's add a compile time safe API to select an SSL backend. This
function needs to be called *before* curl_global_init(), and can be
called only once.
Side note: we do not explicitly test that it is called before
curl_global_init(), but we do verify that it is not called multiple times
(even implicitly).
If SSL is used before the function was called, it will use whatever the
CURL_SSL_BACKEND environment variable says (or default to the first
available SSL backend), and if a subsequent call to
curl_global_sslset() disagrees with the previous choice, it will fail
with CURLSSLSET_TOO_LATE.
The function also accepts an "avail" parameter to point to a (read-only)
NULL-terminated list of available backends. This comes in real handy if
an application wants to let the user choose between whatever SSL backends
the currently available libcurl has to offer: simply call
curl_global_sslset(-1, NULL, &avail);
which will return CURLSSLSET_UNKNOWN_BACKEND and populate the avail
variable to point to the relevant information to present to the user.
Just like with the HTTP/2 push functions, we have to add the function
declaration of curl_global_sslset() function to the header file
*multi.h* because VMS and OS/400 require a stable order of functions
declared in include/curl/*.h (where the header files are sorted
alphabetically). This looks a bit funny, but it cannot be helped.

Also removed a TODO suggesting caching the precheck results. Tests
showed this would save about 0.1 sec on the total test run time on a
relatively modern system, an unnoticeable gain at the cost of longer and
more complicated code. There would also be a danger that a cached test
result would be inappropriately returned, such as when other test
dependencies (like environment variables) are different or when the
precheck causes side effects (like filesystem changes).

long is 32 bits while size_t is 64 bits on MinGW-w64, so
typecheck-gcc.h complains when using size_t for a long option.
Also, curl_socket_t is unsigned long long rather than int.

Windows does not allow setting the locale with environment variables (as
the test attempted to do), so the test failed when run with a user
locale that has a comma as radixchar. Changed the test to call
setlocale() explicitly to ensure that a known working locale is set even
on Windows.

Fix this by using the correct type.
This checks the new behavior of Curl_splaygetbest, so that the smallest
node not larger than the key is removed, and FIFO behavior is kept even
when there are multiple nodes with the same key.
Closes#1358
Multi handles repeatedly invert the queue of pending easy handles when
used with CURLMOPT_MAX_TOTAL_CONNECTIONS. This is caused by a multistep
process involving Curl_splaygetbest and violates the FIFO property of
the multi handle.
This patch fixes this issue by redefining the "best" node in the
context of timeouts as the "smallest not larger than now", and
implementing the necessary data structure modifications to do this
effectively, namely:
- splay nodes with the same key are now stored in a doubly-linked
circular list instead of a non-circular one to enable O(1)
insertion to the tail of the list
- Curl_splayinsert inserts nodes with the same key to the tail of
the same list
- in case of multiple nodes with the same key, the one on the head of
the list gets selected
system.h is aimed to replace curlbuild.h at a later point in time when
we feel confident system.h works sufficiently well.
curl/system.h is currently used in parallel with curl/curlbuild.h
curl/system.h determines a data sizes, data types and include file
status based on available preprocessor defines instead of getting
generated at build-time. This, in order to avoid relying on a build-time
generated file that makes it complicated to do 32 and 64 bit bields from
the same installed set of headers.
Test 1541 verifies that system.h comes to the same conclusion that
curlbuild.h offers.
Closes#1373
In ancient MinGW versions, in6addr_any was declared as extern, but not
defined. Because of that, 22a0c57746 added
definitions for in6addr_any when compiling with MinGW. The bug was fixed in
w32api version 3.6 from 2006, so this workaround is not needed anymore for
recent versions.
This fixes the following MinGW-w64 warnings because the MinGW-w64 version of
IN6ADDR_ANY_INIT has the two additional braces inside the macro:
util.c:59:14: warning: braces around scalar initializer
util.c:59:40: warning: excess elements in scalar initializer

Fixes#1354Closes#1357
When using basic-auth, connections and proxy connections
can be re-used with different Authorization headers since
it does not authenticate the connection (like NTLM does).
For instance, the below command should re-use the proxy
connection, but it currently doesn't:
curl -v -U alice:a -x http://localhost:8181http://localhost/
--next -U bob:b -x http://localhost:8181http://localhost/
This is a regression since refactoring of ConnectionExists()
as part of: cb4e2be7c6
Fix the above by removing the username and password compare
when re-using proxy connection at proxy_info_matches().
However, this fix brings back another bug would make curl
to re-print the old proxy-authorization header of previous
proxy basic-auth connection because it wasn't cleared.
For instance, in the below command the second request should
fail if the proxy requires authentication, but would succeed
after the above fix (and before aforementioned commit):
curl -v -U alice:a -x http://localhost:8181http://localhost/
--next -x http://localhost:8181http://localhost/
Fix this by clearing conn->allocptr.proxyuserpwd after use
unconditionally, same as we do for conn->allocptr.userpwd.
Also fix test 540 to not expect digest auth header to be
resent when connection is reused.

Depend on the known behaviour of URLs for nonexistent files rather than
the undefined behaviour of URLs for directories (which fails on Windows).
The test isn't about file: URLs at all, so the URL used doesn't really
matter.
If a % ended the statement, the string's trailing NUL would be skipped
and memory past the end of the buffer would be accessed and potentially
displayed as part of the --write-out output. Added tests 1440 and 1441

A client MUST ignore any Content-Length or Transfer-Encoding header
fields received in a successful response to CONNECT.
"Successful" described as: 2xx (Successful). RFC 7231 4.3.6
Prior to this change such a case would cause an error.
In some ways this bug appears to be a regression since c50b878. Prior to
that libcurl may have appeared to function correctly in such cases by
acting on those headers instead of causing an error. But that behavior
was also incorrect.

Test 1903 is doing HTTP pipelining, and that is a timing and ordering
sensitive operation and this fails far too often on the Travis CI
leading to people more or less ignoring test failures there. Not good.
The end of pipelning is probably coming sooner rather than later
anyway...
... because it causes confusion with users. Example URLs:
"http://[127.0.0.1]:11211:80" which a lot of languages' URL parsers will
parse and claim uses port number 80, while libcurl would use port number
11211.
"http://user@example.com:80@localhost" which by the WHATWG URL spec will
be treated to contain user name 'user@example.com' but according to
RFC3986 is user name 'user' for the host 'example.com' and then port 80
is followed by "@localhost"
Both these formats are now rejected, and verified so in test 1260.

This is likely to be the case when building from a tar ball release
package which includes a prebuilt man page. In that case, test the
packaged man page instead. This only makes a difference when building
out-of-tree (in-tree, the location in both cases is identical).
The character set in POSIX is set by the locale defined by (in
decreasing order of precedence) the LC_ALL, LC_CTYPE and LANG
environment variables (CHARSET was used by libidn but not libidn2).
LC_ALL is cleared to ensure that LC_CTYPE takes effect, but LC_ALL is
not used to set the locale to ensure that other parts of the locale
aren't overridden. Since there doesn't seem to be a cross-platform way
of specifying a UTF-8 locale, and not all systems may support UTF-8, a
<precheck> is used to skip the test if UTF-8 can't be verified to be
available. Test 1035 was also converted to UTF-8 for consistency, as
the actual character set used there is irrelevant to the test.
This patch uses a different UTF-8 locale than the last attempt, namely
en_US.UTF-8. This one has been verified on 7 different Linux and BSD
distributions and is more complete and usable than the locale UTF-8 (on
at least some systems).
This reverts commit ecd1d020ab.
That commit caused test failures on my Debian Linux machine for all
changed test cases. We need to reconsider how that should get done.
Character set in POSIX is set by the locale defined (in decreasing order
of precedence) by the LC_ALL, LC_CTYPE and LANG environment variables (I
believe CHARSET is only historic). LC_ALL is cleared to ensure that
LC_CTYPE takes effect, but LC_ALL is not used to set the locale to
ensure that other parts of the locale aren't overriden, if set. Since
there doesn't seem to be a cross-platform way of specifying a UTF-8
locale, and not all systems may support UTF-8, a <precheck> is used
(where relevant) to skip the test if UTF-8 isn't in use. Test 1035 was
also converted to UTF-8 for consistency, as the actual character set
used there is irrelevant to the test.

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

Closes#1140
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.
