Starting with Visual Studio 2013 (VC12) and Windows 8.1 the
GetVersionInfoEx() function has been marked as deprecated and it's

VerifyVersionInfo() where possible, which has been available since
Windows 2000.

bbc1705fa9 error message: Sensible message on timeout when transfer size unknown
A transfer timeout could result in an error message such as "Operation
timed out after 3000 milliseconds with 19 bytes of -1 received".  This
patch removes the non-sensical "of -1" when the size of the transfer
is unknown, mirroring the logic in lib/transfer.c

3b5c75ef3d OpenSSL: deselect weak ciphers by default
By default even recent versions of OpenSSL support and accept both
"export strength" ciphers, small-bitsize ciphers as well as downright
deprecated ones.

This change sets a default cipher set that avoids the worst ciphers, and
subsequently makes https://www.howsmyssl.com/a/check no longer grade
curl/OpenSSL connects as 'Bad'.

3b183df9cc multi: remove MULTI_TIMEOUT_INACCURACY
With the recently added timeout "reminder" functionality, there's no
reason left for us to execute timeout code before the time is
ripe. Simplifies the handling too.

This will make the *TIMEOUT and *CONNECTTIMEOUT options more accurate
again, which probably is most important when the *_MS versions are used.

In multi_socket, make sure to update 'now' after having handled activity
on a socket.

980659a2ca multi_socket: remind app if timeout didn't run
BACKGROUND:

We have learned that on some systems timeout timers are inaccurate and
might occasionally fire off too early. To make the multi_socket API work
with this, we made libcurl execute timeout actions a bit early too if
they are within our MULTI_TIMEOUT_INACCURACY. (added in commit
2c72732ebf, present since 7.21.0)

Switching everything to the multi API made this inaccuracy problem
slightly more notable as now everyone can be affected.

Recently (commit 21091549c0) we tweaked that inaccuracy value to make
timeouts more accurate and made it platform specific. We also figured
out that we have code at places that check for fixed timeout values so
they MUST NOT run too early as then they will not trigger at all (see
commit be28223f35 and a691e04470) - so there are definitately problems
with running timeouts before they're supposed to run. (We've handled
that so far by adding the inaccuracy margin to those specific timeouts.)

The libcurl multi_socket API tells the application with a callback that
a timeout expires in N milliseconds (and it explicitly will not tell it
again for the same timeout), and the application is then supposed to
call libcurl when that timeout expires. When libcurl subsequently gets
called with curl_multi_socket_action(...CURL_SOCKET_TIMEOUT...), it
knows that the application thinks the timeout expired - and alas, if it
is within the inaccuracy level libcurl will run code handling that
handle.

If the application says CURL_SOCKET_TIMEOUT to libcurl and _isn't_
within the inaccuracy level, libcurl will not consider the timeout
expired and it will not tell the application again since the timeout
value is still the same.

NOW:

This change introduces a modified behavior here. If the application says
CURL_SOCKET_TIMEOUT and libcurl finds no timeout code to run, it will
inform the application about the timeout value - *again* even if it is
the same timeout that it already told about before (although libcurl
will of course tell it the updated time so that it'll still get the
correct remaining time). This way, we will not risk that the application
believes it has done its job and libcurl thinks the time hasn't come yet
to run any code and both just sit waiting. This also allows us to
decrease the MULTI_TIMEOUT_INACCURACY margin, but that will be handled
in a separate commit.

A repeated timeout update to the application risk that the timeout will
then fire again immediately and we have what basically is a busy-loop
until the time is fine even for libcurl. If that becomes a problem, we
need to address it.

041d1e14d6 threaded-resolver: never use NULL hints with getaddrinfo
The net effect of this bug as it appeared to users, would be that
libcurl would timeout in the connect phase.

When disabling IPv6 use but still using getaddrinfo, libcurl would
wrongly not init the "hints" struct field in init_thread_sync() which
would subsequently lead to a getaddrinfo() invoke with a zeroed hints
with ai_socktype set to 0 instead of SOCK_STREAM. This would lead to
different behaviors on different platforms but basically incorrect
output.

This code was introduced in 483ff1ca75, released in curl 7.20.0.

This bug became a problem now due to the happy eyeballs code and how
libcurl now traverses the getaddrinfo() results differently.

8ae35102c4 ConnectionExists: fix NTLM check for new connection
When the requested authentication bitmask includes NTLM, we cannot
re-use a connection for another username/password as we then risk
re-using NTLM (connection-based auth).

This has the unfortunate downside that if you include NTLM as a possible
auth, you cannot re-use connections for other usernames/passwords even
if NTLM doesn't end up the auth type used.

4bb7400529 OpenSSL: Fix forcing SSLv3 connections
Some feedback provided by byte_bucket on IRC pointed out that commit
db11750cfa wasn’t really correct because it allows for “upgrading” to a
newer protocol when it should be only allowing for SSLv3.

This change fixes that.

When SSLv3 connection is forced, don't allow SSL negotiations for newer
versions.  Feedback provided by byte_bucket in #curl.  This behavior is
also consistent with the other force flags like --tlsv1.1 which doesn't
allow for TLSv1.2 negotiation, etc

2715d7f948 FILE: don't wait due to CURLOPT_MAX_RECV_SPEED_LARGE
The FILE:// code doesn't support this option - and it doesn't make sense
to support it as long as it works as it does since then it'd only block
even longer.

But: setting CURLOPT_MAX_RECV_SPEED_LARGE would make the transfer first
get done and then libcurl would wait until the average speed would get
low enough. This happened because the transfer happens completely in the
DO state for FILE:// but then it would still unconditionally continue in
to the PERFORM state where the speed check is made.

Starting now, the code will skip from DO_DONE to DONE immediately if no
socket is set to be recv()ed or send()ed to.

1dc43de0dc gtls: respect *VERIFYHOST independently of *VERIFYPEER
Security flaw CVE-2013-6422

This is conceptually the same problem and fix that 3c3622b6 brought to the
OpenSSL backend and that resulted in CVE-2013-4545.

This version of the problem was independently introduced to the GnuTLS
backend with commit 59cf93cc, present in the code since the libcurl
7.21.4 release.

be28223f35 multi: add timer inaccuracy margin to timeout/connecttimeout
Since all systems have inaccuracy in the timeout handling it is
imperative that we add an inaccuracy margin to the general timeout and
connecttimeout handling with the multi interface. This way, when the
timeout fires we should be fairly sure that it has passed the timeout
value and will be suitably detected.

For cases where the timeout fire before the actual timeout, we would
otherwise consume the timeout action and still not run the timeout code
since the condition wasn't met.

169fedbdce login options: remove the ;[options] support from CURLOPT_USERPWD
To avoid the regression when users pass in passwords containing semi-
colons, we now drop the ability to set the login options with the same
options. Support for login options in CURLOPT_USERPWD was added in
7.31.0.

Test case 83 was modified to verify that colons and semi-colons can be
used as part of the password when using -u (CURLOPT_USERPWD).

It is not 100% clear whether * should include clear text LOGIN or not
from RFC-5092, however, including it is then consistent with current
POP3 behaviour where clear text, APOP or SASL may be chosen.

75cd7fd667 imap: Fixed incorrect fallback to clear text authentication
If a specific SASL authentication mechanism was requested by the user
as part of the login options but wasn't supported by the server then
curl would fallback to clear text, when it shouldn't, rather than
reporting "No known authentication mechanisms supported" as the POP3
and SMTP protocols do.

7246dffff5 parsedate: avoid integer overflow
In C, signed integer overflow is undefined behavior. Thus, the compiler
is allowed to assume that it will not occur. In the check for an
overflow, the developer assumes that the signed integer of type time_t
will wrap around if it overflows. However, this behavior is undefined in
the C standard. Thus, when the compiler sees this, it simplifies t +
delta < t to delta < 0. Since delta > 0 and delta < 0 can't both be
true, the entire if statement is optimized out under certain
optimization levels. Thus, the parsedate function would return
PARSEDATE_OK with an undefined value in the time, instead of return -1 =
PARSEDATE_FAIL.

7d7df83198 Add "Happy Eyeballs" for IPv4/IPv6.
This patch invokes two socket connect()s nearly simultaneously, and
the socket that is first connected "wins" and is subsequently used for
the connection. The other is terminated.

There is a very slight IPv4 preference, in that if both sockets connect
simultaneously IPv4 is checked first and thus will win.

7de4cc35f8 email: Added initial support for cancelling authentication
Should a client application fail to decode an authentication message
received from a server, or not support any of the parameters given by
the server in the message, then the authentication phrase should be
cancelled gracefully by the client rather than simply terminating the
connection.

The authentication phrase should be cancelled by simply sending a '*'
to the server, in response to erroneous data being received, as per
RFC-3501, RFC-4954 and RFC-5034.

This patch adds the necessary state machine constants and appropriate
response handlers in order to add this functionality for the CRAM-MD5,
DIGEST-MD5 and NTLM authentication mechanisms.

d44b014271 FTP: make the data connection work when going through proxy
This is a regression since the switch to always-multi internally
c43127414d.

Test 1316 was modified since we now clearly call the Curl_client_write()
function when doing the LIST transfer part and then the
handler->protocol says FTP and ftpc.transfertype is 'A' which implies
text converting even though that the response is initially a HTTP
CONNECT response in this case.

0218a737fe ssh: Handle successful SSH_USERAUTH_NONE
According to the documentation for libssh2_userauth_list(), a NULL
return value is not necessarily an error. You must call
libssh2_userauth_authenticated() to determine if the SSH_USERAUTH_NONE
request was successful.

This fixes a segv when using sftp on a server that allows logins with an
empty password. When NULL was interpreted as an error, it would
free the session but not flag an error since the libssh2 errno would be
clear. This resulted in dereferencing a NULL session pointer.

ad34a2d5c8 SSL: protocol version can be specified more precisely
CURL_SSLVERSION_TLSv1_0, CURL_SSLVERSION_TLSv1_1,
CURL_SSLVERSION_TLSv1_2 enum values are added to force exact TLS version
(CURL_SSLVERSION_TLSv1 means TLS 1.x).

axTLS:
axTLS only supports TLS 1.0 and 1.1 but it cannot be set that only one
of these should be used, so we don't allow the new enum values.

darwinssl:
Added support for the new enum values.

SChannel:
Added support for the new enum values.

CyaSSL:
Added support for the new enum values.
Bug: The original CURL_SSLVERSION_TLSv1 value enables only TLS 1.0 (it
did the same before this commit), because CyaSSL cannot be configured to
use TLS 1.0-1.2.

GSKit:
GSKit doesn't seem to support TLS 1.1 and TLS 1.2, so we do not allow
those values.
Bugfix: There was a typo that caused wrong SSL versions to be passed to
GSKit.

NSS:
TLS minor version cannot be set, so we don't allow the new enum values.

QsoSSL:
TLS minor version cannot be set, so we don't allow the new enum values.

OpenSSL:
Added support for the new enum values.
Bugfix: The original CURL_SSLVERSION_TLSv1 value enabled only TLS 1.0,
now it enables 1.0-1.2.

Command-line tool:
Added command line options for the new values.

If no WINVER and/or _WIN32_IWNNT define was set, the Windows platform
SDK often defaults to high value, e.g. 0x601 (whoch may probably depend
on the Windows version being used, in my case Windows 7).

If WINVER >= 0x600 then winsock2.h includes some defines for WSAPoll(),
e.g. POLLIN, POLLPRI, POLLOUT etc. These defines clash with cURL's
lib/select.h.

Make sure HAVE_STRUCT_POLLFD is defined then.

Modified the selection logic so that XOAUTH2 will only be selected if

specifically asked for XOAUTH via the ;AUTH=XOAUTH login option or 2)
The bearer token is specified. Obviously if XOAUTH is asked for via
the login option but no token is specified the user will receive a
authentication failure which makes more sense than no known

2f9b64ac33 easy: rename struct monitor to socketmonitor

header file (sys/mon.h) which gets included via various standard headers
by lib/easy.c

cc-1101 cc: ERROR File = ../../curl/lib/easy.c, Line = 458
"monitor" has already been declared in the current scope.

a691e04470 multi_socket: improved 100-continue timeout handling
When waiting for a 100-continue response from the server, the
Curl_readwrite() will refuse to run if called until the timeout has been
reached.

We timeout code in multi_socket() allows code to run slightly before the
actual timeout time, so for test 154 it could lead to the function being
executed but refused in Curl_readwrite() and then the application would
just sit idling forever.

This was detected with runtests.pl -e on test 154.

460fb12097 security.h: rename to curl_sec.h to avoid name collision
I brought back security.h in commit bb55293313. As we actually
already found out back in 2005 in commit 62970da675, the file name
security.h causes problems so I renamed it curl_sec.h instead.

90ab65c632 smtp: added basic SASL XOAUTH2 support
Added the ability to use an XOAUTH2 bearer token [RFC6750] with SMTP for
authentication using RFC6749 "OAuth 2.0 Authorization Framework".

The bearer token is expected to be valid for the user specified in
conn->user. If CURLOPT_XOAUTH2_BEARER is defined and the connection has
an advertised auth mechanism of "XOAUTH2", the user and access token are
formatted as a base64 encoded string and sent to the server as
"AUTH XOAUTH2 <bearer token>".

bb55293313 FTP: remove krb4 support
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
