The code rejected 0 as a valid timeout while in fact the function could
indeed legitimately return that and it should be respected.

A base64 string should be a multiple of 4 characters in length, not
contain any more than 2 padding characters and only contain padding
characters at the end of string. For example: Y3VybA==
Strings such as the following are considered invalid:
Y= - Invalid length
Y== - Invalid length
Y=== - More than two padding characters
Y=x= - Padding character contained within string
This patch fixes a bug in Happy Eyeballs where curl would wait for a
connect response from socket1 before checking socket2.
Also, it updates error messages for failed connections, showing the ip
addresses that failed rather than just the host name repeatedly.

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.
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.
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.
This workaround had been previously been implemented for IMAP and POP3
but not SMTP. Some of the recent test case additions implemented this
behaviour to emulate a bad server and the SMTP code didn't cope with it.
... if not already initialized. This fixes a regression introduced by
commit 4ad8e142da, which caused test619
to intermittently fail on certain machines (namely Fedora build hosts).
Changed the failure code when TLS v1.1 and v1.2 is requested but not
supported by older OpenSSL versions, following review from libcurl
peers, and reduced the number of required preprocessor if statements.
...with the use of CURL_SSLVERSION_TLSv1_1 and CURL_SSLVERSION_TLSv1_2
being conditional on OpenSSL v1.0.1 as the appropriate flags are not
supported under earlier versions.
Commit ad34a2d5c8 relies on definitions that are only present in
OpenSSL v1.0.1 and up. This quick fix allows the builds that use
older versions of OpenSSL to continue building.
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.

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.
Setting only CURLOPT_SSL_VERIFYHOST without CURLOPT_SSL_VERIFYPEER set
should still verify that the host name fields in the server certificate
is fine or return failure.

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.

Moved the standard SASL mechanism strings into curl_sasl.h rather than
hard coding the same values over and over again in the protocols that
use SASL authentication.
For more information about the mechanism strings see:

In ossl_connect_step2() when the "Unknown SSL protocol error" occurs, it
would output the local port number instead of the remote one which
showed when doing SSL over a proxy (but with the correct remote host
name). As libcurl only speaks SSL to the remote we know it is the remote
port.

Added the ability to use an XOAUTH2 bearer token [RFC6750] with POP3 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>".
iOS 7 finally added the option to enable 1/n-1 when using TLS 1.0
and a CBC cipher, so we now always turn that on unless the user
manually turns it off using CURLSSLOPT_ALLOW_BEAST.
It appears Apple also added some new PSK ciphers, but no interface to
use them yet, so we at least support printing them if we find them.
Implement: Expired Cookies These following situation, curl removes
cookie(s) from struct CookieInfo if the cookie expired.
- Curl_cookie_add()
- Curl_cookie_getlist()
- cookie_output()
Solaris with the SunStudio Compiler is reportedly missing this define,
but as we're using it without any good reason on all the places it was
used I've now instead switched to just use sensible buffer sizes that
fit a 32 bit decimal number. Which also happens to be smaller than the
common NI_MAXSERV value which is 32 on most machines.

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.
The transfer size would be calculated incorrectly if the email contained
within the FETCH response, had been partially received by the pingpong
layer. As such the following, example output, would be seen if the
amount remaining was smaller than the amount received:
* Excess found in a non pipelined read: excess = 1394, size = 262,
maxdownload = 262, bytecount = 1374
* transfer closed with -1112 bytes remaining to read

When building the code using LLVM Clang without NGHTTP2, I was getting
this warning:
../lib/http.h:155:1: warning: empty struct is a GNU extension [-Wgnu]
Placing a dummy variable into the data structure silenced the warning.
Recent OpenSSL uses user interface abstraction to negotiate access to
private keys in the cryprographical engines. An OpenSSL application is
expected to implement the user interface. Otherwise a default one
provided by OpenSSL (interactive standard I/O) will be used and the
aplication will have no way how to pass a password to the engine.

Using the first little merge of nghttp2 into libcurl, I stumbeled on the
missing 'snprintf' in MSVCRT. Isn't this how we do it for other libcurl
files? I.e. use 'curl_msnprintf' and not 'snprintf' directly:

XOAUTH2 would be selected in preference to LOGIN and PLAIN if the IMAP
or SMTP server advertised support for it even though a user's password
was supplied but bearer token wasn't.
Modified the selection logic so that XOAUTH2 will only be selected if
the server supports it and A) The curl user/libcurl programmer has
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
authentication mechanisms supported!

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.
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.
