"Any two of the parameters, readfds, writefds, or exceptfds, can be

When using select(), cURL doesn't adhere to this (WinSock-specific)
rule, and can ask to monitor empty fd_sets, which leads to select()
returning WSAEINVAL (i.e. EINVAL) and connections failing in mysterious
ways as a result (at least when using the curl_multi_socket_action()
interface).

OpenSSL passes out and outlen variable uninitialized to
select_next_proto_cb callback function. If the callback function
returns SSL_TLSEXT_ERR_OK, the caller assumes the callback filled
values in out and outlen and processes as such. Previously, if there
is no overlap in protocol lists, curl code does not fill any values in
these variables and returns SSL_TLSEXT_ERR_OK, which means we are
triggering undefined behavior. valgrind warns this.
This patch fixes this issue by fallback to HTTP/1.1 if there is no
overlap.
Make all code use connclose() and connkeep() when changing the "close
state" for a connection. These two macros take a string argument with an
explanation, and debug builds of curl will include that in the debug
output. Helps tracking connection re-use/close issues.
Commit 517b06d657 (in 7.36.0) that brought the CREDSPERREQUEST flag
only set it for HTTPS, making HTTP less good at doing connection re-use
than it should be. Now set it for HTTP as well.
Simple test case

The variable wasn't assigned at all until step3 which would lead to a

Bug: http://curl.haxx.se/mail/lib-2014-04/0203.html
In commit 0b3750b5c2 (released in 7.36.0) we fixed a timeout issue
but instead broke the timings.
To fix this, I introduce a new timestamp to use for the timeouts and
restored the previous timestamp and timestamp position so that the old
timer functionality is restored.
In addition to that, that change also broke connection timeouts for when
more than one connect was used (as it would then count the total time
from the first connect and not for the most recent one). Now
Curl_timeleft() has been modified so that it checks against different
start times depending on which timeout it checks.
Test 1303 is updated accordingly.

Whilst the qop directive isn't required to be present in a client's
response, as servers should assume a qop of "auth" if it isn't
specified, some may return authentication failure if it is missing.
To cater for the automatic generation of the new Visual Studio project
files, moved the lib file list into a separated variable so that lib

-p takes a list of Mozilla trust purposes and levels for certificates to
include in output. Takes the form of a comma separated list of
purposes, a colon, and a comma separated list of levels.
Now nghttp2_submit_request returns assigned stream ID, we don't have
to check stream ID using before_stream_send_callback. The
adjust_priority_callback was removed.
Depending on compiler line 3505 could generate the following warning or
error:
* warning: ISO C90 forbids mixed declarations and code
* A declaration cannot appear after an executable statement in a block
* error C2275: 'size_t' : illegal use of this type as an expression
As there's a default connection timeout and this wrongly used the
connection timeout during a transfer after the connection is completed,
this function would trigger timeouts during transfers erroneously.

If the precision is indeed shorter than the string, don't strlen() to
find the end because that's not how the precision operator works.
I also added a unit test for curl_msnprintf to make sure this works and
that the fix doesn't a few other basic use cases. I found a POSIX
compliance problem that I marked TODO in the unit test, and I figure we
need to add more tests in the future.

Commit 07b66cbfa4 unfortunately broke native NTLM message support in
compilers, such as VC6, VC7 and others, that don't support long long
type declarations. This commit fixes VC6 and VC7 as they support the
__int64 extension, however, we should consider an additional fix for
other compilers that don't support this.
set.infilesize in this case was modified in several places, which could
lead to repeated requests using the same handle to get unintendent/wrong
consequences based on what the previous request did!
This makes the findprotocol() function work as intended so that libcurl
can properly be restricted to not support HTTP while still supporting
HTTPS - since the HTTPS handler previously set both the HTTP and HTTPS
bits in the protocol field.
This fixes --proto and --proto-redir for most SSL protocols.
This is done by adding a few new convenience defines that groups HTTP
and HTTPS, FTP and FTPS etc that should then be used when the code wants
to check for both protocols at once. PROTO_FAMILY_[protocol] style.

As this makes curl_global_init_mem() behave the same way as
curl_global_init() already does in that aspect - the same number of
curl_global_cleanup() calls is then required to again decrease the
counter and then eventually do the cleanup.

ufds might not be allocated in case nfds overflows to zero while
extra_nfds is still non-zero. udfs is then accessed within the
extra_nfds-based for loop.
Should a command return untagged responses that contained no data then
the imap_matchresp() function would not detect them as valid responses,
as it wasn't taking the CRLF characters into account at the end of each
line.
Given that we presently support "auth" and not "auth-int" or "auth-conf"
for native challenge-response messages, added client side validation of
the quality-of-protection options from the server's challenge message.
To avoid urldata.h being included from the header file or that the
source file has the correct include order as highlighted by one of
the auto builds recently.
When CURL_DISABLE_CRYPTO_AUTH is defined the DIGEST-MD5 code should not
be included, regardless of whether USE__WINDOWS_SSPI is defined or not.
This is indicated by the definition of USE_HTTP_NEGOTIATE and USE_NTLM
in curl_setup.h.
Updated the docs to clarify and the code accordingly, with test 1528 to
verify:
When CURLHEADER_SEPARATE is set and libcurl is asked to send a request
to a proxy but it isn't CONNECT, then _both_ header lists
(CURLOPT_HTTPHEADER and CURLOPT_PROXYHEADER) will be used since the
single request is then made for both the proxy and the server.
When doing passive FTP, the multi state function needs to extract and

In addition to commit fe260b75e7 fixed the same issue for RFC-821 based
SMTP servers and allow the credientials to be given to curl even though
they are not used with the server.

authentication would cause curl to display "No known authentication

The debug messages printed inside PolarSSL always seems to end with a
newline. So 'infof()' should not add one. Besides the trace 'line'
should be 'const'.
Because of the socket is unblocking, PolarSSL does need call to getsock to
get the action to perform in multi environment.
In some cases, it might happen we have not received yet all data to perform
the handshake. ssh_handshake returns POLARSSL_ERR_NET_WANT_READ, the state
is updated but because of the getsock has not the proper #define macro to,
the library never prevents to select socket for input thus the socket will
never be awaken when last data is available. Thus it leads to timeout.
API has changed since version 1.3. A compatibility header has been created
to ensure forward compatibility for code using old API:
* x509 certificate structure has been renamed to from x509_cert to
x509_crt
* new dedicated setter for RSA certificates ssl_set_own_cert_rsa,
ssl_set_own_cert is for generic keys
* ssl_default_ciphersuites has been replaced by function
ssl_list_ciphersuites()
This patch drops the use of the compatibly header.
Rename x509_cert to x509_crt and add "compat-1.2.h"
include.
This would still need some more thorough conversion
in order to drop "compat-1.2.h" include.
Port number zero is perfectly allowed to connect to. I moved to storing
the remote port number in an int so that -1 means undefined and 0-65535
can be used for legitimate port numbers.
Setting the TIMER_STARTSINGLE timestamp first in CONNECT has the
drawback that for actions that go back to the CONNECT state, the time
stamp is reset and for the multi_socket API there's no corresponding
Curl_expire() then so the timeout logic gets wrong!

For HTTP/2, we may read up everything including responde body with
header fields in Curl_http_readwrite_headers. If no content-length is
provided, curl waits for the connection close, which we emulate it
using conn->proto.httpc.closed = TRUE. The thing is if we read
everything, then http2_recv won't be called and we cannot signal the
HTTP/2 stream has closed. As a workaround, we return nonzero from
data_pending to call http2_recv.
Original commit message was:
Don't omit CN verification in SChannel when an IP address is used.
Side-effect of this change:
SChannel and CryptoAPI do not support the iPAddress subjectAltName
according to RFC 2818. If present, SChannel will first compare the
IP address to the dNSName subjectAltNames and then fallback to the
most specific Common Name in the Subject field of the certificate.
This means that after this change curl will not connect to SSL/TLS
hosts as long as the IP address is not specified in the SAN or CN
of the server certificate or the verifyhost option is disabled.
