If a proxy offers several Authentication schemes where NTLM and
Negotiate are offered by the proxy and you tell libcurl not to use the
Negotiate scheme then the request never returns when the proxy answers
with its HTTP 407 reply.
It is reproducible by the following steps:
- Use a proxy that offers NTLM and Negotiate ( CURLOPT_PROXY and
CURLOPT_PROXYPORT )
- Tell libcurl NOT to use Negotiate CURL_EASY_SETOPT(CURLOPT_PROXYAUTH,
CURLAUTH_BASIC | CURLAUTH_DIGEST | CURLAUTH_NTLM )
- Start the request
The call to CURL_EASY_PERFORM never returns. If you switch on debug
logging you can see that libcurl issues a new request As soon as it
received the 407 reply. Instead it should return and set the response
code to 407.

Move calling of ERR_remove_state(0) a.k.a ERR_remove_thread_state(NULL)
from Curl_ossl_close_all() to Curl_ossl_cleanup().
In this way ERR_remove_state(0) is now only called in libcurl by
curl_global_cleanup(). Previously it would get called by functions
curl_easy_cleanup(), curl_multi_cleanup and potentially each time a
connection was removed from a connection cache leading to premature
destruction of OpenSSL's thread local state hash.
Multi-threaded apps using OpenSSL enabled libcurl should still call
function ERR_remove_state(0) or ERR_remove_thread_state(NULL) at the
very end end of threads that do not call curl_global_cleanup().
Now called 'use_ssl' instead, which better matches the current CURLOPT
name and since the option is used for all pingpong protocols (at least)
it makes sense to not use 'ftp' in the name.
Use gnutls_priority_set_direct() instead of gnutls_protocol_set_priority().
Remove the gnutls_certificate_type_set_priority() use since x509 is the
default certificate type anyway.

This extends the fix from commit d7934b8bd4
When the multi state is changed within the multi_runsingle from DOING to
DO_MORE, we didn't immediately start the FTP state machine again. That
then left the FTP state in FTP_STOP. When curl_multi_fdset() was
subsequently called, the ftp_domore_getsock() function would return the
wrong fd info.
Reported by: Gokhan Sengun
After a PORT has been issued, and the multi handle would switch to the
CURLM_STATE_DO_MORE state (which is unique for FTP), libcurl would
return the wrong fdset to wait for when curl_multi_fdset() is
called. The code would blindly assume that it was waiting for a connect
of the second connection, while that isn't true immediately after the
PORT command.
Also, the function multi.c:domore_getsock() was highly FTP-centric and
therefore ugly to keep in protocol-agnostic code. I solved this problem
by introducing a new function pointer in the Curl_handler struct called
domore_getsock() which is only called during the DOMORE state for
protocols that set that pointer.
The new ftp.c:ftp_domore_getsock() function now returns fdset info about
the control connection's command/response handling while such a state is
in use, and goes over to waiting for a writable second connection first
once the commands are done.
The original problem could be seen by running test 525 and checking the
time stamps in the FTP server log. I can verify that this fix at least
fixes this problem.

The default lowat level for gnutls-2.12* is set to zero to avoid
unnecessary system calls and the gnutls_transport_set_lowat function has
been totally removed in >=gnutls-3 which causes build failures.
Therefore, the function shouldn't be used except for versions that
require it, <gnutls-2.12.0.
Previously the bit was set before the connection was found working so if
it would first fail to an ipv6 address and then connect fine to a IPv4
address the variable would still be TRUE.

When doing a multipart formpost with a read callback, and that callback
returns CURL_READFUNC_ABORT, that return code must be properly
propagated back and handled accordingly. Previously it would be handled
as a zero byte read which would cause a hang!
Added test case 587 to verify. It uses the lib554.c source code with a
small ifdef.

Save the errno value immediately after a connect() failure so that it

Set ACK timeout to 5 seconds.
If we are waiting for block X and receive block Y that is the expected one, we
should send ACK and increase X (which is already implemented). Otherwise drop
the packet and don't increase retry counter.
Prevent modification of easy handle being added with curl_multi_add_handle()
unless this function actually suceeds.
Run Curl_posttransfer() to allow restoring of SIGPIPE handler when
Curl_connect() fails early in multi_runsingle().
It makes much nicer and less convuluted code everywhere if this struct
member is always present even when libcurl is built without SSL support.
This reverts parts of commit 15e3e45170
Modified smtp_endofresp() to detect NTLM from the server specified list
of supported authentication mechanisms.
Modified smtp_authenticate() to start the sending of the NTLM data.
Added smtp_auth_ntlm_type1_message() which creates a NTLM type-1
message. This function is used by authenticate() to start the sending
of data and by smtp_state_auth_ntlm_resp() when the AUTH command
doesn't contain the type-1 message as part of the initial response.
This lack of initial response can happen if an OOM error occurs or the
type-1 message is longer than 504 characters. As the main AUTH command
is limited to 512 character the data has to be transmitted in two
parts; one containing the AUTH NTLM and the second containing the
type-1 message.
Added smtp_state_auth_ntlm_type2msg_resp() which handles the incoming
type-2 message and sends an outgoing type-3 message. This type-2
message is sent by the server in response to our type-1 message.
Modified smtp_state_auth_resp() to handle the response to: the AUTH
NTLM without the initial response and the type-2 response.
Modified smtp_disconnect() to cleanup the NTLM SSPI stack.
Added the output message length as a parameter to both
Curl_ntlm_create_type1_message() and Curl_ntlm_create_type3_message()
for use by future functions that require it.
Updated curl_ntlm.c to cater for the extra parameter on these two
functions.
Changed the name of variable l, in several functions, which represents
the length of strings being sent to the server, to len which is more
meaningful and consistent with other code in smtp.c and elsewhere.
Reworked smtp_authenticate() to be simpler and easier to follow.
Variables and now initialised in their definitions and if no username
and password are specified the function sets the state to SMTP_STOP and
returns immediately, rather than being part of a huge if statement.
Don't even declare the struct members for disabled features
Introducing the CURLSHE_NOT_BUILT_IN return code for the share interface
when trying to set a sharing option that has been disabled (or not
enabled) in the library.
When the progress function returns to cancel the request, we must mark
the connection to get closed and it must do to the DONE state.
do_init() must be called as early as possible so that state variables
for new connections are reset early. We could otherwise see that the old
values were still there when a connection was to be disconnected very
early and it would make it behave wrongly.

The size of the email can now be set via CURLOPT_INFILESIZE. This
allows the email to be rejected by the server, if supported, and the
maximum size has been configured on the server.
Removed the code that striped off the domain name when Curl_gethostname
returned the fully qualified domain name as the function has been
updated to return the un-qualified host name.
Replaced the use of HOSTNAME_MAX as the size of the buffer in the call
to Curl_gethostname with sizeof(host) as this is safer should the buffer
size ever be changed.
Allow (*curl_write_callback) write callbacks to return
CURL_WRITEFUNC_OUT_OF_MEMORY to properly indicate libcurl of OOM conditions
inside the callback itself.
If a socket is larger than FD_SETSIZE, avoid using FD_SET() on the
platforms where this is possible.

To avoid that the progress meter headers get output between each
transfer, make sure the bits gets kept when (re-)inited.
Reported by: Christopher Stone
I think curl should ignore this case and smtp.c should test for this.
Since RFC-2821 seems to allow a "null reverse-path". Ref. "MAIL
FROM:<>" in section 3.7, page 25.
Fixed Curl_gethostname() so that it always returns the un-qualified
machine name rather than being dependent on the socket provider.
Note: The return of getenv("CURL_GETHOSTNAME") is also parsed in case
the developer / test harness provided a fully qualified domain name as
it's value as well.
With this fix, it should work for PolarSSL-1.0.0 (and SVN-1091 trunk)
and retain compatibility with earlier versions. (Tested with 0.14.1)
PolarSSL still doesn't play nicely with curl's CA bundle (we discussed
this before) but I was at least able to retrieve the
https://www.gmail.com/ login page using a modified ca-certificates.crt
file with all 3 versions of PolarSSL.
Renamed the variable from 'proto' to 'level' simply because it is not
protocol you set but level and that is the name of the argument used in
man pages and the POSIX documentation of the setsockopt function.
This workarounds old libssh2 versions not properly initializing
some ssh session variables, which would trigger memory debuggers
warnings on memory being used without having been initialized.
The current version of speedcheck.c may disable timeout by setting zero
to Curl_expire. Which is fine using the curl_multi_perform, because it
recheck all timeout internals, but when using custom event poller (like
hiperfifo.c) it may keep stalle connection forever.
