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.
Bug: http://curl.haxx.se/mail/lib-2011-10/0006.html
Reported by: Vladimir Grishchenko
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.
Slight rewording of the CURLOPT_URL SMTP sub-section.
Corrected the incorrect use of hyphens on the three uses of
"zero-terminated" with "zero terminated" to match the rest of the
document.
Corrected the use of an out of place hyphen in CURLOPT_NOPROXY section.
Maximum amount of data a header callback is supposed to get in
a single call from libcurl is limited by the lowest value of
CURL_MAX_WRITE_SIZE and CURL_MAX_HTTP_HEADER.
When using Sun C compiler the preprocessor somehow inserts an extra space
in front of replaced symbol, breaking CURL_CHECK_DEF macro. To workaround
this, macro CURL_CHECK_DEF now ignores all leading whitespace in front of
symbol substitution result.
