In order to avoid for example the pingpong protocols to issue STARTTLS
(or equivalent) even though there's no SSL support built-in.

As the change in 5f0ae7a0626cbe709 added a precaution against negative
file sizes that for some reason managed to get returned, this change now
introduces the same check at the second place in the code where the file
size from the libssh2 stat call is used.
This check might not be suitable for a 32 bit curl_off_t, but libssh2.h
assumes long long to work and to be 64 bit so I believe such a small
curl_off_t will be very unlikely to occur in the wild.

Renamed SDK_* to NDK_*; made NDK_* defines overwriteable from
environment; removed now obsolete YACC macro;
moved some curl_config.h defines to IPv6 section since they
are only needed when IPv6 is enabled - this makes libcurl compile
with older NDKs too which were not IPv6-aware.

We forgot to release the buffer passed to gss_init_sec_context.
The previous logic was difficult to read as we were reusing the same
variable (gssbuf) for both input buffer and output buffer. Splitted the
logic in 2 variables to better underline who needs to be released.
Also made the code break at 80 lines.

kr5_auth missed a final 'return' statement. This is not an error in
gcc but can lead to potential bugs.
|
|
This fixes a memory leak related to the GSS-API code.
Added a krb5_init and krb5_end functions. Also removed a work-around
the lack of proper initialization of the GSS-API context.

It was pointed out that the special case libcurl did for 416 was
incorrect and wrong. 416 is not really different to other errors so the
response body must be handled like for other errors/http responses.

It is still not clarified exactly why this happens, but libssh2
sometimes report a negative file size for the remote SFTP file and that
deeply confuses libcurl (or crashes it) so this precaution is added to
avoid badness.

Remove a leak seen on Kerberos/MIT (gss_OID is copied internally and
we were leaking it). Now we just pass NULL as advised in RFC2744.
|tmp| was never set back to buf->data.
Cleaned up Curl_sec_end to take into account failure in Curl_sec_login
(where conn->mech would be NULL but not conn->app_data or
conn->in_buffer->data).
|
|
The current implementation would make us send wrong data on a closed
socket. We don't buffer our data so the method can be safely removed.
|
|
Following a change in the way socket handler are registered, the custom
recv and send method were conditionaly registered.
We need to register them everytime to handle the ftp security
extensions.
Re-added the clear text handling in sec_recv.
|
|
Curl_sec_login was returning the opposite result that the code in ftp.c
was expecting. Simplified the return code (using a CURLcode) so to see
more clearly what is going on.
|
|
They are not automatically added and make the output of the verbose
mode a lot more readable.

|
My use of va_args was completely wrong. Fixed the usage so that
we send the right commands!

According to RFC3986 section 2.3 the letters -, ., _ and ~ should not be

The functions Curl_disconnect() and Curl_done() are both used within the
scope of a single request so they cannot be allowed to use
Curl_expire(... 0) to kill all timeouts as there are some timeouts that
are set before a request that are supposed to remain until the request
is done.
The timeouts are now instead cleared at curl_easy_cleanup() and when the
multi state machine changes a handle to the complete state.
|
|
With the latest changes to fix the timeout handling with multi interface
we lost the timeout error messages. This patch brings them back.
|
|
The date format in RFC822 allows that the seconds part of HH:MM:SS is
left out, but this function didn't allow it. This change also includes a
modified test case that makes sure that this now works.

Just made sure that the good old curl indentation style is used all over
this file.

tftpd-hpa has a bug where it will send an incorrect ack when the block
counter wraps and tftp options have been sent. Work around that by
accepting an ack for 65535 when we're expecting one for 0.

This reverts commit fbb38de415b7bb7d743e53a7b4b887ffb12b3e5b.
|

And also removed the FIXME where memory was zeroed just before freed,
and some other minor whitespace changes.

- |fd| is now a curl_socket_t and |len| a size_t to avoid conversions.
- Added 2 FIXMEs about the 2 unsigned -> signed conversions.
- Included 2 minor changes to Curl_sec_end.
|
|
- Renamed the method to sec_send now that we
renamed sec_send to do_sec_send.
- Some more variable renaming.
|
|
- Renamed the function to sec_recv.
- Renamed the parameters and variable to match the rest of the code.
|
|
- Use an early return as it makes the code more readable.
- Added a FIXME about a conversion.
|
|
- Renamed it to do_sec_send as it is the function doing the actual
transfer.
- Do not return any values as no one was checking it and it never
reported a failure (added a FIXME about checking for errors).
- Renamed the variables to make their use more specific.
- Removed some casts (int -> curl_socket_t, ...)
- Avoid doing the htnl <-> nthl twice by caching the 2 results.
|
|
- Renamed the variables name to better match their intend.
- Unified the |decoded_len| checks.
- Added some FIXMEs to flag some improvement that did not go in this
change.
|
|
- Removed sec_prot_internal as it is now inlined in the function (this removed
a redundant check).
- Changed the prototype to return an error code.
- Updated the method to use the new ftp_send_command function.
- Added a level_to_char helper method to avoid relying on the compiler's
bound checks. This default to the maximum security we have in case of a
wrong input.

that better reflect its intent.
Introduced a helper method ftp_send_command that synchronously send
an FTP query.
|
|
|
|
Tighten the type of the |data| parameter to avoid a cast. Also made
it const as we should not modify it.
Added a DEBUGASSERT on the size to be written while changing it.
|
|
While doing so, renamed it to socket_write to better match its
function.
|
|
To do so, made block_read call Curl_read_plain instead of read.
While changing them renamed block_read to socket_read and sec_get_data
to read_data to better match their function.
Also fixed a potential memory leak in block_read.

Obviously, browsers ignore a colon without a following port number. Both
Firefox and Chrome just removes the colon for such URLs. This change
does not remove the colon for URLs sent over a HTTP proxy, so we should
consider doing that change as well.

curl_easy_duphandle() was not properly duping the ares channel. The
ares_dup() function was introduced in c-ares 1.6.0 so by starting to use
this function we also raise the bar and require c-ares >= 1.6.0
(released Dec 9, 2008) for such builds.

When it returns 0 it means no timeout. Only a negative value means that
we're out of time.
|
|
If built without HTTP or proxy support it would cause a compiler warning
due to the unused variable. I moved the declaration of it into the only
scope it is used.
