GCC 4.6.3 on travis complains:
smb.c: In function ‘get_posix_time’:
smb.c:725:13: error: declaration of ‘time’ shadows a global declaration
[-Werror=shadow]
Fix this by renaming the variable.

Closes #1643

Add a new type of callback to Curl_handler which performs checks on
the connection. Alter RTSP so that it uses this callback to do its
own check on connection health.

Feature defines are normally checked with #ifdef instead of #if in the rest of
the codebase. Additionally, some compilers warn when a macro is implicitly
evaluated to 0 because it is not defined, which was the case here.

This is done for all functions of the form Curl_read[136][624]_[lb]e.
|
|
Not all reply messages were properly checked for their lengths, which
made it possible to access uninitialized memory (but this does not lead
to out of boundary accesses).
Closes #1052

CVE-2015-3237
Detected by Coverity. CID 1299430.
Bug: http://curl.haxx.se/docs/adv_20150617B.html
|
|
This header file must be included after all header files except
memdebug.h, as it does similar memory function redefinitions and can be
similarly affected by conflicting definitions in system or dependent
library headers.

Since we just started make use of free(NULL) in order to simplify code,
this change takes it a step further and:
- converts lots of Curl_safefree() calls to good old free()
- makes Curl_safefree() not check the pointer before free()
The (new) rule of thumb is: if you really want a function call that
frees a pointer and then assigns it to NULL, then use Curl_safefree().
But we will prefer just using free() from now on.

Use the connection's upload buffer instead of allocating our own send
buffer.
|
|
|
|
Renamed smb_setup() to smb_setup_connection() to follow more widely
used function naming.
|
|
... as it never copies the trailing zero anyway and always just the four
bytes so let's not mislead anyone into thinking it is actually treated
as a string.

smb.c:320: warning C6297: Arithmetic overflow: 32-bit value is shifted,
then cast to 64-bit value. Result may not be an expected
value
|
|
Rather than testing against _WIN32 use the preferred HAVE_PROCESS_H
pre-processor define when including process.h.
|
|
There is no need to set the 'state' and 'result' member variables to
SMB_REQUESTING (0) and CURLE_OK (0) after the allocation via calloc()
as calloc() initialises the contents to zero.
|
|
|
|
For debugging purposes, and as per other protocols within curl, added
state change functions rather than changing the states directly.
|
|
This fixes compilation issues with compilers that don't support 64-bit
integers through long long or __int64.

As Windows based autoconf builds don't yet define USE_WIN32_CRYPTO
either explicitly through --enable-win32-cypto or automatically on
_WIN32 based platforms, subsequent builds broke with the following
error message:
"Can't compile NTLM support without a crypto library."
|
|
Build SMB/CIFS protocol support when SSPI is enabled.
|
|
Fixed an issue with the message size calculation where the raw bytes
from the buffer were interpreted as signed values rather than unsigned
values.

On some platforms curl would crash if no credentials were used. As such
added detection of such a use case to prevent this from happening.

Initial implementation of the SMB/CIFS protocol.

Added the SMB and SMBS handler interface structures and associated
functions required for SMB/CIFS operation.
