winsock.h pulls in a lot of defines and dependencies that are not
required and partially unwanted in winpr's core (for parts that are not
related to network). In order to get rid of this dependency and have an
independent defines for extended winpr functions the WINPR_FD_* defines
are used internally (and for exposed functions). Where required, like in
WSAEventSelect, the FD_* is mapped to WINPR_FD_*.
Allows the WinPR HANDLE functions WaitForSingleObject and
WaitForMultipleObjects to signal in case of write events.
This is used by CreateFileDescriptor and SetEventFileDescriptor,
which got an API change accomodating for this new feature.
This patch contains:
* checks for malloc return value + treat callers;
* modified malloc() + ZeroMemory() to calloc();
* misc fixes of micro errors seen during the code audit:
** some invalid checks in gcc.c, also there were some possible
integer overflow. This is interesting because at the end the data are parsed
and freed directly, so it's a vulnerability in some kind of dead code (at least
useless);
** fixed usage of GetComputerNameExA with just one call, when 2 were used
in misc places. According to MSDN GetComputerNameA() is supposed to return
an error when called with NULL;
** there were a bug in the command line parsing of shadow;
** in freerdp_dynamic_channel_collection_add() the size of array was multiplied
by 4 instead of 2 on resize
- HRESULT was unsigned which means that until now all usages of the
SUCCEDED(hr) and FAILED(hr) macros never detected any errors
- Also fixed the (unused) SCODE typedef
- Added new ctest TestTypes
Exposing lzcnt in crt.h might causes compiler errors (redefinition) with
recent versions of gcc (>=4.9) when winpr is included in other projects.
As lzcnt isn't part of crt according to MSDN and also shouldn't be
exported by default it was moved to intrin.h.
The related test was also moved to the top level directory of winpr.
With this patch the default for the console logger
changes to writing to stdout for TRACE, DEBUG and INFO
messages and stderr for WARNING, ERROR and FATAL messages.
Change the return type of Stream_Ensure*Capacity from void to BOOL to be
able to detect realloc problems easily. Otherwise the only way to detect
this was to check if the capacity after the call was >= the required
size.
In case Stream_Ensure*Capacity fails the old memory is still available
and need to freed outside.
This commit also adds checks to most calls of Stream_Ensure*Capacity to
check if the call was successful.
+ add: COMMAND_LINE_IGN_UNKNOWN_KEYWORD flag for CommandLineParseArgumentsA to ignory unknown keys without fail
+ add: lot of WLog_DBG() in drdynvc, add function names in existing
* change: error text in rdpsnd OSS
* fix: dev in rdpsnd does not work
* fix/change: audio-dev renamed to dev and now work in audin
* fix dynamic channels now work again
WTSStartRemoteControlSession doesn't allow to specify additional flags
therefore add a new extended version WTSStartRemoteControlSessionEx
with an additional "flags" parameter.
The following flags are defined:
REMOTECONTROL_FLAG_DISABLE_KEYBOARD - disable keyboard input
REMOTECONTROL_FLAG_DISABLE_MOUSE - disable mouse input
REMOTECONTROL_FLAG_DISABLE_INPUT - disable input (keyboard and mouse)
- added missing definitions for session change notification
- extended wtsapi to allow remote logon and logoff against the wtsapi (this allows remote wtsapi usage)
freerdp/winpr had the following issues:
* The non reentrant SSL_library_init() was called concurrently (crash)
* Missing code/api to set the eventually required OpenSSL static and dynamic locking callbacks
* Missing code/api to free the application-global or thread-local OpenSSL data and tables
This commit creates two new winpr functions:
BOOL winpr_InitializeSSL(DWORD flags):
Use the flag WINPR_SSL_INIT_ALREADY_INITIALIZED if you want to tell winpr that
your application has already initialized OpenSSL.
If required use the flag WINPR_SSL_INIT_ENABLE_LOCKING to tell winpr that it
should set the OpenSSL static and dynamic locking callbacks.
Otherwise just call it with the flag WINPR_SSL_INIT_DEFAULT.
The recommended way is that your application calls this function once before
any threads are created. However, in order to support lazy OpenSSL library
initialization winpr_InitializeSSL() can also safely be called multiple times
and concurrently because it uses the new InitOnceExecuteOnce() function to
guarantee that the initialization is only performed successfully once during
the life time of the calling process.
BOOL winpr_CleanupSSL(DWORD flags):
If you create a thread that uses SSL you should call this function before the
thread returns using the flag WINPR_SSL_CLEANUP_THREAD in order to clean up
the thread-local OpenSSL data and tables.
Call the function with the flag WINPR_SSL_CLEANUP_GLOBAL before terminating
your application.
Note: This commit only replaced the current occurences of the
SSL_load_error_strings(); SSL_library_init(); pairs in the freerdp source
with winpr_InitializeSSL(). None of the server or client applications has been
changed according to the recommended usage described above (TBDL).
