Shadow server crash with rdp8.0 with gfx enabled.
Root Cause: rdp8.0 is not support in shadow gfx and rdpgfx_caps_advertise returns an error. However setChannelError crashs because context->errorDescription is NULL
1. Fix shadow gfx to handle rdp8.0
2. Initialize context->errorDescription for server side new-context
1. Fix order of gfx reset and new-surface. Windows10 client will show black screen with this issue(FreeRDP itself is dramatically immune to this issue)
2. Handle RDPGFX_QOE_FRAME_ACKNOWLEDGE_PDU for FPS control
1. Fix stream leak in rdpgfx
2. Make src data const in zgfx. Harden zgfx to be independent to byte order
3. Fix written bytes return value in channel write
4. Add check for return value in shadow_client.c
5. Add gfx callback to send surface command with frame marker pdu.
6. Check remain length for recv subroutine
7. Fix compile errors
libwinpr-tools is a replacement for winpr-makecert-tool.a. Currently
it's basically the same as winpr-makecert-tool.a but in future
functionality that doesn't fit directly in winpr will be added here.
Add all missing dependencies found with --no-undefined. Since
dependencies aren't exported anymore (if not required) it is no necessary
to explicitly list all required libraries.
If a target is linked against libraries with cmake
(target_link_libraries) and the libraries are not marked as PRIVATE
they are "exported" and in case a other target is linked against this
target it is also linked against *all* (not private) libraries.
Without declaring private libraries PRIVATE a lot of over linking
(linking against unneeded libraries) was done.
- Added missing ConvertFromUnicode checks
- If ConvertToUnicode allocates memory, guarantee the null termination
similar to ConvertFromUnicode's implementation
- Fixed some TestUnicodeConversion.c CTest return values
- Added some CTests for ConvertFromUnicode and ConvertToUnicode
- Misc code and protocol hardening fixes in the surrounding code regions
that have been touched
Add freerdp-shadow-subsystem to 'libs' in order to avoid undefined
reference to shadow_subsystem_set_entry_builtin at runtime.
Remove cyclic dependency on itself.
When nothing is declared, only export symbols defined
with WINPR_API or FREERDP_API defined.
Override this setting if BUILD_TESTING to allow tests
access to internal functions usually not exposed.
Commit 60ae27b0 decoupled subsystem implementations and shadow framework
core by moving subsystem specific code right into freerdp-shadow-cli.
This, however, doesn't allow applications that would like to link
libfreerdp-shadow, in order to embed RDP shadow server, to reuse also
the subsystem module.
3rd party developers now have to either provide their own subsystem code
(copied from FreeRDP sources or written from scratch) or be limited to
usaging freerdp-shadow-cli executable, which doesn't expose all
functions of the shadow server library (e.g. enumeration of available
monitors).
This change moves the shadow subsystem out of the executable into new
freerdp-shadow-subsystem library, which freerdp-shadow-cli and
potentially other applications can link to.
Certificates can now be accepted temporarily.
The callbacks for certificate validation have been
modified to extend the information presented to the user.
