* man pages are only build/installed if WITH_MANPAGES is enabled
* create a new cmake function install_freerdp_man to unified install man
pages
* install all man pages using the new function
* update the nightly packages accordingly
When certificates with more than 2048 bits were generated and written to
file the read function used a erroneous calculated length causing the
used buffer to overflow.
Currently it is not possible to cleanly install multiple major version
of FreeRDP concurrently as some of the development libraries (.so files)
files can conflict.
This change renames all libraries to include the major version number in
the library name to fix this limitation.
The list of changed libraries:
libwinpr-tools.so -> libwinpr-tools2.so
libwinpr.so -> libwinpr2.so
libfreerdp.so -> libfreerdp2.so
libfreerdp-client.so -> libfreerdp-client2.so
libfreerdp-shadow.so -> libfreerdp-shadow2.so
libfreerdp-server.so -> libfreerdp-server2.so
libfreerdp-shadow-subsystem.so -> libfreerdp-shadow-subsystem2.so
libuwac.so -> libuwac0.so
As the library names have changed, projects that use FreeRDP will need to
update their dependencies. -
If pkg-config or cmake find modules are used, reconfiguration might be
sufficient.

SSL functions like OpenSSL_add_all_digests should be invoked at very beginning as they are not MT safe.

- fixed invalid, missing or additional arguments
- removed all type casts from arguments
- added missing (void*) typecasts for %p arguments
- use inttypes defines where appropriate
Undefined preprocessor macro in wtypes.h produces:
warning: "__ILP64__" is not defined [-Wundef]
This causes unnecessary hassle to people who compile their FreeRDP-based
applications with -Werror.
* fix spelling errors
* move man page from section 1 to section 7
* fix the man page header to match the actual section
* adapt the packages for wlog.7

- winpr_HMAC_New() now just returnes the opaque WINPR_HMAC_CTX* pointer
which has to be passed to winpr_HMAC_Init() for (re)initialization
and since winpr_HMAC_Final() no more frees the context you always have to
use the new function winpr_HMAC_Free() once winpr_HMAC_New() has succeded
- winpr_Digest_New() now just returns the opaque WINPR_DIGEST_CTX* pointer
which has to be passed to winpr_Digest_Init() for (re)initialization
and since winpr_Digest_Final() no more frees the context you always have to
use the new function winpr_Digest_Free() once winpr_Digest_New() has succeded
iOS does not support Thread Local Storage.
Disabling it for now until a solution is found.
Print a compiler warning informing developers about this issue.
Global static variables do not work, if more than one instance
of an RDP client is running in the same process space.
Removed the varaibles where possible and replaced them with
thread local storage where necessary.
The lpnSize parameter for GetComputerNameEx specifies the total
size of the buffer (in characters).
However, the current code calculated the amount of bytes.
Since only GetComputerNameExA was used and because sizeof(CHAR) == 1
the result was correct but the math was wrong.

Depending on the windows target version (_WIN32_WINNT), the used
SDK and the build configuration the linker will see multiple
libraries exporting the same symbols.
To prevent ugly hacks (e.g. modifying cmake's default system
libraries or fragile library linking order chains) we prefix
these functions with "winpr_" and create corresponding defines
to keep the current api names.
On input, the lpnSize [in, out] parameter for GetComputerNameEx()
specifies the total size of the buffer (in characters).
Several functions in ntlm.c were off by one which caused ntlm to fail
if the netbios hostname's strlen was exactly MAX_COMPUTERNAME_LENGTH.
PathMakePathA:
- This function had an endless loop if no native delimiter was in the string
- Use SHCreateDirectoryExA on Windows
- Replaced old code with a new implementation
TestWLog:
- Windows has no "/tmp" by default
- Use GetKnownPath(KNOWN_PATH_TEMP) for the WLog "outputfilepath"
- Use correct SetLastError values in GetModuleFileName
- Fix wrong return codes in GetModuleFileName
- Build the TestLibraryA/TestLibraryB libraries always shared and
put them in the test output directory
- TestLibraryGetModuleFileName always returned success
- Improve TestLibraryGetModuleFileName to also check last error values
and insufficient buffer sizes
- Change TestLibraryGetProcAddress and TestLibraryLoadLibrary to load
the TestLibrary from the test executable's directory
TestNtCreateFile, TestPipeCreateNamedPipeOverlapped
- These tests are currently only expected to succeed on _WIN32
- Also reflect the reverse meaning of this fact in the return values
TestSynchWaitableTimer, TestSynchWaitableTimerAPC:
- These tests are currently expected to fail on __APPLE__
- Also reflect the reverse meaning of this fact in the return values
This logic makes sure that we don't forget to fix the tests if the
corresponding WinPR implementations are fixed.
TestLibrary:
- TestLibraryA and TestLibraryB must always get built as shared libraries
Let the compiler know that we're comparing a volatile value.
Otherwise the compiler might nuke the comparison operation
and produce code that will spin endlessly.
The SYNCHRONIZATION_BARRIER_FLAGS_SPIN_ONLY flag caused this test
to run extremely long if the system has very few processors.
Although this is expected (thread starvation) this will cause a
intolerably long execution time for automated tests.
Changed the number of threads to be calculated dyamically based
on the number of processors.
Also do proper cleanup to prevent memory leaks.
The current experimental/incomplete WinPR timer queue implementation
has several race conditions.
This commit fixes a segfault caused by not unklinking freed timers
from the timer queue timers list.
pool:
- the winpr implementation fallback was not used on older windows editions
- drop useless and conflicting TP_CALLBACK_ENVIRON_V3
- fix race conditions by using use proper one-time initialization
- on win32 WinPR tried to load several pool/callback_environment functions
from kernel32.dll but since these are defined as inline functions in the
windows headers, no windows edition has ever exported them in any dll.
- removed callback_environment.c and added corresponding static inline
function to pool.h
- fix segfault in TestPoolWork: CloseThreadpoolWork() must not be called
if there is a cleanup group associated with the work object since calling
CloseThreadpoolCleanupGroupMember() already releases the work object
sync:
- The windows headers incorrectly define InitializeCriticalEx support if
_WIN32_WINNT >= 0x0403 instead of >= 0x0600 (Vista)
- created a compatible define to deal with this issue
On some operating systems sched_yield is a stub returning returning -1.
In that case use usleep which should at least trigger a context switch
if any thread is waiting.
Half of the tests expects strings in little endian byte order, half of
the tests expects byte order based on a current architecture, so it
obviously can't work on big endian machines. Wide char strings use
always little endian encoding since commit f722dc5. Use only strings
in little endian to make the tests endian-independent.
Since the current winpr implementation for overlapped operations is
incomplete and buggy, all affected functions will now fail if they are
called with a set FILE_FLAG_OVERLAPPED flag or a non-null pointer to
a OVERLAPPED structure.
winpr/nt:
- use proper one-time initialization on win32
- fix TestNtCreateFile
- fix broken/incomplete _RtlAnsiStringToUnicodeString
- unimplemented functions return appropriate error codes
winpr/pipe:
- improved TestPipeCreateNamedPipe
- rewrite the completely broken TestPipeCreateNamedPipeOverlapped test
rdtk:
- improve test and don't blindly return success
winpr/synch:
- fix race condition in TestSynchTimerQueue
winpr/ssspi:
- fix TestEnumerateSecurityPackages printf output
- fix TestQuerySecurityPackageInfo printf output
winpr/environment:
- fix GetEnvironmentStrings printf output
winpr/comm:
- unimplemented functions return appropriate error codes
