Rewrite function save_err_ptr_str() to not use sprintf()
sprintf() is marked by MSVC as unsafe and suppressing compile warning does
not work. It is still generated on AppVeyor. So rewrite code for converting
pointer number to string via open coded for-loop and do not use unsafe
sprintf() function anymore. New code correctly handles both 32bit and 64bit
variants and does not use any #ifdef _MSC_VER anymore.

variables defined later are hidden on the web interface. Variable

Replace VirtualQueryEx() call by GetModuleHandleExA() call
Usage of VirtualQueryEx() call is needed for retrieving HMODULE of passed
function address and it is just an undocumented hack. Based on @rhabacker's
tests it is unstable and does not work correctly.
https://github.com/dlfcn-win32/dlfcn-win32/pull/72#issuecomment-656581418
So replace VirtualQueryEx() call by standard GetModuleHandleExA() function
with special GET_MODULE_HANDLE_EX_FLAG_FROM_ADDRESS flag which should do
the same thing but it is documented and it is working correctly.

Show "(null)" in error message when passed filname to dlopen() was NULL and error occurred
It does not make sense to pass file variable (which is NULL) to function
save_err_ptr_str() which converts its argument to string. We can call
directly save_err_str() with string value.
Also it is highly unexpected that GetModuleHandle(NULL) call fails.

Fix gcc warning: ISO C forbids return between function pointer and void *
Instead of using compiler specific pragma to disable particular warning,
rewrite code which cast from function pointer to data pointer according to
POSIX dlopen() documentation. This also fix compile warning under MSVC.
According to the ISO C standard, casting between function
pointers and 'void *', as done above, produces undefined results.
POSIX.1-2003 and POSIX.1-2008 accepted this state of affairs and
proposed the following workaround:
*(void **) (&cosine) = dlsym(handle, "cos");
This (clumsy) cast conforms with the ISO C standard and will
avoid any compiler warnings.

Do not include intrin.h file
Include file intrin.h is not needed for compiling dlfcn.c as _ReturnAddress
intrinsic is defined in dlfcn.c manually. Moreover _ReturnAddress is
available only as an intrinsic, there is no function implementation. So
even including intrin.h file does not provide function variant for
_ReturnAddress.
More important, include file intrin.h is not available in older Windows
Driver Kit 7.1.0. So removing usage of intrin.h file makes compilation of
dlfcn-win32 also under these older WDK versions.

E.g. LoadLibraryExA() instead of LoadLibraryEx() or FormatMessageA()
instead of FormatMessage().
This simplify whole implementation when compiling with UNICODE support as
there is no need to do conversion from wchar_t to char and vice-versa.

Fix resolving global symbols and implement RTLD_DEFAULT and RTLD_NEXT
|

|

|
2019-01-29T22:57:04
|
|
Implement support for dlsym() with RTLD_DEFAULT and RTLD_NEXT
dlsym() with RTLD_DEFAULT handle behaves in same way like with global handle
returned by dlopen() with NULL file name.
dlsym() with RTLD_NEXT handle search for next loaded module which provides
specified symbol. "Next" means module which in EnumProcessModules() result
after the module which called dlsym().
To get caller function of dlsym() use _ReturnAddress() intrinsic. To get
module where is caller function use the fact that HMODULE is the same value
as the module's base address.
When compiling under gcc, defines _ReturnAddress() macro via gcc's builtin
as it does not provide MSC's specific _ReturnAddress() intrinsic.
Added tests demonstrate that both RTLD_DEFAULT and RTLD_NEXT are working as
expected.

Fix resolving global symbols when LoadLibrary() is called after dlopen()
Usage of first_automatic_object cache is wrong. This cache is filled by all
loaded DLL files (either implicitly or explicitly with LoadLibrary() call)
by EnumProcessModules() call at first usage of dlopen(). So dlsym() can
resolve global symbols only if they were loaded prior to dlopen() call. Any
future usage of LoadLibrary() does not include newly loaded DLLs into
first_automatic_object cache.
To fix this problem, first_automatic_object cache is fully removed and
EnumProcessModules() call is issued directly in dlsym() call.
As EnumProcessModules() returns all DLLs, included those which were loaded
by dlopen() with RTLD_LOCAL, it may break RTLD_LOCAL support. To address
this problem switch linked-list of all loaded DLLs with RTLD_GLOBAL to
linked-list of all loaded DLLs with RTLD_LOCAL flag. And then skip modules
from EnumProcessModules() which are in linked-list.
Also in WinAPI all DLLs loaded by LoadLibrary() behaves like RTLD_GLOBAL.
So above change is compatible with this behavior.
There may be another problem. Before retrieving HMODULE for DLL filename
(which is done by LoadLibrary()), it is not possible to detect if DLL was
already loaded by RTLD_LOCAL or not. And after calling LoadLibrary() it is
not possible to know if DLL was loaded either by dlsym() with RTLD_LOCAL or
by LoadLibrary() (which is equivalent to RTLD_GLOBAL). To address this
problem, compare number of loaded modules (counted by EnumProcessModules())
before and after LoadLibrary() called from dlsym(). If number does not
change it means that DLL was already loaded. So based on this result either
add or remove HMODULE from linked-list of RTLD_LOCAL modules.
Added test demonstrate usage of:
global = dlopen(NULL, RTLD_GLOBAL); /* global handle */
LoadLibrary("library.dll"); /* this provides function */
function = dlsym(global, "function"); /* resolve function from library.dll */

Fix bug in dlerror second consecutive call
According to the specs, a second consecutive call
to dlerror should always return NULL .

on the second consecutive call.
In this commit the issue is fixed as suggested in

Fix tests in Visual Studio 2015
For checking the loading of symbols from the global handle,
the printf symbol was loaded, but since Visual Studio 2015
printf is defined as a inline function.
To fix this, the test has been modified to load the symbol
of the fwrite function.
