| * | module: Replace cur_module with module_current()syslinux-5.01-pre4Matt Fleming2013-01-231-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's easy for cur_module and prev_module to get out of sync with reality (the actual module that is running), so add module_current() which returns the module at the head of the module_list, i.e. the module that was loaded most recently. Better still, by using the list we don't have to do any kind of stacking of module pointers ourselves. This fixes a bug where cur_module contained a stale pointer (the module had actually been unloaded) but the pointer value had since been reallocated for a new module in spawn_load(), meaning that the following check, if (!strcmp(cur_module->name, module->name)) was always going to be true, even though *no* module was actually loaded at this point as we were reloading ldlinux.c32 from start_ldlinux(). This could have been fixed with a NULL-assignment after module_unload(), but using the modules_head list to detect the current module is much cleaner. Note that the core module loaded in load_env32() is always on the list, therefore module_current() will always return a valid pointer. Signed-off-by: Matt Fleming <matt.fleming@intel.com>

We need to replicate this because most callers of execute() don't expect it to return. This bug was noticed when loading a COM32 module from vesamenu.c32. Once execution returned from the COM32 module the display became garbled because no code exists to reinitialise the screen for VGA. Signed-off-by: Matt Fleming <matt.fleming@intel.com>

| * | ldlinux: Loading a config file should cause re-initialisationMatt Fleming2012-03-231-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are a number of initialisation steps that need to be performed *every* time a config file is loaded. Reload ldlinux.c32 so that we can re-initialise the environment whenever a new config file is loaded. This involves unloading all the modules that have been loaded since ldlinux.c32. Luckily the list of loaded modules is sorted by load order, which means it's trivial to "pop" them from the front of the list. Signed-off-by: Matt Fleming <matt.fleming@intel.com>
| * | elf: Support __constructor and __destructorMatt Fleming2012-03-232-45/+10

Instead, the only way to get similiar behaviour was by using the MODULE_INIT() and MODULE_EXIT() macros, but no one seems to have bothered converting the old __constructor users over. Anyway, the old way is superior because it allows multiple functions be specified. Delete the MODULE_* macros as there's only one user of them in the entire tree. We can also get rid of the UNKNOWN_MODULE constant because now a module doesn't need a __module_init_ptr symbol to be classed as a library - if a module isn't an executable, it's a library, there's no such thing as an unknown type. It's no longer necessary to explicitly call __syslinux_get_ipappend_strings() from ldlinux.c because the __constructor tag on the version in com32/lib/syslinux will take care of invoking it before ldlinux.c32's main() is executed. Also, since we've refactored unload_module() to now run a module's destructors let's minimise the number of callers by deleting load_library() and unload_library(), which were only called by the test module in com32/elflink.

* | | The ELF module load and the utility library routines fully support lookup, ↵chandramouli narayanan2012-06-254-363/+795

With this, syslinux.efi built for i386 and x86_64 can load the respective native command modules dynamically. The architecture dependent files are split into respective subdirectories (com32/lib/sys/module/i386 & com32/lib/sys/module/x86_64) for the build environment to pick. Files changed for commit: com32/include/sys/elfcommon.h com32/include/sys/module.h and its i386/ x86_64/ specific files com32/lib/sys/module/i386/common.[ch] and its counterpart in x86_64 com32/lib/sys/module/i386/elfutils.h and its counterpart in x86_64 com32/lib/sys/module/i386/elf_module.c and its counterpart in x86_64 com32/lib/sys/module/i386/shallow_module.c and its counterpart in x86_64 The implementation of com32/elflink/load_env32.c now takes care of both i386 and x86_64 to set up elf module system. Remanants of the unused old i386-only files, if any, need to be pruned.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move the standard definitions of constants, variously-sized ints,limits into respective architecture specific files. com32/include/bitsize holds the standard header files that in turn include bitsize32 or bitsize64 based on the architecture. The makefiles should build pick the right ones based on architecture. Files com32/include/sys/cpu.h, com32/include/sys/bitops.h now have architecture specific files underneath to define relevant macros definitions. com32/include/setjmp.h has architecture specific counterparts underneath. ssize_t in dos/stdlib.h is appropriately defined based on architecture to be able to support building for 32bit and 64bit environments. Remanants of the unused old i386-only files, if any, need to be pruned.
* | ldlinux: Use DT_NEEDED for module dependenciesMatt Fleming2011-06-071-12/+0
| | | | | | | | | | | | | | | | | | The ELF file format uses DT_NEEDED entries in the dynamic section to name any shared library dependencies.

* | elflink: Move more code from core/ into ldlinuxMatt Fleming2011-04-261-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ldlinux now contains all the code necessary to load and execute modules, none is contained in the core. This change also allows us to change the spawn_load() prototype and to push the job of processing arguments to executable functions (e.g. the contents of char *argv[] as passed to a module's main function) into ldlinux/execute.c instead of doing it in spawn_load(). Moving it into ldlinux/ makes sense because the only core user of spawn_load() is load_env32() and we don't require any sort of argument processing in that path.

* | elflink: Remove MODULE_MAIN() from executable ELF modulesMatt Fleming2011-04-261-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To make it easier to move existing COM32 modules over to ELF modules without having to modify them we need to search for and run their main() functions when they're loaded instead of requiring their initial function to be labeled with MODULE_MAIN(). Currently, we require all executable ELF modules to specify their initial function with the use of the MODULE_MAIN() macro and not via the traditional method of naming it main(). However, there are weird restrictions on what functions can be passed to MODULE_MAIN(), for instance, they must be declared static. This patch makes life much simpler and allows executable ELF modules to be loaded without the MODULE_MAIN() wrapper, but rather by naming their initial function main(). All the modules in com32/modules can now be run as ELF modules without any modifications. Signed-off-by: Matt Fleming <matt.fleming@linux.intel.com>
