* Update ipc/ directory to use mach_port_name_tFlavio Cruz2022-11-302-5/+5
| | | | | | | | | | | | | | | Make it explicit where we use port names versus actual ports. For the 64 bit kernel, port names and ports are of different size so this corrects the syscall arguments and internal structs to have the right size. This patch also uncovered several issues we need to solve to make GNUMach work well on 64 bits. First, the mach_msg call will receive 4 byte port names while the kernel "thinks" they are 8 bytes, which will be a problem. Also, when we send a message, the kernel translates the port names into port pointers in the message copied from user space. This also won't work on 64 bits. In this patch, I added several TODOs to fix the issues later. Message-Id: <Y4cCzNmc6vC4bjsX@viriathus>

* Update mach_debug interfaces to use struct.Flavio Cruz2022-11-251-1/+3
| | | | | | | | | | | | | | | | | | | | | | The new interfaces will be compatible both with a 64 bits kernel and userland and 64 bits kernel and 32 bit userland. Also removed many of the uses of natural_t where an unsigned int suffices. Ideally we should replace natural_t with something more portable such as uintptr_t or a basic int type for counters since for the most part we don't need counters to have the same width as the pointer type. * i386/include/mach/i386/vm_types.h: Define rpc_unsigned_long. * include/mach/mach_types.defs: Define type rpc_vm_offset_t. * include/mach_debug/hash_info.h: Use unsigned int instead of natural_t. * include/mach_debug/mach_debug_types.defs: Update cache_info_t, hash_info_bucket_t, vm_region_info_t, vm_object_info_t and vm_page_info_t to use struct. * include/mach_debug/slab_info.h: Use rpc_vm_size_t and rpc_unsigned_long for compatibility with 32 bits userland. * include/mach_debug/vm_info.h: Update struct fields to use the correct types and avoid natural_t whenever we just want to keep a count of something.

* fix rpc types for KERNEL_USER stubsLuca Dariz2022-08-281-5/+11
| | | | | | | | | | | | | | | * include/mach/mach_types.defs: use rpc_ vm types for KERNEL_USER stubs. This change fixes two use cases: * internal rpc, e.g. when a memory object is initialized as a consequence of vm_map(); for example, the bootstrap modules use the "time" kernel device and memory-map it during startup. This triggers a kernel-side rpc to initialize the memory object and install the map, which is completely transparent form user-space. * notifications from kernel to user-space Signed-off-by: Luca Dariz <luca@orpolo.org> Message-Id: <20220628101054.446126-2-luca@orpolo.org>

* add rpc_versions for vm typesLuca Dariz2022-08-271-3/+28
| | | | | | | | | | | | | | | * vm_types.h: add new types and conversion functions * mach_types.defs: adapt vm types depending on kernel user/server * vm_info.h: adapt rpc structure to have uniformly-sized members also on 64-bit * x86_64/configfrag.c: add new option to select the user-space variant. Note that with this change the user-space interface is somehow fixed, i.e. it can't support 32-bit and 64-bit tasks at the same time. If this would be needed at some point, this change needs to be reworked. Signed-off-by: Luca Dariz <luca@orpolo.org> Message-Id: <20220403145955.120742-3-luca@orpolo.org>

| | | | | | | | | | | | | | | | | | | | * include/mach/mach_port.defs - use C type mach_port_name_array_t * include/mach/port.h: - add new types mach_port_name_t and mach_port_name_array_t - refine mach_port_t type for user and kernel space - use port names in mach_port_status to allow compilation of 64-bit - use port name to have uniform sizes and remove the old_mach_port_status_t as it's unused * include/mach/std_types.defs - use C type mach_port_name_array_t * kern/thread.{h,c} - fix prototype to use port names. So far it seems the only rpc to cause a conflict between the mig-generated header and the regular header, so compilation fails.
