* Use -Wstrict-prototypes and fix warningsFlavio Cruz2022-12-212-3/+1
| | | | | | | Most of the changes include defining and using proper function type declarations (with argument types declared) and avoiding using the K&R style of function declarations. Message-Id: <Y6Jazsuis1QA0lXI@mars>
* time_value: Fix usage in e.g. c89 programsSamuel Thibault2022-12-191-2/+2
| | | | | | The inline keyword was not defined there, so we need to use __inline__. This fixes make check in glibc.
* Remove custom stdint.h and rely on freestanding headersFlavio Cruz2022-12-192-73/+0
| | | | | GCC already provides this so we don't need to have our own. Message-Id: <Y5+02FVA6jf4GPgA@mars>
* Use long_natural_t for recnum_tFlavio Cruz2022-12-182-2/+12
| | | | | | | | | | | | For 64 bits, device operations will provide an addressing space of 64 bits. Also define the translation functions if long_natural_t or long_integer_t are ever used in RPCs. Note that MIG does not implicitly inherit the translation functions from types hence the need to redefine them for recnum_t. Message-Id: <Y59MFzekEA0YUXIw@mars>
* Use struct for time_value_t and define seconds as long_integer_t.Flavio Cruz2022-12-172-2/+38
| | | | | | | On 64 bit kernels, seconds will be 64 bits long and won't suffer from the 2038 problem. We also add a new type rpc_time_value_t to handle the conversion between 32 bit userland and 64 bit kernel. Message-Id: <Y50kIaIgaIdGjDAk@mars>
* Define vm_size_t and vm_offset_t as __mach_uintptr_t.Flavio Cruz2022-12-061-1/+1
| | | | | | | | | | This allows *printf to use %zd/%zu/%zx to print vm_size_t and vm_offset_t. Warnings using the incorrect specifiers were fixed. Note that MACH_PORT_NULL became just 0 because GCC thinks that we were comparing a pointer to a character (due to it being an unsigned int) so I removed the explicit cast. Message-Id: <Y47UNdcUF35Ag4Vw@reue>
* Make task_info.h structs more portableFlavio Cruz2022-12-063-22/+22
| | | | | | | | | | Changed vm_size_t to rpc_size_t so that both userland and kernel agree on the same size. Also changed the denominator for the maximum struct sizes to be integer_t to match the other declarations. Introduced long_natural_t and rpc_long_natural_t to represent large counters. Replaced rpc_unsigned_long with rpc_long_natural_t. Message-Id: <Y47UhaOzKnqhgYq4@reue>
* task: Add task_set_essentialSamuel Thibault2022-12-031-0/+8
| | | | | | | | Whenever a Hurd essential task crashes, startup just reboots the system since there's not much that can be done at that point. When we have a kernel debugger, however, we could at least get crashing information, so let's let Hurd's startup tell the kernel which tasks are essential, and trigger the debugger whenever they crash.
* 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>
* Use portable rpc types to define 'struct sample'.Flavio Cruz2022-11-282-5/+11
| | | | Message-Id: <Y4QQFkTUR4M60Gx0@viriathus>
* Update mach_port_status_t definition to use the new structFlavio Cruz2022-11-282-8/+18
| | | | | Also update C definition to use proper types. Message-Id: <Y4QKgh0zHdB8pWhD@viriathus>
* Delete mach_debug/pc_info.hFlavio Cruz2022-11-281-43/+0
| | | | | mach/pc_sample.h has the definitions that the kernel actually uses. Message-Id: <Y4QKGtUdbz+AVO3l@viriathus>
* Update mach_debug interfaces to use struct.Flavio Cruz2022-11-255-36/+93
| | | | | | | | | | | | | | | | | | | | | | 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.

Message-Id: <Y2dD7Z60Bwybg4jF@viriathus>
* std_types: Drop char, short and int type definitionsSamuel Thibault2022-09-181-3/+0
| | | | | These are provided by mig since ecf59842e472 ("Make MIG recognize the basic C integral types."), released in snapshot v1.8+git20200618.
* copyinmsg: Set msgh_size inside copyinmsg rather than the callerSamuel Thibault2022-08-281-1/+1
| | | | | In the 32/64 conversion case it is copyinmsg that will know the eventual size.
* fix host_info structure definitionLuca Dariz2022-08-281-1/+1
| | | | | | | | | * include/mach/host_info.h: replace vm_size_t with rpc_ version for 64 bit compatibility. Ideally it should use phys_addr_t or another unit like KB or MB Signed-off-by: Luca Dariz <luca@orpolo.org> Message-Id: <20220628101054.446126-8-luca@orpolo.org>
* 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 missing const_mach_port_name_array_t typeSamuel Thibault2022-08-281-0/+1
|
* Fix inclusability of <mach/mach_types.h>Samuel Thibault2022-08-281-25/+14
| | | | | Now that mach/machine/vm_types.h uses stdint types, we have to ship a header that defines them.
* add rpc_versions for vm typesLuca Dariz2022-08-272-15/+40
| | | | | | | | | | | | | | | * 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>
* add port name typesLuca Dariz2022-08-273-9/+21
| | | | | | | | | | | | | | | | | | | | * 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.

* cleanup multibootLuca Dariz2022-08-271-82/+0

* device_read: Add dealloc for dataSamuel Thibault2021-08-211-1/+1
| | | | | | | | | It would be very tricky for the server to manage deallocation for device_read, and does not seem useful anyway. device_reply.defs already has it. * include/device/device.defs (device_read): Add dealloc flag for the data array.
* memory_object_proxy: Explicit that creation wants a send rightSamuel Thibault2021-08-091-2/+2
| | | | This is required anyway, and allows the caller to pass on MAKE_SEND.
* vm_map: Fix taking into account high bits in maskSamuel Thibault2020-12-201-0/+2
| | | | | | | | | | | glibc's sysdeps/mach/hurd/dl-sysdep.c has been wanting to use this for decades. * include/string.h (ffs): New declaration. * vm/vm_map.c: Include <string.h>. (vm_map_find_entry_anywhere): Separate out high bits from mask, to compute the maximum offset instead of map->max_offset. * doc/mach.texi (vm_map): Update documentation accordingly.

* Add vm_allocate_contiguous RPCSamuel Thibault2020-07-091-0/+24
| | | | | | | | | | | | | | | | | This allows privileged userland drivers to allocate buffers for e.g. DMA, and thus need them to be physically contiguous and get their physical address.
