* Consider protected payloads in mach_msg_header_t when resizing messages.Flavio Cruz2023-02-121-1/+8
| | | | | | | | | | Protected payloads will be 8-byte longs which are the same size as kernel ports. Also aligned all the structures to be 4-byte aligned since it makes it easier to parse them as padding won't be added to mach_msg_user_header_t before the protected payload.

* Define rpc_vm_size_array_t and rpc_vm_offset_array_tFlavio Cruz2023-01-311-3/+5
| | | | | | | | | | When generating stubs, Mig will will take the vm_size_array_t and define the input request struct using rpc_vm_size_t since the size is variable. This will turn cause a mismatch between types (vm_size_t* vs rpc_vm_size_t*). We could also ask Mig to produce a prototype by using rpc_vm_size_t*, however we would need to change the implementation of the RPC to use rpc_* types anyway since we want to avoid another allocation of the array.

* Add host_set_time64 and host_adjust_time64Flavio Cruz2023-01-281-0/+18
| | | | | | Same existing logic, just with 64 bits. Old RPCs are implemented by calling into the new RPCs. Message-Id: <Y9TJAmL2byOWup5x@jupiter.tail36e24.ts.net>
* Use standard types in include/device/input.hFlavio Cruz2023-01-281-2/+2
| | | | | | | | | | --enable-platform=xen won't compile because u_char is not included from sys/types.h. Also, we are forcing users of include/device/input.h to include glibc headers that export such types which should not be necessary. For i386/i386at/kd.h we include input.h to get Scancode.

* Rename msg_is_misaligned and msg_alignSamuel Thibault2023-01-191-2/+2
| | | | message.h is installed so we need to hide these behind a mach_ prefix
* Add host_get_time64 RPC to return the time as time_value64_tFlavio Cruz2023-01-193-13/+44
| | | | | | Also updated the mapped time to support the new 64-bit time while keeping compatible with the user land programs currently using it so they can be migrated in parallel.
* replace mach_port_t with mach_port_name_tLuca Dariz2023-01-181-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | This is a cleanup following the introduction of mach_port_name_t. The same set of changes is applied to all files: - rename mach_port_t to mach_port_name_t where a port name is used, - use MACH_PORT_NAME_NULL and MACH_PORT_NAME_DEAD where appropriate, - use invalid_port_to_name() and invalid_name_to_port() for conversion where appropriate, - use regular copyout() insted of copyout_port() when we deal with mach_port_name_t already before copyout, - use the new helper ipc_kmsg_copyout_object_to_port() when we really want to place a port name in the space of a mach_port_t. * include/mach/notify.h: Likewise * ipc/ipc_entry.c: Likewise * ipc/ipc_kmsg.c: Likewise * ipc/ipc_kmsg.h: Likewise, and add ipc_kmsg_copyout_object_to_port() * ipc/ipc_marequest.c: Likewise * ipc/ipc_object.c: Likewise * ipc/ipc_port.c: Likewise * ipc/ipc_space.h: Likewise * ipc/mach_msg.c: Likewise * ipc/mach_port.c: Likewise * kern/exception.c: Likewise * kern/ipc_mig.c: Likewise Message-Id: <20230116105857.240210-8-luca@orpolo.org>

| | | | | | | | | | | | | | | | | | | * i386/i386/copy_user.h: new file to handle 32/64 bit differences - add msg_usize() to recontruct the user-space message size - add copyin/copyout helpers for addresses and ports * include/mach/message.h: add msg alignment macros * ipc/ipc_kmsg.c: - copyin/out ports names instead of using pointer magic * ipc/ipc_mqueue.c: use msg_usize() to check if we can actually receive the message * ipc/mach_msg.c: Likewise for continuations in receive path * x86_64/Makefrag.am: add x86_64/copy_user.c * x86_64/copy_user.c: new file to handle message expansion and shrinking during copyinmsg/copyoutmsg for 64 bit kernels. - port names -> port pointers on all 64-bit builds - 32-bit pointer -> 64 bit pointer when using 32-bit userspace * x86_64/locore.S: remove copyinmsg() and copyoutmsg() Message-Id: <20230116105857.240210-3-luca@orpolo.org>
* add msg_user_header_t for user-side msg structureLuca Dariz2023-01-181-1/+16
| | | | | | | | | | | * include/mach/message.h: use mach_msg_user_header_t only in KERNEL, and define it as mach_msh_header_t for user space * ipc/ipc_kmsg.c: use mach_msg_user_header_t where appropriate * ipc/ipc_kmsg.h: Likewise * ipc/mach_msg.c: Likewise * ipc/mach_msg.h: Likewise * kern/thread.h: Likewise Message-Id: <20230116105857.240210-2-luca@orpolo.org>
* Delete ffs and strrchr prototypes.Flavio Cruz2023-01-151-4/+0
| | | | | | | | We use __builtin_ffs instead of ffs. strrchr is not used. Also removed the commented out memset implementation since it is implemented in arch-specific code. Message-Id: <Y8NOXbVzhBJknR29@mercury.tail36e24.ts.net>
* Use rpc_uintptr_t for protected payloads.Flavio Cruz2023-01-133-2/+4
| | | | | | | Not only is uintptr_t more accurate for what protected payloads are but we also provide compatibility for 64 + 32 bits. Also the use of natural_t in the RPC definition is wrong since it is always 32 bits. Message-Id: <Y7+LHVbmYxO/cSKs@jupiter.tail36e24.ts.net>
* Export input structures used by Hurd in device/input.h.Flavio Cruz2023-01-092-52/+106
| | | | | | Also delete sys/ioctl.h and merge it with device/input.h since it is only needed here. Message-Id: <Y7uirJzaJeOBzAmq@jupiter.tail36e24.ts.net>
* Introduce time_value64_t to keep track of real time in the kernelFlavio Cruz2023-01-032-54/+26
| | | | | | | | | | | | time_value64_t uses int64_t to track seconds and nanoseconds and hence is Y2038 proof. It does not have nano second resolution but it could be provided in the future. Removed include/sys/time.h as it remaps time_value_t into timeval which can create confusion. The timestamp from keyboard and mouse events is no longer set and replaced with rpc_time_value for better compatibility.
* Fix inttypes.h format constants for uintptr_t and intptr_t.Flavio Cruz2022-12-271-9/+11
| | | | | | | | The format constants are not correct for 32 bits and there was duplication for PRIx* constants (replaced with octal constants). Fixed a few format warnings too. Message-Id: <Y6o5KsvtPavCYe8f@mars>
* Use uintptr_t to define vm_size_t/vm_offset_t/vm_addressFlavio Cruz2022-12-271-5/+1
| | | | Message-Id: <Y6j9bnHphZp0ZPYC@mars>
* 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>

* Delete mach_debug/pc_info.hFlavio Cruz2022-11-281-43/+0

* 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.

| | | | | | | | | | | | | | | * 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>

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.
