* replace mach_port_t with mach_port_name_tLuca Dariz2023-01-1812-55/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* x86_64: expand and shrink messages in copy{in, out}msg routinesLuca Dariz2023-01-188-107/+522
| | | | | | | | | | | | | | | | | | | * 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>

| | | | | stack_statistics, swapin_thread_continue, and memory_object_lock_page are not used outside their module.
* Delete x86 string functionsFlavio Cruz2023-01-181-54/+0
| | | | | | The i386 functions are not used and the more portable versions in kern/strings.c are faster (1-4x faster in synthetic benchmarks compiled with -O2 on my x86_64 box). Message-Id: <Y8Yt9FvIagB78uyR@jupiter.tail36e24.ts.net>

* add missing argument namesLuca Dariz2023-01-166-35/+35
| | | | | | | | | | | | | | | * ddb/db_break.c: add argument name, compilation fails on Debian/Linux stable with gcc 10.2 otherwise. For some reason on Debian/Hurd a simple test program without argname succeeds, unless I force -std=c11 or similar; I suppose because newer gcc have different defaults. Gnumach seem to still require c89 for some older code, otherwise we could explicitely use gnu99/c99 or gnu11/c11. * ddb/db_cond.c: Likewise * ddb/db_examine.c: Likewise * ddb/db_macro.c: Likewise * ddb/db_watch.c: Likewise * device/dev_name.c: Likewise Message-Id: <20230116130426.246584-1-luca@orpolo.org>

| | | | | | | | 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>

| | | | | | ad51c68171cb6a1cae15c61ca0218bbee2c05485 missed one replacement which was not discovered because it’s only when building with smp enabled. Message-Id: <20230113144732.49786-1-etienne.brateau@gmail.com>

* Use rpc_uintptr_t for protected payloads.Flavio Cruz2023-01-1310-14/+18
| | | | | | | 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>
* Preemptively fix warnings that will be caused by -Wmissing-prototypesFlavio Cruz2023-01-105-4/+142
| | | | | | | Declared RPCs in ipc/mach_port.c and ddb/db_ext_symtab.c in their corresponding headers. Ideally these should be used by mig instead of mig declaring its own prototypes. Message-Id: <Y7z/BQhmsBbRgxhe@jupiter.tail36e24.ts.net>
* Update configure.ac so that we don't need glibc when running ./configure.Flavio Cruz2023-01-102-2/+10
| | | | | | | For x86_64-pc-gnu we still do not have a working glibc so ./configure will fail under a freestanding environment. We force ./configure to avoid running compiled C programs as a test which it is not needed when compiling a kernel. Message-Id: <Y7zYm44O0CNayuAe@jupiter.tail36e24.ts.net>

* Export input structures used by Hurd in device/input.h.Flavio Cruz2023-01-094-111/+108
| | | | | | 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>
* Set max-page-size when linking the kernel to 0x1000.Flavio Cruz2023-01-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the exception of linux, x86_64 ld default's max-page-size is 2MB (default for i386 is 4K) and compiling gnumach with x86_64-pc-gnu-ld will generate a kernel image where the boot section starts at the file offset 2MB. This makes it unbootable on grub because the file is no longer multiboot. Here's the objdump -h output before the patch: Sections: Idx Name Size VMA LMA File off Algn 0 .boot 0000c000 0000000001000000 0000000001000000 00200000 2**12 CONTENTS, ALLOC, LOAD, READONLY, CODE 1 .text 0009078f 000000004100c000 000000000100c000 0020c000 2**2 CONTENTS, ALLOC, LOAD, READONLY, CODE 2 .rodata 000110fc 000000004109c7a0 000000000109c7a0 0029c7a0 2**5 CONTENTS, ALLOC, LOAD, READONLY, DATA 3 .eh_frame 000101f0 00000000410ad8a0 00000000010ad8a0 002ad8a0 2**3 CONTENTS, ALLOC, LOAD, READONLY, DATA 4 .data 000070a0 00000000412bdaa0 00000000012bdaa0 002bdaa0 2**5 CONTENTS, ALLOC, LOAD, DATA 5 .bss 00023f10 00000000412c5000 00000000012c5000 002c4b40 2**12 ALLOC 6 .comment 00000012 0000000000000000 0000000000000000 002c4b40 2**0 CONTENTS, READONLY After, when forcing ld's max-page-size to be 4K: Sections: Idx Name Size VMA LMA File off Algn 0 .boot 0000c000 0000000001000000 0000000001000000 00001000 2**12 CONTENTS, ALLOC, LOAD, READONLY, CODE 1 .text 0009078f 000000004100c000 000000000100c000 0000d000 2**2 CONTENTS, ALLOC, LOAD, READONLY, CODE 2 .rodata 000110fc 000000004109c7a0 000000000109c7a0 0009d7a0 2**5 CONTENTS, ALLOC, LOAD, READONLY, DATA 3 .eh_frame 000101f0 00000000410ad8a0 00000000010ad8a0 000ae8a0 2**3 CONTENTS, ALLOC, LOAD, READONLY, DATA 4 .data 000070a0 00000000410beaa0 00000000010beaa0 000beaa0 2**5 CONTENTS, ALLOC, LOAD, DATA 5 .bss 00023f10 00000000410c6000 00000000010c6000 000c5b40 2**12 ALLOC 6 .comment 00000012 0000000000000000 0000000000000000 000c5b40 2**0 CONTENTS, READONLY It is also possible that something is wrong with the linker script but couldn't find anything concrete so far.

* Fix ddb warnings introduced with -Wstrict-prototypesFlavio Cruz2023-01-0519-57/+124
| | | | | | | Changed some ddb command functions to have the expected signature but not all of them due to the being difficult to inter-dependency between header files (for those just used cast). Message-Id: <Y7UO9HTfpZ8U0Nfy@mars>
* Introduce time_value64_t to keep track of real time in the kernelFlavio Cruz2023-01-0314-87/+64
| | | | | | | | | | | | 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.
