* Fix various function pointer typesSergey Bugaev2024-12-101-1/+1
| | | | | | | Fixes Wincompatible-pointer-types errors on GCC 15. Signed-off-by: Sergey Bugaev <bugaevc@gmail.com> Message-ID: <20241210115705.710555-1-bugaevc@gmail.com>

* Add thread_set_name RPC.Flavio Cruz2024-02-121-4/+5
| | | | | | | Like task_set_name, we use the same size as the task name and will inherit the task name, whenever it exists. This will be used to implement pthread_setname_np. Message-ID: <20240212062634.1082207-2-flaviocruz@gmail.com>
* Replace kernel header includes in include/mach/mach_types.h with forward ↵Flavio Cruz2024-02-121-0/+1
| | | | | | | | | | | | | | | declarations. I was trying to reuse TASK_NAME_SIZE in kern/thread.h but it was impossible because files included from kern/task.h end up requiring kern/thread.h (through percpu.h), creating a recursive dependency. With this change, mach_types.h only defines forward declarations and modules have to explicitly include the appropriate header file if they want to be able touch those structures. Most of the other includes are required because we no longer grab many different includes through mach_types.h. Message-ID: <20240212062634.1082207-1-flaviocruz@gmail.com>

| | | | | | | | | | | | | | | * 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.

Second, make the VM system track wiring requests to better handle protection. This change makes it possible to wire entries with VM_PROT_NONE protection without actually reserving any page for them until protection changes, and even make those pages pageable if protection is downgraded to VM_PROT_NONE. * ddb/db_ext_symtab.c: Update call to vm_map_pageable. * i386/i386/user_ldt.c: Likewise. * ipc/mach_port.c: Likewise. * vm/vm_debug.c (mach_vm_region_info): Update values returned as appropriate. * vm/vm_map.c (vm_map_entry_copy): Update operation as appropriate.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the port names are mapped to an IPC object (e.g. a port) using a table. This, however, requires large chunks of continuous memory, and leads to scalability problems as virtual kernel memory is a scarce resource.
