* Make -fno-PIE etc. architecture-dependentSergey Bugaev2024-03-271-4/+0
| | | | | | | | | | There might be good reasons why Mach on x86 shouldn't be built as PIC/ PIE, but there are also very good reasons to support PIE on other architectures. Potentially implementing KASLR is one such reason; but also the Linux AArch64 boot protocol (that the AArch64 port will use for booting) lets the bootloader load the kernel image at any address, which makes PIC pretty much required.

* Resurrect x86-linux build.Janneke Nieuwenhuizen2024-01-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | This avoids using system headers, which may result in kern/strings.c: In function 'strchr': kern/strings.c:188:32: error: 'NULL' undeclared (first use in this function) In file included from util/atoi.c:77: ./util/atoi.h:65:29: error: unknown type name 'u_char' device/net_io.c: In function 'bpf_do_filter': device/net_io.c:1636:34: error: 'u_int' undeclared (first use in this function); did you mean 'int'?

* Use $(CC) instead of gcc to avoid relying on the host gcc.Flavio Cruz2023-01-301-1/+1
| | | | Message-Id: <Y9dxQ6RqNPZwWBG2@jupiter.tail36e24.ts.net>
* Enable -Wmissing-prototypes.Flavio Cruz2023-01-291-1/+1
| | | | | | | | | | * Makefile.am: enable -Wmissing-prototypes * ddb/db_inout.h: Prototype kdb_kintr for entering into DDB. * ddb/db_mp.c Include ddb/db_input.h to get kdb_kintr. * i386/i386at/kd.h: Include ddb/input.h to get kdb_kintr. * linux/Makefrag.am: Disable some of the new warnings for linux drivers, otherwise we will get more and more noise. Message-Id: <Y9YNfNaYSsZJFST5@mercury.tail36e24.ts.net>
* Remove existing old style definitions and use -Wold-style-definition.Flavio Cruz2023-01-191-1/+1
| | | | Message-Id: <Y8mYd/pt/og4Tj5I@mercury.tail36e24.ts.net>
* adjust rdxtree key to the correct sizeLuca Dariz2023-01-181-0/+3
| | | | | * Makefile.am: define RDXTREE_KEY_32 Message-Id: <20230116105857.240210-6-luca@orpolo.org>
* Update configure.ac so that we don't need glibc when running ./configure.Flavio Cruz2023-01-101-2/+2
| | | | | | | 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>
* Introduce time_value64_t to keep track of real time in the kernelFlavio Cruz2023-01-031-1/+1
| | | | | | | | | | | | 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.
* ld_magic_routines: Restore yet more symbolSamuel Thibault2022-12-241-1/+1
| | | | | | cef6d34aa026 ("Implement our own functions to convert between host and network values") dropped the glibc pieces from clib_routines, but dropped too many ld symbols.
* ld_magic_routines: Restore more more symbolsSamuel Thibault2022-12-241-1/+1
| | | | | | cef6d34aa026 ("Implement our own functions to convert between host and network values") dropped the glibc pieces from clib_routines, but dropped too many ld symbols.
* Use -Wstrict-prototypes and fix warningsFlavio Cruz2022-12-211-1/+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>
* Remove custom stdint.h and rely on freestanding headersFlavio Cruz2022-12-191-1/+2
| | | | | GCC already provides this so we don't need to have our own. Message-Id: <Y5+02FVA6jf4GPgA@mars>
* libgcc_routines: Restore some symbolsSamuel Thibault2022-12-181-1/+1
| | | | | | cef6d34aa026 ("Implement our own functions to convert between host and network values") dropped the glibc pieces from clib_routines, but missed moving all its gcc symbols into libgcc_routines.
* Implement our own functions to convert between host and network valuesFlavio Cruz2022-12-171-12/+8
| | | | | | | | We add htonl, ntohl and ntohs which were the last symbols we relied on from libc. The Makefile.am file was updated to reflect the fact that we only require libgcc. Message-Id: <Y5zNdOJ/YnyYCOhX@mars>
* Use __builtin_ffs instead of libc provided ffs in vm_map.cFlavio Cruz2022-12-151-2/+2
| | | | | | We already use this built-in in other places and this will move us closer to being able to build the kernel without libc. Message-Id: <Y5l80/VUFvJYZTjy@jupiter.tail36e24.ts.net>

| | | | | | | | | When stealing the memset function from the 32bit host libc on a 64bit host system, glibc tends to bring unwanted references to _Unwind_Resume, __gcc_personality_v0, etc. So let's stop stealing memset. * kern/strings.c (memset): New function. * Makefile.am (clib_routines): Remove memset.
