* pkru: Fix handling of 1GB largepage mappingsMark Johnston2026-04-211-0/+3
| | | | | | | | | | | | | | pmap_pkru_update_range() did not handle the case where a PDPE has PG_PS set. More generally, the SET_PKRU and CLEAR_PKRU sysarch implementations did not check whether the request covers a "boundary" vm map entry. Fix this, add the missing PG_PS test, and add some tests.

* pkru.3: Note that the kernel may not respect PKRU protectionsMark Johnston2026-04-161-7/+10
| | | | | | | | | | | | | | | There are cases where the kernel will be able to access memory covered by a PKRU key which nomially prohibits accesses. I believe regular copyin()/copyout() are subject to the contents of PKRU, but memory accesses via uiomove_fromphys() will not be. This can arise when performing fault I/O, for instance. I didn't test, but I suspect AIO is another case. Update the man page to acknowledge this. Reviewed by: alc, kib MFC after: 1 week Differential Revision: https://reviews.freebsd.org/D56416
* pkru.3: Remove a qualifierMark Johnston2026-04-161-3/+0
| | | | | | | | | | Now that i386 kernels are deprecated, we don't really need to mention this limitation. It's also a bit dated since PKRU is supported with 5-level paging as well. Reviewed by: alc, kib MFC after: 1 week Differential Revision: https://reviews.freebsd.org/D56415

* libc: Move per-arch sys/Makefile.inc to libsysBrooks Davis2024-02-052-0/+103
| | | | | | | | | | | | | | | libc/<arch>/sys/Makefile.inc -> libsys/<arch>/Makefile.sys. Require that libsys/<arch>/Makefile.sys exist. At least for current archtiectures, it's not possible for an architecture to not have and MD syscall bits. powerpcspe/Makefile.sys's structure means it had to be modified when moved so rename detection won't work, but it has trivial contents so the history is unimportant.
