pkru.3: Note that the kernel may not respect PKRU protections 2026-04-16T17:46:11+00:00 Mark Johnston markj@FreeBSD.org 2026-04-16T17:46:11+00:00 fa77fecb0e06ec697e3d7a9ed899e568f1d2090c 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

lib/libifconfig: Fix pointer-sign warnings 2026-04-16T06:05:22+00:00 Ryan Moeller rmoeller.dev@gmail.com 2025-09-18T15:04:35+00:00 20cd1b475a1ef9dfca30726999aa1b9a02d5bc39 Fix all pointer-sign warnings generated when compiling libifconfig. One of these warnings comes from the misuse of snl_add_msg_attr_string for a byte array. Though userland treats carpr_key as a string, it is actually an array of bytes. Handle it as such in libifconfig. While here, fix a small consistency nit in ifconfig_sfp_get_sfp_dump.
