The branch releng/14.0 has been updated by markj: URL: https://cgit.FreeBSD.org/src/commit/?id=abf5807ffc36516976426a83d94caf135d3ea814 commit abf5807ffc36516976426a83d94caf135d3ea814 Author: Gleb Smirnoff <glebius@FreeBSD.org> AuthorDate: 2023-10-26 09:59:21 +0000 Commit: Mark Johnston <markj@FreeBSD.org> CommitDate: 2023-10-26 20:28:23 +0000 bhyve: fix arguments to ioctl(VMIO_SIOCSIFFLAGS) ioctl(2)'s with integer argument shall pass command argument by value, not by pointer. The ioctl(2) manual page is not very clear about that. See sys/kern/sys_generic.c:sys_ioctl() near IOC_VOID.
