The branch stable/13 has been updated by jlduran: URL: https://cgit.FreeBSD.org/src/commit/?id=549cba3c9d1e14fffa9a99ed7b6ee51eb6d20e51 commit 549cba3c9d1e14fffa9a99ed7b6ee51eb6d20e51 Author: Jose Luis Duran <jlduran@FreeBSD.org> AuthorDate: 2025-10-17 14:34:55 +0000 Commit: Jose Luis Duran <jlduran@FreeBSD.org> CommitDate: 2025-10-20 16:05:40 +0000 rc: dmesg: Allow umask to be configurable Allow umask to be configurable. Being able to set the umask via an rc variable is useful when setting: security.bsd.unprivileged_read_msgbuf=0 As it allows a user to configure: dmesg_umask="066" Without modifying the rc script, and preventing the contents of the $dmesg_file (/var/run/dmesg.boot) from being publicly readable.
