Bug ID: 261298
Summary: ntpd: /var/db/ntpd.leap-seconds.list wrong
permissions/owner
Product: Base System
Version: 13.0-RELEASE
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: conf
Assignee: bugs@FreeBSD.org
Reporter: martin@waschbuesch.de
Regularly, /var/db/ntpd.leap-seconds.list ends up being owned by root and
permissions of 640.
On restart of ntpd this leads to:
Jan 18 06:14:56 ns00 ntpd[30173]: leapsecond file
('/var/db/ntpd.leap-seconds.list'): open failed: Permission denied
The file should either be owned by ntpd (which ntpd runs as) or have
permissions of 644.
This happens because
a) the file is owned by root:wheel and
b) I changed umask in /etc/login.conf to 027
ntpd settings in rc.conf are:
ntpd_enable="YES"
ntpd_sync_on_start="YES"
ntpd leapfile is checked and fetched daily as specified in
/etc/periodic/daily/480.leapfile-ntpd
the logic is contained in the ntpd_fetch_leapfile() function within
/etc/rc.d/ntpd
That function should take care of correct ownership of the file, so I propose
to fix ownership to ntpd:ntpd there. However, there may be reasons why
ownership root:wheel and permissions 644 is a better idea for some reason I
have missed, thus I am not providing a patch.
