[ntp][apparmor] Allow apparmor read permission for ntpd under rw mount path of rootfs (#6040) Certain platform specific packages sonic-platform-xyz, installs files onto rootfs, which would be placed on read-write mount path on /host/image-name/rw/... when ntpd starts it tries to do read access on /usr/bin /usr/sbin/ /usr/local/bin , which inturn links further to the read-write mount path also. Where ntpd would get below Apparmor Warning message LOG:- audit: type=1400 audit(1606226503.240:21): apparmor="DENIED" operation="open" profile="/usr/sbin/ntpd" name="/image-HEAD-dirty-20201111.173951/rw/usr/local/bin/" pid=3733 comm="ntpd" requested_mask="r" denied_mask="r" fsuid=0 ouid=0 audit: type=1400 audit(1606226503.240:22): apparmor="DENIED" operation="open" profile="/usr/sbin/ntpd" name="/image-HEAD-dirty-20201111.173951/rw/usr/sbin/" pid=3733 comm="ntpd" requested_mask="r" denied_mask="r" fsuid=0 ouid=0 audit: type=1400 audit(1606226503.240:23): apparmor="DENIED" operation="open" profile="/usr/sbin/ntpd" name="/image-HEAD-dirty-20201111.173951/rw/usr/bin/" pid=3733 comm="ntpd" requested_mask="r" denied_mask="r" fsuid=0 ouid=0 Fix: Add rw/.. mount path similar to root path access provided for ntpd in /etc/apparmor.d/usr.sbin.ntpd Signed-off-by: Antony Rheneus <arheneus@marvell.com> 2020-12-18 06:57:35 -06:00			`# Apparmor configuration`
