Public bug reported:
In Xenial, running linux 4.4.0-15-generic and procps 2:3.3.10-4ubuntu2,
I see that the security data column has changed to displaying the
AppArmor confinement mode:
$ ps wZ $(pidof cups-browsed)
LABEL PID TTY STAT TIME COMMAND
/usr/sbin/cups-browsed (enforce) 786 ? Ssl 0:00
/usr/sbin/cups-browsed
This is different than what is displayed in 15.10:
$ ps wZ $(pidof cups-browsed)
LABEL PID TTY STAT TIME COMMAND
/usr/sbin/cups-browsed 548 ? Ssl 0:00
/usr/sbin/cups-browsed
There was a large AppArmor kernel change in Xenial's 4.4.0-15-generic so
to rule that out, I booted into an earlier Xenial kernel and saw the
same issue:
$ uname -a
Linux sec-xenial-i386 4.4.0-7-generic #22-Ubuntu SMP Thu Feb 18 20:50:09 UTC
2016 i686 i686 i686 GNU/Linux
$ ps wZ $(pidof cups-browsed)
LABEL PID TTY STAT TIME COMMAND
/usr/sbin/cups-browsed (enforce) 631 ? Ssl 0:00
/usr/sbin/cups-browsed
