[Bug 596859] Re: ntp profile denies write access to serial devices
This appears to be broken again, the 10.04 default profile has:
# vim:syntax=apparmor
# Last Modified: Tue Aug 11 16:14:21 CDT 2009
# Updated for Ubuntu by: Jamie Strandboge ja...@canonical.com
snip
@{NTPD_DEVICE} r,
So it only allows read-access to the devices. Also broken/reverted is
the tunables which has:

#Add your ntpd devices here eg. if you have a DCF clock
# @{NTPD_DEVICE}=/dev/ttyS*
@{NTPD_DEVICE}=/dev/tty10
Again, no default access to serial ports and modification date is before
the message #4 (above). Can this be fixed again and pushed back to
debian so it stays fixed?

[Bug 596859] Re: ntp profile denies write access to serial devices
Paul,
Thank you for taking the time to report this bug and helping to make
Ubuntu better.
I've just checked the current development version, and I see
@{NTPD_DEVICE} rw in /etc/apparmor.d/usr.sbin.ntpd and
@{NTPD_DEVICE}=/dev/null in /etc/apparmor.d/tunables/ntpd.
You said that you're using 10.04. This is an older release than where
the bug was fixed in, so this would make sense. If you are using an old
release, a workaround is to fix /etc/apparmor.d/usr.sbin.ntpd by hand.
Even in the current release, it appears that it is intended and required
to specify the serial port device in /etc/apparmor.d/tunables/ntpd.
So as far as I can determine, this bug is fixed in the current
development version and there has been no regression. But if I'm
mistaken, please let us know!

[Bug 596859] Re: ntp profile denies write access to serial devices
Thanks Robie for the quick reply, but I though 10.04.4 LTS would have such bug-fixes included? After all the ISO used to install is from after the date of the fix, and the major package numbers are the same (comment #1 mentions 1:4.2.4p8 +dfsg-1ubuntu4 and my machine is reporting 1:4.2.4p8+dfsg-1ubuntu2.1) -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to ntp in Ubuntu. https://bugs.launchpad.net/bugs/596859 Title: ntp profile denies write access to serial devices To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ntp/+bug/596859/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 596859] Re: ntp profile denies write access to serial devices
Paul, In order to maintain stability, a stable release only gets bugfixes backported if they are deemed severe enough. I'm not sure that this bug qualifies, because it only affects a small number of users (those with hardware clocks) and a trivial workaround is available.
