Public bug reported: On October 9 the NetworkManager tests started failing (https://jenkins.qa.ubuntu.com/view/Saucy/view/AutoPkgTest/job/saucy- adt-network-manager/?). Unfortunately the more recent saucy logs got lost, but the trusty ones have the information, like in
https://jenkins.qa.ubuntu.com/view/Trusty/view/AutoPkgTest/job/trusty- adt-network-manager/1/ARCH=i386,label=adt/ In these, dhclient that gets called through NetworkManager and /usr/lib/NetworkManager/nm-dhcp-client.action cannot access the system D-BUS any more: ----------- NM log ------------ NetworkManager[24451]: <info> Activation (eth42) Stage 3 of 5 (IP Configure Start) complete. Internet Systems Consortium DHCP Client 4.2.4 Copyright 2004-2012 Internet Systems Consortium. All rights reserved. For info, please visit https://www.isc.org/software/dhcp/ Error: could not get the system bus. Make sure the message bus daemon is running! Message: (org.freedesktop.D Bus.Error.AccessDenied) Failed to connect to socket /var/run/dbus/system_bus_socket: Permission denied ----------- NM log ------------ In syslog, you see this at that time: ------------ syslog --------- Oct 21 14:11:24 autopkgtest kernel: [ 288.320754] type=1400 audit(1382364684.505:21): apparmor="DENIED" operation="connect" info="Failed name lookup - disconnected path" error=-13 parent=18759 profile="/usr/lib/NetworkManager/nm-dhcp-client.action" name="run/dbus/system_bus_socket" pid=18760 comm="nm-dhcp-client." requested_mask="rw" denied_mask="rw" fsuid=0 ouid=0 Oct 21 14:11:24 autopkgtest kernel: [ 288.333814] type=1400 audit(1382364684.517:22): apparmor="DENIED" operation="sendmsg" info="Failed name lookup - disconnected path" error=-13 parent=18752 profile="/sbin/dhclient" name="dev/log" pid=18759 comm="dhclient" requested_mask="w" denied_mask="w" fsuid=0 ouid=0 ------------ syslog --------- This gets fixed if I do "sudo /etc/init.d/apparmor teardown". But it does not seem to be a problem with the policy itself; if I do "sudo aa- complain dhclient" then dmesg changes to [ 8054.314704] type=1400 audit(1382609088.727:672): apparmor="ALLOWED" operation="sendmsg" info="Failed name lookup - disconnected path" error=-13 parent=24451 profile="/sbin/dhclient" name="dev/log" pid=24736 comm="dhclient" requested_mask="w" denied_mask="w" fsuid=0 ouid=0 [ 8054.341409] type=1400 audit(1382609088.755:673): apparmor="ALLOWED" operation="connect" info="Failed name lookup - disconnected path" error=-13 parent=24736 profile="/usr/lib/NetworkManager/nm-dhcp-client.action" name="run/dbus/system_bus_socket" pid=24737 comm="nm-dhcp-client." requested_mask="rw" denied_mask="rw" fsuid=0 ouid=0 So this doesn't look like a problem with the policy but rather with some internal AppArmor name parsing? I found an old bug 955892 with the same error message, but that got fixed a while ago, and this does not involve ecryptfs or anythign similar. It's just a plain trusty VM with the NetworkManager autopkgtest. ** Affects: apparmor (Ubuntu) Importance: Undecided Status: New ** Tags: autopkgtest ** Summary changed: - "Failed name lookup - disconne cted path" in dhclient D-BUS access + "Failed name lookup - disconnected path" in dhclient D-BUS access ** Tags added: autopkgtest -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1244157 Title: "Failed name lookup - disconnected path" in dhclient D-BUS access To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/1244157/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
