[Bug 1618463] Re: udev race condition with qeth device and bridge_role
@admcleod Based on feedback from IBM i'm going to withdraw this update. The ordering of the flags is correct, as long as one activates the flag needed to have bridge_role attribute available before onlining the device. Specifically one should use: in-target chzdev --no-root-update -pVe c003 layer2=1 bridge_role=primary; meaning... enable layer2 networking, which creates a bunch of attributes specific to layer2 mode, including the bridge_role. Then set bridge_role. Then online the device. Testing this out here locally results in race free boots, without any changes to the code. Could you please try out above command in your preseeds without using packages from proposed?

[Bug 1618463] Re: udev race condition with qeth device and bridge_role
** Description changed:
+ [Impact]
+
+ * bridge_role property setting is racy on boot
+
+ * This results in incorrect bridge mode set on the devices, sometimes,
+ which leads to lack of desired connectivity (e.g. bridging internet to
+ containers)
+
+ * The fix for this issue is to set bridge_role, only after the device
+ is online
+
+ * Unfortunately the udev rules are not regenerated, therefore affected
+ systemd must manually remove and recreate chzdev rules
+
+ [Test Case]
+
+ * Remove qeth udev rules from /etc/udev/rules.d/
+ * Enable qeth device using chzdev with a non-default bridge_role setting,
e.g.:
+chzdev --no-root-update -pVe c003 bridge_role=primary;
+ * Reboot and check that bridge_role setting is correctly set in the sysfs,
e.g.:
+/sys/devices/qeth/0.0.c003/bridge_role
+
+ [Regression Potential]
+
+ * Minimal, the generated udev rules remain the same; the only
+ difference in the generated udev rules is the ordering in setting the
+ bridge_role attribute
+
+ [Other Info]
+
+ * Original bug report:
+
Attempting to set bridge_role = primary with the following command in
preseed:
in-target chzdev --no-root-update -pVe c003 bridge_role=primary;
...works, and generates the following udev rule for this device:
https://pastebin.canonical.com/164271/
However, after reboot:
systemd-udevd[2634]: error opening
ATTR{/sys/devices/qeth/0.0.c003/bridge_role} for writing: Permission
denied
More logging:
https://pastebin.canonical.com/164272/
after the system has booted, we are able to write to the file and set
bridge_role to primary:
- root@10-13-3-10:/var/log# cat /sys/devices/qeth/0.0.c003/bridge_role
+ root@10-13-3-10:/var/log# cat /sys/devices/qeth/0.0.c003/bridge_role
none
root@10-13-3-10:/var/log# echo primary >
/sys/devices/qeth/0.0.c003/bridge_role
- root@10-13-3-10:/var/log# cat /sys/devices/qeth/0.0.c003/bridge_role
+ root@10-13-3-10:/var/log# cat /sys/devices/qeth/0.0.c003/bridge_role
primary

sudo add-apt-repository ppa:ci-train-ppa-service/2038 sudo apt update sudo apt dist-upgrade After that please regenerate persistent configuration for your qeth device, e.g.: $ sudo chzdev -p -d 600 $ sudo chzdev -p -e 600 bridge_role=primary $ sudo update-initramfs -u undo any other manual changes to set bridge_role to primary, and finally reboot to test the packages with a proposed fix for your issue.
