Subject: [PATCH] teamd: do no remove the ports on shutdown with -N
|
||||
|
||||
With -N, teamd currently leaves the team device in place on shutdown,
|
||||
as it's supposed to, but it removes all the ports. This severely limits
|
||||
usefullness of the option, because it's still impossible to replace
|
||||
the daemon with another one without disrupting connectivity.
|
||||
|
||||
One use case where this is important is the handover from initrd to real
|
||||
root, when a team device was used to provide connectivity to a network
|
||||
root filesystem:
|
||||
|
||||
Systemd's isolation of switch-root.target stops NetworkManager.service and
|
||||
then terminates its kids, including teamd. The real NetworkManager.service
|
||||
would eventually catch up and restart it, but there's a short period when
|
||||
team ports are removed which is not great if we're booting off that device.
|
||||
Also, it may be that ports come up in different order, causing team to get
|
||||
a different MAC address, which will invalidate the DHCP lease we got
|
||||
beforehands and screwing up L3 addressing.
|
||||
|
||||
Let's not flush the ports when -N is used.

|

|

What has happened is that libdbus called the remove_watch callback twice
|
||||
in a single go, causing two callbacks being destroyed in one iteration
|
||||
of teamd_run_loop_do_callbacks()'s list_for_each_node_entry_safe().
|
||||
|
||||
This basically turns the _safe() variant of the macro unhelpful, as tmp
|
||||
points to stale data anyway.
|
||||
|
||||
Let's use the unsafe variant then, and terminate the loop once
|
||||
teamd_loop_callback_del() asks for main loop's attention via
|
||||
teamd_run_loop_restart(). If there are other callbacks pending an action,
|
||||
they will get their turn in the next main loop iteration.
