Subject: [PATCH] acd: poll the acd fd after starting the announcements
|
|
|
97acb4 |
|
|
|
97acb4 |
In nm_acd_manager_announce_addresses() we should not only start the
|
|
|
97acb4 |
probes but also add the acd file descriptor to the main loop.
|
|
|
97acb4 |
Otherwise, a timer is armed to send the announcements but it never
|
|
|
97acb4 |
fires and no announcements are sent.
|
|
|
97acb4 |
|
|
|
97acb4 |
Fixes: d9a4b59c18e3 ('acd: adapt NM code and build options')
