[release-4.17] OCPBUGS-60890: Race in configure-ovs.sh affects bonding interface configuration. #5267
Conversation
Bonded network configurations with mode=active-backup and fail_over_mac=follow are not functioning due to a race when activating network profiles. activate_nm_connections() attempts to activate all its generated profiles that are not currently in the "active" state. As autoconnect-slaves is set, once br-ex is activated the bond and all its slaves are automatically activated. Their state is set to "activating" until they become active. The "activating" state is not tested for therefor some of the subordinate profiles maybe activated multiple times causing a race in the bonding driver and incorrectly configuring the bond.

…ion." This reverts commit 50817d1.
With bonded network configurations slaves interfaces will be implicitly activate after br-ex is explicitly activated. This implicit activation can take a number of seconds, during this time if one and only one slave is explicitly activated the bonding driver may set the same MAC address to both slaves. This will cause the bond to fail when option fail_over_mac=follow is set. This change gives bond slaves up to 5 seconds to implicitly activate preventing the issue.
