[ISSUE] Failed to find "enabled" option.

by Xin Long

I found this err in "loadbalance" and "lacp" runner when adding ports. It's caused by trying to set "enabled" option in .port_link_changed() or .port_changed(). When a new port is added, the first 'port changed event' process is earlier than CMD TEAM_CMD_OPTIONS_GET, in this CMD, all the options are synchronized from kernel. It means there's no 'enabled' option yet when calling port_link_changed in the first 'port changed event' process. In lb_event_watch_port_link_changed and lacp_event_watch_port_changed, they call teamd_port_check_enable to set 'enabled' option. this err is triggered. I'm not sure why teamd_port_check_enable needs to check if 'enabled' option exists. I checked the ab's .port_link_changed(), it just sets it by calling team_set_port_enabled(), instead of checking 'enabled' option first. can we just use team_set_port_enabled to set it directly in .port(_link)_changed OR improve teamd_port_check_enable to avoid this err ? Thanks.

teamd interaction with linux kernel user_carrier_enabled

by George Wilkie

Hi, like to get your thoughts on this issue we are running into. Initially, running the lacp runner in teamd. This sends carrier changes to the kernel. Kernel sets "user_carrier_enabled" which blocks its normal carrier checks. Then change teamd runner from lacp to loadbalance. When lacp runner exits, carrier is set to down in kernel. lacp and loadbalance runners both use same kernel mode "loadbalance", so starting loadbalance runner does not change kernel mode. Kernel still has "user_carrier_enabled" and team interface stays down due to NO_CARRIER. It seems the only way to clear kernel "user_carrier_enabled" is to change the mode. Should there be a new option that teamd can use to tell kernel to clear "user_carrier_enabled" when lacp runner terminates? Or any other suggestion? Thanks.

[PATCH] teamd: check port link_up when a port is added with loadbalance runner

by Xin Long

In loadbalance runner, when a port with no carrier is added, the port's 'enabled' option should have been set false, so that it can change to other ports to send the packet. This patch is to fix it by checking it in lb's watch_ops .port_added().
