Modified Files: src/sys/net: if.c Log Message: Avoid if_dl and if_sadl to be NULL Calling if_deactivate_sadl and then if_sadl_setrefs exposes NULL-ed if_dl and if_sadl to users for a moment. It's harmful because users expect that they're always non-NULL. Fix it. Note that a race condition still remains; if_dl and if_sald aren't updated atomically so a user can see different data from if_dl and if_sadl. Fortunately none uses both if_dl and if_sadl at the same time, so the race condition doesn't hurt nobody for now. (In the first place exposing one data with two ways is problematic?)
