| H A D | if_tap.c | diff 127003 Sun Mar 14 23:52:00 MST 2004 rwatson Lock down global variables in if_tap (primarily, the tap softc list); add tapmtx, which protects globale variables. Notes: - The EBUSY check in MOD_UNLOAD may be subject to a race. Moving the event handler unregister inside the mutex grab may prevent that race. - Locking of global variables safely is now possible because tapclones is only modified when the module is loading or unloading, thanks to phk's recent chang to clone_setup(). - softc locking to follow. |
