The data can be accessed from sysctl, ioctl, interface watchdog (if_slowtimo) and interrupt handlers. We need to protect the data against parallel accesses from them. Currently the mutex is applied to some drivers, we need to apply it to all drivers in the future. Note that the mutex is adaptive one for ease of implementation but some drivers access the data in interrupt context so we cannot apply the mutex to every drivers as is. We have two options: one is to replace the mutex with a spin one, which requires some additional works (see ether_multicast_sysctl), and the other is to modify the drivers to access the data not in interrupt context somehow. |
