Johannes Berg 7be69c0b9a wext: fix get_wireless_stats locking ... Currently, get_wireless_stats is racy by _design_. This is because it returns a buffer, which needs to be statically allocated since it cannot be freed if it was allocated dynamically. Also, SIOCGIWSTATS and /proc/net/wireless use no common lock, and /proc/net/wireless accesses are not synchronised against each other. This is a design flaw in get_wireless_stats since the beginning. This patch fixes it by wrapping /proc/net/wireless accesses with the RTNL so they are protected against each other and SIOCGIWSTATS. The more correct method of fixing this would be to pass in the buffer instead of returning it and have the caller take care of synchronisation of the buffer, but even then most drivers probably assume that their callback is protected by the RTNL like all other wext callbacks.
