Yes, agreed, IEEE 802.11 interfaces should not be changed into "monitor mode" that receives all frames on the channel for normal bridging. Whether the "promiscuous mode" is really a suitable name for this mode is another question, though, since there are more ways to be promiscuous in wireless networks than wired.. ;-) > Please let me know what you think of this patch and whether it could interfere > with any functionality. Its desired goal sounds reasonable. I'm not sure whether dev->ieee80211_ptr is guaranteed to be set with all drivers and all configurations, though. Anyway, this should not break normal IEEE 802.11 bridging cases. > + * 802.11 interfaces working as Access Points do not need to be set to > + * promiscuous mode for bridging, as every frame is addressed to them. > + * > + * Bridging of 802.11 interfaces which are not in AP mode is not > + * supported. This is not strictly speaking correct. 4-address frame format (WDS) can be used in other (non-AP) modes, too. Anyway, they do not require the interface to be in promiscuous mode since addr1 of the frames is the unicast address of the receiving device regardless of the original destination address. -- Jouni Malinen PGP id EFC895FA -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
