| * | ipv4: add option to drop gratuitous ARP packets | Johannes Berg | 2017-11-18 | 1 | -0/+1 |
| | | | | | | | | | | | | | | In certain 802.11 wireless deployments, there will be ARP proxies that use knowledge of the network to correctly answer requests. To prevent gratuitous ARP frames on the shared medium from being a problem, on such deployments wireless needs to drop them. Enable this by providing an option called "drop_gratuitous_arp".

| * | ipv4: add option to drop unicast encapsulated in L2 multicast | Johannes Berg | 2017-11-18 | 1 | -0/+1 |
| | | | | | | | | | | | | | | | | | | | In order to solve a problem with 802.11, the so-called hole-196 attack, add an option (sysctl) called "drop_unicast_in_l2_multicast" which, if enabled, causes the stack to drop IPv4 unicast packets encapsulated in link-layer multi- or broadcast frames. Such frames can (as an attack) be created by any member of the same wireless network and transmitted as valid encrypted frames since the symmetric key for broadcast frames is shared between all stations. Additionally, enabling this option provides compliance with a SHOULD clause of RFC 1122.
