| * | ipv6: add option to drop unicast encapsulated in L2 multicast | Johannes Berg | 2017-11-18 | 1 | -0/+10 |
| | | | | | | | | | | | | | | | | 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 IPv6 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.

| * | ipv6: Make MLD packets to only be processed locally | Angga | 2016-08-26 | 1 | -3/+3 |
| | | | | | | | | | | | | | | | | | | [ Upstream commit 4c938d22c88a9ddccc8c55a85e0430e9c62b1ac5 ] Before commit daad151263cf ("ipv6: Make ipv6_is_mld() inline and use it from ip6_mc_input().") MLD packets were only processed locally. After the change, a copy of MLD packet goes through ip6_mr_input, causing MRT6MSG_NOCACHE message to be generated to user space. Make MLD packet only processed locally. Fixes: daad151263cf ("ipv6: Make ipv6_is_mld() inline and use it from ip6_mc_input().")
