Pablo Neira 8b7c36d810 netlink: fix wrong subscription bitmask to group mapping in ... The subscription bitmask passed via struct sockaddr_nl is converted to the group number when calling the netlink_bind() and netlink_unbind() callbacks. The conversion is however incorrect since bitmask (1 << 0) needs to be mapped to group number 1. Note that you cannot specify the group number 0 (usually known as _NONE) from setsockopt() using NETLINK_ADD_MEMBERSHIP since this is rejected through -EINVAL. This problem became noticeable since 97840cb ("netfilter: nfnetlink: fix insufficient validation in nfnetlink_bind") when binding to bitmask (1 << 0) in ctnetlink.
