> This patch adds getsockopt(SOL_NETLINK, NETLINK_LIST_MEMBERSHIPS) to > retrieve all groups a socket is a member of. Currently, we have to use > getsockname() and look at the nl.nl_groups bitmask. However, this mask is > limited to 32 groups. Hence, similar to NETLINK_ADD_MEMBERSHIP and > NETLINK_DROP_MEMBERSHIP, this adds a separate sockopt to manager higher > groups IDs than 32. > > This new NETLINK_LIST_MEMBERSHIPS option takes a pointer to __u32 and the > size of the array. The array is filled with the full membership-set of the > socket, and the required array size is returned in optlen. Hence, > user-space can retry with a properly sized array in case it was too small. > > Signed-off-by: David Herrmann <dh.herrm...@gmail.com> This does not apply to the current net-next tree, please respin. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
