Detailed Description

struct sockaddr_nm - The sockaddr structure for NET_MGMT sockets

Similar concepts are used as in Linux AF_NETLINK. The NETLINK name is not used in order to avoid confusion between Zephyr and Linux as the implementations are different.

The socket domain (address family) is AF_NET_MGMT, and the type of socket is either SOCK_RAW or SOCK_DGRAM, because this is a datagram-oriented service.

The protocol (protocol type) selects for which feature the socket is used.

When used with bind(), the nm_pid field of the sockaddr_nm can be filled with the calling thread' own id. The nm_pid serves here as the local address of this net_mgmt socket. The application is responsible for picking a unique integer value to fill in nm_pid.

Field Documentation

◆ nm_family

sa_family_t sockaddr_nm::nm_family

AF_NET_MGMT address family.

◆ nm_ifindex

int sockaddr_nm::nm_ifindex

Network interface related to this address.

◆ nm_mask

uint32_t sockaddr_nm::nm_mask

net_mgmt mask

◆ nm_pid

uintptr_t sockaddr_nm::nm_pid

Thread id or similar that is used to separate the different sockets.

Application can decide how the pid is constructed.
