A title can create a socket with sceNetSocket and then call bind, getsockname, sendto or recvfrom from libkernel, which does not hold that descriptor, so the call failed with EBADF. PPSA06866's RakNet does this, its local server fails to start and the load after difficulty selection never ends. libSceNet now registers these four calls with libkernel, as it does for setsockopt and getsockopt.
