Re: Can only connect to RMS gateway once

This isn't a final solution but the problem is in:

 sock_set_flag(sk, SOCK_DESTROY);

in routine ax25_release() in file net/ax25/af_ax25.c which does what it
is supposed to do in kernel 4.1.21 but NOT in kernels 4.2.8 & above. It
should destroy & free the socket when disconnecting.

For my 4.2.8 kernel If I add this after the sock_set_flag() call in
ax25_release() then the connection is released after disconnect & I can
reconnect again.

    release_sock(sk);
    ax25_disconnect(ax25, 0);
    lock_sock(sk);
    ax25_destroy_socket(ax25);

From the af_ax25 code in the 4.1.21 kernel, it expects sock_set_flag(sk, SOCK_DESTROY); to
 ax25_destroy_socket
 ax25_free_sock
