net: netdev netlink api to bind dma-buf to a net device

2024-09-12T03:44:31Z

API takes the dma-buf fd as input, and binds it to the netdevice. The user can specify the rx queues to bind the dma-buf to.

bpf/bpf_get,set_sockopt: add option to set TCP-BPF sock ops flags

2024-08-08T23:52:43Z

Currently the only opportunity to set sock ops flags dictating which callbacks fire for a socket is from within a TCP-BPF sockops program. This is problematic if the connection is already set up as there is no further chance to specify callbacks for that socket. Add TCP_BPF_SOCK_OPS_CB_FLAGS to bpf_setsockopt() and bpf_getsockopt() to allow users to specify callbacks later, either via an iterator over sockets or via a socket-specific program triggered by a setsockopt() on the socket. Previous discussion on this here [1].
