[RFC PATCH net-next 00/12] XDP batching for TUN/vhost_net

Hi all: We do not support XDP batching for TUN since it can only receive one packet a time from vhost_net. This series tries to remove this limitation by: - introduce a TUN specific msg_control that can hold a pointer to an array of XDP buffs - try copy and build XDP buff in vhost_net - store

[PATCH 0/3] bpf: add boot parameters for sysctl knobs

Hello. This patch set adds ability to set default values for kernel.unprivileged_bpf_disable, net.core.bpf_jit_harden, net.core.bpf_jit_kallsyms sysctl knobs as well as option to override them via a boot-time kernel parameter. Eugene Syromiatnikov (3): bpf: add ability to configure

This patches implement a TUN specific msg_control: #define TUN_MSG_UBUF 1 #define TUN_MSG_PTR 2 struct tun_msg_ctl { int type; void *ptr; }; The first supported type is ubuf which is already used by vhost_net zerocopy code. The second is XDP buff, which allows vhost_net to pass
