2016-12-08bpf: xdp: Allow head adjustment in XDP progMartin KaFai Lau1-0/+4
This patch allows XDP prog to extend/remove the packet data at the head (like adding or removing header). It is done by adding a new XDP helper bpf_xdp_adjust_head(). It also renames bpf_helper_changes_skb_data() to bpf_helper_changes_pkt_data() to better reflect that XDP prog does not work on skb. This patch adds one "xdp_adjust_head" bit to bpf_prog for the XDP-capable driver to check if the XDP prog requires bpf_xdp_adjust_head() support. The driver can then decide to error out during XDP_SETUP_PROG.

2016-12-02bpf, xdp: drop rcu_read_lock from bpf_prog_run_xdp and move to callerDaniel Borkmann1-1/+1
After 326fe02d1ed6 ("net/mlx4_en: protect ring->xdp_prog with rcu_read_lock"), the rcu_read_lock() in bpf_prog_run_xdp() is superfluous, since callers need to hold rcu_read_lock() already to make sure BPF program doesn't get released in the background. Thus, drop it from bpf_prog_run_xdp(), as it can otherwise be misleading. Still keeping the bpf_prog_run_xdp() is useful as it allows for grepping in XDP supported drivers and to keep the typecheck on the context intact. For mlx4, this means we don't have a double rcu_read_lock() anymore. nfp can just make use of bpf_prog_run_xdp(), too. For qede, just move rcu_read_lock() out of the helper. When the driver gets atomic replace support, this will move to call-sites eventually. mlx5 needs actual fixing as it has the same issue as described already in 326fe02d1ed6 ("net/mlx4_en: protect ring->xdp_prog with rcu_read_lock"), that is, we're under RCU bh at this time, BPF programs are released via call_rcu(), and call_rcu() != call_rcu_bh(), so we need to properly mark read side as programs can get xchg()'ed in mlx5e_xdp_set() without queue reset.

2016-11-16netronome: don't access real_num_rx_queues directlyArnd Bergmann1-8/+6
The netdev->real_num_rx_queues setting is only available if CONFIG_SYSFS is enabled, so we now get a build failure when that is turned off: netronome/nfp/nfp_net_common.c: In function 'nfp_net_ring_swap_enable': netronome/nfp/nfp_net_common.c:2489:18: error: 'struct net_device' has no member named 'real_num_rx_queues'; did you mean 'real_num_tx_queues'? As far as I can tell, the check here is only used as an optimization that we can skip in order to fix the compilation.
