When running as parser interpret BPF_LD | BPF_IMM | BPF_DW instructions as loading CONST_IMM with the value stored in imm. The verifier will continue not recognizing those due to concerns about search space/program complexity increase. Signed-off-by: Jakub Kicinski

XDP user interface confusions

Hi Brenden, I don't quite understand the semantics of the XDP userspace interface. We allow XDP programs to be (unconditionally) exchanged by another program, this avoids taking the link down+up and avoids reallocating RX ring resources (which is great). We have two XDP samples programs in

[PATCH net-next 1/4] ip_tunnel: add collect_md mode to IPIP tunnel

Similar to gre, vxlan, geneve tunnels allow IPIP tunnels to operate in 'collect metadata' mode. bpf_skb_[gs]et_tunnel_key() helpers can make use of it right away. ovs can use it as well in the future (once appropriate ovs-vport abstractions and user apis are added). Note that just like in other

[PATCH net-next 2/4] ip6_tunnel: add collect_md mode to IPv6 tunnels

Similar to gre, vxlan, geneve tunnels allow IPIP6 and IP6IP6 tunnels to operate in 'collect metadata' mode. Unlike ipv4 code here it's possible to reuse ip6_tnl_xmit() function for both collect_md and traditional tunnels. bpf_skb_[gs]et_tunnel_key() helpers and ovs (in the future) are the users.

Hello guys. Some very good people managed to detect there is a problem with some Huawei firmwares and NCM padding. I actually don't think I have the hardware to test btw. On Wed, 14 Sep 2016, Marek Brudka wrote: Sorry Marek - I forwarded this message without asking for your consent. Let me
