This series has fixes when running reuseport's bpf_prog for udp lookup.
If there is reuseport's bpf_prog, the common issue is the reuseport code
path expects skb->data pointing to the transport header (udphdr here).
A couple of commits broke this expectation. The issue is specific
to running bpf_prog, so bpf tag is used for this series.
Please refer to the individual commit message for details.
Martin KaFai Lau (2):
bpf: udp: ipv6: Avoid running reuseport's bpf_prog from __udp6_lib_err
bpf: udp: Avoid calling reuseport's bpf_prog from udp_gro

For example, the icmpv6 toobig(type=2). __udp6_lib_lookup() is then called which may call reuseport_select_sock(). reuseport_select_sock() will call into a bpf_prog (if there is one). reuseport_select_sock() is expecting the skb->data pointing to the transport header (udphdr in this case). For example, run_bpf_filter() is pulling the transport header. However, in the __udp6_lib_err() path, the skb->data is pointing to the ipv6hdr instead of the udphdr. One option is to pull and push the ipv6hdr in __udp6_lib_err(). Instead of doing this, this patch follows how the original commit 538950a1b752 ("soreuseport: setsockopt SO_ATTACH_REUSEPORT_[CE]BPF") was done in IPv4, which has passed a NULL skb pointer to reuseport_select_sock().

The last arg of __udp4_lib_lookup() is skb. __udp4_lib_lookup_skb(), which is not changed in this patch, is still calling __udp4_lib_lookup() with a skb and the skb is used by the reuseport's bpf_prog.
