2022-05-10Merge branch 'bpf: bpf link iterator'Alexei Starovoitov7-157/+261
Dmitrii Dolgov says: ==================== Bpf links seem to be one of the important structures for which no iterator is provided. Such iterator could be useful in those cases when generic 'task/file' is not suitable or better performance is needed. The implementation is mostly copied from prog iterator. This time tests were executed, although I still had to exclude test_bpf_nf (failed to find BTF info for global/extern symbol 'bpf_skb_ct_lookup') -- since it's unrelated, I hope it's a minor issue. Per suggestion from the previous discussion, there is a new patch for converting CHECK to corresponding ASSERT_* macro. Such replacement is done only if the final result would be the same, e.g. CHECK with important-looking custom formatting strings are still in place -- from what I understand ASSERT_* doesn't allow to specify such format. The third small patch fixes what looks like a copy-paste error in the condition checking. ==================== Signed-off-by: Alexei Starovoitov <ast@kernel.org>

2022-05-10Merge branch 'Add source ip in bpf tunnel key'Alexei Starovoitov6-248/+687
Kaixi Fan says: ==================== From: Kaixi Fan <fankaixi.li@bytedance.com> Now bpf code could not set tunnel source ip address of ip tunnel. So it could not support flow based tunnel mode completely. Because flow based tunnel mode could set tunnel source, destination ip address and tunnel key simultaneously. Flow based tunnel is useful for overlay networks. And by configuring tunnel source ip address, user could make their networks more elastic. For example, tunnel source ip could be used to select different egress nic interface for different flows with same tunnel destination ip. Another example, user could choose one of multiple ip address of the egress nic interface as the packet's tunnel source ip. Add tunnel and tunnel source testcases in test_progs. Other types of tunnel testcases would be moved to test_progs step by step in the future. v6: - use libbpf api to attach tc progs and remove some shell commands to reduce test runtime based on Alexei Starovoitov's suggestion v5: - fix some code format errors - use bpf kernel code at namespace at_ns0 to set tunnel metadata v4: - fix subject error of first patch v3: - move vxlan tunnel testcases to test_progs - replace bpf_trace_printk with bpf_printk - rename bpf kernel prog section name to tic v2: - merge vxlan tunnel and tunnel source ip testcases in test_tunnel.sh ==================== Signed-off-by: Alexei Starovoitov <ast@kernel.org>
