Currently, dumping almost all BTFs specified by id requires using the -B option to pass the base BTF. For kernel module BTFs the vmlinux BTF sysfs path should work. This patch simplifies dumping by ID usage by loading vmlinux BTF from sysfs as base, if base BTF was not specified and the ID corresponds to a kernel module BTF.

Alexis Lothoré says: ==================== Hello, this is the v3 of test_tc_tunnel conversion into test_progs framework. This new revision: - fixes a few issues spotted by the bot reviewer - removes any test ensuring connection failure (and so depending on a timout) to keep the execution time reasonable test_tc_tunnel.sh tests a variety of tunnels based on BPF: packets are encapsulated by a BPF program on the client egress. We then check that those packets can be decapsulated on server ingress side, either thanks to kernel-based or BPF-based decapsulation. Those tests are run thanks to two veths in two dedicated namespaces. - patches 1 and 2 are preparatory patches - patch 3 introduce tc_tunnel test into test_progs - patch 4 gets rid of the test_tc_tunnel.sh script The new test has been executed both in some x86 local qemu machine, as well as in CI: # ./test_progs -a tc_tunnel #454/1 tc_tunnel/ipip_none:OK #454/2 tc_tunnel/ipip6_none:OK #454/3 tc_tunnel/ip6tnl_none:OK #454/4 tc_tunnel/sit_none:OK #454/5 tc_tunnel/vxlan_eth:OK #454/6 tc_tunnel/ip6vxlan_eth:OK #454/7 tc_tunnel/gre_none:OK #454/8 tc_tunnel/gre_eth:OK #454/9 tc_tunnel/gre_mpls:OK #454/10 tc_tunnel/ip6gre_none:OK #454/11 tc_tunnel/ip6gre_eth:OK #454/12 tc_tunnel/ip6gre_mpls:OK #454/13 tc_tunnel/udp_none:OK #454/14 tc_tunnel/udp_eth:OK #454/15 tc_tunnel/udp_mpls:OK #454/16 tc_tunnel/ip6udp_none:OK #454/17 tc_tunnel/ip6udp_eth:OK #454/18 tc_tunnel/ip6udp_mpls:OK #454 tc_tunnel:OK Summary: 1/18 PASSED, 0 SKIPPED, 0 FAILED ==================== Link: https://patch.msgid.link/20251027-tc_tunnel-v3-0-505c12019f9d@bootlin.com Signed-off-by: Martin KaFai Lau <martin.lau@kernel.org>
