bpf: Fix BTF_ID symbol generation collision in tools/

2023-09-15T19:08:27Z

Marcus and Satya reported an issue where BTF_ID macro generates same symbol in separate objects and that breaks final vmlinux link. ld.lld: error: ld-temp.o :14577:1: symbol '__BTF_ID__struct__cgroup__624' is already defined This can be triggered under specific configs when __COUNTER__ happens to be the same for the same symbol in two different translation units, which is already quite unlikely to happen. Add __LINE__ number suffix to make BTF_ID symbol more unique, which is not a complete fix, but it would help for now and meanwhile we can work on better solution as suggested by Andrii.

tools headers UAPI: Copy seccomp.h to be able to build 'perf bench' in older systems

2023-09-13T11:48:48Z

The new 'perf bench' for sched-seccomp-notify uses defines and types not available in older systems where we want to have perf available, so grab a copy of this UAPI from the kernel sources to allow that. This will be checked in the future for drift from the original when we build the perf tool, that will warn when that happens like: make: Entering directory '/var/home/acme/git/perf-tools/tools/perf' BUILD: Doing 'make -j32' parallel build Warning: Kernel ABI header differences: Cc: Adrian Hunter Cc: Andrei Vagin Cc: Ian Rogers Cc: Jiri Olsa Cc: Kees Kook Cc: Namhyung Kim Cc: Peter Zijlstra Link: https://lore.kernel.org/lkml/ZQGhMXtwX7RvV3ya@kernel.org Signed-off-by: Arnaldo Carvalho de Melo

bpf: Clarify error expectations from bpf_clone_redirect

2023-09-11T20:29:19Z

Commit 151e887d8ff9 ("veth: Fixing transmit return status for dropped packets") exposed the fact that bpf_clone_redirect is capable of returning raw NET_XMIT_XXX return codes. This is in the conflict with its UAPI doc which says the following: "0 on success, or a negative error in case of failure." Update the UAPI to reflect the fact that bpf_clone_redirect can return positive error numbers, but don't explicitly define their meaning.
