Vincent Li	64d12aacc8	ebpf: Update eBPF map to BTF defined map legacy map definition is removed from libbpf1.0+. update the legacy map definition to BTF defined map. Distros with < libbpf1.0 (0.5, 0.6, 0.7, 0.8) bpf_helpers.h support BTF map definition, this change does not break old libbpf and support new libpbf1.0+.

Jesper Dangaard Brouer	7906c521cd	ebpf: take clang -target bpf include issue of stdint.h into account This patch prepares code before enabling the clang -target bpf. The clang compiler does not like #include <stdint.h> when using '-target bpf' it will fail with: fatal error: 'gnu/stubs-32.h' file not found This is because using clang -target bpf, then clang will have '__bpf__' defined instead of '__x86_64__' hence the gnu/stubs-32.h include attempt as /usr/include/gnu/stubs.h contains, on x86_64: #if !defined __x86_64__ # include <gnu/stubs-32.h> #endif #if defined __x86_64__ && defined __LP64__ # include <gnu/stubs-64.h> #endif #if defined __x86_64__ && defined __ILP32__ # include <gnu/stubs-x32.h> #endif This can be worked around by installing the 32-bit version of glibc-devel.i686 on your distribution. But the BPF programs does not really need to include stdint.h, if converting: uint64_t -> __u64 uint32_t -> __u32 uint16_t -> __u16 uint8_t -> __u8 This patch does this type syntax conversion. The build of a ebpf files had an issue for system like Debian because they don't have a asm/types.h in the include path if the architecture is not defined which is the case due to target bpf. This results in: clang-5.0 -Wall -Iinclude -O2 \ -D__KERNEL__ -D__ASM_SYSREG_H \ -target bpf -S -emit-llvm vlan_filter.c -o vlan_filter.ll In file included from vlan_filter.c:19: In file included from include/linux/bpf.h:11: /usr/include/linux/types.h:5:10: fatal error: 'asm/types.h' file not found #include <asm/types.h> ^~~~~~~~~~~~~ 1 error generated. Makefile:523: recipe for target 'vlan_filter.bpf' failed This patch fixes the issue by adding a include path setting the architecture to the one of the builder.
