I have been writing an ebpf golang program that tries to access struct task_struct from #include<linux/sched.h>.
I am on Debian GNU/Linux 11 (bullseye) with kernel version 5.10.0-19 and architecture x86_64. The header is found in the package linux-headers-5.10.0-19-common.
I am trying to include the correct paths to compile. My current command is as follows (CLANG_INCLUDE contains a few headers specific to my ebpf program):
$(EBPF_BINARY): $(EBPF_SOURCE)
$(CLANG) -D __KERNEL__ -D __BPF_TRACING__ \
$(CLANG_INCLUDE) \
--include /usr/src/linux-headers-5.10.0-19-common/include/asm-generic/atomic64.h \
-I /usr/src/linux-headers-5.10.0-19-common/include \
-I /usr/src/linux-headers-5.10.0-19-amd64/include \
-I /usr/src/linux-headers-5.10.0-19-common/arch/x86/include/ \
-I /usr/src/linux-headers-5.10.0-19-common/arch/x86/include/uapi \
-I /usr/src/linux-headers-5.10.0-19-amd64/arch/x86/include/generated/uapi \
-I /usr/src/linux-headers-5.10.0-19-amd64/include/generated/uapi \
-I /usr/src/linux-headers-5.10.0-19-amd64/arch/x86/include/generated \
-O2 -target bpf -c $^ -o $@
It shows a handful of errors:
clang -D __KERNEL__ -D __BPF_TRACING__ \
-I headers \
--include /usr/src/linux-headers-5.10.0-19-common/include/asm-generic/atomic64.h \
