From: Kuniyuki Iwashima <kuniyu@xxxxxxxxxx> [ Upstream commit acfc35cfcee5df419391671ef1a631f43feee4e3 ] Add the same change for ARM64 as done in the commit 9440c4294160 ("x86/syscall: Include asm/ptrace.h in syscall_wrapper header") to make sure all syscalls see 'struct pt_regs' definition and resulted BTF for '__arm64_sys_*(struct pt_regs *regs)' functions point to actual struct. Without this patch, the BPF verifier refuses to load a tracing prog which accesses pt_regs. bpf(BPF_PROG_LOAD, {prog_type=0x1a, ...}, 128) = -1 EACCES With this patch, we can see the correct error, which saves us time in debugging the prog. bpf(BPF_PROG_LOAD, {prog_type=0x1a, ...}, 128) = 4 bpf(BPF_RAW_TRACEPOINT_OPEN, {raw_tracepoint={name=NULL, prog_fd=4}}, 128) = -1 ENOTSUPP Signed-off-by: Kuniyuki Iwashima <kuniyu@xxxxxxxxxx> Acked-by: Andrii Nakryiko <andrii@xxxxxxxxxx> Link: https://lore.kernel.org/r/20221031215728.50389-1-kuniyu@xxxxxxxxxx Signed-off-by: Catalin Marinas <catalin.marinas@xxxxxxx> Signed-off-by: Sasha Levin <sashal@xxxxxxxxxx> --- arch/arm64/include/asm/syscall_wrapper.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/arm64/include/asm/syscall_wrapper.h b/arch/arm64/include/asm/syscall_wrapper.h index b383b4802a7b..d30217c21eff 100644 --- a/arch/arm64/include/asm/syscall_wrapper.h +++ b/arch/arm64/include/asm/syscall_wrapper.h @@ -8,7 +8,7 @@ #ifndef __ASM_SYSCALL_WRAPPER_H #define __ASM_SYSCALL_WRAPPER_H -struct pt_regs; +#include <asm/ptrace.h> #define SC_ARM64_REGS_TO_ARGS(x, ...) \ __MAP(x,__SC_ARGS \ -- 2.35.1
