Subject: [PATCH AUTOSEL 5.10 16/18] arm64/syscall: Include asm/ptrace.h in syscall_wrapper header.
Date: Fri, 18 Nov 2022 21:14:57 -0500 [thread overview]
Message-ID: <20221119021459.1775052-16-sashal@kernel.org> (raw)
In-Reply-To: <20221119021459.1775052-1-sashal@kernel.org>
From: Kuniyuki Iwashima <kuniyu@amazon.com>
[ 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
