Previously, there was an assumption that uprobed function is +always in the first executable region, which is not always the case +(libbpf CI hits this case now). So get_base_addr() approach in isolation +doesn't work anymore. So teach get_uprobe_offset() to determine correct +memory mapping and calculate uprobe offset correctly. + +While at it, I merged together two implementations of +get_uprobe_offset() helper, moving powerpc64-specific logic inside (had +to add extra {} block to avoid unused variable error for insn). + +Also ensured that uprobed functions are never inlined, but are still +static (and thus local to each selftest), by using a no-op asm volatile +block internally. I didn't want to keep them global __weak, because some +tests use uprobe's ref counter offset (to test USDT-like logic) which is +not compatible with non-refcounted uprobe. So it's nicer to have each +test uprobe target local to the file and guaranteed to not be inlined or +skipped by the compiler (which can happen with static functions, +especially if compiling selftests with -O2). + +Signed-off-by: Andrii Nakryiko +Link: https://lore.kernel.org/r/20220126193058.3390292-1-andrii@kernel.org +Signed-off-by: Alexei Starovoitov +--- + .../selftests/bpf/benchs/bench_trigger.c | 6 +- + .../selftests/bpf/prog_tests/attach_probe.c | 18 +++-- + .../selftests/bpf/prog_tests/bpf_cookie.c | 16 +++-- + .../selftests/bpf/prog_tests/task_pt_regs.c | 16 +++-- + tools/testing/selftests/bpf/trace_helpers.c | 70 ++++++++----------- + tools/testing/selftests/bpf/trace_helpers.h | 3 +- + 6 files changed, 63 insertions(+), 66 deletions(-) + +diff --git a/tools/testing/selftests/bpf/benchs/bench_trigger.c b/tools/testing/selftests/bpf/benchs/bench_trigger.c +index 7f957c55a3ca..0c481de2833d 100644 +--- a/tools/testing/selftests/bpf/benchs/bench_trigger.c ++++ b/tools/testing/selftests/bpf/benchs/bench_trigger.c +@@ -154,7 +154,6 @@ static void *uprobe_producer_without_nop(void *input) + static void usetup(bool use_retprobe, bool use_nop) + { + size_t uprobe_offset;

For example, $ mount -t bpf bpffs /sys/fs/bpf bpf rw,relatime 0 0 bpffs /sys/fs/bpf bpf rw,relatime 0 0 bpffs /sys/fs/bpf bpf rw,relatime 0 0 bpffs /sys/fs/bpf bpf rw,relatime 0 0 ... That was casued by a buggy user script which didn't check the mount point correctly before mounting bpffs. But it also drives us to think more about if it is okay to allow mounting bpffs on the same mount point multiple times. After investigation we get the conclusion that it is bad to allow that behavior, because it can cause unexpected issues, for example it can break bpftool, which depends on the mount point to get the pinned files. Below is the test case wrt bpftool. First, let's mount bpffs on /var/run/ltcp/bpf multiple times. $ mount -t bpf bpffs on /run/ltcp/bpf type bpf (rw,relatime) bpffs on /run/ltcp/bpf type bpf (rw,relatime) bpffs on /run/ltcp/bpf type bpf (rw,relatime) After pinning some bpf progs on this mount point, let's check the pinned files with bpftool, $ bpftool prog list -f 87: sock_ops name bpf_sockmap tag a04f5eef06a7f555 gpl loaded_at 2022-02-23T16:27:38+0800 uid 0 xlated 16B jited 15B memlock 4096B pinned /run/ltcp/bpf/bpf_sockmap pinned /run/ltcp/bpf/bpf_sockmap pinned /run/ltcp/bpf/bpf_sockmap btf_id 243 89: sk_msg name bpf_redir_proxy tag 57cd311f2e27366b gpl loaded_at 2022-02-23T16:27:38+0800 uid 0 xlated 16B jited 18B memlock 4096B pinned /run/ltcp/bpf/bpf_redir_proxy pinned /run/ltcp/bpf/bpf_redir_proxy pinned /run/ltcp/bpf/bpf_redir_proxy btf_id 244 The same pinned file will be showed multiple times. Finnally after mounting bpffs on the same mount point again, we can't get the pinnned files via bpftool, $ bpftool prog list -f 87: sock_ops name bpf_sockmap tag a04f5eef06a7f555 gpl loaded_at 2022-02-23T16:27:38+0800 uid 0 xlated 16B jited 15B memlock 4096B btf_id 243 89: sk_msg name bpf_redir_proxy tag 57cd311f2e27366b gpl loaded_at 2022-02-23T16:27:38+0800 uid 0 xlated 16B jited 18B memlock 4096B btf_id 244 We should better refuse to mount bpffs on the same mount point. Before making this change, I also checked why it is allowed in the first place. The related commits are commit e27f4a942a0e ("bpf: Use mount_nodev not mount_ns to mount the bpf filesystem") and commit b2197755b263 ("bpf: add support for persistent maps/progs"). Unfortunately they didn't explain why it is allowed. But there should be no use case which requires to mount bpffs on a same mount point multiple times, so let's just refuse it.
