Just remove the patch 1 and keep adding needs_root in patch 2?

If you haven't added it to any test which would have needs_device or
mount_device, then v2 can be kept.
But process_vm_readv02 works for me (on master, on Debian) without root:
$ ./process_vm_readv02
tst_test.c:1526: TINFO: Timeout per run is 0h 00m 30s
process_vm_readv02.c:32: TINFO: child 0: memory allocated and initialized
process_vm_readv02.c:49: TINFO: child 1: reading string from same memory location
process_vm_readv02.c:61: TPASS: expected string received
Summary:
passed 1
failed 0
broken 0
skipped 0
warnings 0
Also process_vm_readv03, process_vm_writev02 (I stopped checking now).
Why you need it?
Kind regards,
Petr

Because of the tests bind06/msgget03/sendto03/setsockopt0[5-9]/swapon01 don't reference to
mount device or different outcome on kinds of kernel versions, should I resubmit a new patch to fix them first?
In fact, I have no a system with kernel version 4.15 that can trace what has happened for tests process_vm_* now.

My system is base on kernel version 4.15.0 and glibc 2.27.
When I run the test on the kernel version 6.0 system with non-root, it is passed.

OK, your system is Alpine (it can shorten our discussion next time if you report
you have problems on musl - i.e. which kernel and libc + versions you use).
Well, we should first check if this is not a bug in musl or Alpine before
requiring root.
It'd be interesting to know whether tools/testing/selftests/vm/memfd_secret.c
and tools/testing/selftests/x86/test_vsyscall.c also require root.

Before I wrote to musl ML and/or ptrace maintainer, anybody knows why
__NR_process_vm_readv requires root? Looking at kernel mm/process_vm_access.c,
process_vm_rw() calls process_vm_rw_core(), where:
mm = mm_access(task, PTRACE_MODE_ATTACH_REALCREDS);
if (!mm || IS_ERR(mm)) {
rc = IS_ERR(mm) ? PTR_ERR(mm) : -ESRCH;
/*
* Explicitly map EACCES to EPERM as EPERM is a more
* appropriate error code for process_vw_readv/writev
*/
if (rc == -EACCES)
rc = -EPERM;
goto put_task_struct;
}
=> kernel/fork.c
struct mm_struct *mm_access(struct task_struct *task, unsigned int mode)
{
...
mm = get_task_mm(task);
if (mm && mm != current->mm &&
!ptrace_may_access(task, mode)) {
mmput(mm);
mm = ERR_PTR(-EACCES);
}
=> kernel/ptrace.c
/* Returns 0 on success, -errno on denial. */
static int __ptrace_may_access(struct task_struct *task, unsigned int mode)
{
const struct cred *cred = current_cred(), *tcred;
struct mm_struct *mm;
kuid_t caller_uid;
kgid_t caller_gid;
if (!(mode & PTRACE_MODE_FSCREDS) == !(mode & PTRACE_MODE_REALCREDS)) {
WARN(1, "denying ptrace access check without PTRACE_MODE_*CREDS\n");
return -EPERM;
}
...
rcu_read_unlock();
return -EPERM;
ok:
...
Failing LTP code:
TEST(tst_syscall(__NR_process_vm_readv, pid_alloc, &local, 1UL, &remote,
1UL, 0UL));
if (TST_RET != length)
tst_brk(TBROK, "process_vm_readv: %s", tst_strerrno(-TST_RET));

Ah, b740bfac5 ("msgget03: Set custom queue limit")
causes the need for root. IMHO this one is valid.
I'd suggest to remove needs_root for needs_device and mount_device now
(i.e. send v2).
nit: FYI most of the people use bottom posting on mailing lists, you use top
posting. Combine both makes it hard to follow.

To: ltp
