[Bug libc/34539] New: ptrace PTRACE_POKEUSER vs PTRACE_POKEUSR

https://sourceware.org/bugzilla/show_bug.cgi?id=34539

            Bug ID: 34539
           Summary: ptrace PTRACE_POKEUSER vs PTRACE_POKEUSR
           Product: glibc
           Version: unspecified
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: libc
          Assignee: unassigned at sourceware dot org
          Reporter: ndesaulniers at google dot com

  Target Milestone: ---

I was refactoring code in lldb and hit a breakage that I had to squint at for a
bit.

I don't know if it's a bug in glibc, per se, but I noticed that in my kernel
headers:

/usr/include/linux/ptrace.h#L17: #define PTRACE_POKEUSR       6

but in my glibc headers:

/usr/include/x86_64-linux-gnu/sys/ptrace.h#L58: PTRACE_POKEUSER = 6,


I don't know if the glibc enum variants' identifiers are supposed to match the
kernel identifiers, but it looks like there's a subtle difference in spelling
between the two: PTRACE_POKEUSR vs PTRACE_POKEUSER.

In the case of lldb, it was using PTRACE_POKEUSER (glibc), but I think I should
change it to PTRACE_POKEUSR (linux kernel).
