Re: [PATCH] Check multiple NT_GNU_PROPERTY_TYPE_0 notes [BZ #23509]

_dl_process_cet_property_note is called on on each PT_NOTE segment.
We must keep searching until we found a PT_NOTE segment with a
NT_GNU_PROPERTY_TYPE_0 note:

   /* Skip if we have seen a NT_GNU_PROPERTY_TYPE_0 note before.  */
   if (l->l_cet != lc_unknown)
     return;
...
What if there are different segments, each one with its own NT_GNU_PROPERTY_TYPE_0? Wouldn't that point to lack of linker support, too? So that CET needs to be disabled? 

Thanks,
