            Bug ID: 17381
           Summary: Access TLS address space of inferior's threads from
                    gdb
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: nptl
          Assignee: unassigned at sourceware dot org
          Reporter: siddhesh at redhat dot com
                CC: drepper.fsp at gmail dot com

Currently there is no standard way to access the TLS area of an arbitrary
thread from within gdb without intimate knowledge about the layout of the TLS
address space or the module id for dynamic tls, both of which could change.  It
would be good to have a standard, supported interface in glibc that allows the
debugger (and any diagnostic tool for that matter, like valgrind, asan, etc.)
to inspect the TLS area for arbitrary threads in the attached process.

For further information, see [1].
