            Bug ID: 27403
           Summary: aarch64: tlsdesc htab is not freed on dlclose
           Product: glibc
           Version: 2.33
            Status: NEW
          Severity: normal
          Priority: P2
         Component: dynamic-link
          Assignee: unassigned at sourceware dot org
          Reporter: nsz at gcc dot gnu.org
  Target Milestone: ---

aarch64 has a dl_unmap that properly frees per module
tlsdesc data but DL_UNMAP_IS_SPECIAL is not defined
so the default cleanup is used.

this means the hash table for tls descriptors is leaked
on dlclose.

    aarch64: free tlsdesc data on dlclose [BZ #27403]

    DL_UNMAP_IS_SPECIAL and DL_UNMAP were not defined. The definitions are
    now copied from arm, since the same is needed on aarch64. The cleanup
    of tlsdesc data is handled by the custom _dl_unmap.

    Fixes bug 27403.
