            Bug ID: 18870
           Summary: sem_open.c fails to compile with missing symbol
                    FUTEX_SHARED
           Product: glibc
           Version: 2.22
            Status: NEW
          Severity: normal
          Priority: P2
         Component: build
          Assignee: unassigned at sourceware dot org
          Reporter: bneumeier at gmail dot com
                CC: carlos at redhat dot com
  Target Milestone: ---

Created attachment 8551
  --> https://sourceware.org/bugzilla/attachment.cgi?id=8551&action=edit
Add missing include directive.

In 2.22 and master, when doing a x86_64-pc-linux-gnu to sparc-pc-linux-gnu
cross-toolchain build, sem_open.c fails to compile because it can't find
FUTEX_SHARED. It looks to me like an include directive got missed.

The attached fixes it for me on 2.22.

This was already approved in 
<https://sourceware.org/ml/libc-alpha/2015-08/msg00256.html>.  If you 
don't have write access, reply to David Miller's message to ask him to 
commit it (to master and 2.22 branch) and to include [BZ #18870] in the 
ChangeLog entry, and 18870 in the list of fixed bugs in NEWS, when doing 
so.

Thanks for the guidance, Joseph!

I only belatedly read through the contribution checklist wiki page and created
this bugzilla ticket because it said I ought to. (And the wiki page doesn't
talk about what to do once a patch is reviewed and accepted, so your
instructions here are especially valuable in that regard.)

    Always enable pointer guard [BZ #18928]

    Honoring the LD_POINTER_GUARD environment variable in AT_SECURE mode
    has security implications.  This commit enables pointer guard
    unconditionally, and the environment variable is now ignored.

            [BZ #18928]
            * sysdeps/generic/ldsodefs.h (struct rtld_global_ro): Remove
            _dl_pointer_guard member.
            * elf/rtld.c (_rtld_global_ro): Remove _dl_pointer_guard
            initializer.
            (security_init): Always set up pointer guard.
            (process_envvars): Do not process LD_POINTER_GUARD.
