-Subject: [PATCH] sh: Fix building with gcc5/6
-
-Build glibc for sh4-unknown-linux-gnu currently fails if one's
-using GCC5/6: in dl-conflict.c, the elf_machine_rela() function
-is called with NULL as its 3rd argument, sym. The implementation
-of that function in sysdeps/sh/dl-machine.h dereferences that pointer:
-
-const Elf32_Sym *const refsym = sym;
-...
-if (map == &GL(dl_rtld_map))
-  value -= map->l_addr + refsym->st_value + reloc->r_addend;
-
-GCC discovers a null pointer dereference, and in accordance with
--fdelete-null-pointer-checks (which is enabled in -O2) replaces this
-code with a trap - which, as SH does not implement a trap pattern in
-GCC, evaluates to an abort() call. This abort() call pulls many more
-objects from libc_nonshared.a, eventually resulting in link failure
-due to multiple definitions for a number of symbols.
-
-As far as I see, the conditional before this code is always false in
-rtld: _dl_resolve_conflicts() is called with main_map as the first
-argument, not GL(_dl_rtld_map), but since that call is in yet another
-compilation unit, GCC does not know about it. Patch that wraps this
-conditional into !defined RESOLVE_CONFLICT_FIND_MAP attached.
-
-	* sysdeps/sh/dl-machine.h (elf_machine_rela): The condition
-	in R_SH_DIR32 case is always false when inlined from
-	dl-conflict.c. Ifdef out to prevent GCC from insertin an
-	abort() call.

-Subject: [PATCH] CVE-2017-1000366: Ignore LD_LIBRARY_PATH for AT_SECURE=1
- programs [BZ #21624]
-
-LD_LIBRARY_PATH can only be used to reorder system search paths, which
-is not useful functionality.
-
-This makes an exploitable unbounded alloca in _dl_init_paths unreachable
-for AT_SECURE=1 programs.

-Since commit d957c4d3fa48d685ff2726c605c988127ef99395 (i386: Compile
-rtld-*.os with -mno-sse -mno-mmx -mfpmath=387), vector intrinsics can
-no longer be used in ld.so, even if the compiled code never makes it
-into the final ld.so link.  This commit adds the missing IS_IN (libc)
-guard to the SSE 4.2 strcspn implementation, so that it can be used from
-ld.so in the future.

-    Build divdi3 only for architecture that required it
-    
-    As noted in [1], divdi3 object is only exported in a handful ABIs
-    (i386, m68k, powerpc32, s390-32, and ia64), however it is built
-    for all current architectures regardless.
-    
-    This patch refact the make rules for this object to so only the
-    aforementioned architectures that actually require it builds it.
-    
-    Also, to avoid internal PLT calls to the exported symbol from the
-    module, glibc uses an internal header (symbol-hacks.h) which is
-    unrequired (and in fact breaks the build for architectures that
-    intend to get symbol definitions from libgcc.a).  The patch also
-    changes it to create its own header (divdi3-symbol-hacks.h) and
-    adjust the architectures that require it accordingly.
-    
-    I checked the build/check (with run-built-tests=no) on the
-    following architectures (which I think must cover all supported
-    ABI/builds) using GCC 6.3:
-    
-    aarch64-linux-gnu
-    alpha-linux-gnu
-    arm-linux-gnueabihf
-    hppa-linux-gnu
-    ia64-linux-gnu
-    m68k-linux-gnu
-    microblaze-linux-gnu
-    mips64-n32-linux-gnu
-    mips-linux-gnu
-    mips64-linux-gnu
-    nios2-linux-gnu
-    powerpc-linux-gnu
-    powerpc-linux-gnu-power4
-    powerpc64-linux-gnu
-    powerpc64le-linux-gnu
-    s390x-linux-gnu
-    s390-linux-gnu
-    sh4-linux-gnu
-    sh4-linux-gnu-soft
-    sparc64-linux-gnu
-    sparcv9-linux-gnu
-    tilegx-linux-gnu
-    tilegx-linux-gnu-32
-    tilepro-linux-gnu
-    x86_64-linux-gnu
-    x86_64-linux-gnu-x32
-    i686-linux-gnu
-    
-    I only saw one regression on sparcv9-linux-gnu (extra PLT call to
-    .udiv) which I address in next patch in the set.  It also correctly
-    build SH with GCC 7.0.1 (without any regression from c89721e25d).
