Severity: serious
Version: 2.22-7

Hi folks,

Steev has reported some crashing using ldconfig on arm64 systems with
armhf added as a secondary architecture - he's using this config in
Kali, for example.

Working through the problem with him on #debian-arm, I can see that
it's a problem with our/my patch for ARM ABI detection. On older
binaries that predate the new ABI flags in the ELF header, we're still
parsing the ARM attributes. That works fine on armel/armhf, but on
arm64 this code is being built wrongly using native (ELF64)
types. This patch is the obvious fix - enforce using ELF32 types for
all arches.

It seems that we still have some older packages without the ABI flags
attached - libshout3 is one such. :-(

Changes:
 glibc (2.22-8) unstable; urgency=medium
 .
   [ Samuel Thibault ]
   * hurd-i386/cvs-gprof-tick.diff: Cherry-pick from upstream to fix gprof
     timing.
   * hurd-i386/cvs-IPV6_PKTINFO.diff: Cherry-pick from upstream to fix
     IPV6_*PKT* macros.
 .
   [ Aurelien Jarno ]
   * Update from upstream stable branch:
     - Fix a buffer overflow in the glob function (CVE-2016-1234).
     - Fix a stack overflow in getaddrinfo function (CVE-2016-3706).
     - Fix nss_hesiod breakage.  Closes: #821358.
   * patches/kfreebsd/local-sysdeps.diff: update to revision 6051 (from
     glibc-bsd) to fix FTBFS and provide PT_FOLLOW_FORK in sys/ptrace.h.
     Closes: #822143, #823387.
   * patches/arm/unsubmitted-ldconfig-cache-abi.diff: apply fix from Steve
     McIntyre to fix an armhf ABI detection crash in ldconfig on arm64.
     Closes: #822489.
   * debian/control.in/main: upgrade breaks on binutils. This is plainly
     wrong though, glibc should not be a special case: either we don't
     support partial upgrades or we do that for all libraries. With that
     let's hope people will stop reporting bugs, sigh.  Closes: #819165.
   * Drop libc*-i686 packages as GCC now defaults to i686:
     - debian/control: drop packages, add provides and build-depends on
       g++-5 (>= 5.3.1-17) and dpkg-dev (>= 1.18.7).
     - debian/sysdeps/hurd-i386.mk: stop building libc0.3-i686. Use the
       default compiler options to build libc0.3-xen.
     - debian/sysdeps/i386.mk: stop building libc6-i686.
     - debian/sysdeps/kfreebsd-i386.mk: drop.
     - debian/patches/i386/submitted-i686-timing.diff: drop.  Closes:
       #218519.
 .
   [ Adam Conrad ]
   * debian/control.in/libc: Force i686 variants off the system on upgrade.
