Package: libc6
Version: 2.21-0experimental0
Severity: normal
Tags: upstream fixed-upstream
Forwarded: https://sourceware.org/bugzilla/show_bug.cgi?id=18463

Hello,

the attached program fails with an error on ARM platforms. (I only tested
armhf, but I think armel is affected, too.)

The problem is that pthread_mutex_unlock() in the main thread returns
EPERM which it shouldn't. This only happens when using
pthread_cond_broadcast, at least two threads and PTHREAD_PRIO_INHERIT.

For more details refer to the upstream bug[1].

A possible solution documented in the upstream bug report is to pass
--enable-kernel=3.15 (or something bigger). 
According to
https://buildd.debian.org/status/fetch.php?pkg=glibc&arch=armhf&ver=2.21-0experimental0&stamp=1426842906
glibc is build using --enable-kernel=2.6.32, I guess that's from the
setting MIN_KERNEL_SUPPORTED in debian/sysdeps/linux.mk.

Given that stable has kernel 3.16 the probably easiest solution would be
to bump the dependency to >= 3.16?!

Best regards
Uwe

Changes:
 glibc (2.21-0experimental2) experimental; urgency=medium
 .
   [ Samuel Thibault ]
   * Symbol versions which contain _DEBIAN_ are unexpected by upstream scripts.
     Add hurd-i386-only patches/hurd-i386/local-versions-hack.diff to work
     around the issue.  Also take the opportunity of the upstream version bump
     to bump the versions to GLIBC_2_21, which will allow one to remove the
     _DEBIAN_ hacks once packages are rebuilt.
   * patches/hurd-i386/unsubmitted-libpthread-semaphore.h.diff: Remove
     libpthread/sysdeps/i386/bits/semaphore.h, now that hurd Implies
     libpthread/sysdeps/generic. Move libpthread/include/semaphore.h into
     libpthread/sysdeps/pthread/semaphore.h instead of the latter just
     including the former, since the latter is what gets installed.
   * patches/hurd-i386/cvs-cache-mach_host_self.diff: New patch to avoid port
     count issue on the host port.
   * patches/hurd-i386/unsubmitted-gnumach.defs.diff: Also build
     task_notify.defs stubs.  Drop unneeded change.
   * libc0.3.symbols.hurd-i386: Update.
   * patches/hurd-i386/local-mach_print.diff: New patch to export mach_print.
 .
   [ Aurelien Jarno ]
   * rules.d/debhelper.mk: replace GLIBC_VERSION before LIBC.  Closes:
     #797538.
   * Drop loongson-2f flavour on mipsel as this machine is not supported
     anymore (default to R2 ISA).
   * kfreebsd/local-sysdeps.diff: update to revision 5772 (from glibc-bsd).
     Closes: #764692, #785796.
   * testsuite-checking/expected-results-mips*: allow the new tst-audit9
     fail, like the others tst-auditX.
   * testsuite-checking/expected-results-mips(el)-linux-gnu-libc: allow
     conformtest for sys/stat.h to fail for O32 ABI. They were previously
     under the failing test run-conformtest.out, but it has been lost in
     the conversion to the new format.
   * testsuite-checking/expected-results-mips*: sort the files. Remove
     failures due to old kernel now that all buildds run jessie.
   * debhelper.in/locales-all.prerm: do not specify a path to check for
     locale-gen.
   * libc6.1.symbols.alpha: remove invoke_dynamic_linker from libpcprofile.so.
     It has disappeared, but it is a private library.
   * Remove debver2localesdep.pl, it is unused since 2.19-16.
   * Use $(GLIBC_VERSION) for shlib, instead of defining the version in a
     separate shlibver file.
   * Remove completely outdated README, README.source and TODO files.
   * rules.d/debhelper.mk: use the default compression format for libc6,
     libc-bin and multiarch-support. Nowadays deboostrap is able to handle
     the xz format and modern distributions also support it. Anyway almost
     all packages installed by debootstrap are now using the xz format.
   * Bump debhelper compatibility to level 9. This brings compressed debug
     file using the build-id instead of a fixed path. This is much more
     multiarch friendly.
   * control.in/*: remove pre-squeeze conflicts.
   * libc-bin, libc-dev-bin: Recommends the manpages package and add lintian
     override for missing manpages.
   * sysdeps/s390x.mk: --enable-lock-elision.
   * testsuite-checking/expected-results-x86_64-linux-gnux32-*: allow
     conformtest for headers with tv_nsec to fail for x32. The type
     non-compliance is intentional. These tests were previously marked as
     failing under the run-conformtest.out, but they have been lost during
     the conversion to the new format.
   * testsuite-checking/compare.sh: re-enable failures in case of regressions.
   * rules.d/build.mk: don't require flavours to be tested before being
     installed. They are still tested when calling the build-arch or
     binary-arch targets, but not anymore when calling the build-indep or
     binary-indep targets.
   * patches/hppa/cvs-alloca-werror.diff: new patch from upstream to fix a
     build failure.
   * debhelper.in/libc.preinst: fix up error message for too old Linux
     kernels.  Closes: #800846.
   * patches/any/cvs-ld_pointer_guard.diff: new patch from upstream to
     unconditionally disable LD_POINTER_GUARD.  Closes: #798316, #801691.
   * patches/any/cvs-mangle-tls_dtor_list.diff: new patch from upstream to
     mangle function pointers in tls_dtor_list.  Closes: #802256.
   * Update Brazilian Portuguese debconf translation, by Adriano Rafael
     Gomes.  Closes: #799418.
 .
   [ Steven Chamberlain ]
   * sysdeps/kfreebsd.mk: find kfreebsd-kernel-headers in multiarch path.
     Closes: #672774, #798064.
 .
   [ Helmut Grohne ]
   * Fix some issues with stage 1.  Closes: #797831.
 .
   [ Adam Conrad ]
   * debian/patches/arm/local-arm-futex.diff: Lie about the minimum kernel
     support for futex_atomic_cmpxchg_inatomic to restore the  previous state
     and fix the pulsesink (and others) regression on ARM (closes: #788799)
 .
   [ Henrique de Moraes Holschuh ]
   * Replace patches/amd64/local-blacklist-on-TSX-Haswell.diff by
     local-blacklist-for-Intel-TSX.diff also blacklisting some Broadwell
     models.  Closes: #800574.
