This is a note to let you know that I have just added a patch titled coredump: fix the setting of PF_DUMPCORE to the linux-3.11.y-queue branch of the 3.11.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.11.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.11.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From 928aeee05e2d0566179b6ba7fb1d783a9fa18fc2 Mon Sep 17 00:00:00 2001 From: Silesh C V <svellattu@mvista.com> Date: Wed, 23 Jul 2014 13:59:59 -0700 Subject: coredump: fix the setting of PF_DUMPCORE commit aed8adb7688d5744cb484226820163af31d2499a upstream. Commit 079148b919d0 ("coredump: factor out the setting of PF_DUMPCORE") cleaned up the setting of PF_DUMPCORE by removing it from all the linux_binfmt->core_dump() and moving it to zap_threads().But this ended up clearing all the previously set flags. This causes issues during core generation when tsk->flags is checked again (eg. for PF_USED_MATH to dump floating point registers). Fix this.
