This is a note to let you know that I have just added a patch titled s390/bpf,jit: initialize A register if 1st insn is BPF_S_LDX_B_MSH 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 390e690c940755b1bed255b41983dd662a3f911f Mon Sep 17 00:00:00 2001 From: Martin Schwidefsky <schwidefsky@de.ibm.com> Date: Fri, 25 Apr 2014 10:53:44 +0200 Subject: s390/bpf,jit: initialize A register if 1st insn is BPF_S_LDX_B_MSH commit 6e0de817594c61f3b392a9245deeb09609ec707d upstream. The A register needs to be initialized to zero in the prolog if the first instruction of the BPF program is BPF_S_LDX_B_MSH to prevent leaking the content of %r5 to user space.
