Title: linux-lts-trusty: 3.13.0-57 introduced bad ELF layout for PIE Status in linux package in Ubuntu: Invalid Status in linux source package in Trusty: Invalid Status in linux source package in Utopic: Invalid Status in linux source package in Vivid: Invalid Bug description: Since 3.13.0-57 there is the following patch applied: "fs/binfmt_elf.c: fix bug in loading of PIE binaries" (https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=a87938b2e246b81b4fb713edb371a9fa3c5c3c86) But it is incomplete as its fix is missing: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=2b1d3ae940acd11be44c6eced5873d47c2e00ffa And it completely messes up the PIE regions as it loads unrelated stuff between .text and .rodata of the PIE binary. See: https://github.com/scanmem/scanmem/issues/122 Upstream fixed that by the following commit: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=d1fd836dcf00d2028c700c7e44d2c23404062c90 So there are two options here: 1. remove that patch 2. apply the other fixes as well Also 3.16.0-41 is affected.
