# Make HipChat grsec friendly
#
# To build the Docker image, I currently had to disable the following grsec protections:
# # grep -E "chroot_deny_chmod|chroot_deny_mknod|chroot_caps" /etc/sysctl.d/grsec.conf
# kernel.grsecurity.chroot_deny_chmod = 0
# kernel.grsecurity.chroot_deny_mknod = 0
# kernel.grsecurity.chroot_caps = 0 (relates to a systemd package)
#
# (runtime only, since xattrs are not preserved in Docker's final image)
# m: Disable MPROTECT // grsec: denied RWX mmap of <anonymous mapping>
# RUN setfattr -n user.pax.flags -v "m" /opt/HipChat4/lib/HipChat.bin /opt/HipChat4/lib/QtWebEngineProcess.bin
#
# (permanent change, by converting the binary headers PT_GNU_STACK into PT_PAX_FLAGS)
# m: Disable MPROTECT // grsec: denied RWX mmap of <anonymous mapping>
