Container kernel parameter net.ipv4.tcp_syncookies for oracle 11g xe fail

Hi,
I am running OracleLinux7 with docker 1.6.1
I ran a container privileged (due to kernel.* settings required by oracle) like so:

docker run --privileged=true -i -t --name sascha oraclelinux:6.7 /bin/bash

then when trying to install oracle 11g xe I am getting this error:

error: permission denied on key ‘net.ipv4.tcp_syncookies’
error: %pre(oracle-xe-11.2.0-1.0.x86_64) scriptlet failed, exit status 255
error: install: %pre scriptlet failed (2), skipping oracle-xe-11.2.0-1.0

but the setting is already set to 1, as it should
so the privileged fixed all kernel.* and net.ipv4.* required for oracle, except this one

oracle 11g xe installs fine in lxc as it passes on the host kernel settings

Try to change this kernel parameters yourself manually and them rerun the rpm install:-

vi /etc/sysctl.conf
and add the following lines:-

fs.file-max = 6815744
net.ipv4.tcp_syncookies = 1

Then run

sysctl -p
