[apparmor] AppArmor Kernel-patch 3.6 in kernel 3.14 // for (p = profile->replacedby; p; )

[Jae Suk Park]

My environments are listed here.
Target Linux kernel is 3.14.28 customized by freescale running on ARM core
user space AppArmor source is  2.8.95_rev2434


Whole procedures are listed here.
1. Target board is Freescale based on ARM core
2. Target Linux kernel is 3.14.28 which is customized by Freescale (not
upstream version, but dev version by Freescale like ubuntu release)
3. Build Server is ubuntu 14.04 LTS (Kernel 3.13.0-68) with Yocto build
tool-chain (poky)
4. download apparmor 2.8.95 rev2434, with this command "bzr co
lp:apparmor --rev
2434" on build server.

revno: 2434
tags: apparmor_2.8.95

---------------------------------------------------------------
    I chose rev2434 because I thought it was made for kernel 3.14 (
https://launchpad.net/apparmor)
   ## apparmor source package in Trusty  (14.04 LTS, Kernel 3.13~3.19)
   ## Version 2.8.95~2430-0ubuntu5.3 uploaded on 2015-06-18

5. build on ubuntu system to check build is working.
followed README file like there. (previous email "Yocto apparmor porting"
has details)
   userspace : libapparmor/ ./configure --prefix=/usr --with-perl
--with-python , make, sudo make install
                      utils/, parser/, profiles/   make, sudo make install
   python2.7 environment : ImportError: No module apparmor.tools, lightdm,
LibAppArmor error.

6. Yocto building, write bitbake recipe file [  do_configure(),
do_compile(), do_install()  ]

7. Yocto kernel, cross-compile after adapting patches in
"/kernel-patches/3.3 ~ 3.12" directory.
   I couldn't find 3.14 patches in "kernel-patches"directory. so I thought
patches is cumulative,
   but Mr. SethArnold mentioned those patches should apply to separate
kernel version.
   then referring to trusty/utopic
           http://kernel.ubuntu.com/git/ubuntu/ubuntu-trusty.git/tree/
           http://kernel.ubuntu.com/git/ubuntu/ubuntu-utopic.git/

   and Mr. JohnJohansen mentioned upstream or dev kernel of my environment.
and (I guess) I need dev version of apparmor patches for Yocto-3.14.28
customized by Freescale.

Thanks for your comments on this.
