[yocto] kernel patches

[Sona Sarmadi]

Hi all,

I wonder how you handle the kernel patches? 

I want to apply a security kernel patch to Linux-yocto 3.10  which is used by Romely:

meta-inte/meta-romley/conf/machine/romley-ivb.conf:PREFERRED_VERSION_linux-yocto ?= "3.10%"

For me the obvious way to fix this is:
1) Create >> "poky/meta/recipes-kernel/linux/files" directory and add the patch file there

2) modify: poky/meta/recipes-kernel/linux/linux-yocto_3.10.bb


-SRC_URI = "git://git.yoctoproject.org/linux-yocto-3.10.git;bareclone=1;branch=${KBRANCH},${KMETA};name=machine,meta"
+FILESEXTRAPATHS_prepend := "${THISDIR}/files:"

+SRC_URI = "git://git.yoctoproject.org/linux-yocto-3.10.git;bareclone=1;branch=${KBRANCH},${KMETA};name=machine,meta \
+          file://Fix_for_CVE-2014-0196_pty_layer_race_condition.patch \
+          "

Please let me know if this is the correct way. And also let me know if I upstream this kernel patch to yocto, will yocto accept it (if the patch looks correct of course). Please let me know if you prefer to apply security patches to kernels in some different way.

Thanks
