Hi all,

I have a newbie question. I’m using a 3.18.66 kernel branch from Qualcomm. Over the year I’ve applied some of patched here and there manually.

But It seems Qualcomm does not patch lot of newly released vulnerabilities. I would love to upgrade to the latest 3.18.138 (not 4.x)

What is the best practice here? 

Thanks
-Dan

Since you're being forced by Qualcomm to use 3.18, take it up with them.

What's this? You say you're not forced to do it?  Well, there's two things you
can do:

1) Continue feeling the pain of running an old kernel
2) Fix the reason you're on 3.18, and get on a 4.x or 5.x kernel.

Your choice.

Merge your branch with the android-common 3.18 branch, and try to run
that.  Note, there will be some conflicts, and I think there's a random
qualcomm branch somewhere on code aurora somewhere that has those
problems resolved if you have problems with them.

good luck, it's possible to do (I have a phone running the latest 3.18
release on it with a qcom chipset), but it all depends on exactly what
device you have as to how easy/hard it is going to be!
