FuguMod is a secure, open, reliable and no nonsense kernel

This is probably the only custom kernel for the Nexus 5 which adds security instead of removing it.

Current features are:
- compiled with linaro gcc4.7.4
- various small fixes

You can download the kernels at:
http://fugumod.org/nexus5

Source and changelog can be found here:

irc.freenode.net #fugumod

Flashing
Kernel zips are intended to be flashed with CWM ot TWRP, if you want to flash using fastboot, you need to unpack the zip and flash the boot.img which is inside

Versions
Kernels are based on the below version scheme
kernel_FuguMod_20131104_r1-4.4.img
20131104 is the date it has been packaged
r1 is the release number
4.4 is the ROM it is compatible with

Stable vs Testing
There are sometimes kernels in testing folder. These may be very stable or may not boot at all. Be sure to have an USB cable and fastboot under the hand if you try one of these. That said, in general, if they stay into testing folder for more than 15 min, they should at least boot and work more or less. I tend to remove non booting kernels from testing folder in less than 10 min (depending a little bit on the speed testers take them), and so if you see them one hour later, you should assume they are safe enough to flash.
So, in general Stable is the safest bet, but Testing may be the best. I, myself, generally run testing one.

Deprecated folder
In general, unless you really know what you are doing, you should avoid flashing those, they are mainly there for historical reasons.

Compatibility with hackish style apps
All apps which require direct memory write, access to symbols or memory offsets or modules will NOT work. And, no, don't ask they won't be supported in the future. Example: Arararagi's light is only provided as a module and will not be supported unless he produces a patch.

Security
If you want good security when your phone is stolen, in addition to encryption, don't forget to turn debugging off. Also, use enpasschanger to change your encryption password, any short PIN encryption can be cracked in a few minutes easily (for example, using my script at http://pastebin.com/Mdu06RZN)

Redistribution
As per GPL, you are authorized to redistribute this kernel with any of your custom ROMs provided you give out the source code like I do. You can link to my github in your distribution site.
However, if you modify the kernel yourself, whatever the modification is (compiling it yourself with a different compiler is a modification), you are not authorized to name it FuguMod, although you can credit me and tell the base comes from FuguMod but you cannot call the kernel itself FuguMod.

Hello @renaud.

It's really nice to find a lot of people coming from Galaxy Nexus to the Nexus 5. As the Galaxy Nexus is an oldie (yes, two years), there are less and less threads supported. I hope, you will still support the Galaxy Nexus - but also the Nexus 5, of course. Good to have you in here! :laugh:

after booting, i flashed it via bootloader.

I suppose you meant you flashed with fastboot.
Whatever, till how far does it go?
I am wondering, did you unpack the zip and flashed boot.img through fastboot, or did you flash the whole zip through fastboot??

tried out your kernel, alot of nice features but stock seemed to run faster. cant wait to see what the community has to offer over the next couple of months. pushing the phone to its limits / extending battery life.

Thank you for confirming that it boots. Currently it has no features except being smaller than the stock one. I was waiting for the boot confirmation before developing.

    I have now received my N5. Real stuff will begin.

    hope to see something from you soon, AK!

    Im waiting to sell my n4 .... but for now im observing ....

    So I will take back development of this kernel again. It seems most of the features of grsec (which was available in testing version) makes this kernel really unstable.
    I will soon make a CM compatible version.

    I have promoted r35 as stable given that I did not succeed getting a crash since it's out.
