I don't know about opptimizer though as I don't overclock my N9....

Thank you for this. This fix worked.

BTW, extra thanks for a nice way of showing "instructions". Simple, clever and working.

Yeah but even with cd /home/user/MyDocs# same result!

First installed 'standard' opp 1.5.4 and ui 1.2.7 due to this
http://talk.maemo.org/showpost.php?p...&postcount=632

and it worked but setup Opp and run Optimize test said error 'No such file etc'

Then your attachment opp-kernel-plus 1.5.3 with mentioned result:confused::confused:

EDIT: reboot tried again and now install seems to work!:)

But same message as with standard 1.5.4 'No such file or directory' trying to setup and run Opptimize test button! What's wrong here:confused:

I know I know, it would only be helpful if juiceme (ubiboot) and e-yes (nitdroid) would fix their kernels also. And even than nemo/sailfish/other would need to reside on partitions lower p8, but that would offer a lot more of possible partitions/OSes/playground.

Huh, never encountered this bug. Maybe because I'm on a 16GB N9 :P

Looks like enabling GPT in the kernel was only half the battle! Will patch and rebuild as soon as possible, if it doesn't break anything (it shouldn't, iirc /sbin/preinit is nice enough to mknod things for you)

Going forward, merging all the space on the device with flexible subvolumes and saving space with deduplication would be nice ;)

I've made some strides towards fixing kexec() stuff so kernel-plus, built with a different configuration, could be used as ubiboot's kernel. Too lazy to rebase back on the git kernel tree yet.

This will hopefully land with the next source drop.

Also, congrats on the Council, juice!

kernel-plus includes the Opptimizer modules, version 1.5.3 to be exact. You should use coderus' opptimizer-ui, it skips over some checks.

The official Opptimizer 1.5.4 modules are rejected by the kernel - they're built against ol' 2.6.32.54 ;)

I still have some space left on my extended part so I could be the guinea pig if you like/finish (whenever).

Remove everything related to Opptimizer you have installed. Reinstall kernel-plus.

Now, install kernel-plus, and on top of that, install coderus' Opptimizer UI. Modprobe opptimizer. Launch the UI, and it should work.

Re: [Announce] kernel-plus for Harmattan

OK Opptimizer now works with kernel plus using coderus core 1.5.3 together with UI 1.2.7.
But using Ubiboot and switch between kernels shows that Opptimizer then don't work with kernel l2fix (shows Unknown setup and test button 'No such file or directory) so you have to choose which kernel to use if using Opptimizer!?:rolleyes:

After booting kernel-plus a reboot occurs after playing the nokia sound (if there was no ubiboot, it'd be a reboot loop)

Why can it happen?

Could be many reasons.

If your installation has been correctly done (all modules in correct folder, depmod done, no funny business in preinit...) then the problem might be one of your specific device.

What you might want to do is use flasher to disable the watchdogs in R&D mode and try if you can boot it up that way. (sudo flasher --set-rd-flags=no-omap-wd,no-ext-wd,no-lifeguard-reset)
Then check your syslog to see what's the thing that ails you.

If that does not work, then hooking up serial console is the way to find out (almost) all boot related problems.

Re: [Announce] kernel-plus for Harmattan

Can someone tell me how far this open mode goes? uname -a returns the correct kernel version, and the system works a lot faster than the normal n9 one, which is really nice to see.

But Ive tried to install a package with dpkg -i and Ive received an aegis security error. So I guess aegis is not fully patched out?

using dpkg.real did the trick, but normally the kernel should disable aegis, or do I understand it wrong?

coderus

2014-01-26 21:49

Re: [Announce] kernel-plus for Harmattan

openmode patch includes allowing to load unsigned kernel modules, executing binaries from any location, unrestricting root privileges and disabling refhash integrity check. thats all.

you cant remove aegis from kernel, because many os components are based on aegis services, and you cant rebuild system.

if you want aegis-free environment you'll use Nemo.

It's the same Open Mode other kernels use.
The patched dpkg checks for file signatures when installing system packages - are you using you used

Re: [Announce] kernel-plus for Harmattan

Just a little update, since I've been off TMO for quite a while:

I'm working on rebasing kernel-plus on top of the Mer N9/50 2.6.32 kernel and Mer toolchain, as the Harmattan SDK is officially offline (and deprecated, if I kept building with HSDK, it'd be a pain for others to install and build using it), and it'd be a lot easier to track Git commits with the log from the Mer N9 kernel.

Re: [Announce] kernel-plus for Harmattan

@Hurrian @Juiceme i have a non-standart question. Is there any way in kernel to have display framebuffer in portrait rotation? I'm asking because of sailfishos v > 1.0.2.5 going to be crazy on N9's framebuffer. I know about fbrotation cmdline parameters, but it seems not to work.

Well, rotation works, sorta. The problem is, there's some kind of bug that b0rks up rotation at 90 and 270 degrees (echo {1,3} > /sys...)

I suspect it's related to this bug report filed quite some time ago.

WARNING: This will flip display 180 degrees, but touch mappings will not rotate! You may need to reboot after.

Code:

echo 2 > /sys/class/graphics/fb0/rotate

I've trashed my build VM with the Harmattan SDK on it, leaving me with one option - migrating to Mer+SB2 SDK.

~~One problem though - while setting up the Nemo rootfs for cross-building, releases.nemomobile.org turned out to be down, which means I can't move forward with setting up for builds.~~

The source code is here for anyone with a functioning Mer+SB2+Nemo N950 SDK.

Beyond that, I wager something broke in the squashed Linux updates.

Right now, I've got it booting to the Nokia logo (/sbin/preinit_harmattan), which means I'm able to run Harmattan binaries.

I've spent the night patching Aegis to build and link properly against 3.5.3, ~~but it doesn't register as a LSM~~
This turns the boot process into potato once /sbin/init runs, as IIRC it has Aegis hooks.
Maybe I need to disable the stock Unix DAC?

I'll make a diff and post binaries for any devs to test and work with me in a few.

Based on filippz's kernel source tree.

EDIT:
I've gotten aegis to load as a LSM! :D

One minor problem - it looks like due to some methods I've removed (due to deprecated kernel API or somesuch) cause aegis to go completely tits up.
You will get a MALF if you boot this kernel, in its current state.
You will render Harmattan unbootable (broken refhashlist?)

On the plus side, validator-init runs (you get the MALF screen), which means userspace is communicating with the kernel (not in the way we'd want to, but hey, it's a start!)

Points of interest:
security/aegis/validator/validator.c
@525: ipp_hashlist_load [...]
Function entirely removed and stubbed, first oops.
The original code (this commit, same file, line 530) can probably be rewritten.
The code in question that breaks:

Code:

bufptr = dentry_path(file->f_vfsmnt->mnt_mountpoint, buffer, buflen);

[...]

if (file->f_vfsmnt->mnt_parent != NULL) {

Changes that broke the original function: 1, 2

@1338: #if CONFIG_SECURITY_AEGIS_CREDP
.task_setgroups and .task_setgid are removed, reflecting a kernel API change (1, 2)
Investigate how important these LSM hooks are to Aegis?

security/aegis/validator/enforce.c
@188: valinfo.hashreq [...]
Should probably be changed back to

Code:

valinfo.hashreq = (val & HASH_REQ_BIT) ? 1 : 0;

once validator.c:525 is fixed.

WARNING! READ THE ABOVE FIRST!
The kernel is here
compiled with debug info and more printks, in case some of you have a serial port adapter and/or a propensity for kdb
Source patch is here
apply on top of filippz's kernel source tree
use n9_harmattan_defconfig to build a kernel with aegis enabled
