Hi kernel hackers,
it is getting very silent recently about possible security hacks on the Milestone platform.
Today i stumbled over some kernel code located in /drivers/misc/sec.
Maybe this had been discussed already.... anyway
There're some interesting functions in the source code and i wonder which application is using this module to enter the secure world of OMAP.
Some of the functions are accessing registers, that are also involved in low level routines of the bootcode (e.g. mbmloader).
Some questions:
Which application in android userspace is using this module?
Could we tweak this module to get access to some of the protected OMAP registers?
Is it a signed module?
Would be nice to use a modified module and activate some of the blocked features (e.g. DAP controller for debugging).
Any comments welcome!!!

Well, I'm not a kernel hacker, but I have an educated guess...
I believe that the radio system uses those functions to check whether the kernel is valid or not, so, we have the radio not working with a replacement kernel that is loaded using kexec...
Perhaps, if it is possible to "change" this function using a module, we could get a function always telling the kernel is valid and have kexec working on Milestone. Again, I'm not a kernel hacker, but that is my guess.

Hi,
thanks for your comments so far.
To be more precisely i think this kernel driver is calling the secure monitor in some way. See here:
https://www.droid-developers.org/wiki/Secure_Monitor
There's also a structure defined in that driver. I think i'll have to compare some of the ioctl entries.
https://www.droid-developers.org/wiki/Secure_Services
I'll do some investigation on this issue and search the web for some userland source code using this driver.
Again, if someone knows more about it, your welcome
Cheers,

Yeah sure, i knew this
Anyway, thanks for the hyperlink!
In the meantime i grepped all binaries from the latest distribution.
I found out, that two applications are using /dev/sec.
1. dbvc_atvc_property_set
2. tcmd
If someone knows which package of source code they belong to... would save some time searching.
EDIT:
O.K. Google did it for me...
Seems that both binaries are proprietary code. Some early conclusions:
1. dbvc_atvc_property_set
This one is started as a service in init.mapphone_umts.rc and seems to use /dev/sec for granting rights to access OMAP secure world (e.g. read eFuse values for unique device id, IMEI etc.).
This binary contains a certificate which is not Milestone specific (XT720 uses the same).
So right now i don't know, if this certificate is needed to access /dev/sec or the application itself identifies itself as trusted application (signed app).
Would make sense, if the BP uses signed applications to access certain low level functions, e.g. read/write the eFuse bank.
2. tcmd
This one is also started as a service in init.mapphone_umts.rc to access a variety of devices. Seems to be related to data streaming or stuff.
As stated it has an entry for /dev/sec and it got no certifcate.
Would be interesting to get some more info about that.
Further comments....
P.S.: This bloody security stuff is making me sick

Hi again,
i just compared some of the defines in the kernel driver headers (/drivers/misc/sec/sec_core.h) with the ones xvilka reversed inside mbmloader.
Code:
...
#define API_HAL_KM_SOFTWAREREVISION_READ 33 // 0x21
...
#define API_HAL_NB_MAX_SVC 39 // 0x27
#define API_HAL_MOT_EFUSE (API_HAL_NB_MAX_SVC + 10) // 0x31
#define API_HAL_MOT_EFUSE_READ (API_HAL_NB_MAX_SVC + 15) // 0x36
...
For comparison see the table here:
https://www.droid-developers.org/wiki/Secure_Services
It is obvious that /dev/sec allows to access OMAP secure world and uses the above mentioned API calls to push information to userspace apps.
The question would be, if ioctl must be certified through the API using some key ...
O.K. i see this is deep down code creeping, but maybe someone understands what i try to work out
See ya,

I think I know what you are trying to work out, but I can't think of any way to help
You're pretty much comparing the results of your findings with that of the mbmloader dump right?
I would like so much to fully understand what you are doing, but I can understand just a little..
btw I hope that you'll be glad to know that you have all my psychological support!

Yeah, kind of... we know for sure there's an API to access security functions on OMAP. I just digged out some parallels in kernel code and mbmloader.
If we could make use of security functions from within kernel space (by using a tweaked module) this would be a nice playground.
Perhaps, there's any bug or backdoor we could shamelessly exploit to:
a. boot custom kernel with second boot
b. tweak the security system and enable some hidden functions inside OMAP

I got into contact with xvilka.
Obviously there'd been some investigations concerning this issue.
To be honest, i don't know if it's worth to digg a little deeper or if it will ever led to something useful in the end. Could be fun though
Perhaps it would be nice idea to tweak the driver and put some debug message in the code.
Another interesting thing to do would be a logging function.
This way it would be possible to get some insights of the API to secure monitor.
Anyway, i think it's never useless to discuss about some hacking here. At least were at xda-developers
If you like to tweak some kernel code, join in!!!
Have fun!

Hello,
Just bough myself the amazing Galaxy Note 10, and it has "Peel Smart Remote" built-in app.
This app works fine with a lot of TV brands, but I believe it could be even better.
Are there any other apps that can control that IR emitter as well?
I want to be able to control my cable TV decoder, as well as other devices in my house, that are NOT available on peel.
As I'm trying to learn android dev (very beginning yet), I would love to know how to write my own app, so I could try to write something useful.
However, there are NO DOCS AT ALL about it! Not on Android SDK, not on Samsung SDK. No API related, absolutely nothing.
Looking at Samsung developer forums, their oficial position about the subject is that "there is no information about it, that's all we known".
Well, if "Peel Smart Remote" app is able to control that infrared chip, it MUST have a way for us (developers) to do the same!
Can anyone tell me/us how to start?
I don't know, maybe a little reverse engineering in peel's source code to find out how peel works, and reproduce it!
I believe I'm not the only one that is looking for some different uses for the IR Led Emitter on the Galaxy Note 10, so let's try to figure out something!
Thanks!

Hummmm now that was weird...
I just downloaded that touchsquid demo, and they have A LOT of limitation on the demo version: "you cannot try the samsung TV in this demo version". Also, you can't download it from market/play, you download the INSTALLER from play, and have to allow "allow other source" to install it.
I mean, if peel is obscure, touchsquid is even more!
What are they afraid of?
nope!
Demo mode has limited function because of license...send me a pm arr arr!
You install the .apk from market, And then You install the help And settings apk. These two are separat. No Idea why.
The developers of touchsquid are extremely responsive, I paid the £11 for the Samsung tablet version, it nicely controls my UK sky+, Samsung tv and hdmi switcher "straight out of the box" and after a couple of email exchanges my Phillips DVD system, they responded to emails the same day and in both cases updated their device database with correct ir codes within 1 to 2 days. Bearing in mind how poor Peel its for non American users, this it's the only alternative at present, it's a bit of a niche due to the general lack of devices with an ir emitter so any attempts of the developer community to make one would be keenly anticipated

I wish Logitech would get in on this. I LOVE my harmony one remote, and would happily pay for an app that would let me do the same with my tab, even if it is a spendy app.

That's strange - stupid Logitech! I found that the best IR software for Android is the one that comes with the Sony Tablets. It has a great database of existing devices, but it also allows the IR blaster to learn commands from existing controls (ie I have an infra-red controlled light switch which it works with).
I imagine if there is an API for the IR Blaster someone could program such features in.....it's frustrating that Peel doesn't work with Sky though. I might try the suggestion above myself.

Just sent. License from who? Samsung? I mean.. Do we need to have a licensed remote control to work with Samsung (or other) devices?
Or is the license about using their trademark?
I mean, (if we got that API), can't we develop apps to control Samsung (and other) devices?
Can't we share them for free on Google Play? I can't think a way that this would cause financial losses for them!

Actually, Galaxy Tab/Note only have IR Emitter.
It doesn't have a receiver, that's why we can't have a "IR Code Learning" with our Galaxy Tab and Galaxy Note.
Are there any developers here who can help me disassembly existing APKs, and try to find out how to control that IR chip?
I never worked with Java before, only learned to disassembly compiled C/C++ applications...

As said before it's merely a blaster - not a receiver. Touchsquid is great but sadly the ui is seriously lacking polish!!
Yeah, yeah, I get that the Note 10.1 does not have a IR receiver. If you read the quote I list, a poster claims to have a switch that allows the sony app to learn. Hence, I asked for a link to the app and the switch.

No he doesn't - because that was me who said that. In fact, what I said was there is on the Sony S Tablet, the program is capable of learning commands BECAUSE the Sony has an IR receiver built in. Which doesn't help us because the Note 10.1 doesn't (which I have found out since making that post). I never said it would work on the 10.1!

Well the Note hasnt a dedicated IR receiver, but maybe the camera could just do the same job. You can see the IR diode of any remote flashing if you point at the camera whilst using the cam app. Anyway there are already tons of IR codes available on the web, all we need is an app which is way more customable than the Peel app.

What is really a "IR Code"?
Is that about the frequency of IR Led Blinking?
For example, on PEEL you have to choose your device, than you can customize key codes.
Example: My LG TV: Vol-up=326, Vol-down=327.
Peel doesn't support it, but let's say it DOES, and I choose "Samsung TV", but customize the Vol-Down code to "326".
Will it work on my LG TV? Or are there any other variables that intereferes on it?
I mean, if the only variable is that "code", than we could make a "Brute force" trying codes from 1 to 6556, and pause it when something happens to our TV or any other device, is that right?
About the camera working as a IR Receptor, that really would makes sense IF camera could take enough fps to decode the frequency.
That's something to investigate.
Are the programmers in "Android Development" aware of this thread? Someone with a little more technical information could add more to this thread (I can't post there, unfortunally).
Here's a good explaination of codes: ww w. hifi-remote.c om/infrared/IR-PWM.shtm l.
Some raw LG codes are here: files.remotecentral.c om/library/3-1/lg/2008_television/index.ht ml.
For the moment i have no idea how the 'code' number in the Peel remote is linked to the raw code. Illhave a look there tomorrow
Does anyboda have new informations regarding a infrared remote APP?
It would be great if I could remote control my LED Stripes with the Galaxy Note 10.1. There are some similar apps like IRDroid but all are using an external device.
Would it be possible to use the integrated infrared interface in android APP?
I copied the following response from Samsung's developer forum. Samsung will not release the API for the IR blaster on Galaxy Tab 2 series.

Here is another forum post, I noticed that the username of the last response is "TouchSquid". They must have either talked to someone higher up at Samsung or figured it out on their own since they now offer an app.
developer.samsung.com/forum/board/thread/view.do?boardName=GeneralB&messageId=140654
This lack of an SDK is both bizarre and confusing. Both of the available apps - Peel and Touchsquid - are useless for different reasons. If you could combine them both then they might add up to a useful app but separately they're useless. I've tried and uninstalled both.
The thing that's really needed is someting I've been after for a long time and I'm surprised no-one has yet thought of it - a combined IP Remote. All the Hifi and electronics manaufacturers have their own apps and SDKs to control their equipment over wifi and each one needs to be installed separately. Imagine a single interface that could talk to all of the various IP controls. You wouldn't need an IR port then, just a set of IP controllable equipment.
It could be extended to incorporate things like Mediaportal or XBMC, WDTV live, AppleTV? - basically anything with a web based interface and an SDK. Build it so that each remote is added as a plugin and it can be expanded as each new device comes along. It would be the ultimate Home Cinema remote!
Someone get on it!
I developed a new Infrared Remote Control that is a little like the one from Sony. Using StandOut, I have achieved that the Remote is usable like the Mini App from the Original Tablet Z Firmware (See Screenshots). As Backend the IR Library from Apache14 is used. For now the App is only compatible with >= 10.1" Tablets with a resolution of >= 1920x1080. I successfully test and run this on my pollux running nightly builds of CM 10.1 but it should work on any AOSP compatible ROM with superuser access. All in all, if Apache14's reference implementation from here worked on your device, this build should do so as well.
I also released the first draft of the Source Code on github.
https://github.com/lowtraxx/TSRemote
It is a preview version, so it is still a little rough around the edges. But you can Program Remote Controls, add new ones and use it like the regular one on the Original Firmware.
Prerequisites:
- Only tested on CyanogenMod 10.1 nightly but any AOSP compatible ROM should work
- Superuser Access (The App changes permissions for the IR device files)
Features to come:
- Theme Support (Different Remote Types)
- Remote Database (Downloadable IR codes to use with your equipment)
- Macro Support
Changelog:
30/07/13 Initial Release 0.4
Thanks:
- Apache14 for reverse engineering the IR Blaster and building the library to use it
- PingPongBoss for the StandOut library.
- Riekr for the italian translations
- antifish for letting me use his database from here
- NeverGone\RU for the russian translations
Please no Feature Requests and Problem reports via PM. Post them here or open a ticket on github (or even better, send me a pull request) , so more people can benefit from what you found out.

I am trying to reverse engineer their format as well as their proprietary database loader. But at the moment it looks rather bleak. I could try to integrate the lirc format from here It is open source and they suport multitudes of remotes, but their list is a little outdated. I also thought about this, but they have no downloadable database and I would have to download and integrate every key.
Does anyone know a got downloadable remote database?
wow! thanks for your efforts! this is what i was waiting for prior installing cm10.2
one question before trying, can i acquire commands from existing remote?
i think i'm gonna try this app this evening anyway

Tried now to clone my Philips soundbar remote but no luck, the signal is not recognized.
That remote was problematic with Sony's apps too but at the end they were working after some trial.
Tomorrow I'll try with some other remote.

i think i've found a good database.it's from this app.the dev has recently uploaded the app's code on git because he will stop developing the app and said that if somebody wants to use his database has to contact him.his database has 45.000 codes.in fact as the app is opensource if you could make this app use apache's library(as it doesn't work on tablet z now) would be perfect.i would have tried but my tablet z hasn't arrived yet.it's ui about selecting device is ideal

Thank you for sharing! I also heard back from antifish, and he allows me to use his database. Next step now is understanding the structure of the different DBs and integrating them into the Application.
Hello,
I am developer for OpenHMD (openhmd.net) and we are currently looking into adding PC support for the LG 360 VR.
We think this can be a very good low cost HMD device for use with other devices other then the original G5.
Though i own a 360VR, i don't have a G5, and we require a pcap dump from the original hardware to reverse engineer the initial communication with the device.
Could some one test if the G5 has usbmon enabled (linux kernel option CONFIG_USB_MON) and make a dump for us plugging in the device, and capturing communication with a app.
Alternatively if this is not the case, the G5 kernel could be recompiled with the CONFIG_USB_MON option to allow for pcap capturing.
Thanks

Great, you have sufficient information from my initial post?
You have experience with these kind of things?
Thanks

I don't. I briefly looked around for a straight forward tutorial for doing the dump but didn't find one.
is your phone rooted?
If so, can you try modprobe usbmon and see if it can load the module?
the general idea is in the linux kernel source at Documentation/usb/usbmon.txt
(xda-developers won't let me post the exact link until i have 10 posts, sorry. I'm an OpenHMD contributor, not an xda dev)
but there's probably going to be some android weirdness to work around.
If you're near Los Angeles, I also have a usb packet sniffer we could try if you want to meet up face to face sometime.
Hi!
I'm interested in more advanced video recording apps like "Filmic Pro" which need a certain level of Camera2 API support to function properly. Could someone with a J3 (2017) please run this free app "Camera2 probe" and tell me if the hardware level support category comes out as "Level 3", "Full", "Limited" or "Legacy", maybe post a screen grab?
Cheers!
Here you go!
I personally love the manual mode thing

Hey, thanks a lot, good to see that their super-budget phone has at least "Limited". While isn't enough for Filmic Pro, other manual camera apps work fine with "Limited". Cheers!
