I have a samsung galaxy nexus and I am using ubuntu 12.04...

Unfortunately I could't see any SeAndroid when I lunch the adb shell
getenforce, so I decided to try again.

this is my procedure:
- initialize repo with the master version
- add the master local_manifest.xml in the .repo folder
- sync
- build a modified kernel with the necessary support for SELinux

export PREFIX=/path/to/your/aospclone
cd $PREFIX/kernel/samsung
make ARCH=arm tuna_defconfig
make ARCH=arm CROSS_COMPILE=$PREFIX/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin/arm-eabi-

- make HAVE_SELINUX=true

Now the device tries to boot but I can only see an horizontal line on the
screen.
However if I try to interrogate the device with the adb shell getenforce, I
can see that it is in a permissive mode.
What is wrong??

When I compiled AOSP the first time I had the same problem with the screen
and I solved with additional hardware-related proprietary libraries, that
are here
https://developers.google.com/android/nexus/drivers?hl=da#maguroimm76d
I used this one: Galaxy Nexus (GSM/HSPA+) binaries for Android 4.0.4
(IMM76D to IMM76L).
I also tried to add these libraries but it doesn't work yet!

Can anyone help me?

Hi,
sorry for all the mails!
I installed SeAndroid but I have some problems.
- the camera is not working (is it normal?)

i would like to install other applications but I really didn't get how to
do that.
should I install the application and then define new policies?
How to define the policies?

then I notice that I have some residual denials to address in my policy.
I hope I will find a way and I am really sorry but I am a beginner!

Thanks in advance,
Alexandra

RE: Welcome to selinux

[Radzykewycz, T (Radzy)]

Hi Alexandra

The camera uses proprietary components, which are not available in source form from the standard repo.  You need to install the binary proprietary components befroe building.  There are several other things, which also need proprietary binary components.

You can download and use the proprietary components from Google, but they are not complete.  These are at https://developers.google.com/android/nexus/drivers .  I'm not sure that the camera itself is included in these files.

Another option: look on the WEB for instructions about how to fetch the proprietary bits from the device running the stock images.  This can be more complete that the Google files.

Enjoy!

                                                              -- radzy

The omap kernel with the tuna_defconfig is the one to use for Galaxy
Nexus.  Commands to execute from the seandroid directory:
cd kernel/omap
make ARCH=arm tuna_defconfig
make ARCH=arm CROSS_COMPILE=$PREFIX/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin/arm-eabi-

That's not SE Android related - it is a general AOSP issue; see
discussions on android-building.  The extract-files.sh script from the
per-device directory may help you.

Yes, although you shouldn't need a new policy for each app; policy is
written in terms of types (equivalence classes).

> How to define the policies?

If using the middleware MAC support, you would amend the
external/mac-policy/mac_permissions.xml configuration.  For the SELinux
policy, you would possibly amend external/sepolicy/seapp_contexts if you
want to label the app differently and you might amend the rules in
external/sepolicy/app.te.

Best thing to do is to post the denials and let people help you
understand what they mean and how to start addressing them.  Once you've
done it for a few denials, you'll pick it up.

I tried to install application from the google play website directly from
the phone but it is not working.

So I installed directly from the apk... some of them are working, others
are not... but how to find legitimate apk?

I am not using the MAC support.

How to get the formal meaning of the files? I tried to look for it...

Not sure what you mean by "not working" above.  You have to separately
install the gapps, but they work for us.  Enforcing or permissive?

> How to get the formal meaning of the files? I tried to look for it...

seapp_contexts is only "documented" by the inline comments at the
moment.  The SELinux policy language is documented in a variety of
places, including books (e.g. SELinux by Example, the SELinux Notebook),
wiki pages (e.g. http://selinuxproject.org/page/PolicyLanguage), and
technical reports (e.g.
http://www.nsa.gov/research/selinux/docs.shtml#tech).

No avc messages in the output of adb shell dmesg or adb logcat?

Thanks for the suggestions, the phone is now working in permissive mode.
I would like to set the enforcing mode but I still have some residual
denials.

Are you building your system.img with the gapps? Are you adding the gapps
afterwards (after the biuld and flash)?
If afterwards, the denials specific to the gapps below would explain that.
Try baking the gapps into the system
image before the system.img is built.

Yes, you need to work through those denials and resolve them by:
- Labeling unlabeled files on your device via restorecon,
- Labeling device nodes that are left in the "device" type with a more
specific type to permit access by adding entries to file_contexts or the
device/<vendor>/<board>/sepolicy.fc file.
- When appropriate, adding allow rules to the .te files in sepolicy or
to a device/<vendor>/<board>/sepolicy.te file to permit the access.

You can use audit2allow as described on the wiki to generate raw allow
rules, but often you will want to fix the labels rather than allow the
permission on the existing types.  And when you add allow rules, you
shouldn't just add the ones emitted by audit2allow but should instead
use them as a guide and seek to generalize them using the macros defined
in *_macros.  Look at the existing .te files for examples.

How to do that? I have a .zip file with some folder inside (system,
optional and meta-data )

Doing a restorecon might be the easiest solution as described by Stephen
Smalley. However, every time
you reflash your phone with new images you'll have to do a restorecon on
those apps. If you want to include
the gapps into your build harness you'll need to modify device specific
makefiles to PRODUCT_COPY_FILES
from the gapps directory you have downloaded. Best bet is to look at a
current working example under the 'vendor'
directory for the specific device your building. Then just create a
vendor/google to mimic its structure.

I tried to build with the gapps, I created a folder vendor/google and tried
to reproduce the same order of the vendor/samsung/ folder.

The problem is that when I try to build it says:

"build/core/product_config.mk:195: *** device/samsung/maguro/full_maguro.mk:
malformed COPY_FILE "vendor/google/maguro/proprietary/".  Stop.

I tried to investigate without success, so I decided to try to use the
restorecon. is it needed to be root?
on which files do I need to use restorecon? how?

Thanks

You'll not only have to be root, but you'll also need to remount your
system partition (android mounts it read only).
I would try:
adb shell
su
mount -o rw,remount </dev/block path for your device> /system
restorecon -R /system

My phone is now is in enforcing mode but I can not install anything.
I tried from google play but after the download, when it tries to install
says:
"the download url is not valid"

Do I have to change the policies? I saw the app.te files in
external/sepolicy in the build directory, but where can I fine the same
file on the phone?
Do I need to rebuild and reflash every time I change the policies?

Check for avc denials.  With regard to updating the policy, you can
modify the policy source files, do a 'make sepolicy' to regenerate the
kernel policy file, do an 'adb push
out/target/product/<device>/root/sepolicy.24 /data/system/' and do a
'adb shell su 0 setprop selinux.loadpolicy 1' to reload policy
from /data/system rather than having to reflash the system partition
each time.

Re: SE Android (Was: Re: Welcome to selinux)

[William Roberts]

I dont see any denials being cuase be gapps so thats ok.

What version if SEAndroid are you running?

You can pipe your denial logs (dmesg) through a tool called
audit2allow to get a more concise reading. It often helps to make sens
of things

adb shell dmesg | audit2allow

It looks like some things are not getting labeled properly
#============= mediaserver ==============
allow mediaserver device:chr_file { read write ioctl open };
allow mediaserver system_data_file:dir { read open };
allow mediaserver system_data_file:file open;

We dont care about shell
#============= shell ==============
allow shell device:chr_file { read write getattr ioctl };

We may need to allow this in the policy...need to put more thought in it.
#============= system ==============
allow system proc:file write;
allow system rild:unix_stream_socket connectto;

Denials explained:
allow system proc:file write is from this denial:
<5>[   24.782653] type=1400 audit(1344517139.820:6): avc:  denied  {
write } for  pid=404 comm="LocationManager" name="mcspi1_cs3_ctrl"
dev=proc ino=4026532651 scontext=u:r:system:s0
tcontext=u:object_r:proc:s0 tclass=file
This should be fixed on tuna/maguro device...

allow system rild:unix_stream_socket connectto is from this denial
<5>[   25.809204] type=1400 audit(1344517140.843:7): avc:  denied  {
connectto } for  pid=460 comm="GpsLocationProv"
path=004D756C7469636C69656E74 scontext=u:r:system:s0
tcontext=u:r:rild:s0 tclass=unix_stream_socket
This should be fixed..

Media server denies
<5>[   26.586181] type=1400 audit(1344517141.625:8): avc:  denied  {
read } for  pid=175 comm=42696E646572205468726561642023
name="rproc_user" dev=tmpfs ino=2868 scontext=u:r:mediaserver:s0
tcontext=u:object_r:device:s0 tclass=chr_file
<5>[   26.586364] type=1400 audit(1344517141.625:9): avc:  denied  {

name="rproc_user" dev=tmpfs ino=2868 scontext=u:r:mediaserver:s0
tcontext=u:object_r:device:s0 tclass=chr_file
<5>[   26.602386] type=1400 audit(1344517141.640:10): avc:  denied  {
write } for  pid=175 comm=42696E646572205468726561642023
name="rpmsg-omx1" dev=tmpfs ino=3045 scontext=u:r:mediaserver:s0
tcontext=u:object_r:device:s0 tclass=chr_file
<5>[   26.602783] type=1400 audit(1344517141.640:11): avc:  denied  {
ioctl } for  pid=175 comm=42696E646572205468726561642023
path="/dev/rpmsg-omx1" dev=tmpfs ino=3045 scontext=u:r:mediaserver:s0
tcontext=u:object_r:device:s0 tclass=chr_file

The problem here comes from labeling:
/dev/rpmsg-omx1 is not labeled properly but should be, it was fixed in
external/sepolicy commit ee5f4005

Make sure your seandroid is up to date, I have a feeling you need to
update your local_manifest.xml file and do a new repo sync..

I am also forwarding this to the public mailing list, so others can
learn from this and answer problems before they arise. I hope this
helps, and for now on direct these types of questions back to the
mailing list to help others out.

My version was a bit old so I decided to update it.

Unfortunately it cannot succeed, this is the error:
*update-apt-xapian-index has closedReceiving objects:  82% (4843/5898),
299.71 Mifatal: The remote end hung up unexpectedly65 MiB | 411 KiB/s    *

*^Cerror: Cannot fetch device-samsung-tuna77 MiB | 400 KiB/s  *
I am using the master version. If I look into the folder it did not write
anything inside...

Thanks for your help

Previously discussed on list (subject was "Cloning Android repo's from
bitbucket").  The problem is that the tuna project is very large and
apparently git clone via https falls over for such a large project from
bitbucket.org.  Options for resolving:

1) Switch to using ssh access.  Requires creating a registered bitbucket
account first with ssh keys.  To use this approach, create an account on
bitbucket.org, upload your public ssh key, and switch to the master-ssh
branch of the manifests project to get the local_manifest.xml file using
ssh access.

-or-

2) Do your repo sync first without the local_manifest.xml file (i.e.
just download AOSP), then move the local_manifest.xml file into place
and run repo sync again.  This should fetch the original projects from
AOSP which in turn should reduce what it has to fetch from bitbucket.org
to just our changes.

When I try to check out the aosp, it fails with this error

Any idea?

No, never seen that one.  Try creating a fresh client in an empty
directory (without any .repo subdirectory) from AOSP.  Might want to
also make sure you are using an up-to-date version of repo.

[Radzykewycz, T (Radzy)]

When I've seen similar problems in the past, it was usually (always?) caused because a git pull or git clone had been interrupted at the wrong place.  My normal workaround is to remove the corrupted project.  In this case, I think that may be "rm -rf .repo/projects/dalvik.git dalvik"

Thank you very much!
I  tried to remove the .repo folder but i did not solve.
I solve checking out all the source from the bitbucket folder.
