[patch] Android Shell (mksh) bash_profile replacement

[patch] Android Shell (mksh) bash_profile replacement - Android General

Android default shell is a bit tricky when you want to do customiztaion. So, i just happen to browsing a bit to its source and do a little patch. This is a bit dangerous coz it'll automatically eval the .shinit in /sdcard/ which we know some apps wight r/w that file, use with caution. Tested on x86, 4.4.2. ASUS Zenfone C.
Patch,

Push and replace mksh to android, dont forget to make a backup for original mksh in case things goes wrong.
This mksh will force load .shinit in /sdcard/ (/sdcard/.shinit). example for my .shinit,
Code:
export PATH=/data/local/bin:$PATH
alias bash='bash --rcfile /sdcard/bashrc'
alias gdb='gdb -q'
alias ll='ls -laH'

floating point arithmetic? - hack job workaround now included

is there a way to do floating point arithmetic in terminal?...or would bc binary need to be included since busybox does not have it? as of now you get a syntax error if using fp numbers in expression..or 0 when using division and result is a floating point.
Code:
# echo $(( 1 + 1 ))
echo $(( 1 + 1 ))
2
# echo $(( 1.0 + 1.0 ))
echo $(( 1.0 + 1.0 ))
arith: syntax error: " 1.0 + 1.0 "
# echo $(( 1 / 2 ))
echo $(( 1 / 2 ))
0

sh/bash has no native support for floating point math, so your solution must involve a binary executable. You can either use bc, or you can write a very simple C program and compile it for this platform....
i.e.,
Code:
//math.c
#include <stdlib.h>
#include <stdio.h>
int main (int argc, char ** argv){
float a = atof(argv[1]);
char op = argv[2][0];
float b = atof(argv[3]);
if (op == '+') printf("%f\n",a+b);
else if (op == '-') printf("%f\n",a-b);
else if (op == 'x') printf("%f\n",a*b);
else if (op == '/') printf("%f\n",a/b);
return 0;
}
$ ./math 1.5 + 2
3.500000
$ ./math 1.5 x 2
3.000000
$ ./math 1.5 - 2
-0.500000
$ ./math 1.5 / 2
0.750000
Oh and FYI, don't forget you can use variables in there, i.e.
$ A=1.5
$ B=2
$ OP=/
$./math $A $OP $B
0.750000

Is this the appropriate forum?

Sorry, are you a moderator? :/
And yes, since this is a development matter, I'd say it falls within the DEVELOMPENT section..

thanks for the info. very helpful.

script workaround
i have constructed a workaround for doing fp math for determining partition sizes.
it's not pretty, but it gets the job done.
basically, it goes like this:
1. check to see if the number passed to the function is an integer
2. if not, i search the string for a "."
3. if the search turns up a "." (and units in GB) i break the number into two whole numbers (the integer portion..before the decimal, and the fraction portion after the decimal).
4. do the appropriate math on the integer section.
5. do the appropriate math on the fraction section, then divide by 10^#of digits after the decimal place.
6. add the two numbers together and voila! a hack job, floating point calculation.
Code:
ValidateSizeArg() {
# check for zero-length arg to protect expr length
[ -z "$1" ] && ShowError "zero-length argument passed to size-validator"
SIZEMB=
ARGLEN=`expr length $1`
SIZELEN=$(($ARGLEN-1))
SIZEARG=`expr substr $1 1 $SIZELEN`
SIZEUNIT=`expr substr $1 $ARGLEN 1`
# check if SIZEARG is an integer
if [ $SIZEARG -eq $SIZEARG 2> /dev/null ] ; then
# look for G
[ "$SIZEUNIT" == "G" ] && SIZEMB=$(($SIZEARG * 1024))
# look for M
[ "$SIZEUNIT" == "M" ] && SIZEMB=$SIZEARG
# no units on arg
[ -z "$SIZEMB" ] && SIZEMB=$1
# check if SIZEARG is a floating point number, GB only
elif [ `expr index "$SIZEARG" .` != 0 ] && [ "$SIZEUNIT" == "G" ] ; then
INT=`echo "$SIZEARG" | cut -d"." -f1`
FRAC=`echo "$SIZEARG" | cut -d"." -f2`
SIGDIGITS=`expr length $FRAC`
[ -z "$INT" ] && INT=0
INTMB=$(($INT * 1024))
FRACMB=$((($FRAC * 1024) / (10**$SIGDIGITS)))
SIZEMB=$(($INTMB + $FRACMB))
# it's not a valid size
else
ShowError "$1 is not a valid size"
fi
# return valid argument in MB
FUNC_RET=$SIZEMB
}

I was a basic/qbasic/gwbasic programmer in my younger days (like 12-14 yrs old)...
I feel ashamed that I have no idea of what this stuff is anymore. Thank God for guys like you.

j4fs driver is now OpenSource

Big news for every hacker on Samsung devices! j4fs driver is now OpenSource Enjoy: http://bit.ly/jatK1c

http://romkitchen.org/sgs/?s=home
Someone care to explain the benefits, if any, of this? My understanding from what little i read is it will help with kernal development on a decent number of samsung devices.
Edit: as in should i be "super excited", "meh", or "cool beans".

second that question .. does this help us?

Would this driver be the one that controls download mode?
Sent from my GT-I9000 using XDA Premium App

Maybe this?
added: Should have checked supercurio's github
Samsung v1 GT-I9100 sources: [common] param.lfs/j4fs driver (communication with bootloader), now OpenSource, yay!

google :
j4fs...
its a filesystem.... FACT
So my GUESS...
a driver for a filesystem...
like ext4 and fat drivers for handling our other storage..
a new filesystem for us to tweak the crap out of and use..?
though ive been wrong before. that is only a logical conclusion not a factual statement

according to the post above you this may be the file system used for the bootloaders on the sgs2 so it would help those folks when hacking.

J4FS porting released
If someone is still interested I've just finished the porting of the J4FS on 3.1.x kernel adding support for normal "block device" (for loopback image mounting).
movitool.ntd.homelinux.org/trac/movitool/wiki/j4fs
Hope this can help...
Ceers
Nitro

And another tool (standalone) to extract j4fs/lfs images (eg. param.lfs).
Note: it only extracts - if you want to modify an image you'll have to use the kernel module from the post above (or a hexeditor and some cleverness).

dunno for what the driver/partition is used, had troubles (device freeze) with custom kernel an the original module from my GT-I9100 (ICS)
as note: device boots and working without the j4fs module in initramfs...
just for fun a little patch for kernel 3.0.15, just read operation tested.

[Q] Compiling gcc and toolchain for use ON android device

Hello all. I have built the android-ndk-r9d toolchain on my Ubuntu machine, and it will compile a few things like nmap and perl just fine with some tweaking (I forgot the links but there are projects that give the options to use when compiling these). But I haven't seen any successful compilations of more recent versions of gcc with bionic.
I did some digging around in spartacus' terminal-ide project, the point of which is to have java, vim, gcc for use on the device itself, I found that gcc was version 4.4.0. I have tried to reach him via email to see what ./configure settings he used, but to no response.
Has anyone else attempted this, to build android gcc in versions more recent than 4.4.0 for compiling software on the device? What configure settings have you tried, and how much have you modified the gcc source code itself? Or is everyone content to build other projects using their regular Linux box?
My device in question is a nexus 5, which has more than enough CPU power to do this, to quell any concerns people will have to that end.

Well, I had a day free yesterday and tried everything again, and I believe I hit the same stopping point error after correcting several others. Only this time, I made an actual script and patchfiles to handle everything to make this more organized. Again has anyone attempted to do this?
First, the script.

Patched kernel CVE-2016-5195 (aka "Dirtycow")

For those of you wanting to patch your device asap, you can download my patched kernel. This is built from the latest Samsung standard sources with a couple of minor config changes, namely the ability to change SELinux enforcing mode as boot and runtime, removal of DM_VERITY and KNOX_KAP and a couple of IPv6 / QoS items (netfilter targets, qdiscs). The full config diff is below.
If you want to use this kernel you will need to create your own bootimage. On your device
Code:
# dd if=/dev/block/platform/15540000.dwmmc0/by-name/BOOT of=/sdcard/boot.img
Unpack the boot image (you can use this tool. In the unpacked folder, replace the boot.img-zImage with the new zImage from the zip file you downloaded. Recreate the bootimage with the mkbootimg tool (all the command line args you need to supply will be in the files that the unpackbootimg command created - just plug these values back in).
Now you can adb push the new boot.img back to your device and flash it using the reverse operation
Code:
# dd if=/sdcard/boot.img of=/dev/block/platform/15540000.dwmmc0/by-name/BOOT

I understand that. N910CXXU2DPI7 appears to be the latest. Which is why my question was simply, which one did he use, to verify that was it.

Yes, correct. I used the latest vanilla Samsung sources N910CXXU2DPI7. You can download them directly from Samsung. I've supplied the patch and the config diff, so everyone can precisely replicate the linked binary kernel version if they wish.

This helps thanks a ton. I've really never attempted to compile a kernel for android. That's my last frontier.
I've done Linux over 10 years ago, I've just been content with using others.
They've all been great, but the only thing that was missing was the Revoke USB debugging authorizations on most of the custom ones.
I'd have to flash back to stock if ADB lost its mind and wouldn't recognize the phone.
Good stuff, great work. Much appreciation. Hope you stick around !

If you want to use ADB on this kernel and you're booting with SELinux in enforcing mode, you'll need to first run a terminal and execute
Code:
$ su
# setenforce 0
If you don't do this, ADB will appear not to work or even recognize the device.
When you're done, just setenforce 1 again. Of course, depending on how your ramdisk is setup, this may not be necessary but it's worth knowing if you run into apparent problems with ADB.

ADB usually works fine. After reflashing and moving to a new machine ADBKeys is usually hosed.
So Revoke USB debugging authorizations is not under Developer Options to reset under some kernels, but it is under stock and it was after I applied yours. Which was cool.
It doesn't happen a lot just enough to be annoying.

This is nice.. @dl12345 I suggest make a flashable kernel..
Im not seeing any updated kernel right now specially for n910c device,.. no more kernel devs

[KERNEL][PI7 v1.5][6.0.1][TW] talexop - Note4 N910C Permissive
N910C_PI7_6.0.1_talexop_v1.5.zip
Came out Nov 2
Hoping sources will be out soon

The thing with a flashable kernel is that everyone has a different ramdisk, so making something that fits all sizes is tricky. I figured it better to just let people use their existing ramdisk and so they won't notice any real change, regardless of the ROM they're using.

I saw your post in talexop's thread... are you able to confirm if dm verity is disabled with Permissive?
Im not really satisfied with systemless root, i want system mode root.. but it requires custom kernel with dm verity disabled.

Yes, CONFIG_DM_VERITY is disabled on this kernel as is CONFIG_KNOX_KAP. I run this kernel in enforcing mode (you can switch SELinux on or off with a boot command line parameter, or with the setenforce command).

I compiled a kernel and mine is doing the same thing. But I think I found the fix. I hope. Kernel's running good I think.
But it's my first one ever and I'm still tickering with things.
It will be 70-80% stock. IF I release it it won't be until the end of the month at least.

These are all ramdisk related problems, and one of the reasons I just posted a link to a kernel rather than full boot image.
This wifi issue is a known problem caused by using secure_storage with a custom kernel or ROM. Your default.prop in your ramdisk should turn off securestorage
Code:
ro.securestorage.support=false
I'd also suggest the following edits in default.prop which are related to adb. Just search them here on XDA. There's lots of info
Code:
ro.secure=0
persist.service.adb.enable=1
persist.service.debuggable=1
ro.debuggable=1
ro.adb.secure=0
persist.sys.usb.config=mtp,adb

I do not think you can change to enforcing... It is only permissive. Are you sure it changed?

Build Aosp Extended on Ubuntu 18.04 (Bionic Beaver)

Build AOSP on ubuntu 18.04 Bionic Beaver
1. I suggest using screen when build so install it
sudo apt-get install screen
2. Add this line to /etc/apt/sources.list
deb http://cz.archive.ubuntu.com/ubuntu trusty main
3. Update repository list
sudo apt-get update
4. Install dependencies for building
mkdir -p ~/bin
wget 'https://storage.googleapis.com/git-repo-downloads/repo' -P ~/bin
chmod +x ~/bin/repo
sudo apt-get install openjdk-8-jdk android-tools-adb bc bison build-essential curl flex g++-multilib gcc-multilib gnupg gperf imagemagick lib32ncurses5-dev lib32readline-dev lib32z1-dev libesd0-dev liblz4-tool libncurses5-dev libsdl1.2-dev libssl-dev libwxgtk3.0-dev libxml2 libxml2-utils lzop pngcrush rsync schedtool squashfs-tools xsltproc yasm zip zlib1g-dev git-core python
5. Setup git
git config --global user.name "your name"
git config --global user.email "your email"
6. Add repo path and enable ccache
nano ~/.bashrc
Add these lines to the bottom of bashrc
export PATH=~/bin:$PATH
export USE_CCACHE=1
export LC_ALL=C
Then to enable these use command
source ~/.bashrc
7. Make working directory
mkdir ~/android
cd ~/android
8. Initialise repo source (In this example we will use AospExtended Oreo )
repo init -u git://github.com/AospExtended/manifest.git -b 8.1.x
9. Sync repository (this could take a while depending on your internet connection, replace x with number of cores available remember to leave some free for system processes)
repo sync -c -jx --force-sync --no-clone-bundle --no-tags
10. Configure how much drive space ccache can use (I recommend 25-30gb)
prebuilts/misc/linux-x86/ccache/ccache -M 25G
11. Configure how much ram Jacks server can use (I recommend at least 8gb but the more resources you use the faster it will build)
export ANDROID_JACK_VM_ARGS="-Xmx8g -Dfile.encoding=UTF-8 -XX:+TieredCompilation"
12. Download device specific trees
Kernel tree
Device tree
Device Common Tree
Vendor Tree
these are specific to each device so you need ones that match your device
13. Build Initialise
. build/envsetup.sh
lunch aosp_devicename-userdebug
An example for Xiaomi Mi Max 2 codename (oxygen)
lunch aosp_oxygen-userdebug
14. Then to start building (replace x with available cores again the more cores made available the quicker it will compile)
make aex -jx

Build AOSP on ubuntu 18.04 Bionic Beaver
1. I suggest using screen when build so install it
sudo apt-get install screen
2. Add this line to /etc/apt/sources.list
deb http://cz.archive.ubuntu.com/ubuntu trusty main
3. Update repository list
sudo apt-get update
4. Install dependencies for building
mkdir -p ~/bin
wget 'https://storage.googleapis.com/git-repo-downloads/repo' -P ~/bin
chmod +x ~/bin/repo
sudo apt-get install openjdk-8-jdk android-tools-adb bc bison build-essential curl flex g++-multilib gcc-multilib gnupg gperf imagemagick lib32ncurses5-dev lib32readline-dev lib32z1-dev libesd0-dev liblz4-tool libncurses5-dev libsdl1.2-dev libssl-dev libwxgtk3.0-dev libxml2 libxml2-utils lzop pngcrush rsync schedtool squashfs-tools xsltproc yasm zip zlib1g-dev git-core python
5. Setup git
git config --global user.name "your name"
git config --global user.email "your email"
6. Add repo path and enable ccache
nano ~/.bashrc
Add these lines to the bottom of bashrc
export PATH=~/bin:$PATH
export USE_CCACHE=1
Then to enable these use command
source ~/.bashrc
7. Make working directory
mkdir ~/android
cd ~/android
8. Initialise repo source (In this example we will use AospExtended Oreo )
repo init -u git://github.com/AospExtended/manifest.git -b 8.1.x
9. Sync repository (this could take a while depending on your internet connection, replace x with number of cores available remember to leave some free for system processes)
repo sync -c -jx --force-sync --no-clone-bundle --no-tags
10. Configure how much drive space ccache can use (I recommend 25-30gb)
prebuilts/misc/linux-x86/ccache/ccache -M 25G
11. Configure how much ram Jacks server can use (I recommend at least 8gb but the more resources you use the faster it will build)
export ANDROID_JACK_VM_ARGS="-Xmx8g -Dfile.encoding=UTF-8 -XX:+TieredCompilation"

If you wish to use with another rom this guide add
Code:
sudo apt install selinux
.

If you get an error mentioning STATIC_LIBRARIES/libedify_intermediates/lexer.cpp make sure to also add
"export LC_ALL=C"
in your ~/.bashrc file.

@eva0034 I followed this guide but instead i replaced repo init 8.1.x with 7.1.1 because my device only has nougat support. I get stuck in repository sync at 99% every time. When I abort it shows failure to fetch snapdragon camera.
I posted on aex telegram and they advised me to delete snapdragon camera in repo/manifest xml.
I can't find this folder or file anywhere. Any idea?

this caused to my machine to hang at ubuntu screen at reboot. I entered recovery mode and used sudo apt-get remove selinux but it still hangs.
any idea?

Don't actually install SELinux. You can build other ROMs just fine without it. (I have only really tried Lineage and Dirty Unicorns though.

Hey there eva0034. I appreciate you writing this up for people!

And this is what it looks like when I run the envsetup.sh:

Wondering if you or anybody else has any ideas as to how to solve this? Do I have to add something to "aex_manifest.xml" in local_manifests perhaps? Thank you to anybody who may be able to help. Am new to this
Edit: Got past the above issues by using a roomservice.xml file and get to around 6% of actual compiling but it throws an error when it gets to building the kernel. I give up for now... too hard for my tiny brain

not doing anything after "make aex -j2"
It just show it at the bottom of the command line and does nothing

Thanks

Maybe if you typed the proper command it might work
Finally to build:
. build/envsetup.sh
lunch aosp_device_codename-userdebug
mka aex -jx

Can someone tell me how to install vendor tree and kernel? i use A605K device, and i researched a bit.
but i still don't know how to install kernel tree and vendor tree. i know device tree and common tree can be installed by put device name folder in sourcefolder/devices folder, and how can i build vendor tree and kernel tree?

Since there is no current developer for your device, you are going to have to do create all the trees and kernel all by yourself..

Where the android source code is stored in ubuntu 18.10?

can you tell more about these steps. For example, where I should download Kernel tree, to which directory? Or where I should download device tree and other components that you mention?

After a few searches, I thought that must be declared in the BoardConfig.mk of the device tree. But I couldn't figure out.
Any help would be appreciated.

What's the use of screen package?

I did the following but when i do make aex -j$(nproc) it gives this error
ninja: error: unknown target 'aex', did you mean 'dex'?
