iasimage

iasimage is a utility program for creating Intel Automotive Service (IAS) images, a binary file format understood by bootloaders to load and initialize Operating Systems or Hypervisors.

iasimage supports the following features:

• Create an image (including kernel cmdline, kernel, hypervisor binary etc.)
• Attach a signature to an IAS image
• Extract components from an IAS image

Examples

Create an IAS image

iasimage create -o iasImage -i 0x30000 cmdline.txt bzImage initrd

Create a multi-file IAS image of type #3 with default page alignment:

iasimage create -o iasImage -i 0x30000 cmdline.txt bzImage initrd acpi Firmware1.bin --page-aligned

Create a multi-file IAS image of type #3 given page alignment:

iasimage create -i 0x40000 cmdLine.txt elf1.bin cmdLine2.txt elf2.bin -o test_image.img --page-aligned=2

Default page alignment values for multi-file images are:

• for type #3 alignment is 5
• for type #4 alignment is 4
• for type #10 alignment is 2

Sign an IAS image

iasimage sign -o iasImage_signed -s rsa.sig -k pub_key.pem iasImage

Create a signed IAS image with a private key (for development purposes only).

iasimage create -o iasImage -i 0x30300 -d priv_key.pem cmdline.txt bzImage initrd

Extract components from an IAS image

iasimage extract iasImage

iasimage's Issues

Support new image types

Add code coverage

Error running iasiamge v0.0.1

$ iasimage --help
File "/usr/bin/iasimage", line 41
from future import print_function
^
SyntaxError: from future imports must occur at the beginning of the file

Looks like there are two 'string sections' (i.e. """) before the import future

Refactor CRC code

Add pylint

Stitching no work properly when add in additional parameter in cmdline

Having issue went add in pad1 and splash.data in cmdline. After stitch iasImage that generated will contain this both parameter. However, now it able to get 1st parameter and 2nd will be missing after the stitching.

expected cmdline:
console=ttyS2,115200n8 root=/dev/mmcblk0p1 quiet console=tty0 console=ttyS0,115200n8 init=/usr/lib/systemd/systemd-bootchart initcall_debug pad1=0xddc@0x7aaa1224 splash.data=0x1fa4fc@0x7aaa2000

Issue cmdline:
console=ttyS2,115200n8 root=/dev/mmcblk0p1 quiet console=tty0 console=ttyS0,115200n8 init=/usr/lib/systemd/systemd-bootchart initcall_debug pad1=0xddc@0x7aaa1224
(one of the parameter is missing)

python2 generated image does not work

Able to support RSA4096 signature?

I see signature length is only 256 byte. Does it mean iasimage cannot support RSA4096? If yes, not sure if there's plan to support it?

Add custom ACPI table to image

Hi,
How to add custom acpi table to finally image? I need add my own acpi table to ClearLinux image, but I can't see the documentation anywhere
