Talk:Research: Pwnage Patches

Kernel and ramdisk patches

Anyone care to share what is patched?

yup

ramdisk:

asr - patch out rootfs SHA1 check

restored_external - patch wiping routine

kernel:

haven't looked into this, but there are four patches, at least some of them are for codesign and apparently one of them has to do with virtual memory mapping.

Thanks

Do you know how the new codesign is added yet? I notice you think they didn't use ldid. It seems that the second patches to asr and restored are codesign (from what I can tell when 2.1 and 2.2 files are compared), but I don't see any in the kernel, they're all simple.
