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.

patches

patches to asr and restored are the patches i listed above, and patches for the hashes so that they will run. when i say in the kernel codesign is patch, then it wil patch out the need for code to be signed, but apparently it was determined that the sha1 hash check was too annoying to patched as it would always be changing, so they just rehashed asr and restored, not codesign, just rehashed.
