WIP: KaKaroToKS - lv1 syscalls dumped!

[Dertyp]

KaKaRoToKS author of PSFreedom and the famous PL3 payloads, has been busy still poking around the inside of the PS3 console!

For Those Of You Who Are Asking What This Is:

level-1 syscalls are used to call hypervisor functions. On a PS3 the hypervisor is known as as “lv1″ (level1) since it is the lowest level that runs directly on top of the hardware. The operating system is executed on top of this and is known as “lv2″ (level2). The two common operating systems are GameOS which PS3 games run on, and OtherOS which is usually used to run linux. Since both OSes run on top of the same lv1 hypervisor, they use the same set of hypercalls which has been partially documented here.

KaKaRoToKS Recent Tweets:

FINALLY able to dump (over eth) all lv1 calls!! Will push it soon!

To everyone misunderstanding: no lv1 access, all I did was be able to dump the "call trace" of lv1 hypercalls. same as payload_dump_syscalls

And Finally What Does These All Mean To Us Right Now!

This is work-in-progress, once KaKaRoToKS has finished his poking around the dumps, and detailing the info on his GIT, I will update this thread, even after he is done, it will take some time for various PS3 developers to study all this new information, before it will help out the "end-user" but it is another big step forward in the daily forever-changing and growing-fast PS3 Scene World!

***Update2***

Well, KaKa let us know via Twitter, that his home server can´t handle so much traffic. So user ieder-zijn-meis (thx 4 that) brougt the file 2 one-klick-hosters to keep KaKa´s server available for other stuff.

***Progress Update***

KaKaRoToKS via Twitter

Released the hypercall tracer payload! Also merged syscall tracer, and a payload that traces hypercalls+syscalls.
But the hvsc+sc payload has race conditions because of high eth load.. Also added a payload that traces vuart access and dumps the buffers

Now that is some fortunate news.
Let's hope that all the peeps who said the ps3 scene is dead packed up and left.

Knowing Kakaroto, it's to be trusted. That's good news.
