HackCon 2016 - angry-reverser does not work about angr-doc HOT 5 CLOSED

i met the same problem,
the amd64 syscall table in simos.py, There is no Syscall to No. 101(ptrace), have anyone solve it? and How do I hook a system calls such as ptrace in angr.

from angr-doc.

Did you solve it? I met the same problem.

from angr-doc.

My guess is that this example was not verified when we checked it in, and the author had implemented their own ptrace stub.

There is actually ptrace support being worked on right now (angr/simuvex#78). You can try to pull that into simuvex, and add the right entry to the table in simos.

An alternative would be to add BYPASS_UNSUPPORTED_SYSCALL to the state options -- it might allow it to get over that hurdle (at the cost of unnecessary symbolic data in the state).

thank you very much @zardus
