Inject custom code or data into running process

[Sayutin Dmitry]

Hello, how one should inject code or data into allready running process?

There is no need to start code execution at this point, but it should appear in it's virtual memory.

Moreover, i want this data to persist across execve's or clone's (probably can be implemented as hook on appropriate kernel methodes)

(If you want to know motivation for this -- I want to implement some new idea on sandboxing).


Thanks in advance, Sayutin Dmitry <cdkrot at yandex.ru>
