Hi,
What does "security monitor style IPC permissions" mean? Can it be found in current Fiasco release?
Yes, it can be found in Fiasco. Tasks can be started in "monitored" mode which means that they only possess rights to communicate with themselves, their creators and the NIL thread. Every other IPC will raise a capability fault which is sent to a user-defined capability fault handler. The handler may then act upon this fault by mapping an IPC right to the faulting task, if it possesses this right itself. Whenever this right has been mapped, no more capabilty faults will occur until the right is revoked at a later point in time.
Where can I find information about Nova and Robin? Are there any English documentation?
Maybe start at http://robin.tudos.org/ .
