Automated Formal Verification of Software Network Functions

Formally verifying the correctness of software is necessary to merit the trust people put in software systems. Currently, formal verification requires human effort to prove that a piece of code matches its specification and code changes to improve verifiab ...

A Formally Verified NAT

George Candea, Aikaterini Argyraki, Solal Vincenzo Pirelli, Luis David Figueiredo Mascarenhas Moreira Pedrosa, Arseniy Zaostrovnykh

We present a Network Address Translator (NAT) written in C and proven to be semantically correct according to RFC 3022, as well as crash-free and memory-safe. There exists a lot of recent work on network verification, but it mostly assumes models of networ ...

Automated Verification of Network Function Binaries

George Candea, Aikaterini Argyraki, Solal Vincenzo Pirelli

Formally verifying the correctness of software network functions (NFs) is necessary for network reliability, yet existing techniques require full source code and mandate the use of specific data structures. We describe an automated technique to verify NF b ...

A Formally Verified NAT Stack

George Candea, Solal Vincenzo Pirelli, Arseniy Zaostrovnykh

Prior work proved a stateful NAT network function to be semantically correct, crash-free, and memory safe. Their toolchain verifies the network function code while assuming the underlying kernel-bypass framework, drivers, operating system, and hardware to ...

A Formally Verified NAT Stack

George Candea, Solal Vincenzo Pirelli, Arseniy Zaostrovnykh

Prior work proved a stateful NAT network function to be, crash-free, memory safe and semantically correct [29]. Their toolchain verifies the network function code while assuming the underlying kernel-bypass framework, drivers, operating system, and hardwar ...

Verifying Software Network Functions with No Verification Expertise

George Candea, Aikaterini Argyraki, Solal Vincenzo Pirelli, Luis David Figueiredo Mascarenhas Moreira Pedrosa, Rishabh Ramesh Iyer

We present the design and implementation of Vigor, a software stack and toolchain for building and running software network middleboxes that are guaranteed to be correct, while preserving competitive performance and developer productivity. Developers write ...

Performance Contracts for Software Network Functions

George Candea, Aikaterini Argyraki, Solal Vincenzo Pirelli, Luis David Figueiredo Mascarenhas Moreira Pedrosa, Arseniy Zaostrovnykh, Rishabh Ramesh Iyer

Software network functions (NFs), or middleboxes, promise flexibility and easy deployment of network services but face the serious challenge of unexpected performance behaviour. We propose the notion of a performance contract, a construct formulated in ter ...

A Simpler and Faster NIC Driver Model for Network Functions

George Candea, Solal Vincenzo Pirelli

The advent of software network functions calls for stronger correctness guarantees and higher performance at every level of the stack. Current network stacks trade simplicity for performance and flexibility, especially in their driver model. We show that p ...
