[$] Verifying the BPF verifier's path-exploration logic

Date:
Tue, 27 May 2025 19:15:46 +0000

Description:
Srinivas Narayana led a remote session about extending Agni to prove the 
correctness of
the BPF verifier's handling of different execution paths as part of the Linux 
Storage,
Filesystem, Memory Management, and BPF Summit. The problem of ensuring the
correctness of path exploration
is much more difficult than the problem of
ensuring the correctness of arithmetic operations
(which was the subject of the previous session ), however. Narayana's plan to
tackle the problem makes use of a mixture of specialized techniques  and may
need some assistance from the BPF developers to make it feasible at all.
