[$] Allowing BPF programs more access to the network

Date:
Wed, 28 May 2025 15:33:01 +0000

Description:
Mah Tardy led two sessions about some of the challenges that he, Kornilios 
Kourtis,
and John Fastabend have run into in their work on Tetragon (Apache-licensed 
BPF-based security monitoring software)
at the Linux Storage, Filesystem, Memory Management, and BPF Summit. The 
session
prompted discussion about the feasibility of letting BPF programs
send data over the network, as well as potential new kfuncs to let BPF 
firewalls
send TCP reset packets. Tardy presented several possible ways that these could
be accomplished.
