Subject: [PATCH v2 0/2] udp: add guest-to-remote traceroute
Date: Thu, 27 Mar 2025 12:51:53 -0400 [thread overview]
Message-ID: <20250327165155.3354811-1-jmaloy@redhat.com> (raw)
We add support for UDP traceroute in the tap-sock direction.
More will follow when this one is settled.
---
v2: - Added ttl/hop_limit as flow selection criteria
- Using ancillary data instead of setsockopt() to
pass on ttl/hop_limit.
- Added support for IPv6
