Subject: [PATCH v3 0/2] Reconstruct ICMP headers for failed UDP connect
Date: Wed, 19 Feb 2025 14:30:05 -0500	[thread overview]
Message-ID: <20250219193007.2336670-1-jmaloy@redhat.com> (raw)

Reconstruct incoming ICMP headers for failed UDP connect and forward back
to local peer.

v2: - Added patch breaking out udp header creation from function
      tap_udp4_send().
    - Updated the ICMP creation by using the new function.
    - Added logics to find correct flow, depending on origin.
    - All done after feedback from David Gibson.
v3: - More changes after feedback from David Gibson.
