The hardware is fairly straightforward on both test boxes, we are using Opt= eron CPUs with igb Ethernet cards and the aforementioned Intel X520 card. Each = of the X520 cards in each box are directly connected together, with the IPsec = link running across them, and plain-text packets are being forwarded from the igb interfaces across the tunnel in both directions. On the Strongswan / IPSec side, the P2 tunnel is established in AES256-GCM = mode with no hashing using the in-kernel AES-NI acceleration. This setup works perfectly as long as async_crypto=3D0, as soon as async_cr= ypto is set to 1 on the FreeBSD 13 system packets start being dropped as they transit the IPSec tunnel. Setting async_crypto back to 0 immediately stops= the packet loss.=20 Reverting to FreeBSD 11 with otherwise the same setup completely "resolves" the issue, but that is obviously not a viable solution. --=20 You are receiving this mail because: You are the assignee for the bug.=
