I gave this patch a go, both in the bpf-next tree and manually applied to the 5.5.0-rc3 branch I've been working with up to this point. It does allow for allocating more memory, however packet forwarding no longer works. I did not see any complaints from dmesg, but here is an example iperf3 session from a client that worked before. ry@xd2:~$ iperf3 -c 10.1.0.2 Connecting to host 10.1.0.2, port 5201 [ 5] local 10.1.0.1 port 53304 connected to 10.1.0.2 port 5201 [ ID] Interval Transfer Bitrate Retr Cwnd [ 5] 0.00-1.00 sec 5.91 MBytes 49.5 Mbits/sec 2 1.41 KBytes [ 5] 1.00-2.00 sec 0.00 Bytes 0.00 bits/sec 1 1.41 KBytes [ 5] 2.00-3.00 sec 0.00 Bytes 0.00 bits/sec 0 1.41 KBytes [ 5] 3.00-4.00 sec 0.00 Bytes 0.00 bits/sec 1 1.41 KBytes [ 5] 4.00-5.00 sec 0.00 Bytes 0.00 bits/sec 0 1.41 KBytes [ 5] 5.00-6.00 sec 0.00 Bytes 0.00 bits/sec 0 1.41 KBytes [ 5] 6.00-7.00 sec 0.00 Bytes 0.00 bits/sec 1 1.41 KBytes [ 5] 7.00-8.00 sec 0.00 Bytes 0.00 bits/sec 0 1.41 KBytes [ 5] 8.00-9.00 sec 0.00 Bytes 0.00 bits/sec 0 1.41 KBytes ^C[ 5] 10.00-139.77 sec 0.00 Bytes 0.00 bits/sec 4 1.41 KBytes - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-139.77 sec 5.91 MBytes 355 Kbits/sec 9 sender [ 5] 0.00-139.77 sec 0.00 Bytes 0.00 bits/sec receiver iperf3: interrupt - the client has terminated I'll continue to investigate and report back with anything that I find. -- ~ ry
