Hi,
When trying out veb(4), I ran into a situation where TCP sessions across a
veb(4) bridge stalled while the exact same config using bridge(4) worked fine.
After some investigation, it seems that veb(4) adds an FCS to the outgoing
frame, while bridge(4) doesn't. When this causes the outgoing frame to exceed
1514 bytes, the destination doesn't receive it.
I must note that I was using USB NICs, one of them being quite old.
Am I doing something wrong, or is the problem in (one of) the NIC(s)?
The configuration of the veb(4) bridge was as follows (full dmesg below):
openbsd$ ls -l /etc/hostname.*
-rw-r----- 1 root wheel 3 Mar 19 10:08 /etc/hostname.axe0
-rw-r----- 1 root wheel 3 Mar 19 10:08 /etc/hostname.ure0
-rw-r----- 1 root wheel 21 Mar 21 16:16 /etc/hostname.veb0
openbsd$ cat /etc/hostname.axe0
up
openbsd$ cat /etc/hostname.ure0
up
openbsd$ cat /etc/hostname.veb0
add ure0
add axe0
up
The configuration of bridge(4) was exactly the same, I simply renamed
hostname.veb0 to hostname.bridge0 and rebooted.
On the axe(4) side of the bridge was my Windows 10 PC, on the ure(4) side of
the bridge was my home network.
On the Windows 10 PC, I used ICMP echo requests to the default gateway to
diagnose the problem.
Using bridge(4) it went as expected:
* When sending an echo request with a payload of 1473 and DF set, Windows
wouldn't send the packet: "Packet needs to be fragmented but DF set."
* Payload 1472 and DF set: no packet loss
Using veb(4), this happened:
* Payload 1473, DF set: "Packet needs to be fragmented" (expected)
* Payload 1472, 1471, 1470 or 1469 and DF set: 100% packet loss (not expected)
* Payload <=1468 and DF set: no packet loss (expected)
On the bridge, I ran Wireshark on axe0 (where the Windows PC was attached). I
noticed that the echo reply was logged by Wireshark when using bridge(4) as
well as when using veb(4). When using bridge(4) the frame had a size of 1514,
but when using veb(4) the frame had a size of 1518. Inspecting the differences
between the frames with the echo response revealed that veb(4) seemed to
insert the FCS (on the right) while bridge(4) doesn't:
