What version of wireshark are you using?
wireshark-3.6.2-1.fc35.x86_64
Wireshark 3.7.0 (v3.7.0rc0-1686-g64dfed53330f)
Works fine for me with 3.6.2-2 on ubuntu and also a recent wireshark
master version.
I just fixed a minor problem with fragmented iwrap_ddp_rdma_send
messages in
frames 91-96. Which seem to happen because ksmbd.ko negotiated a
preferred send size of 8192,
which is accepted by the cifs.ko. Windows only uses 1364, which means
each send operation fits into
a single ethernet frame...
That was not an accident. :)
There's a talk somewhere in which I mentioned how we tried to optimize
the smbdirect fragment size and always landed back on 1364. However,
this is only an implementation choice, the protocol supports a wide
range. So it's appropriate for wireshark to be accommodating.
See https://gitlab.com/wireshark/wireshark/-/merge_requests/7025
I get a blank frame when I view both changes on this link. Do I need
a gitlab account??
Tom.
