Bug ID: 13198 Summary: tshark fails to pass RPC-over-RDMA frames to RPC subdissector Product: Wireshark Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Severity: Normal Priority: Low Component: TShark Assignee: bugzilla-ad...@wireshark.org Reporter: chuck.le...@oracle.com Created attachment 15101 --> https://bugs.wireshark.org/bugzilla/attachment.cgi?id=15101&action=edit Capture containing frames which should be displayed as NFS Build Information: TShark (Wireshark) 2.3.0 (v2.3.0rc0-1604-g11894f8) Copyright 1998-2016 Gerald Combs <ger...@wireshark.org> and contributors.

Compiled (64-bit) with libpcap, with POSIX capabilities (Linux), with libnl 3, with GLib 2.48.2, with zlib 1.2.8, with SMI 0.4.8, with c-ares 1.12.0, without Lua, with GnuTLS 3.4.16, with Gcrypt 1.6.6, with MIT Kerberos, with GeoIP, without nghttp2, without LZ4, without Snappy. Running on Linux 4.8.10-200.fc24.x86_64, with Intel(R) Core(TM) i7-5557U CPU @ 3.10GHz (with SSE4.2), with 1981 MB of physical memory, with locale en_US.UTF-8, with libpcap version 1.7.4, with GnuTLS 3.4.16, with Gcrypt 1.6.6, with zlib 1.2.8. Built using gcc 6.2.1 20160916 (Red Hat 6.2.1-2). -- With "tshark -V" the RPC-over-RDMA dissector passes the RPC payload to the RPC dissector (and then it passes the payload to the correct RPC program dissector). Without "-V", the RPC-over-RDMA dissector does not pass the payload on for more dissection. A sample wire capture is attached.
