Title:
[focal, jammy]Enable rdma-sniffer for libpcap
Status in linux package in Ubuntu:
Incomplete
Bug description:
Hi,
The request is to build and configure stock package libpcap with rdma-sniffer
enabled.
We'd like users of rdma devices to be able to sniff on them using stock
tcpdump.
Currently when using default tcpdump It does not list rdma devices.
$ tcpdump -D |grep -i rdma
$
when using locally build tcpdump (with rdma enabled)
$ cd <tcpdump source folder>
$ ./tcpdump -D |grep -i rdma
24.rocep4s0 (RDMA sniffer)
25.rocep7s0f0 (RDMA sniffer)
26.rocep7s0f1 (RDMA sniffer)
27.rocep10s0f0 (RDMA sniffer)
28.rocep10s0f1 (RDMA sniffer)
29.rocep33s0f0 (RDMA sniffer)
30.rocep33s0f1 (RDMA sniffer)
31.rocep36s0f0 (RDMA sniffer)
32.ibp36s0f1 (RDMA sniffer)
Locally build steps:
clone sources:
$ mkdir tcpdumpbuild
$ cd tcpdumpbuild/
$ git clone https://github.com/the-tcpdump-group/tcpdump.git
$ git clone https://github.com/the-tcpdump-group/libpcap.git
install required packages (including rdma packages so libpcap is built with
rdma enabled):
$ apt install flex bison librdmacm-dev librdmacm1 rdma-core rdmacm-utils
configure and build
$ cd libpcap
$ ./autogen.sh
$ ./configure --enable-rdma=yes
$ make
cd ../tcpdump/
./autogen.sh
./configure
$ make
now ./tcpdump -D can show rdma devices.
Thanks !
