Public bug reported: 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.
