[dpdk-dev] Tcpdump

Hi, I have a DPDK application that binds to an interface and processes packets. For debugging purposes I want to run tcpdump on this interface. IYO, what is my best option with hurting the performance of the application too much? TIA, Dror

[dpdk-dev] pcap: memory leak in eth_pcap_rx_jumbo

Hi, It seems there is a memory leak in eth_pcap_rx_jumbo() in case rte_pktmbuf_alloc() fails on any segment that is not the initial segment. If someone can confirm it, I'll patch it. TIA, Dror

[dpdk-dev] [PATCH] pcap: fix captured frame length

The actual captured length is header.caplen, whereas header.len is the original length on the wire. Signed-off-by: Dror Birkman --- Without this fix, if the captured length is smaller than the original length on the wire, mbuf will contain incorrect data. drivers/net/pcap/rte_eth_pcap.c

[dpdk-dev] PCAP memory leak in freeing jumbo frames

Hi, I have a huge memory leak when I release mbufs allocated by eth_pcap_rx_jumbo(). I use rte_mempool_put_bulk() to release the mbufs. To my horror I found out it puts back to the mempool only the head mbuf and not its segments! I know rte_pktmbuf_free() frees the mbuf and all it segments, but
