Bug ID: 1698
Summary: rte_eth_rx_burst causes segmentation fault when
encountered in a Secondary process
Product: DPDK
Version: 23.11
Hardware: x86
OS: Linux
Status: UNCONFIRMED
Severity: critical
Priority: Normal
Component: examples
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---

Created attachment 311

This is the screenshot of the log that appears when the secondary process tries to execute tx_burst

I took a copy of the simple_mp main program from multi_process within the DPDK examples and modified it by adding bonding and allowing it to send dummy packets.

Two bonds are created, both are under the Active backup mode. This is done by the primary process.

Once the bonds are created, configured and started, the transmisssion of dummy packets starts. When tx_burst is run for the primary process, the transmission of packets occur without any issue.

However, when the tx_burst is encountered during the Secondary process with the primary process running in another terminal, a segmentation error occurs.

DPDK Version : 23.11
