            Bug ID: 1562
           Summary: dumpcap captures all available network interfaces when
                    specifying any PCI network interface
           Product: DPDK
           Version: 21.11
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: other

Specifying a non-existent PCI network interface results in packet capture on all valid network interfaces on the host.

When specifying a non-existent network interface or any PCI network interface, all valid PCI network interfaces are captured. The reason is in the static void select_interface(const char arg) function, which was intended to match all network interfaces when specified with the '' character. However, the if (strcmp(arg, "")) selects all interfaces. After modification to if (strcmp(arg, "")==0), it works correctly to specify a single network interface.

Thanks for reporting. It is fixed in main branch, but Stephen says it is not worth to backport to older releases. If it is important for you and you want to send a patch for 22.11 and 23.11 branches, it could be accepted.

Hi,

Is this backported to 22.11.1?

Thanks,
Navn Srinivas

No, it required a couple of other patches related to management of network interface list.

Oh, Thank you, Can you point me to those patches?
we require it on top of 22.11.1, I would like to get those patches back ported on top 22.11.1
