Description

There is certain suspicion that if two (and more) independent DPDK Suricata processes with different file prefixes run in parallel, they somehow can affect each other and prevent from shutting down.
There were multiple Suricata processes to make sure Suricata workers ran on the correct NUMA nodes with their respective NICs (placed on different NUMA nodes).

Error message:

Error: suricata: stacktrace:sig 6:gsignal+0x0000010f;abort+0x00000127;__assert_fail_base.cold.0+0x0000000f;__assert_fail+0x00000046;TmThreadClearThreadsFamily+0x00000217;PostRunDeinit+0x000000eb;SuricataMain+0x00002bd2;__libc_start_main+0x000000e5;_start+0x0000002e [SignalHandlerUnexpected:suricata.c:321]

  • Status changed from Assigned to Rejected

Evaluated with multiple DPDK virtual devices (net_null) in the config:

dpdk:
  eal-params:
    proc-type: primary
    file-prefix: second-proc
      # no-huge:
    vdev: ["net_null0", "net_null1", "net_null2", "net_null3"]

No segfault observed.
