Bug ID: 1622
Summary: ntnic: using signals and threads
Product: DPDK
Version: 25.03
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: major
Priority: Normal
Component: ethdev
Assignee: dev@dpdk.org
Reporter: stephen@networkplumber.org
Target Milestone: ---
No PMD should be making its own threads and must not use standard signal types.
The ntnic PMD is spawning a thread and trying to trap SIGINT.
This is broken for many reasons:
- application may want to manage SIGINT after rte_eal_init() is called
- there are other shutdown signals beside SIGINT (SIGTERM, SIGQUIT, ...)
- spawning a thread outside of EAL creates resource management issues
