Bug ID: 929
Summary: rte_dump_stack() is not safe to call from signal
handler
Product: DPDK
Version: 21.11
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: core
Assignee: dev@dpdk.org
Reporter: stephen@networkplumber.org
Target Milestone: ---
A common scenario is to have a signal handler call rte_dump_stack().
Unfortunately, existing version is not safe in signal handler because it
assumes that malloc pool is not corrupted.

Better alternative is libunwind or libbacktrace
