Subject: [Bug 929] rte_dump_stack() is not safe to call from signal handler
Date: Thu, 27 Jan 2022 20:47:39 +0000 [thread overview]
Message-ID: <bug-929-3@http.bugs.dpdk.org/> (raw)
https://bugs.dpdk.org/show_bug.cgi?id=929
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
