Bug ID: 1194
Summary: l3fwd-cat: calling unsafe functions from signal
handler
Product: DPDK
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: examples
Assignee: dev@dpdk.org
Reporter: step...@networkplumber.org
Target Milestone: ---
The handling of SIGINT and SIGTERM in the l2fwd-cat example is unsafe and
non-portable. The signal handler could be called by any thread at any time.
The current method (copy/paste from testpmd?) is to call cat_exit() in the
signal handler. This may race with other threads and cause problems.
The better solution is to set a flag in signal handler and then do the shutdown
aft er the main loop exits.
