When the secondary process testpmd application running any fwd_engine
and after that primary has exited will cause a crash.
This patch forces secondary process forwarding lcores
in fwd_engine to stop before the primary process exits.

Windows doesn't support secondary processes, not sure how you tested this.
When Windows supports secondary processes it should the existing EAL API's,
not fixing every service.

Yeah, I have tested on Linux only, the code is under the macro

NAK
As you said, you did not test it on Windows, yet you added #ifdef
for Windows support. Since Windows doesn't support secondary
processes (yet) how could you.
Adding Windows here has to wait until it can be tested.

I have tested only on Linux, all the codes are under #ifndef i.e., if

Can you please double check the code?
I have used the following macro everywhere which means the code is only
targeted to Linux.
#ifndef RTE_EXEC_ENV_WINDOWS
I will add a newer version to if you agree to add additional comments to
further clarify that the solution is only targeted for Linux.

Can you please check if my understanding is correct that #ifndef
RTE_EXEC_ENV_WINDOWS means only Linux based systems ?
I have added all the codes under this macro :)

Ok, the Windows #ifdef was confusing me then looked more closely.
This patch is adding a set of rings so that primary and secondary
can communicate, the adding one command.
The idea is good, but there is a better way to handle this.
There already exists a way for primary and secondary to communicate
through the mp service. This is used for hotplug and pdump and probably
other things as well.
The communication can be either way, for example I proposed patches
to pdump so that primary can tell secondary to participate.
https://patchwork.dpdk.org/project/dpdk/patch/20250814165307.12786-7-stephen@networkplumber.org/
This of testpmd can be done in similar way.
The handler in secondary should be able to act same as
when SIGINT is received. Set the flag f_exit which will cause the main
loop to exit.
This can then happen immediately, and the proc monitor alarm function
is only then needed to handle when primary process crashes.
