*Note: Please adhere to [Contributing Guidelines](https://github.com/apache/nuttx/blob/master/CONTRIBUTING.md).* ## Summary Add a `-t` runtime option to `rexecd` to serve each accepted connection inline in the main task, instead of spawning a detached worker thread per connection. By default `rexecd` calls `pthread_create()` for every connection, with a `CONFIG_NETUTILS_REXECD_STACKSIZE` stack allocated from the heap, so that sessions can run concurrently. With `-t`, the thread attributes are skipped and `doit()` is called directly in the accept loop, avoiding the per-connection worker stack. This helps on low-memory targets with limited free heap. The trade-off is that connections are served one at a time. Without `-t`, the existing behaviour is unchanged. ## Impact - New opt-in `-t` flag; usage text updated. - Default behaviour and existing command lines are unaffected. - No new Kconfig options or dependencies; build process unchanged. - Backward compatible. Only trade-off with `-t` is loss of concurrency. ## Testing - `nuttx/tools/checkpatch.sh -f netutils/rexecd/rexecd.c` => all checks pass. - Default mode: `rexecd` + `rexec`, thread-per-connection path works. - Threadless mode: `rexecd -t` + `rexec`, command runs inline, single session works end to end. -- This is an automated message from the Apache Git Service.
