Mark Foster created an issue: https://gitlab.rtems.org/rtems/pkg/rtems-lwip/-/issues/8



The lwIP network stack, compatible with [NASA Core Flight Software (cFS)](https://github.com/nasa/cFS), does not support either gethostid() and gethostname() calls. If the [cFS Operating System Abstraction Layer (OSAL)](https://github.com/nasa/osal/) networking module is included then the build will fail to link the module with undefined reference to gethostname and gethostid errors.

Creating this RTEMS Issue per request from Joel Sherrill in original NASA Github Issue with mitigation: [gethostid() and gethostname() not supported by lwIP network #1513](https://github.com/nasa/osal/issues/1513)
