The sim host usrsock backend only accepted INET/NETLINK domains and
translated socket addresses through plain struct sockaddr. That prevents
simulated applications from using POSIX AF_LOCAL sockets through the
standard socket API when CONFIG_NET_USRSOCK is used.
Add AF_LOCAL address conversion for struct sockaddr_un, allow PF_LOCAL
sockets through usrsock, handle NuttX socket type flags, and poll host
descriptors from the sim usrsock work item so nonblocking
connect/read/write readiness is reported back to NuttX. Use
sockaddr_storage for native address translation so larger address
structures are not truncated.
Testing:
- Host: Ubuntu 22.04 x86_64.
- Board/config: sim:nsh with CONFIG_NET_USRSOCK=y and
CONFIG_EXAMPLES_HELLO=y.
- make clean && make -j16.
- Ran a temporary hello example that connected to host AF_UNIX
SOCK_STREAM and SOCK_SEQPACKET sockets through NuttX socket(),
connect(), write(), and read(). Both received pong and printed
"AF_LOCAL usrsock test passed".

Apache NuttX is a real-time operating system (RTOS) with an emphasis on standards compliance and small footprint. Scalable from 8-bit to 64-bit microcontroller environments, the primary governing standards in NuttX are POSIX and ANSI standards. Additional standard APIs from Unix and other common RTOSs (such as VxWorks) are adopted for functionality not available under these standards, or for functionality that is not appropriate for deeply-embedded environments (such as fork()).
For brevity, many parts of the documentation will refer to Apache NuttX as simply NuttX.
Getting Started
First time on NuttX? Read the Getting Started guide! If you don't have a board available, NuttX has its own simulator that you can run on terminal.
Documentation
You can find the current NuttX documentation on the Documentation Page.
Alternatively, you can build the documentation yourself by following the Documentation Build Instructions.
The old NuttX documentation is still available in the Apache wiki.
Supported Boards
NuttX supports a wide variety of platforms. See the full list on the Supported Platforms page.
Contributing
If you wish to contribute to the NuttX project, read the Contributing guidelines for information on Git usage, coding standard, workflow and the NuttX principles.
