The 'created' flag values were incorrectly inverted in file_mq_vopen(): 1. When opening an existing message queue (inode_find succeeds): - Before: incorrectly set *created = 1 (indicating new creation) - After: correctly set *created = 0 (indicating existing queue) 2. When creating a new message queue (inode_find fails): - Before: incorrectly set *created = 0 (indicating existing queue) - After: correctly set *created = 1 (indicating new creation) This bug could lead to incorrect resource management and cleanup behavior in the calling function nxmq_vopen() when file_allocate() returns an error, as it relies on the 'created' flag to determine whether the message queue was newly created and needs to be cleaned up. Impact: - Resource leak when opening existing queues that should not be released - Missing cleanup when creating new queues that should be released on error Signed-off-by: dongjiuzhu1 <dongjiuzhu1@xiaomi.com>
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.
