This mechanism had multiple problems: - Missing parameter documentation strings. - Multiple calls to k_thread_name_set() from user mode would leak memory, since the copied string was never freed - k_thread_name_get() returns memory to user mode with no guarantees on whether user mode can actually read it; in the case where the string was in thread resource pool memory (which happens when k_thread_name_set() is called from user mode) it would never be readable. - There was no test case coverage for these functions from user mode. To properly fix this, thread objects now have a buffer region reserved specifically for the thread name. Setting the thread name copies the string into the buffer. Getting the thread name with k_thread_name_get() still returns a pointer, but the system call has been removed. A new API k_thread_name_copy() is introduced to copy the thread name into a destination buffer, and a system call has been provided for that instead. We now have full test case coverge for these APIs in both user and supervisor mode. Some of the code has been cleaned up to place system call handler functions in proximity with their implementations. Signed-off-by: Andrew Boie <andrew.p.boie@intel.com> |

The Zephyr OS is based on a small-footprint kernel designed for use on resource-constrained systems: from simple embedded environmental sensors and LED wearables to sophisticated smart watches and IoT wireless gateways. The Zephyr kernel supports multiple architectures, including ARM Cortex-M, Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V, and a large number of `supported boards`_. .. below included in doc/introduction/introduction.rst .. start_include_here Getting Started *************** Welcome to Zephyr! See the `Introduction to Zephyr`_ for a high-level overview, and the documentation's `Getting Started Guide`_ to start developing. Community Support ***************** Community support is provided via mailing lists and Slack; see the Resources below for details. Resources ********* Here's a quick summary of resources to help you find your way around: * **Help**: `Asking for Help Tips`_ * **Documentation**: http://docs.zephyrproject.org (`Getting Started Guide`_) * **Source Code**: https://github.com/zephyrproject-rtos/zephyr is the main repository; https://elixir.bootlin.com/zephyr/latest/source contains a searchable index * **Releases**: https://zephyrproject.org/developers/#downloads * **Samples and example code**: see `Sample and Demo Code Examples`_ * **Mailing Lists**: users@lists.zephyrproject.org and devel@lists.zephyrproject.org are the main user and developer mailing lists, respectively.
