<p>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 RTOS’s (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()).</p>

+
+=======================
+User and Group Identity
+=======================
+
+When ``CONFIG_SCHED_USER_IDENTITY`` is enabled, each task group maintains POSIX
+process credentials. All threads within a task group share the same credentials
+(see :ref:`tasks-vs-threads`).
+
+Credentials
+===========
+
+The full POSIX three-field credential model is stored in ``struct
task_group_s``
+(``include/nuttx/sched.h``):
+
+* ``tg_uid`` / ``tg_gid`` — real user and group IDs.
+* ``tg_euid`` / ``tg_egid`` — effective IDs used for permission checks.
+* ``tg_suid`` / ``tg_sgid`` — saved set-IDs that allow a non-root process to
+ restore a previously held effective ID.
+
+All six fields are zero-initialized at task creation, so the initial task runs
+as root (UID/GID 0) unless explicitly changed.
+
+Inheritance
+===========
+
+When a new task is created, ``group_inherit_identity()`` in
+``sched/group/group_create.c`` copies all six credential fields from the parent
+task group to the child task group.
+
+Privilege Transitions
+=====================
+
+``setuid()`` and ``setgid()``
+-----------------------------
+
+When the effective ID is zero (root):
+
+* ``setuid(uid)`` sets ``tg_uid``, ``tg_euid``, and ``tg_suid`` to ``uid``.
+* ``setgid(gid)`` sets ``tg_gid``, ``tg_egid``, and ``tg_sgid`` to ``gid``.
+
+When the effective ID is non-zero:
+
+* The caller may only set the effective ID to the current real or saved value.
+* Any other value causes the function to return ``-1`` with ``errno`` set to
+ ``EPERM``.
+
+``seteuid()`` and ``setegid()``
+-------------------------------
+
+When the effective ID is zero, any value may be assigned as the new effective
+ID.
+
+When the effective ID is non-zero, the requested value must equal the real or
+the saved ID. Otherwise the function returns ``-1`` with ``errno`` set to
+``EPERM``.
+
+This implements the standard POSIX pattern of temporarily dropping privileges
+with ``seteuid()`` or ``setegid()`` and later restoring them to the saved
value.
+
+Configuration
+=============
+
+``CONFIG_SCHED_USER_IDENTITY``
+ Enables per-task-group credential tracking. Without this option, stub
+ root-only versions of all credential interfaces are provided.
+
+``CONFIG_FS_PERMISSION``
+ Enables filesystem ownership and permission enforcement. Requires
+ ``CONFIG_SCHED_USER_IDENTITY``.

-<h2>Linux Device Nodes<a class="headerlink" href="#linux-device-nodes"
title="Permalink to this heading"></a></h2>
-<p>I used to have good Linux expertise a decade or so ago.
-But my current Linux knowledge is dated and rusty.
-I don’t know anything about udev, SystemD, devtmpfs, sysfs, or any of that.
-So this is my simplified understanding.</p>
-<p>Device files work quite a bit differently in Linux and NuttX.
-A device node in Unix/Linux only really contains the only type of the device
-and its major and minor device numbers, i.e., it just holds data.
-So creating the device node does not install or create the driver;
-it simply writes a tiny file containing some special data.</p>
-<p>Nothing happens until you try to open the device.
-If something in the operating system has not initialized and registered
-a driver for that type and major/minor numbers,
-then you fail to open the device.</p>
-<p>So the device nodes and the device drivers are decoupled in Linux/Unix
-and there is a rendezvous that must occur later for the device node
-to actually refer to the device.</p>
-<blockquote>
-<div><p>“(..) Linux maps the device special file passed in system calls
-(say to mount a file system on a block device) to the device’s
-device driver using the major device number and a number of system
-tables, …The major number is actually the offset into the
-kernel’s device driver table, which tells the kernel what
-kind of device it is (whether it is a hard disk or a serial
-terminal) (..)”</p>
-<p class="attribution">—Source:
-www.linux-tutorial.info/modules.php?name=MContent&pageid=94.</p>
-</div></blockquote>
-<p>Normally, when you create a Linux file system, you also create all of the
-standard device nodes. But most of these do not map to real devices.
-If you try to access most of the devices under <code class="docutils literal
notranslate"><span class="pre">/dev</span></code> in Linux, they will
-fail because the underlying driver that maps to that major/minor number
-has not been initialized.</p>

-<p>Only devices drivers can create device nodes and the existence
-of the device node means that the device has been initialized,
-registered, and is ready for use (with the exception of some
-removable devices that may not actually be ready).</p>
-<p>You cannot create device nodes from applications!</p>
-</div>
-<p>You could argue that this simplification is a deviation from my Unix/Linux
-roadmap and would have to agree that you are right.
-But it is also the kind of enabling simplification that makes a tiny
-Unix-like operating system feasible on these lower end MCUs.</p>
-<p>In Linux standard device drivers are initialized and registered as with
NuttX.
-A (privileged) application can create a device node, but cannot initialize
-or register a device driver directly (as far as I know).
-I believe that if you want to instantiate an uninitialized, unregistered
-device driver you would have to install a kernel module containing
-the driver (which would probably also create the device nodes corresponding
-to the driver).</p>
