px4_shutdown_request() was called from the power button IRQ callback, which
invoked a work queue callback. But on NuttX, the work queue uses a
semaphore, and thus it cannot be called from IRQ context.
This patch switches to publishing an uORB msg instead, which is handled in
the commander main thread.
To increase failure resistance, we could subscribe to the same topic in
another module for redundancy, in case commander runs wild.
The message handling was not obeying action focused messages and high-rate messages properly before. With this change update rates track the desired rates closely. Critical high-rate messages such as ADS-B are queued additionally to guarantee that all received packets are being correctly forwarded.
- change memory allocation from stack to a malloc'd buffer. This avoids
increasing the stack size. And since FTP is rarely used, the buffers
are only allocated upon use and freed after a time of 2s inactivity.
- adds PX4_ROOTFSDIR as root directory prefix. This does not change
anything on NuttX, but in SITL it will avoid enumerating the whole
disk tree when using QGC (which enumerates all files recursively).
The provided argument payload->offset is in range [0, num_file_entries-1],
but seekdir might use a completely different range. It is not defined
by the API spec. It is only useful in conjunction with telldir().
This can happen for example when a param type is changed from int32 to
float. The type check will then fail if the param is stored and the param
import will be aborted.
Now we just skip the entry and continue loading the rest.
