This conversion is unfortunate in the sense that Unix local domain sockets are relatively lightweight. LocalHost UDP sockets are much heavier weight since they rely on the full UDP stack. If anyone is up for a complete redesign, then using some shared memory and a POSIX message queue would be lightweight again.
This commit also fixes several bugs that were not testable before the inode tree deadlock. I cannot say that the logic is 100% stable but it does not have basic functionality.
Squashed commit of the following:
fs/userfs: Order locking so that access to the shared I/O buffer is also locked.
fs/userfs: Converts to use LocalHost UDP loopback for IPC.

---help---
|
|
Normally, networking initialization occur in the later phase of the
|
|
boot process in the function up_initialize() when it calls the
|
|
driver initialization function, up_netintialize(). This
|
|
initialization occurs after a sufficient about of the OS has been
|
|
initialized so that driver registration can be performed, but
|
|
before the completion of OS initialization and before the first
|
|
application is started.
|
|
|
|
In a few situations, however, you may want to suppress this early
|
|
network driver initialization. As examples:
|
|
|
|
- If you are using SLIP or PPPD, then there will be no network
|
|
driver to be initialized,
|
|
- Certain multi-network configurations where a simple call to
|
|
up_netinitialize() may be insufficient, and
|
|
- Situations where there are other board-level hardware
|
|
dependencies so that the hardware is not in an appropriate
|
|
state for up_netinitialize() to be called.
|
|
|
|
Examples of this latter situation includes such things as network
|
|
drivers that required some setup via an I2C I/O expander, or network
|
|
drivers that depend on USB, SPI, I2C, PCI, serial, or other
|
|
interfaces that may not be ready when up_netiniailize() is normally
|
|
called.
