Binary image publication by firmware
Multiple binary images stored in the firmware of an electronic device are written to the device's configuration tables during booting of the device, where one of the binary images is a manager binary. During booting, the manager binary is saved to the file system of the operating system such that it automatically executes upon completion of booting. The manager binary then deploys the other binary images.
1. A method for publishing multiple binary images from firmware in an electronic device to an operating system in the electronic device, the method comprising:
during booting of the electronic device, the steps of:
installing a first binary image, which is stored in the firmware, into a configuration table in the electronic device;
installing a second binary image, which is stored in the firmware, into the configuration table; and
saving a copy of the first binary image in a file system of the operating system; and
after the operating system has started loading, the step of executing the copy of the first binary image to deploy the secondary binary image.
2. The method of claim 1 , wherein the first binary image deploys the second binary image by:
copying the second binary image to the file system; and
launching the second binary image.
3. The method of claim 2 , wherein the first binary image launches the second binary image as a child process of the first binary image.
4. The method of claim 1 , wherein the first binary image deploys the second binary image by launching the second binary image from the configuration table.
5. The method of claim 4 , wherein the first binary image launches the second binary image as a child process of the first binary image.
6. The method of claim 1 , wherein the configuration table is in firmware.
7. The method of claim 1 , wherein the configuration table is on a disk.
8. The method of claim 1 , wherein the deployed second binary image runs until the electronic device is switched off or rebooted.
9. The method of claim 1 comprising, during the booting of the electronic device, installing one or more further binary images, which are stored in the firmware, into the configuration table.
10. The method of claim 1 , wherein the first binary image allocates memory for execution, copies the second binary image into the allocated memory, and executes the second binary image.
11. The method of claim 10 , wherein the first binary image executes the second binary image by requesting the operating system to start the second binary image as a process.
12. The method of claim 1 , wherein the second binary image has a Data memory attribute in the configuration table.
13. The method of claim 1 comprising, when the second binary image is deployed, the second binary image initiates a network connection from the electronic device to a server.
14. The method of claim 13 , wherein the server uses one or more remote procedure calls to:
load a third binary image from the server to the electronic device; and
launch the third binary image.
15. The method of claim 1 , wherein the second binary image is a script.
16. The method of claim 1 , wherein the second binary image comprises one or more registry entries.
17. The method of claim 1 , wherein the second binary image is configuration data.
18. The method of claim 1 , wherein the first binary image executed while the operating system is loading, by:
saving the first binary image to a file;
loading the first binary image into memory; and
executing the first binary image as a process.
19. An electronic device that publishes multiple binary images, the electronic device comprising:
a processor;
an operating system; and
firmware storing computer readable instructions, which, when executed by the processor cause the electronic device, during booting of the electronic device, to:
install a first binary image, which is stored in the firmware, into a configuration table in the electronic device;
install a second binary image, which is stored in the firmware, into the configuration table; and
save a copy of the first binary image in a file system of the operating system;
and, after the operating system has started loading, execute the copy of the first binary image to deploy the secondary binary image.
20. The electronic device of claim 19 , wherein the first binary image deploys the second binary image by launching the second binary image from the configuration table.
