[Weekly Progress Report GSoC 2026] Automatic Extraction of OpenWrt Firmware Image Metadata

[Mohammed Atif]

Hello everyone, this thread will be used to track the progress of the GSoC 2026 project, [Automatic Extraction of OpenWrt Firmware Image Metadata](https://openwisp.io/docs/dev/developer/gsoc-ideas-2026.html#automatic-extraction-of-openwrt-firmware-image-metadata)

[May 18 - May 22] 

What have you worked on this week?

• Implemented the scope of [#418](https://github.com/openwisp/openwisp-firmware-upgrader/issues/418), tested it and got the desired metadata extraction results
• Replaced the subprocess call of the fwtool with the pure python implementation (also covered under #418 and its PR [#421](https://github.com/openwisp/openwisp-firmware-upgrader/pull/421))
• Implemented the scope of [#412](https://github.com/openwisp/openwisp-firmware-upgrader/issues/412)+[#413](https://github.com/openwisp/openwisp-firmware-upgrader/issues/413) in a combined PR, wrote tests for this implementation
• Manually tested the extraction pipeline in the UI after implementing the async extraction task

What are you going to work on next week?

• Continue polishing #421, and the combined PR mentioned above for #412 & #413, and test them more
• Start mapping out the UI and go over the email discussions again to note down the different safety workflows discussed from the perspective of the user

Is there any blocker?

• No
