Automation of testing using mac80211_hwsim and Orbit
We can use testing the robustness and functionality of the Linux wireless stack. Ideally we'd like to see automated tests run weekly to ensure there are no regressions for basic functionality. To test mac80211 and cfg80211 we can use and advance mac80211_hwsim as required without the need to actually use hardware. To test actual device drivers we can work with Orbit to use their existing hardware (or purchase new hardware) and infrastructure to automate routine tests. The idea is we'll have a set of standard tests the project developer will write in coordination with the Linux wireless development community. Each driver will run through the set of tests and we'll be able to determine whether or not each driver passes each individual test. We'll mark in green each passed test and with red each failed test. Ultimately it would be great to merge these efforts as part of the Linux Testing Project.
To get started start testing build the wireless-testing git tree and load the mac80211_hwsim driver. Then read the mac80211_hwsim documentation. Then start doing basic AP, STA testing as you would with two devices present on one system, one acting as an AP and another as a STA.
To start testing at Orbit read Orbit's documentation for developers and register for an account.
This work would involve becoming very familiar with 802.11 wireless technology in general, Linux wireless from a user perspective, and kernel side when enhancements are required. Recommended readings are the Oreilly book on 802.11 Networks.
