I had a similar reaction as Hugh when I recently updated a kernel config from 4.14 to 4.15. I barely understand the kernel config options in question so I don't really know what is right or wrong. But it seems strange to me that when you turn off CFG80211_CERTIFICATION_ONUS in menuconfig that the options which get hidden are forced on. When options are hidden like this I assume (maybe incorrectly) that they are dependent on the option I just turned off and that the now hidden options will also be off. Kevin

Great to enable that, but not so great to force new stuff on everyone. It doesn't surprise me at all if the patch here is the wrong one, but something needs to be done differently in this configuration. Perhaps you did not try on a system without SYSTEM_DATA_VERIFICATION already enabled - that "select SYSTEM_DATA_VERIFICATION" seems to be taking effect even when CFG80211_REQUIRE_SIGNED_REGDB is not enabled, and pulls in a boatload. I agree that seems strange: perhaps the Kconfig problem is somewhere else entirely. Attached my old 4.14 config, so you can see for yourself - thanks.
