From 8eea4e74475804285507c077bec87d40be87ff06 Mon Sep 17 00:00:00 2001 From: Jason Gunthorpe Date: Thu, 27 Feb 2025 20:26:32 -0400 Subject: taint: Add TAINT_FWCTL Requesting a fwctl scope of access that includes mutating device debug data will cause the kernel to be tainted. Changing the device operation through things in the debug scope may cause the device to malfunction in undefined ways. This should be reflected in the TAINT flags to help any debuggers understand that something has been done.
