This ensures that no module record/or entry is added to the unloaded_tainted_modules list if it does not carry a taint.

module: Introduce module unload taint tracking

2022-05-12T17:29:41Z

Currently, only the initial module that tainted the kernel is recorded e.g. when an out-of-tree module is loaded. The purpose of this patch is to allow the kernel to maintain a record of each unloaded module that taints the kernel. So, in addition to displaying a list of linked modules (see print_modules()) e.g. in the event of a detected bad page, unloaded modules that carried a taint/or taints are displayed too. A tainted module unload count is maintained. The number of tracked modules is not fixed. This feature is disabled by default. Signed-off-by: Aaron Tomlin Signed-off-by: Luis Chamberlain
