When recompiling sys-apps/keyutils today I saw a warning for KEYS_DEBUG_PROC_KEYS not being set in my kernel (gentoo-sources-4.0.5), and quickly discovered this kernel option no longer exists. The check for KEYS_DEBUG_PROC_KEYS either needs to be removed or updated. Reproducible: Always
I did a quick look to see what replaced it in 4.0, I didn't see it. That said, there are plenty of references to /proc/keys in the source (what is enabled with the KEYS_DEBUG_PROC_KEYS option), so I'm not sure if another option toggles it, or if it is now there by default. Anthony, since I'm not running 4.0, can you confirm if that directory exists when you are running the 4.0 kernel?
I happened to have another system here still running "3.18.11-gentoo" with CONFIG_KEYS_DEBUG_PROC_KEYS enabled. After comparing it against the "4.0.5-gentoo" kernel without that option, it appears as though both the contents of /proc/keys (which is a file, rather than a folder on both of these kernel versions) remains unchanged. Because of this I believe this is now included by default when CONIFG_KEYS is enabled.
v4.0 contained this commit: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=dabd39cc2fb1b0e97313ebbe7309ea8e05b7cfb5 the result of which is that keyutils should check for CONFIG_KEYS=y instead. v4.6 removed KEYS_DEBUG_PROC_KEYS: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=50d35015ff0c00a464e35b109231145d2beec1bd
