[SOLVED] keyctl adds a key, but reading = Permission denied

$ keyctl add user "testing" "somedata" @u
653010022
$ keyctl read 653010022
keyctl_read_alloc: Permission denied

I was chasing a problem in some software that used kernel keys, and ultimately I can reproduce the root issue from the command line like this. I've tested this on LOADS of linux machines, and none of them do this except mine.

I have no idea what could possibly warrant this. Other than CONFIG_KEYS, i have no clue what else would even be relevant.

Kernel: 4.9.34
CONFIG_KEYS=y

Any ideas?

I really have no actual clue, but it seems to me you may need to add your user to some group?

it works on another machine of mine with simply:
wheel users portage <user_name>

This user has that and more.

I'm wondering if this might be systemd related, per https://github.com/systemd/systemd/pull/6286

I tried -9999 systemd and that didn't fix the issue for me either btw. =/

Just tried openrc, works fine... it's definitely that bug. I guess you can call this [SOLVED] even though it's still broken.
