CONFIG_GRKERNSEC_HARDENED_WORKSTATION selects GRKERNSEC_PROC_USERGROUP. CONFIG_GRKERNSEC_PROC_USERGROUP depends on (among other things) !GRKERNSEC_PROC_USER. Reproducible: Always Steps to Reproduce: 1. Select CONFIG_GRKERNSEC_HARDENED_WORKSTATION 2. Select GRKERNSEC_PROC_USER 3. Compile Actual Results: You get a warning about unsatisfied dependencies. This bug does not occur under CONFIG_GRKERNSEC_CUSTOM Kernel compiles, the GID you selected is assigned to /proc entries, but has no permission (mode 500). Manually deselecting the conflicting option allows the kernel to operate correctly. Expected Results: You are prevented from selecting conflicting options.

Sorry, slowly getting around to this. I am aware of the issue.
This is actually an upstream problem, since it happens even without the Gentoo predefined CONFIG_GRKERNSEC_HARDENED_{SERVER,WORKSTATION,VIRTUALIZATION}. It has to do with a (potentially) circular dependency between GRKERNSEC_PROC_USER and GRKERNSEC_PROC_USERGROUP. These are mutally exclusive and currently that exclusivity is expressed as: config GRKERNSEC_PROC_USER depends on GRKERNSEC_PROC config GRKERNSEC_PROC_USERGROUP depends on GRKERNSEC_PROC && !GRKERNSEC_PROC_USER You can't do this: config GRKERNSEC_PROC_USER depends on GRKERNSEC_PROC && !GRKERNSEC_PROC_USERGROUP config GRKERNSEC_PROC_USERGROUP depends on GRKERNSEC_PROC && !GRKERNSEC_PROC_USER because that leads to grsecurity/Kconfig:416:error: recursive dependency detected! grsecurity/Kconfig:416: symbol GRKERNSEC_PROC_USER depends on GRKERNSEC_PROC_USERGROUP grsecurity/Kconfig:424: symbol GRKERNSEC_PROC_USERGROUP depends on GRKERNSEC_PROC_USER The solution I would propose is to try config GRKERNSEC_PROC_USER depends on GRKERNSEC_PROC && !GRKERNSEC_PROC_USERGROUP config GRKERNSEC_PROC_USERGROUP depends on GRKERNSEC_PROC although this may lead to other problems
I've added the above fix to hardened-sources-2.6.32-r54 hardened-sources-2.6.39-r4 @Dillon, can you please test. Its working for me.

Okay nearly 1 month no response from reporter. I'll give it 1 more week. At least for the Gentoo predefined grsec/pax profiles, I am no longer hitting this problem. Anyone still having problems with this?
