monit and grsecurity

[Arkadiusz Miskiewicz]

Monit disables some very usefull checkings when /proc/kcore is not available. 
/proc/kcore is not available on:

- 2.4 with grsecurity
+CONFIG_GRKERNSEC_HIDESYM
...
+  3) You have the additional /proc restrictions enabled, which removes
+     /proc/kcore

- 2.6 on some architectures like ARM

        After reviewing the /proc/kcore and kclist issues, I've decided that 
I'm no longer prepared to even _think_ about supporting /proc/kcore on ARM - 
it just gets too ugly, and adds too much code to make it worth the effort, 
the time or the energy to implement a solution to that problem.
        
        /proc/kcore should probably go away, but in the meantime this just 
allows ARM to ignore the issues.

Linus also suggested to remove /proc/kcore in 2.6.

I suggest adding /proc/meminfo parsing (from ie. procps) to check how many ram 
we have instead of stating /proc/kcore before 4.0 release (which I'm willing 
to test btw).

Thanks!
