Subject: Re: [PATCH 2/2] mm: restrict access to /proc/meminfo
Date: Fri, 30 Sep 2011 13:15:14 -0700 [thread overview]
Message-ID: <1317413714.16137.666.camel@nimitz> (raw)

I stuck a printk in there. It's not exactly called 100x a second, but
there were 5 distinct users just for me to boot and ssh in:
[ 3.130408] meminfo read called by: 'udevd' 1
[ 3.326649] meminfo read called by: 'dhclient-script' 2
[ 4.624943] meminfo read called by: 'klogd' 3
[ 8.008019] meminfo read called by: 'dhclient-script' 4
[ 8.083091] meminfo read called by: 'ps' 5
[ 48.171038] meminfo read called by: 'bash' 6
Granted, those were likely privileged. But, that's a good list of
processes that I would rather not see break.
