This upstream commit fixes the behaviour: commit a221d621bb4af414b974ccc40bba26481337d7cf Author: Bryton Lee <brytonlee01> Date: Thu Feb 12 14:16:04 2015 +0800 prevent the read ahead of /proc/slabinfo in ss Signed-off-by: Bryton Lee <brytonlee01> Fix verification is pretty simple using strace as suggested by Stuart: Here's a test of the faulty version: # strace -eopen ss 2>&1 | grep slabinfo open("/proc/slabinfo", O_RDONLY) = 3 With the patch from comment #3 applied, the above command does not produce any output.
