why is nf_conntrack_htable_size exported?
Folks, Can someone tell me why nf_conntrack_htable_size is both an exported symbol, and available in sysfs to be changed? Doing so will surely cause the system to fall over immediately since this is value is used within the hashing code in conntrack. It is /supposed/ to only be changed under a lock, or at init t... 2 Feb 2010 22:05
