Subject: tcp: Don't make syn cookies initial setting depend on CONFIG_SYSCTL
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=e994b7c901ded7200b525a707c6da71f2cf6d4bb;p=deliverable%2Flinux.git

tcp: Don't make syn cookies initial setting depend on CONFIG_SYSCTL

That's extremely non-intuitive, noticed by William Allen Simpson.

And let's make the default be on, it's been suggested by a lot of
people so we'll give it a try.
