Subject: Temporary fix for bug #599.
X-Git-Tag: suricata-1.4rc1~20
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=refs%2Fpull%2F223%2Fhead;p=thirdparty%2Fsuricata.git

Temporary fix for bug #599.

Treat sigs with negated addresses as non ip-only.

This fix exposes bug #608, which results in 2 failed unittest which
have now been disabled by this commit.  Would be reenabled when we
have #608 fix in.
