Subject: host: Properly initialize struct sockaddr_in[6] when parsing strings
X-Git-Tag: 5.1.0~3
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ed0efaef4c13ba9b445520f94153e9261e4acd5e;p=thirdparty%2Fstrongswan.git

host: Properly initialize struct sockaddr_in[6] when parsing strings

Otherwise struct members like sin6_flowinfo or sin6_scope_id might be
set to bogus values.
