Hello, please review the following fix . In NetworkInterface.c and Inet6AddressImpl.c we have some coding that omits checking for ifa_addr == NULL when iterating on the result of the getifaddrs call. This is similar to what has been fixed in hotspot with
https://bugs.openjdk.java.net/browse/JDK-8208676 The issues are in the bsd/macOS coding. However bsd/macOS also document that ifa_addr can be NULL in special cases (not sure how likely it is to see it "in the wild"). See https://www.freebsd.org/cgi/man.cgi?getifaddrs https://developer.apple.com/library/archive/documentation/System/Conceptual/ManPages_iPhoneOS/man3/getifaddrs.3.html Additionally a small resource leak in NetworkInterface.c is fixed. Bug/webrev : https://bugs.openjdk.java.net/browse/JDK-8216355 http://cr.openjdk.java.net/~mbaesken/webrevs/8216355.1/ Best regards, Matthias
