From dda5d7f265c382fa1cedd34b6e45e378e1b0c99a Mon Sep 17 00:00:00 2001

Subject: src_vipa: Fix abend in memcpy
References: bsc#1141887 bsc#1142048 bsc#1192860
Customer encountered an abend in memcpy().
get_src_ip_entry() calls dm_hash_val() which itself calls memcpy
to copy a sockaddr structure into local storage, but the specified
length is longer than the length of the sockaddr structure.
The fix is to use the correct length for the respective address family.
