Subject: s4:libnet Make the libnet_vampire default callbacks non-static
X-Git-Url: http://git.samba.org/?p=kamenim%2Fsamba.git;a=commitdiff_plain;h=1104b41f1e7d794f0bb52b9f8c96d7fe43ca0edc

s4:libnet Make the libnet_vampire default callbacks non-static

These are intended to be called from the NET-API-BECOMEDC torture test
to avoid duplication of code.
