Subject: [PATCH] Ensure search_servers domain is set on dnssec
|
|
|
|
When dnssec validation is enabled the domain variable used when fetching
|
|
dnssec key or domain were not properly initialized always. It were read
|
|
anyway inside search_servers. Because it is changed only sometime, do
|
|
not use its value on the end of function. domain can be NULL only at
|
|
that point, use that value right away.
|
|
|
|
Include also TCP.
