Subject: samba: add file/interface reload triggers & filter interfaces
X-Git-Tag: v17.01.0-rc1~1715
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=63f6fc5c16996cc47369bb0d6ef28ccd39845e7b;p=openwrt%2Fopenwrt.git

samba: add file/interface reload triggers & filter interfaces

* Only parse interfaces that are up during init_config (as the
  script depends on this to determine the proper IP/subnet range)
* Add reload interface triggers for samba-designated interfaces
* Force full service restart upon config change to ensure Samba
  binds to new interfaces (sending HUP signal doesn't work)
* Rename "interface" variable to "samba_iface" and move into
  global scope

Needed to fix Samba connectivity for clients connecting from a
different LAN subnet (e.g. pseudobridge configurations) due to the
'bind interfaces only' setting.
