Subject: [package] firewall:
X-Git-Url: http://git.rohieb.name/openwrt.git/commitdiff_plain/5acb7ec58a5220ac99bbc6ca274bc698191fff49?hp=1bd8850ada856207a9c1c5daab54cbbfd793b769

[package] firewall:
	- defer firewall start until the first interface is brought up by hotplug, fixes race conditions on slow devices
	- create a file lock during firewall start and wait for it in hotplug events, prevents race conditions between start and addif
	- start firewall actions in background from hotplug handler since the firewall itself fires further hotplug events which results in a deadlock if not forked off
	- get loaded state direcly from the uci binary since updated value is not recognized by config_get after uci_set_state
	- bump package revision to r2
