Package: hostapd
Version: 1:0.5.7-1
Severity: normal
Tags: patch
When launching hostapd via /etc/network/interfaces using the hostapd
statement in an interface definiton and using bridging with the
madwifi driver of hostapd, ifupdown.sh should add the wireless
interface to the bridge interface.
In case you are not familiar with using hostapd with madwifi, quoting
hostapd.conf:
--8<---
# In case of madwifi driver, an additional configuration parameter, bridge,
# must be used to notify hostapd if the interface is included in a bridge. This
# parameter is not used with Host AP driver.
#bridge=br0
--8<---
Obviously, the whole setup only works, if the wireless interface is
part of the bridge.
In a static configuration where hostapd is launched from
/etc/init.d/hostapd, one can arrange for the bridge to be configured
in /etc/network/interfaces after the wireless interfaces.
In a dynamic setup that launches hostapd via /etc/network/interfaces
and wireless interfaces can be brought up and down any time,
statically configuring the bridge via /etc/network/interfaces is
obviously not possible.
The attached patch fixes this issue.
Removing of the interface from the bridge in post-down is unnecessary,
as the interface is removed automatically when it goes down (which
leads to the situation that it has to be added again each time it is
brought up).
