I've just been talking to Dan Williams about how to make NetworkManager
play nice with Windows Mobile devices, both in ActiveSync and ICS modes.
We've come up with one big concrete issue.
The networking side of things needs to be handled differently in ICS and
ActiveSync modes. 10-synce.fdi is written to set up the network
interface for synchronization. It should therefore only kick in when the
device is in sync mode. However, it doesn't.
In ICS mode, the network interface needs to be set up differently (it
needs what you get via DHCP, which is usually an address of
192.168.0.102). But as things stand, if you try to use ICS mode on a
system with synce-hal installed, it won't work, because the synce-hal
scripts will keep on kicking in and adding the 'pda' and 'sync'
capabilities and setting the IP address to 169.154.2.2 and so on.
This is because 10-synce.fdi is overbroad in its matching. It just does:
<match key="@info.parent:info.linux.driver" string="rndis_host">
this isn't good enough, because the driver will be rndis_host even when
the device is in ICS mode.
Dan got me to compare some lsusb output in ActiveSync and ICS modes, and
he also found some documentation. His conclusion was:
<dcbw> looks like Class 239, SubClass 1, Protocol 1 identifies sync
devices according to rndis_host.c
<dcbw> but synce *certainly* should update their HAL fdi file to only
match 239/1/1 devices before tagging them with sync - just using
rndis_host isn't sufficient
What Dan's planning to do is have NM handle the device as a regular
network interface if the device is in ICS mode, and handle it specially
so that synchronization still works if it's in ActiveSync mode. But for
this to happen, we need synce-hal to do things properly.
Dan also noticed a typo in hal-synce-rndis line 215:
if config.has_option('rndis', 'statis_local_ip'):
'statis' should be 'static'.
