Hi, Daniel,
I am getting "Inconsistent IP pool management (start not found)" on
every Wi-Fi P2P disconnect.
Connman side is master of this connection. Other side is Android that
first connects to connman. And after that disconnect is also issued
from Android side.
Upon disconnect IP pool corresponding to P2P in connman is deleted due to:
__connman_ippool_unref_debug < stop_dhcp_server <
connman_peer_set_state(CONNMAN_PEER_STATE_DISCONNECT)
After that we get
__connman_ippool_deladdr < __connman_ipconfig_deladdr < process_deladdr
from which error print originate.
Not sure how bad is that but it is clearly not consistent with comment
/* In theory this should never happen */
connman_error("Inconsistent IP pool management (start not found)");
Kind regards,
Vasyl

IIRC, the assumption was that we always first get a delete address
before device removal. In this example connman_peer_set_state() is
already destroying the pool. Well, I added the error message to find
bugs in the code. But the code looks quite stable now. So I suggest you
remove the error message and add the above information to the commit
message.
Thanks,
Daniel

Hi,
?
when using
/usr/local/lib/connman/test/set-ipv4-method ethernet_MAC_cable manual <ip>
<netmask> <gateway>,
the IP for eth0 is changed to the given value, but after rebooting, it's using
DHCP again.
Is there an alternate method to manually modify the config file
/var/lib/connman/ethernet_MAC_cable/settings,
for example a command for storing the current configuration?

?

Ok, manually editing
/var/lib/connman/ethernet_MAC_cable/settings
neither is the way to go.
As far as I understand, I would need a .conf file under /var/lib/connman/
to store settings permanently.
This would create a "provisioned service",
but as stated in
https://git.kernel.org/pub/scm/network/connman/connman.git/tree/doc/service-api.txt,
it's not possible to use SetProperty for provisioned services.
Since connman never updated /var/lib/connman/ethernet_MAC_cable/settings,
I also tried to delete the directory /var/lib/connman/ethernet_MAC_cable (after
stopping connman service).
The situation right now is, that eth0 is up, configurable by connmanctl,
but the directory /var/lib/connman/ethernet_MAC_cable is missing
and after reboot, the configuration is dhcp again.
So what would be needed for having a static IP for eth0 persistently?
Under what circumstances does connman create those config files
under /var/lib/connman/ and how can it be forced (if possible)?

FWIW, this looks like a dictionary with two values too me instead of a single
string.

You should not edit the /var/lib/connman/ethernet_MAC_cable/settings by
hand. ConnMan will overwrite them now and then. Though you can write
provisioning configuration file.
See doc/config-format.txt file for more details.
Thanks,
Daniel

Create a /var/lib/connman/myconfig.config file.

Anything below /var/lib/connman/ expect the .config files is
under control of ConnMan. ConnMan monitors the .config file
changes. No need to restart.

forced to what?
