[PATCH] consmetics: remove redundant returns at the end of functions that return void
by Vasyl Vavrychuk
Another purpose of this change is making coded to have a same style.
Previous at some functions there was redundant returns and at some no.
If this returns will be in the end of all void functions it will produce
a lot of noise while reading code.

[PATCH v2] plugins: ethernet: get rid of truncate warning

The buffer will never be truncated in reality, but it is the only

Increase group buffer size to not make snprintf nervous about truncating
something.

RE: [PATCH] ipconfig: Incase of Manual IP Configuration, saving Gateway information during network switch
by Rahul Jain
Dear Daniel,
Please find my inputs for your question:-
[Q]Does the initial network have a proper configuration, that is it contains a valid gateway? If so why is it missing when we reach __connman_ipfconfig_save()? Do we call __connman_ipconfig_save() too late?
[A] Scenario:
1. User configured manual IP configuration in wired network with valid details (IP, Gateway, DNS etc)
>> Yes, wired network has proper configuration and connection was successful.
2. Now, user switches from wired to wireless and wireless connection successful.
>> As during wired network disconnection, __connman_connection_gateway_remove() will be called with type 3 (IPv4 + IPv6), where do_ipv4 = do_ipv6 = true; -> g_hash_table_remove(gateway_hash, service); -> remove_gateway() will make gateway null.
Immediately, when service_save()->__connman_ipconfig_save() is called for wired service,at that time, as gateway is null, so valid gateway which was stored already inside /var/lib/connman will be deleted.
As per your question, yes __connman_ipconfig_save is being called after __connman_connection_gateway_remove().
3. Now, user switches from wireless to wired.
>> As stored profile inside /var/lib/connman doesn't have gateway, so wired connection will fail.
Please let us know your opinion.
Thanks

The theory is that the application/user shouldn't worry about scanning.
Even ConnMan shouldn't worry about this. Unfortunately, wpa_supplicant
doesn't do the full job. That's why ConnMan's wpa_supplicant plugin is
so complex (a mess).
Obviously, there are scenarios where you want to tell ConnMan do a scan
now. But you should not constantly tell ConnMan to do a scan. I am sure
this will have some nasty side effects.
Alternatively, you could give iwd a try. Though the current plugin is
only supported the very basic stuff. Needs some more work.
Thanks,
Daniel

This seems to be a repetition of the emails subject. I usually send my
changes out with 'git format-patch' and 'git send-email'.
Anyway, try to trip the subject a bit. Just mention what you change.
Maybe something like 'Save gateway information'

The g_key_file_remove_key() has been added by Craig: 60facabb03a9
("ipconfig: Remove IPv4.gateway key in settings if gateway is not
configured").
I am not sure if I am really understand the problem you want to fix. The
code you are deleting seems quite reasonable. If gateway is valid
(!NULL) save it, otherwise remove it. (The code above these lines should
probably do the same but that's a different story).
Does the initial network have a proper configuration, that is it
contains a valid gateway? If so why is it missing when we reach
__connman_ipfconfig_save()? Do we call __connman_ipconfig_save() too late?
Thanks,
Daniel

[PATCH] ipconfig: Incase of Manual IP Configuration, saving Gateway information during network switch
by Rahul Jain
Subject: [PATCH] ipconfig: Incase of Manual IP Configuration, saving Gateway
information during network switch
[Problem] If user use manual IP configuration while connect with network(suppose wired).
Then during network switch (suppose from wired to wireless), gateway will not be saved into
/var/lib/connman respective profile settings.
So when user come back to earlier network(suppose wired again),
then connection will fail as connman does not have gateway(wrong gateway as 0.0.0.0) to connect.
[Solution] When device switch from wired to wireless network, gateway information was missed
to be saved into /var/lib/connman respective profile. So during Network switch
service_save()->__connman_ipconfig_save() will not remove "IPV4.gateway" key
from respective profile settings file.

[PATCH] service: do not reply twice to Connect
by Benoît Monin
Calling Connect an a service sometime triggers the following error message in
the log:
dbus-daemon[591]: [system] Rejected send message, 0 matched rules;
type="method_return", sender=":1.139" (uid=0 pid=27373
comm="/usr/sbin/connmand -n -d ") interface="(unset)" member="(unset)" error
name="(unset)" requested_reply="0" destination=":1.141" (uid=0 pid=27384
comm="/usr/bin/connmanctl ")
This is caused by connmand replying twice to the Connect method. It can be
reproduced by calling connect on a manually configured ethernet service while
checking the dbus exchange with dbus-monitor. The dbus daemon rejects the
second reply since there is no corresponding method call.
Fix this by exiting connect_service before sending another reply if the
pending reply has already been sent.
