[PATCH] bluetooth: Remove Bluez 4.x support
by Patrik Flykt
Remove Bluez 4.x support as the 4.x versions have been discontinued
for quite some time already. Bluez 5.x versions have been supported
since ConnMan 1.11 and are actively maintained.

[PATCH] vpn: Add an optional configuration option to the VPN plugin for choosing the device type.
by Hendrik Donner
This allows to use virtual tap devices and removes the hardcoded default to
virtual tun devices.
Signed-off-by: Hendrik Donner <hendrik(a)rennod.org>
---
Only tested with OpenVPN. I have no idea if one of the other VPN plugins
would benefit from tap device support.

[RFC] vpn: Restrict connman-vpnd capabilities
by Patrik Flykt
Have systemd set /home and /run/users read only as VPN certificates can
be stored also in these directories. Protect other directories in the
system by making also them read only. The directory options affect also
all VPN applications started by connman-vpnd.
Restrict capabilities to a subset necessary for normal operations.
---
ProtectSystem=full means the VPN applications cannot write anything to
/usr or /etc. Let's hope this works out for all VPN daemons.
Please test,
Patrik

[RFC] service: Move service to state ready if defaultroute is removed
by Patrik Flykt
When the default route is removed, it is more than likely that the
corresponding service cannot be in state online anymore. Downgrade
the affected service state. This in turn will trigger a new online
check and resolve the state back to online if at all possible.
---
This might fix the issue with dhcp_failure() reported by Naveen Singh.
Please test!

[PATCH] gdhcp: use opened listening socket to send DHCP renew request
by Feng Wang
It fix DHCP ACK lost issue when doing DHCP renewal.
When doing DHCP renew, 2 sockets are opened. One is for
listening DHCP ACK, the other is for transmitting DHCP request
which is closed immediately after transmitting is done. But in
some cases, the socket is closed after the DHCP ACK is received.
The kernel will route the packet to the transmitting socket
because it has a better match result(dst ip/port etc). And the
packet was dropped when the socket was closed.

[PATCH] gdhcp: use opened listening socket to send DHCP renew request
by Feng Wang
DHCP Renew Failure:
When connmand doing DHCP renew, we found out sometimes the DHCP ACK was lost.
But the DHCP ACK packet was received in the IP layer. The tcpdump shows the packet,
but the packet isn't passed to the glib and connmand.
Failure Reason:
The packet was routed to the wrong socket. Connmand created 2 sockets to do the DHCP renew.
One is for listening the received DHCP ACK(dhcp_l3_socket), the other is to transmit the
DHCP request(dhcp_send_kernel_packet). The transmit socket is closed immediately when the
request is transmitted. Normally, the socket is closed before DHCP ACK is received, so the
DHCP ACK is routed to the listening socket. But when adding some debug information in the kernel,
we found in some cases, the socket was closed after DHCP ACK arrived. In this case, the packet
was routed to the transmitting socket, because it has a better match result. But the connmand
only listen on the listening socket, and this packet was dropped when the socket was closed.
Proposed Fix:
Use one socket to listen and transmit similar to NTP implementation. When doing the DHCP renew,
use the listening socket to transmit request. The new code will create a new socket if no socket
opened(current code) in the DHCP release case, else it will use existing socket in the DHCP renew case.
I attached the patch in the next email.

The AddNetwork D-Bus call creates a new network configuration (eg, a
wpa_ssid). It is the responsibility of the thing calling AddNetwork
(eg, connman) to track what network configurations it has already added
and to remove them when they are no longer in use.
Continuously calling AddNetwork without ever removing networks
previously created with AddNetwork would certainly lead to a memory
leak, but that is mis-use of the supplicant's API.
Connman does call RemoveNetwork when the internal network object is
disconnected, but that can happen in any number of cases. I'd suggest
filing a bug with the Connman team to see if they can track it down.

[RFC 1/2] Storage based service retrieval
by MANIEZZO Marco (MM)
Hello,
I'm proposing changes related to the attached discussion, on retrieval of stored services information, in two RFC proposals:
RFC (1): Add a method GetKnownServices to the Manager that has similar behavior of GetServices but the source is not the active services list but the services stored in STORAGEDIR.
RFC (2): Deletion of stored service: as far as I understood, provisioned services (the one with a .config file) cannot be deleted with Remove method of Service, but after testing of the WiFi technology I saw that it is not possible to remove (STORAGEDIR)/service_folder/settings even if there is no .config file, with the Remove method of a Service. This will lead to an increasing storage unless manually file deletion is done. The RFC then is to change the _connman_service_remove function to actually delete folders and files, when possible, meaning I would preserve current conditions to return false in _connman_service_remove and moreover the .config files in (STORAGEDIR) won't be touched.
This email is to start with the RFC (1) modifications and see if my ideas are approved, because I made some assumptions that I hope are not a misunderstanding:
a) currently from Service component, using Storage component it is possible to access only information stored in (STORAGEDIR)/service_folder/settings and not (STORAGEDIR)/files.config. The latter is only accessed by Config component
b) the user can create a .config file in STORAGEDIR containing the information of connection (including passphrase for WiFi) of the services he already knows, so connman can connect (or autoconnect) to them without interaction. If a connection is made to these services with success, then a corresponding folder with a settings file will be created in (STORAGEDIR)/, that will reflects the .config file. Until a connection is done, only the .config file will exists. For services that don't have a .config file, after the user succeeds to connect to them the (STORAGEDIR)/service_folder/settings will be created.
Basing on the above assumption, mainly for (a) which would require further modifications, the GetKnownServices only retrieves the services that have (STORAGEDIR)/service_folder/settings; it will not read the content of the .config files. For our personal usage this is not a limitation because we won't have .config files, moreover the Remove method won't be able to remove them, but I'm open to change if you have suggestions.
Here's my proposal for RFC (1):

[PATCHv3] gdhcp: Don't try to remove timer again
by Saurav Babu
GLib-CRITICAL warning message is obtained in below scenario:
1. service is connected and link local address is obtained.
2. Try to disconnect service.
(connmand:8377): GLib-CRITICAL **: Source ID 289 was not found when
attempting to remove it
(connmand:8377): GLib-CRITICAL **: Source ID 303 was not found when
attempting to remove it
When Link Local IP address is obtained then both dhcp_client->timeout
assigned for DISCOVER_TIMEOUT and ANNOUNCE_INTERVAL are already removed
when discover_timeout() and ipv4ll_announce_timeout() function returns
FALSE but the dhcp_client->timeout is not assigned to 0. Now when
dhcp_release() calls remove_timeouts() function then
dhcp_client->timeout is tried to remove again resulting in GLib-CRITICAL
warning. This patch removes all possible remaing timeouts in
g_dhcp_client_start() and explicitly sets dhcp_client->timeout to 0 in
ipv4ll_announce_timeout() function.
