[PATCH 2/5] tethering: Use the prefix lenght from ippool instead of hard coded value

We were always using prefix length 24 instead of the correct

value from ippool.

[PATCH 3/5] connection: Use netlink functions to set default gateway
|
||||
Von:
|
||||
Jukka Rissanen <jukka.rissanen@linux.intel.com>
|
||||
Datum:

An:
|
||||
connman@connman.net
|
||||
|
||||
We were using earlier the ioctl() to set the default gateway.
|
||||
In some cases that could fail because the desired interface
|
||||
was not set when calling the ioctl().
|
||||
This happened with tethering with following scenario:
|
||||
* Ethernet cable (uplink connection) is not connected
|
||||
* Wifi tethering is started with address 192.168.1.1
|
||||
* Ethernet cable is connected, uplink address is 192.168.1.0/24
|
||||
* There is now a conflict, ippool resolves that in __connman_ippool_newaddr()
|
||||
and calls tethering_restart() which stops and then starts tethering
|
||||
* Because of the problems when calling the SIOCADDRT (we do not know
|
||||
to what interface the default route was added to), the default route
|
||||
of uplink connection was added to tethering interface (tether) instead
|
||||
of uplink interface (eth0). This caused the default route to disappear
|
||||
when tether interface was taken down.
|
||||
* Solution was to use the netlink interface to set the default gateway
|
||||
as we can unambiguously set the desired default route to be via the
|
||||
uplink interface
|
||||
|
||||
Thanks for Stephan Raue for reporting this issue.
