The RFC standard multicast querier interval is 120s. Our querier uses in
interval of 20s for better support of roaming clients, but our robustness
setting of 3 leads to external queriers using the standard interval to be
timeout after only 60s, leading to frequent "querier appeared/disappeared"
messages. Increase robustness so that external queriers with any interval
<180s are supported.
This patch moves the prefix4 subnet route from the local-node veth
device to br-client (while keeping the next node ipv4 address on the
local node device).
This is in preparation to allow routing over the br-client interface
later.
* gluon-core, gluon-client-bridge: introduce new firewall zone: local_client
* gluon-core: put clients in local_client zone, introduce drop-zone,
set dns-rules and zones
* gluon-respondd: allow respondd on mesh
* gluon-status-page-api: allow http input on mesh and client
When a Gluon node is used to connect to an uplink router/DHCP server (for
example in deployments without VPN tunnels), the gw_mode must be set to
server; this should be preserved on upgrades.
Fixes#1196
We now create bat0 and primary0 independently of the lower mesh interfaces,
making the whole setup a lot more robust. In particular:
- we can't accidentially destroy primary0 because of concurrent setup and
teardown runs of different interfaces
- bat0 will always exist, even when no mesh interfaces are up (e.g. no link
on wired mesh)
- interfaces going down and up again will never tear down the whole of
batman-adv
- we can enable and disable bat0 independently of the lower interface
states
