bridge: Allow setting multicast_fast_leave_option
Setting the multicast_fast_leave option of a bridge allows to control
the forwarding of multicast traffic when an IGMP/MLD leave is received.
In case multicast_leave_option is enabled and a leave is received the
multicast membership will immediately be dropped on the bridge port while
in the other case the multicast membership will time out in the bridge.

host tracking is not supported in the upstream network. In this case the

Revert "add prelocal table to manipulate locally destinated traffic"
Revert commit
3eea8576d48d9b20cc1c6b46f54c7345a39d13aa since it changes the
default behaviour of user ip rules in unexpected ways.
When an ip rule is added without an explicit priority then the kernel will
use the priority value of the 2nd rule, decreased by one.
On an ordinary system, the 2nd rule usually is "from all lookup main" with
priority 32766 which means that user rules are added beginning with priority
32765 in decreasing order.
Since the introduction of the prelocal rule at prio 0 and the subsequent
moving of "from all lookup local" to prio 1, the kernel will insert all user
rules with priority 0, between the prelocal and local lookup rules, leading
to broken routing in many common scenarios.

interface_ip_set_enabled() is usually called two times right after one another,
once to handle config_ip and once to handle proto_ip. As long as
ip->iface->l3_dev.dev is set, the local/source policy rules are updated.
This value is in several cases set on both config_ip and proto_ip, causing the
rules to be added multiple time. The reason is that the kernel does not respect
the NLM_F_* flag for rules. In other words, the rule state has to be managed by
the routing daemon.
Since the local/source policy rules are bound to iface, this commit solves the
problem by adding a flag to interface which stores the current rule state. The
flag follows the enabled-paramter passed to interface_ip_set_enabled(), similar
to route-> and addr->enabled. The flag breaks the alignment of the interface
struct, but based on earlier commits this seems to be ok.

Before this change a vlan/macvlan device could still have link_state enabled if an interface

the netlink link_state event would be dropped for vlan/macvlan devices due to keep_link_state

Test case:
Initial wireless configuration:

option mode sta
option disabled 0
config wifi-iface

After reboot, multicast to unicast feature is configured for interface #3 (wlan0-1) only.

It should be configured for interfaces #1 and #3 only. This patch resolves this problem.

bridge: Allow setting multicast_router option
The multicast_router option of a bridge allows to control the forwarding
behaviour of multicast packets independant of the listener state:
* 0: Only forward if specific listener is present
* 1 (default): Forward if specific listener or a multicast router
was detected (currently only learned via query messages, no MRD
support yet)
* 2: Always forward any multicast traffic on this port
Since MRD is not mandated you might end up with silent multicast routers
(e.g. if your link has more than one multicast router; only one can
become the selected, "noisy" querier). Here you might need a manual
configuration option like the "multicast_router" option.
Other scenarios where this can be useful are for instance:
* Segmentation of IGMP/MLD domains together with ebtables
* Dedicated bridge port for monitoring/debugging purposes

bridge: Fix multicast_to_unicast feature by hairpin+isolate
All IGMP and MLD versions suffer from a specific limitation (from a
snooping switch perspective): Report suppression.
Once a listener hears an IGMPv2/3 or MLDv1 report for the same group
itself participates in then it might (if this listener is an IGMPv3 or
MLDv2 listener) or will (if this is an IGMPv1/2 or MLDv1 listener)
refrain from sending its own report.
Therefore we might currently miss such surpressing listeners as they
won't receive the multicast packet with the mangled, unicasted
destination.
Fixing this by first isolating the STAs and giving the bridge more
control over traffic forwarding. E.g. refraining to forward listener
reports to other STAs.
For broadcast and unicast traffic to an STA on the same AP, the hairpin
feature of the bridge will reflect such traffic back to the AP
interface. However, if the AP interface is actually configured to
isolate STAs, then hairpin is kept disabled.

could fail redialing the connection (segfault or abort) without the

This patch solves it by allowing users to configure an timeout value
