This patch adds support for the new backup port option that can be set
on a bridge port. If the port's carrier goes down all of the traffic
gets redirected to the configured backup port. We add the following new
arguments:
$ ip link set dev brport type bridge_slave backup_port brport2
$ ip link set dev brport type bridge_slave nobackup_port
$ bridge link set dev brport backup_port brport2
$ bridge link set dev brport nobackup_port
The man pages are updated respectively.
Also 2 minor style adjustments:
- add missing space to bridge man page's state argument
- use lower starting case for vlan_tunnel in ip-link man page (to be
consistent with the rest)

In __rtnl_talk_iov() main loop, err is a pointer to memory in dynamically
allocated 'buf' that is used to store netlink messages. If netlink message
is an error message, buf is deallocated before returning with error code.
However, on return err->error code is checked one more time to generate
return value, after memory which err points to has already been
freed. Save error code in temporary variable and use the variable to
generate return value.

This traffic scheduler allows traffic classes states (transmission
allowed/not allowed, in the simplest case) to be scheduled, according
to a pre-generated time sequence. This is the basis of the IEEE
802.1Qbv specification.
Example configuration:
tc qdisc replace dev enp3s0 parent root handle 100 taprio \
num_tc 3 \
map 2 2 1 0 2 2 2 2 2 2 2 2 2 2 2 2 \
queues 1@0 1@1 2@2 \
base-time 1528743495910289987 \
sched-entry S 01 300000 \
sched-entry S 02 300000 \
sched-entry S 04 300000 \
clockid CLOCK_TAI
The configuration format is similar to mqprio. The main difference is
the presence of a schedule, built by multiple "sched-entry"
definitions, each entry has the following format:
sched-entry <CMD> <GATE MASK> <INTERVAL>
The only supported <CMD> is "S", which means "SetGateStates",
following the IEEE 802.1Qbv-2015 definition (Table 8-6). <GATE MASK>
is a bitmask where each bit is a associated with a traffic class, so
bit 0 (the least significant bit) being "on" means that traffic class
0 is "active" for that schedule entry. <INTERVAL> is a time duration
in nanoseconds that specifies for how long that state defined by <CMD>
and <GATE MASK> should be held before moving to the next entry.
This schedule is circular, that is, after the last entry is executed
it starts from the first one, indefinitely.
The other parameters can be defined as follows:
- base-time: specifies the instant when the schedule starts, if
'base-time' is a time in the past, the schedule will start at
base-time + (N * cycle-time)
where N is the smallest integer so the resulting time is greater
than "now", and "cycle-time" is the sum of all the intervals of the
entries in the schedule;
- clockid: specifies the reference clock to be used;
The parameters should be similar to what the IEEE 802.1Q family of
specification defines.

iproute2 currently uses ifinfomsg as the header for all dumps using the
wilddump headers. This is wrong as each message type actually has its own
header type. While the kernel has traditionally let it go as it for the
most part only uses the family entry, the use of kernel side filters is
increasing to alter what is returned on a request. The kernel side filters
really need to use the proper header type.
To that end, fix iproute2 to use the proper header struct for the GET type.

Take into account the configured preferred_family if neither saddr or
daddr are provided since otherwise vxlan kernel module will use IPv4 as
default remote inet family neglecting the one provided by userspace.
This behaviour was originally in commit 97d564b90c ("vxlan: use
preferred address family when neither group or remote is specified").
The issue can be triggered with the following reproducer:
$ip -6 link add vxlan1 type vxlan id 42 dev enp0s2 \
proxy nolearning l2miss l3miss
$bridge fdb add 46:47:1f:a7:1c:25 dev vxlan1 dst 2000::2

addr->flags to ADDRTYPE_INET_UNSPEC if family is AF_INET/AF_INET6, which
makes is_addrtype_inet() checking passed and assigns incorrect address
to kernel. The ip link cmd will return error like:
]# ip link add ipip1 type ipip local any remote 1.1.1.1
RTNETLINK answers: Numerical result out of range
