Ido Schimmel 0788678991 nexthop: Always print nexthop flags
Currently, the nexthop flags are only printed when the nexthop has a
nexthop device. The offload / trap indication is therefore not printed
for nexthop groups.

Instead, always print the nexthop flags, regardless if the nexthop has a
nexthop device or not.

Ido Schimmel 3de35f41be ip route: Print "trap" nexthop indication
The kernel can now signal that a nexthop is trapping packets instead of
forwarding them. Print the flag to help users understand the offload
state of each nexthop.

Petr Machata 66a2d71487 lib: parse_mapping: Recognize a keyword "all"
The DCB tool will have to provide an interface to a number of fixed-size
arrays. Unlike the egress- and ingress-qos-map, it makes good sense to have
an interface to set all members to the same value. For example to set
strict priority on all TCs besides select few, or to reset allocated
bandwidth to all zeroes, again besides several explicitly-given ones.

To support this usage, extend the parse_mapping() with a boolean that
determines whether this special use is supported. If "all" is given and
recognized, mapping_cb is called with the key of -1.

Have iplink_vlan pass false for allow_all.

Petr Machata 28e663ee65 lib: Extract from iplink_vlan a helper to parse key:value arrays
VLAN netdevices have two similar attributes: ingress-qos-map and
egress-qos-map. These attributes can be configured with a series of
802.1-priority-to-skb-priority (and vice versa) mappings. A reusable helper
along those lines will be handy for configuration of various
priority-to-tc, tc-to-algorithm, and other arrays in DCB.

Therefore extract the logic to a function parse_mapping(), move to utils.c,
and dispatch to utils.c from iplink_vlan.c. That necessitates extraction of
a VLAN-specific parse_qos_mapping(). Do that, and propagate addattr_l()
return value up, unlike the original.

Petr Machata 82604d2852 lib: Add parse_one_of(), parse_on_off()
Take from the macsec code parse_one_of() and adapt so that it passes the
primary result as the main return value, and error result through a
pointer. That is the simplest way to make the code reusable across data
types without introducing extra magic.

Also from macsec take the specialization of parse_one_of() for parsing
specifically the strings "off" and "on".

Convert the macsec code to the new helpers.

Jan Engelhardt 0ca1312c20 ip: add error reporting when RTM_GETNSID failed
`ip addr` when run under qemu-user-riscv64, fails. This likely is due
to qemu-5.1 not doing translation of RTM_GETNSID calls. Aborting ip
completely is not helpful for the user however. This patch reworks
the error handling.

Jakub Kicinski b8663da049 ip: promote missed packets to the -s row
missed_packet_errors are much more commonly reported:

linux$ git grep -c '[.>]rx_missed_errors ' -- drivers/ | wc -l
64
linux$ git grep -c '[.>]rx_over_errors ' -- drivers/ | wc -l
37

Plus those drivers are generally more modern than those
using rx_over_errors.

Since recently merged kernel documentation makes this
preference official, let's make ip -s output more informative
and let rx_missed_errors take the place of rx_over_errors.

Guillaume Nault a6c5c952ab ip link: initial support for bareudp devices
Bareudp devices provide a generic L3 encapsulation for tunnelling
different protocols like MPLS, IP, NSH, etc. inside a UDP tunnel.

This patch is based on original work from Martin Varghese:
https://lore.kernel.org/netdev/1570532361-15163-1-git-send-email-martinvarghesenokia@gmail.com/

Examples:

  - ip link add dev bareudp0 type bareudp dstport 6635 ethertype mpls_uc

This creates a bareudp tunnel device which tunnels L3 traffic with
ethertype 0x8847 (unicast MPLS traffic). The destination port of the
UDP header will be set to 6635. The device will listen on UDP port 6635
to receive traffic.

  - ip link add dev bareudp0 type bareudp dstport 6635 ethertype ipv4 multiproto

Same as the MPLS example, but for IPv4. The "multiproto" keyword allows
the device to also tunnel IPv6 traffic.

Xin Long 39fa047938 iproute_lwtunnel: add options support for erspan metadata
This patch is to add LWTUNNEL_IP_OPTS_ERSPAN's parse and print to implement
erspan options support in iproute_lwtunnel.

Option is expressed as version:index:dir:hwid, dir and hwid will be parsed
when version is 2, while index will be parsed when version is 1. All of
these are numbers. erspan doesn't support multiple options.

With this patch, users can add and dump erspan options like:

  # ip netns add a
  # ip netns add b
  # ip -n a link add eth0 type veth peer name eth0 netns b
  # ip -n a link set eth0 up
  # ip -n b link set eth0 up
  # ip -n a addr add 10.1.0.1/24 dev eth0
  # ip -n b addr add 10.1.0.2/24 dev eth0
  # ip -n b link add erspan1 type erspan key 1 seq erspan 123 \
    local 10.1.0.2 remote 10.1.0.1
  # ip -n b addr add 1.1.1.1/24 dev erspan1
  # ip -n b link set erspan1 up
  # ip -n b route add 2.1.1.0/24 dev erspan1
  # ip -n a link add erspan1 type erspan key 1 seq local 10.1.0.1 external
  # ip -n a addr add 2.1.1.1/24 dev erspan1
  # ip -n a link set erspan1 up
  # ip -n a route add 1.1.1.0/24 encap ip id 1 \
    erspan_opts 2:123:1:2 dst 10.1.0.2 dev erspan1
  # ip -n a route show
  # ip netns exec a ping 1.1.1.1 -c 1

   1.1.1.0/24  encap ip id 1 src 0.0.0.0 dst 10.1.0.2 ttl 0 tos 0
     erspan_opts 2:0:1:2 dev erspan1 scope link

   PING 1.1.1.1 (1.1.1.1) 56(84) bytes of data.
   64 bytes from 1.1.1.1: icmp_seq=1 ttl=64 time=0.124 ms

v1->v2:
  - improve the changelog.
  - use PRINT_ANY to support dumping with json format.
v2->v3:
  - implement proper JSON object for opts instead of just bunch of strings.
v3->v4:
  - keep the same format between input and output, json and non json.
  - print version, index, dir and hwid as uint.

This patch is to add LWTUNNEL_IP_OPTS_VXLAN's parse and print to implement

Xin Long ca7614d4c6 iproute_lwtunnel: add options support for geneve metadata
This patch is to add LWTUNNEL_IP(6)_OPTS and LWTUNNEL_IP_OPTS_GENEVE's
parse and print to implement geneve options support in iproute_lwtunnel.

listed using a comma delimiter, class and type are numbers and data
is a hex string.

With this patch, users can add and dump geneve options like:

  # ip netns add a
  # ip netns add b
  # ip -n a link add eth0 type veth peer name eth0 netns b
  # ip -n a link set eth0 up; ip -n b link set eth0 up

William Tu 846b6b2da8 erspan: Add type I version 0 support.
The Type I ERSPAN frame format is based on the barebones
IP + GRE(4-byte) encapsulation on top of the raw mirrored frame.
Both type I and II use 0x88BE as protocol type. Unlike type II
and III, no sequence number or key is required.

To creat a type I erspan tunnel device:
$ ip link add dev erspan11 type erspan \
	local 172.16.1.100 remote 172.16.1.200 \
	erspan_ver 0

Paolo Abeni 7e0767cd86 add support for mptcp netlink interface
Implement basic commands to:
- manipulate MPTCP endpoints list
- manipulate MPTCP connection limits

Examples:
1. Allows multiple subflows per MPTCP connection
   $ ip mptcp limits set subflows 2

2. Accept ADD_ADDR announcement from the peer (server):
   $ ip mptcp limits set add_addr_accepted 2

3. Add a ipv4 address to be annunced for backup subflows:
   $ ip mptcp endpoint add 10.99.1.2 signal backup

4. Add an ipv6 address used as source for additional subflows:
   $ ip mptcp endpoint add 2001::2 subflow

As commit f9d696cf41 ("xfrm: not try to delete ipcomp states when using

xsinfo->id.proto == IPPROTO_IPV6.

  # ip xfrm state add src 2000::1 dst 2000::2 spi 0x1000 \
    proto comp comp deflate mode tunnel sel src 2000::1 dst \

  # ip xfrm sta deleteall
  Failed to send delete-all request
  : Operation not permitted

Note that the xsinfo->proto in common states can never be IPPROTO_IPV6.

Mark Starovoytov bcbeb35ca4 macsec: add support for specifying offload at link add time
This patch adds support for configuring offload mode upon MACsec
device creation.

If offload mode is not specified, then netlink attribute is not
added. Default behavior on the kernel side in this case is
backward-compatible (offloading is disabled by default).

Example:
$ ip link add link eth0 macsec0 type macsec port 11 encrypt on offload mac

Petr Machata 20927e0525 ip: link_gre: Do not send ERSPAN attributes to GRE tunnels
In the commit referenced below, ip link started sending ERSPAN-specific
attributes even for GRE and gretap tunnels. Fix by more carefully
distinguishing between the GRE/tap and ERSPAN modes. Do not show
ERSPAN-related help in GRE/tap mode, likewise do not accept ERSPAN
arguments, or send ERSPAN attributes.
