b37a863cb2 devlink: remove custom bool command line options parsing
Change the code that is doing custom processing of boolean command line
options to use dl_argv_bool(). Extend strtobool() to accept
"enable"/"disable" to maintain current behavior.

02a2a6683f devlink: Add ability to bind policer to trap group
Add ability to associate a policer with a trap group. The policer can be
unbound by using the 'nopolicer' keyword. In which case, the value
encoded in the 'DEVLINK_ATTR_TRAP_POLICER_ID' attribute will be '0'.
This is consistent with ip-link 'nomaster' keyword and the 'IFLA_MASTER'
attribute.

Example:

# devlink trap group set netdevsim/netdevsim10 group l3_drops policer 2
# devlink -jp trap group show netdevsim/netdevsim10 group l3_drops
{
    "trap_group": {
        "netdevsim/netdevsim10": [ {
                "name": "l3_drops",
                "generic": true,
                "policer": 2
            } ]
    }
}

# devlink trap group set netdevsim/netdevsim10 group l3_drops nopolicer
# devlink -jp trap group show netdevsim/netdevsim10 group l3_drops
{
    "trap_group": {
        "netdevsim/netdevsim10": [ {

a66af55693 devlink: Add devlink trap policer set and show commands
The trap policer set command allows the user to set the parameters of
the packet trap policer, such as rate and burst size. Example:

# devlink trap policer set netdevsim/netdevsim10 policer 1 rate 1000 burst 32

The trap policer show command allows the user to get the current
parameters of an individual policer or a dump of all policers in case
one is not specified. When '-s' is specified the policer's statistics
are shown. Example:

# devlink -jps trap policer show netdevsim/netdevsim10 policer 1
{
    "trap_policer": {
        "netdevsim/netdevsim10": [ {
                "policer": 1,
                "rate": 1000,

341903dd3b tc: m_action: introduce support for hw stats type
Introduce support for per-action hw stats type config.

This patch allows user to specify one of the following types of HW
stats for added action:
immediate - queried during dump time
delayed - polled from HW periodically or sent by HW in async manner
disabled - no stats needed

Note that if "hw_stats" option is not passed, user does not care about
the type, just expects any type of stats.

Examples:
$ tc filter add dev enp0s16np28 ingress proto ip handle 1 pref 1 flower skip_sw dst_ip 192.168.1.1 action drop hw_stats disabled

72cc0bafb9 iproute2: fix MPLS label parsing
The initial value of "label" in parse_mpls() is 0xffffffff. Therefore
we should test for this value, and not 0, to detect if a label has been
provided. The "!label" test not only fails to detect a missing label
parameter, it also prevents the use of the IPv4 explicit NULL label,
which actually equals 0.

Reproducer:
  $ ip link add name dm0 type dummy
  $ tc qdisc add dev dm0 ingress

  $ tc filter add dev dm0 parent ffff: matchall action mpls push
  Error: act_mpls: Label is required for MPLS push.
  We have an error talking to the kernel
  --> Filter was pushed to the kernel, where it got rejected.

  $ tc filter add dev dm0 parent ffff: matchall action mpls push label 0
  Error: argument "label" is required
  --> Label 0 was rejected by iproute2.

Expected result:
  $ tc filter add dev dm0 parent ffff: matchall action mpls push
  Error: argument "label" is required
  --> Filter was directly rejected by iproute2.

  $ tc filter add dev dm0 parent ffff: matchall action mpls push label 0
  --> Filter is accepted.

ad19a18e42 Merge branch 'macsec-offload' into next
Antoine Tenart  says:

====================

This series adds support for selecting and reporting the offloading mode
of a MACsec interface. Available modes are for now 'off' and 'phy',
'off' being the default when an interface is created. Modes are not only
'off' and 'on' as the MACsec operations can be offloaded to multiple
kinds of specialized hardware devices, at least to PHYs and Ethernet
MACs. The later isn't currently supported in the kernel though.

The first patch adds support for reporting the offloading mode currently
selected for a given MACsec interface through the `ip macsec show`
command:

   # ip macsec show
   18: macsec0: protect on validate strict sc off sa off encrypt on send_sci on end_station off scb off replay off
       cipher suite: GCM-AES-128, using ICV length 16
       TXSC: 3e5035b67c860001 on SA 0
           0: PN 1, state on, key 00000000000000000000000000000000
       RXSC: b4969112700f0001, state on
           0: PN 1, state on, key 01000000000000000000000000000000
->     offload: phy
   19: macsec1: protect on validate strict sc off sa off encrypt on send_sci on end_station off scb off replay off
       cipher suite: GCM-AES-128, using ICV length 16
       TXSC: 3e5035b67c880001 on SA 0
           1: PN 1, state on, key 00000000000000000000000000000000
       RXSC: b4969112700f0001, state on
           1: PN 1, state on, key 01000000000000000000000000000000
->     offload: off

The second patch allows an user to change the offloading mode at runtime
through a new subcommand, `ip macsec offload`:

  # ip macsec offload macsec0 phy
  # ip macsec offload macsec0 off

If a mode isn't supported, `ip macsec offload` will report an issue
(-EOPNOTSUPP).

Giving the offloading mode when a macsec interface is created was
discussed; it is not implemented in this series. It could come later
on, when needed, as we'll still want to support updating the offloading
mode at runtime (what's implemented in this series).

MacSEC can now be offloaded to specialized hardware devices. Offloading
is off by default when creating a new MACsec interface, but the mode can
be updated at runtime. This patch adds a new subcommand,
`ip macsec offload`, to allow users to select the offloading mode of a
MACsec interface. It takes the mode to switch to as an argument, which
can for now either be 'off' or 'phy':

  # ip macsec offload macsec0 phy
  # ip macsec offload macsec0 off

states out, and it causes errors:

Currently `ip -6 route show` gives us this output:

sharpd@eva ~/i/ip (master)> ip -6 route show
::1 dev lo proto kernel metric 256 pref medium
4:5::6:7 nhid 18 proto static metric 20
        nexthop via fe80::99 dev enp39s0 weight 1
        nexthop via fe80::44 dev enp39s0 weight 1 pref medium

Displaying `pref medium` as the last bit of output implies
that the RTA_PREF is a per nexthop value, when it is infact
a per route piece of data.

Change the output to display RTA_PREF and RTA_TTL_PROPAGATE
before the RTA_MULTIPATH data is shown:

sharpd@eva ~/i/ip (master)> ./ip -6 route show
::1 dev lo proto kernel metric 256 pref medium
4:5::6:7 nhid 18 proto static metric 20 pref medium
        nexthop via fe80::99 dev enp39s0 weight 1
        nexthop via fe80::44 dev enp39s0 weight 1

2c7056ac26 nstat: print useful error messages in abort() cases
When nstat temporary file is corrupted or in some other corner cases,
nstat use abort() to stop its execution. This can puzzle some users,
wondering what is the reason for the crash.

This commit replaces abort() with some meaningful error messages and exit()

83c543af87 erspan: set erspan_ver to 1 by default
Commit 2897636267 ("erspan: add erspan version II support")
breaks the command:

 # ip link add erspan1 type erspan key 1 seq erspan 123 \
    local 10.1.0.2 remote 10.1.0.1

as erspan_ver is set to 0 by default, then IFLA_GRE_ERSPAN_INDEX
won't be set in gre_parse_opt().

  # ip -d link show erspan1
    ...
    erspan remote 10.1.0.1 local 10.1.0.2 ... erspan_index 0 erspan_ver 1
                                              ^^^^^^^^^^^^^^

This patch is to change to set erspan_ver to 1 by default.

9dced637f8 tc: add support for FQ-PIE packet scheduler
This patch adds support for the FQ-PIE packet Scheduler

Principles:
  - Packets are classified on flows.
  - This is a Stochastic model (as we use a hash, several flows might
                                be hashed to the same slot)
  - Each flow has a PIE managed queue.
  - Flows are linked onto two (Round Robin) lists,
    so that new flows have priority on old ones.
  - For a given flow, packets are not reordered.
  - Drops during enqueue only.
  - ECN capability is off by default.
  - ECN threshold (if ECN is enabled) is at 10% by default.
  - Uses timestamps to calculate queue delay by default.

Usage:
tc qdisc ... fq_pie [ limit PACKETS ] [ flows NUMBER ]
                    [ target TIME ] [ tupdate TIME ]
                    [ alpha NUMBER ] [ beta NUMBER ]
                    [ quantum BYTES ] [ memory_limit BYTES ]
                    [ ecn_prob PERCENTAGE ] [ [no]ecn ]
                    [ [no]bytemode ] [ [no_]dq_rate_estimator ]

defaults:
  limit: 10240 packets, flows: 1024
  target: 15 ms, tupdate: 15 ms (in jiffies)
  alpha: 1/8, beta : 5/4
  quantum: device MTU, memory_limit: 32 Mb
  ecnprob: 10%, ecn: off
  bytemode: off, dq_rate_estimator: off

38dd041bfe ip-xfrm: Fix help messages
After commit 8589eb4efd ("treewide: refactor help messages") help
messages for xfrm state and policy are broken, printing many times the
same protocol in UPSPEC section:

$ ip xfrm state help
[...]
UPSPEC := proto { { tcp | tcp | tcp | tcp } [ sport PORT ] [ dport PORT ] |
                  { icmp | icmp | icmp } [ type NUMBER ] [ code NUMBER ] |
                  gre [ key { DOTTED-QUAD | NUMBER } ] | PROTO }

This happens because strxf_proto function is non-reentrant and gets called
multiple times in the same fprintf instruction.

This commit fix the issue avoiding calls to strxf_proto() with a constant
param, just hardcoding strings for protocol names.
