Extend slotting with support for non-uniform distributions. This is
similar to netem's non-uniform distribution delay feature.
Syntax:
slot distribution DISTRIBUTION DELAY JITTER [packets MAX_PACKETS] \
[bytes MAX_BYTES]
The syntax and use of the distribution table is the same as in the
non-uniform distribution delay feature. A file DISTRIBUTION must be
present in TC_LIB_DIR (e.g. /usr/lib/tc) containing numbers scaled by
NETEM_DIST_SCALE. A random value x is selected from the table and it
takes DELAY + ( x * JITTER ) as delay. Correlation between values is not
supported.
Examples:
Normal distribution delay with mean = 800us and stdev = 100us.
> tc qdisc add dev eth0 root netem slot distribution normal \
800us 100us
Optionally set the max slot size in bytes and/or packets.
> tc qdisc add dev eth0 root netem slot distribution normal \
800us 100us bytes 64k packets 42

Slotting is a crude approximation of the behaviors of shared media such
as cable, wifi, and LTE, which gather up a bunch of packets within a
varying delay window and deliver them, relative to that, nearly all at
once.
It works within the existing loss, duplication, jitter and delay
parameters of netem. Some amount of inherent latency must be specified,
regardless.
The new "slot" parameter specifies a minimum and maximum delay between
transmission attempts.
The "bytes" and "packets" parameters can be used to limit the amount of
information transferred per slot.
Examples of use:
tc qdisc add dev eth0 root netem delay 200us \
slot 800us 10ms bytes 64k packets 42
A more correct example, using stacked netem instances and a packet limit
to emulate a tail drop wifi queue with slots and variable packet
delivery, with a 200Mbit isochronous underlying rate, and 20ms path
delay:
tc qdisc add dev eth0 root handle 1: netem delay 20ms rate 200mbit \
limit 10000
tc qdisc add dev eth0 parent 1:1 handle 10:1 netem delay 200us \
slot 800us 10ms bytes 64k packets 42 limit 512

sch_skbprio is a qdisc that prioritizes packets according to their skb->priority

sch_cake is intended to squeeze the most bandwidth and latency out of even
the slowest ISP links and routers, while presenting an API simple enough
that even an ISP can configure it.
Example of use on a cable ISP uplink:
tc qdisc add dev eth0 cake bandwidth 20Mbit nat docsis ack-filter
To shape a cable download link (ifb and tc-mirred setup elided)
tc qdisc add dev ifb0 cake bandwidth 200mbit nat docsis ingress wash besteffort
Cake is filled with:
* A hybrid Codel/Blue AQM algorithm, "Cobalt", tied to an FQ_Codel
derived Flow Queuing system, which autoconfigures based on the bandwidth.
* A novel "triple-isolate" mode (the default) which balances per-host
and per-flow FQ even through NAT.
* An deficit based shaper, that can also be used in an unlimited mode.
* 8 way set associative hashing to reduce flow collisions to a minimum.
* A reasonable interpretation of various diffserv latency/loss tradeoffs.
* Support for zeroing diffserv markings for entering and exiting traffic.
* Support for interacting well with Docsis 3.0 shaper framing.
* Support for DSL framing types and shapers.
* Support for ack filtering.
* Extensive statistics for measuring, loss, ecn markings, latency variation.
Various versions baking have been available as an out of tree build for
kernel versions going back to 3.10, as the embedded router world has been
running a few years behind mainline Linux. A stable version has been
generally available on lede-17.01 and later.
sch_cake replaces a combination of iptables, tc filter, htb and fq_codel
in the sqm-scripts, with sane defaults and vastly simpler configuration.
Cake's principal author is Jonathan Morton, with contributions from
Kevin Darbyshire-Bryant, Toke Høiland-Jørgensen, Sebastian Moeller,
Ryan Mounce, Tony Ambardar, Dean Scarff, Nils Andreas Svee, Dave Täht,
and Loganaden Velvindron.

Devlink region allows access to driver defined address regions.
Each device can create its supported address regions and register
them. A device which exposes a region will allow access to it
using devlink.
This support allows reading and dumping regions snapshots as well
as presenting information such as region size and current available
snapshots.
A snapshot represents a memory image of a region taken by the driver.
If a device collects a snapshot of an address region it can be later
exposed using devlink region read or dump commands.
This functionality allows for future analyses on the snapshots.
The dump command is designed to read the full address space of a
region or of a snapshot unlike the read command which allows
reading only a specific section in a region/snapshot indicated by
an address and a length, current support is for reading and dumping
for a previously taken snapshot ID.
New commands added:
devlink region show [ DEV/REGION ]
devlink region delete DEV/REGION snapshot SNAPSHOT_ID
devlink region dump DEV/REGION [ snapshot SNAPSHOT_ID ]
devlink region read DEV/REGION [ snapshot SNAPSHOT_ID ]

Users have reported a regression due to ip now dropping capabilities
unconditionally.

does not work anymore.
As a workaround, do not drop caps if CAP_NET_ADMIN (the most common

Users that want ip vrf exec to work do not need to set INHERITABLE,
which will then only set when the calling program had privileges to
give itself the ambient capability.

Current supported use case is classification based on the incoming IPSec
state used during decpsulation using the 'policy' iptables extension
(xt_policy).
The matcher uses libxtables for parsing the input parameters.
Example use for matching an IPSec state with reqid 1:
tc qdisc add dev eth0 ingress
tc filter add dev eth0 protocol ip parent ffff: \
basic match 'ipt(-m policy --dir in --pol ipsec --reqid 1)' \

For IP-in-IP tunnels, one can specify the [no]allow-localremote command

IP6_TNL_F_ALLOW_LOCAL_REMOTE flag on the netdevice. However, ip6gretap
and ip6erspan devices, where the flag is also relevant, are not IP-in-IP

netdevices. Therefore introduce the command to link_gre6 as well.

If the kernel receives a negative nsid it will automatically assign
the next available nsid. In this case alloc_netid() will set min and
max to 0 for ird_alloc(). And when max == 0 idr_alloc() will interpret
this as the maximum range, i.e. specific to nsids it will try to find
an id in the range [0,INT_MAX). This is intentionally supported in the
kernel for nsids.
Commit acbe9118ce ("ip netns: use strtol() instead of atoi()")
regressed ip netns in that respect although previously the use-case
was either accidentally supported or opaquely supported such that it
triggered the original commit. From what I can gather it went as
follows before: atoi() was called with a string indicating a negative
value which caused it to return -1 which was passed to the
kernel. Let's make it less opaque by introducing the keyword "auto":
ip netns set <netns-name> auto
will cause nsid to be set to -1 and the kernel will select an available
nsid.

The patch adds support for configuring the erspan v2, for both

are added: 'erspan_ver' for distinguishing v1 or v2, 'erspan_dir'
for specifying direction of the mirrored traffic, and 'erspan_hwid'
for users to set ERSPAN engine ID within a system.
As for manpage, the ERSPAN descriptions used to be under GRE, IPIP,
SIT Type paragraph. Since IP6GRE/IP6GRETAP also supports ERSPAN,
the patch removes the old one, creates a separate ERSPAN paragrah,

This patch adapts the tc command line interface to allow bandwidth limits
to be specified as a percentage of the interface's capacity.
Adding this functionality requires passing the specified device string to
each class/qdisc which changes the prototype for a couple of functions: the
.parse_qopt and .parse_copt interfaces. The device string is a required
parameter for tc-qdisc and tc-class, and when not specified, the kernel
returns ENODEV. In this patch, if the user tries to specify a bandwidth
percentage without naming the device, we return an error from userspace.

integer is comparable to an IP address. AF_VSOCK ports work like

'ip vrf' follows the user semnatics established by 'ip netns'.
The 'ip vrf' subcommand supports 3 usages:
1. Run a command against a given vrf:
ip vrf exec NAME CMD
Uses the recently committed cgroup/sock BPF option. vrf directory
is added to cgroup2 mount. Individual vrfs are created under it. BPF
filter attached to vrf/NAME cgroup2 to set sk_bound_dev_if to the VRF
device index. From there the current process (ip's pid) is addded to
the cgroups.proc file and the given command is exected. In doing so
all AF_INET/AF_INET6 (ipv4/ipv6) sockets are automatically bound to
the VRF domain.
The association is inherited parent to child allowing the command to
be a shell from which other commands are run relative to the VRF.
2. Show the VRF a process is bound to:
ip vrf id
This command essentially looks at /proc/pid/cgroup for a "::/vrf/"
entry with the VRF name following.
3. Show process ids bound to a VRF
ip vrf pids NAME
This command dumps the file MNT/vrf/NAME/cgroup.procs since that file
shows the process ids in the particular vrf cgroup.

Now that we made the BPF loader generic as a library, reuse it
for loading XDP programs as well. This basically adds a minimal
start of a facility for iproute2 to load XDP programs. There
currently only exists the xdp1_user.c sample code in the kernel
tree that sets up netlink directly and an iovisor/bcc front-end.
Since we have all the necessary infrastructure in place already
from tc side, we can just reuse its loader back-end and thus
facilitate migration and usability among the two for people
familiar with tc/bpf already. Sharing maps, performing tail calls,
etc works the same way as with tc. Naturally, once kernel
configuration API evolves, we will extend new features for XDP
here as well, resp. extend dumping of related netlink attributes.
Minimal example:
clang -target bpf -O2 -Wall -c prog.c -o prog.o
ip [-force] link set dev em1 xdp obj prog.o # attaching
ip [-d] link # dumping
ip link set dev em1 xdp off # detaching
For the dump, intention is that in the first line for each ip
link entry, we'll see "xdp" to indicate that this device has an
XDP program attached. Once we dump some more useful information
via netlink (digest, etc), idea is that 'ip -d link' will then
display additional relevant program information below the "link/
ether [...]" output line for such devices, for example.

This action could be used before redirecting packets to a shared tunnel
device, or when redirecting packets arriving from a such a device.
The 'unset' action is optional. It is used to explicitly unset the
metadata created by the tunnel device during decap. If not used, the
metadata will be released automatically by the kernel.
The 'set' operation, will set the metadata with the specified values for
the encap.
For example, the following flower filter will forward all ICMP packets
destined to 11.11.11.2 through the shared vxlan device 'vxlan0'. Before
redirecting, a metadata for the vxlan tunnel is created using the
tunnel_key action and it's arguments:

Introduce a new API that exposes a list of vlans per VF (IFLA_VF_VLAN_LIST),
giving the ability for user-space application to specify it for the VF as
an option to support 802.1ad (VST QinQ).
We introduce struct vf_vlan_info, which extends struct vf_vlan and adds
an optional VF VLAN proto parameter.
Default VLAN-protocol is 802.1Q.
Add IFLA_VF_VLAN_LIST in addition to IFLA_VF_VLAN to keep backward
compatibility with older kernel versions.
Suitable ip link tool command examples:
- Set vf vlan protocol 802.1ad (S-TAG)
ip link set eth0 vf 1 vlan 100 proto 802.1ad
- Set vf vlan S-TAG and vlan C-TAG (VST QinQ)
ip link set eth0 vf 1 vlan 100 proto 802.1ad vlan 30 proto 802.1Q
- Set vf to VST (802.1Q) mode

Looks like the real issue is missing definition of priority. What about
this:
use get_be64() in place of get_u64() when parsing input 'sci' parameter,
so that 'sci' can be entered using network byte order regardless the
endianness of target system; use ntohll() when printing out 'sci'. While
at it, improve documentation of 'sci' in ip-link.8.

In this patch we introduce the ability to get UDP specific bearer
options such as remoteip, remoteport, localip and localport.
After some discussions on tipc-discussion on how to handle media
specific options we agreed to pass them after the media.
For media generic bearer options we already do:
$ tipc bearer get OPTION media MEDIA name|device NAME|DEVICE
For the UDP media specific bearer options we introduce in this path:
$ tipc bearer get media udp name NAME OPTION
such as
$ tipc bearer get media udp name NAME remoteip
This allows bash-completion to tab complete only appropriate options,
it makes more logical sense and it scales better. Even though it might
look a little different to the user.
In order to use the existing option parsing framework to do this we
add a flag (OPT_KEY) to the option parsing function.
If the UDP bearer has multiple remoteip addresses associated with it
(replicast) we handle the TIPC_NLA_UDP_MULTI_REMOTEIP flag and send
a TIPC_NL_UDP_GET_REMOTEIP query transparently to the user.

This patch adds support for the stats argument to the bridge
vlan command which will display the per-vlan statistics and the device
each vlan belongs to with its flags. The supported command filtering
options are dev and vid. Also the man page is updated to explain the new
option.
The patch uses the new RTM_GETSTATS interface with a filter_mask to dump
all bridges and ports vlans. Later we can add support for using the
per-device dump and filter it in the kernel instead.
Example:
$ bridge -s vlan show
port vlan id
br0 1 Egress Untagged
RX: 2536 bytes 20 packets
TX: 2536 bytes 20 packets
101
RX: 43158 bytes 50 packets
TX: 43158 bytes 50 packets
eth1 1 Egress Untagged
RX: 2536 bytes 20 packets
TX: 2536 bytes 20 packets
100
RX: 0 bytes 0 packets
TX: 0 bytes 0 packets
101
RX: 43158 bytes 50 packets
TX: 43158 bytes 50 packets
102
RX: 16897 bytes 93 packets
TX: 0 bytes 0 packets
The format is the same as bridge vlan show but with stats, even though
under the hood the calls done to the kernel are different.
