This patch adds the support for the reduced version of the H.Encaps and
H.L2Encaps behaviors as defined in RFC 8986 [1].
H.Encaps.Red and H.L2Encaps.Red SRv6 behaviors are an optimization of the
H.Encaps and H.L2Encaps aiming to reduce the length of the SID List carried
in the pushed SRH. Specifically, the reduced version of the behaviors
removes the first SID contained in the SID List (i.e. SRv6 Policy) by
storing it into the IPv6 Destination Address. When SRv6 Policy is made of
only one SID, the reduced version of the behaviors omits the SRH at all and
pushes that SID directly into the IPv6 DA.
Some examples:
ip -6 route add 2001:db8::1 encap seg6 mode encap.red segs fcf0:1::e,fcf0:2::d6 dev eth0
ip -6 route add 2001:db8::2 encap seg6 mode l2encap.red segs fcf0:1::d2 dev eth0
Standard Output:
ip -6 route show 2001:db8::1
2001:db8::1 encap seg6 mode encap.red segs 2 [ fcf0:1::e fcf0:2::d6 ] dev eth0 metric 1024 pref medium
JSON Output:
ip -6 -j -p route show 2001:db8::1
[ {
"dst": "2001:db8::1",
"encap": "seg6",
"mode": "encap.red",
"segs": [ "fcf0:1::e","fcf0:2::d6" ],

Introduce PPPoE specific fields in tc-flower:
- session id (16 bits)
- ppp protocol (16 bits)
Those fields can be provided only when protocol was set to
ETH_P_PPP_SES. ppp_proto works similar to vlan_ethtype, i.e.
ppp_proto overwrites eth_type. Thanks to that, fields from
encapsulated protocols (such as src_ip) can be specified.
e.g.
# tc filter add dev ens6f0 ingress prio 1 protocol ppp_ses \
flower \
pppoe_sid 1234 \
ppp_proto ip \
dst_ip 127.0.0.1 \
src_ip 127.0.0.2 \
action drop
Vlan and cvlan is also supported, in this case cvlan_ethtype
or vlan_ethtype has to be set to ETH_P_PPP_SES.
e.g.
# tc filter add dev ens6f0 ingress prio 1 protocol 802.1Q \
flower \
vlan_id 2 \
vlan_ethtype ppp_ses \
pppoe_sid 1234 \
ppp_proto ip \

The tc-fw filter can be used to match on the packet's fwmark by adding a
filter with a matching handle. It also supports matching on specific
bits of the fwmark by specifying the handle together with a mask. This
is documented in the usage message below, but not in the man page.
Document it in the man page together with an example.
$ tc filter add fw help
Usage: ... fw [ classid CLASSID ] [ indev DEV ] [ action ACTION_SPEC ]
CLASSID := Push matching packets to the class identified by CLASSID with format X:Y
CLASSID is parsed as hexadecimal input.
DEV := specify device for incoming device classification.
ACTION_SPEC := Apply an action on matching packets.
NOTE: handle is represented as HANDLE[/FWMASK].
FWMASK is 0xffffffff by default.

Usually we match on the device specified after "dev" but there are
special cases where we need an additional device attribute for matching
such as when matching entries specifically pointing to the bridge device
itself. We use NDA_IFINDEX for that purpose.
Example:
$ bridge fdb flush dev br0 brport br0
This will flush only entries pointing to the bridge itself.
$ bridge fdb flush dev swp1 brport swp2 master
Note this will flush entries pointing to swp2 only. The NDA_IFINDEX
attribute overrides the dev argument. This is documented in the man

The -p, -Z and -z options only show process (thread group leader)
information. For example, if the thread group leader has exited, but
another thread in the group is still using a socket, ss -[pZz] does not
show it.
Add a new option, -T (--threads), to show thread information. It implies
the -p option. For example, imagine process A and thread B (in the same
group) using the same socket. ss -p only shows A:
$ ss -ltp "sport = 1234"
State Recv-Q Send-Q Local Address:Port Peer Address:Port Process
LISTEN 0 100 0.0.0.0:1234 0.0.0.0:* users:(("test",pid=2932547,fd=3))
ss -T shows A and B:
$ ss -ltT "sport = 1234"
State Recv-Q Send-Q Local Address:Port Peer Address:Port Process
LISTEN 0 100 0.0.0.0:1234 0.0.0.0:* users:(("test",pid=2932547,tid=2932548,fd=3),("test",pid=2932547,tid=2932547,fd=3))
If -T is used, -Z and -z also show SELinux contexts for threads.
Rename some variables (from "process" to "task", for example) since we
use them for both processes and threads.

To show statistics nested under IFLA_STATS_LINK_XSTATS_SLAVE or

attribute, then "subgroup" to select the link type, which is itself a nest,
and then would lack a way to denote which attribute to select out of the
link-type nest.
To that end, add the selector level "suite", which is filtered in the

this patch set address a slight omission in controlling broadcast

option, instead of breaking the two mcast options. Unfortunately
the other options are not alphabetically sorted, so this was the
least worst option. (Stephen)
- Add missing closing " for 'bridge mdb show' in bridge(8) SYNOPSIS

- Update man page for ip-link(8) with new bcast_flood flag
- Update mcast_flood in same man page slightly
