iproute2: ip addr: Organize flag properties structurally
This creates a nice systematic way to check that the various flags are
mutable from userspace and that the address family is valid.
Mutability properties are preserved to avoid introducing any behavioral

This happens because asprintf allocates exactly the space needed to hold a
string in the buffer passed as its first argument, but if this buffer is later
used in strcat() or similar we have a buffer overrun.

tipc: enable printing of broadcast rcv link stats
This commit allows printing the statistics of a broadcast-receiver link
using the same tipc command, but with additional 'link' options:
$ tipc link stat show --help
Usage: tipc link stat show [ link { LINK | SUBSTRING | all } ]
With:
+ 'LINK' : print the stats of the specific link 'LINK';
+ 'SUBSTRING' : print the stats of all the links having the 'SUBSTRING'
in name;
+ 'all' : print all the links' stats incl. the broadcast-receiver
ones;
Also, a link stats can be reset in the usual way by specifying the link
name in command.
For example:
$ tipc l st sh l br
Link <broadcast-link>
Window:50 packets
RX packets:0 fragments:0/0 bundles:0/0
TX packets:5011125 fragments:4968774/149643 bundles:38402/307061
RX naks:781484 defs:0 dups:0
TX naks:0 acks:0 retrans:330259
Congestion link:50657 Send queue max:0 avg:0
Store the parsed count/offset pair count onto a dedicated variable that
will be compared against opt.num_tc after all of the command line
arguments were parsed. Bail out if this count is higher than opt.num_tc
and let user know about it.
Drivers were swallowing such commands as they were iterating over
count/offset pairs where num_tc was used as a delimiter, so this is not
a big deal, but better catch such misconfiguration at the command line
argument parsing level.

ss: add support for cgroup v2 information and filtering
This patch introduces two new features: obtaining cgroup information and
filtering sockets by cgroups. These features work based on cgroup v2 ID
field in the socket (kernel should be compiled with CONFIG_SOCK_CGROUP_DATA).
Cgroup information can be obtained by specifying --cgroup flag and now contains
only pathname. For faster pathname lookups cgroup cache is implemented. This
cache is filled on ss startup and missed entries are resolved and saved
on the fly.
Cgroup filter extends EXPRESSION and allows to specify cgroup pathname
(relative or absolute) to obtain sockets attached only to this cgroup.
Filter syntax: ss [ cgroup PATHNAME ]
Examples:
ss -a cgroup /sys/fs/cgroup/unified (or ss -a cgroup .)
ss -a cgroup /sys/fs/cgroup/unified/cgroup1 (or ss -a cgroup cgroup1)

iproute2-next:tc:action: add a gate control action
Introduce a ingress frame gate control flow action.
Tc gate action does the work like this:
Assume there is a gate allow specified ingress frames can pass at
specific time slot, and also drop at specific time slot. Tc filter
chooses the ingress frames, and tc gate action would specify what slot
does these frames can be passed to device and what time slot would be
dropped.
Tc gate action would provide an entry list to tell how much time gate
keep open and how much time gate keep state close. Gate action also
assign a start time to tell when the entry list start. Then driver would
repeat the gate entry list cyclically.
For the software simulation, gate action require the user assign a time
clock type.
Below is the setting example in user space. Tc filter a stream source ip
address is 192.168.0.20 and gate action own two time slots. One is last
200ms gate open let frame pass another is last 100ms gate close let
frames dropped.
# tc qdisc add dev eth0 ingress
# tc filter add dev eth0 parent ffff: protocol ip \
flower src_ip 192.168.0.20 \
action gate index 2 clockid CLOCK_TAI \
sched-entry open 200000000ns -1 8000000b \
sched-entry close 100000000ns
# tc chain del dev eth0 ingress chain 0
"sched-entry" follow the name taprio style. Gate state is
"open"/"close". Follow the period nanosecond. Then next -1 is internal
priority value means which ingress queue should put to. "-1" means
wildcard. The last value optional specifies the maximum number of
MSDU octets that are permitted to pass the gate during the specified
time interval, the overlimit frames would be dropped.
Below example shows filtering a stream with destination mac address is
10:00:80:00:00:00 and ip type is ICMP, follow the action gate. The gate
action would run with one close time slot which means always keep close.
The time cycle is total 200000000ns. The base-time would calculate by:
ip link add br0 type bridge
ip link add vx0 type vxlan dstport 4789 external
ip link set dev vx0 master br0
bridge vlan del vid 1 dev vx0
ip link add vx1 type vxlan dstport 4790 external
ip link set dev vx1 master br0
root@vsid:/src/iproute2# ./bridge/bridge vlan
port vlan-id
br0 1 PVID Egress Untagged
Why does vx0 appear in normal output and not json output?
Why output an empty list for br0 and vx1?
Fix these inconsistencies and avoid outputting entries with no values. This
makes the behavior consistent with other iproute2 commands, for example
`ip -6 addr`: if an interface doesn't have any ipv6 addresses, it is not
part of the listing.

xfrm: also check for ipv6 state in xfrm_state_keep
As commit f9d696cf414c ("xfrm: not try to delete ipcomp states when using
deleteall") does, this patch is to fix the same issue for ip6 state where
xsinfo->id.proto == IPPROTO_IPV6.

Failed to send delete-all request
: Operation not permitted
Note that the xsinfo->proto in common states can never be IPPROTO_IPV6.

Merge branch 'macsec-offload' into next
Igor Russkikh says:
====================
From: Mark Starovoytov <mstarovoitov@marvell.com>
This series adds support for selecting the offloading mode of a MACsec
interface at link creation time.
Available modes are for now 'off', 'phy' and 'mac', 'off' being the default
when an interface is created.
First patch adds support for MAC offloading.
Last patch allows a user to change the offloading mode at runtime
through a new attribute, `ip link add link ... offload`:
# ip link add link enp1s0 type macsec encrypt on offload off
# ip link add link enp1s0 type macsec encrypt on offload phy
# ip link add link enp1s0 type macsec encrypt on offload mac

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

tc: fq_codel: fix class stat deficit is signed int
The fq_codel class stat deficit is a signed int. This is a regression
from when JSON output was added.

This will help avoid overflow, since setting it to 0xffffffff would
result in -1 when converted to integer, resulting in being "-1", setting
the fwmark to 0x00.
This detects overflow during parsing of value using get_size:
eg. running:
$ tc qdisc add dev lo root cake memlimit 11gb
currently gives a memlimit of "3072Mb", while with this patch it errors
with 'illegal value for "memlimit": "11gb"', since memlinit is an
unsigned integer.
