[ Upstream commit aa709da0e032cee7c202047ecd75f437bb0126ed ]
Since commit 1033990ac5 ("sctp: implement memory accounting on tx path"),
SCTP has supported memory accounting on tx path where 'sctp_wmem' is used
by sk_wmem_schedule(). So we should fix the description for this option in
ip-sysctl.rst accordingly.
v1->v2:
- Improve the description as Marcelo suggested.

and associated inet_is_local_unbindable_port() helper function:
use it to make explicitly binding to an unbindable port return
-EPERM 'Operation not permitted'.
Autobind doesn't honour this new sysctl since:
(a) you can simply set both if that's the behaviour you desire
(b) there could be a use for preventing explicit while allowing auto
(c) it's faster in the relatively critical path of doing port selection
during connect() to only check one bitmap instead of both
Various ports may have special use cases which are not suitable for
use by general userspace applications. Currently, ports specified in
ip_local_reserved_ports sysctl will not be returned only in case of
automatic port assignment, but nothing prevents you from explicitly
binding to them - even from an entirely unprivileged process.
In certain cases it is desirable to prevent the host from assigning the
ports even in case of explicit binds, even from superuser processes.
Example use cases might be:
- a port being stolen by the nic for remote serial console, remote
power management or some other sort of debugging functionality
(crash collection, gdb, direct access to some other microcontroller
on the nic or motherboard, remote management of the nic itself).
- a transparent proxy where packets are being redirected: in case
a socket matches this connection, packets from this application
would be incorrectly sent to one of the endpoints.
Initially I wanted to solve this problem via the simple one line:
static inline bool inet_port_requires_bind_service(struct net *net, unsigned short port) {
- return port < net->ipv4.sysctl_ip_prot_sock;
+ return port < net->ipv4.sysctl_ip_prot_sock || inet_is_local_reserved_port(net, port);
}
However, this doesn't work for two reasons:
(a) it changes userspace visible behaviour of the existing local
reserved ports sysctl, and there appears to be enough documentation
on the internet talking about setting it to make this a bad idea
(b) it doesn't prevent privileged apps from using these ports,
CAP_BIND_SERVICE is relatively likely to be available to, for example,
a recursive DNS server so it can listed on port 53, which also needs
to do src port randomization for outgoing queries due to security
reasons (and it thus does manual port binding).
If we *know* that certain ports are simply unusable, then it's better
nothing even gets the opportunity to try to use them. This way we at
least get a quick failure, instead of some sort of timeout (or possibly
even corruption of the data stream of the non-kernel based use case).
Test:
vm:~# cat /proc/sys/net/ipv4/ip_local_unbindable_ports
vm:~# python -c 'import socket; s = socket.socket(socket.AF_INET6, socket.SOCK_STREAM, 0); s.bind(("::", 3967))'
vm:~# python -c 'import socket; s = socket.socket(socket.AF_INET6, socket.SOCK_DGRAM, 0); s.bind(("::", 3967))'

Commit a296d665ea ("ixgbe: Add ethtool support to enable 2.5 and 5.0
Gbps support") introduced suppression of the advertisement of NBASE-T
speeds by default, according to Todd Fujinaka to accommodate customers
with network switches which could not cope with advertised NBASE-T
speeds, as posted in the E1000-devel mailing list:
https://sourceforge.net/p/e1000/mailman/message/37106269/
However, the suppression was not documented at all, nor was how to
enable NBASE-T support.
Properly document the NBASE-T suppression and how to enable NBASE-T
support.

There are many features in the driver that depend on the major, minor,
and patch version of the FW. Without the patch number in the output for
fw.mgmt.api debugging issues related to the FW API version is difficult.
Also, using major.minor.patch aligns with the existing firmware version
which uses a 3 digit value.
Fix this by making the fw.mgmt.api print the major.minor.patch
versions. Shown below is the result:

conntrack has two distinct table size settings:
nf_conntrack_max and nf_conntrack_buckets.
The former limits how many conntrack objects are allowed to exist
in each namespace.
The second sets the size of the hashtable.
As all entries are inserted twice (once for original direction, once for
reply), there should be at least twice as many buckets in the table than
the maximum number of conntrack objects that can exist at the same time.
Change the default multiplier to 1 and increase the chosen bucket sizes.
This results in the same nf_conntrack_max settings as before but reduces
the average bucket list length.

mlx5-updates-2021-08-19
This series introduces the support for two new mlx5 features:
1) Sample offload for tunneled traffic
2) devlink rate objects support
1) From Chris Mi: Sample offload for tunneled traffic
=====================================================
Background and solution
-----------------------
Currently the sample offload actions send the encapsulated packet
to software. This series de-capsulates the packet before performing
the sampling and set the tunnel properties on the skb metadata
fields to make the behavior consistent with OVS sFlow.
If de-capsulating first, we can't use the same match like before in
default table. So instantiate a post action instance to continue
processing the action list. If HW can preserve reg_c, also use the
post action instance.
Post action infrastructure
--------------------------
Some tc actions are modeled in hardware using multiple tables
causing a tc action list split. For example, CT action is modeled
by jumping to a ct table which is controlled by nf flow table.
sFlow jumps in hardware to a sample table, which continues to a
"default table" where it should continue processing the action list.
Multi table actions are modeled in hardware using a unique fte_id.
The fte_id is set before jumping to a table. Split actions continue
to a post-action table where the matched fte_id value continues the
execution the tc action list.
This series also introduces post action infrastructure. Both ct and
sample use it.
Sample for tunnel in TC SW
--------------------------
tc filter add dev vxlan1 protocol ip parent ffff: prio 3 \
flower src_mac 24:25:d0:e1:00:00 dst_mac 02:25:d0:13:01:02 \
enc_src_ip 192.168.1.14 enc_dst_ip 192.168.1.13 \
enc_dst_port 4789 enc_key_id 4 \
action sample rate 1 group 6 \
action tunnel_key unset \
action mirred egress redirect dev enp4s0f0_1
MLX5 sample HW offload
----------------------
For the following typical flow table:
+-------------------------------+
+ original flow table +
+-------------------------------+
+ original match +
+-------------------------------+
+ sample action + other actions +
+-------------------------------+
We translate the tc filter with sample action to the following HW model:
+---------------------+
+ original flow table +
+---------------------+
+ original match +
+---------------------+
| set fte_id (if reg_c preserve cap)

2) From Dmytro Linkin: devlink rate object support for mlx5_core driver
=======================================================================
HIGH-LEVEL OVERVIEW
Devlink leaf rate objects created per vport (VF/SF, and PF on BlueField)
in switchdev mode on devlink port registration.
Implement devlink ops callbacks to create/destroy rate groups, set TX
rate values of the vport/group, assign vport to the group.
Driver accepts TX rate values as fraction of 1Mbps.
Refactor existing eswitch QoS infrastructure to be accessible by legacy
NDO rate API and new devlink rate API. NDO rate API is not
removed/disabled in switchdev mode to not break existing users. Rate
values configured with NDO rate API are not visible for devlink
infrastructure, therefore APIs should not be used simultaneously.
IMPLEMENTATION DETAILS
Driver provide two level rate hierarchy to manage bandwidth - group
level and vport level. Initially each vport added to internal unlimited
group created by default. Each rate element (vport or group) receive
bandwidth relative to its parent element (for groups the parent is a
physical link itself) in a Round Robin manner, where element get
bandwidth value according to its weight. Example:
Created four rate groups with tx_share limits:
$ devlink port function rate add \
pci/0000:06:00.0/group_1 tx_share 30gbit
$ devlink port function rate add \
pci/0000:06:00.0/group_2 tx_share 20gbit
$ devlink port function rate add \
pci/0000:06:00.0/group_3 tx_share 20gbit
$ devlink port function rate add \
pci/0000:06:00.0/group_4 tx_share 10gbit
Weights created in HW for each group are relative to the bigest tx_share
value, which is 30gbit:
<group_1> 1.0
<group_2> 0.67
<group_3> 0.67
<group_4> 0.33
Assuming link speed is 50 Gbit/sec and each group can sustain such
amount of traffic, maximum bandwidth is 50 / (1.0 + 0.67 + 0.67 + 0.33)
= ~18.75 Gbit/sec. Normilized bandwidth values for groups:
<group_1> 18.75 * 1.0 = 18.75 Gbit/sec
<group_2> 18.75 * 0.67 = 12.5 Gbit/sec
<group_3> 18.75 * 0.67 = 12.5 Gbit/sec
<group_4> 18.75 * 0.33 = 6.25 Gbit/sec
If in example above group_1 doesn't produce any traffic, then maximum
bandwidth becomes 50 / (0.67 + 0.67 + 0.33) = ~30.0 Gbit/sec. Normalized
values:
<group_2> 30.0 * 0.67 = 20.0 Gbit/sec
<group_3> 30.0 * 0.67 = 20.0 Gbit/sec
<group_4> 30.0 * 0.33 = 10.0 Gbit/sec
Same normalization applied to each vport in the group.
Normalized values are internal, therefore driver provides QoS
tracepoints for next events:
* vport rate element creation/deletion:
* vport rate element configuration;
* group rate element creation/deletion;
* group rate element configuration.
PATCHES OVERVIEW
1 - Moving and isolation of eswitch QoS logic in separate file;
2 - Implement devlink leaf rate object support for vports;
3 - Implement rate groups creation/deletion;
4 - Implement TX rate management for the groups;
5 - Implement parent set for vports;
6 - Eswitch QoS tracepoints.

Turn BPF_PROG_RUN into a proper always inlined function. No functional and
performance changes are intended, but it makes it much easier to understand
what's going on with how BPF programs are actually get executed. It's more
obvious what types and callbacks are expected. Also extra () around input
parameters can be dropped, as well as `__` variable prefixes intended to avoid
naming collisions, which makes the code simpler to read and write.
This refactoring also highlighted one extra issue. BPF_PROG_RUN is both
a macro and an enum value (BPF_PROG_RUN == BPF_PROG_TEST_RUN). Turning
BPF_PROG_RUN into a function causes naming conflict compilation error. So
rename BPF_PROG_RUN into lower-case bpf_prog_run(), similar to
bpf_prog_run_xdp(), bpf_prog_run_pin_on_cpu(), etc. All existing callers of
BPF_PROG_RUN, the macro, are switched to bpf_prog_run() explicitly.

The msk can use backup subflows to transmit in-sequence data
only if there are no other active subflow. On active backup
scenario, the MPTCP connection can do forward progress only
due to MPTCP retransmissions - rtx can pick backup subflows.
This patch introduces a new flag flow MPTCP subflows: if the
underlying TCP connection made no progresses for long time,
and there are other less problematic subflows available, the
given subflow become stale.
Stale subflows are not considered active: if all non backup
subflows become stale, the MPTCP scheduler can pick backup
subflows for plain transmissions.
Stale subflows can return in active state, as soon as any reply
from the peer is observed.
Active backup scenarios can now leverage the available b/w
with no restrinction.

Netfilter fixes for net
The following patchset contains Netfilter fixes for net:
1) Restrict range element expansion in ipset to avoid soft lockup,
from Jozsef Kadlecsik.
2) Memleak in error path for nf_conntrack_bridge for IPv4 packets,
from Yajun Deng.
3) Simplify conntrack garbage collection strategy to avoid frequent
wake-ups, from Florian Westphal.
4) Fix NFNLA_HOOK_FUNCTION_NAME string, do not include module name.
5) Missing chain family netlink attribute in chain description
in nfnetlink_hook.
6) Incorrect sequence number on nfnetlink_hook dumps.
7) Use netlink request family in reply message for consistency.
8) Remove offload_pickup sysctl, use conntrack for established state
instead, from Florian Westphal.
9) Translate NFPROTO_INET/ingress to NFPROTO_NETDEV/ingress, since
NFPROTO_INET is not exposed through nfnetlink_hook.
* git://git.kernel.org/pub/scm/linux/kernel/git/pablo/nf:
netfilter: nfnetlink_hook: translate inet ingress to netdev
netfilter: conntrack: remove offload_pickup sysctl again
netfilter: nfnetlink_hook: Use same family as request message
netfilter: nfnetlink_hook: use the sequence number of the request message
netfilter: nfnetlink_hook: missing chain family

netfilter: conntrack: collect all entries in one cycle
netfilter: nf_conntrack_bridge: Fix memory leak when error
netfilter: ipset: Limit the maximal range of consecutive elements to add/delete

These two sysctls were added because the hardcoded defaults (2 minutes,
tcp, 30 seconds, udp) turned out to be too low for some setups.
They appeared in 5.14-rc1 so it should be fine to remove it again.
Marcelo convinced me that there should be no difference between a flow
that was offloaded vs. a flow that was not wrt. timeout handling.
Thus the default is changed to those for TCP established and UDP stream,
5 days and 120 seconds, respectively.
Marcelo also suggested to account for the timeout value used for the
offloading, this avoids increase beyond the value in the conntrack-sysctl
and will also instantly expire the conntrack entry with altered sysctls.
Example:
nf_conntrack_udp_timeout_stream=60
nf_flowtable_udp_timeout=60
This will remove offloaded udp flows after one minute, rather than two.
An earlier version of this patch also cleared the ASSURED bit to
allow nf_conntrack to evict the entry via early_drop (i.e., table full).
However, it looks like we can safely assume that connection timed out
via HW is still in established state, so this isn't needed.
Quoting Oz:
[..] the hardware sends all packets with a set FIN flags to sw.
[..] Connections that are aged in hardware are expected to be in the
established state.
In case it turns out that back-to-sw-path transition can occur for
'dodgy' connections too (e.g., one side disappeared while software-path
would have been in RETRANS timeout), we can adjust this later.

Add an option lacp_active, which is similar with team's runner.active.
This option specifies whether to send LACPDU frames periodically. If set
on, the LACPDU frames are sent along with the configured lacp_rate
setting. If set off, the LACPDU frames acts as "speak when spoken to".
Note, the LACPDU state frames still will be sent when init or unbind port.

All other user triggered operations are gone from ndo_ioctl, so move
the SIOCBOND family into a custom operation as well.
The .ndo_ioctl() helper is no longer called by the dev_ioctl.c code now,
but there are still a few definitions in obsolete wireless drivers as well
as the appletalk and ieee802154 layers to call SIOCSIFADDR/SIOCGIFADDR
helpers from inside the kernel.
