Currently, when the rule is not to be exclusively executed by the
hardware, extack is not passed along and offloading failures don't
get logged. The idea was that hardware failures are okay because the
rule will get executed in software then and this way it doesn't confuse
unware users.
But this is not helpful in case one needs to understand why a certain
rule failed to get offloaded. Considering it may have been a temporary
failure, like resources exceeded or so, reproducing it later and knowing
that it is triggering the same reason may be challenging.
The ultimate goal is to improve Open vSwitch debuggability when using
flower offloading.
This patch adds a new flag to enable verbose logging. With the flag set,
extack will be passed to the driver, which will be able to log the
error. As the operation itself probably won't fail (not because of this,
at least), current iproute will already log it as a Warning.
The flag is generic, so it can be reused later. No need to restrict it
just for HW offloading. The command line will follow the syntax that
tc-ebpf already uses, tc ... [ verbose ] ... , and extend its meaning.
For example:
# ./tc qdisc add dev p7p1 ingress
# ./tc filter add dev p7p1 parent ffff: protocol ip prio 1 \
flower verbose \
src_mac ed:13:db:00:00:00 dst_mac 01:80:c2:00:00:d0 \
src_ip 56.0.0.0 dst_ip 55.0.0.0 action drop
Warning: TC offload is disabled on net device.
# echo $?

The sequence of actions done by device drivers to append their device
specific hardware/firmware logs to /proc/vmcore are as follows:
1. During probe (before hardware is initialized), device drivers
register to the vmcore module (via vmcore_add_device_dump()), with
callback function, along with buffer size and log name needed for
firmware/hardware log collection.
2. vmcore module allocates the buffer with requested size. It adds
an Elf note and invokes the device driver's registered callback
function.
3. Device driver collects all hardware/firmware logs into the buffer
and returns control back to vmcore module.
Ensure that the device dump buffer size is always aligned to page size
so that it can be mmaped.
Also, rename alloc_elfnotes_buf() to vmcore_alloc_buf() to make it more
generic and reserve NT_VMCOREDD note type to indicate vmcore device
dump.

(1) Fix missing start of expect-Rx-by timeout on initial packet
transmission so that calls will time out if the peer doesn't respond.
(2) Fix error reception on AF_INET6 sockets by using the correct family of
sockopts on the UDP transport socket.
(3) Fix setting the minimum security level on kernel calls so that they
can be encrypted.
(4) Add a tracepoint to log ICMP/ICMP6 and other error reports from the
transport socket.
(5) Add a tracepoint to log UDP sendmsg failure so that we can find out if
transmission failure occurred on the UDP socket.

Add support for PHYLINK within the DSA subsystem in order to support more
complex devices such as pluggable (SFP) and non-pluggable (SFF) modules, 10G
PHYs, and traditional PHYs. Using PHYLINK allows us to drop some amount of
complexity we had while probing fixed and non-fixed PHYs using Device Tree.
Because PHYLINK separates the Ethernet MAC/port configuration into different
stages, we let switch drivers implement those, and for now, we maintain
functionality by calling dsa_slave_adjust_link() during
phylink_mac_link_{up,down} which provides semantically equivalent steps.
Drivers willing to take advantage of PHYLINK should implement the phylink_mac_*
operations that DSA wraps.
We cannot quite remove the adjust_link() callback just yet, because a number of
drivers rely on that for configuring their "CPU" and "DSA" ports, this is done
dsa_port_setup_phy_of() and dsa_port_fixed_link_register_of() still.
Drivers that utilize fixed links for user-facing ports (e.g: bcm_sf2) will need
to implement phylink_mac_ops from now on to preserve functionality, since PHYLINK
*does not* create a phy_device instance for fixed links.

In preparation for adding support for PHYLINK within DSA, define a number of
operations that we will need and that switch drivers can start implementing.
Proper integration with PHYLINK will follow in subsequent patches.
We start selecting PHYLINK (which implies PHYLIB) in net/dsa/Kconfig
such that drivers can be guaranteed that this dependency is properly
taken care of and can start referencing PHYLINK helper functions without
requiring stubs or anything.

There was a regression at some point from the intended functionality of
commit f60c3704e8 ("bonding: Fix alb mode to only use first level
vlans.")
Given the return value vlan_get_encap_level() we need to store the nest
level of the bond device, and then compare the vlan's encap level to
this. Without this, this check always fails and learning packets are
never sent.
In addition, this same commit caused a regression in the behavior of
balance_alb, which requires learning packets be sent for all interfaces
using the slave's mac in order to load balance properly. For vlan's
that have not set a user mac, we can send after checking one bit.
Otherwise we need send the set mac, albeit defeating rx load balancing
for that vlan.

This version has some suggestions by Eric Dumazet:
- Use a local variable for the mark in IPv6 instead of ctl_sk to avoid SMP
races.
- Use the more elegant "IP4_REPLY_MARK(net, skb->mark) ?: sk->sk_mark"
statement.
- Factorize code as sk_fullsock() check is not necessary.
Aidan McGurn from Openwave Mobility systems reported the following bug:
"Marked routing is broken on customer deployment. Its effects are large
increase in Uplink retransmissions caused by the client never receiving
the final ACK to their FINACK - this ACK misses the mark and routes out
of the incorrect route."
Currently marks are added to sk_buffs for replies when the "fwmark_reflect"
sysctl is enabled. But not for TW sockets that had sk->sk_mark set via
setsockopt(SO_MARK..).
Fix this in IPv4/v6 by adding tw->tw_mark for TIME_WAIT sockets. Copy the the
original sk->sk_mark in __inet_twsk_hashdance() to the new tw->tw_mark location.
Then progate this so that the skb gets sent with the correct mark. Do the same
for resets. Give the "fwmark_reflect" sysctl precedence over sk->sk_mark so that
netfilter rules are still honored.

This patch is meant to allow us to avoid having to recompute the checksum
from scratch and have it passed as a parameter.
Instead of taking that approach we can take advantage of the fact that the
length that was used to compute the existing checksum is included in the
UDP header.
Finally to avoid the need to invert the result we can just call csum16_add
and csum16_sub directly. By doing this we can avoid a number of
instructions in the loop that is handling segmentation.

When the core networking needs to detect the transport offset in a given
packet and parse it explicitly, a full-blown flow_keys struct is used for
storage.
This patch introduces a smaller keys store, rework the basic flow dissect
helper to use it, and apply this new helper where possible - namely in
skb_probe_transport_header(). The used flow dissector data structures
are renamed to match more closely the new role.
The above gives ~50% performance improvement in micro benchmarking around
skb_probe_transport_header() and ~30% around eth_get_headlen(), mostly due
to the smaller memset. Small, but measurable improvement is measured also
in macro benchmarking.
v1 -> v2: use the new helper in eth_get_headlen() and skb_get_poff(),
as per DaveM suggestion

`mf_mode' field indicates the multi-partitioning mode the device is
configured to. This method doesn't scale very well, adding a new MF mode
requires going over all the existing conditions, and deciding whether those
are needed for the new mode or not.
The patch defines a set of bit-fields for modes which are derived according
to the mode info shared by the MFW and all the configuration would be made
according to those. To add a new mode, there would be a single place where
we'll need to go and choose which bits apply and which don't.

IPCTNL_MSG_CT_GET_STATS netlink command allow to monitor current number
of conntrack entries. However, if one wants to compare it with the
maximum (and detect exhaustion), the only solution is currently to read
sysctl value.
This patch add nf_conntrack_max value in netlink message, and simplify
monitoring for application built on netlink API.

IPv6 Segment Routing Header (SRH) contains a list of SIDs to be crossed
by SR encapsulated packet. Each SID is encoded as an IPv6 prefix.
When a Firewall receives an SR encapsulated packet, it should be able
to identify which node previously processed the packet (previous SID),
which node is going to process the packet next (next SID), and which
node is the last to process the packet (last SID) which represent the
final destination of the packet in case of inline SR mode.
An example use-case of using these features could be SID list that
includes two firewalls. When the second firewall receives a packet,
it can check whether the packet has been processed by the first firewall
or not. Based on that check, it decides to apply all rules, apply just
subset of the rules, or totally skip all rules and forward the packet to
the next SID.
This patch extends SRH match to support matching previous SID, next SID,
and last SID.

This patch includes a new attribute in the numgen structure to allow
the lookup of an element based on the number generator as a key.
For this purpose, different ops have been included to extend the
current numgen inc functions.
Currently, only supported for numgen incremental operations, but
it will be supported for random in a follow-up patch.

Pull rdma fixes from Doug Ledford:
"This is our first pull request of the rc cycle. It's not that it's
been overly quiet, we were just waiting on a few things before sending
this off.
For instance, the 6 patch series from Intel for the hfi1 driver had
actually been pulled in on Tuesday for a Wednesday pull request, only
to have Jason notice something I missed, so we held off for some
testing, and then on Thursday had to respin the series because the
very first patch needed a minor fix (unnecessary cast is all).
There is a sizable hns patch series in here, as well as a reasonably
largish hfi1 patch series, then all of the lines of uapi updates are
just the change to the new official Linux-OpenIB SPDX tag (a bunch of
our files had what amounts to a BSD-2-Clause + MIT Warranty statement
as their license as a result of the initial code submission years ago,
and the SPDX folks decided it was unique enough to warrant a unique
tag), then the typical mlx4 and mlx5 updates, and finally some cxgb4
and core/cache/cma updates to round out the bunch.
None of it was overly large by itself, but in the 2 1/2 weeks we've
been collecting patches, it has added up :-/.
As best I can tell, it's been through 0day (I got a notice about my
last for-next push, but not for my for-rc push, but Jason seems to
think that failure messages are prioritized and success messages not
so much). It's also been through linux-next. And yes, we did notice in
the context portion of the CMA query gid fix patch that there is a
dubious BUG_ON() in the code, and have plans to audit our BUG_ON usage
and remove it anywhere we can.
