Intel Wired LAN Driver Updates 2021-07-23

This series contains updates to i40e driver only.

Arkadiusz corrects the order of calls for disabling queues to resolve
a false error message and adds a better message to the user when
transitioning FW LLDP back on while the firmware is still processing
the off request.

Lukasz adds additional information regarding possible incorrect cable
use when a PHY type error occurs.

Jedrzej adds ndo_select_queue support to resolve incorrect queue
selection when SW DCB is used and adds a warning when there are not
enough queues for desired TC configuration.

Merge tag 'mac80211-for-net-2021-07-23' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211

Couple of fixes:
 * fix aggregation on mesh
 * fix late enabling of 4-addr mode
 * leave monitor SKBs with some headroom
 * limit band information for old applications
 * fix virt-wifi WARN_ON
 * fix memory leak in cfg80211 BSS list maintenance

Commit 7930742d, reverting 26fd962b, missed out on reverting an incorrect
change to a return value.  The niu_pci_vpd_scan_props(..) == 1 case appears
to be a normal path - treating it as an error and return -EINVAL was
breaking VPD_SCAN and causing the driver to fail to load.

Fix, so my Neptune card works again.

Syzbot reported memory leak in qrtr. The problem was in unputted
struct sock. qrtr_local_enqueue() function calls qrtr_port_lookup()
which takes sock reference if port was found. Then there is the following
check:

if (!ipc || &ipc->sk == skb->sk) {
	...
	return -ENODEV;
}

Since we should drop the reference before returning from this function and
ipc can be non-NULL inside this if, we should add qrtr_port_put() inside
this if.

The similar corner case is in qrtr_endpoint_post() as Manivannan
reported. In case of sock_queue_rcv_skb() failure we need to put
port reference to avoid leaking struct sock pointer.

A wwan link created via the wwan_create_default_link procedure is
never notified to the user (RTM_NEWLINK), causing issues with user
tools relying on such event to track network links (NetworkManager).

This is because the procedure misses a call to rtnl_configure_link(),
which sets the link as initialized and notifies the new link (cf
proper usage in __rtnl_newlink()).

In cases where the header straight after the tunnel header was
another ethernet header (TEB), instead of the network header,
the ECN decapsulation code would treat the ethernet header as if
it was an IP header, resulting in mishandling and possible
wrong drops or corruption of the IP header.

In this case, ECT(1) is sent, so IP_ECN_decapsulate tries to copy it to the
inner IPv4 header, and correct its checksum.

The offset of the ECT bits in an IPv4 header corresponds to the
lower 2 bits of the second octet of the destination MAC address
in the ethernet header.
The IPv4 checksum corresponds to end of the source address.

In order to reproduce:

    $ ip netns add A
    $ ip netns add B
    $ ip -n A link add _v0 type veth peer name _v1 netns B
    $ ip -n A link set _v0 up
    $ ip -n A addr add dev _v0 10.254.3.1/24
    $ ip -n A route add default dev _v0 scope global
    $ ip -n B link set _v1 up
    $ ip -n B addr add dev _v1 10.254.1.6/24
    $ ip -n B route add default dev _v1 scope global
    $ ip -n B link add gre1 type gretap local 10.254.1.6 remote 10.254.3.1 key 0x49000000
    $ ip -n B link set gre1 up

    # Now send an IPv4/GRE/Eth/IPv4 frame where the outer header has ECT(1),
    # and the inner header has no ECT bits set:

    $ cat send_pkt.py
        #!/usr/bin/env python3
        from scapy.all import *

        pkt = IP(b'E\x01\x00\xa7\x00\x00\x00\x00@/`%\n\xfe\x03\x01\n\xfe\x01\x06 \x00eXI\x00'

In the original packet, the source/destinatio MAC addresses are

In the received packet, they are

For implicit-connect, when it's either SYN- or SYN+, an ACK should
be sent back to the client immediately. It's not appropriate for
the client to enter established state only after receiving data
from the server.

On client side, after the SYN is sent out, tipc_wait_for_connect()
should be called to wait for the ACK if timeout is set.

This patch also restricts __tipc_sendstream() to call __sendmsg()
only when it's in TIPC_OPEN state, so that the client can program
in a single loop doing both connecting and data sending like:

  for (...)
      sendmsg(dest, buf);

This makes the implicit-connect more implicit.

In SW DCB mode the packets sent receive incorrect UP tags. They are

When a monitor interface is present together with other interfaces, a
received skb is copied and received on the monitor netdev. Before, the
copied skb was allocated with exactly the amount of space needed for
the radiotap header, resulting in an skb without any headroom at all
being received on the monitor netdev. With the introduction of eBPF
and XDP in the kernel, skbs may be processed by custom eBPF programs.
However, since the skb cannot be reallocated in the eBPF program, no
more data or headers can be pushed. The old code made sure the final
headroom was zero regardless of the value of NET_SKB_PAD, so increasing
that constant would have no effect.

Now we allocate monitor skb copies with a headroom of NET_SKB_PAD bytes
before the radiotap header. Monitor interfaces now behave in the same
way as other netdev interfaces that honor the NET_SKB_PAD constant.

  revert so as not to regress PPC 8xx in terms of functionality.

Any interraction with the buffer pool (seeding a buffer, acquire one) is
made through a software portal (SWP, a DPIO object).
There are circumstances where the dpaa2-switch driver probes on a DPSW
before any DPIO devices have been probed. In this case, seeding of the
buffer pool will lead to a panic since no SWPs are initialized.

To fix this, seed the buffer pool after making sure that the software
portals have been probed and are ready to be used.

====================
Fixes for KSZ DSA switch

These patches fix issues I encountered while using a KSZ9897 as a DSA
switch with a broadcom GENET network device as the DSA master device.

PATCH 1 fixes an invalid access to an SKB in case it is scattered.
PATCH 2 fixes incorrect hardware checksum calculation caused by the DSA
tag.

Changes in v2:
- instead of linearizing the SKBs only for KSZ switches ensure linearized
  SKBs for all tail taggers by clearing the feature flags NETIF_F_HW_SG and
  NETIF_F_FRAGLIST (suggested by Vladimir Oltean)

The patches have been tested with a KSZ9897 and apply against net-next.

If the checksum calculation is offloaded to the network device (e.g due to
NETIF_F_HW_CSUM inherited from the DSA master device), the calculated
layer 4 checksum is incorrect. This is since the DSA tag which is placed
after the layer 4 data is considered as being part of the daa and thus
errorneously included into the checksum calculation.
To avoid this, always calculate the layer 4 checksum in software.

The function skb_put() that is used by tail taggers to make room for the
DSA tag must only be called for linearized SKBS. However in case that the
slave device inherited features like NETIF_F_HW_SG or NETIF_F_FRAGLIST the
SKB passed to the slaves transmit function may not be linearized.
Avoid those SKBs by clearing the NETIF_F_HW_SG and NETIF_F_FRAGLIST flags
for tail taggers.
Furthermore since the tagging protocol can be changed at runtime move the
code for setting up the slaves features into dsa_slave_setup_tagger().
