virtio/vsock: some updates for MSG_PEEK flag
This patchset does several things around MSG_PEEK flag support. In
general words it reworks MSG_PEEK test and adds support for this flag
in SOCK_SEQPACKET logic. Here is per-patch description:
1) This is cosmetic change for SOCK_STREAM implementation of MSG_PEEK:
1) I think there is no need of "safe" mode walk here as there is no
"unlink" of skbs inside loop (it is MSG_PEEK mode - we don't change
queue).
2) Nested while loop is removed: in case of MSG_PEEK we just walk
over skbs and copy data from each one. I guess this nested loop
even didn't behave as loop - it always executed just for single
iteration.
2) This adds MSG_PEEK support for SOCK_SEQPACKET. It could be implemented
be reworking MSG_PEEK callback for SOCK_STREAM to support SOCK_SEQPACKET
also, but I think it will be more simple and clear from potential
bugs to implemented it as separate function thus not mixing logics
for both types of socket. So I've added it as dedicated function.
3) This is reworked MSG_PEEK test for SOCK_STREAM. Previous version just
sent single byte, then tried to read it with MSG_PEEK flag, then read
it in normal way. New version is more complex: now sender uses buffer
instead of single byte and this buffer is initialized with random
values. Receiver tests several things:
1) Read empty socket with MSG_PEEK flag.
2) Read part of buffer with MSG_PEEK flag.
3) Read whole buffer with MSG_PEEK flag, then checks that it is same
as buffer from 2) (limited by size of buffer from 2) of course).
4) Read whole buffer without any flags, then checks that it is same
as buffer from 3).
4) This is MSG_PEEK test for SOCK_SEQPACKET. It works in the same way
as for SOCK_STREAM, except it also checks combination of MSG_TRUNC
and MSG_PEEK.

This reworks current implementation of MSG_PEEK logic:
1) Replaces 'skb_queue_walk_safe()' with 'skb_queue_walk()'. There is
no need in the first one, as there are no removes of skb in loop.
2) Removes nested while loop - MSG_PEEK logic could be implemented
without it: just iterate over skbs without removing it and copy
data from each until destination buffer is not full.

====================
net: ethernet: mtk_eth_soc: add basic support for MT7988 SoC
The MediaTek MT7988 SoC introduces a new version (3) of the NETSYS
block and comes with three instead of two MACs.
The first MAC can be internally connected to a built-in Gigabit
Ethernet switch with four 1000M/100M/10M twisted pair user ports.
The second MAC can be internally connected to a built-in 2500Base-T
Ethernet PHY.
There are two SerDes units which can be operated in USXGMII, 10GBase-(K)R,
5GBase-R, 2500Base-X, 1000Base-X or SGMII interface mode.
This series adds initial support for NETSYS v3 and the first MAC of the
MT7988 SoC connecting the built-in DSA switch.
The switch is supported since commit 110c18bfed414 ("net: dsa: mt7530:
introduce driver for MT7988 built-in switch").
Basic support for the 1000M/100M/10M built-in PHYs connected to the
switch ports is present since commit ("98c485eaf509b net: phy: add
driver for MediaTek SoC built-in GE PHYs").

MCAM register reports the device supported management features. Querying
this register exposes if features are supported with the current
firmware version in the current ASIC. Then, the driver can separate
between different implementations dynamically.
MCAM register supports querying whether the MCIA register supports 128
bytes payloads or only 48 bytes. Add support for the register as
preparation for allowing larger MCIA transactions.
Note that the access to the bits in the field 'mng_feature_cap_mask' is
not same to other mask fields in other registers. In most of the cases
bit #0 is the first one in the last dword, in MCAM register, bits #0-#31
are in the first dword and so on. Declare the mask field using bits
arrays per dword to simplify the access.

====================
ice: switchdev bridge offload
Wojciech Drewek says:
Linux bridge provides ability to learn MAC addresses and vlans
detected on bridge's ports. As a result of this, FDB (forward data base)
entries are created and they can be offloaded to the HW. By adding
VF's port representors to the bridge together with the uplink netdev,
we can learn VF's and link partner's MAC addresses. This is achieved
by slow/exception-path, where packets that do not match any filters
(FDB entries in this case) are send to the bridge ports.
Driver keeps track of the netdevs added to the bridge
by listening for NETDEV_CHANGEUPPER event. We distinguish two types
of bridge ports: uplink port and VF's representor port. Linux
bridge always learns src MAC of the packet on rx path. With the
current slow-path implementation, it means that we will learn
VF's MAC on port repr (when the VF transmits the packet) and
link partner's MAC on uplink (when we receive it on uplink from LAN).
The driver is notified about learning of the MAC/VLAN by
SWITCHDEV_FDB_{ADD|DEL}_TO_DEVICE events. This is followed by creation
of the HW filter. The direction of the filter is based on port
type (uplink or VF repr). In case of the uplink, rule forwards
the packets to the LAN (matching on link partner's MAC). When the
notification is received on VF repr then the rule forwards the
packets to the associated VF (matching on VF's MAC).
This approach would not work on its own however. This is because if
one of the directions is offloaded, then the bridge would not be able
to learn the other one. If the egress rule is added (learned on uplink)
then the response from the VF will be sent directly to the LAN.
The packet will not got through slow-path, it would not be seen on
VF's port repr. Because of that, the bridge would not learn VF's MAC.
This is solved by introducing guard rule. It prevents forward rule from
working until the opposite direction is offloaded.
Aging is not fully supported yet, aging time is static for now. The
follow up submissions will introduce counters that will allow us to
keep track if the rule is actually being used or not.
A few fixes/changes are needed for this feature to work with ice driver.
These are introduced in first 5 patches.

The IEEE1588 Standard specifies that the timestamps of Packets must be
captured when the PTP message timestamp point (leading edge of first
octet after the start of frame delimiter) crosses the boundary between
the node and the network. As the MAC latches the timestamp at an
internal point, the captured timestamp must be corrected for the
additional path latency, as described in the publicly available
datasheet [1].
This patch only corrects for the MAC-Internal delay, which can be read
out from the MAC_Ingress_Timestamp_Latency register, since the Phy
framework currently does not support querying the Phy ingress and egress
latency. The Closs Domain Crossing Circuits errors as indicated in [1]
are already being accounted in the stmmac_get_tx_hwtstamp() function and
are not corrected here.
As the Latency varies for different link speeds and MII
modes of operation, the correction value needs to be updated on each
link state change.
As the delay also causes a phase shift in the timestamp counter compared
to the rest of the network, this correction will also reduce phase error
when generating PPS outputs from the timestamp counter.

The last s390 machine that supported FDDI was z900 ('7th generation',
released in 2000). The oldest machine generation currently supported by
the Linux kernel is MARCH_Z10 (released 2008). If there is still a usecase
for connecting a Linux on s390 instance to a LAN Channel Station (LCS), it
can only do so via Ethernet.
Randy Dunlap[1] found that LCS over FDDI has never worked, when FDDI
was compiled as module. Instead of fixing that, remove the FDDI option
from the lcs driver.
While at it, make the CONFIG_LCS description a bit more helpful.

There are currently two paths that call remove_xps_queue():
1. __netif_set_xps_queue -> remove_xps_queue
2. clean_xps_maps -> remove_xps_queue_cpu -> remove_xps_queue
There is no need to check dev_maps in remove_xps_queue() because
dev_maps has been checked on these two paths.

Support UDP encapsulation in packet offload mode
As was raised by Ilia in this thread [1], the ESP over UDP feature is
supported in packet offload mode. So comes this series, which adds
relevant bits to the mlx5 driver and opens XFRM core code to accept
such configuration.
NAT-T is part of IKEv2 and strongswan uses it automatically [2].

====================
Remove legacy phylink behaviour
This series removes the - as far as I can tell - unreachable code in
mtk_eth_soc that relies upon legacy phylink behaviour, and then removes
the support in phylink for this legacy behaviour.
Patch 1 removes the clocking configuration from mtk_eth_soc for non-
TRGMII, non-serdes based interface modes, and disables those interface
modes prior to phylink configuration.
Patch 2 removes the mac_pcs_get_state() method from mtk_eth_soc which
I believe is also not used - mtk_eth_soc appears not to be used with
SFPs (which would use a kind of in-band mode) nor does any DT appear
to specify in-band mode for any non-serdes based interface mode.
With both of those dealt with, the kernel is now free of any driver
relying on the phylink legacy mode. Therefore, patch 3 removes support
for this.
Finally, with the advent of a new driver being submitted today that
makes use of state->speed in the mac_config() path, patch 4 ensures that
any phylink_link_state member that should not be used in mac_config is
either cleared or set to an invalid value.

Remove the .mac_pcs_get_state function, since as far as I can tell is
never called - no DT appears to specify an in-band-status management
nor SFP support for this driver.
Removal of this, along with the previous patch to remove the incorrect
clocking configuration, means that the driver becomes non-legacy, so
we can remove the "legacy_pre_march2020" status from this driver.

MT7623 GMAC0 attempts to configure the system clocking according to the
required speed in the .mac_config callback for non-SGMII, non-baseX and
non-TRGMII modes.
state->speed setting has never been reliable in the .mac_config
callback - there are cases where this is not the link speed,
particularly via ethtool paths, so this has always been unreliable (as
detailed in phylink's documentation.)
There is the additional issue that mtk_gmac0_rgmii_adjust() will only
be called if state->interface changes, which means it only configures
the system clocking on the very first .mac_config call, which will be
made when the network device is first brought up before any link is
established.
Essentially, this code is incredibly buggy, and probably never worked.
Moreover, checking the in-kernel DT files, it seems no platform makes
use of this code path.
Therefore, let's remove it, and disable interface modes for port 0 that
are not SGMII, 1000base-X, 2500base-X or TRGMII on the MT7623.

The MPTCP code uses the assumption that the tcp_win_from_space() helper
does not use any TCP-specific field, and thus works correctly operating
on an MPTCP socket.
The commit dfa2f0483360 ("tcp: get rid of sysctl_tcp_adv_win_scale")
broke such assumption, and as a consequence most MPTCP connections stall
on zero-window event due to auto-tuning changing the rcv buffer size
quite randomly.
Address the issue syncing again the MPTCP auto-tuning code with the TCP
one. To achieve that, factor out the windows size logic in socket
independent helpers, and reuse them in mptcp_rcv_space_adjust(). The
MPTCP level scaling_ratio is selected as the minimum one from the all
the subflows, as a worst-case estimate.

Replace kstrtoint() by kstrtobool() in the sysfs _store() functions.
This improves the user usability and simplify the code.
With this fix, it is now possible to use [YyNn] to set and unset a
feature. Old behaviour is still unchanged.
kstrtobool() is also safer and doesn't need the extra validation that
is required when converting a string to bool (end field in the struct),
which makes the code simpler.
