====================
net: ethernet: ti: cpsw: Add XDP support
This patchset adds XDP support for TI cpsw driver and base it on
page_pool allocator. It was verified on af_xdp socket drop,
af_xdp l2f, ebpf XDP_DROP, XDP_REDIRECT, XDP_PASS, XDP_TX.
It was verified with following configs enabled:
CONFIG_JIT=y
CONFIG_BPFILTER=y

Also regular tests with iperf2 were done in order to verify impact on
regular netstack performance, compared with base commit:
https://pastebin.com/JSMT0iZ4
v8..v9:
- fix warnings on arm64 caused by typos in type casting
v7..v8:
- corrected dma calculation based on headroom instead of hard start
- minor comment changes
v6..v7:
- rolled back to v4 solution but with small modification
- picked up patch:
https://www.spinics.net/lists/netdev/msg583145.html
- added changes related to netsec fix and cpsw
v5..v6:
- do changes that is rx_dev while redirect/flush cycle is kept the same
- dropped net: ethernet: ti: davinci_cpdma: return handler status
- other changes desc in patches
v4..v5:
- added two plreliminary patches:
net: ethernet: ti: davinci_cpdma: allow desc split while down
net: ethernet: ti: cpsw_ethtool: allow res split while down
- added xdp alocator refcnt on xdp level, avoiding page pool refcnt
- moved flush status as separate argument for cpdma_chan_process
- reworked cpsw code according to last changes to allocator
- added missed statistic counter
v3..v4:
- added page pool user counter
- use same pool for ndevs in dual mac
- restructured page pool create/destroy according to the last changes in API
v2..v3:
- each rxq and ndev has its own page pool
v1..v2:
- combined xdp_xmit functions
- used page allocation w/o refcnt juggle
- unmapped page for skb netstack
- moved rxq/page pool allocation to open/close pair
- added several preliminary patches:
net: page_pool: add helper function to retrieve dma addresses

net: ethernet: ti: cpsw: add XDP support
Add XDP support based on rx page_pool allocator, one frame per page.
Page pool allocator is used with assumption that only one rx_handler
is running simultaneously. DMA map/unmap is reused from page pool
despite there is no need to map whole page.
Due to specific of cpsw, the same TX/RX handler can be used by 2
network devices, so special fields in buffer are added to identify
an interface the frame is destined to. Thus XDP works for both
interfaces, that allows to test xdp redirect between two interfaces
easily. Also, each rx queue have own page pools, but common for both
netdevs.
XDP prog is common for all channels till appropriate changes are added
in XDP infrastructure. Also, once page_pool recycling becomes part of
skb netstack some simplifications can be added, like removing
page_pool_release_page() before skb receive.
In order to keep rx_dev while redirect, that can be somehow used in
future, do flush in rx_handler, that allows to keep rx dev the same
while redirect. It allows to conform with tracing rx_dev pointed
by Jesper.
Also, there is probability, that XDP generic code can be extended to
support multi ndev drivers like this one, using same rx queue for
several ndevs, based on switchdev for instance or else. In this case,
driver can be modified like exposed here:

net: core: page_pool: add user refcnt and reintroduce page_pool_destroy
Jesper recently removed page_pool_destroy() (from driver invocation)
and moved shutdown and free of page_pool into xdp_rxq_info_unreg(),
in-order to handle in-flight packets/pages. This created an asymmetry
in drivers create/destroy pairs.
This patch reintroduce page_pool_destroy and add page_pool user
refcnt. This serves the purpose to simplify drivers error handling as
driver now drivers always calls page_pool_destroy() and don't need to
track if xdp_rxq_info_reg_mem_model() was unsuccessful.
This could be used for a special cases where a single RX-queue (with a
single page_pool) provides packets for two net_device'es, and thus
needs to register the same page_pool twice with two xdp_rxq_info
structures.
This patch is primarily to ease API usage for drivers. The recently
merged netsec driver, actually have a bug in this area, which is
solved by this API change.
This patch is a modified version of Ivan Khoronzhuk's original patch.

Like any IPv6 capable device, 6LNs can have multiple addresses assigned

After checking the destination address against all peers link-local

RFC7668 defines the scope of Neighbor Advertisements in Section 3.2.3:
1. "A Bluetooth LE 6LN MUST NOT register its link-local address"
2. "A Bluetooth LE 6LN MUST register its non-link-local addresses with
the 6LBR by sending Neighbor Solicitation (NS) messages ..."
Due to these constranits both the link-local addresses tracked in the

Bluetooth: validate BLE connection interval updates
Problem: The Linux Bluetooth stack yields complete control over the BLE
connection interval to the remote device.
The Linux Bluetooth stack provides access to the BLE connection interval
min and max values through /sys/kernel/debug/bluetooth/hci0/
conn_min_interval and /sys/kernel/debug/bluetooth/hci0/conn_max_interval.
These values are used for initial BLE connections, but the remote device
has the ability to request a connection parameter update. In the event
that the remote side requests to change the connection interval, the Linux
kernel currently only validates that the desired value is within the
acceptable range in the Bluetooth specification (6 - 3200, corresponding to
7.5ms - 4000ms). There is currently no validation that the desired value
requested by the remote device is within the min/max limits specified in
the conn_min_interval/conn_max_interval configurations. This essentially
leads to Linux yielding complete control over the connection interval to
the remote device.
The proposed patch adds a verification step to the connection parameter
update mechanism, ensuring that the desired value is within the min/max
bounds of the current connection. If the desired value is outside of the
current connection min/max values, then the connection parameter update
request is rejected and the negative response is returned to the remote
device. Recall that the initial connection is established using the local
conn_min_interval/conn_max_interval values, so this allows the Linux
administrator to retain control over the BLE connection interval.
The one downside that I see is that the current default Linux values for
conn_min_interval and conn_max_interval typically correspond to 30ms and
50ms respectively. If this change were accepted, then it is feasible that
some devices would no longer be able to negotiate to their desired
connection interval values. This might be remedied by setting the default
Linux conn_min_interval and conn_max_interval values to the widest
supported range (6 - 3200 / 7.5ms - 4000ms). This could lead to the same
behavior as the current implementation, where the remote device could
request to change the connection interval value to any value that is
permitted by the Bluetooth specification, and Linux would accept the
desired value.

Bluetooth: Check state in l2cap_disconnect_rsp
Because of both sides doing L2CAP disconnection at the same time, it
was possible to receive L2CAP Disconnection Response with CID that was
already freed. That caused problems if CID was already reused and L2CAP
Connection Request with same CID was sent out. Before this patch kernel
deleted channel context regardless of the state of the channel.
Example where leftover Disconnection Response (frame #402) causes local
device to delete L2CAP channel which was not yet connected. This in
turn confuses remote device's stack because same CID is re-used without
properly disconnecting.

For the Marvell HCI UART we have to upload two firmware files. The first

This is caused by a vendor event that corresponds to an earlier command
to change the baudrate. The event is not processed in the context of the
baudrate change and is later interpreted as response to the firmware
download command (which is also a vendor command), but the driver detects
that the event doesn't have the expected amount of associated data.
More details:
For the WCN3990 the vendor command for a baudrate change isn't sent as
synchronous HCI command, because the controller sends the corresponding
vendor event with the new baudrate. The event is received and decoded
after the baudrate change of the host port.
Identify the 'unused' event when it is received and don't add it to

====================
mlx5 TLS TX HW offload support
This series from Eran and me, adds TLS TX HW offload support to
the mlx5 driver.
This offloads the kTLS encryption process from kernel to the
Mellanox NIC, saving CPU cycles and improving utilization.
Upon a new TLS connection request, driver is responsible to create
a dedicated HW context and configure it according to the crypto info,
so HW can do the encryption itself.
When the HW context gets out-of-sync (i.e. due to packets retransmission),
driver is responsible for the re-sync process.
This is done by posting special resync descriptors to the HW.
Feature is supported on Mellanox Connect-X 6DX, and newer.
Series was tested on SimX simulator.
Series generated against net-next commit [1], with Saeed's request pulled [2]:

- Maintain static and progress HW contexts by posting the proper

- Use a special DUMP opcode to replay the previous frags and sync

====================
mlxsw: Enable/disable PTP shapers
Shalom says:
In order to get more accurate hardware time stamping in Spectrum-1, the
driver needs to apply a shaper on the port for speeds lower than 40Gbps.
This shaper is called a PTP shaper and it is applied on hierarchy 0,
which is the port hierarchy. This shaper may affect the shaper rates of
all hierarchies.
This patchset adds the ability to enable or disable the PTP shaper on
the port in two scenarios:
1. When the user wants to enable/disable the hardware time stamping
2. When the port is brought up or down (including port speed change)
Patch #1 adds the QEEC.ptps field that is used for enabling or disabling
the PTP shaper on a port.
Patch #2 adds a note about disabling the PTP shaper when calling to
mlxsw_sp_port_ets_maxrate_set().
Patch #3 adds the QPSC register that is responsible for configuring the
PTP shaper parameters per speed.
Patch #4 sets the PTP shaper parameters during the ptp_init().
Patch #5 adds new operation for getting the port's speed.
Patch #6 enables/disables the PTP shaper when turning on or off the
hardware time stamping.
Patch #7 enables/disables the PTP shaper when the port's status has
changed (including port speed change).
Patch #8 applies the PTP shaper enable/disable logic by filling the PTP
shaper parameters array.
