memory: tegra: Unify struct tegra_mc across SoC generations
As another step towards unifying both the Tegra210 (and earlier) and Tegra186 (and later) memory controller drivers, unify the structures that are used to represent them. Note that this comes at a slight space penalty since some fields are not used on all generations, but the benefits of unifying the driver outweigh the downsides.

memory: tegra: Consolidate register fields
Subsequent patches will add more register fields to the tegra_mc_client structure, so consolidate all register field definitions into a common sub-structure for coherency.

Networking changes for 5.13.
Core:
- bpf:
- allow bpf programs calling kernel functions (initially to
reuse TCP congestion control implementations)
- enable task local storage for tracing programs - remove the
need to store per-task state in hash maps, and allow tracing
programs access to task local storage previously added for
BPF_LSM
- add bpf_for_each_map_elem() helper, allowing programs to
walk all map elements in a more robust and easier to verify
fashion
- sockmap: support UDP and cross-protocol BPF_SK_SKB_VERDICT
redirection
- lpm: add support for batched ops in LPM trie
- add BTF_KIND_FLOAT support - mostly to allow use of BTF
on s390 which has floats in its headers files
- improve BPF syscall documentation and extend the use of kdoc
parsing scripts we already employ for bpf-helpers
- libbpf, bpftool: support static linking of BPF ELF files
- improve support for encapsulation of L2 packets
- xdp: restructure redirect actions to avoid a runtime lookup,
improving performance by 4-8% in microbenchmarks
- xsk: build skb by page (aka generic zerocopy xmit) - improve
performance of software AF_XDP path by 33% for devices
which don't need headers in the linear skb part (e.g. virtio)
- nexthop: resilient next-hop groups - improve path stability
on next-hops group changes (incl. offload for mlxsw)
- ipv6: segment routing: add support for IPv4 decapsulation
- icmp: add support for RFC 8335 extended PROBE messages
- inet: use bigger hash table for IP ID generation
- tcp: deal better with delayed TX completions - make sure we don't
give up on fast TCP retransmissions only because driver is
slow in reporting that it completed transmitting the original
- tcp: reorder tcp_congestion_ops for better cache locality
- mptcp:
- add sockopt support for common TCP options
- add support for common TCP msg flags
- include multiple address ids in RM_ADDR
- add reset option support for resetting one subflow
- udp: GRO L4 improvements - improve 'forward' / 'frag_list'
co-existence with UDP tunnel GRO, allowing the first to take
place correctly even for encapsulated UDP traffic
- micro-optimize dev_gro_receive() and flow dissection, avoid
retpoline overhead on VLAN and TEB GRO
- use less memory for sysctls, add a new sysctl type, to allow using
u8 instead of "int" and "long" and shrink networking sysctls
- veth: allow GRO without XDP - this allows aggregating UDP
packets before handing them off to routing, bridge, OvS, etc.
- allow specifing ifindex when device is moved to another namespace
- netfilter:
- nft_socket: add support for cgroupsv2
- nftables: add catch-all set element - special element used
to define a default action in case normal lookup missed
- use net_generic infra in many modules to avoid allocating
per-ns memory unnecessarily
- xps: improve the xps handling to avoid potential out-of-bound
accesses and use-after-free when XPS change race with other
re-configuration under traffic
- add a config knob to turn off per-cpu netdev refcnt to catch
underflows in testing
Device APIs:
- add WWAN subsystem to organize the WWAN interfaces better and
hopefully start driving towards more unified and vendor-
-independent APIs
- ethtool:
- add interface for reading IEEE MIB stats (incl. mlx5 and
bnxt support)
- allow network drivers to dump arbitrary SFP EEPROM data,
current offset+length API was a poor fit for modern SFP
which define EEPROM in terms of pages (incl. mlx5 support)
- act_police, flow_offload: add support for packet-per-second
policing (incl. offload for nfp)
- psample: add additional metadata attributes like transit delay
for packets sampled from switch HW (and corresponding egress
and policy-based sampling in the mlxsw driver)
- dsa: improve support for sandwiched LAGs with bridge and DSA
- netfilter:
- flowtable: use direct xmit in topologies with IP
forwarding, bridging, vlans etc.
- nftables: counter hardware offload support
- Bluetooth:
- improvements for firmware download w/ Intel devices
- add support for reading AOSP vendor capabilities
- add support for virtio transport driver

- allow concurrent monitor iface and ethernet rx decap
- set priority and queue mapping for injected frames
- phy: add support for Clause-45 PHY Loopback
- pci/iov: add sysfs MSI-X vector assignment interface
to distribute MSI-X resources to VFs (incl. mlx5 support)
New hardware/drivers:
- dsa: mv88e6xxx: add support for Marvell mv88e6393x -
11-port Ethernet switch with 8x 1-Gigabit Ethernet
and 3x 10-Gigabit interfaces.

Pure driver changes:
- add XDP support to: enetc, igc, stmmac
- add AF_XDP support to: stmmac
- virtio:
- page_to_skb() use build_skb when there's sufficient tailroom
(21% improvement for 1000B UDP frames)
- support XDP even without dedicated Tx queues - share the Tx
queues with the stack when necessary
- mlx5:
- flow rules: add support for mirroring with conntrack,
matching on ICMP, GTP, flex filters and more

net: mscc: ocelot: support PTP Sync one-step timestamping
Although HWTSTAMP_TX_ONESTEP_SYNC existed in ioctl for hardware timestamp configuration, the PTP Sync one-step timestamping had never been supported. This patch is to truely support it. - ocelot_port_txtstamp_request() This function handles tx timestamp request by storing ptp_cmd(tx timestamp type) in OCELOT_SKB_CB(skb)->ptp_cmd, and additionally for two-step timestamp storing ts_id in OCELOT_SKB_CB(clone)->ptp_cmd. - ocelot_ptp_rew_op() During xmit, this function is called to get rew_op (rewriter option) by checking skb->cb for tx timestamp request, and configure to transmitting. Non-onestep-Sync packet with one-step timestamp request falls back to use two-step timestamp.

net: dsa: free skb->cb usage in core driver
Free skb->cb usage in core driver and let device drivers decide to use or not. The reason having a DSA_SKB_CB(skb)->clone was because dsa_skb_tx_timestamp() which may set the clone pointer was called before p->xmit() which would use the clone if any, and the device driver has no way to initialize the clone pointer. This patch just put memset(skb->cb, 0, sizeof(skb->cb)) at beginning of dsa_slave_xmit(). Some new features in the future, like one-step timestamp may need more bytes of skb->cb to use in dsa_skb_tx_timestamp(), and p->xmit().

- Add ACPI support for RCPM driver
- Use generic io{read,write} for QE drivers after performance optimized
for PowerPC
- Fix QBMAN probe to cleanup HW states correctly for kexec
- Various cleanup and style fix for QBMAN/QE/GUTS drivers
OMAP:
- Preparation to use devicetree for genpd
- ti-sysc needs iorange check improved when the interconnect target module
has no control registers listed
- ti-sysc needs to probe l4_wkup and l4_cfg interconnects first to avoid
issues with missing resources and unnecessary deferred probe
- ti-sysc debug option can now detect more devices
- ti-sysc now warns if an old incomplete devicetree data is found as we
now rely on it being complete for am3 and 4
- soc init code needs to check for prcm and prm nodes for omap4/5 and dra7
- omap-prm driver needs to enable autoidle retention support for omap4
- omap5 clocks are missing gpmc and ocmc clock registers
- pci-dra7xx now needs to use builtin_platform_driver instead of using
builtin_platform_driver_probe for deferred probe to work
Raspberry Pi:
- Fix-up all RPi firmware drivers so as for unbind to happen in an
orderly fashion
- Support for RPi's PoE hat PWM bus
Qualcomm
- Improved detection for SCM calling conventions
- Support for OEM specific wifi firmware path

net: ocelot: replay switchdev events when joining bridge
The premise of this change is that the switchdev port attributes and objects offloaded by ocelot might have been missed when we are joining an already existing bridge port, such as a bonding interface. The patch pulls these switchdev attributes and objects from the bridge, on behalf of the 'bridge port' net device which might be either the ocelot switch interface, or the bonding upper interface. The ocelot_net.c belongs strictly to the switchdev ocelot driver, while ocelot.c is part of a library shared with the DSA felix driver. The ocelot_port_bridge_leave function (part of the common library) used to call ocelot_port_vlan_filtering(false), something which is not necessary for DSA, since the framework deals with that already there. So we move this function to ocelot_switchdev_unsync, which is specific to the switchdev driver. The code movement described above makes ocelot_port_bridge_leave no longer return an error code, so we change its type from int to void.

net: ocelot: support multiple bridges
The ocelot switches are a bit odd in that they do not have an STP state to put the ports into. Instead, the forwarding configuration is delayed from the typical port_bridge_join into stp_state_set, when the port enters the BR_STATE_FORWARDING state. I can only guess that the implementation of this quirk is the reason that led to the simplification of the driver such that only one bridge could be offloaded at a time. We can simplify the data structures somewhat, and introduce a per-port bridge device pointer and STP state, similar to how the LAG offload works now (there we have a per-port bonding device pointer and TX enabled state). This allows offloading multiple bridges with relative ease, while still keeping in place the quirk to delay the programming of the PGIDs. We actually need this change now because we need to remove the bogus restriction from ocelot_bridge_stp_state_set that ocelot->bridge_mask needs to contain BIT(port), otherwise that function is a no-op.

RISC-V Patches for the 5.12 Merge Window
I have a handful of new RISC-V related patches for this merge window:
* A check to ensure drivers are properly using uaccess. This isn't
manifesting with any of the drivers I'm currently using, but may catch
errors in new drivers.
* Some preliminary support for the FU740, along with the HiFive
Unleashed it will appear on.
* NUMA support for RISC-V, which involves making the arm64 code generic.
* Support for kasan on the vmalloc region.
* A handful of new drivers for the Kendryte K210, along with the DT
plumbing required to boot on a handful of K210-based boards.
* Support for allocating ASIDs.
* Preliminary support for kernels larger than 128MiB.
* Various other improvements to our KASAN support, including the
utilization of huge pages when allocating the KASAN regions.
We may have already found a bug with the KASAN_VMALLOC code, but it's
passing my tests. There's a fix in the works, but that will probably
miss the merge window.

clk: Add RISC-V Canaan Kendryte K210 clock driver
Add a clock provider driver for the Canaan Kendryte K210 RISC-V SoC. This new driver with the compatible string "canaan,k210-clk" implements support for the full clock structure of the K210 SoC. Since it is required for the correct operation of the SoC, this driver is selected by default for compilation when the SOC_CANAAN option is selected. With this change, the k210-sysctl driver is turned into a simple platform driver which enables its power bus clock and triggers populating its child nodes. The sysctl driver retains the SOC early initialization code, but the implementation now relies on the new function k210_clk_early_init() provided by the new clk-k210 driver. The clock structure implemented and many of the coding ideas for the driver come from the work by Sean Anderson on the K210 support for the U-Boot project.

net: mscc: ocelot: Add support for MRP
Add basic support for MRP. The HW will just trap all MRP frames on the ring ports to CPU and allow the SW to process them. In this way it is possible to for this node to behave both as MRM and MRC. Current limitations are: - it doesn't support Interconnect roles. - it supports only a single ring. - the HW should be able to do forwarding of MRP Test frames so the SW will not need to do this. So it would be able to have the role MRC without SW support. Signed-off-by: Horatiu Vultur <horatiu.vultur@microchip.com> Signed-off-by: David S. Miller <davem@davemloft.net> |

net: dsa: tag_ocelot_8021q: add support for PTP timestamping
For TX timestamping, we use the felix_txtstamp method which is common with the regular (non-8021q) ocelot tagger. This method says that skb deferral is needed, prepares a timestamp request ID, and puts a clone of the skb in a queue waiting for the timestamp IRQ. felix_txtstamp is called by dsa_skb_tx_timestamp() just before the tagger's xmit method. In the tagger xmit, we divert the packets classified by dsa_skb_tx_timestamp() as PTP towards the MMIO-based injection registers, and we declare them as dead towards dsa_slave_xmit. If not PTP, we proceed with normal tag_8021q stuff. Then the timestamp IRQ fires, the clone queued up from felix_txtstamp is matched to the TX timestamp retrieved from the switch's FIFO based on the timestamp request ID, and the clone is delivered to the stack. On RX, thanks to the VCAP IS2 rule that redirects the frames with an EtherType for 1588 towards two destinations: - the CPU port module (for MMIO based extraction) and - if the "no XTR IRQ" workaround is in place, the dsa_8021q CPU port the relevant data path processing starts in the ptp_classify_raw BPF classifier installed by DSA in the RX data path (post tagger, which is completely unaware that it saw a PTP packet). This time we can't reuse the same implementation of .port_rxtstamp that also works with the default ocelot tagger. That is because felix_rxtstamp is given an skb with a freshly stripped DSA header, and it says "I don't need deferral for its RX timestamp, it's right in it, let me show you"; and it just points to the header right behind skb->data, from where it unpacks the timestamp and annotates the skb with it. The same thing cannot happen with tag_ocelot_8021q, because for one thing, the skb did not have an extraction frame header in the first place, but a VLAN tag with no timestamp information. So the code paths in felix_rxtstamp for the regular and 8021q tagger are completely independent. With tag_8021q, the timestamp must come from the packet's duplicate delivered to the CPU port module, but there is potentially complex logic to be handled [ and prone to reordering ] if we were to just start reading packets from the CPU port module, and try to match them to the one we received over Ethernet and which needs an RX timestamp. So we do something simple: we tell DSA "give me some time to think" (we request skb deferral by returning false from .port_rxtstamp) and we just drop the frame we got over Ethernet with no attempt to match it to anything - we just treat it as a notification that there's data to be processed from the CPU port module's queues. Then we proceed to read the packets from those, one by one, which we deliver up the stack, timestamped, using netif_rx - the same function that any driver would use anyway if it needed RX timestamp deferral. So the assumption is that we'll come across the PTP packet that triggered the CPU extraction notification eventually, but we don't know when exactly. Thanks to the VCAP IS2 trap/redirect rule and the exclusion of the CPU port module from the flooding replicators, only PTP frames should be present in the CPU port module's RX queues anyway. There is just one conflict between the VCAP IS2 trapping rule and the semantics of the BPF classifier. Namely, ptp_classify_raw() deems general messages as non-timestampable, but still, those are trapped to the CPU port module since they have an EtherType of ETH_P_1588. So, if the "no XTR IRQ" workaround is in place, we need to run another BPF classifier on the frames extracted over MMIO, to avoid duplicates being sent to the stack (once over Ethernet, once over MMIO). It doesn't look like it's possible to install VCAP IS2 rules based on keys extracted from the 1588 frame headers.

net: mscc: ocelot: refactor ocelot_xtr_irq_handler into ocelot_xtr_poll
Since the felix DSA driver will need to poll the CPU port module for extracted frames as well, let's create some common functions that read an Extraction Frame Header, and then an skb, from a CPU extraction group. We abuse the struct ocelot_ops :: port_to_netdev function a little bit, in order to retrieve the DSA port net_device or the ocelot switchdev net_device based on the source port information from the Extraction Frame Header, but it's all in the benefit of code simplification - netdev_alloc_skb needs it. Originally, the port_to_netdev method was intended for parsing act->dev from tc flower offload code.

net: mscc: ocelot: use common tag parsing code with DSA
The Injection Frame Header and Extraction Frame Header that the switch prepends to frames over the NPI port is also prepended to frames delivered over the CPU port module's queues. Let's unify the handling of the frame headers by making the ocelot driver call some helpers exported by the DSA tagger. Among other things, this allows us to get rid of the strange cpu_to_be32 when transmitting the Injection Frame Header on ocelot, since the packing API uses network byte order natively (when "quirks" is 0). The comments above ocelot_gen_ifh talk about setting pop_cnt to 3, and the cpu extraction queue mask to something, but the code doesn't do it, so we don't do it either.

net: mscc: ocelot: offload bridge port flags to device
We should not be unconditionally enabling address learning, since doing that is actively detrimential when a port is standalone and not offloading a bridge. Namely, if a port in the switch is standalone and others are offloading the bridge, then we could enter a situation where we learn an address towards the standalone port, but the bridged ports could not forward the packet there, because the CPU is the only path between the standalone and the bridged ports. The solution of course is to not enable address learning unless the bridge asks for it. We need to set up the initial port flags for no learning and flooding everything, and also when the port joins and leaves the bridge. The flood configuration was already configured ok for standalone mode in ocelot_init, we just need to disable learning in ocelot_init_port.

net: dsa: felix: implement port flushing on .phylink_mac_link_down
There are several issues which may be seen when the link goes down while
forwarding traffic, all of which can be attributed to the fact that the
port flushing procedure from the reference manual was not closely
followed.
With flow control enabled on both the ingress port and the egress port,
it may happen when a link goes down that Ethernet packets are in flight.
In flow control mode, frames are held back and not dropped. When there
is enough traffic in flight (example: iperf3 TCP), then the ingress port
might enter congestion and never exit that state. This is a problem,
because it is the egress port's link that went down, and that has caused
the inability of the ingress port to send packets to any other port.
This is solved by flushing the egress port's queues when it goes down.
There is also a problem when performing stream splitting for
IEEE 802.1CB traffic (not yet upstream, but a sort of multicast,
basically). There, if one port from the destination ports mask goes
down, splitting the stream towards the other destinations will no longer
be performed. This can be traced down to this line:
ocelot_port_writel(ocelot_port, 0, DEV_MAC_ENA_CFG);
which should have been instead, as per the reference manual:
ocelot_port_rmwl(ocelot_port, 0, DEV_MAC_ENA_CFG_RX_ENA,
DEV_MAC_ENA_CFG);
Basically only DEV_MAC_ENA_CFG_RX_ENA should be disabled, but not
DEV_MAC_ENA_CFG_TX_ENA - I don't have further insight into why that is
the case, but apparently multicasting to several ports will cause issues
if at least one of them doesn't have DEV_MAC_ENA_CFG_TX_ENA set.
I am not sure what the state of the Ocelot VSC7514 driver is, but
probably not as bad as Felix/Seville, since VSC7514 uses phylib and has
the following in ocelot_adjust_link:
if (!phydev->link)
return;
therefore the port is not really put down when the link is lost, unlike
the DSA drivers which use .phylink_mac_link_down for that.
Nonetheless, I put ocelot_port_flush() in the common ocelot.c because it
needs to access some registers from drivers/net/ethernet/mscc/ocelot_rew.h
which are not exported in include/soc/mscc/ and a bugfix patch should
probably not move headers around.
Fixes:

net: mscc: ocelot: rebalance LAGs on link up/down events
At present there is an issue when ocelot is offloading a bonding interface, but one of the links of the physical ports goes down. Traffic keeps being hashed towards that destination, and of course gets dropped on egress. Monitor the netdev notifier events emitted by the bonding driver for changes in the physical state of lower interfaces, to determine which ports are active and which ones are no longer. Then extend ocelot_get_bond_mask to return either the configured bonding interfaces, or the active ones, depending on a boolean argument. The code that does rebalancing only needs to do so among the active ports, whereas the bridge forwarding mask and the logical port IDs still need to look at the permanently bonded ports.

net: mscc: ocelot: drop the use of the "lags" array
We can now simplify the implementation by always using ocelot_get_bond_mask to look up the other ports that are offloading the same bonding interface as us. In ocelot_set_aggr_pgids, the code had a way to uniquely iterate through LAGs. We need to achieve the same behavior by marking each LAG as visited, which we do now by using a temporary 32-bit "visited" bitmask. This is ok and we do not need dynamic memory allocation, because we know that this switch architecture will not have more than 32 ports (the PGID port masks are 32-bit anyway).

net: mscc: ocelot: set up the bonding mask in a way that avoids a net_device
Since this code should be called from pure switchdev as well as from DSA, we must find a way to determine the bonding mask not by looking directly at the net_device lowers of the bonding interface, since those could have different private structures. We keep a pointer to the bonding upper interface, if present, in struct ocelot_port. Then the bonding mask becomes the bitwise OR of all ports that have the same bonding upper interface. This adds a duplication of functionality with the current "lags" array, but the duplication will be short-lived, since further patches will remove the latter completely.

iommu/mediatek: Support master use iova over 32bit
After extending v7s, our pagetable already support iova reach 16GB(34bit). the master got the iova via dma_alloc_attrs may reach 34bits, but its HW register still is 32bit. then how to set the bit32/bit33 iova? this depend on a SMI larb setting(bank_sel). we separate whole 16GB iova to four banks: bank: 0: 0~4G; 1: 4~8G; 2: 8-12G; 3: 12-16G; The bank number is (iova >> 32). We will preassign which bank the larbs belong to. currently we don't have a interface for master to adjust its bank number. Each a bank is a iova_region which is a independent iommu-domain. the iova range for each iommu-domain can't cross 4G.

net: dsa: felix: perform switch setup for tag_8021q
Unlike sja1105, the only other user of the software-defined tag_8021q.c
tagger format, the implementation we choose for the Felix DSA switch
driver preserves full functionality under a vlan_filtering bridge
(i.e. IP termination works through the DSA user ports under all
circumstances).
The tag_8021q protocol just wants:
- Identifying the ingress switch port based on the RX VLAN ID, as seen
by the CPU. We achieve this by using the TCAM engines (which are also
used for tc-flower offload) to push the RX VLAN as a second, outer
tag, on egress towards the CPU port.
- Steering traffic injected into the switch from the network stack
towards the correct front port based on the TX VLAN, and consuming
(popping) that header on the switch's egress.
A tc-flower pseudocode of the static configuration done by the driver
would look like this:
$ tc qdisc add dev <cpu-port> clsact
$ for eth in swp0 swp1 swp2 swp3; do \
tc filter add dev <cpu-port> egress flower indev ${eth} \
action vlan push id <rxvlan> protocol 802.1ad; \
tc filter add dev <cpu-port> ingress protocol 802.1Q flower
vlan_id <txvlan> action vlan pop \
action mirred egress redirect dev ${eth}; \
done
but of course since DSA does not register network interfaces for the CPU
port, this configuration would be impossible for the user to do. Also,
due to the same reason, it is impossible for the user to inadvertently
delete these rules using tc. These rules do not collide in any way with
tc-flower, they just consume some TCAM space, which is something we can
live with.

net: mscc: ocelot: don't use NPI tag prefix for the CPU port module
Context: Ocelot switches put the injection/extraction frame header in
front of the Ethernet header. When used in NPI mode, a DSA master would
see junk instead of the destination MAC address, and it would most
likely drop the packets. So the Ocelot frame header can have an optional
prefix, which is just "ff:ff:ff:ff:ff:fe > ff:ff:ff:ff:ff:ff" padding
put before the actual tag (still before the real Ethernet header) such
that the DSA master thinks it's looking at a broadcast frame with a
strange EtherType.
Unfortunately, a lesson learned in commit

net: mscc: ocelot: store a namespaced VCAP filter ID
We will be adding some private VCAP filters that should not interfere in any way with the filters added using tc-flower. So we need to allocate some IDs which will not be used by tc. Currently ocelot uses an u32 id derived from the flow cookie, which in itself is an unsigned long. This is a problem in itself, since on 64 bit systems, sizeof(unsigned long)=8, so the driver is already truncating these. Create a struct ocelot_vcap_id which contains the full unsigned long cookie from tc, as well as a boolean that is supposed to namespace the filters added by tc with the ones that aren't.
