af42088bda octeontx2-af: Promisc enable/disable through mbox
In legacy silicon, promiscuous mode is only modified
through CGX mbox messages. In CN10KB silicon, it is modified
from CGX mbox and NIX. This breaks legacy application
behaviour. Fix this by removing call from NIX.

14bb236b29 octeontx-af: fix hardware timestamp configuration
MAC block on CN10K (RPM) supports hardware timestamp configuration. The
previous patch which added timestamp configuration support has a bug.
Though the netdev driver requests to disable timestamp configuration,
the driver is always enabling it.

This patch fixes the same.

79ebb53772 octeontx2-af: Add validation before accessing cgx and lmac
with the addition of new MAC blocks like CN10K RPM and CN10KB
RPM_USX, LMACs are noncontiguous and CGX blocks are also
noncontiguous. But during RVU driver initialization, the driver
is assuming they are contiguous and trying to access
cgx or lmac with their id which is resulting in kernel panic.

This patch fixes the issue by adding proper checks.

2e7bc57b97 octeontx2-af: Fix mapping for NIX block from CGX connection
Firmware configures NIX block mapping for all MAC blocks.
The current implementation reads the configuration and
creates the mapping between RVU PF  and NIX blocks. But
this configuration is only valid for silicons that support
multiple blocks. For all other silicons, all MAC blocks
map to NIX0.

This patch corrects the mapping by adding a check for the same.

4c5a331cac octeontx2-af: cn10kb: fix interrupt csr addresses
The current design is that, for asynchronous events like link_up and
link_down firmware raises the interrupt to kernel. The previous patch
which added RPM_USX driver has a bug where it uses old csr addresses
for configuring interrupts. Which is resulting in losing interrupts
from source firmware.

This patch fixes the issue by correcting csr addresses.

Linus Torvalds
3a8a670eee Networking changes for 6.5.
Core
 ----
 
  - Rework the sendpage & splice implementations. Instead of feeding
    data into sockets page by page extend sendmsg handlers to support
    taking a reference on the data, controlled by a new flag called
    MSG_SPLICE_PAGES. Rework the handling of unexpected-end-of-file
    to invoke an additional callback instead of trying to predict what
    the right combination of MORE/NOTLAST flags is.
    Remove the MSG_SENDPAGE_NOTLAST flag completely.
 
  - Implement SCM_PIDFD, a new type of CMSG type analogous to
    SCM_CREDENTIALS, but it contains pidfd instead of plain pid.
 
  - Enable socket busy polling with CONFIG_RT.
 
  - Improve reliability and efficiency of reporting for ref_tracker.
 
  - Auto-generate a user space C library for various Netlink families.
 
 Protocols
 ---------
 
  - Allow TCP to shrink the advertised window when necessary, prevent
    sk_rcvbuf auto-tuning from growing the window all the way up to
    tcp_rmem[2].
 
  - Use per-VMA locking for "page-flipping" TCP receive zerocopy.
 
  - Prepare TCP for device-to-device data transfers, by making sure
    that payloads are always attached to skbs as page frags.
 
  - Make the backoff time for the first N TCP SYN retransmissions
    linear. Exponential backoff is unnecessarily conservative.
 
  - Create a new MPTCP getsockopt to retrieve all info (MPTCP_FULL_INFO).
 
  - Avoid waking up applications using TLS sockets until we have
    a full record.
 
  - Allow using kernel memory for protocol ioctl callbacks, paving
    the way to issuing ioctls over io_uring.
 
  - Add nolocalbypass option to VxLAN, forcing packets to be fully
    encapsulated even if they are destined for a local IP address.
 
  - Make TCPv4 use consistent hash in TIME_WAIT and SYN_RECV. Ensure
    in-kernel ECMP implementation (e.g. Open vSwitch) select the same
    link for all packets. Support L4 symmetric hashing in Open vSwitch.
 
  - PPPoE: make number of hash bits configurable.
 
  - Allow DNS to be overwritten by DHCPACK in the in-kernel DHCP client
    (ipconfig).
 
  - Add layer 2 miss indication and filtering, allowing higher layers
    (e.g. ACL filters) to make forwarding decisions based on whether
    packet matched forwarding state in lower devices (bridge).
 
  - Support matching on Connectivity Fault Management (CFM) packets.
 
  - Hide the "link becomes ready" IPv6 messages by demoting their
    printk level to debug.
 
  - HSR: don't enable promiscuous mode if device offloads the proto.
 
  - Support active scanning in IEEE 802.15.4.
 
  - Continue work on Multi-Link Operation for WiFi 7.
 
 BPF
 ---
 
  - Add precision propagation for subprogs and callbacks. This allows
    maintaining verification efficiency when subprograms are used,
    or in fact passing the verifier at all for complex programs,
    especially those using open-coded iterators.
 
  - Improve BPF's {g,s}setsockopt() length handling. Previously BPF
    assumed the length is always equal to the amount of written data.
    But some protos allow passing a NULL buffer to discover what
    the output buffer *should* be, without writing anything.
 
  - Accept dynptr memory as memory arguments passed to helpers.
 
  - Add routing table ID to bpf_fib_lookup BPF helper.
 
  - Support O_PATH FDs in BPF_OBJ_PIN and BPF_OBJ_GET commands.
 
  - Drop bpf_capable() check in BPF_MAP_FREEZE command (used to mark
    maps as read-only).
 
  - Show target_{obj,btf}_id in tracing link fdinfo.
 
  - Addition of several new kfuncs (most of the names are self-explanatory):
    - Add a set of new dynptr kfuncs: bpf_dynptr_adjust(),
      bpf_dynptr_is_null(), bpf_dynptr_is_rdonly(), bpf_dynptr_size()
      and bpf_dynptr_clone().
    - bpf_task_under_cgroup()
    - bpf_sock_destroy() - force closing sockets
    - bpf_cpumask_first_and(), rework bpf_cpumask_any*() kfuncs
 
 Netfilter
 ---------
 
  - Relax set/map validation checks in nf_tables. Allow checking
    presence of an entry in a map without using the value.
 
  - Increase ip_vs_conn_tab_bits range for 64BIT builds.
 
  - Allow updating size of a set.
 
  - Improve NAT tuple selection when connection is closing.
 
 Driver API
 ----------
 
  - Integrate netdev with LED subsystem, to allow configuring HW
    "offloaded" blinking of LEDs based on link state and activity
    (i.e. packets coming in and out).
 
  - Support configuring rate selection pins of SFP modules.
 
  - Factor Clause 73 auto-negotiation code out of the drivers, provide
    common helper routines.
 
  - Add more fool-proof helpers for managing lifetime of MDIO devices
    associated with the PCS layer.
 
  - Allow drivers to report advanced statistics related to Time Aware
    scheduler offload (taprio).
 
  - Allow opting out of VF statistics in link dump, to allow more VFs
    to fit into the message.
 
  - Split devlink instance and devlink port operations.

72dc6db7e3 workqueue: Ordered workqueue creation cleanups
For historical reasons, unbound workqueues with max concurrency limit of 1
 are considered ordered, even though the concurrency limit hasn't been
 system-wide for a long time. This creates ambiguity around whether ordered
 execution is actually required for correctness, which was actually confusing
 for e.g. btrfs (btrfs updates are being routed through the btrfs tree).
 
 There aren't that many users in the tree which use the combination and there
 are pending improvements to unbound workqueue affinity handling which will
 make inadvertent use of ordered workqueue a bigger loss. This pull request
 clarifies the situation for most of them by updating the ones which require
 ordered execution to use alloc_ordered_workqueue().
 
 There are some conversions being routed through subsystem-specific trees and
 likely a few stragglers. Once they're all converted, workqueue can trigger a
 warning on unbound + @max_active==1 usages and eventually drop the implicit
 ordered behavior.

e18aab0470 octeontx2-af: Set XOFF on other child transmit schedulers during SMQ flush
When multiple transmit scheduler queues feed a TL1 transmit link, the
SMQ flush initiated on a low priority queue might get stuck when a high
priority queue fully subscribes the transmit link. This inturn effects
interface teardown. To avoid this, temporarily XOFF all TL1's other
immediate child transmit scheduler queues and also clear any rate limit
configuration on all the scheduler queues in SMQ(flush) hierarchy.

The DWRR MTU config added for SDP and RPM/LBK links on CN10K
silicon is further extended on CK10KB silicon variant and made
it configurable. Now there are 4 DWRR MTU config to choose while
setting transmit scheduler's RR_WEIGHT.

Here we are reserving one config for each of RPM, SDP and LBK.
NIXX_AF_DWRR_MTUX(0) ---> RPM
NIXX_AF_DWRR_MTUX(1) ---> SDP
NIXX_AF_DWRR_MTUX(2) ---> LBK

PF/VF drivers can choose the DWRR_MTU to be used by setting
SMQX_CFG[pkt_link_type] to one of above. TLx_SCHEDULE[RR_WEIGHT]
is to be as configured 'quantum / 2^DWRR_MTUX[MTU]'. DWRR_MTU
of each link is exposed to PF/VF drivers via mailbox for
RR_WEIGHT calculation.

79bc788c03 octeontx2-af: extend RSS supported offload types
Add support to select L3 SRC or DST only, L4 SRC or DST only for RSS
calculation.

AF consumer may have requirement as we can select only SRC or DST data for
RSS calculation in L3, L4 layers. With this requirement there will be
following combinations, IPV[4,6]_SRC_ONLY, IPV[4,6]_DST_ONLY,
[TCP,UDP,SCTP]_SRC_ONLY, [TCP,UDP,SCTP]_DST_ONLY. So, instead of creating
a bit for each combination, we are using upper 4 bits (31:28) in the
flow_key_cfg to represent the SRC, DST selection. 31 => L3_SRC,
30 => L3_DST, 29 => L4_SRC, 28 => L4_DST. These won't be part of flow_cfg,
so that we don't need to change the existing ABI.

09de114c77 octeontx2-af: Add devlink option to adjust mcam high prio zone entries
The NPC MCAM entries are currently divided into three priority zones
in AF driver: high, mid, and low. The high priority zone and low priority
zone take up 1/8th (each) of the available MCAM entries, and remaining
going to the mid priority zone.

The current allocation scheme may not meet certain requirements, such
as when a requester needs more high priority zone entries than are
reserved. This patch adds a devlink configurable option to increase the
number of high priority zone entries that can be allocated by requester.
The max number of entries that can be reserved for high priority usage
is 100% of available MCAM entries.

Usage:
1) Change high priority zone percentage to 75%:
devlink -p dev param set pci/0002:01:00.0 name npc_mcam_high_zone_percent \
value 75 cmode runtime

2) Read high priority zone percentage:
devlink -p dev param show pci/0002:01:00.0 name npc_mcam_high_zone_percent

The devlink set configuration is only permitted when no MCAM entries
are assigned, i.e., all MCAM entries are free, indicating that no PF/VF
driver is loaded. So user must unload/unbind PF/VF driver/devices before
modifying the high priority zone percentage.

2. mlx5_tc_ct_set_tuple_match(): Used as part of netfilter offload,

6b4b2ded9c octeontx2-pf: Refactor schedular queue alloc/free calls
1. Upon txschq free request, the transmit schedular config in hardware
is not getting reset. This patch adds necessary changes to do the same.

2. Current implementation calls txschq alloc during interface
initialization and in response handler updates the default txschq array.
This creates a problem for htb offload where txsch alloc will be called
for every tc class. This patch addresses the issue by reading txschq
response in mbox caller function instead in the response handler.

3. Current otx2_txschq_stop routine tries to free all txschq nodes
allocated to the interface. This creates a problem for htb offload.
This patch introduces the otx2_txschq_free_one to free txschq in a
given level.

Now that we no longer need to check whether the DMA address is within

Instead, use order-1 (8k) allocations, which will result in 32 order-1
pages containing 32 TSO headers.

f00ba4f41a net: mvneta: use buf->type to determine whether to dma-unmap
Now that we use a different buffer type for TSO headers, we can use
buf->type to determine whether the original buffer was DMA-mapped or
not. The rules are:

	MVNETA_TYPE_XDP_TX - from a DMA pool, no unmap is required
	MVNETA_TYPE_XDP_NDO - dma_map_single()'d
	MVNETA_TYPE_SKB - normal skbuff, dma_map_single()'d
	MVNETA_TYPE_TSO - from the TSO buffer area

This means we only need to call dma_unmap_single() on the XDP_NDO and
SKB types of buffer, and we no longer need the private IS_TSO_HEADER()
which relies on the TSO region being contiguously allocated.

bd9424efc4 macsec: Use helper macsec_netdev_priv for offload drivers
Now macsec on top of vlan can be offloaded to macsec offloading
devices so that VLAN tag is sent in clear text on wire i.e,
packet structure is DMAC|SMAC|VLAN|SECTAG. Offloading devices can
simply enable NETIF_F_HW_MACSEC feature in netdev->vlan_features for
this to work. But the logic in offloading drivers to retrieve the
private structure from netdev needs to be changed to check whether
the netdev received is real device or a vlan device and get private
structure accordingly. This patch changes the offloading drivers to
use helper macsec_netdev_priv instead of netdev_priv.

289f974674 net: octeontx2: Use alloc_ordered_workqueue() to create ordered workqueues
BACKGROUND
==========

When multiple work items are queued to a workqueue, their execution order
doesn't match the queueing order. They may get executed in any order and
simultaneously. When fully serialized execution - one by one in the queueing
order - is needed, an ordered workqueue should be used which can be created
with alloc_ordered_workqueue().

However, alloc_ordered_workqueue() was a later addition. Before it, an
ordered workqueue could be obtained by creating an UNBOUND workqueue with
@max_active==1. This originally was an implementation side-effect which was
broken by 4c16bd327c ("workqueue: restore WQ_UNBOUND/max_active==1 to be
ordered"). Because there were users that depended on the ordered execution,
5c0338c687 ("workqueue: restore WQ_UNBOUND/max_active==1 to be ordered")
made workqueue allocation path to implicitly promote UNBOUND workqueues w/
@max_active==1 to ordered workqueues.

While this has worked okay, overloading the UNBOUND allocation interface
this way creates other issues. It's difficult to tell whether a given
workqueue actually needs to be ordered and users that legitimately want a
min concurrency level wq unexpectedly gets an ordered one instead. With
planned UNBOUND workqueue updates to improve execution locality and more
prevalence of chiplet designs which can benefit from such improvements, this
isn't a state we wanna be in forever.

This patch series audits all callsites that create an UNBOUND workqueue w/
@max_active==1 and converts them to alloc_ordered_workqueue() as necessary.

WHAT TO LOOK FOR
================

The conversions are from

  alloc_workqueue(WQ_UNBOUND | flags, 1, args..)

to 

  alloc_ordered_workqueue(flags, args...)

which don't cause any functional changes. If you know that fully ordered
execution is not ncessary, please let me know. I'll drop the conversion and
instead add a comment noting the fact to reduce confusion while conversion
is in progress.

If you aren't fully sure, it's completely fine to let the conversion
through. The behavior will stay exactly the same and we can always
reconsider later.

As there are follow-up workqueue core changes, I'd really appreciate if the
patch can be routed through the workqueue tree w/ your acks. Thanks.

same counter in hardware. If SecY replay_protect is true
then counter represents InPktsLate otherwise InPktsDelayed.
This mode change was tracked based on protect_frames
instead of replay_protect mistakenly. Similarly InPktsUnchecked
and InPktsOk share same counter and mode change was tracked
based on validate_check instead of validate_disabled.
This patch fixes those problems.

57d00d4364 octeontx2-pf: mcs: Match macsec ethertype along with DMAC
On CN10KB silicon a single hardware macsec block is
present and offloads macsec operations for all the
ethernet LMACs. TCAM match with macsec ethertype 0x88e5
alone at RX side is not sufficient to distinguish all the
macsec interfaces created on top of netdevs. Hence append
the DMAC of the macsec interface too. Otherwise the first
created macsec interface only receives all the macsec traffic.

709d0b880c octeontx2-af: update type of prof fields in nix_aw_enq_req
Update type of prof and prof_mask fields in nix_as_enq_req
from u64 to struct nix_bandprof_s, which is 128 bits wide.

This is to address warnings with compiling with gcc-12 W=1
regarding string fortification.

Although the union of which these fields are a member is 128bits
wide, and thus writing a 128bit entity is safe, the compiler flags
a problem as the field being written is only 64 bits wide.

2960a2d33b net: mvneta: fix potential double-frees in mvneta_txq_sw_deinit()
Reported on the Turris forum, mvneta provokes kernel warnings in the
architecture DMA mapping code when mvneta_setup_txqs() fails to
allocate memory. This happens because when mvneta_cleanup_txqs() is
called in the mvneta_stop() path, we leave pointers in the structure
that have been freed.

Then on mvneta_open(), we call mvneta_setup_txqs(), which starts
allocating memory. On memory allocation failure, mvneta_cleanup_txqs()
will walk all the queues freeing any non-NULL pointers - which includes
pointers that were previously freed in mvneta_stop().

Fix this by setting these pointers to NULL to prevent double-freeing
of the same memory.

fe3f4c292d octeon_ep: Drop redundant pci_enable_pcie_error_reporting()
pci_enable_pcie_error_reporting() enables the device to send ERR_*
Messages.  Since f26e58bf6f ("PCI/AER: Enable error reporting when AER is
native"), the PCI core does this for all devices during enumeration, so the
driver doesn't need to do it itself.

Remove the redundant pci_enable_pcie_error_reporting() call from the
driver.  Also remove the corresponding pci_disable_pcie_error_reporting()
from the driver .remove() path.

Note that this only controls ERR_* Messages from the device.  An ERR_*
Message may cause the Root Port to generate an interrupt, depending on the
AER Root Error Command register managed by the AER service driver.

When checksum offload is disabled in the driver via ethtool,
the PTP 1-step sync packets contain incorrect checksum, since
the stack calculates the checksum before driver updates
PTP timestamp field in the packet. This results in PTP packets
getting dropped at the other end. This patch fixes the issue by
re-calculating the UDP checksum after updating PTP
timestamp field in the driver.

66c0e13ad2 drivers: net: turn on XDP features
A summary of the flags being set for various drivers is given below.
Note that XDP_F_REDIRECT_TARGET and XDP_F_FRAG_TARGET are features
that can be turned off and on at runtime. This means that these flags
may be set and unset under RTNL lock protection by the driver. Hence,
READ_ONCE must be used by code loading the flag value.

Also, these flags are not used for synchronization against the availability
of XDP resources on a device. It is merely a hint, and hence the read
may race with the actual teardown of XDP resources on the device. This
may change in the future, e.g. operations taking a reference on the XDP
resources of the driver, and in turn inhibiting turning off this flag.
However, for now, it can only be used as a hint to check whether device
supports becoming a redirection target.

Turn 'hw-offload' feature flag on for:
 - netronome (nfp)
 - netdevsim.

Turn 'native' and 'zerocopy' features flags on for:
 - intel (i40e, ice, ixgbe, igc)
 - mellanox (mlx5).
 - stmmac
 - netronome (nfp)

Turn 'native' features flags on for:
 - amazon (ena)
 - broadcom (bnxt)
 - freescale (dpaa, dpaa2, enetc)

 - qlogic (qede)
 - sfc
 - socionext (netsec)

Turn 'basic' (tx, pass, aborted and drop) features flags on for:

 - cavium (thunder)
 - hyperv.

Turn 'redirect_target' feature flag on for:
 - amanzon (ena)

d5b2e0a299 octeontx2-af: restore rxc conf after teardown sequence
CN10K CPT coprocessor includes a component named RXC which
is responsible for reassembly of inner IP packets. RXC has
the feature to evict oldest entries based on age/threshold.
The age/threshold is being set to minimum values to evict
all entries at the time of teardown.
This patch adds code to restore timeout and threshold config
after teardown sequence is complete as it is global config.

d41e127757 net: mdio: Rework scanning of bus ready for quirks
Some C22 PHYs do bad things when there are C45 transactions on the
bus. In order to handle this, the bus needs to be scanned first for
C22 at all addresses, and then C45 scanned for all addresses.

The Marvell pxa168 driver scans a specific address on the bus to find
its PHY. This is a C22 only device, so update it to use the c22
helper.

55ba18dc62 octeontx2-pf: Fix the use of GFP_KERNEL in atomic context on rt
The commit 4af1b64f80 ("octeontx2-pf: Fix lmtst ID used in aura
free") uses the get/put_cpu() to protect the usage of percpu pointer
in ->aura_freeptr() callback, but it also unnecessarily disable the
preemption for the blockable memory allocation. The commit 87b93b678e
("octeontx2-pf: Avoid use of GFP_KERNEL in atomic context") tried to
fix these sleep inside atomic warnings. But it only fix the one for
the non-rt kernel. For the rt kernel, we still get the similar warnings
like below.

Of course, we can shuffle the get/put_cpu() to only wrap the invocation
of ->aura_freeptr() as what commit 87b93b678e does. But there are only
two ->aura_freeptr() callbacks, otx2_aura_freeptr() and
cn10k_aura_freeptr(). There is no usage of perpcu variable in the
otx2_aura_freeptr() at all, so the get/put_cpu() seems redundant to it.
We can move the get/put_cpu() into the corresponding callback which
really has the percpu variable usage and avoid the sprinkling of
get/put_cpu() in several places.

4af1b64f80 octeontx2-pf: Fix lmtst ID used in aura free
Current code uses per_cpu pointer to get the lmtst_id mapped to
the core on which aura_free() is executed. Using per_cpu pointer
without preemption disable causing mismatch between lmtst_id and
core on which pointer gets freed. This patch fixes the issue by
disabling preemption around aura_free.

292a089d78 treewide: Convert del_timer*() to timer_shutdown*()
Due to several bugs caused by timers being re-armed after they are
shutdown and just before they are freed, a new state of timers was added
called "shutdown".  After a timer is set to this state, then it can no
longer be re-armed.

The following script was run to find all the trivial locations where
del_timer() or del_timer_sync() is called in the same function that the
object holding the timer is freed.  It also ignores any locations where
the timer->function is modified between the del_timer*() and the free(),
as that is not considered a "trivial" case.

This was created by using a coccinelle script and the following
commands:

    $ cat timer.cocci
    @@
    expression ptr, slab;
    identifier timer, rfield;
    @@
    (
    -       del_timer(&ptr->timer);
    +       timer_shutdown(&ptr->timer);
    |
    -       del_timer_sync(&ptr->timer);
    +       timer_shutdown_sync(&ptr->timer);
    )
      ... when strict

cdd97383e1 net: mvneta: Fix an out of bounds check
In an earlier commit, I added a bounds check to prevent an out of bounds
read and a WARN().  On further discussion and consideration that check
was probably too aggressive.  Instead of returning -EINVAL, a better fix
would be to just prevent the out of bounds read but continue the process.

Background: The value of "pp->rxq_def" is a number between 0-7 by default,
or even higher depending on the value of "rxq_number", which is a module
parameter. If the value is more than the number of available CPUs then
it will trigger the WARN() in cpu_max_bits_warn().

b9d0fedc62 octeontx2-af: cn10kb: Add RPM_USX MAC support
OcteonTx2's next gen platform the CN10KB has RPM_USX MAC which has a
different serdes when compared to RPM MAC. Though the underlying
HW is different, the CSR interface has been designed largely inline
with RPM MAC, with few exceptions though. So we are using the same
CGX driver for RPM_USX MAC as well and will have a different set of APIs
for RPM_USX where ever necessary.

The RPM and RPM_USX blocks support a different number of LMACS.
RPM_USX support 8 LMACS per MAC block whereas legacy RPM supports only 4
LMACS per MAC. with this RPM_USX support double the number of DMAC filters
and fifo size.

This patch adds initial support for CN10KB's RPM_USX  MAC i.e registering
the driver and defining MAC operations (mac_ops). Adds the logic to
configure internal loopback and pause frames and assign FIFO length to
LMACS.

Kernel reads lmac features like lmac type, autoneg, etc from shared
firmware data this structure only supports 4 lmacs per MAC, this patch
extends this structure to accommodate 8 lmacs.

f2e664ad50 octeontx2-af: Support variable number of lmacs
Most of the code in CGX/RPM driver assumes that max lmacs per
given MAC as always, 4 and the number of MAC blocks also as 4.
With this assumption, the max number of interfaces supported is
hardcoded to 16. This creates a problem as next gen CN10KB silicon
MAC supports 8 lmacs per MAC block.

This patch solves the problem by using "max lmac per MAC block"
value from constant csrs and uses cgx_cnt_max value which is
populated based number of MAC blocks supported by silicon.

6d135d9e2b octeontx2-af: Fix the size of memory allocated for the 'id_bmap' bitmap
This allocation is really spurious.
The size of the bitmap is 'tot_ids' and it is used as such in the driver.

So we could expect something like:
   table->id_bmap = devm_kcalloc(rvu->dev, BITS_TO_LONGS(table->tot_ids),
			         sizeof(long), GFP_KERNEL);

However, when the bitmap is allocated, we allocate:
   BITS_TO_LONGS(table->tot_ids) * table->tot_ids ~=
   table->tot_ids / 32 * table->tot_ids ~=
   table->tot_ids^2 / 32

It is proportional to the square of 'table->tot_ids' which seems to
potentially be big.

Allocate the expected amount of memory, and switch to the bitmap API to
have it more straightforward.

7a74c1265a net: mvpp2: Consider NVMEM cells as possible MAC address source
The ONIE standard describes the organization of tlv (type-length-value)
arrays commonly stored within NVMEM devices on common networking
hardware.

Several drivers already make use of NVMEM cells for purposes like
retrieving a default MAC address provided by the manufacturer.

What made ONIE tables unusable so far was the fact that the information
where "dynamically" located within the table depending on the
manufacturer wishes, while Linux NVMEM support only allowed statically
defined NVMEM cells. Fortunately, this limitation was eventually tackled
with the introduction of discoverable cells through the use of NVMEM
layouts, making it possible to extract and consistently use the content
of tables like ONIE's tlv arrays.

Parsing this table at runtime in order to get various information is now
possible. So, because many Marvell networking switches already follow
this standard, let's consider using NVMEM cells as a new valid source of
information when looking for a base MAC address, which is one of the
primary uses of these new fields. Indeed, manufacturers following the
ONIE standard are encouraged to provide a default MAC address there, so
let's eventually use it if no other MAC address has been found using the
existing methods.

supported by the profile then avoid installing broadcast and multicast
rules.
2. Allow MCAM entry insertion for promiscuous mode.
3. For the profiles where DMAC is not extracted in MKEX key default
unicast entry installed by AF is not valid. Hence do not use action
from the AF installed default unicast entry for such cases.
4. Adjacent packet header fields in a packet like IP header source
and destination addresses or UDP/TCP header source port and destination
can be extracted together in MKEX profile. Therefore MKEX profile can be
configured to in two ways:
	a. Total of 4 bytes from start of UDP header(src port
	   + destination port)
	or
	b. Two bytes from start and two bytes from offset 2

d66608803a octeontx2-af: debugsfs: fix pci device refcount leak
As comment of pci_get_domain_bus_and_slot() says, it returns
a pci device with refcount increment, when finish using it,
the caller must decrement the reference count by calling
pci_dev_put().

So before returning from rvu_dbg_rvu_pf_cgx_map_display() or
cgx_print_dmac_flt(), pci_dev_put() is called to avoid refcount
leak.

Add a new union, to access both fields in a single load/store

	union {
		u32	vlan_all;
		struct {
		__be16	vlan_proto;
		__u16	vlan_tci;

fb4a5dfca0 prestera: matchall: do not rollback if rule exists
If you try to create a 'mirror' ACL rule on a port that already has a
mirror rule, prestera_span_rule_add() will fail with EEXIST error.

This forces rollback procedure which destroys existing mirror rule on
hardware leaving it visible in linux.

Add an explicit check for EEXIST to prevent the deletion of the existing
rule but keep user seeing error message:

  $ tc filter add dev sw1p1 ... skip_sw action mirred egress mirror dev sw1p2
  $ tc filter add dev sw1p1 ... skip_sw action mirred egress mirror dev sw1p3
  RTNETLINK answers: File exists
  We have an error talking to the kernel

ae15ed6e40 net: marvell: prestera: Propagate nh state from hw to kernel
We poll nexthops in HW and call for each active nexthop appropriate
neighbour.

Also we provide implicity neighbour resolving.
For example, user have added nexthop route:
  # ip route add 5.5.5.5 via 1.1.1.2
But neighbour 1.1.1.2 doesn't exist. In this case we will try to call
neigh_event_send, even if there is no traffic.
This is useful, when you have add route, which will be used after some
time but with a lot of traffic (burst). So, we has prepared, offloaded
route in advance.

0152dfee23 net: mvpp2: fix mvpp2 debugfs leak
When mvpp2 is unloaded, the driver specific debugfs directory is not
removed, which technically leads to a memory leak. However, this
directory is only created when the first device is probed, so the
hardware is present. Removing the module is only something a developer
would to when e.g. testing out changes, so the module would be
reloaded. So this memory leak is minor.

The original attempt in commit fe2c9c61f6 ("net: mvpp2: debugfs: fix
memory leak when using debugfs_lookup()") that was labelled as a memory
leak fix was not, it fixed a refcount leak, but in doing so created a
problem when the module is reloaded - the directory already exists, but
mvpp2_root is NULL, so we lose all debugfs entries. This fix has been
reverted.

This is the alternative fix, where we remove the offending directory
whenever the driver is unloaded.

c54ffc7360 octeontx2-pf: mcs: Introduce MACSEC hardware offloading
This patch introduces the macsec offload feature to cn10k
PF netdev driver. The macsec offload ops like adding, deleting
and updating SecYs, SCs, SAs and stats are supported. XPN support
will be added in later patches. Some stats use same counter in hardware
which means based on the SecY mode the same counter represents different
stat. Hence when SecY mode/policy is changed then snapshot of current
stats are captured. Also there is no provision to specify the unique
flow-id/SCI per packet to hardware hence different mac address needs to
be set for macsec interfaces.

CN10K-B and CNF10K-B has macsec block(MCS) to encrypt and
decrypt packets at MAC level. This block is a global resource
with hardware resources like SecYs, SCs and SAs and is in
between NIX block and RPM LMAC. CN10K-B silicon has only one MCS
block which receives packets from all LMACS whereas CNF10K-B has
seven MCS blocks for seven LMACs. Both MCS blocks are
similar in operation except for few register offsets and some
configurations require writing to different registers. Those
differences between IPs are handled using separate ops.
This patch adds basic driver and does the initial hardware
calibration and parser configuration.

2ef4e45d99 octeontx2-af: Add PTP PPS Errata workaround on CN10K silicon
Errata:
The ptp_clock_hi rollsover to zero one clock cycle before it
reaches one second boundary. As a result, the pps threshold
comparison fails after one second and the pps output signal
won't toggle further.

This patch workarounds the issue by programming the pps_lo_incr
register to 500msec minus one clock cycle period, ensuring that
the pps threshold comparison succeeds at one second rollover
boundary and pps edge toggles. After that point, the driver will
have enough time (~500msec) to reset the pps threshold value.
After each one second boundary, hrtimer is invoked which resets
the pps threshold value.

Add support for ptp 1-step mode using timecounter. The seconds and
nanoseconds to be updated in PTP header are calculated by adding the
timecounter offset to the free running PTP clock counter time. The PF
driver periodically gets the PTP clock time using AF mbox. The 1-step
support uses HW feature to update correction field rather than
OriginTimestamp field in PTP header.

When calling debugfs_lookup() the result must have dput() called on it,
otherwise the memory will leak over time.  Fix this up to be much
simpler logic and only create the root debugfs directory once when the

99c969a83d octeontx2-pf: Add egress PFC support
As of now all transmit queues transmit packets out of same scheduler
queue hierarchy. Due to this PFC frames sent by peer are not handled
properly, either all transmit queues are backpressured or none.
To fix this when user enables PFC for a given priority map relavant
transmit queue to a different scheduler queue hierarcy, so that
backpressure is applied only to the traffic egressing out of that TXQ.

44af95718f net: prestera: manage matchall and flower priorities
matchall rules can be added only to chain 0 and their priorities have
limitations:
 - new matchall ingress rule's priority must be higher (lower value)
   than any existing flower rule;
 - new matchall egress rule's priority must be lower (higher value)
   than any existing flower rule.

The opposite works for flower rule adding:
 - new flower ingress rule's priority must be lower (higher value)
   than any existing matchall rule;
 - new flower egress rule's priority must be higher (lower value)
   than any existing matchall rule.

This is a hardware limitation and thus must be properly handled in
driver by reporting errors to the user when newly added rule has such a
priority that cannot be installed into the hardware.

To achieve this, the driver must maintain both min/max matchall
priorities for every flower block when user adds/deletes a matchall
rule, as well as both min/max flower priorities for chain 0 for every
adding/deletion of flower rules for chain 0.

13c9f4dc10 octeontx2-pf: Fix NIX_AF_TL3_TL2X_LINKX_CFG register configuration
For packets scheduled to RPM and LBK, NIX_AF_PSE_CHANNEL_LEVEL[BP_LEVEL]
selects the TL3 or TL2 scheduling level as the one used for link/channel
selection and backpressure. For each scheduling queue at the selected
level: Setting NIX_AF_TL3_TL2(0..255)_LINK(0..12)_CFG[ENA] = 1 allows
the TL3/TL2 queue to schedule packets to a specified RPM or LBK link
and channel.

There is an issue in the code where NIX_AF_PSE_CHANNEL_LEVEL[BP_LEVEL]
is set to TL3 where as the NIX_AF_TL3_TL2(0..255)_LINK(0..12)_CFG is
configured for TL2 queue in some cases. As a result packets will not
transmit on that link/channel. This patch fixes the issue by configuring
the NIX_AF_TL3_TL2(0..255)_LINK(0..12)_CFG register depending on the
NIX_AF_PSE_CHANNEL_LEVEL[BP_LEVEL] value.

deef0d6afe net: marvell: prestera: implement software MDB entries allocation
Define bridge MDB entry (software entry):
  - entry that get's created upon receiving MDB management events
    (create/delete), that inherently defines a software entry,
    which can be enabled (offloaded to the HW) or disabled (removed
    from HW).
    This separation is done to achieve a better highlevel
    management of HW resources - software MDB entry could exist,
    while it's not necessarily should be configured on the HW.
    For example: by default, the Linux behavior would not replicate
    multicast traffic to multicast group members if there's no
    active multicast router and thus - no actual multicast traffic
    can be received/sent. So, until multicast router appears on the
    system no HW configuration should be applied, although SW MDB entries
    should be tracked.
    Another example would be altering state of 'multicast enabled' on
    the bridge: MC_DISABLED should invoke disabling / clearing multicast
    groups of specified bridge on the HW, yet upon receiving 'multicast
    enabled' event, driver should reconfigure any existing software MDB
    groups on the HW.
    Keeping track of software MDB entries in such way makes it possible
    to properly react on such events.
Define bridge MDB port entry (software entry):
  - entry that helps keeping track (on software - driver - level) of which
    bridge mebemer interface joined any give MDB group;

504148fedb net: add skb_[inner_]tcp_all_headers helpers
Most drivers use "skb_transport_offset(skb) + tcp_hdrlen(skb)"
to compute headers length for a TCP packet, but others
use more convoluted (but equivalent) ways.

Add skb_tcp_all_headers() and skb_inner_tcp_all_headers()
helpers to harmonize this a bit.

In some places, octeontx2 code calls bitmap_weight() to check if any bit of

because bitmap_empty() stops traversing the bitmap as soon as it finds
first set bit, while bitmap_weight() counts all bits unconditionally.

As an outcome of that comment all the dance around setting such
driver version to FW should be removed too, because in upstream
kernel whole driver will have same version so read/write from/to
FW will give same result.

e8bd70250a prestera: acl: add action hw_stats support
Currently, when user adds a tc action and the action gets offloaded,
the user expects the HW stats to be counted also. This limits the
amount of supported offloaded filters, as HW counter resources may
be quite limited. Without counter assigned, the HW is capable to
carry much more filters.

To resolve the issue above, the following types of HW stats are
offloaded and supported by the driver:

any       - current default, user does not care about the type.
delayed   - polled from HW periodically.
disabled  - no HW stats needed.
immediate - not supported.

Example:
  tc filter add dev PORT ingress proto ip flower skip_sw ip_proto 0x11 \
    action drop
  tc filter add dev PORT ingress proto ip flower skip_sw ip_proto 0x12 \
    action drop hw_stats disabled
  tc filter add dev sw1p1 ingress proto ip flower skip_sw ip_proto 0x14 \
    action drop hw_stats delayed

11f8e7c122 net: ethernet: mv643xx: Fix over zealous checking of_get_mac_address()
There is often not a MAC address available in an EEPROM accessible by
Linux with Marvell devices. Instead the bootload has the MAC address
and directly programs it into the hardware. So don't consider an error
from of_get_mac_address() has fatal. However, the check was added for
the case where there is a MAC address in an the EEPROM, but the EEPROM
has not probed yet, and -EPROBE_DEFER is returned. In that case the
error should be returned. So make the check specific to this error
code.

33b5bc9e70 octeontx2-af: initialize action variable
Clang static analysis reports this representative issue
rvu_npc.c:898:15: warning: Assigned value is garbage
  or undefined
  req.match_id = action.match_id;
               ^ ~~~~~~~~~~~~~~~

The initial setting of action is conditional on
 if (is_mcam_entry_enabled(...))
The later check of action.op will sometimes be garbage.
So initialize action.

Reduce setting of
  *(u64 *)&action = 0x00;
to
  *(u64 *)&action = 0;

Linus Torvalds
169e77764a Networking changes for 5.18.
Core
 ----
 
  - Introduce XDP multi-buffer support, allowing the use of XDP with
    jumbo frame MTUs and combination with Rx coalescing offloads (LRO).
 
  - Speed up netns dismantling (5x) and lower the memory cost a little.
    Remove unnecessary per-netns sockets. Scope some lists to a netns.
    Cut down RCU syncing. Use batch methods. Allow netdev registration
    to complete out of order.
 
  - Support distinguishing timestamp types (ingress vs egress) and
    maintaining them across packet scrubbing points (e.g. redirect).
 
  - Continue the work of annotating packet drop reasons throughout
    the stack.
 
  - Switch netdev error counters from an atomic to dynamically
    allocated per-CPU counters.
 
  - Rework a few preempt_disable(), local_irq_save() and busy waiting
    sections problematic on PREEMPT_RT.
 
  - Extend the ref_tracker to allow catching use-after-free bugs.
 
 BPF
 ---
 
  - Introduce "packing allocator" for BPF JIT images. JITed code is
    marked read only, and used to be allocated at page granularity.
    Custom allocator allows for more efficient memory use, lower
    iTLB pressure and prevents identity mapping huge pages from
    getting split.
 
  - Make use of BTF type annotations (e.g. __user, __percpu) to enforce
    the correct probe read access method, add appropriate helpers.
 
  - Convert the BPF preload to use light skeleton and drop
    the user-mode-driver dependency.
 
  - Allow XDP BPF_PROG_RUN test infra to send real packets, enabling
    its use as a packet generator.
 
  - Allow local storage memory to be allocated with GFP_KERNEL if called
    from a hook allowed to sleep.
 
  - Introduce fprobe (multi kprobe) to speed up mass attachment (arch
    bits to come later).
 
  - Add unstable conntrack lookup helpers for BPF by using the BPF
    kfunc infra.
 
  - Allow cgroup BPF progs to return custom errors to user space.
 
  - Add support for AF_UNIX iterator batching.
 
  - Allow iterator programs to use sleepable helpers.
 
  - Support JIT of add, and, or, xor and xchg atomic ops on arm64.
 
  - Add BTFGen support to bpftool which allows to use CO-RE in kernels
    without BTF info.
 
  - Large number of libbpf API improvements, cleanups and deprecations.
 
 Protocols
 ---------
 
  - Micro-optimize UDPv6 Tx, gaining up to 5% in test on dummy netdev.
 
  - Adjust TSO packet sizes based on min_rtt, allowing very low latency
    links (data centers) to always send full-sized TSO super-frames.
 
  - Make IPv6 flow label changes (AKA hash rethink) more configurable,
    via sysctl and setsockopt. Distinguish between server and client
    behavior.
 
  - VxLAN support to "collect metadata" devices to terminate only
    configured VNIs. This is similar to VLAN filtering in the bridge.
 
  - Support inserting IPv6 IOAM information to a fraction of frames.
 
  - Add protocol attribute to IP addresses to allow identifying where
    given address comes from (kernel-generated, DHCP etc.)
 
  - Support setting socket and IPv6 options via cmsg on ping6 sockets.
 
  - Reject mis-use of ECN bits in IP headers as part of DSCP/TOS.
    Define dscp_t and stop taking ECN bits into account in fib-rules.
 
  - Add support for locked bridge ports (for 802.1X).
 
  - tun: support NAPI for packets received from batched XDP buffs,
    doubling the performance in some scenarios.
 
  - IPv6 extension header handling in Open vSwitch.
 
  - Support IPv6 control message load balancing in bonding, prevent
    neighbor solicitation and advertisement from using the wrong port.
    Support NS/NA monitor selection similar to existing ARP monitor.
 
  - SMC
    - improve performance with TCP_CORK and sendfile()
    - support auto-corking
    - support TCP_NODELAY
 
  - MCTP (Management Component Transport Protocol)
    - add user space tag control interface
    - I2C binding driver (as specified by DMTF DSP0237)
 
  - Multi-BSSID beacon handling in AP mode for WiFi.
 
  - Bluetooth:
    - handle MSFT Monitor Device Event
    - add MGMT Adv Monitor Device Found/Lost events
 
  - Multi-Path TCP:
    - add support for the SO_SNDTIMEO socket option
    - lots of selftest cleanups and improvements
 
  - Increase the max PDU size in CAN ISOTP to 64 kB.
 
 Driver API
 ----------
 
  - Add HW counters for SW netdevs, a mechanism for devices which
    offload packet forwarding to report packet statistics back to
    software interfaces such as tunnels.
 
  - Select the default NIC queue count as a fraction of number of
    physical CPU cores, instead of hard-coding to 8.
 
  - Expose devlink instance locks to drivers. Allow device layer of
    drivers to use that lock directly instead of creating their own
    which always runs into ordering issues in devlink callbacks.
 
  - Add header/data split indication to guide user space enabling
    of TCP zero-copy Rx.
 
  - Allow configuring completion queue event size.
 
  - Refactor page_pool to enable fragmenting after allocation.
 
  - Add allocation and page reuse statistics to page_pool.
 
  - Improve Multiple Spanning Trees support in the bridge to allow
    reuse of topologies across VLANs, saving HW resources in switches.
 
  - DSA (Distributed Switch Architecture):
    - replay and offload of host VLAN entries
    - offload of static and local FDB entries on LAG interfaces
    - FDB isolation and unicast filtering

bf2b83425b net: mv643xx_eth: use platform_get_irq() instead of platform_get_resource()
It is not recommened to use platform_get_resource(pdev, IORESOURCE_IRQ)
for requesting IRQ's resources any more, as they can be not ready yet in
case of DT-booting.

platform_get_irq() instead is a recommended way for getting IRQ even if
it was not retrieved earlier.

It also makes code simpler because we're getting "int" value right away
and no conversion from resource to int is required.

Obtaining a MAC address may be deferred in cases when the MAC is stored
in an NVMEM block, for example, and it may not be ready upon the first
retrieval attempt and return EPROBE_DEFER.

It is also possible that a port that does not rely on NVMEM has been
already created when getting the defer request. Thus, also the resources
allocated previously must be freed when doing a roll-back.

6426fc3aba octeontx2-af: cn10k: add workaround for ptp errata
This patch adds workaround for PTP errata given below.

1. At the time of 1 sec rollover of nano-second counter,
   the nano-second counter is set to 0. However, it should
   be set to (existing counter_value - 10^9). This leads to
   an accumulating error in the timestamp value with each sec
   rollover.
2. Additionally, the nano-second counter currently is rolling
   over at 'h3B9A_C9FF. It should roll over at 'h3B9A_CA00.

The workaround for issue #1 is to speed up the ptp clock by
adjusting PTP_CLOCK_COMP register to the desired value to
compensate for the nanoseconds lost per each second.

The workaround for issue #2 is to slow down the ptp clock
such that the rollover occurs at ~1sec.

74c1b2338e octeontx2-pf: cn10k: add support for new ptp timestamp format
The cn10k hardware ptp timestamp format has been modified primarily
to support 1-step ptp clock. The 64-bit timestamp used by hardware is
split into two 32-bit fields, the upper one holds seconds, the lower
one nanoseconds. A new register (PTP_CLOCK_SEC) has been added that
returns the current seconds value. The nanoseconds register PTP_CLOCK_HI
resets after every second. The cn10k RPM block provides Rx/Tx timestamps
to the NIX block using the new timestamp format. The software can read
the current timestamp in nanoseconds by reading both PTP_CLOCK_SEC &
PTP_CLOCK_HI registers.

This patch provides support for new timestamp format.

5224f79096 treewide: Replace zero-length arrays with flexible-array members
There is a regular need in the kernel to provide a way to declare
having a dynamically sized set of trailing elements in a structure.
Kernel code should always use “flexible array members”[1] for these
cases. The older style of one-element or zero-length arrays should
no longer be used[2].

This code was transformed with the help of Coccinelle:
(next-20220214$ spatch --jobs $(getconf _NPROCESSORS_ONLN) --sp-file script.cocci --include-headers --dir . > output.patch)

@@
identifier S, member, array;
type T1, T2;
@@

struct S {
  ...
  T1 member;
  T2 array[
- 0
  ];
};

UAPI and wireless changes were intentionally excluded from this patch
and will be sent out separately.

8e67558177 octeontx2-pf: PFC config support with DCBx
Data centric bridging designed to eliminate packet loss due to
queue overflow by adding enhancements to ethernet network such as
proprity flow control etc. This patch adds support for management
of Priority flow control(PFC) on Octeontx2 and CN10K interfaces.

To enable PFC for all priorities
	dcb pfc set dev eth0 prio-pfc all:on/off

To enable PFC on selected priorites
	dcb pfc set dev eth0 prio-pfc 0:on/off 1:on/off ..7:on/off

With the ntuple commands user can map Priority to receive queues.
On queue overflow NIX will assert backpressure such that PFC pause frames
are genarated with mapped priority.

To map priority 7 to Queue 1
ethtool -U eth0 flow-type ether dst xx:xx:xx:xx:xx:xx vlan 0xe00a
m 0x1fff  queue 1

bf25146a55 bpf: add frags support to the bpf_xdp_adjust_tail() API
This change adds support for tail growing and shrinking for XDP frags.

When called on a non-linear packet with a grow request, it will work
on the last fragment of the packet. So the maximum grow size is the
last fragments tailroom, i.e. no new buffer will be allocated.
A XDP frags capable driver is expected to set frag_size in xdp_rxq_info
data structure to notify the XDP core the fragment size.
frag_size set to 0 is interpreted by the XDP core as tail growing is
not allowed.
Introduce __xdp_rxq_info_reg utility routine to initialize frag_size field.

When shrinking, it will work from the last fragment, all the way down to
the base buffer depending on the shrinking size. It's important to mention
that once you shrink down the fragment(s) are freed, so you can not grow
again to the original size.

a8db854be2 octeontx2-pf: Forward error codes to VF
PF forwards its VF messages to AF and corresponding
replies from AF to VF. AF sets proper error code in the
replies after processing message requests. Currently PF
checks the error codes in replies and sends invalid
message to VF. This way VF lacks the information of
error code set by AF for its messages. This patch
changes that such that PF simply forwards AF replies
so that VF can handle error codes.

Add prestera_router_hw.c. This file contains functions, which track HW
objects relations and links. This include implicity creation of objects,
that needed by requested one and implicity removing of objects, which
reference counter is became zero.

We need this layer, because kernel callbacks not always mapped to
creation of single HW object. So let it be two different layers - one
for subscribing and parsing kernel structures, and another
(prestera_router_hw.c) for HW objects relations tracking.

There is two types of objects on router_hw layer:
 - Explicit objects (rif_entry) : created by higher layer.
 - Implicit objects (vr) : created on demand by explicit objects.

604ba23090 net: prestera: flower template support
Add user template explicit support. At this moment, max
TCAM rule size is utilized for all rules, doesn't matter
which and how much flower matches are provided by user. It
means that some of TCAM space is wasted, which impacts
the number of filters that can be offloaded.

Introducing the template, allows to have more HW offloaded
filters by specifying the template explicitly.

Example:
  tc qd add dev PORT clsact
  tc chain add dev PORT ingress protocol ip \
    flower dst_ip 0.0.0.0/16
  tc filter add dev PORT ingress protocol ip \
    flower skip_sw dst_ip 1.2.3.4/16 action drop

NOTE: chain 0 is the default chain id for "tc chain" & "tc filter"
      command, so it is omitted in the example above.

This patch adds only template support for default chain 0 suppoerted
by prestera driver at this moment. Chains are not supported yet,
and will be added later.

9c9211a3fc net_tstamp: add new flag HWTSTAMP_FLAG_BONDED_PHC_INDEX
Since commit 94dd016ae5 ("bond: pass get_ts_info and SIOC[SG]HWTSTAMP
ioctl to active device") the user could get bond active interface's
PHC index directly. But when there is a failover, the bond active
interface will change, thus the PHC index is also changed. This may
break the user's program if they did not update the PHC timely.

This patch adds a new hwtstamp_config flag HWTSTAMP_FLAG_BONDED_PHC_INDEX.
When the user wants to get the bond active interface's PHC, they need to
add this flag and be aware the PHC index may be changed.

With the new flag. All flag checks in current drivers are removed. Only
the checking in net_hwtstamp_validate() is kept.

a50e659b2a net: mvpp2: fix XDP rx queues registering
The registration of XDP queue information is incorrect because the
RX queue id we use is invalid. When port->id == 0 it appears to works
as expected yet it's no longer the case when port->id != 0.

The problem arised while using a recent kernel version on the
MACCHIATOBin. This board has several ports:
 * eth0 and eth1 are 10Gbps interfaces ; both ports has port->id == 0;
 * eth2 is a 1Gbps interface with port->id != 0.

Code from xdp-tutorial (more specifically advanced03-AF_XDP) was used
to test packet capture and injection on all these interfaces. The XDP
kernel was simplified to:

	SEC("xdp_sock")
	int xdp_sock_prog(struct xdp_md *ctx)
	{
		int index = ctx->rx_queue_index;

		/* A set entry here means that the correspnding queue_id
		* has an active AF_XDP socket bound to it. */
		if (bpf_map_lookup_elem(&xsks_map, &index))
			return bpf_redirect_map(&xsks_map, index, 0);

		return XDP_PASS;
	}

Starting the program using:

	./af_xdp_user -d DEV

Gives the following result:

 * eth0 : ok
 * eth1 : ok
 * eth2 : no capture, no injection

Investigating the issue shows that XDP rx queues for eth2 are wrong:
XDP expects their id to be in the range [0..3] but we found them to be
in the range [32..35].

Trying to force rx queue ids using:

	./af_xdp_user -d eth2 -Q 32

fails as expected (we shall not have more than 4 queues).

When we register the XDP rx queue information (using
xdp_rxq_info_reg() in function mvpp2_rxq_init()) we tell it to use
rxq->id as the queue id. This value is computed as:

	rxq->id = port->id * max_rxq_count + queue_id

where max_rxq_count depends on the device version. In the MACCHIATOBin
case, this value is 32, meaning that rx queues on eth2 are numbered
from 32 to 35 - there are four of them.

Clearly, this is not the per-port queue id that XDP is expecting:
it wants a value in the range [0..3]. It shall directly use queue_id
which is stored in rxq->logic_rxq -- so let's use that value instead.

rxq->id is left untouched ; its value is indeed valid but it should
not be used in this context.

This is consistent with the remaining part of the code in
mvpp2_rxq_init().

With this change, packet capture is working as expected on all the
MACCHIATOBin ports.

e07a097b49 octeontx2-af: Fix a memleak bug in rvu_mbox_init()
In rvu_mbox_init(), mbox_regions is not freed or passed out
under the switch-default region, which could lead to a memory leak.

Fix this bug by changing 'return err' to 'goto free_regions'.

This bug was found by a static analyzer. The analysis employs
differential checking to identify inconsistent security operations
(e.g., checks or kfrees) between two code paths and confirms that the
inconsistent operations are not recovered in the current function or
the callers, so they constitute bugs.

Note that, as a bug found by static analysis, it can be a false
positive or hard to trigger. Multiple researchers have cross-reviewed
the bug.

Builds with CONFIG_OCTEONTX2_AF=y show no new warnings,
and our static analyzer no longer warns about this code.

a280ef90af octeontx2-af: debugfs: don't corrupt user memory
The user supplies the "count" value to say how big its read buffer is.
The rvu_dbg_lmtst_map_table_display() function does not take the "count"
into account but instead just copies the whole table, potentially
corrupting the user's data.

Introduce the "ret" variable to store how many bytes we can copy.  Also
I changed the type of "off" to size_t to make using min() simpler.

bb7bbb6e36 net: marvell: mvpp2: Fix wrong SerDes reconfiguration order
Commit bfe301ebbc ("net: mvpp2: convert to use
mac_prepare()/mac_finish()") introduced a bug wherein it leaves the MAC
RESET register asserted after mac_finish(), due to wrong order of
function calls.

Before it was:
  .mac_config()
    mvpp22_mode_reconfigure()
      assert reset
    mvpp2_xlg_config()
      deassert reset

Now it is:
  .mac_prepare()
  .mac_config()
    mvpp2_xlg_config()
      deassert reset
  .mac_finish()
    mvpp2_xlg_config()
      assert reset

Obviously this is wrong.

This bug is triggered when phylink tries to change the PHY interface
mode from a GMAC mode (sgmii, 1000base-x, 2500base-x) to XLG mode
(10gbase-r, xaui). The XLG mode does not work since reset is left
asserted. Only after
  ifconfig down && ifconfig up
is called will the XLG mode work.

Move the call to mvpp22_mode_reconfigure() to .mac_prepare()
implementation. Since some of the subsequent functions need to know
whether the interface is being changed, we unfortunately also need to
pass around the new interface mode before setting port->phy_interface.

236f57fe1b net: marvell: prestera: Add explicit padding
On m68k:

    In function ‘prestera_hw_build_tests’,
	inlined from ‘prestera_hw_switch_init’ at drivers/net/ethernet/marvell/prestera/prestera_hw.c:788:2:
    ././include/linux/compiler_types.h:335:38: error: call to ‘__compiletime_assert_345’ declared with attribute error: BUILD_BUG_ON failed: sizeof(struct prestera_msg_switch_attr_req) != 16
    ...

The driver assumes structure members are naturally aligned, but does not
add explicit padding, thus breaking architectures where integral values
are not always naturally aligned (e.g. on m68k, __alignof(int) is 2, not
4).

bb5dbf2cc6 net: marvell: prestera: add firmware v4.0 support
Add firmware (FW) version 4.0 support for Marvell Prestera
driver.

Major changes have been made to new v4.0 FW ABI to add support
of new features, introduce the stability of the FW ABI and ensure
better forward compatibility for the future driver vesrions.

Current v4.0 FW feature set support does not expect any changes
to ABI, as it was defined and tested through long period of time.
The ABI may be extended in case of new features, but it will not
break the backward compatibility.

ABI major changes done in v4.0:
- L1 ABI, where MAC and PHY API configuration are split.
- ACL has been split to low-level TCAM and Counters ABI
  to provide more HW ACL capabilities for future driver
  versions.

To support backward support, the addition compatibility layer is
required in the driver which will have two different codebase under
"if FW-VER elif FW-VER else" conditions that will be removed
in the future anyway, So, the idea was to break backward support
and focus on more stable FW instead of supporting old version
with very minimal and limited set of features/capabilities.

Improve FW msg validation:
 * Use __le64, __le32, __le16 types in msg to/from FW to
   catch endian mismatch by sparse.
 * Use BUILD_BUG_ON for structures sent/recv to/from FW.

0daa55d033 octeontx2-af: cn10k: debugfs for dumping LMTST map table
CN10k SoCs use atomic stores of up to 128 bytes to submit
packets/instructions into co-processor cores. The enqueueing is performed
using Large Memory Transaction Store (LMTST) operations. They allow for
lockless enqueue operations - i.e., two different CPU cores can submit
instructions to the same queue without needing to lock the queue or
synchronize their accesses.

This patch implements a new debugfs entry for dumping LMTST map
table present on CN10K, as this might be very useful to debug any issue
in case of shared LMTST region among multiple pci functions.

e77bcdd1f6 octeontx2-af: Display all enabled PF VF rsrc_alloc entries.
Currently, we are using a fixed buffer size of length 2048 to display
rsrc_alloc output. As a result a maximum of 2048 characters of
rsrc_alloc output is displayed, which may lead sometimes to display only
partial output. This patch fixes this dependency on max limit of buffer
size and displays all PF VF entries.

Each column of the debugfs entry "rsrc_alloc" uses a fixed width of 12
characters to print the list of LFs of each block for a PF/VF. If the
length of list of LFs of a block exceeds this fixed width then the list
gets truncated and displays only a part of the list. This patch fixes
this by using the maximum possible length of list of LFs among all
blocks of all PFs and VFs entries as the width size.

ld.lld: error: undefined symbol: __this_module

Move the otx2_ptp.c code into a separate module that gets built for
both configurations, making it built-in if at least one of the other
two is built-in.

149f3b73cb octeontx2-af: Add support to flush full CPT CTX cache
Adds support to flush or invalidate CPT CTX entries as part of FLR
and also provides a mailbox to flush CPT CTX entries in case of
graceful exit.
This patch also adds support for AF -> CPT PF uplink mailbox messages
and adds a new mbox message to submit a CPT instruction from AF.

7054d39ccf octeontx2-af: Perform cpt lf teardown in non FLR path
Perform CPT LF teardown in non FLR path as well via cpt_lf_free()
Currently CPT LF teardown and reset sequence is only
done when FLR is handled with CPT LF still attached.

This patch also fixes cpt_lf_alloc() to set EXEC_LDWB in
CPT_AF_LFX_CTL2 when being completely overwritten as that is
the default value and is better for performance.

766607570b ethernet: constify references to netdev->dev_addr in drivers
This big patch sprinkles const on local variables and
function arguments which may refer to netdev->dev_addr.

Commit 406f42fa0d ("net-next: When a bond have a massive amount
of VLANs...") introduced a rbtree for faster Ethernet address look
up. To maintain netdev->dev_addr in this tree we need to make all
the writes to it got through appropriate helpers.

Some of the changes here are not strictly required - const
is sometimes cast off but pointer is not used for writing.
It seems like it's still better to add the const in case
the code changes later or relevant -W flags get enabled
for the build.

No functional changes.

0182d0788c octeontx2-pf: Simplify the receive buffer size calculation
This patch separates the logic of configuring hardware
maximum transmit frame size and receive frame size.
This simplifies the logic to calculate receive buffer
size and using cqe descriptor of different size.
Also additional size of skb_shared_info structure is
allocated for each receive buffer pointer given to
hardware which is not necessary. Hence change the
size calculation to remove the size of
skb_shared_info. Add a check for array out of
bounds while adding fragments to the network stack.

8017c4d817 eth: fwnode: change the return type of mac address helpers
fwnode_get_mac_address() and device_get_mac_address()
return a pointer to the buffer that was passed to them
on success or NULL on failure. None of the callers
care about the actual value, only if it's NULL or not.

These semantics differ from of_get_mac_address() which
returns an int so to avoid confusion make the device
helpers return an errno.
