Yick Xie 680d11f6e5 udp: preserve the connected status if only UDP cmsg
If "udp_cmsg_send()" returned 0 (i.e. only UDP cmsg),
"connected" should not be set to 0. Otherwise it stops
the connected socket from using the cached route.

David Bauer f58f45c1e5 vxlan: drop packets from invalid src-address
The VXLAN driver currently does not check if the inner layer2
source-address is valid.

In case source-address snooping/learning is enabled, a entry in the FDB
for the invalid address is created with the layer3 address of the tunnel
endpoint.

If the frame happens to have a non-unicast address set, all this
non-unicast traffic is subsequently not flooded to the tunnel network
but sent to the learnt host in the FDB. To make matters worse, this FDB
entry does not expire.

Apply the same filtering for packets as it is done for bridges. This not
only drops these invalid packets but avoids them from being learnt into
the FDB.

Duanqiang Wen 69197dfc64 net: libwx: fix alloc msix vectors failed
driver needs queue msix vectors and one misc irq vector,
but only queue vectors need irq affinity.
when num_online_cpus is less than chip max msix vectors,
driver will acquire (num_online_cpus + 1) vecotrs, and
call pci_alloc_irq_vectors_affinity functions with affinity
params without setting pre_vectors or post_vectors, it will
cause return error code -ENOSPC.
Misc irq vector is vector 0, driver need to set affinity params
.pre_vectors = 1.

Siddharth Vadapalli c24cd679b0 net: ethernet: ti: am65-cpsw-nuss: cleanup DMA Channels before using them
The TX and RX DMA Channels used by the driver to exchange data with CPSW
are not guaranteed to be in a clean state during driver initialization.
The Bootloader could have used the same DMA Channels without cleaning them
up in the event of failure. Thus, reset and disable the DMA Channels to
ensure that they are in a clean state before using them.

Jose Ignacio Tornos Martinez 56f78615bc net: usb: ax88179_178a: avoid writing the mac address before first reading
After the commit d2689b6a86 ("net: usb: ax88179_178a: avoid two
consecutive device resets"), reset operation, in which the default mac
address from the device is read, is not executed from bind operation and
the random address, that is pregenerated just in case, is direclty written
the first time in the device, so the default one from the device is not
even read. This writing is not dangerous because is volatile and the
default mac address is not missed.

In order to avoid this and keep the simplification to have only one
reset and reduce the delays, restore the reset from bind operation and
remove the reset that is commanded from open operation. The behavior is
the same but everything is ready for usbnet_probe.

Tested with ASIX AX88179 USB Gigabit Ethernet devices.
Restore the old behavior for the rest of possible devices because I don't
have the hardware to test.

====================
Netfilter fixes for net

The following patchset contains Netfilter fixes for net:

Patch #1 amends a missing spot where the set iterator type is unset.
	 This is fixing a issue in the previous pull request.

Patch #2 fixes the delete set command abort path by restoring state
         of the elements. Reverse logic for the activate (abort) case
	 otherwise element state is not restored, this requires to move
	 the check for active/inactive elements to the set iterator
	 callback. From the deactivate path, toggle the next generation
	 bit and from the activate (abort) path, clear the next generation
	 bitmask.

Patch #3 skips elements already restored by delete set command from the
	 abort path in case there is a previous delete element command in
	 the batch. Check for the next generation bit just like it is done
	 via set iteration to restore maps.

R-Car M3N Salvator-XS board - this is the only R-Car board I currently
have access to.

Patches 2, 3 & 4 affect the GbEth code paths so have been tested on
RZ/G2L and RZ/G2UL SMARC EVK boards.

Changes v2->v3:
  * Incorporate feedback from Niklas and add Reviewed-by tag to patch
    "net: ravb: Count packets instead of descriptors in R-Car RX path".
Changes v1->v2:
  * Fixed typos in commit message of patch
    "net: ravb: Allow RX loop to move past DMA mapping errors".
  * Added Sergey's Reviewed-by tags.
  * Expanded Cc list as Patchwork complained that I had missed people.
  * Trimmed the call trace in accordance with the docs [1] in patch
    "net: ravb: Fix GbEth jumbo packet RX checksum handling".

Paul Barker 2e36c9fbc4 net: ravb: Fix RX byte accounting for jumbo packets
The RX byte accounting for jumbo packets was changed to fix a potential
use-after-free bug. However, that fix used the wrong variable and so
only accounted for the number of bytes in the final descriptor, not the
number of bytes in the whole packet.

To fix this, we can simply update our stats with the correct number of
bytes before calling napi_gro_receive().

Also rename pkt_len to desc_len in ravb_rx_gbeth() to avoid any future
confusion. The variable name pkt_len is correct in ravb_rx_rcar() as
that function does not handle packets spanning multiple descriptors.

Paul Barker a892493a34 net: ravb: Allow RX loop to move past DMA mapping errors
The RX loops in ravb_rx_gbeth() and ravb_rx_rcar() skip to the next loop
iteration if a zero-length descriptor is seen (indicating a DMA mapping
error). However, the current RX descriptor index `priv->cur_rx[q]` was
incremented at the end of the loop and so would not be incremented when
we skip to the next loop iteration. This would cause the loop to keep
seeing the same zero-length descriptor instead of moving on to the next
descriptor.

As the loop counter `i` still increments, the loop would eventually
terminate so there is no risk of being stuck here forever - but we
should still fix this to avoid wasting cycles.

To fix this, the RX descriptor index is incremented at the top of the
loop, in the for statement itself. The assignments of `entry` and `desc`
are brought into the loop to avoid the need for duplication.

Paul Barker def52db470 net: ravb: Count packets instead of descriptors in R-Car RX path
The units of "work done" in the RX path should be packets instead of
descriptors.

Descriptors which are used by the hardware to record error conditions or
are empty in the case of a DMA mapping error should not count towards
our RX work budget.

Also make the limit variable unsigned as it can never be negative.

We fix this by adding an owner field (CPU id) to struct Qdisc set after
root qdisc is entered. When the softirq enters it a second time, if the
qdisc owner is the same CPU, the packet is dropped to break the loop.

Pablo Neira Ayuso 86a1471d7c netfilter: nf_tables: fix memleak in map from abort path
The delete set command does not rely on the transaction object for
element removal, therefore, a combination of delete element + delete set
from the abort path could result in restoring twice the refcount of the
mapping.

Check for inactive element in the next generation for the delete element
command in the abort path, skip restoring state if next generation bit
has been already cleared. This is similar to the activate logic using
the set walk iterator.

Pablo Neira Ayuso e79b47a861 netfilter: nf_tables: restore set elements when delete set fails
From abort path, nft_mapelem_activate() needs to restore refcounters to
the original state. Currently, it uses the set->ops->walk() to iterate
over these set elements. The existing set iterator skips inactive
elements in the next generation, this does not work from the abort path
to restore the original state since it has to skip active elements
instead (not inactive ones).

This patch moves the check for inactive elements to the set iterator
callback, then it reverses the logic for the .activate case which
needs to skip active elements.

Toggle next generation bit for elements when delete set command is
invoked and call nft_clear() from .activate (abort) path to restore the
next generation bit.

The splat below shows an object in mappings memleak:

Gerd Bayer 83781384a9 s390/ism: Properly fix receive message buffer allocation
Since [1], dma_alloc_coherent() does not accept requests for GFP_COMP
anymore, even on archs that may be able to fulfill this. Functionality that
relied on the receive buffer being a compound page broke at that point:
The SMC-D protocol, that utilizes the ism device driver, passes receive
buffers to the splice processor in a struct splice_pipe_desc with a
single entry list of struct pages. As the buffer is no longer a compound
page, the splice processor now rejects requests to handle more than a
page worth of data.

Replace dma_alloc_coherent() and allocate a buffer with folio_alloc and
create a DMA map for it with dma_map_page(). Since only receive buffers
on ISM devices use DMA, qualify the mapping as FROM_DEVICE.
Since ISM devices are available on arch s390, only, and on that arch all
DMA is coherent, there is no need to introduce and export some kind of
dma_sync_to_cpu() method to be called by the SMC-D protocol layer.

Analogously, replace dma_free_coherent by a two step dma_unmap_page,
then folio_put to free the receive buffer.

Jason A. Donenfeld e871abcda3 random: handle creditable entropy from atomic process context
The entropy accounting changes a static key when the RNG has
initialized, since it only ever initializes once. Static key changes,
however, cannot be made from atomic context, so depending on where the
last creditable entropy comes from, the static key change might need to
be deferred to a worker.

Previously the code used the execute_in_process_context() helper
function, which accounts for whether or not the caller is
in_interrupt(). However, that doesn't account for the case where the
caller is actually in process context but is holding a spinlock.

This turned out to be the case with input_handle_event() in
drivers/input/input.c contributing entropy:

  [<ffffffd613a81310>] input_event+0x6c/0x98

According to Guoyong, it's not really possible to refactor the various
drivers to never hold a spinlock there. And in_atomic() isn't reliable.

So, rather than trying to be too fancy, just punt the change in the
static key to a workqueue always. There's basically no drawback of doing
this, as the code already needed to account for the static key not
changing immediately, and given that it's just an optimization, there's
not exactly a hurry to change the static key right away, so deferal is
fine.

The "MT7988A Wi-Fi 7 Generation Router Platform: Datasheet (Open Version)
v0.1" document shows bits 16 to 18 as the MIRROR_PORT field of the CPU
forward control register. Currently, the MT7530 DSA subdriver configures
bits 0 to 2 of the CPU forward control register which breaks the port
mirroring feature for the MT7988 SoC switch.

Fix this by using the MT7531_MIRROR_PORT_GET() and MT7531_MIRROR_PORT_SET()
macros which utilise the correct bits.

The check for flags is done to not pass empty lookups to adding switch
rule functions. Since metadata is always added to lookups there is no
need to check against the flag.

It is also fixing the problem with such rule:
$ tc filter add dev gtp_dev ingress protocol ip prio 0 flower \
	enc_dst_port 2123 action drop
Switch block in case of GTP can't parse the destination port, because it
should always be set to GTP specific value. The same with ethertype. The
result is that there is no other matching criteria than GTP tunnel. In
this case flags is 0, rule can't be added only because of defensive
check against flags.

In case of traffic going from the VF (so ingress for port representor)
source VSI should be consider during packet classification. It is
needed for hardware to not match packets from different ports with
filters added on other port.

It is only for "from VF" traffic, because other traffic direction
doesn't have source VSI.

Set correct ::src_vsi in rule_info to pass it to the hardware filter.

For example this rule should drop only ipv4 packets from eth10, not from
the others VF PRs. It is needed to check source VSI in this case.

====================
net: stmmac: Fix MAC-capabilities procedure

The series got born as a result of the discussions around the recent
Yanteng' series adding the Loongson LS7A1000, LS2K1000, LS7A2000, LS2K2000
MACs support:
Link: https://lore.kernel.org/netdev/fu3f6uoakylnb6eijllakeu5i4okcyqq7sfafhp5efaocbsrwe@w74xe7gb6x7p

In particular the Yanteng' patchset needed to implement the Loongson
MAC-specific constraints applied to the link speed and link duplex mode.
As a result of the discussion with Russel the next preliminary patch was
born:
Link: https://lore.kernel.org/netdev/df31e8bcf74b3b4ddb7ddf5a1c371390f16a2ad5.1712917541.git.siyanteng@loongson.cn

The patch above was a temporal solution utilized by Yanteng for further
developments and to move on with the on-going review. This patchset is a
refactored version of that single patch with formatting required for the
fixes patches.

In particular the series starts with fixing the half-duplex-less
constraint currently applied for all IP-cores. In fact it's specific for
the DW QoS Eth only (DW GMAC v4.x/v5.x).

The next patch fixes the MAC-capabilities setting up during the active
Tx/Rx queues re-initialization procedure. Particularly the procedure
missed the max-speed limit thus possibly activating speeds prohibited on
the respective platforms.

Third patch fixes the incorrect MAC-capabilities initialization for DW
MAC100, DW XGMAC and DW XLGMAC devices by moving the correct
initialization to the IP-core specific setup() methods.

That's it for now. Thanks for review and testing in advance.

Meanwhile what is currently implemented defines 10/100/1000 link speeds
for all IP-cores, which is definitely incorrect for DW MAC100, DW XGMAC
and DW XLGMAC devices.

Seeing the flow-control is implemented as a callback for each MAC IP-core
(see dwmac100_flow_ctrl(), dwmac1000_flow_ctrl(), sun8i_dwmac_flow_ctrl(),
etc) and since the MAC-specific setup() method is supposed to be called
for each available DW MAC-based device, the capabilities initialization
can be freely moved to these setup() functions, thus correctly setting up
the MAC-capabilities for each IP-core (including the Allwinner Sun8i). A
new stmmac_link::caps field was specifically introduced for that so to
have all link-specific info preserved in a single structure.

Note the suggested change fixes three earlier commits at a time. The
commit 5b0d7d7da6 ("net: stmmac: Add the missing speeds that XGMAC
supports") permitted the 10-100 link speeds and 1G half-duplex mode for DW
XGMAC IP-core even though it doesn't support them. The commit df7699c70c
("net: stmmac: Do not cut down 1G modes") incorrectly added the MAC1000
capability to the DW MAC100 IP-core. Similarly to the DW XGMAC the commit
8a880936e9 ("net: stmmac: Add XLGMII support") incorrectly permitted the
10-100 link speeds and 1G half-duplex mode for DW XLGMAC IP-core.

Serge Semin 59c3d6ca6c net: stmmac: Fix max-speed being ignored on queue re-init
It's possible to have the maximum link speed being artificially limited on
the platform-specific basis. It's done either by setting up the
plat_stmmacenet_data::max_speed field or by specifying the "max-speed"
DT-property. In such cases it's required that any specific
MAC-capabilities re-initializations would take the limit into account. In
particular the link speed capabilities may change during the number of
active Tx/Rx queues re-initialization. But the currently implemented
procedure doesn't take the speed limit into account.

Fix that by calling phylink_limit_mac_speed() in the
stmmac_reinit_queues() method if the speed limitation was required in the
same way as it's done in the stmmac_phy_setup() function.

Serge Semin 0ebd96f5da net: stmmac: Apply half-duplex-less constraint for DW QoS Eth only
There are three DW MAC IP-cores which can have the multiple Tx/Rx queues
enabled:
DW GMAC v3.7+ with AV feature,
DW QoS Eth v4.x/v5.x,
DW XGMAC/XLGMAC
Based on the respective HW databooks, only the DW QoS Eth IP-core doesn't
support the half-duplex link mode in case if more than one queues enabled:

"In multiple queue/channel configurations, for half-duplex operation,
enable only the Q0/CH0 on Tx and Rx. For single queue/channel in
full-duplex operation, any queue/channel can be enabled."

The rest of the IP-cores don't have such constraint. Thus in order to have
the constraint applied for the DW QoS Eth MACs only, let's move the it'
implementation to the respective MAC-capabilities getter and make sure the
getter is called in the queues re-init procedure.
