vxlan: Pull inner IP header in vxlan_xmit_one().
Ensure the inner IP header is part of the skb's linear data before
setting old_iph. Otherwise, on a non-linear skb, old_iph could point
outside of the packet data.
Unlike classical VXLAN, which always encapsulates Ethernet packets,
VXLAN-GPE can transport IP packets directly. In that case, we need to
look at skb->protocol to figure out if an Ethernet header is present.

mlxsw: spectrum_buffers: Fix memory corruptions on Spectrum-4 systems
The following two shared buffer operations make use of the Shared Buffer
Status Register (SBSR):
# devlink sb occupancy snapshot pci/0000:01:00.0
# devlink sb occupancy clearmax pci/0000:01:00.0
The register has two masks of 256 bits to denote on which ingress /
egress ports the register should operate on. Spectrum-4 has more than
256 ports, so the register was extended by cited commit with a new
'port_page' field.
However, when filling the register's payload, the driver specifies the
ports as absolute numbers and not relative to the first port of the port
page, resulting in memory corruptions [1].
Fix by specifying the ports relative to the first port of the port page.

mlxsw: pci: Fix driver initialization with Spectrum-4
Cited commit added support for a new reset flow ("all reset") which is
deeper than the existing reset flow ("software reset") and allows the
device's PCI firmware to be upgraded.
In the new flow the driver first tells the firmware that "all reset" is
required by issuing a new reset command (i.e., MRSR.command=6) and then
triggers the reset by having the PCI core issue a secondary bus reset
(SBR).
However, due to a race condition in the device's firmware the device is
not always able to recover from this reset, resulting in initialization
failures [1].
New firmware versions include a fix for the bug and advertise it using a
new capability bit in the Management Capabilities Mask (MCAM) register.
Avoid initialization failures by reading the new capability bit and
triggering the new reset flow only if the bit is set. If the bit is not
set, trigger a normal PCI hot reset by skipping the call to the
Management Reset and Shutdown Register (MRSR).
Normal PCI hot reset is weaker than "all reset", but it results in a
fully operational driver and allows users to flash a new firmware, if
they want to.

selftest: af_unix: Add Kconfig file.
diag_uid selftest failed on NIPA where the received nlmsg_type is
NLMSG_ERROR [0] because CONFIG_UNIX_DIAG is not set [1] by default
and sock_diag_lock_handler() failed to load the module.
# # Starting 2 tests from 2 test cases.
# # RUN diag_uid.uid.1 ...
# # diag_uid.c:159:1:Expected nlh->nlmsg_type (2) == SOCK_DIAG_BY_FAMILY (20)
# # 1: Test terminated by assertion
# # FAIL diag_uid.uid.1
# not ok 1 diag_uid.uid.1
Let's add all AF_UNIX Kconfig to the config file under af_unix dir
so that NIPA consumes it.

ionic: fix kernel panic due to multi-buffer handling
Currently, the ionic_run_xdp() doesn't handle multi-buffer packets
properly for XDP_TX and XDP_REDIRECT.
When a jumbo frame is received, the ionic_run_xdp() first makes xdp
frame with all necessary pages in the rx descriptor.
And if the action is either XDP_TX or XDP_REDIRECT, it should unmap
dma-mapping and reset page pointer to NULL for all pages, not only the
first page.
But it doesn't for SG pages. So, SG pages unexpectedly will be reused.
It eventually causes kernel panic.

bonding: fix incorrect software timestamping report
The __ethtool_get_ts_info function returns directly if the device has a
get_ts_info() method. For bonding with an active slave, this works correctly
as we simply return the real device's timestamping information. However,
when there is no active slave, we only check the slave's TX software
timestamp information. We still need to set the phc index and RX timestamp
information manually. Otherwise, the result will be look like:
Time stamping parameters for bond0:
Capabilities:
software-transmit
PTP Hardware Clock: 0
Hardware Transmit Timestamp Modes: none
Hardware Receive Filter Modes: none
This issue does not affect VLAN or MACVLAN devices, as they only have one
downlink and can directly use the downlink's timestamping information.

Ilya found a failure in running check-kernel tests with at_groups=144 (144: conntrack - FTP SNAT orig tuple) in OVS repo. After his further investigation, the root cause is that the labels sent to userspace for related ct are incorrect. The labels for unconfirmed related ct should use its master's labels.

can: mcp251xfd: fix infinite loop when xmit fails
When the mcp251xfd_start_xmit() function fails, the driver stops
processing messages, and the interrupt routine does not return,
running indefinitely even after killing the running application.
Error messages:
[ 441.298819] mcp251xfd spi2.0 can0: ERROR in mcp251xfd_start_xmit: -16
[ 441.306498] mcp251xfd spi2.0 can0: Transmit Event FIFO buffer not empty. (seq=0x000017c7, tef_tail=0x000017cf, tef_head=0x000017d0, tx_head=0x000017d3).
... and repeat forever.
The issue can be triggered when multiple devices share the same SPI
interface. And there is concurrent access to the bus.
The problem occurs because tx_ring->head increments even if
mcp251xfd_start_xmit() fails. Consequently, the driver skips one TX
package while still expecting a response in
mcp251xfd_handle_tefif_one().
Resolve the issue by starting a workqueue to write the tx obj
synchronously if err = -EBUSY. In case of another error, decrement
tx_ring->head, remove skb from the echo stack, and drop the message.

net: can: j1939: enhanced error handling for tightly received RTS messages in xtp_rx_rts_session_new
This patch enhances error handling in scenarios with RTS (Request to
Send) messages arriving closely. It replaces the less informative WARN_ON_ONCE
backtraces with a new error handling method. This provides clearer error
messages and allows for the early termination of problematic sessions.
Previously, sessions were only released at the end of j1939_xtp_rx_rts().
Potentially this could be reproduced with something like:
testj1939 -r vcan0:0x80 &
while true; do
# send first RTS
cansend vcan0 18EC8090#1014000303002301;
# send second RTS
cansend vcan0 18EC8090#1014000303002301;
# send abort
cansend vcan0 18EC8090#ff00000000002301;

net: dsa: microchip: fix initial port flush problem
The very first flush in any port will flush all learned addresses in all
ports. This can be observed by unplugging the cable from one port while
additional ports are connected and dumping the fdb entries.
This problem is caused by the initially wrong value programmed to the
REG_SW_LUE_CTRL_1 register. Setting SW_FLUSH_STP_TABLE and
SW_FLUSH_MSTP_TABLE bits does not have an immediate effect. It is when
ksz9477_flush_dyn_mac_table() is called then the SW_FLUSH_STP_TABLE bit
takes effect and flushes all learned entries. After that call both bits
are reset and so the next port flush will not cause such problem again.

selftests: virtio_net: add forgotten config options
One may use tools/testing/selftests/drivers/net/virtio_net/config
for example for vng build command like this one:
$ vng -v -b -f tools/testing/selftests/drivers/net/virtio_net/config
In that case, the needed kernel config options are not turned on.
Add the missed kernel config options.

bnxt_en: Restore PTP tx_avail count in case of skb_pad() error
The current code only restores PTP tx_avail count when we get DMA
mapping errors. Fix it so that the PTP tx_avail count will be
restored for both DMA mapping errors and skb_pad() errors.
Otherwise PTP TX timestamp will not be available after a PTP
packet hits the skb_pad() error.

bnxt_en: Set TSO max segs on devices with limits
Firmware will now advertise a non-zero TSO max segments if the
device has a limit. 0 means no limit. The latest 5760X chip
(early revs) has a limit of 2047 that cannot be exceeded. If
exceeded, the chip will send out just a small number of segments.
Call netif_set_tso_max_segs() if the device has a limit.

ice: Fix VSI list rule with ICE_SW_LKUP_LAST type
Adding/updating VSI list rule, as well as allocating/freeing VSI list
resource are called several times with type ICE_SW_LKUP_LAST, which fails
because ice_update_vsi_list_rule() and ice_aq_alloc_free_vsi_list()
consider it invalid. Allow calling these functions with ICE_SW_LKUP_LAST.
This fixes at least one issue in switchdev mode, where the same rule with
different action cannot be added, e.g.:
tc filter add dev $PF1 ingress protocol arp prio 0 flower skip_sw \
dst_mac ff:ff:ff:ff:ff:ff action mirred egress redirect dev $VF1_PR
tc filter add dev $PF1 ingress protocol arp prio 0 flower skip_sw \

ipv6: bring NLM_DONE out to a separate recv() again
Commit under Fixes optimized the number of recv() calls needed during RTM_GETROUTE dumps, but we got multiple reports of applications hanging on recv() calls. Applications expect that a route dump will be terminated with a recv() reading an individual NLM_DONE message. Coalescing NLM_DONE is perfectly legal in netlink, but even tho reporters fixed the code in respective projects, chances are it will take time for those applications to get updated. So revert to old behavior (for now)? This is an IPv6 version of commit |

netfilter: ipset: Fix suspicious rcu_dereference_protected()
When destroying all sets, we are either in pernet exit phase or
are executing a "destroy all sets command" from userspace. The latter
was taken into account in ip_set_dereference() (nfnetlink mutex is held),
but the former was not. The patch adds the required check to
rcu_dereference_protected() in ip_set_dereference().

octeontx2-pf: Add error handling to VLAN unoffload handling
otx2_sq_append_skb makes used of __vlan_hwaccel_push_inside()
to unoffload VLANs - push them from skb meta data into skb data.
However, it omitts a check for __vlan_hwaccel_push_inside()
returning NULL.
Found by inspection based on [1] and [2].
Compile tested only.

Merge branch 'virtio_net-csum-xdp-fixes'
Heng Qi says: ==================== virtio_net: fixes for checksum offloading and XDP handling This series of patches aim to address two specific issues identified in the virtio_net driver related to checksum offloading and XDP processing of fully checksummed packets. The first patch corrects the handling of checksum offloading in the driver. The second patch addresses an issue where the XDP program had no trouble with fully checksummed packets. ==================== Signed-off-by: David S. Miller <davem@davemloft.net> |

virtio_net: fixing XDP for fully checksummed packets handling
The XDP program can't correctly handle partially checksummed
packets, but works fine with fully checksummed packets. If the
device has already validated fully checksummed packets, then
the driver doesn't need to re-validate them, saving CPU resources.
Additionally, the driver does not drop all partially checksummed
packets when VIRTIO_NET_F_GUEST_CSUM is not negotiated. This is
not a bug, as the driver has always done this.

virtio_net: checksum offloading handling fix
In virtio spec 0.95, VIRTIO_NET_F_GUEST_CSUM was designed to handle
partially checksummed packets, and the validation of fully checksummed
packets by the device is independent of VIRTIO_NET_F_GUEST_CSUM
negotiation. However, the specification erroneously stated:
"If VIRTIO_NET_F_GUEST_CSUM is not negotiated, the device MUST set flags
to zero and SHOULD supply a fully checksummed packet to the driver."
This statement is inaccurate because even without VIRTIO_NET_F_GUEST_CSUM
negotiation, the device can still set the VIRTIO_NET_HDR_F_DATA_VALID flag.
Essentially, the device can facilitate the validation of these packets'
checksums - a process known as RX checksum offloading - removing the need
for the driver to do so.
This scenario is currently not implemented in the driver and requires
correction. The necessary specification correction[1] has been made and
approved in the virtio TC vote.
