7ea4376b39 net/mlx5e: Remove redundant tstamp pointer from channel structures
Remove the tstamp pointer field from mlx5e_channel, mlx5e_ptp, and
mlx5e_trap structures, since it was only used to reference the tstamp
field in the priv structure. Instead, directly use the tstamp field
from priv when initializing RQ structures.

Also remove the unused hwtstamp_config field from mlx5_clock structure
as part of the cleanup.

54133f9b4b net: mana: Support HW link state events
Handle the NIC hardware link state events received from the HW
channel, then set the proper link state accordingly.

And, add a feature bit, GDMA_DRV_CAP_FLAG_1_HW_VPORT_LINK_AWARE,
to inform the NIC hardware this handler exists.

Our MANA NIC only sends out the link state down/up messages
when we need to let the VM rerun DHCP client and change IP
address. So, add netif_carrier_on() in the probe(), let the NIC
show the right initial state in /sys/class/net/ethX/operstate.

0d0eb18642 cxgb4: flower: add support for fragmentation
This patch adds support for matching fragmented packets in tc flower
filters.

Previously, commit 93a8540aac ("cxgb4: flower: validate control flags")
added a check using flow_rule_match_has_control_flags() to reject
any rules with control flags, as the driver did not support
fragmentation at that time.

Now, with this patch, support for FLOW_DIS_IS_FRAGMENT is added:
- The driver checks for control flags using
  flow_rule_is_supp_control_flags(), as recommended in
  commit d11e631194 ("flow_offload: add control flag checking helpers").
- If the fragmentation flag is present, the driver sets `fs->val.frag` and
  `fs->mask.frag` accordingly in the filter specification.

Since fragmentation is now supported, the earlier check that rejected all
control flags (flow_rule_match_has_control_flags()) has been removed.

ecca75ae5a selftests: drv-net: replace the nsim ring test with a drv-net one
We are trying to move away from netdevsim-only tests and towards
tests which can be run both against netdevsim and real drivers.

Replace the simple bash script we have for checking ethtool -g/-G
on netdevsim with a Python test tweaking those params as well
as channel count.

The new test is not exactly equivalent to the netdevsim one,
but real drivers don't often support random ring sizes,
let alone modifying max values via debugfs.

Halil Pasic says:

====================
net/smc: make wr buffer count configurable

The current value of SMC_WR_BUF_CNT is 16 which leads to heavy
contention on the wr_tx_wait workqueue of the SMC-R linkgroup and its
spinlock when many connections are competing for the work request
buffers. Currently up to 256 connections per linkgroup are supported.

To make things worse when finally a buffer becomes available and
smc_wr_tx_put_slot() signals the linkgroup's wr_tx_wait wq, because
WQ_FLAG_EXCLUSIVE is not used all the waiters get woken up, most of the
time a single one can proceed, and the rest is contending on the
spinlock of the wq to go to sleep again.

Addressing this by simply bumping SMC_WR_BUF_CNT to 256 was deemed
risky, because the large-ish physically continuous allocation could fail
and lead to TCP fall-backs. For reference see this discussion thread on
"[PATCH net-next] net/smc: increase SMC_WR_BUF_CNT" (in archive
https://lists.openwall.net/netdev/2024/11/05/186), which concludes with
the agreement to try to come up with something smarter, which is what
this series aims for.

Additionally if for some reason it is known that heavy contention is not
to be expected going with something like 256 work request buffers is
wasteful. To address these concerns make the number of work requests
configurable, and introduce a back-off logic with handles -ENOMEM form
smc_wr_alloc_link_mem() gracefully.

8f736087e5 net/smc: handle -ENOMEM from smc_wr_alloc_link_mem gracefully
Currently if a -ENOMEM from smc_wr_alloc_link_mem() is handled by
giving up and going the way of a TCP fallback. This was reasonable
before the sizes of the allocations there were compile time constants
and reasonably small. But now those are actually configurable.

So instead of giving up, keep retrying with half of the requested size
unless we dip below the old static sizes -- then give up! In terms of
numbers that means we give up when it is certain that we at best would
end up allocating less than 16 send WR buffers or less than 48 recv WR
buffers. This is to avoid regressions due to having fewer buffers
compared the static values of the past.

Please note that SMC-R is supposed to be an optimisation over TCP, and
falling back to TCP is superior to establishing an SMC connection that
is going to perform worse. If the memory allocation fails (and we
propagate -ENOMEM), we fall back to TCP.

Preserve (modulo truncation) the ratio of send/recv WR buffer counts.

aef3cdb47b net/smc: make wr buffer count configurable
Think SMC_WR_BUF_CNT_SEND := SMC_WR_BUF_CNT used in send context and
SMC_WR_BUF_CNT_RECV := 3 * SMC_WR_BUF_CNT used in recv context. Those
get replaced with lgr->max_send_wr and lgr->max_recv_wr respective.

Please note that although with the default sysctl values
qp_attr.cap.max_send_wr ==  qp_attr.cap.max_recv_wr is maintained but
can not be assumed to be generally true any more. I see no downside to
that, but my confidence level is rather modest.

2b749f2576 netfilter: conntrack: disable 0 value for conntrack_max setting
Undocumented historical artifact inherited from ip_conntrack.

the kernel-internal upper limit on the hash chain lengths.

This feature makes no sense; users can just set
conntrack_max=2147483647 (INT_MAX).

Disallow a 0 value.  This will make it slightly easier to allow
per-netns constraints for this value in a future patch.

51e5ad549c net: sctp: fix KMSAN uninit-value in sctp_inq_pop
Fix an issue detected by syzbot:

KMSAN reported an uninitialized-value access in sctp_inq_pop
BUG: KMSAN: uninit-value in sctp_inq_pop

The issue is actually caused by skb trimming via sk_filter() in sctp_rcv().
In the reproducer, skb->len becomes 1 after sk_filter(), which bypassed the
original check:

        if (skb->len < sizeof(struct sctphdr) + sizeof(struct sctp_chunkhdr) +
                       skb_transport_offset(skb))
To handle this safely, a new check should be performed after sk_filter().

ea7d0d60eb Merge branch 'add-cn20k-nix-and-npa-contexts'
Subbaraya Sundeep says:

====================
Add CN20K NIX and NPA contexts

The hardware contexts of blocks NIX and NPA in CN20K silicon are
different than that of previous silicons CN10K and CN9XK. This
patchset adds the new contexts of CN20K in AF and PF drivers.
A new mailbox for enqueuing contexts to hardware is added.

Patch 1 simplifies context writing and reading by using max context
size supported by hardware instead of using each context size.
Patch 2 and 3 adds NIX block contexts in AF driver and extends
debugfs to display those new contexts
Patch 4 and 5 adds NPA block contexts in AF driver and extends
debugfs to display those new contexts
Patch 6 omits NDC configuration since CN20K NPA does not use NDC
for caching its contexts
Patch 7 and 8 uses the new NIX and NPA contexts in PF/VF driver.
Patch 9, 10 and 11 are to support more bandwidth profiles present in
CN20K for RX ratelimiting and to display new profiles in debugfs

6a2108c780 net: devmem: refresh devmem TX dst in case of route invalidation
The zero-copy Device Memory (Devmem) transmit path
relies on the socket's route cache (`dst_entry`) to
validate that the packet is being sent via the network
device to which the DMA buffer was bound.

However, this check incorrectly fails and returns `-ENODEV`
if the socket's route cache entry (`dst`) is merely missing
or expired (`dst == NULL`). This scenario is observed during
network events, such as when flow steering rules are deleted,
leading to a temporary route cache invalidation.

This patch fixes -ENODEV error for `net_devmem_get_binding()`
by doing the following:

1.  It attempts to rebuild the route via `rebuild_header()`
if the route is initially missing (`dst == NULL`). This
allows the TCP/IP stack to recover from transient route
cache misses.
2.  It uses `rcu_read_lock()` and `dst_dev_rcu()` to safely
access the network device pointer (`dst_dev`) from the
route, preventing use-after-free conditions if the
device is concurrently removed.
3.  It maintains the critical safety check by validating
that the retrieved destination device (`dst_dev`) is
exactly the device registered in the Devmem binding
(`binding->dev`).

These changes prevent unnecessary ENODEV failures while
maintaining the critical safety requirement that the
Devmem resources are only used on the bound network device.

Queue maxSDU requirement of 802.1 Qbv standard requires mac to drop
packets that exceeds maxSDU length and maxSDU doesn't include
preamble, destination and source address, or FCS but includes
ethernet type and VLAN header.

On hardware with Tx VLAN offload enabled, VLAN header length is not
included in the skb->len, when Tx VLAN offload is requested. This
leads to incorrect length checks and allows transmission of
oversized packets. Add the VLAN_HLEN to the skb->len before checking
the Qbv maxSDU if Tx VLAN offload is requested for the packet.

when it is configured. This behavior is not documented and leads to
inconsistent double VLAN tagging.

Additionally, an unexpected CTAG with VLAN ID 0 is inserted, resulting
in frames like:

Frame 1: 110 bytes on wire (880 bits), 110 bytes captured (880 bits)
Ethernet II, Src: <src> (<src>), Dst: <dst> (<dst>)
IEEE 802.1ad, ID: 100
802.1Q Virtual LAN, PRI: 0, DEI: 0, ID: 0 (unexpected)
802.1Q Virtual LAN, PRI: 0, DEI: 0, ID: 200
Internet Protocol Version 4, Src: 192.168.4.10, Dst: 192.168.4.11
Internet Control Message Protocol

To avoid this undocumented and incorrect behavior, disable 802.1AD tag
insertion offload. Also, don't set CSVL bit. As per the data book,
when this bit is set, S-VLAN type (0x88A8) is inserted in the 13th and
14th bytes of transmitted packets and when this bit is reset, C-VLAN
type (0x8100) is inserted in the 13th and 14th bytes of transmitted
packets.

b5171b8996 Merge branch 'net-enetc-add-i-mx94-enetc-support'
Wei Fang says:

====================
net: enetc: Add i.MX94 ENETC support

i.MX94 NETC has two kinds of ENETCs, one is the same as i.MX95, which
can be used as a standalone network port. The other one is an internal
ENETC, it connects to the CPU port of NETC switch through the pseudo
MAC. Also, i.MX94 have multiple PTP Timers, which is different from
i.MX95. Any PTP Timer can be bound to a specified standalone ENETC by
the IERB ETBCR registers. Currently, this patch only add ENETC support
and Timer support for i.MX94. The switch will be added by a separate
patch set.

In addition, note that i.MX94 SoC is launched after i.MX95, its NETC
has a higher version, so the driver support is added after i.MX95.

2d673b0e2f net: enetc: add standalone ENETC support for i.MX94
The revision of i.MX94 ENETC is changed to v4.3, so add this revision to
enetc_info to support i.MX94 ENETC. And add PTP suspport for i.MX94.

5175c1e4ad net: enetc: add basic support for the ENETC with pseudo MAC for i.MX94
The ENETC with pseudo MAC is an internal port which connects to the CPU
port of the switch. The switch CPU/host ENETC is fully integrated with
the switch and does not require a back-to-back MAC, instead a light
weight "pseudo MAC" provides the delineation between switch and ENETC.
This translates to lower power (less logic and memory) and lower delay
(as there is no serialization delay across this link).

Different from the standalone ENETC which is used as the external port,
the internal ENETC has a different PCIe device ID, and it does not have
Ethernet MAC port registers, instead, it has a small number of pseudo
MAC port registers, so some features are not supported by pseudo MAC,
such as loopback, half duplex, one-step timestamping and so on.

Therefore, the configuration of this internal ENETC is also somewhat
different from that of the standalone ENETC. So add the basic support
for ENETC with pseudo MAC. More supports will be added in the future.

1cd3f21c18 net: enetc: add ptp timer binding support for i.MX94
The i.MX94 has three PTP timers, and all standalone ENETCs can select
one of them to bind to as their PHC. The 'ptp-timer' property is used
to represent the PTP device of the Ethernet controller. So users can
add 'ptp-timer' to the ENETC node to specify the PTP timer. The driver
parses this property to bind the two hardware devices.

If the "ptp-timer" property is not present, the first timer of the PCIe
bus where the ENETC is located is used as the default bound PTP timer.
