fbnic takes 4 parameters to configure the Rx queues. The semantics
are similar to other existing NICs but confusing to newcomers.
Document it.

If no PHY device is found (e.g., for LAN7801 in fixed-link mode),
lan78xx_phy_init() may proceed to dereference a NULL phydev pointer,
leading to a crash.
Update the logic to perform MAC configuration first, then check for the presence
of a PHY. For the fixed-link case, set up the fixed link and return early,
bypassing any code that assumes a valid phydev pointer.
It is safe to move lan78xx_mac_prepare_for_phy() earlier because this function
only uses information from dev->interface, which is configured by
lan78xx_get_phy() beforehand. The function does not access phydev or any data
set up by later steps.

At the time of commit bc51dddf98c9 ("netns: avoid disabling irq
for netns id") peernet2id() was not yet using RCU.
Commit 2dce224f469f ("netns: protect netns
ID lookups with RCU") changed peernet2id() to no longer
acquire net->nsid_lock (potentially from BH context).
We do not need to block soft interrupts when acquiring
net->nsid_lock anymore.

Remove redundant netif_napi_del() call from disconnect path.
A WARN may be triggered in __netif_napi_del_locked() during USB device
disconnect:
WARNING: CPU: 0 PID: 11 at net/core/dev.c:7417 __netif_napi_del_locked+0x2b4/0x350
This happens because netif_napi_del() is called in the disconnect path while
NAPI is still enabled. However, it is not necessary to call netif_napi_del()
explicitly, since unregister_netdev() will handle NAPI teardown automatically
and safely. Removing the redundant call avoids triggering the warning.

Some counters in enetc_port_counters are 32-bit registers, and some are
64-bit registers. But in the current driver, they are all read through
enetc_port_rd(), which can only read a 32-bit value. Therefore, separate
64-bit counters (enetc_pm_counters) from enetc_port_counters and use
enetc_port_rd64() to read the 64-bit statistics.

The statistics of the ring are all unsigned int type, so the statistics
will overflow quickly under heavy traffic. In addition, the statistics
of struct net_device_stats are obtained from struct enetc_ring_stats,
but the statistics of net_device_stats are unsigned long type. So it is
better to keep the statistics types consistent in these two structures.
Considering these two factors, and the fact that both LS1028A and i.MX95
are arm64 architecture, the statistics of enetc_ring_stats are changed
to unsigned long type. Note that unsigned int and unsigned long are the
same thing on some systems, and on such systems there is no overflow
advantage of one over the other.

In the current implementation, IP coalescing is always enabled and
cannot be disabled.
As setting maximum frames to 0 or 1, or setting delay to zero implies
immediate delivery of single packets/IRQs, disable coalescing in
hardware in these cases.
This also guarantees that coalescing is never enabled with ICFT or ICTT
set to zero, a configuration that could lead to unpredictable behaviour
according to i.MX8MP reference manual.

tl;dr
=====
Add a new neighbor flag ("extern_valid") that can be used to indicate to
the kernel that a neighbor entry was learned and determined to be valid
externally. The kernel will not try to remove or invalidate such an
entry, leaving these decisions to the user space control plane. This is
needed for EVPN multi-homing where a neighbor entry for a multi-homed
host needs to be synced across all the VTEPs among which the host is
multi-homed.
Background
==========
In a typical EVPN multi-homing setup each host is multi-homed using a
set of links called ES (Ethernet Segment, i.e., LAG) to multiple leaf
switches (VTEPs). VTEPs that are connected to the same ES are called ES
peers.
When a neighbor entry is learned on a VTEP, it is distributed to both ES
peers and remote VTEPs using EVPN MAC/IP advertisement routes. ES peers
use the neighbor entry when routing traffic towards the multi-homed host
and remote VTEPs use it for ARP/NS suppression.
Motivation
==========
If the ES link between a host and the VTEP on which the neighbor entry
was locally learned goes down, the EVPN MAC/IP advertisement route will
be withdrawn and the neighbor entries will be removed from both ES peers
and remote VTEPs. Routing towards the multi-homed host and ARP/NS
suppression can fail until another ES peer locally learns the neighbor
entry and distributes it via an EVPN MAC/IP advertisement route.
"draft-rbickhart-evpn-ip-mac-proxy-adv-03" [1] suggests avoiding these
intermittent failures by having the ES peers install the neighbor
entries as before, but also injecting EVPN MAC/IP advertisement routes
with a proxy indication. When the previously mentioned ES link goes down
and the original EVPN MAC/IP advertisement route is withdrawn, the ES
peers will not withdraw their neighbor entries, but instead start aging
timers for the proxy indication.
If an ES peer locally learns the neighbor entry (i.e., it becomes
"reachable"), it will restart its aging timer for the entry and emit an
EVPN MAC/IP advertisement route without a proxy indication. An ES peer
will stop its aging timer for the proxy indication if it observes the
removal of the proxy indication from at least one of the ES peers
advertising the entry.
In the event that the aging timer for the proxy indication expired, an
ES peer will withdraw its EVPN MAC/IP advertisement route. If the timer
expired on all ES peers and they all withdrew their proxy
advertisements, the neighbor entry will be completely removed from the
EVPN fabric.
Implementation
==============
In the above scheme, when the control plane (e.g., FRR) advertises a
neighbor entry with a proxy indication, it expects the corresponding
entry in the data plane (i.e., the kernel) to remain valid and not be
removed due to garbage collection or loss of carrier. The control plane
also expects the kernel to notify it if the entry was learned locally
(i.e., became "reachable") so that it will remove the proxy indication
from the EVPN MAC/IP advertisement route. That is why these entries
cannot be programmed with dummy states such as "permanent" or "noarp".
Instead, add a new neighbor flag ("extern_valid") which indicates that
the entry was learned and determined to be valid externally and should
not be removed or invalidated by the kernel. The kernel can probe the
entry and notify user space when it becomes "reachable" (it is initially
installed as "stale"). However, if the kernel does not receive a
confirmation, have it return the entry to the "stale" state instead of
the "failed" state.
In other words, an entry marked with the "extern_valid" flag behaves
like any other dynamically learned entry other than the fact that the
kernel cannot remove or invalidate it.
One can argue that the "extern_valid" flag should not prevent garbage
collection and that instead a neighbor entry should be programmed with
both the "extern_valid" and "extern_learn" flags. There are two reasons
for not doing that:
1. Unclear why a control plane would like to program an entry that the
kernel cannot invalidate but can completely remove.
2. The "extern_learn" flag is used by FRR for neighbor entries learned
on remote VTEPs (for ARP/NS suppression) whereas here we are
concerned with local entries. This distinction is currently irrelevant
for the kernel, but might be relevant in the future.
Given that the flag only makes sense when the neighbor has a valid
state, reject attempts to add a neighbor with an invalid state and with
this flag set. For example:
# ip neigh add 192.0.2.1 nud none dev br0.10 extern_valid
Error: Cannot create externally validated neighbor with an invalid state.
# ip neigh add 192.0.2.1 lladdr 00:11:22:33:44:55 nud stale dev br0.10 extern_valid
# ip neigh replace 192.0.2.1 nud failed dev br0.10 extern_valid
Error: Cannot mark neighbor as externally validated with an invalid state.
The above means that a neighbor cannot be created with the
"extern_valid" flag and flags such as "use" or "managed" as they result
in a neighbor being created with an invalid state ("none") and
immediately getting probed:
# ip neigh add 192.0.2.1 lladdr 00:11:22:33:44:55 nud stale dev br0.10 extern_valid use
Error: Cannot create externally validated neighbor with an invalid state.
However, these flags can be used together with "extern_valid" after the
neighbor was created with a valid state:
# ip neigh add 192.0.2.1 lladdr 00:11:22:33:44:55 nud stale dev br0.10 extern_valid
# ip neigh replace 192.0.2.1 lladdr 00:11:22:33:44:55 nud stale dev br0.10 extern_valid use
One consequence of preventing the kernel from invalidating a neighbor
entry is that by default it will only try to determine reachability
using unicast probes. This can be changed using the "mcast_resolicit"
sysctl:
# sysctl net.ipv4.neigh.br0/10.mcast_resolicit
0
# tcpdump -nn -e -i br0.10 -Q out arp &
# ip neigh replace 192.0.2.1 lladdr 00:11:22:33:44:55 nud stale dev br0.10 extern_valid use

"Now that anonymous inodes set S_IFREG, this breaks the io_uring
read/write retries for short reads/writes. As things like timerfd and
eventfd are anon inodes, applications that previously did:
unsigned long event_data[2];
io_uring_prep_read(sqe, evfd, event_data, sizeof(event_data), 0);
and just got a short read when 1 event was posted, will now wait for
the full amount before posting a completion.
This caused issues for the ghostty application, making it basically
unusable due to excessive buffering"

====================
net: ethtool: consistently take rss_lock for all rxfh ops
I'd like to bring RXFH and RXFHINDIR ioctls under a single set of
Netlink ops. It appears that while core takes the ethtool->rss_lock
around some of the RXFHINDIR ops, drivers (sfc) take it internally
for the RXFH.
Consistently take the lock around all ops and accesses to the XArray
within the core. This should hopefully make the rss_lock a lot less
confusing.

We already call get_rxfh under the rss_lock when we read back
context state after changes. Let's be consistent and always
hold the lock. The existing callers are all under rtnl_lock
so this should make no difference in practice, but it makes
the locking rules far less confusing IMHO. Any RSS callback
and any access to the RSS XArray should hold the lock.

Netlink code will want to perform the RSS_SET operation atomically
under the rss_lock. sfc wants to hold the rss_lock in rxfh_fields_get,
which makes that difficult. Lets move the locking up to the core
so that for all driver-facing callbacks rss_lock is taken consistently
by the core.

Always take the rss_lock in ethtool_set_rxfh(). We will want to
make a similar change in ethtool_set_rxfh_fields() and some
drivers lock that callback regardless of rss context ID being set.
Having some callbacks locked unconditionally and some only if
context ID is set would be very confusing.
ethtool handling is under rtnl_lock, so rss_lock is very unlikely
to ever be congested.

io_uring marks a request as dealing with a regular file on S_ISREG. This
drives things like retries on short reads or writes, which is generally
not expected on a regular file (or bdev). Applications tend to not
expect that, so io_uring tries hard to ensure it doesn't deliver short
IO on regular files.
However, a recent commit added S_IFREG to anonymous inodes. When
io_uring is used to read from various things that are backed by anon
inodes, like eventfd, timerfd, etc, then it'll now all of a sudden wait
for more data when rather than deliver what was read or written in a
single operation. This breaks applications that issue reads on anon
inodes, if they ask for more data than a single read delivers.
Add a check for !S_ANON_INODE as well before setting REQ_F_ISREG to
prevent that.

Pull tracing fix from Steven Rostedt:
- Fix possible UAF on error path in filter_free_subsystem_filters()
When freeing a subsystem filter, the filter for the subsystem is
passed in to be freed and all the events within the subsystem will
have their filter freed too. In order to free without waiting for RCU
synchronization, list items are allocated to hold what is going to be
freed to free it via a call_rcu(). If the allocation of these items
fails, it will call the synchronization directly and free after that
(causing a bit of delay for the user).
The subsystem filter is first added to this list and then the filters
for all the events under the subsystem. The bug is if one of the
allocations of the list items for the event filters fail to allocate,
it jumps to the "free_now" label which will free the subsystem
filter, then all the items on the allocated list, and then the event
filters that were not added to the list yet. But because the
subsystem filter was added first, it gets freed twice.
The solution is to add the subsystem filter after the events, and
then if any of the allocations fail it will not try to free any of
them twice

According to Documentation/PCI/pci-error-recovery.rst only the
error_detected() callback in the err_handler struct is mandatory for
a driver to support error recovery. So far s390's error recovery chose
a stricter approach also requiring slot_reset() and resume().
Relax this requirement and only require error_detected(). If a callback
is not implemented EEH and AER treat this as PCI_ERS_RESULT_NONE. This
return value is otherwise used by drivers abstaining from their vote
on how to proceed with recovery and currently also not supported by
s390's recovery code.
So to support missing callbacks in-line with other implementors of the
recovery flow, also handle PCI_ERS_RESULT_NONE. Since s390 only does per
PCI function recovery and does not do voting, treat PCI_ERS_RESULT_NONE
optimistically and proceed through recovery unless other failures
prevent this.

The error event information for PCI error events contains a function
handle for the respective function. This handle is generally captured at
the time the error event was recorded. Due to delays in processing or
cascading issues, it may happen that during firmware recovery multiple
events are generated. When processing these events in order Linux may
already have recovered an affected function making the event information
stale. Fix this by doing an unconditional CLP List PCI function
retrieving the current function handle with the zdev->state_lock held
and ignoring the event if its function handle is stale.

This manifests as a NULL pointer reference on some compilers, but
could trigger in other ways
- Misaligned accesses from userspace at faulting addresses are now
handled correctly
- A fix for an incorrect optimization that allowed access_ok() to mark
invalid addresses as accessible, which can result in userspace
triggering BUG()s
- A few fixes for build warnings, and an update to Drew's email address
