net: dummy: request ops lock
Even though dummy device doesn't really need an instance lock, a lot of selftests use dummy so it's useful to have extra expose to the instance lock on NIPA. Request the instance/ops locking.

netdevsim: add dummy device notifiers
In order to exercise and verify notifiers' locking assumptions, register dummy notifiers (via register_netdevice_notifier_dev_net). Share notifier event handler that enforces the assumptions with lock_debug.c (rename and export rtnl_net_debug_event as netdev_debug_event). Add ops lock asserts to netdev_debug_event.

net: use netif_disable_lro in ipv6_add_dev
ipv6_add_dev might call dev_disable_lro which unconditionally grabs
instance lock, so it will deadlock during NETDEV_REGISTER. Switch

net: airoha: Validate egress gdm port in airoha_ppe_foe_entry_prepare()
Dev pointer in airoha_ppe_foe_entry_prepare routine is not strictly
a device allocated by airoha_eth driver since it is an egress device
and the flowtable can contain even wlan, pppoe or vlan devices. E.g:
flowtable ft {
hook ingress priority filter
devices = { eth1, lan1, lan2, lan3, lan4, wlan0 }
flags offload ^
|
"not allocated by airoha_eth" --
}
In this case airoha_get_dsa_port() will just return the original device
pointer and we can't assume netdev priv pointer points to an
airoha_gdm_port struct.
Fix the issue validating egress gdm port in airoha_ppe_foe_entry_prepare
routine before accessing net_device priv pointer.

net: dsa: mv88e6xxx: propperly shutdown PPU re-enable timer on destroy
The mv88e6xxx has an internal PPU that polls PHY state. If we want to
access the internal PHYs, we need to disable the PPU first. Because
that is a slow operation, a 10ms timer is used to re-enable it,
canceled with every access, so bulk operations effectively only
disable it once and re-enable it some 10ms after the last access.
If a PHY is accessed and then the mv88e6xxx module is removed before
the 10ms are up, the PPU re-enable ends up accessing a dangling pointer.
This especially affects probing during bootup. The MDIO bus and PHY
registration may succeed, but registration with the DSA framework
may fail later on (e.g. because the CPU port depends on another,
very slow device that isn't done probing yet, returning -EPROBE_DEFER).
In this case, probe() fails, but the MDIO subsystem may already have
accessed the MIDO bus or PHYs, arming the timer.
This is fixed as follows:
- If probe fails after mv88e6xxx_phy_init(), make sure we also call
mv88e6xxx_phy_destroy() before returning
- In mv88e6xxx_remove(), make sure we do the teardown in the correct
order, calling mv88e6xxx_phy_destroy() after unregistering the
switch device.
- In mv88e6xxx_phy_destroy(), destroy both the timer and the work item
that the timer might schedule, synchronously waiting in case one of
the callbacks already fired and destroying the timer first, before
waiting for the work item.
- Access to the PPU is guarded by a mutex, the worker acquires it
with a mutex_trylock(), not proceeding with the expensive shutdown
if that fails. We grab the mutex in mv88e6xxx_phy_destroy() to make
sure the slow PPU shutdown is already done or won't even enter, when
we wait for the work item.

ipv6: fix omitted netlink attributes when using RTEXT_FILTER_SKIP_STATS
Using RTEXT_FILTER_SKIP_STATS is incorrectly skipping non-stats IPv6
netlink attributes on link dump. This causes issues on userspace tools,
e.g iproute2 is not rendering address generation mode as it should due
to missing netlink attribute.
Move the filling of IFLA_INET6_STATS and IFLA_INET6_ICMP6STATS to a
helper function guarded by a flag check to avoid hitting the same
situation in the future.

eth: bnxt: fix deadlock in the mgmt_ops
When queue is being reset, callbacks of mgmt_ops are called by
netdev_nl_bind_rx_doit().
The netdev_nl_bind_rx_doit() first acquires netdev_lock() and then calls
callbacks.
So, mgmt_ops callbacks should not acquire netdev_lock() internaly.
The bnxt_queue_{start | stop}() calls napi_{enable | disable}() but they
internally acquire netdev_lock().
So, deadlock occurs.
To avoid deadlock, napi_{enable | disable}_locked() should be used
instead.

Looking at the kernel code, I see that kernel does add link-local address automatically in init_loopback(), but that is called from ipv6 notifier block. So, in turn the userspace that brought up the loopback interface may see rtnetlink ACK earlier than addrconf_notify() does it's job (at least, on a slow VM such as netdev). Probably, for ipv4 it's the same, judging by inetdev_event(). The fix is quite simple: set the link-local route straight after bringing the loopback interface. That will make it synchronous.

vsock: avoid timeout during connect() if the socket is closing
When a peer attempts to establish a connection, vsock_connect() contains
a loop that waits for the state to be TCP_ESTABLISHED. However, the
other peer can be fast enough to accept the connection and close it
immediately, thus moving the state to TCP_CLOSING.
When this happens, the peer in the vsock_connect() is properly woken up,
but since the state is not TCP_ESTABLISHED, it goes back to sleep
until the timeout expires, returning -ETIMEDOUT.
If the socket state is TCP_CLOSING, waiting for the timeout is pointless.
vsock_connect() can return immediately without errors or delay since the
connection actually happened. The socket will be in a closing state,
but this is not an issue, and subsequent calls will fail as expected.
We discovered this issue while developing a test that accepts and
immediately closes connections to stress the transport switch between
two connect() calls, where the first one was interrupted by a signal
(see Closes link).

Merge branch 'udp-fix-two-integer-overflows-when-sk-sk_rcvbuf-is-close-to-int_max'
Kuniyuki Iwashima says: ==================== udp: Fix two integer overflows when sk->sk_rcvbuf is close to INT_MAX. I got a report that UDP mem usage in /proc/net/sockstat did not drop even after an application was terminated. The issue could happen if sk->sk_rmem_alloc wraps around due to a large sk->sk_rcvbuf, which was INT_MAX in our case.

udp: Fix memory accounting leak.
Matt Dowling reported a weird UDP memory usage issue.
Under normal operation, the UDP memory usage reported in /proc/net/sockstat
remains close to zero. However, it occasionally spiked to 524,288 pages
and never dropped. Moreover, the value doubled when the application was
terminated. Finally, it caused intermittent packet drops.
We can reproduce the issue with the script below [0]:
1. /proc/net/sockstat reports 0 pages
# cat /proc/net/sockstat | grep UDP:
UDP: inuse 1 mem 0
2. Run the script till the report reaches 524,288
# python3 test.py & sleep 5
# cat /proc/net/sockstat | grep UDP:
UDP: inuse 3 mem 524288 <-- (INT_MAX + 1) >> PAGE_SHIFT
3. Kill the socket and confirm the number never drops
# pkill python3 && sleep 5
# cat /proc/net/sockstat | grep UDP:
UDP: inuse 1 mem 524288
4. (necessary since v6.0) Trigger proto_memory_pcpu_drain()
# python3 test.py & sleep 1 && pkill python3
5. The number doubles
# cat /proc/net/sockstat | grep UDP:
UDP: inuse 1 mem 1048577
The application set INT_MAX to SO_RCVBUF, which triggered an integer
overflow in udp_rmem_release().
When a socket is close()d, udp_destruct_common() purges its receive
queue and sums up skb->truesize in the queue. This total is calculated
and stored in a local unsigned integer variable.
The total size is then passed to udp_rmem_release() to adjust memory
accounting. However, because the function takes a signed integer
argument, the total size can wrap around, causing an overflow.
Then, the released amount is calculated as follows:
1) Add size to sk->sk_forward_alloc.
2) Round down sk->sk_forward_alloc to the nearest lower multiple of
PAGE_SIZE and assign it to amount.
3) Subtract amount from sk->sk_forward_alloc.
4) Pass amount >> PAGE_SHIFT to __sk_mem_reduce_allocated().
When the issue occurred, the total in udp_destruct_common() was 2147484480
(INT_MAX + 833), which was cast to -2147482816 in udp_rmem_release().
At 1) sk->sk_forward_alloc is changed from 3264 to -2147479552, and
2) sets -2147479552 to amount. 3) reverts the wraparound, so we don't
see a warning in inet_sock_destruct(). However, udp_memory_allocated
ends up doubling at 4).

udp: Fix multiple wraparounds of sk->sk_rmem_alloc.
__udp_enqueue_schedule_skb() has the following condition:
if (atomic_read(&sk->sk_rmem_alloc) > sk->sk_rcvbuf)
goto drop;
sk->sk_rcvbuf is initialised by net.core.rmem_default and later can
be configured by SO_RCVBUF, which is limited by net.core.rmem_max,
or SO_RCVBUFFORCE.
If we set INT_MAX to sk->sk_rcvbuf, the condition is always false
as sk->sk_rmem_alloc is also signed int.
Then, the size of the incoming skb is added to sk->sk_rmem_alloc
unconditionally.
This results in integer overflow (possibly multiple times) on
sk->sk_rmem_alloc and allows a single socket to have skb up to
net.core.udp_mem[1].
For example, if we set a large value to udp_mem[1] and INT_MAX to
sk->sk_rcvbuf and flood packets to the socket, we can see multiple
overflows:
# cat /proc/net/sockstat | grep UDP:
UDP: inuse 3 mem 7956736 <-- (7956736 << 12) bytes > INT_MAX * 15
^- PAGE_SHIFT
# ss -uam
State Recv-Q ...
UNCONN -1757018048 ... <-- flipping the sign repeatedly
skmem:(r2537949248,rb2147483646,t0,tb212992,f1984,w0,o0,bl0,d0)
Previously, we had a boundary check for INT_MAX, which was removed by

rtnetlink: Use register_pernet_subsys() in rtnl_net_debug_init().
rtnl_net_debug_init() registers rtnl_net_debug_net_ops by
register_pernet_device() but calls unregister_pernet_subsys()
in case register_netdevice_notifier() fails.
It corrupts pernet_list because first_device is updated in
register_pernet_device() but not unregister_pernet_subsys().
Let's fix it by calling register_pernet_subsys() instead.
The _subsys() one fits better for the use case because it keeps
the notifier alive until default_device_exit_net(), giving it
more chance to test NETDEV_UNREGISTER.

net: mvpp2: Prevent parser TCAM memory corruption
Protect the parser TCAM/SRAM memory, and the cached (shadow) SRAM
information, from concurrent modifications.
Both the TCAM and SRAM tables are indirectly accessed by configuring
an index register that selects the row to read or write to. This means
that operations must be atomic in order to, e.g., avoid spreading
writes across multiple rows. Since the shadow SRAM array is used to
find free rows in the hardware table, it must also be protected in
order to avoid TOCTOU errors where multiple cores allocate the same
row.
This issue was detected in a situation where `mvpp2_set_rx_mode()` ran
concurrently on two CPUs. In this particular case the
MVPP2_PE_MAC_UC_PROMISCUOUS entry was corrupted, causing the
classifier unit to drop all incoming unicast - indicated by the
`rx_classifier_drops` counter.

selftests: tc-testing: Add TBF with SKBPRIO queue length corner case test
Add a test case to validate the interaction between TBF and SKBPRIO queueing disciplines, specifically targeting queue length accounting corner cases. This test complements the fix for the queue length accounting issue in the SKBPRIO qdisc. This is still best-effort, as timing and manipulating enqueue and dequeue from user-space is very hard.

net_sched: skbprio: Remove overly strict queue assertions
In the current implementation, skbprio enqueue/dequeue contains an assertion
that fails under certain conditions when SKBPRIO is used as a child qdisc under
TBF with specific parameters. The failure occurs because TBF sometimes peeks at
packets in the child qdisc without actually dequeuing them when tokens are
unavailable.
This peek operation creates a discrepancy between the parent and child qdisc
queue length counters. When TBF later receives a high-priority packet,
SKBPRIO's queue length may show a different value than what's reflected in its
internal priority queue tracking, triggering the assertion.
The fix removes this overly strict assertions in SKBPRIO, they are not
necessary at all.

netlabel: Fix NULL pointer exception caused by CALIPSO on IPv4 sockets
When calling netlbl_conn_setattr(), addr->sa_family is used
to determine the function behavior. If sk is an IPv4 socket,
but the connect function is called with an IPv6 address,
the function calipso_sock_setattr() is triggered.
Inside this function, the following code is executed:
sk_fullsock(__sk) ? inet_sk(__sk)->pinet6 : NULL;
Since sk is an IPv4 socket, pinet6 is NULL, leading to a
null pointer dereference.
This patch fixes the issue by checking if inet6_sk(sk)
returns a NULL pointer before accessing pinet6.

- Relax IGD support code to match display class device rather than
specifically requiring a VGA device. (Tomita Moeko)
- Accelerate DMA mapping of device MMIO by iterating at PMD and PUD
levels to take advantage of huge pfnmap support added in v6.12.
(Alex Williamson)
- Extend virtio vfio-pci variant driver to include migration support
for block devices where enabled by the PF. (Yishai Hadas)
- Virtualize INTx PIN register for devices where the platform does
not route legacy PCI interrupts for the device and the interrupt
is reported as IRQ_NOTCONNECTED. (Alex Williamson)

iommufd 6.15 merge window pull
Two significant new items:
- Allow reporting IOMMU HW events to userspace when the events are clearly
linked to a device. This is linked to the VIOMMU object and is intended to
be used by a VMM to forward HW events to the virtual machine as part of
emulating a vIOMMU. ARM SMMUv3 is the first driver to use this
mechanism. Like the existing fault events the data is delivered through
a simple FD returning event records on read().
- PASID support in VFIO. "Process Address Space ID" is a PCI feature that
allows the device to tag all PCI DMA operations with an ID. The IOMMU
will then use the ID to select a unique translation for those DMAs. This
is part of Intel's vIOMMU support as VT-D HW requires the hypervisor to
manage each PASID entry. The support is generic so any VFIO user could
attach any translation to a PASID, and the support should work on ARM
SMMUv3 as well. AMD requires additional driver work.
Some minor updates, along with fixes:
- Prevent using nested parents with fault's, no driver support today
- Put a single "cookie_type" value in the iommu_domain to indicate what
owns the various opaque owner fields

More thermal control updates for 6.15-rc1
- Use dev_err_probe() helpers to simplify the init code in the Qoriq
thermal driver (Frank Li).
- Power down the Qoriq's TMU at suspend time (Alice Guo).
- Add ipq5332, ipq5424 compatible to the QCom's tsens thermal driver
and TSENS enable / calibration support for V2 (Praveenkumar I).
- Add missing rk3328 mapping entry (Trevor Woerner).
- Remove duplicate struct declaration from the thermal core header
file (Xueqin Luo).
- Disable the monitoring mode during suspend in the LVTS Mediatek
driver to prevent temperature acquisition glitches (Nícolas F. R. A.
Prado).
- Disable Stage 3 thermal threshold in the LVTS Mediatek driver
because it disables the suspend ability and does not have an
interrupt handler (Nícolas F. R. A. Prado).
- Fix low temperature offset interrupt in the LVTS Mediatek driver
to prevent multiple interrupts from triggering when the system is at
its normal functionning temperature (Nícolas F. R. A. Prado).
- Enable interrupts in the LVTS Mediatek driver only on sensors that
are in use (Nícolas F. R. A. Prado).
- Add the BCM74110 compatible DT binding and the corresponding code
to support a chip based on a different process node than previous
chips (Florian Fainelli).
- Correct indentation and style in DTS example (Krzysztof Kozlowski).
- Unify hexadecimal annotatation in the rcar_gen3 driver (Niklas
Söderlund).
- Factor out the code logic to read fuses on Gen3 and Gen4 in the
rcar_gen3 thermal driver (Niklas Söderlund).
- Drop unused driver data from the QCom's spmi temperature alarm
driver (Johan Hovold).

Char/Misc/IIO driver updates for 6.15-rc1
Here is the big set of char, misc, iio, and other smaller driver
subsystems for 6.15-rc1. Lots of stuff in here, including:
- loads of IIO changes and driver updates
- counter driver updates
- w1 driver updates
- faux conversions for some drivers that were abusing the platform bus
interface
- coresight driver updates
- rust miscdevice binding updates based on real-world-use
- other minor driver updates
All of these have been in linux-next with no reported issues for quite a
while.

Driver core updates for 6.15-rc1
Here is the big set of driver core updates for 6.15-rc1. Lots of stuff
happened this development cycle, including:
- kernfs scaling changes to make it even faster thanks to rcu
- bin_attribute constify work in many subsystems
- faux bus minor tweaks for the rust bindings
- rust binding updates for driver core, pci, and platform busses,
making more functionaliy available to rust drivers. These are all
due to people actually trying to use the bindings that were in 6.14.
- make Rafael and Danilo full co-maintainers of the driver core
codebase
- other minor fixes and updates.
This has been in linux-next for a while now, with the only reported
issue being some merge conflicts with the rust tree. Depending on which
tree you pull first, you will have conflicts in one of them. The merge
resolution has been in linux-next as an example of what to do, or can be
found here:
