octeontx2-af: APR Mapping Fixes
This patch series includes fixes related to APR (LMT)
mapping and debugfs support.
Changes include:
Patch 1:Set LMT_ENA bit for APR table entries.
Enables the LMT line for each PF/VF by setting
the LMT_ENA bit in the APR_LMT_MAP_ENTRY_S
structure.
Patch-2:Fix APR entry in debugfs
The APR table was previously mapped using a fixed size,
which could lead to incorrect mappings when the number
of PFs and VFs differed from the assumed value.
This patch updates the logic to calculate the APR table
size dynamically, based on values from the APR_LMT_CFG
register, ensuring correct representation in debugfs.
====================
Link: https://patch.msgid.link/20250521060834.19780-1-gakula@marvell.com
Signed-off-by: Paolo Abeni <pabeni@redhat.com>
The current implementation maps the APR table using a fixed size,
which can lead to incorrect mapping when the number of PFs and VFs
varies.
This patch corrects the mapping by calculating the APR table
size dynamically based on the values configured in the
APR_LMT_CFG register, ensuring accurate representation
of APR entries in debugfs.

This patch enables the LMT line for a PF/VF by setting the
LMT_ENA bit in the APR_LMT_MAP_ENTRY_S structure.
Additionally, it simplifies the logic for calculating the
LMTST table index by consistently using the maximum
number of hw supported VFs (i.e., 256).

After freed the tipc_crypto tx by delete namespace, tipc_aead_encrypt_done

I reproduce this issue by:
ip netns add ns1

ip link set veth1 netns ns1
ip netns exec ns1 tipc bearer enable media eth dev veth1
ip netns exec ns1 tipc node set key this_is_a_master_key master
ip netns exec ns1 tipc bearer disable media eth dev veth1
ip netns del ns1
The key of reproduction is that, simd_aead_encrypt is interrupted, leading
to crypto_simd_usable() return false. Thus, the cryptd_queue_worker is
triggered, and the tipc_crypto tx will be visited.
tipc_disc_timeout
tipc_bearer_xmit_skb
tipc_crypto_xmit
tipc_aead_encrypt
crypto_aead_encrypt
// encrypt()
simd_aead_encrypt
// crypto_simd_usable() is false
child = &ctx->cryptd_tfm->base;
simd_aead_encrypt
crypto_aead_encrypt
// encrypt()
cryptd_aead_encrypt_enqueue
cryptd_aead_enqueue
cryptd_enqueue_request
// trigger cryptd_queue_worker
queue_work_on(smp_processor_id(), cryptd_wq, &cpu_queue->work)
Fix this by holding net reference count before encrypt.

net_sched: Fix HFSC qlen/backlog accounting bug and add selftest
This series addresses a long-standing bug in the HFSC qdisc where queue length
and backlog accounting could become inconsistent if a packet is dropped during
a peek-induced dequeue operation, and adds a corresponding selftest to tc-testing.

This test reproduces a scenario where HFSC queue length and backlog accounting
can become inconsistent when a peek operation triggers a dequeue and possible
drop before the parent qdisc updates its counters. The test sets up a DRR root
qdisc with an HFSC class, netem, and blackhole children, and uses Scapy to
inject a packet. It helps to verify that HFSC correctly tracks qlen and backlog
even when packets are dropped during peek-induced dequeue.

When enqueuing the first packet to an HFSC class, hfsc_enqueue() calls the
child qdisc's peek() operation before incrementing sch->q.qlen and
sch->qstats.backlog. If the child qdisc uses qdisc_peek_dequeued(), this may
trigger an immediate dequeue and potential packet drop. In such cases,
qdisc_tree_reduce_backlog() is called, but the HFSC qdisc's qlen and backlog
have not yet been updated, leading to inconsistent queue accounting. This
can leave an empty HFSC class in the active list, causing further
consequences like use-after-free.
This patch fixes the bug by moving the increment of sch->q.qlen and
sch->qstats.backlog before the call to the child qdisc's peek() operation.
This ensures that queue length and backlog are always accurate when packet
drops or dequeues are triggered during the peek.

If a shorter than assumed transfer was seen, a partial buffer will have
been filled. For that case it isn't sane to attempt to fill more into
the bundle before posting a completion, as that will cause a gap in
the received data.
Check if the iterator has hit zero and only allow to continue a bundle
operation if that is the case.
Also ensure that for putting finished buffers, only the current transfer
is accounted. Otherwise too many buffers may be put for a short transfer.

If the driver reset fails, it may not work properly.
Therefore, the ndo.open() operation should be rejected.
In this patch, the driver calls netif_device_detach()
before the reset and calls netif_device_attach()
after the reset succeeds. If the reset fails,
netif_device_attach() is not called. Therefore,
netdev does not present and cannot be opened.
If reset fails, only the PCI reset (via sysfs)
can be used to attempt recovery.

Commit 4dbd2b2ebe ("nvme-multipath: Add visibility for round-robin
io-policy") introduced the creation of the multipath sysfs group under
the NVMe head gendisk device node. However, it also inadvertently added
the same sysfs group under each namespace path device which head node
refers to and that is incorrect.
The multipath sysfs group should only be exposed through the namespace
head gendisk node. This is sufficient, as the head device already
provides symbolic links to the individual namespace paths it manages.
This patch fixes the issue by preventing the creation of the multipath
sysfs group under namespace path devices, ensuring it only appears under
the head disk node.

Commit 5ef44b3cb4 ("xsk: Bring back busy polling support") fixed the
busy polling support in xsk for XDP_ZEROCOPY after it was broken in
commit 86e25f40aa ("net: napi: Add napi_config"). The busy polling
support with XDP_COPY remained broken since the napi_id setup in
xsk_rcv_check was removed.
Bring back the setup of napi_id for XDP_COPY so socket level SO_BUSYPOLL
can be used to poll the underlying napi.
Do the setup of napi_id for XDP_COPY in xsk_bind, as it is done
currently for XDP_ZEROCOPY. The setup of napi_id for XDP_COPY in
xsk_bind is safe because xsk_rcv_check checks that the rx queue at which
the packet arrives is equal to the queue_id that was supplied in bind.
This is done for both XDP_COPY and XDP_ZEROCOPY mode.
Tested using AF_XDP support in virtio-net by running the xsk_rr AF_XDP
benchmarking tool shared here:

was already held. rcu_dereference_protected() is the correct
conversion after replacing rtnl_lock with netdev_lock.
Add a new helper netdev_lock_dereference() similar to
rtnl_dereference().

While the MDIO address of the internal PHY on Allwinner sun8i chips is
generally 1, of_mdio_parse_addr is used to cleanly parse the address
from the device-tree instead of hardcoding it.
A commit reworking the code ditched the parsed value and hardcoded the
value 1 instead, which didn't really break anything but is more fragile
and not future-proof.
Restore the initial behavior using the parsed address returned from the
helper.

On Qualcomm platforms if the board uses GPIO hogs msm_pinmux_request()
calls gpiochip_line_is_valid(). After commit 8015443e24 ("gpio: Hide
valid_mask from direct assignments") gpiochip_line_is_valid() uses
gc->gpiodev, which is NULL when GPIO hog pins are being processed.
Thus after this commit using GPIO hogs causes the following crash. In
order to fix this, verify that gc->gpiodev is not NULL.
Note: it is not possible to reorder calls (e.g. by calling
msm_gpio_init() before pinctrl registration or by splitting
pinctrl_register() into _and_init() and pinctrl_enable() and calling the
latter function after msm_gpio_init()) because GPIO chip registration
would fail with EPROBE_DEFER if pinctrl is not enabled at the time of
registration.

are identical (if redundant) for CONFIG_IO_URING=y. But if
CONFIG_IO_URING=N, include/linux/io_uring/cmd.h declares the function as
static inline while io_uring/uring_cmd.h declares it as extern. This

Going bus-off on a channel doing RX could result in dropped packets.
As netif_running() gets cleared before the channel abort procedure,
the handling of any last RDATA packets would see netif_rx() return
non-zero to signal a dropped packet. kvaser_pciefd_read_buffer() dealt
with this "error" by breaking out of processing the remaining DMA RX
buffer.
Only return an error from kvaser_pciefd_read_buffer() due to packet
corruption, otherwise handle it internally.

The functions kvaser_pciefd_start_xmit() and
kvaser_pciefd_handle_ack_packet() raced to stop/wake TX queues and
get/put echo skbs, as kvaser_pciefd_can->echo_lock was only ever taken
when transmitting and KCAN_TX_NR_PACKETS_CURRENT gets decremented
prior to handling of ACKs. E.g., this caused the following error:
can_put_echo_skb: BUG! echo_skb 5 is occupied!
Instead, use the synchronization helpers in netdev_queues.h. As those
piggyback on BQL barriers, start updating in-flight packets and bytes
counts as well.

and it has been in linux-next for several days, but if I wait until
the merge window to ask for it to be pulled, orangefs will be broken
in 6.15 too.
I hope you can pull this patch during 6.15-rc7.
