Permit for PCS driver to define specific operation to tear down the link
between the MAC and the PCS.
This might be needed for some PCS that reset counter or require special
reset to correctly work if the link needs to be restored later.
On phylink_link_down() call, the additional phylink_pcs_link_down() will
be called after .mac_link_down to tear down the link.
PCS driver will need to define .pcs_link_down to make use of this.

* [RFC PATCH net-next v8 12/12] net: airoha: add phylink support
From: Christian Marangi @ 2026-06-18 12:57 UTC (permalink / raw)

In-Reply-To: <20260618125752.1223-1-ansuelsmth@gmail.com>
Add phylink support for each GDM port. For GDM1 add the internal interface
mode as the only supported mode. For GDM2/3/4 add the required
configuration of the PCS to make the external PHY or attached SFP cage
work.
These needs to be defined in the GDM port node using the pcs-handle
property.
Update and provide a .get/set_link_ksettings function that use phylink
for ethtool OPs now that we fully support phylink.

From: Zhixing Chen @ 2026-06-18 12:58 UTC (permalink / raw)

ip6t_ah checks that the fixed AH header is present, then uses hdrlen to
derive the advertised AH header length for matching.
Return false if the skb does not contain the advertised AH header length.
This avoids matching AH headers whose advertised length is not present in
the skb.

I noticed ip6t_hbh and ip6t_rt already do this advertised-length check
for their IPv6 extension headers, so this keeps ip6t_ah in line with
those matches.

## Form letter - net-next-closed
[adapted from text by Jakub]
A pull request for with net-next material for v7.2 has already been submitted,
and therefore net-next is closed for new drivers, features, code refactoring
and optimizations. We are currently accepting bug fixes only.
Please repost when net-next reopens after June 29th.
RFC patches sent for review only are obviously welcome at any time.

Using a spin_lock seems overkill here to me since airoha_mac_link_up()
run in the process context and the spin_lock you are acquiring here
was just used for stats. Since mac_link_up is running in some cases
acquiring RTNL, I guess you can even do something like:
bool rtnl = rtnl_is_locked();
if (!rtnl)
rtnl_lock();
...
if (!rtnl)
rtnl_unlock();

net/mlx5e: macsec: fix use-after-free of metadata_dst on RX SC delete
This commit fixes a use-after-free in the MACsec RX datapath by replacing
a synchronous metadata_dst_free() with dst_release() when an RX SC is
deleted. It also updates the datapath to use dst_hold_safe() to avoid
acquiring a reference to a dying destination entry.

[Severity: Critical]
This is a pre-existing issue, but is it safe to synchronously call kfree()
on rx_sc->sc_xarray_element here?
The RX datapath accesses the xarray under rcu_read_lock() in
mlx5e_macsec_offload_handle_rx_skb(). If sc_xarray_element is fetched via
xa_load() by a concurrent reader just before xa_erase() runs, won't this
kfree() free the element while the reader is still accessing it, leading to
a use-after-free?

[Severity: Critical]
This isn't a bug introduced by this patch, but does xa_load() return NULL
if the fs_id has already been erased by xa_erase() in the deletion path?
If packets matched by hardware before the rule was deleted are still
lingering in the software RX queues, xa_load() might return NULL.
Dereferencing sc_xarray_element->rx_sc immediately after could cause a
NULL pointer dereference. Could we add a NULL check here before accessing
sc_xarray_element?
[Severity: Critical]
This is also a pre-existing issue, but is rx_sc fully initialized when it
becomes visible to RCU readers?
In mlx5e_macsec_add_rxsc(), it appears sc_xarray_element is published to
the xarray via xa_alloc() before rx_sc->md_dst is allocated and
initialized:
mlx5e_macsec_add_rxsc() {
...
err = xa_alloc(&macsec->sc_xarray, &sc_xarray_element->fs_id, ...);
...
rx_sc->md_dst = metadata_dst_alloc(0, METADATA_MACSEC, GFP_KERNEL);
...
}
Since xa_alloc() assigns the lowest available index, the new fs_id could be
recycled from a recently deleted SC. If a lingering packet with the old
fs_id is processed by the datapath, it could find the newly published
element and attempt to call dst_hold_safe(&rx_sc->md_dst->dst).
Because rx_sc->md_dst is still NULL at that moment, could this cause a NULL
pointer dereference?

My comment that the files should be renamed now instead of later when
support for other airoha platforms are added still stands. The common
code is not common among other platforms (EN7523 as example).

From: Thorsten Leemhuis @ 2026-06-18 13:39 UTC (permalink / raw)

Hi Jakub, Donald! During the past few weeks I two or three times ran
into errors when building ynl as part of my daily -mainline/-next builds
based on a srpm pretty close to the kernel srpm used in Fedora rawhide.
Today I for example ran into this:
"""

"""
DRM_RAS_CMD_CLEAR_ERROR_COUNTER was introduced to mainline yesterday as
ee18d39a087792 ("drm/drm_ras: Add clear-error-counter netlink command to
drm_ras") [v7.1-post].
I finally looked closer today and noticed how to prevent this: update
the kernel's UAPI files (e.g. the stuff that lives in /usr/include/) on
the builder. Thing is: that's basically impossible to do from a srpm, as
those should not change the build environment and can't even when
working as non-root.
Note sure if relevant and just a shot in the dark, so maybe ignore the
following:
While investigating this I noticed this comment in
tools/net/ynl/Makefile.deps:
"""
> # Try to include uAPI headers from the kernel uapi/ path.
> # Most code under tools/ requires the respective kernel uAPI headers
> # to be copied to tools/include. The duplication is annoying.
> # All the family headers should be self-contained. We avoid the copying
> # by selectively including just the uAPI header of the family directly
> # from the kernel sources.
"""
Is that maybe not the case anymore with the recent changes to ynl?
Ciao, Thorsten

* [PATCH net v2 00/10] rxrpc: Miscellaneous fixes
From: David Howells @ 2026-06-18 13:47 UTC (permalink / raw)
To: netdev
Cc: David Howells, Marc Dionne, Jakub Kicinski, David S. Miller,
Eric Dumazet, Paolo Abeni, Simon Horman, linux-afs, linux-kernel
Here are some miscellaneous AF_RXRPC fixes for more stuff found by Sashiko[1][2]:
(1) Reject ACKALL packets for calls not in Tx or immediate post-Tx state.
(2) Fix connection leak from AF_RXRPC recvmsg userspace OOB handling.
(3) Fix double unlock in AF_RXRPC recvmsg userspace OOB handling.
(4) Fix AFS preallocate charge to flush the waitqueue after unlistening
the socket so that any charging thread that does manage to get started
will be waited for before socket destruction.
(5) Fix AFS OOB notify handling to cancel in-progress OOB notification
handling and then to flush the workqueue it's on.
(6) Fix handling of apparent reply reception before initial transmission
starts in client call.
(7) Fix OOB challenge leak in cleanup on notification failure.
(8) Fix infinite loop in recvmsg if OOB packet available, but no calls.
(9) Fix notify vs recvmsg race where notify thinks the call is already
queued.
(10) Fix MSG_PEEK call leak for calls with no content.

Changes
=======
ver #2)
- Addressed the Sashiko review[2] of ver #1.
- Added patches to fix more bugs that it found.
- Adjusted AFS preallocate charge cleanup to only cancel the preallocate
work item after unlistening rather than flushing the entire waitqueue
(which may be waiting on DNS lookup).
-

From: Wyatt Feng <bronzed_45_vested@icloud.com>
rxrpc_input_ackall() accepts ACKALL packets without checking whether
the call is in a state that can legitimately have outstanding transmit
buffers. A forged ACKALL can therefore reach a new service call in
RXRPC_CALL_SERVER_RECV_REQUEST before any reply packets have been
queued.
In that state call->tx_top is zero and call->tx_queue is NULL, so
rxrpc_rotate_tx_window() dereferences a NULL txqueue and triggers a
null-pointer dereference.
Fix rxrpc_input_ackall() to mirror the transmit-state gating already
used for normal ACK processing, and ignore ACKALL when there is no
outstanding transmit window to rotate.

When an afs network namespace is torn down, it cancels and waits for the
work item that keeps the preallocated rxrpc call/conn/peer queue charged
before disabling incoming (i.e. listen 0), but there's a small window in
which it can be requeued by an incoming call wending through the I/O
thread.
Fix this by flushing the workqueue on which the charger runs after reducing
the listen backlog to zero.

Fix rxrpc_receiving_reply() to handle the reception of an apparent reply
DATA packet before rxrpc has had a chance to send any request DATA packets
on a client call by checking to see if the call has been exposed yet by
sending the first packet.
Without this, rxrpc_rotate_tx_window() might oops.
Also fix rxrpc_rotate_tx_window() to handle the Tx queue being empty by
changing the do...while loop into a while loop, just in case a call is
abnormally terminated by an early reply before the last request packet is
transmitted.

* [PATCH net v2 09/10] rxrpc: Fix socket notification race

In-Reply-To: <20260618134802.2477777-1-dhowells@redhat.com>
There's a race between rxrpc_recvmsg() and rxrpc_notify_socket(), whereby
the latter's attempt to avoid disabling interrupts and taking the socket's
recvmsg_lock if the call is already queued may happen simultaneously with
the former's discarding of a call that has nothing queued.
Fix this by removing the shortcut. Note that this only affects userspace's
use of AF_RXRPC; the AFS filesystem driver doesn't use the socket queue.

Fix rxrpc_recvmsg() to also drop the ref it holds on an already-released
call if MSG_PEEK is in force (the function holds a ref on the call
irrespective of whether MSG_PEEK is specified or not).

The enable in resume is intentionally unconditional and idempotent
(writing MPIC_INT_CLEAR_MASK on an already unmasked IRQ is a no-op).

The enable_percpu_irq() from mvneta_poll is not "lost" — it never
gets a chance to execute. The sequence is:
1. mvneta_percpu_isr: disable_percpu_irq() + napi_schedule()
2. PM freezes kthreads (on PREEMPT_RT, softirq runs in kthread)
3. NAPI poll cannot run → enable_percpu_irq() is never called
4. mvneta_stop_dev → napi_disable(): cancels the scheduled poll
but does NOT execute the completion path (no enable_percpu_irq)
5. Resume → napi_enable(): resets NAPI state but MPIC stays masked
The unconditional enable in resume covers this case. When NAPI was
idle at suspend time, the extra enable is harmless.

Yun

led_classdev_register_ext() only reads init_data.devicename - it never
stores the pointer. However, the caller allocated devicename with
kasprintf() but never freed it, leaking the string memory.
Fix it with a stack buffer to avoid dynamic buffers completely.
