rxrpc: Fix bug due to prealloc collision
When userspace is using AF_RXRPC to provide a server, it has to preallocate
incoming calls and assign to them call IDs that will be used to thread
related recvmsg() and sendmsg() together. The preallocated call IDs will
automatically be attached to calls as they come in until the pool is empty.
To the kernel, the call IDs are just arbitrary numbers, but userspace can
use the call ID to hold a pointer to prepared structs. In any case, the
user isn't permitted to create two calls with the same call ID (call IDs
become available again when the call ends) and EBADSLT should result from
sendmsg() if an attempt is made to preallocate a call with an in-use call
ID.
However, the cleanup in the error handling will trigger both assertions in
rxrpc_cleanup_call() because the call isn't marked complete and isn't
marked as having been released.
Fix this by setting the call state in rxrpc_service_prealloc_one() and then
marking it as being released before calling the cleanup function.

net/sched: Abort __tc_modify_qdisc if parent class does not exist
Lion's patch [1] revealed an ancient bug in the qdisc API.
Whenever a user creates/modifies a qdisc specifying as a parent another
qdisc, the qdisc API will, during grafting, detect that the user is
not trying to attach to a class and reject. However grafting is
performed after qdisc_create (and thus the qdiscs' init callback) is
executed. In qdiscs that eventually call qdisc_tree_reduce_backlog
during init or change (such as fq, hhf, choke, etc), an issue
arises. For example, executing the following commands:
sudo tc qdisc add dev lo root handle a: htb default 2
sudo tc qdisc add dev lo parent a: handle beef fq
Qdiscs such as fq, hhf, choke, etc unconditionally invoke
qdisc_tree_reduce_backlog() in their control path init() or change() which
then causes a failure to find the child class; however, that does not stop
the unconditional invocation of the assumed child qdisc's qlen_notify with
a null class. All these qdiscs make the assumption that class is non-null.
The solution is ensure that qdisc_leaf() which looks up the parent
class, and is invoked prior to qdisc_create(), should return failure on
not finding the class.
In this patch, we leverage qdisc_leaf to return ERR_PTRs whenever the
parentid doesn't correspond to a class, so that we can detect it
earlier on and abort before qdisc_create is called.
net: ethernet: ti: am65-cpsw-nuss: Fix skb size by accounting for skb_shared_info
While transitioning from netdev_alloc_ip_align() to build_skb(), memory
for the "skb_shared_info" member of an "skb" was not allocated. Fix this
by allocating "PAGE_SIZE" as the skb length, accounting for the packet
length, headroom and tailroom, thereby including the required memory space
for skb_shared_info.
net: thunderx: avoid direct MTU assignment after WRITE_ONCE()
The current logic in nicvf_change_mtu() writes the new MTU to
netdev->mtu using WRITE_ONCE() before verifying if the hardware
update succeeds. However on hardware update failure, it attempts
to revert to the original MTU using a direct assignment
(netdev->mtu = orig_mtu)
which violates the intended of WRITE_ONCE protection introduced in
commit 1eb2cded45b3 ("net: annotate writes on dev->mtu from
ndo_change_mtu()")
Additionally, WRITE_ONCE(netdev->mtu, new_mtu) is unnecessarily
performed even when the device is not running.
Fix this by:
Only writing netdev->mtu after successfully updating the hardware.
Skipping hardware update when the device is down, and setting MTU
directly. Remove unused variable orig_mtu.
This ensures that all writes to netdev->mtu are consistent with
WRITE_ONCE expectations and avoids unintended state corruption
on failure paths.
atm: clip: Fix infinite recursive call of clip_push().
syzbot reported the splat below. [0]
This happens if we call ioctl(ATMARP_MKIP) more than once.
During the first call, clip_mkip() sets clip_push() to vcc->push(),
and the second call copies it to clip_vcc->old_push().
Later, when the socket is close()d, vcc_destroy_socket() passes
NULL skb to clip_push(), which calls clip_vcc->old_push(),
triggering the infinite recursion.
Let's prevent the second ioctl(ATMARP_MKIP) by checking
vcc->user_back, which is allocated by the first call as clip_vcc.
Note also that we use lock_sock() to prevent racy calls.

KVM: x86: avoid underflow when scaling TSC frequency
In function kvm_guest_time_update(), __scale_tsc() is used to calculate

a TSC value that is less than 1 would underflow to 0 and to an infinite

eventpoll: don't decrement ep refcount while still holding the ep mutex
Jann Horn points out that epoll is decrementing the ep refcount and then
doing a
mutex_unlock(&ep->mtx);
afterwards. That's very wrong, because it can lead to a use-after-free.
That pattern is actually fine for the very last reference, because the
code in question will delay the actual call to "ep_free(ep)" until after
it has unlocked the mutex.
But it's wrong for the much subtler "next to last" case when somebody
*else* may also be dropping their reference and free the ep while we're
still using the mutex.
Note that this is true even if that other user is also using the same ep
mutex: mutexes, unlike spinlocks, can not be used for object ownership,
even if they guarantee mutual exclusion.
A mutex "unlock" operation is not atomic, and as one user is still
accessing the mutex as part of unlocking it, another user can come in
and get the now released mutex and free the data structure while the
first user is still cleaning up.
See our mutex documentation in Documentation/locking/mutex-design.rst,
in particular the section [1] about semantics:
"mutex_unlock() may access the mutex structure even after it has
internally released the lock already - so it's not safe for
another context to acquire the mutex and assume that the
mutex_unlock() context is not using the structure anymore"
So if we drop our ep ref before the mutex unlock, but we weren't the
last one, we may then unlock the mutex, another user comes in, drops
_their_ reference and releases the 'ep' as it now has no users - all
while the mutex_unlock() is still accessing it.
Fix this by simply moving the ep refcount dropping to outside the mutex:
the refcount itself is atomic, and doesn't need mutex protection (that's
the whole _point_ of refcounts: unlike mutexes, they are inherently
about object lifetimes).

net: phy: smsc: Fix link failure in forced mode with Auto-MDIX
Force a fixed MDI-X mode when auto-negotiation is disabled to prevent
link instability.
When forcing the link speed and duplex on a LAN9500 PHY (e.g., with
`ethtool -s eth0 autoneg off ...`) while leaving MDI-X control in auto
mode, the PHY fails to establish a stable link. This occurs because the
PHY's Auto-MDIX algorithm is not designed to operate when
auto-negotiation is disabled. In this state, the PHY continuously
toggles the TX/RX signal pairs, which prevents the link partner from
synchronizing.
This patch resolves the issue by detecting when auto-negotiation is
disabled. If the MDI-X control mode is set to 'auto', the driver now
forces a specific, stable mode (ETH_TP_MDI) to prevent the pair
toggling. This choice of a fixed MDI mode mirrors the behavior the
hardware would exhibit if the AUTOMDIX_EN strap were configured for a
fixed MDI connection.

Override the hardware strap configuration for MDI-X mode to ensure a

PHY is determined by the AUTOMDIX_EN strap pin, but the driver has no
documented way to read its latched status.
This unpredictability means the driver cannot know if the PHY has
initialized with Auto-MDIX enabled or disabled, preventing it from
providing a reliable interface to the user.
This patch introduces a `config_init` hook that forces the PHY into a
known state by explicitly enabling Auto-MDIX.

net: phy: smsc: Fix Auto-MDIX configuration when disabled by strap
Correct the Auto-MDIX configuration to ensure userspace settings are
respected when the feature is disabled by the AUTOMDIX_EN hardware strap.
The LAN9500 PHY allows its default MDI-X mode to be configured via a
hardware strap. If this strap sets the default to "MDI-X off", the
driver was previously unable to enable Auto-MDIX from userspace.
When handling the ETH_TP_MDI_AUTO case, the driver would set the
SPECIAL_CTRL_STS_AMDIX_ENABLE_ bit but neglected to set the required
SPECIAL_CTRL_STS_OVRRD_AMDIX_ bit. Without the override flag, the PHY
falls back to its hardware strap default, ignoring the software request.
This patch corrects the behavior by also setting the override bit when
enabling Auto-MDIX. This ensures that the userspace configuration takes
precedence over the hardware strap, allowing Auto-MDIX to be enabled
correctly in all scenarios.

net: stmmac: Fix interrupt handling for level-triggered mode in DWC_XGMAC2
According to the Synopsys Controller IP XGMAC-10G Ethernet MAC Databook
v3.30a (section 2.7.2), when the INTM bit in the DMA_Mode register is set
to 2, the sbd_perch_tx_intr_o[] and sbd_perch_rx_intr_o[] signals operate
in level-triggered mode. However, in this configuration, the DMA does not
assert the XGMAC_NIS status bit for Rx or Tx interrupt events.
This creates a functional regression where the condition
if (likely(intr_status & XGMAC_NIS)) in dwxgmac2_dma_interrupt() will
never evaluate to true, preventing proper interrupt handling for
level-triggered mode. The hardware specification explicitly states that
"The DMA does not assert the NIS status bit for the Rx or Tx interrupt
events" (Synopsys DWC_XGMAC2 Databook v3.30a, sec. 2.7.2).
The fix ensures correct handling of both edge and level-triggered
interrupts while maintaining backward compatibility with existing
configurations. It has been tested on the hardware device (not publicly
available), and it can properly trigger the RX and TX interrupt handling
in both the INTM=0 and INTM=2 configurations.

Petr and Sebastian went down to the archive history (before Git) and
found the commit that broke it at [1] / [2] ("Don't relocate
non-allocated regions in modules.").
The second fix, reported and fixed by Petr (with additional cleanup),
resolves a memory leak by ensuring proper deallocation if module
loading fails.
We couldn't find a reproducer other than forcing it manually or
leveraging eBPF. So, I tested it by enabling error injection in the
codetag functions through the error path that produces the leak and
made it fail until execmem is unable to allocate more memory"

rxrpc: Fix over large frame size warning
Under some circumstances, the compiler will emit the following warning for
rxrpc_send_response():
net/rxrpc/output.c: In function 'rxrpc_send_response':
net/rxrpc/output.c:974:1: warning: the frame size of 1160 bytes is larger than 1024 bytes
This occurs because the local variables include a 16-element scatterlist
array and a 16-element bio_vec array. It's probably not actually a problem
as this function is only called by the rxrpc I/O thread function in a
kernel thread and there won't be much on the stack before it.
Fix this by overlaying the bio_vec array over the kvec array in the
rxrpc_local struct. There is one of these per I/O thread and the kvec
array is intended for pointing at bits of a packet to be transmitted,
typically a DATA or an ACK packet. As packets for a local endpoint are
only transmitted by its specific I/O thread, there can be no race, and so
overlaying this bit of memory should be no problem.

module: Make sure relocations are applied to the per-CPU section
The per-CPU data section is handled differently than the other sections.
The memory allocations requires a special __percpu pointer and then the
section is copied into the view of each CPU. Therefore the SHF_ALLOC
flag is removed to ensure move_module() skips it.
Later, relocations are applied and apply_relocations() skips sections
without SHF_ALLOC because they have not been copied. This also skips the
per-CPU data section.
The missing relocations result in a NULL pointer on x86-64 and very
small values on x86-32. This results in a crash because it is not
skipped like NULL pointer would and can't be dereferenced.
Such an assignment happens during static per-CPU lock initialisation
with lockdep enabled.
Allow relocation processing for the per-CPU section even if SHF_ALLOC is
missing.

====================
tcp: Correct signedness in skb remaining space calculation
Syzkaller reported a bug [1] where sk->sk_forward_alloc can overflow.
When we send data, if an skb exists at the tail of the write queue, the
kernel will attempt to append the new data to that skb. However, the code
that checks for available space in the skb is flawed:
'''
copy = size_goal - skb->len
'''
The types of the variables involved are:
'''
copy: ssize_t (s64 on 64-bit systems)
size_goal: int
skb->len: unsigned int
'''
Due to C's type promotion rules, the signed size_goal is converted to an
unsigned int to match skb->len before the subtraction. The result is an
unsigned int.
When this unsigned int result is then assigned to the s64 copy variable,
it is zero-extended, preserving its non-negative value. Consequently, copy
is always >= 0.
Assume we are sending 2GB of data and size_goal has been adjusted to a
value smaller than skb->len. The subtraction will result in copy holding a
very large positive integer. In the subsequent logic, this large value is
used to update sk->sk_forward_alloc, which can easily cause it to overflow.
The syzkaller reproducer uses TCP_REPAIR to reliably create this
condition. However, this can also occur in real-world scenarios. The
tcp_bound_to_half_wnd() function can also reduce size_goal to a small
value. This would cause the subsequent tcp_wmem_schedule() to set
sk->sk_forward_alloc to a value close to INT_MAX. Further memory
allocation requests would then cause sk_forward_alloc to wrap around and
become negative.

which raises the hard coded limit on the number of devices we can
support on one SPI bus since some FPGA based systems are running into
the existing limit. This is not a good solution but it's one suitable
for this point in the release cycle, we should dynamically size the
relevant data structures which I hope will happen in the next couple
of merge windows.

"Mostly a few lines fixed here and there except amd/isp4 which improves
swnodes relationships but that is a new driver not in any stable

The i2c/piix4 change is a effectively a revert of the commit 7e173eb82ae9 ("i2c: piix4: Make CONFIG_I2C_PIIX4 dependent on
CONFIG_X86") but that required moving the header out from arch/x86
