KVM: arm64: Use stage-1 leaf size for VM_PFNMAP
When commit 2aa53d68cee6 ("KVM: arm64: Try stage2 block mapping for
host device MMIO") added VM_PFNMAP support to get_vma_page_shift(),
stage-1 page tables did not support huge PFNMAP (as in VFIO-PCI
vfio_pci_mmap_huge_fault()) and transparent_hugepage_adjust() was
unsafe for MMIO as it dereferenced struct page.
Since commit 6011cf68c885 ("KVM: arm64: Walk userspace page tables to
compute the THP mapping size"), transparent_hugepage_adjust() instead
walks the host stage-1 page tables via get_user_mapping_size() without
touching struct page. Meanwhile, commit 3e509c9b03f9 ("mm/arm64:
support large pfn mappings") enabled stage-1 huge PFNMAP.
So. we can drop the VMA-based VM_PFNMAP size calculation in
get_vma_page_shift() and let transparent_hugepage_adjust() derive
the stage-2 mapping size directly from the populated stage-1 leaf
for non-cacheable mappings as well.

net: phy: aquantia: fix system interface type not updated in forced mode
aqr_gen1_read_status() decodes the MDIO_PHYXS_VEND_IF_STATUS register
to determine which SerDes interface the PHY is currently using on its
system side and stores the result in phydev->interface. phylink relies
on this value to configure the MAC.
The autoneg == AUTONEG_DISABLE check is not correct:
MDIO_PHYXS_VEND_IF_STATUS is set by the PHY firmware based on the
negotiated link speed, not based on whether autoneg was used to reach
it. When the link comes up at 1G in forced mode, the register correctly
reads SGMII, but the early return prevents phydev->interface from being
updated. It stays at whatever value it held before (typically 2500BASE-X
from the initial autoneg run), so phylink configures the MAC for the
wrong interface and the link cannot come up.
Remove the autoneg guard so that the system interface type is always
decoded when the link is up.

net: mvneta: clear XDP pfmemalloc flag between frames
mvneta_swbm_add_rx_fragment() sets XDP_FLAGS_FRAGS_PF_MEMALLOC on the
xdp_buff when a fragment page is a pfmemalloc one (page under memory
pressure). The xdp_buff is reused for the next frame, but only the
XDP_FLAGS_HAS_FRAGS bit was cleared at frame start, so the pfmemalloc
bit leaked from one frame into the following ones. mvneta_swbm_build_skb()
propagates the flag to skb->pfmemalloc through xdp_update_skb_frags_info(),
so the skb of a subsequent fragmented frame could be wrongly marked as
pfmemalloc even if none of its pages are under pressure.
Clear all the xdp_buff flags in mvneta_swbm_rx_frame(), which is invoked
for each new frame, instead of just the XDP_FLAGS_HAS_FRAGS bit.

r8169: disable EEE on RTL8168h/8111h
Force EEE off on the RTL8168h/8111h (RTL_GIGA_MAC_VER_46) at PHY connect
with phy_disable_eee().
Commit 202fef9bbbf5 ("net: phy: realtek: fix EEE advertisement write on
the internal PHY MMD path") made EEE actually advertise on the generic
Realtek PHY; the write had been a no-op before. On the RTL8168h that
un-masks a latent defect: once EEE negotiates, RX silently stalls after
~7-20 minutes. The carrier stays up, no counter or dmesg moves, and only
"ip link set down/up" recovers it; disabling EEE keeps the link stable.
Root-causing the RTL8168h LPI/RX path needs hardware not available now, so
disable EEE for this version. Use phy_disable_eee() rather than dropping
the version from rtl_supports_eee(): the latter also skips
rtl_enable_tx_lpi(), whose disable branch clears the MAC TX-LPI bits (ERI
0x1b0[1:0]) on link up. rtl_hw_start_8168h_1() does not clear them (the
RTL8402/RTL8106e init does), so a warm reboot from an EEE-active state
could otherwise leave TX-LPI asserted while the PHY no longer negotiates

octeontx2-pf: Fix RSS indirection table size
The conversion to the dedicated RSS context operations replaced the
pointer to struct otx2_rss_ctx with an inline u32 ind_tbl[] array.
However, otx2_rss_init() still uses sizeof(*rss->ind_tbl) to set rss_size.
This now yields the size of one u32 (4), rather than the 256 entries in
the indirection table.
The RSS initialization and hardware programming loops use rss_size,
so only four entries are initialized and programmed despite the NIX LF
being allocated a 256-entry table. On an OCTEON CN102 with eight RX
queues, the table contained 0, 1, 2, 3 followed by zeros. Traffic was
concentrated on queue 0 and ethtool -X equal 8 did not correct the table.
Use ARRAY_SIZE() to count the indirection table entries. On the same
hardware, this restores the full table repeating queue numbers 0 through
7, and bidirectional multi-flow traffic increments multiple RX queues.
Runtime testing on an Asterfusion ET2500 (OCTEON CN102 A0).

sctp: check RCV_SHUTDOWN after the sendmsg connect wait
sctp_wait_for_connect() drops the socket lock while it sleeps. An
out-of-the-blue ABORT can then be processed from the socket backlog and
unlink the association. If a concurrent shutdown(fd, SHUT_RD) sets
RCV_SHUTDOWN, the waiter breaks with err == 0 before checking
asoc->base.dead. Its final sctp_association_put() can then free the
association, leaving sctp_sendmsg_to_asoc() to continue with a dangling
pointer.
Check RCV_SHUTDOWN along with the wait error in sctp_sendmsg_to_asoc()
before using the association again. The check only accesses the socket,
so it needs no additional association reference. Return the existing
-ESRCH so that sctp_sendmsg() skips freeing a new association that may
already have been destroyed.
Keep sctp_wait_for_connect() unchanged to preserve its behavior for the
connect() caller.

net: sparx5: make ports inherit the switch base mac address type

0 is NET_ADDR_PERM, so userspace thinks this is a stable address.
With a random MAC reported as NET_ADDR_PERM, systemd's
MACAddressPolicy=persistent [1] leaves it unchanged, so a DHCP client
gets a new IP address every boot and a static reservation can't be used.
Reporting it as NET_ADDR_RANDOM makes systemd replace it with a stable
address derived from the interface name and machine-id.

crypto: aes - Fix undesired override of some optimized AES modes
The new library APIs for AES encryption modes were wired up to the
traditional crypto API via crypto/aes.c. However, for now the kernel is
still in a transitional state where various architectures still have
architecture-optimized implementations of AES modes in arch/*/crypto/,
wired up to the traditional crypto API only. Because of that, the
crypto/aes.c algorithms were given a cra_priority of only 110 to prevent
them from overriding arch/*/crypto/ in the traditional crypto API.
However, because of how the traditional crypto API works, the
cra_priority trick doesn't work in cases where the relevant algorithm
isn't directly implemented by arch/*/crypto/ but rather is provided by a
template instance using other code in arch/*/crypto/.
For example, x86 doesn't have its own "ccm(aes)" but rather relies on
the "ccm" template constructing it from the x86-optimized "ctr(aes)".
The existence of the library-based "ccm(aes)" prevents that, even though
its priority is lower than what the template would produce.

net: microchip: vcap: stop scanning after deleting key field
The only call outside the KUnit tests is in
sparx5_tc_add_rule_copy(), which passes a fixed key list with no
duplicate entries. Therefore, the potential double-free is not
currently reachable in tree.
However, vcap_filter_rule_keys() is exported and does not require its
key list entries to be unique. If a future or external caller supplies
the same key at another position that the inner loop visits, it calls
list_del() and kfree() a second time on the freed field, leading to a
potential double-free.
Break the inner loop after removing a matching field. The outer safe
list traversal continues to process the remaining rule fields.

netfilter: nft_flow_offload: drop flowtable reference on init error path
nft_flow_offload_init() bumps the flowtable use count with
nft_use_inc() before calling nf_ct_netns_get(). When the latter
fails, the error is returned as-is and the reference is leaked.
The upper layers do not balance it either: nf_tables_newexpr()
clears expr->ops when the expression init callback fails, so the
nft_expr_more() iteration in nft_rule_expr_deactivate() and
nf_tables_rule_destroy() stops right before the failed expression
and its ->destroy callback, which would drop the reference, never
runs.
Each failed rule addition therefore leaks one flowtable reference
and the flowtable can no longer be removed: NFT_MSG_DELFLOWTABLE
keeps reporting -EBUSY even though no rule references it.
Save the nf_ct_netns_get() return value and undo the nft_use_inc()
when it fails, restoring the inc/dec pairing within

netfilter: bpf: reject invalid NAT manipulation types
As bpf_ct_set_nat_info() is not validating the NAT manipulation type a

netfilter: flowtable: restore ieee80211 forward path
Before commit 871df5007eda ("netfilter: flowtable: bail out if forward
path cannot be discovered"), there was a fallback to set up a forward
path in case .ndo_fill_forward_path fails or DEV_PATH_MTK_WDMA was used.
Such fallback was used by commit d787a3e38f01 ("mac80211: add support
for .ndo_fill_forward_path").
One possibility is to handle DEV_PATH_MTK_WDMA from the flowtable
forward path discovery. However, this is only used internally by drivers
to retrieve mtk_wdma information to set up hardware offload. Felix
decided to use the .fill_forward_path interface for this purpose due to
the lack of a better interface at that time.
Add a new DEV_PATH_IEEE80211 path which is offered if the new ieee80211
flag is set on in the struct net_device_path_ctx to restore the
flowtable with a ieee80211 netdevice. Handle this new DEV_PATH_IEEE80211
path just like DEV_PATH_ETHERNET and DEV_PATH_DSA, ie. this is the last
netdevice in the stack.

netfilter: nft_set_rbtree: skip transaction elements during GC
Since nft_set_commit_update() runs set commit callbacks before processing
NEWSETELEM transactions, nft_rbtree_gc_scan() can observe elements added by
the transaction being committed.
The scan records an interval end in rbe_end without checking the element's
transaction state. A later, unrelated expired start then moves both
elements to the expired list. The synchronous GC queue can free the new end
element before the transaction subsequently activates it, causing a
use-after-free.
Only consider elements that are fully active in both generations. This
keeps transaction-state elements out of the GC scan and preserves interval
pairing across skipped elements.
