A wide variety of mostly CephFS fixes and cleanups, split between
changes that address edge cases (Sam, Xiubo, Matthew), efficiency improvements (Max) and AI-assisted hardening (Michael, Jeremy). One thing that stands out is Alex's change to how CephFS behaves in NEARFULL scenarios: the long-standing "make all writes synchronous" behavior has become opt-in. It was always somewhat controversial and doesn't make much sense for modern deployments; the new default is to continue normal operation (i.e. buffer writes as MDS allows, etc). The behavior in case the cluster reaches any FULL state remains the same as before. -----BEGIN PGP SIGNATURE----- iQFHBAABCgAxFiEEydHwtzie9C7TfviiSn/eOAIR84sFAmqRz9QTHGlkcnlvbW92 QGdtYWlsLmNvbQAKCRBKf944AhHzi/63CACpEmwY/3lOZ4M0IQV2UJqSWzNNtUDI Hdq7hosk5gRXP/gG1bV63i935Ibe/Sp6Cb/XkTRcrPIxy/1eky8PDZN3knPlPocM TMAdLKUOzzpmehqORWdVsEGSYIXuIfVhrey30pfHVLQc86orTj7worDZydYl8r3L K6nAM8gfcT9l9Sd4jtquaT61kqCcjXKPANlvUtt8oqniMRdpL63GnFHaU33n3XTE 5Dalh4YHtIL4gTA6xZLbZqOq+99QbmmqlqlMiwFNtrfpVtPO7HWHrEy61mYrKW7U Nr7HRF6X+MeUngZVI5AgrH5K6HtlE0SeHZt2XSKuMKGMG+I4dcygUcSr =F8+z -----END PGP SIGNATURE----- Merge tag 'ceph-for-7.3-rc1' of https://github.com/ceph/ceph-client Pull ceph updates from Ilya Dryomov: "A wide variety of mostly CephFS fixes and cleanups, split between changes that address edge cases (Sam, Xiubo, Matthew), efficiency improvements (Max) and AI-assisted hardening (Michael, Jeremy).

f2fs-for-7.3-rc1
In this round, key enhancements focus on reducing inode management memory
overhead, introducing resizable tail sections with unified pinned allocation,
and boosting I/O throughput via parallel multi-device flushes and asynchronous
f2fs_write_end_io() execution. We also add dynamic device alias reservations to
allow on-the-fly space donation from user partitions.
Alongside these features, critical bug fixes resolve folio race conditions,
lingering dirty flags, dentry and block counter leaks, and potential deadloops
in f2fs_fsync_node_pages(). Additional stability patches address error-path
handling across symlink, sync, and rename/unlink operations, prevent pinned file
fragmentation, and correct segment migration and free section accounting in
free_segment_range.
Enhancement:
- reduce memory footprint of ino management
- support dynamic reserve/release for device aliasing
- issue multi-device flushes in parallel
- add a way to run f2fs_write_end_io() asynchronously
- support resizable tail section and unify pinned allocation
Bug fix:
- fix to pass folio->index to f2fs_sanity_check_node_footer()
- fix folio_nr_pages() race after put in large folio invalidate
- fix to clear dirty flag on folio in error path
- accurately adjust free_sections during free_segment_range
- fix to avoid potential deadloop in f2fs_fsync_node_pages()
- fix the error path in symlink, device alias in rename/unlink,
f2fs_sync_fs,
- fix to migrate all curseg types during free_segment_range
- fix to avoid pinfile fragment on fragment:{block, segment} mode
- fix valid block count leak on data block allocation failure
- fix dentry folio leak in find_in_level
- reject overlapping move range after len expansion
- fix some bugs related to file pinning, GC functions, i_size.
And, the series includes a number of minor bug fixes.

Hi,
I had to think a lot how to put this into few paragraphs. I hope this will makes sense to you and I'm not too confusing. The bulk of this pull request are Ross Philipson's TPM enablers for the Trenchboot patch series. The commits expose TPM constants, and decouple and improve robustness of tpm_buf a bit in order to implement a minimal early TPM driver. Early boot code will call either SKINIT on AMD or GETSEC[SENTER] on Intel before jumping into kernel's entry point. They re-initalize TPM PCRs but leave up to the early boot code measure initrd, boot_params and Trenchboot associated metadata. The motivation here is just that we would want in future iterations of the series put our full focus to the x86 part of the review, and call it a day as per TPM changes. Further, even if Trenchboot turned out to be empty lottery the worst possible outcome for TPM driver is that things get cleaned up a bit.

====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for net:
1) Use DEBUG_NET_WARN_ON_ONCE() instead of WARN_ON() from the tproxy
datapath, a recent bug found a way to reach WARN_ON from datapath
due to insufficient validation of xt_TPROTO checkentry.
From Fernando F. Mancera.
2) Similar to previous patch to replace WARN_ON_ONCE by
DEBUG_NET_WARN_ON_ONCE() for connlimit. Not known issue, but
since this patch has been around for a while, let's merge it.
Also from Fernando.
3) Move nf_tables harware offload commit path after chain blob
and audit to reduce chances of leaving the hardware in
inconsistent state.
4) Add missing vzeroupper to nf_tables pipapo AVX2 to address
performace degradation to later user of SSE code,
from Eric Biggers.
5) Remove pr_debug() in x_tables extensions, a recent bogus found a
way to print a unsanitized string in xt_IDLETIMER, many of these
pr_debug() calls are there for historical reasons.
6) Use pr_info_ratelimited() in x_tables .checkentry.
7) Fix an imbalance in module refcount due to incorrect override
expression logic with sets. Remove unnecessary clone in control
plane, use the existing expressions provided by set or dynset
expression. Release override expressions only.
8) Tigthen nf_tables device name removal, it is possible to remove
prefix strings with exact device name. From Fernando F. Mancera.
9) Set on the set dead bit earlier, otherwise it is possible to
call .commit on deleted sets. This also addresses the
re-introduction of a bug.

inet: frags: strip GSO state from fragments before reassembly
A virtio_net_hdr (tun/tap, or AF_PACKET with PACKET_VNET_HDR) can mark an IPv4 or IPv6 fragment as GSO; nothing relates gso_type to frag_off. inet_frag_reasm_prepare()/inet_frag_reasm_finish() keep the first fragment's skb as the head of the reassembled datagram, including its shinfo->gso_size/gso_type/gso_segs, and chain the remaining fragments on frag_list with whatever linear/paged layout they arrived with. After ip_defrag() (ip_local_deliver(), nf_defrag_ipv4, ...) the reassembled skb therefore still claims to be GSO (SKB_GSO_DODGY), and the next software segmentation point - udp_rcv_segment() on local delivery, validate_xmit_skb(), or the ip_finish_output_gso() slow path - hands it to skb_segment(). skb_segment()'s frag_list walk assumes GRO-shaped input and hits one of its BUG_ON()s.

net/sched: sch_htb: limit htb_classify inner-class filter hops
htb_classify() follows each filter-selected inner class by switching
to cl->filter_list, but never bounds the number of hops. A filter on
an inner class can point back to itself or to another inner class that
points back, creating an infinite loop in the packet classification
path with the qdisc lock held and BH disabled — a soft lockup / panic
from a single packet.
Bound the traversal with a hop counter and drop the packet with a
rate-limited warning once the bound is exceeded. The counter is
incremented at the point the inner filter chain is picked up, after the
TC_ACT_* switch has consumed the classifier verdict, so a terminal
TC_ACT_QUEUED/STOLEN/TRAP on the last permitted chain still sets *qerr
to __NET_XMIT_STOLEN and the packet is not charged as a drop by this
qdisc or its parent.
The bound is TC_HTB_MAXDEPTH, taken from HTB's own parameters rather than
from the qdisc hierarchy depth limit. Class levels run from 0 to
TC_HTB_MAXDEPTH - 1, so a traversal that strictly descends in level can
take at most TC_HTB_MAXDEPTH hops. That descent is what a sane
configuration does, but it is assumed here rather than enforced:
htb_find() resolves a classid against every class in the qdisc, so a
filter may equally select a sibling or an ancestor. The normal
root -> inner -> leaf path takes a single hop, so the bound does not
affect legitimate classification.
htb_classify() can now return NULL irrespective of CONFIG_NET_CLS_ACT,
whereas previously every NULL return sat inside that ifdef. The NULL
handler in htb_enqueue() therefore cannot stay conditional either, so
drop the ifdef around it. This matches hfsc_enqueue(), which has always
handled a NULL class unconditionally. Without it, a kernel built
without actions would dereference a NULL class instead of dropping.
Conditions to recreate the bug:
- CONFIG_NET_SCHED, CONFIG_NET_SCH_HTB, CONFIG_NET_CLS_U32,
CONFIG_LOCKUP_DETECTOR.
- Create an HTB qdisc on a device (e.g. lo), add an inner class
1:1 with a leaf child 1:10, install a root u32 filter selecting
1:1, and an inner-class u32 filter on 1:1 also selecting 1:1.
- Send one packet (ping). On the unfixed kernel the classify loop
spins with the qdisc lock held; with softlockup_panic=1 it panics.
- Reachable from unprivileged user via unshare -Urn (CAP_NET_ADMIN).

selftests/net: packetdrill: add tcp_urg_ptr_retransmit
Drive a connection into urgent mode and force a multi-segment retransmit, checking that each retransmitted segment keeps its own urg_ptr. The test asserts the fixed behaviour: the hole is retransmitted as two independent skbs, each with its own urg_ptr (5001 and 4001) and no PSH. An unpatched kernel instead sends one super-skb whose GSO split copies urg_ptr onto the second segment and also sets PSH there, so on an unpatched kernel the mismatch shows up on the PSH bit (actual P.U ... urg 5001) before the urg_ptr: tcp_urg_ptr_retransmit.pkt:63: live packet field tcp_psh: expected: 0 (0x0) vs actual: 1 (0x1) script packet: .U 1001:2001(1000) ack 1 actual packet: P.U 1001:2001(1000) ack 1 win 1050 After the fix the retransmit carries a per-segment urg_ptr and the test passes.

tcp: fix corruption of urgent data on multi-segment retransmit
On the normal xmit path, while in urgent mode we refuse to build a
multi-segment TSO packet, so every segment gets its own urg_ptr:
/* tcp_write_xmit() */
limit = mss_now;
if (tso_segs > 1 && !tcp_urg_mode(tp))
limit = tcp_mss_split_point(...);
The retransmit path has no such guard. __tcp_retransmit_skb() builds a
segs > 1 skb and hands it to the GSO layer, which only advances th->seq
per segment and copies urg_ptr verbatim:
/* __tcp_retransmit_skb() */
len = cur_mss * segs; /* segs > 1, no urg_mode check */
...
/* tcp_gso_segment(): bumps seq only, urg_ptr is copied */
urg_ptr is an offset from the segment's own seq, so a copied value points
at a different place on each segment. The receiver rebuilds the absolute
urgent seq as seg.seq + urg_ptr, so it walks a moving urgent point instead
of the one OOB byte:
seg1 seq 1 urg_ptr 5001 -> urgent @ 5001 (ok)
seg2 seq 1001 urg_ptr 5001 -> urgent @ 6001 (wrong, +MSS)
seg3 seq 2001 urg_ptr 5001 -> urgent @ 7001 (wrong, +2*MSS)
The real OOB byte is never pointed at, so the receiver stops splicing it
out and delivers it as normal in-band data, corrupting the stream.
Guard the retransmit length like the xmit path: keep segs = 1 while in
urgent mode.

fec_ptp_init() is only called when fep->bufdesc_ex is available.
However, fec_probe() unconditionally calls fec_ptp_stop() on the

Check fep->bufdesc_ex before calling fec_ptp_stop() in both paths

slip: remove slip_hangup() to fix use-after-free in slip_receive_buf()
Jaeyoung Chung and Eulgyu Kim reported a slab-use-after-free read
in slip_receive_buf() when racing against tty hangup.
tty_ldisc_hangup() calls ld->ops->hangup() while holding only
a read lock on tty->ldisc_sem (via tty_ldisc_ref()).
Because slip_hangup() simply called slip_close(), it ran concurrently
with reader functions such as slip_receive_buf().
slip_close() unregisters and frees the net device and its private
struct slip, causing concurrent reader threads in slip_receive_buf()
to dereference freed memory.
Line discipline close() is already guaranteed to be called under
the write lock of tty->ldisc_sem during hangup processing
(in tty_ldisc_reinit() or tty_ldisc_kill()).
Remove slip_hangup() so teardown is serialized cleanly by slip_close().

net: bridge: mcast: fix use-after-free of a master VLAN's multicast context
br_multicast_toggle_one_vlan() clears BR_VLFLAG_MCAST_ENABLED under
br->multicast_lock before stopping a VLAN's multicast context. That is
the teardown handshake: lockless readers gate on the flag through
br_multicast_ctx_should_use() -> br_multicast_ctx_vlan_disabled(), so
once it is cleared under the lock no reader can arm the context again.
For a master VLAN the handshake never runs. __vlan_del() clears
BRIDGE_VLAN_INFO_BRENTRY before calling br_vlan_put_master(), so
br_multicast_toggle_one_vlan(masterv, false) returns early on
!br_vlan_is_brentry(vlan): the flag stays set and br->multicast_lock is
never taken. br_vlan_put_master() then drains the context in
br_multicast_ctx_deinit() and frees the VLAN through call_rcu(), while a
reader still inside rcu_read_lock() sees the context as enabled and
re-arms it. The port and port-VLAN branch of the function has no
br_vlan_is_brentry() test and flips the flag under br->multicast_lock,
so it is not affected.
The reader is the bridge transmit path. For a master VLAN
br_multicast_rcv() selects brmctx = &vlan->br_mcast_ctx with
pmctx = NULL, so IGMP sent to the bridge device re-arms the context's
timers after br_multicast_ctx_deinit() has already stopped them.

net/sched: bound qdisc_pkt_len to prevent qdisc soft lockup
qdisc_get_stab() accepts a user-supplied size table, and
__qdisc_calculate_pkt_len() amplifies qdisc_pkt_len() through the
overhead, the size-table data (u16), and size_log (up to
STAB_SIZE_LOG_MAX). A crafted stab can therefore set qdisc_pkt_len()
to ~1 GiB for an ordinary skb. Per-flow deficit schedulers such as
DRR and ETS replenish one quantum per loop iteration; with a tiny
quantum (1) they spin billions of times under the qdisc lock,
producing a soft lockup / RCU stall as illustrated by vega@nebusec.ai.
Cap the final qdisc_pkt_len() to QDISC_PKT_LEN_MAX so the size-table
amplification cannot drive deficit schedulers into an unbounded loop.
A legitimate size table (e.g. qfq's overhead 999999999, which is
handled by dropping) is still accepted.
Introduce cap QDISC_PKT_LEN_MAX (1 << 20) = 1 MiB which is well above
any legitimate single-skb wire length: the largest current skb->len
is GSO_MAX_SIZE (524280), and an ATM-style size table (53/48 cell tax)
amplifies that to ~578 KB, both comfortably below 1 MiB. At the same
time, 1 MiB bounds the deficit refill loop to ~1M iterations per
packet with quantum=1, which completes in a few milliseconds well
under the demonstrated softlockup threshold (~10^9 iterations).
Conditions to recreate the bug:
- CONFIG_NET_SCHED=y, CONFIG_NET_SCH_DRR=y (or CONFIG_NET_SCH_ETS=y).
- Attach a DRR (or ETS) root qdisc with a crafted TCA_STAB that
amplifies qdisc_pkt_len to ~1 GiB (e.g. size_log=15, data=[32768]).
- Add a class with a tiny quantum of 1 and send one small packet; the
deficit loop spins billions of times under the qdisc lock and trips
the softlockup detector (panic with kernel.softlockup_panic=1).
- Reachable as root or from an unprivileged user in a fresh user+net
namespace (unshare -Urn) with namespace-local CAP_NET_ADMIN.

net: dsa: mxl862xx: enable assisted learning on CPU port
The MxL862xx driver enables FDB isolation but does not enable assisted
learning on the CPU port. Consequently, MAC addresses learned through a
physical switch port are not updated in hardware when the corresponding
station moves to a foreign bridge port, such as a Wi-Fi interface.
The stale hardware FDB entry continues directing return traffic toward
the original physical port. Traffic entering that same port is then
filtered instead of being forwarded to the CPU and software bridge. This
causes downstream unicast traffic, including DHCP OFFER and ACK packets,
to disappear after a client roams to a local wireless interface. The
client eventually considers the connection unusable and disconnects.
Enable assisted CPU-port learning so DSA installs foreign bridge FDB
entries on the CPU port. This keeps the hardware FDB synchronized with
the software bridge and allows return traffic to reach locally attached
Wi-Fi clients after roaming.
Tested on a BPI R4 PRO with a MxL862xx switch and a BE14000 WiFi interface.
- Without patch, wired uplink on lan6 port (mxl path)
Wifi clients connect but roam away not getting DHCP offers
- Without patch, wired uplink on wan port (no mxl path)
Wifi clients connect and roam successfully
- With this patch, uplink on lan6 (mxl path)

net: stmmac: restore NET_IP_ALIGN in the RX DMA offset
Since the RX path was converted to zero-copy, the page pool page is handed to the stack directly as the skb head, and the offset the DMA engine writes at is what determines the alignment of the packet headers. Before the conversion the payload was copied into an skb obtained from napi_alloc_skb(), which reserves NET_SKB_PAD + NET_IP_ALIGN. The conversion moved the headroom into stmmac_rx_offset() but did not carry over NET_IP_ALIGN, so on architectures where NET_IP_ALIGN is 2 the IP header now lands misaligned: 64 (NET_SKB_PAD) + 14 (ethernet) + 20 (IP) = 98 Same for the XDP branch: 256 (XDP_PACKET_HEADROOM) + 14 (ethernet) + 20 (IP) = 290 On ARM32 this is fatal, because ldm and ldrd trap on unaligned addresses even when CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS is set.

net: stmmac: drop gso_enabled_types and rely on netdev features
The gso_enabled_types field is used by stmmac_xmit() to decide whether a
GSO skb should be passed to stmmac_tso_xmit(). It is updated in
stmmac_set_features() based solely on NETIF_F_TSO, so disabling IPv4
TSO while keeping IPv6 TSO (NETIF_F_TSO6) enabled zeroes the mask. As a
result IPv6 GSO frames, which the networking stack still generates since
NETIF_F_TSO6 is enabled, fall through to the non-TSO xmit path where
they are not handled.
The networking stack already manages the GSO logic: a GSO skb is only
delivered to the driver when the matching offload feature (NETIF_F_TSO,
NETIF_F_TSO6 or NETIF_F_GSO_UDP_L4) is enabled, otherwise the frame is
segmented in software before reaching ndo_start_xmit().
stmmac_features_check() also validates each GSO frame against the TSO
hardware constraints and falls back to software GSO when they are not met.
Drop the gso_enabled_types field and rely on skb_is_gso() in
stmmac_xmit() instead, which correctly routes IPv6 GSO frames to the TSO
path when NETIF_F_TSO is disabled. This also removes the data race
between stmmac_set_gso_types(), called from the feature-set path, and
the lockless read of gso_enabled_types in stmmac_xmit().

Merge branch 'net-stmmac-more-selftest-related-fixes'
Maxime Chevallier says: ==================== net: stmmac: More selftest related fixes This series addresses some (but not all) issues found while running the ethtool selftest on various stmmac platforms. As a reminder, ethtool selftest are run with 'ethtool -t ethX', and for stmmac the goal is to test hardware features and bugs from the IP integration in the platform. I've been running this on : - Altera CycloneV (dwmac-socfpga, dwmac1000 IP, v3.70a) - NXP imx8mp (dwmac-imx, dwmac4, v5.10a) - Allwinner H2S (dwmac-sun8i, dwmac1000) - Amlogic S905X3 (dwmac-meson8b, dwmac1000, v3.70a) - STM32mp157a (dwmac-stm32, dwmac4, v4.20a) - SiFive JH7110 (dwmac-starfive, dwmac4, v5.20) Here's the results before this series, noting that some bugs were already fixed, some are ongoing (cf. the IP proto patch here [1]) [1] : https://lore.kernel.org/netdev/20260825211748.360935-1-maxime.chevallier@bootlin.com/ Tests are OK if return is 0 or -95 (-EOPNOTSUPP), tests are KO otherwise Test imx socfpga sun8i meson8b stm32 starfive MAC Loopback 0 0 0 0 0 0 MMC Counters 0 0 -95 -22 0 -22 EEE -95 -95 -95 -95 -95 -95 Hash Filter MC 0 0 -95 0 0 0 Perfect Filter UC 0 0 0 0 0 0 MC Filter 0 0 -95 0 0 0 UC Filter 0 0 -95 -22 0 0 Flow Control -110 0 -110 0 0 -110 RSS -95 -95 -95 -95 -95 -95 VLAN Filtering -110 -95 -95 -95 -110 -110 VLAN Filtering (perf) -110 -95 -95 -95 -110 -110 Double VLAN Filter -110 -95 -95 -95 -110 -110 Double VLAN Filter (perf) -110 -95 -95 -95 -110 -110 Flexible RX Parser 0 -95 -95 -95 -95 -95 SA Insertion (desc) 0 -95 -95 -95 0 0 SA Replacement (desc) 0 -95 -95 -95 0 0 SA Insertion (reg 0 -95 -95 -95 0 0 SA Replacement (reg) 0 -95 -95 -95 0 0 VLAN TX Insertion -110 -95 -95 -95 -110 -110 SVLAN TX Insertion -110 -95 -95 -95 -110 -95 L3 DA Filtering 0 -95 -95 -95 -95 -95 L3 SA Filtering 0 -95 -95 -95 -95 -95 L4 DA TCP Filtering 0 -95 -95 -95 -95 -95 L4 SA TCP Filtering 0 -95 -95 -95 -95 -95 L4 DA UDP Filtering 0 -95 -95 -95 -95 -95 L4 SA UDP Filtering 0 -95 -95 -95 -95 -95 ARP Offload -95 -95 -95 -95 -110 -110 Jumbo Frame 0 0 0 0 0 0 Multichannel Jumbo 0 -95 -95 -95 -95 -95 Split Header -95 -95 -95 -95 -95 -95 TBS (ETF Scheduler) -95 -95 -95 -95 -95 -95 So, only sogfpga is all OK (in all fairness, it doesn't support much) Several issues : - MMC test failing on starfive and meson8b, solved by patch 1 MMC counters maintained by the MAC are optional, which one is implemented depends on how the IP is synthesized. On starfive and meson8b, the counter used by the selftest to validate the MMC counters feature isn't implemented. Solved by adding other counters in the validation step, kinda fragile as this doesn't guarantee this will work on all platforms. - Flow control test failing on starfive, imx8mp, sun8i, solved by patch 6 Turns out these platforms actually never emit any Pause frame, as they don't have enough room in their per-queue RX Fifo. They do correctly process RX Pause frames. The fix isn't to change the advertised pauseparams, as the pause negotiation process based on MAC capabilities doesn't allow us to say we "just" support RX pause, so let's just not run the Pause tests if the RX fifo is too small. - UC filter failing on meson8b, fixed by patches 2,3,4 and 5 This one is quite the rabbit hole, and is a combination of multiple issues. - Unicast filtering uses the same filter (perfect filter) to allow the primary MAC address and the secondary addresses (dev->uc) to flow through the interface. That means if we have say 64 slots in the perfect filter, only 63 can be used for the dev->uc list, as the first entry stores the MAC address. If the filter is full, we switch to UC promisc mode, were we let all UC frames flow. There's an off-by-one error in dwmac1000, dwmac4 and dwxgmac2. - The selftest itself needs an empty slot in the filter, so it has to check that sizeof(dev->uc) is $number_of_slots - 2 (one for primary MAC, one for the test). There's an off-by-two error in the selftest. - This leads to an interesting finding (not addressed by this series) : The size of the perfect filter isn't reported by the HW, so it comes from firmware (snps,perfect-filter-entries). A lot of platforms don't specify that in DT (e.g. imx8mp doesn't, it has 128 entries but the driver thinks there's only 1...). I've reached out to Synopsys to see if there's some sane default we could use on dwmac4, if anyone has a dwmac4 databook I'd appreciate if you could look this up, as I don't have access to them, I'm not a vendor... Otherwise, we'll have to patch all the .dtsi if we want to avoid going in UC promisc as soon as we add an entry in dev->uc. After this series, socfpga, starfive and sun8i are all OK :) Some issues are still out there, the VLAN filtering and tagging fails on imx8mp and stm32 (so, dwmac4) butI haven't got there yet. ARP offload doesn't work on stm32mp157a and starfive JH7110 either. ==================== Link: https://patch.msgid.link/20260826140500.616466-1-maxime.chevallier@bootlin.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

net: stmmac: selftests: Don't test flow control for small rx fifos
On dwmac1000, dwmac4 and dwxgmac, we only emit pause frames if there's
at least 4096 bytes in each queue's fifo.
The phylink mac capabilities are still MAC_ASYM_PAUSE | MAC_SYM_PAUSE as
otherwise we won't be able to negotiate 'rx on' pause. ASYM only will
prevent negotiating 'rx off tx on', while SYM only doesn't really
matche the reality (not symmetric if we can only do RX pause).

net: stmmac: selftests: Account for the UC filter list for filtering tests
On dwmac, one of the Unicast filter entries is used to store the local
HW addr. This means that we have to use promisc mode for any kind of
unicast filtering if we only have one slot in our unicast filter.
The number of slots available depends on how the IP is integrated, and
we can't autodiscover how many of these slots we have available, so
the DT property snps,perfect-filter-entries can be used to specify how
many are available.
Most IP variants default to 1 if this isn't specified, which is the case
for the amlogic variants (in this case, S905X3).
The stmmac selftests for UC filtering look if we have enough slots in
the filter to store the dev->uc list, but doesn't account for the
device's own MAC address. The dev->uc list's size we get with
netdev_uc_count() also doesn't account for the HW addr.
As the selftest only requires one available slot, in the case of
single-slot platforms, that means we erroneously consider we have enough
room for the test, when we actually don't, and the filtering test fails.

net: stmmac: selftests: Check multiple MMC counters
The MMC counters report MAC statistics. Multiple counters can be
enabled when the IP is integrated, however there's no way to know
exactly which ones. Un-implemented counters seem to report 0.
It was found that on StarFive JH7110 and Amlogic SM1, the counter that's
used by the selftest (mmc_tx_framecount_g) isn't implemented, triggering
an MMC selftest failure.
Both the above SoCs seem to implement mmc_rx_framecount_gb, let's use
this counter as well for MMC counter validation.
Note that this doesn't guarantee that we won't encounter the same issue
again if another IP implements yet another set of counters that don't
include that new one.
If the game of whack-a-mole with implemented counters becomes too hard to
maintain, we may simply consider removing the MMC selftest entirely.

Use this new VMA anonymous page offset tracking to eliminate index conflicts and lay the foundation for scalable CoW performance improvements. - "promote mapped executable folios after first usage for MGLRU" (Baolin Wang): Make MGLRU's protection of mapped executable file folios more reliable. Follow the classical LRU's logic, promoting mapped executable file folios after their first usage to give executable code a better chance to stay in memory and improve workload performance. - "mm: vmscan: fix node reclaim ignoring swappiness parameter" (Ridong Chen): Fix per-node proactive reclaim interface's ignoring the swappiness parameter when CONFIG_MEMCG is disabled by consolidating sc_swappiness() into a single function that checks proactive_swappiness regardless of kernel configuration. - "mm/vmscan: reduce lru_lock contention via vmstat-derived scan-balance cost" (Usama Arif): Reduce lru_lock contention in the reclaim path by deriving scan-balance costs from vmstat counters rather than lock-acquired producer updates. Read and decay these cost signals on the reclaim side under a dedicated per-lruvec lock, reducing total LRU lock wait time by over 60% without impacting scan throughput. - "zram: fix zram issues reported by sashiko" (Sergey Senozhatsky): Fix two low-risk zram bugs which Sashiko spotted in drive-by review. - "Honor XA_FLAGS_ACCOUNT in xas_split_alloc() and charge to folio's memcg" (Zi Yan): Fix xas_split_alloc() by enabling target folio memcg charging during splits and adding the missing __GFP_ACCOUNT flag for proper XArray node memory accounting. - "selftests/mm: use pattern matching in .gitignore" (Pratyush Mallick): Replace hardcoded binary names in selftests/mm/.gitignore with a generic pattern-matching rule to automatically ignore generated test files and avoid manual updates when adding new tests. - "mm/page_ext: remove pgdat_page_ext_init()" (Sang-Heon Jeon): Make the incompatibility between FLATMEM and NUMA explicit in mm/Kconfig and remove the unused pgdat_page_ext_init() function. - "zram: fix zstd error paths and add parameter validation" (Haoqin Huang): Clean up zram compression backends by removing redundant error cleanup, adding parameter and dictionary validation, auto-prefixing algorithm error logs, and resetting parameters prior to reinitialization. - "zram: fix stale scan bounds after reinitialization" (Longlong Xia): Prevent out-of-bounds slot accesses during concurrent zram resets by moving table scan bound calculations under dev_lock in writeback_store() and read_block_state(). - "add anon mTHP collapse test cases" (Baolin Wang): Extend selftests helper functions to support arbitrary page orders and add new test cases and options for mTHP collapse in khugepaged. - "selftests/mm: Handle unsupported and transient test conditions" (Muhammad Usama Anjum): Update MM selftests to report a SKIP status instead of a failure when required kernel or filesystem features are unsupported, while adding retry logic for transient page migration errors. - "mm/zswap: Fixes and improves the zswap shrink" (Hao Jia): Fix the missing zswap global shrinker when CONFIG_MEMCG is disabled and extend shrink_memcg() to support batch writeback for improved writeback efficiency. - "alloc_tag: introduce IOCTL-based filtering for MAP" (Suren Baghdasaryan): Introduce an IOCTL-based binary interface for memory allocation profiling that enables kernel-side filtering before per-CPU counter aggregation. This eliminates the text-parsing overhead of /proc/allocinfo and provides up to a 20x speedup by transferring only filtered allocation data to userspace. - "better block swap batching and a different take on swap_ops v5" (Christoph Hellwig): Refactor block swap I/O to use swap_iocb for batching instead of single-bio requests and rebase the swap_ops interface, achieving faster swap throughput during kernel builds. - "mm: kmemleak: reduce transient false positives by confirming leaks" (Catalin Marinas): Reduce false-positive kmemleak reports by combining two kmemleak enhancements that add a second confirmation scan and a configurable minimum unreferenced scan count module parameter. - "mm: kmemleak: default min_unref_scans to 2 for verbose kernels" (Breno Leitao): Auto-scanning kernels can generate false-positive memory leak reports on single scans, so this patch defaults min_unref_scans to 2 when CONFIG_DEBUG_KMEMLEAK_VERBOSE is enabled to require a second confirming scan. - "swap_ops updates" (Christoph Hellwig): Batching I/O for synchronous swap devices causes performance regressions and filesystem-based swap suffers from double-indirection overhead. This series resolves both issues by reintroducing per-folio writes for synchronous swap and allowing filesystems to directly export their own swap_ops. - "mm/khugepaged: several cleanups" (Nico Pache): khugepaged accumulated redundant state-checking patterns and outdated comments following mTHP integration.

selftests: net: Fix slow configurations in big_tcp_tunnels.sh
The combination of checksum offload disabled (that causes software GSO)
and a debug kernel is inherently slow. Depending on the CPU power and
load, RTT may increase, limiting sk_pacing_rate, so tcp_tso_autosize
caps SKBs at around 40 segments, and zero BIG TCP packets are produced.
Increase sysctl net.ipv4.tcp_min_tso_segs and set a bigger initial value
of CWND in these configurations to force BIG TCP.

selftests: net: Lower threshold with csum offload off in big_tcp_tunnels.sh
With checksum offload disabled, much fewer BIG TCP packets are generated
due to overall loss of throughput. Use a separate threshold in these
tests, which is 1/10 of the threshold set for the rest of tests.

selftests: net: Lower threshold on debug kernels for big_tcp_tunnels.sh
Debug kernels on upstream CI runners run slower and generate fewer BIG
TCP packets, making the test flaky on upstream CI runners. Lower the
default threshold for those kernels.

selftests: net: Wait for netserver to launch
Use wait_local_port_listen after starting netserver in
big_tcp_tunnels.sh to ensure it's listening when the test starts.

net: airoha: npu: fix missing streaming DMA mask
The driver calls dma_set_coherent_mask() but never dma_set_mask(),
leaving the streaming DMA mask at the bus default. On the non-coherent
EN7581 platform (Cortex-A53), this causes the NPU mailbox to hang
after approximately 41 calls when using streaming DMA mappings.
Replace dma_set_coherent_mask() with dma_set_mask_and_coherent() to
set both the streaming and coherent DMA masks, matching standard
driver practice.

of: fix out-of-bounds read in of_alias_scan() stem parser
The stem parser tests isdigit(*(end - 1)) before checking end > start
and so reads one byte before the property name when the name is empty
or all digits. Check the bound first.

selftests/arm64: Add MTE test config fragment
The arm64 selftest collection has no Kconfig fragment, so kernels built with the selftest requirements are not guaranteed to provide the support used by these tests. Add a fragment covering all tests in arm64.

selftests/arm64: Fix MTE prctl TAP plan
The MTE prctl test emits one result from check_basic_read() followed by
one result for each of the seven entries in mte_modes[]. However, the TAP
plan only accounts for the array entries, producing:
# Planned tests != run tests (7 != 8)
Include the basic read check in the plan so that all eight emitted results
are declared.
