Commit fa3bea4e1f82 introduced MPOL_WEIGHTED_INTERLEAVE but it missed
adding its counter to "interleave_hit" of numastat, which is located at
/sys/devices/system/node/nodeN/ directory.
It'd be better to add weighted interleving counter info to the existing
"interleave_hit" instead of introducing a new counter
"weighted_interleave_hit".

Since commit bdf8eafbf7f5 ("arm64: stacktrace: report source of unwind
data") a stack trace line can contain an additional info field that was not
present before, in the form of one or more letters in parentheses. E.g.:
[ 504.517915] led_sysfs_enable+0x54/0x80 (P)
^^^
When this is present, decode_stacktrace decodes the line incorrectly:
[ 504.517915] led_sysfs_enable+0x54/0x80 P
Extend parsing to decode it correctly:
[ 504.517915] led_sysfs_enable (drivers/leds/led-core.c:455 (discriminator 7)) (P)
The regex to match such lines assumes the info can be extended in the
future to other uppercase characters, and will need to be extended in case
other characters will be used. Using a much more generic regex might incur
in false positives, so this looked like a good tradeoff.

The recently added WARN() for deprecated #address-cells and #size-cells
triggered a WARN when of_platform_populate() (which calls
of_address_to_resource()) is used on nodes with non-translatable
addresses. This case is expected to return an error.
Rework the bus matching to allow no match and make the default require
an #address-cells property. That should be safe to do as any platform
missing #address-cells would have a warning already.

The new __kvm_faultin_pfn() function is upset by the fact that e500
KVM ignores host page permissions - __kvm_faultin requires a "writable"
outgoing argument, but e500 KVM is passing NULL.
While a simple fix would be possible that simply allows writable to
be NULL, it is quite ugly to have e500 KVM ignore completely the host
permissions and map readonly host pages as guest-writable. Merge a more
complete fix and remove the VMA-based attempts at building huge shadow TLB
entries. Using a PTE lookup, similar to what is done for x86, is better
and works with remap_pfn_range() because it does not assume that VM_PFNMAP
areas are contiguous. Note that the same incorrect logic is there in
ARM's get_vma_page_shift() and RISC-V's kvm_riscv_gstage_ioremap().
Fortunately, for e500 most of the code is already there; it just has to
be changed to compute the range from find_linux_pte()'s output rather
than find_vma(). The new code works for both VM_PFNMAP and hugetlb
mappings, so the latter is removed.
Patches 2-5 were tested by the reporter, Christian Zigotzky. Since
the difference with v1 is minimal, I am going to send it to Linus
today.

e500 KVM tries to bypass __kvm_faultin_pfn() in order to map VM_PFNMAP
VMAs as huge pages. This is a Bad Idea because VM_PFNMAP VMAs could
become noncontiguous as a result of callsto remap_pfn_range().
Instead, use the already existing host PTE lookup to retrieve a
valid host-side mapping level after __kvm_faultin_pfn() has
returned. Then find the largest size that will satisfy the
guest's request while staying within a single host PTE.

Add the possibility of marking a page so that the UW and SW bits are

kvmppc_e500_ref_setup is returning whether the guest TLB entry is writable,
which is than passed to kvm_release_faultin_page. This makes little sense
for two reasons: first, because the function sets up the private data for
the page and the return value feels like it has been bolted on the side;
second, because what really matters is whether the _shadow_ TLB entry is
writable. If it is not writable, the page can be released as non-dirty.
Shift from using tlbe_is_writable(gtlbe) to doing the same check on
the shadow TLB entry.

If find_linux_pte fails, IRQs will not be restored. This is unlikely

-> dev_queue_xmit
-> __dev_queue_xmit
-> netdev_core_pick_tx
-> skb_tx_hash
When device is unregistering, the 'dev->real_num_tx_queues' goes to
zero and the 'while (unlikely(hash >= qcount))' loop inside the
'skb_tx_hash' becomes infinite, locking up the core forever.
But unfortunately, checking just the carrier status is not enough to
fix the issue, because some devices may still be in unregistering
state while reporting carrier status OK.
One example of such device is a net/dummy. It sets carrier ON
on start, but it doesn't implement .ndo_stop to set the carrier off.
And it makes sense, because dummy doesn't really have a carrier.
Therefore, while this device is unregistering, it's still easy to hit
the infinite loop in the skb_tx_hash() from the OVS datapath. There
might be other drivers that do the same, but dummy by itself is
important for the OVS ecosystem, because it is frequently used as a
packet sink for tcpdump while debugging OVS deployments. And when the
issue is hit, the only way to recover is to reboot.
Fix that by also checking if the device is running. The running
state is handled by the net core during unregistering, so it covers
unregistering case better, and we don't really need to send packets
to devices that are not running anyway.
While only checking the running state might be enough, the carrier
check is preserved. The running and the carrier states seem disjoined
throughout the code and different drivers. And other core functions
like __dev_direct_xmit() check both before attempting to transmit
a packet. So, it seems safer to check both flags in OVS as well.

When tx_max_frame_size was added to struct ravb_hw_info, no value was
set in ravb_rzv2m_hw_info so the default value of zero was used.
The maximum MTU is set by subtracting from tx_max_frame_size to allow
space for headers and frame checksums. As ndev->max_mtu is unsigned,
this subtraction wraps around leading to a ridiculously large positive
value that is obviously incorrect.
Before tx_max_frame_size was introduced, the maximum MTU was based on
rx_max_frame_size. So, we can restore the correct maximum MTU by copying
the rx_max_frame_size value into tx_max_frame_size for RZ/V2M.

In mana_driver_exit(), mana_debugfs_root gets cleanup before any of it's
children (which happens later in the pci_unregister_driver()).
Due to this, when mana driver is configured as a module and rmmod is
invoked, following stack gets printed along with failure in rmmod command.

Commit 86e25f40aa1e ("net: napi: Add napi_config") moved napi->napi_id
assignment to a later point in time (napi_hash_add_with_id). This breaks
__xdp_rxq_info_reg which copies napi_id at an earlier time and now
stores 0 napi_id. It also makes sk_mark_napi_id_once_xdp and
__sk_mark_napi_id_once useless because they now work against 0 napi_id.
Since sk_busy_loop requires valid napi_id to busy-poll on, there is no way
to busy-poll AF_XDP sockets anymore.
Bring back the ability to busy-poll on XSK by resolving socket's napi_id
at bind time. This relies on relatively recent netif_queue_set_napi,
but (assume) at this point most popular drivers should have been converted.
This also removes per-tx/rx cycles which used to check and/or set
the napi_id value.
Confirmed by running a busy-polling AF_XDP socket
(github.com/fomichev/xskrtt) on mlx5 and looking at BusyPollRxPackets
from /proc/net/netstat.

Recalculate features when XDP is detached.
Before:
# ip li set dev eth0 xdp obj xdp_dummy.bpf.o sec xdp
# ip li set dev eth0 xdp off
# ethtool -k eth0 | grep gro
rx-gro-hw: off [requested on]
After:
# ip li set dev eth0 xdp obj xdp_dummy.bpf.o sec xdp
# ip li set dev eth0 xdp off
# ethtool -k eth0 | grep gro
rx-gro-hw: on
The fact that HW-GRO doesn't get re-enabled automatically is just
a minor annoyance. The real issue is that the features will randomly
come back during another reconfiguration which just happens to invoke
netdev_update_features(). The driver doesn't handle reconfiguring
two things at a time very robustly.
Starting with commit 98ba1d931f61 ("bnxt_en: Fix RSS logic in
__bnxt_reserve_rings()") we only reconfigure the RSS hash table
if the "effective" number of Rx rings has changed. If HW-GRO is
enabled "effective" number of rings is 2x what user sees.
So if we are in the bad state, with HW-GRO re-enablement "pending"
after XDP off, and we lower the rings by / 2 - the HW-GRO rings
doing 2x and the ethtool -L doing / 2 may cancel each other out,
and the:
if (old_rx_rings != bp->hw_resc.resv_rx_rings &&
condition in __bnxt_reserve_rings() will be false.
The RSS map won't get updated, and we'll crash with:

As pointed out in the original comment, lookup in sockmap can return a TCP

set before it was ESTABLISHED. In other words, a non-NULL sk_reuseport_cb
does not imply a non-refcounted socket.

automounting
In some cases, when password2 becomes the working password, the
client swaps the two password fields in the root session struct, but
not in the smb3_fs_context struct in cifs_sb. DFS automounts inherit
fs context from their parent mounts. Therefore, they might end up
getting the passwords in the stale order.
The automount should succeed, because the mount function will end up
retrying with the actual password anyway. But to reduce these
unnecessary session setup retries for automounts, we can sync the
parent context's passwords with the root session's passwords before
duplicating it to the child's fs context.

With the consolidation of put_prev_task/set_next_task(), see
commit 436f3eed5c69 ("sched: Combine the last put_prev_task() and the
first set_next_task()"), we are now skipping the transition between
these two functions when the previous and the next tasks are the same.
As a result, the scx idle state of a CPU is updated only when
transitioning to or from the idle thread. While this is generally
correct, it can lead to uneven and inefficient core utilization in
certain scenarios [1].
A typical scenario involves proactive wake-ups: scx_bpf_pick_idle_cpu()
selects and marks an idle CPU as busy, followed by a wake-up via
scx_bpf_kick_cpu(), without dispatching any tasks. In this case, the CPU
continues running the idle thread, returns to idle, but remains marked
as busy, preventing it from being selected again as an idle CPU (until a
task eventually runs on it and releases the CPU).
For example, running a workload that uses 20% of each CPU, combined with
an scx scheduler using proactive wake-ups, results in the following core
utilization:
CPU 0: 25.7%
CPU 1: 29.3%
CPU 2: 26.5%
CPU 3: 25.5%
CPU 4: 0.0%
CPU 5: 25.5%
CPU 6: 0.0%
CPU 7: 10.5%
To address this, refresh the idle state also in pick_task_idle(), during
idle-to-idle transitions, but only trigger ops.update_idle() on actual
state changes to prevent unnecessary updates to the scx scheduler and
maintain balanced state transitions.
With this change in place, the core utilization in the previous example
becomes the following:
CPU 0: 18.8%
CPU 1: 19.4%
CPU 2: 18.0%
CPU 3: 18.7%
CPU 4: 19.3%
CPU 5: 18.9%
CPU 6: 18.7%
CPU 7: 19.3%

DMEM cgroup pull request
This introduces a new cgroup controller to limit the device memory.
Notable users would be DRM, dma-buf heaps, or v4l2.
This pull request is based on the series developped by Maarten
Lankhorst, Friedrich Vock, and I:

With IORING_SETUP_SQPOLL all requests are created by the SQPOLL task,
which means that req->task should always match sqd->thread. Since
accesses to sqd->thread should be separately protected, use req->task
in io_req_normal_work_add() instead.
Note, in the eyes of io_req_normal_work_add(), the SQPOLL task struct
is always pinned and alive, and sqd->thread can either be the task or
NULL. It's only problematic if the compiler decides to reload the value
after the null check, which is not so likely.
