Make calls to extend_vma() and find_extend_vma() fail if the write lock
is required.
To avoid making this a flag-day event, this still allows the old
read-locking case for the trivial situations, and passes in a flag to
say "is it write-locked". That way write-lockers can say "yes, I'm
being careful", and legacy users will continue to work in all the common
cases until they have been fully converted to the new world order.

.. and make x86 use it.
This basically extracts the existing x86 "find and expand faulting vma"
code, but extends it to also take the mmap lock for writing in case we
actually do need to expand the vma.
We've historically short-circuited that case, and have some rather ugly
special logic to serialize the stack segment expansion (since we only
hold the mmap lock for reading) that doesn't match the normal VM
locking.
That slight violation of locking worked well, right up until it didn't:
the maple tree code really does want proper locking even for simple
extension of an existing vma.
So extract the code for "look up the vma of the fault" from x86, fix it
up to do the necessary write locking, and make it available as a helper
function for other architectures that can use the common helper.
Note: I say "common helper", but it really only handles the normal
stack-grows-down case. Which is all architectures except for PA-RISC
and IA64. So some rare architectures can't use the helper, but if they
care they'll just need to open-code this logic.
It's also worth pointing out that this code really would like to have an
optimistic "mmap_upgrade_trylock()" to make it quicker to go from a
read-lock (for the common case) to taking the write lock (for having to
extend the vma) in the normal single-threaded situation where there is
no other locking activity.
But that _is_ all the very uncommon special case, so while it would be
nice to have such an operation, it probably doesn't matter in reality.
I did put in the skeleton code for such a possible future expansion,
even if it only acts as pseudo-documentation for what we're doing.

When memory.reclaim was introduced, it became the first case where
cgroup_reclaim() is true for the root cgroup. Johannes concluded [1] that
for most cases this is okay, except for one case. Historically, kswapd
would throttle reclaim on a node if a lot of pages marked for reclaim are
under writeback (aka the node is congested). This occurred by setting
LRUVEC_CONGESTED bit in lruvec->flags. The bit would be cleared when the
node is balanced.
Similarly, cgroup reclaim would set the same bit when an lruvec is
congested, and clear it on the way out of reclaim (to throttle local
reclaimers).
Before the introduction of memory.reclaim, the root memcg was the only
target of kswapd reclaim, and non-root memcgs were the only targets of
cgroup reclaim, so they would never interfere. Using the same bit for
both was fine. After memory.reclaim, it is possible for cgroup reclaim on
the root cgroup to clear the bit set by kswapd. This would result in
reclaim on the node to be unthrottled before the node is balanced.
Fix this by introducing separate bits for cgroup-level and node-level
congestion. kswapd can unthrottle an lruvec that is marked as congested
by cgroup reclaim (as the entire node should no longer be congested), but
not vice versa (to prevent premature unthrottling before the entire node
is balanced).

This wrapper for sg_set_page() lets drivers add folios to a scatterlist
more easily. We could, perhaps, do better by using a different page in
the folio if offset is larger than UINT_MAX, but let's hope we get a
better data structure than this before we need to care about such large
folios.

early_pfn_to_nid() is called frequently in init_reserved_page(), it
returns the node id of the PFN. These PFN are probably from the same
memory region, they have the same node id. It's not necessary to call
early_pfn_to_nid() for each PFN.
Pass nid to reserve_bootmem_region() and drop the call to
early_pfn_to_nid() in init_reserved_page(). Also, set nid on all reserved
pages before doing this, as some reserved memory regions may not be set
nid.
The most beneficial function is memmap_init_reserved_pages() if
CONFIG_DEFERRED_STRUCT_PAGE_INIT is enabled.
The following data was tested on an x86 machine with 190GB of RAM.
before:
memmap_init_reserved_pages() 67ms
after:
memmap_init_reserved_pages() 20ms

Dave Airlie reports that gcc-13.1.1 has started complaining about some
of the workqueue code in 32-bit arm builds:
kernel/workqueue.c: In function ‘get_work_pwq’:
kernel/workqueue.c:713:24: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
713 | return (void *)(data & WORK_STRUCT_WQ_DATA_MASK);
| ^
[ ... a couple of other cases ... ]
and while it's not immediately clear exactly why gcc started complaining
about it now, I suspect it's some C23-induced enum type handlign fixup in
gcc-13 is the cause.
Whatever the reason for starting to complain, the code and data types
are indeed disgusting enough that the complaint is warranted.
The wq code ends up creating various "helper constants" (like that
WORK_STRUCT_WQ_DATA_MASK) using an enum type, which is all kinds of
confused. The mask needs to be 'unsigned long', not some unspecified
enum type.
To make matters worse, the actual "mask and cast to a pointer" is
repeated a couple of times, and the cast isn't even always done to the
right pointer, but - as the error case above - to a 'void *' with then
the compiler finishing the job.
That's now how we roll in the kernel.
So create the masks using the proper types rather than some ambiguous
enumeration, and use a nice helper that actually does the type
conversion in one well-defined place.
Incidentally, this magically makes clang generate better code. That,
admittedly, is really just a sign of clang having been seriously
confused before, and cleaning up the typing unconfuses the compiler too.

The API functions are slightly changed, so that they can be used
without the direct access to snd_ump object. The allocation is done

Convert fman_dtsec, xilinx_axienet and pcs-lynx to pass the neg_mode
into phylink_mii_c22_pcs_config(). Where appropriate, drivers are
updated to have neg_mode passed into their pcs_config() and
pcs_link_up() functions. For other drivers, we just hoist the call
to phylink_pcs_neg_mode() to their pcs_config() method out of
phylink_mii_c22_pcs_config().

PCS have to work out whether they should enable PCS negotiation by
looking at the "mode" and "interface" arguments, and the Autoneg bit
in the advertising mask.
This leads to some complex logic, so lets pull that out into phylink
and instead pass a "neg_mode" argument to the PCS configuration and
link up methods, instead of the "mode" argument.
In order to transition drivers, add a "neg_mode" flag to the phylink
PCS structure to PCS can indicate whether they want to be passed the
neg_mode or the old mode argument.

Arm SCMI updates for v6.5
Couple of main additions :-
1. Support for multiple SMC/HVC transports for SCMI:
Some platforms need to support multiple SCMI instances within
a platform(more commonly in a VM). The same SMC/HVC FID is used with
all the instances. The platform or the hypervisor needs a way to
distinguish among SMC/HVC calls made from different instances.
This change adds support for passing shmem channel address as the
parameters in the SMC/HVC call. The address is split into 4KB-page
and offset for simiplicity.
2. Addition od SCMI v3.2 explicit powercap enable/disable support:
SCMI v3.2 specification introduces support to disable powercapping
as a whole on the desired zones.
This change adds the needed support to the core SCMI powercap protocol,
exposing enable/disable protocol operations and then wiring up the new
operartions in the related powercap framework helpers.

Big transfers might take a bit of time, too constraining timeouts might
lead to false positives. In order to simplify the drivers work and with
the goal of factorizing code in mind, let's add a helper that can be
used by any spi controller driver to derive a relevant per-transfer
timeout value.
The logic is simple: we know how much time it would take to transfer a
byte, we can easily derive the total theoretical amount of time involved
for each transfer. We multiply it by two to have a bit of margin and
enforce a minimum of 500ms.

Netfilter/IPVS fixes for net
This is v3, including a crash fix for patch 01/14.
The following patchset contains Netfilter/IPVS fixes for net:
1) Fix UDP segmentation with IPVS tunneled traffic, from Terin Stock.
2) Fix chain binding transaction logic, add a bound flag to rule
transactions. Remove incorrect logic in nft_data_hold() and
nft_data_release().
3) Add a NFT_TRANS_PREPARE_ERROR deactivate state to deal with releasing
the set/chain as a follow up to 1240eb93f061 ("netfilter: nf_tables:
incorrect error path handling with NFT_MSG_NEWRULE")
4) Drop map element references from preparation phase instead of
set destroy path, otherwise bogus EBUSY with transactions such as:
flush chain ip x y
delete chain ip x w
where chain ip x y contains jump/goto from set elements.
5) Pipapo set type does not regard generation mask from the walk
iteration.
6) Fix reference count underflow in set element reference to
stateful object.
7) Several patches to tighten the nf_tables API:
- disallow set element updates of bound anonymous set
- disallow unbound anonymous set/chain at the end of transaction.
- disallow updates of anonymous set.
- disallow timeout configuration for anonymous sets.
8) Fix module reference leak in chain updates.
9) Fix nfnetlink_osf module autoload.
10) Fix deletion of basechain when NFTA_CHAIN_HOOK is specified as
in iptables-nft.
This Netfilter batch is larger than usual at this stage, I am aware we
are fairly late in the -rc cycle, if you prefer to route them through
net-next, please let me know.

Introduce a method to calculate the exact size in bits of a CAN(-FD)
frame with or without dynamic bitstuffing.
These are all the possible combinations taken into account:
- Classical CAN or CAN-FD
- Standard or Extended frame format
- CAN-FD CRC17 or CRC21
- Include or not intermission
Instead of doing several individual macro definitions, declare the
can_frame_bits() function-like macro. To this extent, do a full
refactoring of the length definitions.
In addition add the can_frame_bytes(). This function-like macro
replaces the existing macro:
- CAN_FRAME_OVERHEAD_SFF: can_frame_bytes(false, false, 0)
- CAN_FRAME_OVERHEAD_EFF: can_frame_bytes(false, true, 0)
- CANFD_FRAME_OVERHEAD_SFF: can_frame_bytes(true, false, 0)
- CANFD_FRAME_OVERHEAD_EFF: can_frame_bytes(true, true, 0)
Function-like macros were chosen over inline functions because they
can be used to initialize const struct fields.
The different maximum frame lengths (maximum data length, including
intermission) are as follow:
Frame type bits bytes
-------------------------------------------------------
Classic CAN SFF no bitstuffing 111 14
Classic CAN EFF no bitstuffing 131 17
Classic CAN SFF bitstuffing 135 17
Classic CAN EFF bitstuffing 160 20
CAN-FD SFF no bitstuffing 579 73
CAN-FD EFF no bitstuffing 598 75
CAN-FD SFF bitstuffing 712 89
CAN-FD EFF bitstuffing 736 92
The macro CAN_FRAME_LEN_MAX and CANFD_FRAME_LEN_MAX are kept as an
alias to, respectively, can_frame_bytes(false, true, CAN_MAX_DLEN) and
can_frame_bytes(true, true, CANFD_MAX_DLEN).
In addition to the above:
- Use ISO 11898-1:2015 definitions for the names of the CAN frame
fields.
- Include linux/bits.h for use of BITS_PER_BYTE.
- Include linux/math.h for use of mult_frac() and
DIV_ROUND_UP(). N.B: the use of DIV_ROUND_UP() is not new to this
patch, but the include was previously omitted.
- Add copyright 2023 for myself.

The CAN-FD frames only have one reserved bit. The bit corresponding to
Classical CAN frame's RTR bit is called the "Remote Request
Substitution (RRS)" [1].
N.B. The RRS is not to be confused with the Substitute Remote Request
(SRR).
Fix the description in the CANFD_FRAME_OVERHEAD_SFF/EFF macros.
The total remains unchanged, so this is just a documentation fix.
In addition to the above add myself as copyright owner for 2020 (as
coauthor of the initial version, c.f. Fixes tag).

The Stuff Bit Count is always coded on 4 bits [1]. Update the Stuff
Bit Count size accordingly.
In addition, the CRC fields of CAN FD Frames contain stuff bits at
fixed positions called fixed stuff bits [2]. The CRC field starts with
a fixed stuff bit and then has another fixed stuff bit after each
fourth bit [2], which allows us to derive this formula:
FSB count = 1 + round_down(len(CRC field)/4)
The length of the CRC field is [1]:
len(CRC field) = len(Stuff Bit Count) + len(CRC)
= 4 + len(CRC)
with len(CRC) either 17 or 21 bits depending of the payload length.
In conclusion, for CRC17:
FSB count = 1 + round_down((4 + 17)/4)
= 6
and for CRC 21:
FSB count = 1 + round_down((4 + 21)/4)
= 7
Add a Fixed Stuff bits (FSB) field with above values and update
CANFD_FRAME_OVERHEAD_SFF and CANFD_FRAME_OVERHEAD_EFF accordingly.
[1] ISO 11898-1:2015 section 10.4.2.6 "CRC field":
The CRC field shall contain the CRC sequence followed by a recessive
CRC delimiter. For FD Frames, the CRC field shall also contain the
stuff count.
Stuff count
If FD Frames, the stuff count shall be at the beginning of the CRC
field. It shall consist of the stuff bit count modulo 8 in a 3-bit
gray code followed by a parity bit [...]
[2] ISO 11898-1:2015 paragraph 10.5 "Frame coding":
In the CRC field of FD Frames, the stuff bits shall be inserted at
fixed positions; they are called fixed stuff bits. There shall be a
fixed stuff bit before the first bit of the stuff count, even if the
last bits of the preceding field are a sequence of five consecutive
bits of identical value, there shall be only the fixed stuff bit,
there shall not be two consecutive stuff bits. A further fixed stuff
bit shall be inserted after each fourth bit of the CRC field [...]

Some user-space applications want to monitor the subflows utilization.
Dumping the per subflow tcp_info is not enough, as the PM could close
and re-create the subflows under-the-hood, fooling the accounting.
Even checking the src/dst addresses used by each subflow could not
be enough, because new subflows could re-use the same address/port of
the just closed one.
This patch introduces a new socket option, allow dumping all the relevant
information all-at-once (everything, everywhere...), in a consistent
manner.

Currently there are no data transfer counters accounting for all
the subflows used by a given MPTCP socket. The user-space can compute
such figures aggregating the subflow info, but that is inaccurate
if any subflow is closed before the MPTCP socket itself.
Add the new counters in the MPTCP socket itself and expose them
via the existing diag and sockopt. While touching mptcp_diag_fill_info(),
acquire the relevant locks before fetching the msk data, to ensure
better data consistency

When calling bpf_sk_lookup_tcp(), bpf_sk_lookup_udp() or
bpf_skc_lookup_tcp() from tc/xdp ingress, VRF socket bindings aren't
respoected, i.e. unbound sockets are returned, and bound sockets aren't
found.
VRF binding is determined by the sdif argument to sk_lookup(), however
when called from tc the IP SKB control block isn't initialized and thus
inet{,6}_sdif() always returns 0.
Fix by calculating sdif for the tc/xdp flows by observing the device's
l3 enslaved state.
The cg/sk_skb hooking points which are expected to support
inet{,6}_sdif() pass sdif=-1 which makes __bpf_skc_lookup() use the
existing logic.

Qualcomm driver updates for v6.5
Konrad Dybcio is promoted, from reviewer, to co-maintainer.
The mdt_loader gets a fix to the detection of split binaries, where the
previous logic sometimes concluded that the first segments was not
split, in a split image. The unconditional calling of
scm_pas_mem_setup() turns out to cause a regression and is reverted.
The altmode subfunction of pmic_glink is enabled for SM8450.
A new driver for exposing power statistics from the RPM, for debugging
purposes, is introduced.
OCMEM gets a debug prints of the hardware version, QMI helpers are
transitioned to alloc_ordered_workqueue() and an error message in
ramp_controller is improved.
An API is introduced to the SMEM driver to allow other drivers to query
the SoC id, rather than open-coding the parsing of the relevant SMEM
item. This is then used to clean up the Qualcomm NVMEM-based cpufreq
driver.
Socinfo is extended with knowledge about IPQ5018, IPQ5312 and IPQ5302.
