We currently push everyone to use padding to align 64b values
in netlink. Un-padded nla_put_u64() doesn't even exist any more.
The story behind this possibly start with this thread:
https://lore.kernel.org/netdev/20121204.130914.1457976839967676240.davem@davemloft.net/
where DaveM was concerned about the alignment of a structure
containing 64b stats. If user space tries to access such struct
directly:
struct some_stats *stats = nla_data(attr);
printf("A: %llu", stats->a);
lack of alignment may become problematic for some architectures.
These days we most often put every single member in a separate
attribute, meaning that the code above would use a helper like
nla_get_u64(), which can deal with alignment internally.
Even for arches which don't have good unaligned access - access
aligned to 4B should be pretty efficient.
Kernel and well known libraries deal with unaligned input already.
Padded 64b is quite space-inefficient (64b + pad means at worst 16B
per attr vs 32b which takes 8B). It is also more typing:
if (nla_put_u64_pad(rsp, NETDEV_A_SOMETHING_SOMETHING,
value, NETDEV_A_SOMETHING_PAD))
Create a new attribute type which will use 32 bits at netlink
level if value is small enough (probably most of the time?),
and (4B-aligned) 64 bits otherwise. Kernel API is just:
if (nla_put_uint(rsp, NETDEV_A_SOMETHING_SOMETHING, value))
Calling this new type "just" sint / uint with no specific size
will hopefully also make people more comfortable with using it.
Currently telling people "don't use u8, you may need the bits,
and netlink will round up to 4B, anyway" is the #1 comment
we give to newcomers.
In terms of netlink layout it looks like this:
0 4 8 12 16
32b: [nlattr][ u32 ]
64b: [ pad ][nlattr][ u64 ]
uint(32) [nlattr][ u32 ]
uint(64) [nlattr][ u64 ]

Extend the support to full range of min/max checks.
None of the existing YNL families required complex integer validation.
The support is less than trivial, because we try to keep struct nla_policy
tiny the min/max members it holds in place are s16. Meaning we can only
express checks in range of s16. For larger ranges we need to define
a structure and link it in the policy.

Pull networking fixes from Jakub Kicinski:
"Including fixes from bluetooth, netfilter, WiFi.
Feels like an up-tick in regression fixes, mostly for older releases.
The hfsc fix, tcp_disconnect() and Intel WWAN fixes stand out as
fairly clear-cut user reported regressions. The mlx5 DMA bug was
causing strife for 390x folks. The fixes themselves are not
particularly scary, tho. No open investigations / outstanding reports
at the time of writing.
Current release - regressions:
- eth: mlx5: perform DMA operations in the right locations, make
devices usable on s390x, again
- sched: sch_hfsc: upgrade 'rt' to 'sc' when it becomes a inner
curve, previous fix of rejecting invalid config broke some scripts
- rfkill: reduce data->mtx scope in rfkill_fop_open, avoid deadlock
- revert "ethtool: Fix mod state of verbose no_mask bitset", needs
more work
Current release - new code bugs:
- tcp: fix listen() warning with v4-mapped-v6 address
Previous releases - regressions:
- tcp: allow tcp_disconnect() again when threads are waiting, it was
denied to plug a constant source of bugs but turns out .NET depends
on it
- eth: mlx5: fix double-free if buffer refill fails under OOM
- revert "net: wwan: iosm: enable runtime pm support for 7560", it's
causing regressions and the WWAN team at Intel disappeared
- tcp: tsq: relax tcp_small_queue_check() when rtx queue contains a
single skb, fix single-stream perf regression on some devices
Previous releases - always broken:
- Bluetooth:
- fix issues in legacy BR/EDR PIN code pairing
- correctly bounds check and pad HCI_MON_NEW_INDEX name
- netfilter:
- more fixes / follow ups for the large "commit protocol" rework,
which went in as a fix to 6.5
- fix null-derefs on netlink attrs which user may not pass in
- tcp: fix excessive TLP and RACK timeouts from HZ rounding (bless
Debian for keeping HZ=250 alive)
- net: more strict VIRTIO_NET_HDR_GSO_UDP_L4 validation, prevent
letting frankenstein UDP super-frames from getting into the stack
- net: fix interface altnames when ifc moves to a new namespace
- eth: qed: fix the size of the RX buffers

The '$defs/ethernet-ports' schema is referenced by schemas defining a
child node 'ethernet-ports', but this schema misses the
'ethernet-ports' node. It would work if referring schemas made a
reference like this:
properties:
ethernet-ports:
$ref: ethernet-switch.yaml#/$defs/ethernet-ports
However, that would be different from how dsa.yaml works. For
consistency, align the schema definition with dsa.yaml and add the
missing level.

====================
mlx5-updates-2023-10-10
1) Adham Faris, Increase max supported channels number to 256
2) Leon Romanovsky, Allow IPsec soft/hard limits in bytes
3) Shay Drory, Replace global mlx5_intf_lock with
HCA devcom component lock
4) Wei Zhang, Optimize SF creation flow
During SF creation, HCA state gets changed from INVALID to
IN_USE step by step. Accordingly, FW sends vhca event to
driver to inform about this state change asynchronously.
Each vhca event is critical because all related SW/FW
operations are triggered by it.
Currently there is only a single mlx5 general event handler
which not only handles vhca event but many other events.
This incurs huge bottleneck because all events are forced
to be handled in serial manner.
Moreover, all SFs share same table_lock which inevitably
impacts each other when they are created in parallel.
This series will solve this issue by:
1. A dedicated vhca event handler is introduced to eliminate
the mutual impact with other mlx5 events.
2. Max FW threads work queues are employed in the vhca event
handler to fully utilize FW capability.
3. Redesign SF active work logic to completely remove
table_lock.
With above optimization, SF creation time is reduced by 25%,
i.e. from 80s to 60s when creating 100 SFs.
Patches summary:
Patch 1 - implement dedicated vhca event handler with max FW
cmd threads of work queues.
Patch 2 - remove table_lock by redesigning SF active work
logic.

TCP pingpong threshold is 1 by default. But some applications, like SQL DB
may prefer a higher pingpong threshold to activate delayed acks in quick
ack mode for better performance.
The pingpong threshold and related code were changed to 3 in the year
2019 in:
commit 4a41f453bedf ("tcp: change pingpong threshold to 3")
And reverted to 1 in the year 2022 in:
commit 4d8f24eeedc5 ("Revert "tcp: change pingpong threshold to 3"")
There is no single value that fits all applications.
Add net.ipv4.tcp_pingpong_thresh sysctl tunable, so it can be tuned for
optimal performance based on the application needs.

Add a section to netdev maintainer doc encouraging reviewers
to chime in on the mailing list.
The questions about "when is it okay to share feedback"

is "pretty much always".

with reviews a little bit to add stuff we had been recommending

Commit a12ba19269d7 ("net/mlx5: Update Kconfig parameter documentation")
adds documentation on Kconfig options for the mlx5 driver. It refers to the
config MLX5_EN_MACSEC for MACSec offloading, but the config is actually
called MLX5_MACSEC.
Fix the reference to the right config name in the documentation.

Before commit b36a5780cb44 ("ovl: modify layer parameter parsing"),
spaces and commas in lowerdir mount option value used to be escaped using
seq_show_option().
In current upstream, when lowerdir value has a space, it is not escaped
in /proc/mounts, e.g.:
none /mnt overlay rw,relatime,lowerdir=l l,upperdir=u,workdir=w 0 0
which results in broken output of the mount utility:
none on /mnt type overlay (rw,relatime,lowerdir=l)
Store the original lowerdir mount options before unescaping and show
them using the same escaping used for seq_show_option() in addition to
escaping the colon separator character.

Pull irq fixes from Thomas Gleixner:
"A set of updates for interrupt chip drivers:
- Fix the fail of the Qualcomm PDC driver on v3.2 hardware which is
caused by a control bit being moved to a different location
- Update the SM8150 device tree PDC resource so the version register
can be read
- Make the Renesas RZG2L driver correct for interrupts which are
outside of the LSB in the TSSR register by using the proper macro
for calculating the mask
- Document the Renesas RZ2GL device tree binding correctly and update
them for a few devices which faul to boot otherwise
- Use the proper accessor in the RZ2GL driver instead of blindly
dereferencing an unchecked pointer
- Make GICv3 handle the dma-non-coherent attribute correctly
- Ensure that all interrupt controller nodes on RISCV are marked as
initialized correctly
Maintainer changes:
- Add a new entry for GIC interrupt controllers and assign Marc
Zyngier as the maintainer
- Remove Marc Zyngier from the core and driver maintainer entries as
he is burried in work and short of time to handle that.
Thanks to Marc for all the great work he has done in the past couple
of years!
Also note that commit 5873d380f4c0 ("irqchip/qcom-pdc: Add support for
v3.2 HW") has a incorrect SOB chain.
The real author is Neil. His patch was posted by Dmitry once and Neil
picked it up from the list and reposted it with the bogus SOB chain.
Not a big deal, but worth to mention. I wanted to fix that up, but
then got distracted and Marc piled more changes on top. So I decided
to leave it as is instead of rebasing world"

In case an attribute is used in a subset, the type has to be currently
specified. As the attribute is already defined in the original set, this
is a redundant information in yaml file, moreover, may lead to
inconsistencies.
Example:
attribute-sets:
...
name: pin
enum-name: dpll_a_pin
attributes:
...
-
name: parent-id
type: u32
...
-
name: pin-parent-device
subset-of: pin
attributes:
-
name: parent-id
type: u32 <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
Remove the requirement from schema files to specify the "type" for
attribute subsets.

The GIC v3 specifications allow redistributors and ITSes interconnect
ports used to access memory to be wired up in a way that makes the
respective initiators/memory observers non-coherent.
Add the standard dma-noncoherent property to the GICv3 bindings to
allow firmware to describe the redistributors/ITSes components and
interconnect ports behaviour in system designs where the redistributors
and ITSes are not coherent with the CPU.
