The IEEE 802.3cg project defines two 10 Mbit/s PHYs operating over a
single pair of conductors. The 10BASE-T1L (Clause 146) is a long reach
PHY supporting full duplex point-to-point operation over 1 km of single
balanced pair of conductors. The 10BASE-T1S (Clause 147) is a short reach
PHY supporting full / half duplex point-to-point operation over 15 m of
single balanced pair of conductors, or half duplex multidrop bus
operation over 25 m of single balanced pair of conductors.
Furthermore, the IEEE 802.3cg project defines the new Physical Layer
Collision Avoidance (PLCA) Reconciliation Sublayer (Clause 148) meant to
provide improved determinism to the CSMA/CD media access method. PLCA
works in conjunction with the 10BASE-T1S PHY operating in multidrop mode.
The aforementioned PHYs are intended to cover the low-speed / low-cost
applications in industrial and automotive environment. The large number
of pins (16) required by the MII interface, which is specified by the
IEEE 802.3 in Clause 22, is one of the major cost factors that need to be
addressed to fulfil this objective.
The MAC-PHY solution integrates an IEEE Clause 4 MAC and a 10BASE-T1x PHY
exposing a low pin count Serial Peripheral Interface (SPI) to the host
microcontroller. This also enables the addition of Ethernet functionality
to existing low-end microcontrollers which do not integrate a MAC
controller.

Add a netdev_dmabuf_binding struct which represents the
dma-buf-to-netdevice binding. The netlink API will bind the dma-buf to
rx queues on the netdevice. On the binding, the dma_buf_attach
& dma_buf_map_attachment will occur. The entries in the sg_table from
mapping will be inserted into a genpool to make it ready
for allocation.
The chunks in the genpool are owned by a dmabuf_chunk_owner struct which
holds the dma-buf offset of the base of the chunk and the dma_addr of
the chunk. Both are needed to use allocations that come from this chunk.
We create a new type that represents an allocation from the genpool:
net_iov. We setup the net_iov allocation size in the
genpool to PAGE_SIZE for simplicity: to match the PAGE_SIZE normally
allocated by the page pool and given to the drivers.
The user can unbind the dmabuf from the netdevice by closing the netlink
socket that established the binding. We do this so that the binding is
automatically unbound even if the userspace process crashes.
The binding and unbinding leaves an indicator in struct netdev_rx_queue
that the given queue is bound, and the binding is actuated by resetting
the rx queue using the queue API.
The netdev_dmabuf_binding struct is refcounted, and releases its
resources only when all the refs are released.

An MPTCP firewall blackhole can be detected if the following SYN
retransmission after a fallback to "plain" TCP is accepted.
In case of blackhole, a similar technique to the one in place with TFO
is now used: MPTCP can be disabled for a certain period of time, 1h by
default. This time period will grow exponentially when more blackhole
issues get detected right after MPTCP is re-enabled and will reset to
the initial value when the blackhole issue goes away.
The blackhole period can be modified thanks to a new sysctl knob:
blackhole_timeout. Two new MIB counters help understanding what's
happening:
- 'Blackhole', incremented when a blackhole is detected.
- 'MPCapableSYNTXDisabled', incremented when an MPTCP connection
directly falls back to TCP during the blackhole period.
Because the technique is inspired by the one used by TFO, an important
part of the new code is similar to what can find in tcp_fastopen.c, with
some adaptations to the MPTCP case.

HW-Managed Flow Steering in mlx5 driver
Yevgeny Kliteynik says:
=======================
1. Overview
-----------
ConnectX devices support packet matching, modification, and redirection.
This functionality is referred as Flow Steering.
To configure a steering rule, the rule is written to the device-owned
memory. This memory is accessed and cached by the device when processing
a packet.
The first implementation of Flow Steering was done in FW, and it is
referred in the mlx5 driver as Device-Managed Flow Steering (DMFS).
Later we introduced SW-managed Flow Steering (SWS or SMFS), where the
driver is writing directly to the device's configuration memory (ICM)
through RC QP using RDMA operations (RDMA-read and RDAM-write), thus
achieving higher rates of rule insertion/deletion.
Now we introduce a new flow steering implementation: HW-Managed Flow
Steering (HWS or HMFS).
In this new approach, the driver is configuring steering rules directly
to the HW using the WQs with a special new type of WQE. This way we can
reach higher rule insertion/deletion rate with much lower CPU utilization
compared to SWS.
The key benefits of HWS as opposed to SWS:
+ HW manages the steering decision tree
- HW calculates CRC for each entry
- HW handles tree hash collisions
- HW & FW manage objects refcount
+ HW keeps cache coherency:
- HW provides tree access locking and synchronization
- HW provides notification on completion
+ Insertion rate isn’t affected by background traffic
- Dedicated HW components that handle insertion
2. Performance
--------------
Measuring Connection Tracking with simple IPv4 flows w/o NAT, we
are able to get ~5 times more flows offloaded per second using HWS.
3. Configuration
----------------
The enablement of HWS mode in eswitch manager is done using the same
devlink param that is already used for switching between FW-managed
steering and SW-managed steering modes:
# devlink dev param set pci/<PCI_ID> name flow_steering_mode cmod runtime value hmfs
4. Upstream Submission
----------------------
HWS support consists of 3 main components:
+ Steering:
- The lower layer that exposes HWS API to upper layers and implements
all the management of flow steering building blocks
+ FS-Core
- Implementation of fs_hws layer to enable fs_core to use HWS instead
of FW or SW steering
- Create HW steering action pools to utilize the ability of HWS to
share steering actions among different rules
- Add support for configuring HWS mode through devlink command,
similar to configuring SWS mode
+ Connection Tracking
- Implementation of CT support for HW steering
- Hooks up the CT ops for the new steering mode and uses the HWS API
to implement connection tracking.
Because of the large number of patches, we need to perform the submission
in several separate patch series. This series is the first submission that
lays the ground work for the next submissions, where an actual user of HWS
will be added.
5. Patches in this series
-------------------------
This patch series contains implementation of the first bullet from above.

HW-Managed Flow Steering in mlx5 driver
Yevgeny Kliteynik says:
=======================
1. Overview
-----------
ConnectX devices support packet matching, modification, and redirection.
This functionality is referred as Flow Steering.
To configure a steering rule, the rule is written to the device-owned
memory. This memory is accessed and cached by the device when processing
a packet.
The first implementation of Flow Steering was done in FW, and it is
referred in the mlx5 driver as Device-Managed Flow Steering (DMFS).
Later we introduced SW-managed Flow Steering (SWS or SMFS), where the
driver is writing directly to the device's configuration memory (ICM)
through RC QP using RDMA operations (RDMA-read and RDAM-write), thus
achieving higher rates of rule insertion/deletion.
Now we introduce a new flow steering implementation: HW-Managed Flow
Steering (HWS or HMFS).
In this new approach, the driver is configuring steering rules directly
to the HW using the WQs with a special new type of WQE. This way we can
reach higher rule insertion/deletion rate with much lower CPU utilization
compared to SWS.
The key benefits of HWS as opposed to SWS:
+ HW manages the steering decision tree
- HW calculates CRC for each entry
- HW handles tree hash collisions
- HW & FW manage objects refcount
+ HW keeps cache coherency:
- HW provides tree access locking and synchronization
- HW provides notification on completion
+ Insertion rate isn’t affected by background traffic
- Dedicated HW components that handle insertion
2. Performance
--------------
Measuring Connection Tracking with simple IPv4 flows w/o NAT, we
are able to get ~5 times more flows offloaded per second using HWS.
3. Configuration
----------------
The enablement of HWS mode in eswitch manager is done using the same
devlink param that is already used for switching between FW-managed
steering and SW-managed steering modes:
# devlink dev param set pci/<PCI_ID> name flow_steering_mode cmod runtime value hmfs
4. Upstream Submission
----------------------
HWS support consists of 3 main components:
+ Steering:
- The lower layer that exposes HWS API to upper layers and implements
all the management of flow steering building blocks
+ FS-Core
- Implementation of fs_hws layer to enable fs_core to use HWS instead
of FW or SW steering
- Create HW steering action pools to utilize the ability of HWS to
share steering actions among different rules
- Add support for configuring HWS mode through devlink command,
similar to configuring SWS mode
+ Connection Tracking
- Implementation of CT support for HW steering
- Hooks up the CT ops for the new steering mode and uses the HWS API
to implement connection tracking.
Because of the large number of patches, we need to perform the submission
in several separate patch series. This series is the first submission that
lays the ground work for the next submissions, where an actual user of HWS
will be added.
5. Patches in this series
-------------------------
This patch series contains implementation of the first bullet from above.

As Rob pointed in another mail thread [1], the binding of tja11xx PHY
is completely broken, the schema cannot catch the error in the DTS. A
compatiable string must be needed if we want to add a custom propety.
So extract known PHY IDs from the tja11xx PHY drivers and convert them
into supported compatible string list to fix the broken binding issue.

introduce a new flag SOF_TIMESTAMPING_OPT_RX_FILTER in the receive
path. User can set it with SOF_TIMESTAMPING_SOFTWARE to filter
out rx software timestamp report, especially after a process turns on
netstamp_needed_key which can time stamp every incoming skb.
Previously, we found out if an application starts first which turns on
netstamp_needed_key, then another one only passing SOF_TIMESTAMPING_SOFTWARE
could also get rx timestamp. Now we handle this case by introducing this
new flag without breaking users.
Quoting Willem to explain why we need the flag:
"why a process would want to request software timestamp reporting, but
not receive software timestamp generation. The only use I see is when
the application does request
SOF_TIMESTAMPING_SOFTWARE | SOF_TIMESTAMPING_TX_SOFTWARE."
Similarly, this new flag could also be used for hardware case where we
can set it with SOF_TIMESTAMPING_RAW_HARDWARE, then we won't receive
hardware receive timestamp.
Another thing about errqueue in this patch I have a few words to say:
In this case, we need to handle the egress path carefully, or else
reporting the tx timestamp will fail. Egress path and ingress path will
finally call sock_recv_timestamp(). We have to distinguish them.
Errqueue is a good indicator to reflect the flow direction.

In commit 6f8b12d661 ("net: napi: add hard irqs deferral feature")
napi_defer_irqs was added to net_device and napi_defer_irqs_count was
added to napi_struct, both as type int.
This value never goes below zero, so there is not reason for it to be a
signed int. Change the type for both from int to u32, and add an
overflow check to sysfs to limit the value to S32_MAX.
The limit of S32_MAX was chosen because the practical limit before this
patch was S32_MAX (anything larger was an overflow) and thus there are
no behavioral changes introduced. If the extra bit is needed in the
future, the limit can be raised.
Before this patch:
$ sudo bash -c 'echo 2147483649 > /sys/class/net/eth4/napi_defer_hard_irqs'
$ cat /sys/class/net/eth4/napi_defer_hard_irqs
-2147483647
After this patch:
$ sudo bash -c 'echo 2147483649 > /sys/class/net/eth4/napi_defer_hard_irqs'
bash: line 0: echo: write error: Numerical result out of range
Similarly, /sys/class/net/XXXXX/tx_queue_len is defined as unsigned:
include/linux/netdevice.h: unsigned int tx_queue_len;
And has an overflow check:
dev_change_tx_queue_len(..., unsigned long new_len):
if (new_len != (unsigned int)new_len)

Document what was discussed multiple times on list and various
virtual / in-person conversations. guard() being okay in functions
<= 20 LoC is a bit of my own invention. If the function is trivial
it should be fine, but feel free to disagree :)
We'll obviously revisit this guidance as time passes and we and other
subsystems get more experience.

The WL-355608-A8 is a 3.5" 640x480@60Hz RGB LCD display from an unknown
OEM used in a number of handheld gaming devices made by Anbernic.
Previously committed using the OEM serial without a vendor prefix,
however following subsequent discussion the preference is to use the
integrating device vendor and name where the OEM is unknown.
There are 4 RG35XX series devices from Anbernic based on an Allwinner
H700 SoC using this panel, with the -Plus variant introduced first.
Therefore the -Plus is used as the fallback for the subsequent -H,
-2024, and -SP devices.
Alter the filename and compatible string to reflect the convention.

This update allows listing default firewalld ruleset on Fedora 40 via
tools/net/ynl/cli.py --spec \
Documentation/netlink/specs/nftables.yaml --dump getrule
Default ruleset uses fib, reject and objref expressions which were
missing.
Other missing expressions can be added later.
Improve decoding while at it:
- add bitwise, ct and lookup attributes
- wire up the quota expression
- translate raw verdict codes to a human reable name, e.g.
'code': 4294967293 becomes 'code': 'jump'.

"Interface can't change network namespaces" is rather an attribute,
not a feature, and it can't be changed via Ethtool.
Make it a "cold" private flag instead of a netdev_feature and free
one more bit.

NETIF_F_LLTX can't be changed via Ethtool and is not a feature,
rather an attribute, very similar to IFF_NO_QUEUE (and hot).
Free one netdev_features_t bit and make it a "hot" private flag.

Make dev->priv_flags `u32` back and define bits higher than 31 as
bitfield booleans as per Jakub's suggestion. This simplifies code
which accesses these bits with no optimization loss (testb both
before/after), allows to not extend &netdev_priv_flags each time,
but also scales better as bits > 63 in the future would only add
a new u64 to the structure with no complications, comparing to
that extending ::priv_flags would require converting it to a bitmap.
Note that I picked `unsigned long :1` to not lose any potential
optimizations comparing to `bool :1` etc.

Currently, the behavior of zswap.writeback wrt. the cgroup hierarchy
seems a bit odd. Unlike zswap.max, it doesn't honor the value from parent
cgroups. This surfaced when people tried to globally disable zswap
writeback, i.e. reserve physical swap space only for hibernation [1] -
disabling zswap.writeback only for the root cgroup results in subcgroups
with zswap.writeback=1 still performing writeback.
The inconsistency became more noticeable after I introduced the
MemoryZSwapWriteback= systemd unit setting [2] for controlling the knob.
The patch assumed that the kernel would enforce the value of parent
cgroups. It could probably be workarounded from systemd's side, by going
up the slice unit tree and inheriting the value. Yet I think it's more
sensible to make it behave consistently with zswap.max and friends.
