If the base-time for taprio is in the past, start the schedule at the time
of the form "base_time + N*cycle_time" where N is the smallest possible
integer such that the above time is in the future.

This pattern of strncpy with some pointer arithmetic setting fixed-sized
intervals with string literal data is a bit weird so let's use
ethtool_puts() as this has more obvious behavior and is less-error
prone.
Nicely, we also get to drop a usage of the now deprecated strncpy() [1].

This patch adds support to per-packet Tx hardware timestamp request to
AF_XDP zero-copy packet via XDP Tx metadata framework. Please note that
user needs to enable Tx HW timestamp capability via igc_ioctl() with
SIOCSHWTSTAMP cmd before sending xsk Tx hardware timestamp request.
Same as implementation in RX timestamp XDP hints kfunc metadata, Timer 0
(adjustable clock) is used in xsk Tx hardware timestamp. i225/i226 have
four sets of timestamping registers. *skb and *xsk_tx_buffer pointers
are used to indicate whether the timestamping register is already occupied.
Furthermore, a boolean variable named xsk_pending_ts is used to hold the
transmit completion until the tx hardware timestamp is ready. This is
because, for i225/i226, the timestamp notification event comes some time
after the transmit completion event. The driver will retrigger hardware irq
to clean the packet after retrieve the tx hardware timestamp.
Besides, xsk_meta is added into struct igc_tx_timestamp_request as a hook
to the metadata location of the transmit packet. When the Tx timestamp
interrupt is fired, the interrupt handler will copy the value of Tx hwts
into metadata location via xsk_tx_metadata_complete().
This patch is tested with tools/testing/selftests/bpf/xdp_hw_metadata
on Intel ADL-S platform. Below are the test steps and results.
Test Step 1: Run xdp_hw_metadata app
./xdp_hw_metadata <iface> > /dev/shm/result.log
Test Step 2: Enable Tx hardware timestamp
hwstamp_ctl -i <iface> -t 1 -r 1
Test Step 3: Run ptp4l and phc2sys for time synchronization
Test Step 4: Generate UDP packets with 1ms interval for 10s
trafgen --dev <iface> '{eth(da=<addr>), udp(dp=9091)}' -t 1ms -n 10000
Test Step 5: Rerun Step 1-3 with 10s iperf3 as background traffic
Test Step 6: Rerun Step 1-4 with 10s iperf3 as background traffic
Based on iperf3 results below, the impact of holding tx completion to
throughput is not observable.

Usage:
kconfig options:
- CONFIG_MEM_ALLOC_PROFILING
- CONFIG_MEM_ALLOC_PROFILING_ENABLED_BY_DEFAULT
- CONFIG_MEM_ALLOC_PROFILING_DEBUG
adds warnings for allocations that weren't accounted because of a
missing annotation
sysctl:
/proc/sys/vm/mem_profiling
Runtime info:
/proc/allocinfo
Notes:
[1]: Overhead
To measure the overhead we are comparing the following configurations:
(1) Baseline with CONFIG_MEMCG_KMEM=n
(2) Disabled by default (CONFIG_MEM_ALLOC_PROFILING=y &&
CONFIG_MEM_ALLOC_PROFILING_BY_DEFAULT=n)
(3) Enabled by default (CONFIG_MEM_ALLOC_PROFILING=y &&
CONFIG_MEM_ALLOC_PROFILING_BY_DEFAULT=y)
(4) Enabled at runtime (CONFIG_MEM_ALLOC_PROFILING=y &&
CONFIG_MEM_ALLOC_PROFILING_BY_DEFAULT=n && /proc/sys/vm/mem_profiling=1)
(5) Baseline with CONFIG_MEMCG_KMEM=y && allocating with __GFP_ACCOUNT
(6) Disabled by default (CONFIG_MEM_ALLOC_PROFILING=y &&
CONFIG_MEM_ALLOC_PROFILING_BY_DEFAULT=n) && CONFIG_MEMCG_KMEM=y
(7) Enabled by default (CONFIG_MEM_ALLOC_PROFILING=y &&
CONFIG_MEM_ALLOC_PROFILING_BY_DEFAULT=y) && CONFIG_MEMCG_KMEM=y
Performance overhead:
To evaluate performance we implemented an in-kernel test executing
multiple get_free_page/free_page and kmalloc/kfree calls with allocation
sizes growing from 8 to 240 bytes with CPU frequency set to max and CPU
affinity set to a specific CPU to minimize the noise. Below are results
from running the test on Ubuntu 22.04.2 LTS with 6.8.0-rc1 kernel on
56 core Intel Xeon:
kmalloc pgalloc
(1 baseline) 6.764s 16.902s
(2 default disabled) 6.793s (+0.43%) 17.007s (+0.62%)
(3 default enabled) 7.197s (+6.40%) 23.666s (+40.02%)
(4 runtime enabled) 7.405s (+9.48%) 23.901s (+41.41%)
(5 memcg) 13.388s (+97.94%) 48.460s (+186.71%)
(6 def disabled+memcg) 13.332s (+97.10%) 48.105s (+184.61%)

====================
net: intel: start The Great Code Dedup + Page Pool for iavf
Alexander Lobakin says:
Here's a two-shot: introduce {,Intel} Ethernet common library (libeth and
libie) and switch iavf to Page Pool. Details are in the commit messages;
here's a summary:
Not a secret there's a ton of code duplication between two and more Intel
ethernet modules. Before introducing new changes, which would need to be
copied over again, start decoupling the already existing duplicate
functionality into a new module, which will be shared between several
Intel Ethernet drivers. The first name that came to my mind was
"libie" -- "Intel Ethernet common library". Also this sounds like
"lovelie" (-> one word, no "lib I E" pls) and can be expanded as
"lib Internet Explorer" :P
The "generic", pure-software part is placed separately, so that it can be
easily reused in any driver by any vendor without linking to the Intel
pre-200G guts. In a few words, it's something any modern driver does the
same way, but nobody moved it level up (yet).
The series is only the beginning. From now on, adding every new feature
or doing any good driver refactoring will remove much more lines than add
for quite some time. There's a basic roadmap with some deduplications
planned already, not speaking of that touching every line now asks:
"can I share this?". The final destination is very ambitious: have only
one unified driver for at least i40e, ice, iavf, and idpf with a struct
ops for each generation. That's never gonna happen, right? But you still
can at least try.
PP conversion for iavf lands within the same series as these two are tied
closely. libie will support Page Pool model only, so that a driver can't
use much of the lib until it's converted. iavf is only the example, the
rest will eventually be converted soon on a per-driver basis. That is
when it gets really interesting. Stay tech.
* '40GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
MAINTAINERS: add entry for libeth and libie
iavf: switch to Page Pool
iavf: pack iavf_ring more efficiently
libeth: add Rx buffer management
page_pool: add DMA-sync-for-CPU inline helper
page_pool: constify some read-only function arguments
slab: introduce kvmalloc_array_node() and kvcalloc_node()
iavf: drop page splitting and recycling
iavf: kill "legacy-rx" for good
net: intel: introduce {, Intel} Ethernet common library

The fragment lookup should only be performed, when
at least one of the fragment flags are set.
This change was deliberately not included in commit
68aba00483c7 ("net: sparx5: flower: fix fragment flags handling")
as it's only needed for future proffing the code, since
"mask" is currently only set in conjunction with the
fragment flags.
(The 3rd flag FLOW_DIS_ENCAPSULATION is only used with "key")

Embedding net_device into structures prohibits the usage of flexible
arrays in the net_device structure. For more details, see the discussion
at [1].
Un-embed the net_device from the private struct by converting it
into a pointer. Then use the leverage the new alloc_netdev_dummy()
helper to allocate and initialize dummy devices.

We try to access count + 1 byte from userspace with memdup_user(buffer,
count + 1). However, the userspace only provides buffer of count bytes and
only these count bytes are verified to be okay to access. To ensure the
copied buffer is NUL terminated, we use memdup_user_nul instead.

Currently, we allocate a nbytes-sized kernel buffer and copy nbytes from
userspace to that buffer. Later, we use sscanf on this buffer but we don't
ensure that the string is terminated inside the buffer, this can lead to
OOB read when using sscanf. Fix this issue by using memdup_user_nul
instead of memdup_user.

Someone complains the message appears continuously. This occurs
because the device is woken from UPS mode, and the driver re-loads
the firmware.
When the device enters runtime suspend and cable is unplugged, the
device would enter UPS mode. If the runtime resume occurs, and the
device is woken from UPS mode, the driver has to re-load the firmware
and causes the message. If someone wakes the device continuously, the
message would be shown continuously, too. Use dev_dbg to avoid it.
Note that, the function could be called before register_netdev(), so I
don't use netif_info() or netif_dbg().

Enhance the quirk for Fibrestore 2.5G copper SFP module. The original
commit e27aca3760c0 ("net: sfp: add quirk for FS's 2.5G copper SFP")
introducing the quirk says that the PHY is inaccessible, but that is
not true.
The module uses Rollball protocol to talk to the PHY, and needs a 4
second wait before probing it, same as FS 10G module.
The PHY inside the module is Realtek RTL8221B-VB-CG PHY. The realtek
driver recently gained support to set it up via clause 45 accesses.

====================
wireless-next patches for v6.10
The second "new features" pull request for v6.10 with changes both in
stack and in drivers. This time the pull request is rather small and
nothing special standing out except maybe that we have several
kernel-doc fixes. Great to see that we are getting warning free
wireless code (until new warnings are added).
Major changes:
rtl8xxxu:
* enable Management Frame Protection (MFP) support
rtw88:
* disable unsupported interface type of mesh point for all chips, and only
support station mode for SDIO chips.
* tag 'wireless-next-2024-04-24' of git://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-next: (63 commits)
