c23fb2c822 ipv6: addrlabel: fix infoleak when sending struct ifaddrlblmsg to network
When copying a `struct ifaddrlblmsg` to the network, __ifal_reserved

fd23df72f2 net: ethernet: ti: am65-cpsw: Add suspend/resume support
Add PM handlers for System suspend/resume.

As DMA driver doesn't yet support suspend/resume we free up
the DMA channels at suspend and acquire and initialize them
at resume.

Move the init/free dma calls to ndo_open/close() hooks so
it is symmetric and easier to invoke from suspend/resume handler.

As CPTS looses contect during suspend/resume, invoke the
necessary CPTS suspend/resume helpers.

53eb64c88f platform/x86: p2sb: Don't fail if unknown CPU is found
We have accessing P2SB from a very few places for quite known hardware.

When a new SoC appears in intel-family.h it's not obvious that it needs
to be added to p2sb.c as well. Instead, provide default BDF and refactor
p2sb_get_devfn() to always succeed. If in the future we would need to
exclude something, we may add a list of unsupported IDs.

Without this change the iTCO on Intel Comet Lake SoCs became unavailable:

1598bfa8e1 platform/x86: hp_wmi: Fix rfkill causing soft blocked wifi
After upgrading BIOS to U82 01.02.01 Rev.A, the console is flooded
strange char "^@" which printed out every second and makes login
nearly impossible. Also the below messages were shown both in console
and journal/dmesg every second:

usb 1-3: Device not responding to setup address.
usb 1-3: device not accepting address 4, error -71
usb 1-3: device descriptor read/all, error -71
usb usb1-port3: unable to enumerate USB device

Wifi is soft blocked by checking rfkill. When unblocked manually,
after few seconds it would be soft blocked again. So I was suspecting
something triggered rfkill to soft block wifi.  At the end it was
fixed by removing hp_wmi module.

The root cause is the way hp-wmi driver handles command 1B on
post-2009 BIOS.  In pre-2009 BIOS, command 1Bh return 0x4 to indicate
that BIOS no longer controls the power for the wireless devices.

454d61a56d ACPI: video: Make acpi_video_backlight_use_native() always return true
Testing has shown that there are quite a few laptop models which rely
on native backlight control and which do not support ACPI video bus
backlight control, causing __acpi_video_get_backlight_type() to return
vendor. Known Windows laptop models affected by this are:

Acer Aspire 1640
HP Compaq nc6120
IBM ThinkPad X40
System76 Starling Star1

and the following MacBook models are affected too:

Apple MacBook 2.1
Apple MacBook 4.1
Apple MacBook Pro 7.1

the list of affected Windows laptop models is likely just the top of
the iceberg. So for now lets undo the change to not register native
backlight class devices when __acpi_video_get_backlight_type() != native.

Since as part of the backlight-detect refactor the detection code now
relies on the GPU drivers calling acpi_video_backlight_use_native() to
learn that native backlight support is available we cannot just remove
the acpi_video_backlight_use_native() calls from the GPU drivers.

Instead modify acpi_video_backlight_use_native() to always return true
for now. This is meant as a temporary work-around, which will be removed
again when the heuristics from __acpi_video_get_backlight_type() have
been improved so that they will return native on affected models.

0c175da7b0 tcp: prohibit TCP_REPAIR_OPTIONS if data was already sent
If setsockopt with option name of TCP_REPAIR_OPTIONS and opt_code
of TCPOPT_SACK_PERM is called to enable sack after data is sent
and dupacks are received , it will trigger a warning in function
tcp_verify_left_out() as follows:

============================================
WARNING: CPU: 8 PID: 0 at net/ipv4/tcp_input.c:2132
tcp_timeout_mark_lost+0x154/0x160
tcp_enter_loss+0x2b/0x290

run_timer_softirq+0x43/0xb0
__do_softirq+0xfd/0x373
__irq_exit_rcu+0xf6/0x140

The warning is caused in the following steps:
1. a socket named socketA is created
2. socketA enters repair mode without build a connection
3. socketA calls connect() and its state is changed to TCP_ESTABLISHED
   directly
4. socketA leaves repair mode
5. socketA calls sendmsg() to send data, packets_out and sack_outs(dup
   ack receives) increase
6. socketA enters repair mode again
7. socketA calls setsockopt with TCPOPT_SACK_PERM to enable sack
8. retransmit timer expires, it calls tcp_timeout_mark_lost(), lost_out
   increases
9. sack_outs + lost_out > packets_out triggers since lost_out and
   sack_outs increase repeatly

In function tcp_timeout_mark_lost(), tp->sacked_out will be cleared if
Step7 not happen and the warning will not be triggered. As suggested by
Denis and Eric, TCP_REPAIR_OPTIONS should be prohibited if data was
already sent.

socket-tcp tests in CRIU has been tested as follows:
$ sudo ./test/zdtm.py run -t zdtm/static/socket-tcp*  --keep-going \
       --ignore-taint

socket-tcp* represent all socket-tcp tests in test/zdtm/static/.

Simplify the code logic of handling the quirk of FEC_QUIRK_HAS_RACC.

This patch handles the logic in one place to make the logic simple
and clean. The patch optimizes the fec_enet_xdp_get_tx_queue function
according to Paolo Abeni's comments, and it also exludes the SoCs that
require to do frame swap from XDP support.

13265568a8 net: hinic: Add control command support for VF PMD driver in DPDK
HINIC has a mailbox for PF-VF communication and the VF driver
could send port control command to PF driver via mailbox.

The control command only can be set to register in PF,
so add support in PF driver for VF PMD driver control
command when VF PMD driver work with linux PF driver.

Then, no need to add handlers to nic_vf_cmd_msg_handler[],
because the host driver just forwards it to the firmware.
Actually the firmware works on a coprocessor MGMT_CPU(inside the NIC)
which will recv and deal with these commands.

Pull cxl fixes from Dan Williams:
 "Several fixes for CXL region creation crashes, leaks and failures.

  This is mainly fallout from the original implementation of dynamic CXL
  region creation (instantiate new physical memory pools) that arrived
  in v6.0-rc1.

  Given the theme of "failures in the presence of pass-through decoders"
  this also includes new regression test infrastructure for that case.

  Summary:

   - Fix region creation crash with pass-through decoders

   - Fix region creation crash when no decoder allocation fails

   - Fix region creation crash when scanning regions to enforce the
     increasing physical address order constraint that CXL mandates

   - Fix a memory leak for cxl_pmem_region objects, track 1:N instead of
     1:1 memory-device-to-region associations.

   - Fix a memory leak for cxl_region objects when regions with active
     targets are deleted

   - Fix assignment of NUMA nodes to CXL regions by CFMWS (CXL Window)
     emulated proximity domains.

   - Fix region creation failure for switch attached devices downstream
     of a single-port host-bridge

   - Fix false positive memory leak of cxl_region objects by recycling
     recently used region ids rather than freeing them

   - Add regression test infrastructure for a pass-through decoder

328687151b mm/slab_common: Restore passing "caller" for tracing
The "caller" argument was accidentally being ignored in a few places
that were recently refactored. Restore these "caller" arguments, instead
of _RET_IP_.
