Merge ACPICA material for v6.10. This is mostly new material included
in the 20240322 upstream ACPICA release.
- Disable -Wstringop-truncation for some ACPICA code in the kernel to
avoid a compiler warning that is not very useful (Arnd Bergmann).
- Add EINJ CXL error types to actbl1.h (Ben Cheatham).
- Add support for RAS2 table to ACPICA (Shiju Jose).
- Fix various spelling mistakes in text files and code comments in
ACPICA (Colin Ian King).
- Fix spelling and typos in ACPICA (Saket Dumbre).
- Modify ACPI_OBJECT_COMMON_HEADER (lijun).
- Add RISC-V RINTC affinity structure support to ACPICA (Haibo Xu).
- Fix CXL 3.0 structure (RDPAS) in the CEDT table (Hojin Nam).
- Add missin increment of registered GPE count to ACPICA (Daniil
Tatianin).
- Mark new ACPICA release 20240322 (Saket Dumbre).
- Add support for the AEST V2 table to ACPICA (Ruidong Tian).

Fix use after free when FW completion arrives while device is in
internal error state. Avoid calling completion handler in this case,
since the device will flush the command interface and trigger all
completions manually.

Prevent forced completion handling on an entry that has not yet been
assigned an index, causing an out of bounds access on idx = -22.
Instead of waiting indefinitely for the sem, blocking flow now waits for
index to be allocated or a sem acquisition timeout before beginning the
timer for FW completion.
Kernel log example:
mlx5_core 0000:06:00.0: wait_func_handle_exec_timeout:1128:(pid 185911): cmd[-22]: CREATE_UCTX(0xa04) No done completion

On lag disable, the bond IB device along with all of its
representors are destroyed, and then the slaves' representors get reloaded.
In case the slave IB representor load fails, the eswitch error flow
unloads all representors, including ethernet representors, where the
netdevs get detached and removed from lag bond. Such flow is inaccurate
as the lag driver is not responsible for loading/unloading ethernet
representors. Furthermore, the flow described above begins by holding
lag lock to prevent bond changes during disable flow. However, when
reaching the ethernet representors detachment from lag, the lag lock is
required again, triggering the following deadlock:

While at it, refactor the mlx5_esw_offloads_rep_load() function to have
a static helper method for its internal logic, in symmetry with the
representor unload design.

The cited patch change register devlink flow, and neglect to reflect
the changes for peer devlink set logic. Peer devlink set is
triggering a call trace if done after devl_register.[1]
Hence, align peer devlink set logic with register devlink flow.

mlx5e_suspend cleans resources only if netif_device_present() returns
true. However, mlx5e_resume changes the state of netif, via
mlx5e_nic_enable, only if reg_state == NETREG_REGISTERED.
In the below case, the above leads to NULL-ptr Oops[1] and memory
leaks:
mlx5e_probe
_mlx5e_resume
mlx5e_attach_netdev
mlx5e_nic_enable <-- netdev not reg, not calling netif_device_attach()
register_netdev <-- failed for some reason.
ERROR_FLOW:
_mlx5e_suspend <-- netif_device_present return false, resources aren't freed :(
Hence, clean resources in this case as well.

====================
net: qede: convert filter code to use extack
This series converts the filter code in the qede driver
to use NL_SET_ERR_MSG_*(extack, ...) for error handling.
Patch 1-12 converts qede_parse_flow_attr() to use extack,
along with all it's static helper functions.
qede_parse_flow_attr() is used in two places:
- qede_add_tc_flower_fltr()
- qede_flow_spec_to_rule()
In the latter call site extack is faked in the same way as
is done in mlxsw (patch 12).
While the conversion is going on, some error messages are silenced
in between patch 1-12. If wanted could squash patch 1-12 in a v3, but
I felt that it would be easier to review as 12 more trivial patches.
Patch 13 and 14, finishes up by converting qede_parse_actions(),
and ensures that extack is propagated to it, in both call contexts.

Since qede_parse_flow_attr() now does error reporting
through extack, then give it a fake extack and extract the
error message afterwards if one was set.
The extracted error message is then passed on through
DP_NOTICE(), including messages that was earlier issued
with DP_INFO().
This fake extack approach is already used by
mlxsw_env_linecard_modules_power_mode_apply() in

OVS_PACKET_CMD_EXECUTE has 3 main attributes:
- OVS_PACKET_ATTR_KEY - Packet metadata in a netlink format.
- OVS_PACKET_ATTR_PACKET - Binary packet content.
- OVS_PACKET_ATTR_ACTIONS - Actions to execute on the packet.
OVS_PACKET_ATTR_KEY is parsed first to populate sw_flow_key structure
with the metadata like conntrack state, input port, recirculation id,
etc. Then the packet itself gets parsed to populate the rest of the
keys from the packet headers.
Whenever the packet parsing code starts parsing the ICMPv6 header, it
first zeroes out fields in the key corresponding to Neighbor Discovery
information even if it is not an ND packet.
It is an 'ipv6.nd' field. However, the 'ipv6' is a union that shares
the space between 'nd' and 'ct_orig' that holds the original tuple
conntrack metadata parsed from the OVS_PACKET_ATTR_KEY.
ND packets should not normally have conntrack state, so it's fine to
share the space, but normal ICMPv6 Echo packets or maybe other types of
ICMPv6 can have the state attached and it should not be overwritten.
The issue results in all but the last 4 bytes of the destination
address being wiped from the original conntrack tuple leading to
incorrect packet matching and potentially executing wrong actions
in case this packet recirculates within the datapath or goes back
to userspace.
ND fields should not be accessed in non-ND packets, so not clearing
them should be fine. Executing memset() only for actual ND packets to
avoid the issue.
Initializing the whole thing before parsing is needed because ND packet
may not contain all the options.
The issue only affects the OVS_PACKET_CMD_EXECUTE path and doesn't
affect packets entering OVS datapath from network interfaces, because
in this case CT metadata is populated from skb after the packet is
already parsed.

Commit 1af2dface5d2 ("af_unix: Don't access successor in unix_del_edges()
during GC.") fixed use-after-free by avoid accessing edge->successor while
GC is in progress.
However, there could be a small race window where another process could
call unix_del_edges() while gc_in_progress is true and __skb_queue_purge()
is on the way.
So, we need another marker for struct scm_fp_list which indicates if the
skb is garbage-collected.
This patch adds dead flag in struct scm_fp_list and set it true before
calling __skb_queue_purge().

Real number of Transmit queues are incremented when user enables HTB
class and vice versa. Depending on SKB priority driver returns transmit
queue (Txq). Transmit queues and Send queues are one-to-one mapped.
In few scenarios, Driver is returning transmit queue value which is
greater than real number of transmit queue and Stack detects this as
error and overwrites transmit queue value.
For example
user has added two classes and real number of queues are incremented
accordingly
- tc class add dev eth1 parent 1: classid 1:1 htb
rate 100Mbit ceil 100Mbit prio 1 quantum 1024
- tc class add dev eth1 parent 1: classid 1:2 htb
rate 100Mbit ceil 200Mbit prio 7 quantum 1024
now if user deletes the class with id 1:1, driver decrements the real
number of queues
- tc class del dev eth1 classid 1:1
But for the class with id 1:2, driver is returning transmit queue
value which is higher than real number of transmit queue leading
to below error
eth1 selects TX queue x, but real number of TX queues is x
This patch solves the problem by assigning deleted class transmit
queue/send queue to active class.

Tell socat to exit after 128 bytes and pad the message.
Since the test sets -e make sure we don't set exit code
(|| true) and print the pass / fail rather then silently
moving over the test and just setting non-zero exit code
with no output indicating what failed.

Clang build brings a warning:

Erhard reports netpoll warnings from sungem:
netpoll_send_skb_on_dev(): eth0 enabled interrupts in poll (gem_start_xmit+0x0/0x398)
WARNING: CPU: 1 PID: 1 at net/core/netpoll.c:370 netpoll_send_skb+0x1fc/0x20c
gem_poll_controller() disables interrupts, which may sleep.
We can't sleep in netpoll, it has interrupts disabled completely.
Strangely, gem_poll_controller() doesn't even poll the completions,
and instead acts as if an interrupt has fired so it just schedules
NAPI and exits. None of this has been necessary for years, since
netpoll invokes NAPI directly.
