[ Upstream commit 74382aebc9035470ec4c789bdb0d09d8c14f261e ]
Adding/updating VSI list rule, as well as allocating/freeing VSI list
resource are called several times with type ICE_SW_LKUP_LAST, which fails
because ice_update_vsi_list_rule() and ice_aq_alloc_free_vsi_list()
consider it invalid. Allow calling these functions with ICE_SW_LKUP_LAST.
This fixes at least one issue in switchdev mode, where the same rule with
different action cannot be added, e.g.:
tc filter add dev $PF1 ingress protocol arp prio 0 flower skip_sw \
dst_mac ff:ff:ff:ff:ff:ff action mirred egress redirect dev $VF1_PR
tc filter add dev $PF1 ingress protocol arp prio 0 flower skip_sw \
dst_mac ff:ff:ff:ff:ff:ff action mirred egress redirect dev $VF2_PR

The XDP program can't correctly handle partially checksummed
packets, but works fine with fully checksummed packets. If the
device has already validated fully checksummed packets, then
the driver doesn't need to re-validate them, saving CPU resources.
Additionally, the driver does not drop all partially checksummed
packets when VIRTIO_NET_F_GUEST_CSUM is not negotiated. This is
not a bug, as the driver has always done this.

[ Upstream commit 604141c036e1b636e2a71cf6e1aa09d1e45f40c2 ]
In virtio spec 0.95, VIRTIO_NET_F_GUEST_CSUM was designed to handle
partially checksummed packets, and the validation of fully checksummed
packets by the device is independent of VIRTIO_NET_F_GUEST_CSUM
negotiation. However, the specification erroneously stated:
"If VIRTIO_NET_F_GUEST_CSUM is not negotiated, the device MUST set flags
to zero and SHOULD supply a fully checksummed packet to the driver."
This statement is inaccurate because even without VIRTIO_NET_F_GUEST_CSUM
negotiation, the device can still set the VIRTIO_NET_HDR_F_DATA_VALID flag.
Essentially, the device can facilitate the validation of these packets'
checksums - a process known as RX checksum offloading - removing the need
for the driver to do so.
This scenario is currently not implemented in the driver and requires
correction. The necessary specification correction[1] has been made and
approved in the virtio TC vote.

[ Upstream commit 88c67aeb14070bab61d3dd8be96c8b42ebcaf53a ]
zones_ht is a global hashtable for flow_table with zone as key. However,
it does not consider netns when getting a flow_table from zones_ht in
tcf_ct_init(), and it means an act_ct action in netns A may get a
flow_table that belongs to netns B if it has the same zone value.
In Shuang's test with the TOPO:
tcf2_c <---> tcf2_sw1 <---> tcf2_sw2 <---> tcf2_s
tcf2_sw1 and tcf2_sw2 saw the same flow and used the same flow table,
which caused their ct entries entering unexpected states and the
TCP connection not able to end normally.
This patch fixes the issue simply by adding netns into the key of
tcf_ct_flow_table so that an act_ct action gets a flow_table that
belongs to its own netns in tcf_ct_init().
Note that for easy coding we don't use tcf_ct_flow_table.nf_ft.net,
as the ct_ft is initialized after inserting it to the hashtable in
tcf_ct_flow_table_get() and also it requires to implement several
functions in rhashtable_params including hashfn, obj_hashfn and
obj_cmpfn.

[ Upstream commit 4b55e86736d5b492cf689125da2600f59c7d2c39 ]
Instead of relying only on the idrinfo->lock mutex for
bind/alloc logic, rely on a combination of rcu + mutex + atomics
to better scale the case where multiple rtnl-less filters are
binding to the same action object.
Action binding happens when an action index is specified explicitly and
an action exists which such index exists. Example:
tc actions add action drop index 1
tc filter add ... matchall action drop index 1
tc filter add ... matchall action drop index 1
tc filter add ... matchall action drop index 1
tc filter ls ...
filter protocol all pref 49150 matchall chain 0 filter protocol all pref 49150 matchall chain 0 handle 0x1
not_in_hw
action order 1: gact action drop
random type none pass val 0
index 1 ref 4 bind 3
filter protocol all pref 49151 matchall chain 0 filter protocol all pref 49151 matchall chain 0 handle 0x1
not_in_hw
action order 1: gact action drop
random type none pass val 0
index 1 ref 4 bind 3
filter protocol all pref 49152 matchall chain 0 filter protocol all pref 49152 matchall chain 0 handle 0x1
not_in_hw
action order 1: gact action drop
random type none pass val 0
index 1 ref 4 bind 3
When no index is specified, as before, grab the mutex and allocate
in the idr the next available id. In this version, as opposed to before,
it's simplified to store the -EBUSY pointer instead of the previous
alloc + replace combination.
When an index is specified, rely on rcu to find if there's an object in
such index. If there's none, fallback to the above, serializing on the
mutex and reserving the specified id. If there's one, it can be an -EBUSY
pointer, in which case we just try again until it's an action, or an action.
Given the rcu guarantees, the action found could be dead and therefore
we need to bump the refcount if it's not 0, handling the case it's
in fact 0.
As bind and the action refcount are already atomics, these increments can
happen without the mutex protection while many tcf_idr_check_alloc race
to bind to the same action instance.
In case binding encounters a parallel delete or add, it will return
-EAGAIN in order to try again. Both filter and action apis already
have the retry machinery in-place. In case it's an unlocked filter it
retries under the rtnl lock.

syzkaller builds (CONFIG_DEBUG_NET=y) frequently trigger a debug
hint in pskb_may_pull.
We'd like to retain this debug check because it might hint at integer
overflows and other issues (kernel code should pull headers, not huge
value).
In bpf case, this splat isn't interesting at all: such (nonsensical)
bpf programs are typically generated by a fuzzer anyway.
Do what Eric suggested and suppress such warning.
For CONFIG_DEBUG_NET=n we don't need the extra check because
pskb_may_pull will do the right thing: return an error without the
WARN() backtrace.

A bug in https://bugzilla.kernel.org/show_bug.cgi?id=218906 describes
that irdma would break and report hardware initialization failed after
suspend/resume with Intel E810 NIC (tested on 6.9.0-rc5).
The problem is caused due to the collision between the irq numbers
requested in irdma and the irq numbers requested in other drivers
after suspend/resume.
The irq numbers used by irdma are derived from ice's ice_pf->msix_entries
which stores mappings between MSI-X index and Linux interrupt number.
It's supposed to be cleaned up when suspend and rebuilt in resume but
it's not, causing irdma using the old irq numbers stored in the old
ice_pf->msix_entries to request_irq() when resume. And eventually
collide with other drivers.
This patch fixes this problem. On suspend, we call ice_deinit_rdma() to
clean up the ice_pf->msix_entries (and free the MSI-X vectors used by
irdma if we've dynamically allocated them). On resume, we call
ice_init_rdma() to rebuild the ice_pf->msix_entries (and allocate the
MSI-X vectors if we would like to dynamically allocate them).

On runtime resume, pci_dev_wait() is called:
pci_pm_runtime_resume()
pci_pm_bridge_power_up_actions()
pci_bridge_wait_for_secondary_bus()
pci_dev_wait()
While a device is runtime suspended along with its PCI hierarchy, the
device could get disconnected. In such case, the link will not come up no
matter how long pci_dev_wait() waits for it.
Besides the above mentioned case, there could be other ways to get the
device disconnected while pci_dev_wait() is waiting for the link to come
up.
Make pci_dev_wait() exit if the device is already disconnected to avoid
unnecessary delay.
The use cases of pci_dev_wait() boil down to two:
1. Waiting for the device after reset
2. pci_bridge_wait_for_secondary_bus()
The callers in both cases seem to benefit from propagating the
disconnection as error even if device disconnection would be more
analoguous to the case where there is no device in the first place which
return 0 from pci_dev_wait(). In the case 2, it results in unnecessary
marking of the devices disconnected again but that is just harmless extra
work.
Also make sure compiler does not become too clever with dev->error_state
and use READ_ONCE() to force a fetch for the up-to-date value.

It is reported that _DSM evaluation fails in ucsi_acpi_dsm() on Lenovo
IdeaPad Pro 5 due to a missing address space handler for the EC address
space:
ACPI Error: No handler for Region [ECSI] (000000007b8176ee) [EmbeddedControl] (20230628/evregion-130)
This happens because if there is no ECDT, the EC driver only registers
the EC address space handler for operation regions defined in the EC
device scope of the ACPI namespace while the operation region being
accessed by the _DSM in question is located beyond that scope.
To address this, modify the ACPI EC driver to install the EC address
space handler at the root of the ACPI namespace for the first EC that
can be found regardless of whether or not an ECDT is present.
Note that this change is consistent with some examples in the ACPI
specification in which EC operation regions located outside the EC
device scope are used (for example, see Section 9.17.15 in ACPI 6.5),
so the current behavior of the EC driver is arguably questionable.

The standard PCIe configuration read-write interface is used to
access the configuration space of the peripheral PCIe devices
of the mips processor after the PCIe link surprise down, it can
generate kernel panic caused by "Data bus error". So it is
necessary to add PCIe link status check for system protection.
When the PCIe link is down or in training, assigning a value
of 0 to the configuration address can prevent read-write behavior
to the configuration space of peripheral PCIe devices, thereby
preventing kernel panic.

Hewlett-Packard HP Pavilion 17 Notebook PC/1972 is an Intel Ivy Bridge

with the following sequence:
ACPI Error: Aborting method \AMD3._ON due to previous error (AE_AML_LOOP_TIMEOUT) (20230628/psparse-529)

radeon 0000:01:00.0: Unable to change power state from D3cold to D0, device inaccessible
The issue is that the Root Port the dGPU is connected to can't handle the
transition from D3cold to D0 so the dGPU can't properly exit runtime PM.
The existing logic in pci_bridge_d3_possible() checks for systems that are
newer than 2015 to decide that D3 is safe. This would nominally work for
an Ivy Bridge system (which was discontinued in 2015), but this system
appears to have continued to receive BIOS updates until 2017 and so this
existing logic doesn't appropriately capture it.
Add the system to bridge_d3_blacklist to prevent D3cold from being used.
