[ Upstream commit f16c40acd31901ad0ba2554b60e0e2b0c7b59cde ]
There might be some racing between BT and WiFi after scan. Since
one of the TX related register will be modified by both FW and
rtw89_set_channel() in driver, which could cause Tx fail. Reorder
the calling sequence to only notify coexistence mechanism after
rtw89_set_channel() is called, so that there are no concurrent
operations.

[ Upstream commit aad0394e7a02fe933159be79d9d4595d2ad089dd ]
The drv_priv hooked to mac80211 become as below.
(drv_priv) (instance-0)
+---------------+ +-----------+ +----------------+
| ieee80211_vif | <---> | rtw89_vif | -------> | rtw89_vif_link |
+---------------+ +-----------+ | +----------------+
|
| (instance-1)
| +----------------+
+---> | rtw89_vif_link |
+----------------+
(drv_priv) (instance-0)
+---------------+ +-----------+ +----------------+
| ieee80211_sta | <---> | rtw89_sta | -------> | rtw89_sta_link |
+---------------+ +-----------+ | +----------------+
|
| (instance-1)
| +----------------+
+---> | rtw89_sta_link |
+----------------+
The relation bewteen mac80211 link_id and our link instance is like below.
|\
(link_id) | \
0 -------- | |
1 -------- | | ------ instance-0 (link_id: X) -> work on HW band 0
2 -------- | |
... | | ------ instance-1 (link_id: Y) -> work on HW band 1
14 -------- | |
| /
|/
N.B. For cases of non-MLD connection, we set our link instance-0
active with link_id 0. So, our code flow can be compatible between
non-MLD connection and MLD connection.
Based on above, we tweak entire driver architecture first. But, we don't
dynamically enable multiple links here. That will be handled separately.
Most of the things changed here are changing flows to iterate all active
links and read bss_conf/link_sta data according to target link. And, for
cases of scan, ROC, WOW, we use instance-0 to deal with the request.
There are some things listed below, which work for now but need to extend
before multiple active links.
1. tx path
select suitable link instance among multiple active links
2. rx path
determine rx link by PPDU instead of always link instance-0
3. CAM
apply MLD pairwise key to any active links dynamically
Besides, PS code cannot easily work along with tweaking architecture. With
supporting MLO flag (currently false), we disable PS first and will fix it
by another commit in the following.

[ Upstream commit 29dd3e48b9bd88bf65a1e760126fa18d1def7b30 ]
It seems it is necessary to set WILC MAC address after operation mode,
otherwise the MAC address of the WILC MAC is reset back to what is in
nvmem. This causes a failure to associate with AP after the WILC MAC
address was overridden by userspace.
Test case:
"
ap$ cat << EOF > hostap.conf
interface=wlan0
ssid=ssid
hw_mode=g
channel=6
wpa=2
wpa_passphrase=pass
wpa_key_mgmt=WPA-PSK
EOF
ap$ hostapd -d hostap.conf
ap$ ifconfig wlan0 10.0.0.1
"
"
sta$ ifconfig wlan0 hw ether 00:11:22:33:44:55
sta$ wpa_supplicant -i wlan0 -c <(wpa_passphrase ssid pass)
sta$ ifconfig wlan0 10.0.0.2
sta$ ping 10.0.0.1 # fails without this patch
"
AP still indicates SA with original MAC address from nvmem without this patch:

[ Upstream commit a884c304e18a40e1c7a6525a9274e64c2c061c3f ]
The ice_vc_cfg_qs_msg() function is used to configure VF queues in response
to a VIRTCHNL_OP_CONFIG_VSI_QUEUES command.
The virtchnl command contains an array of queue pair data for configuring
Tx and Rx queues. This data includes a queue ID. When configuring the
queues, the driver generally uses this queue ID to determine which Tx and
Rx ring to program. However, a handful of places use the index into the
queue pair data from the VF. While most VF implementations appear to send
this data in order, it is not mandated by the virtchnl and it is not
verified that the queue pair data comes in order.
Fix the driver to consistently use the q_idx field instead of the 'i'
iterator value when accessing the rings. For the Rx case, introduce a local
ring variable to keep lines short.

[ Upstream commit 4c57ec6c4bb9979b42ae7fa7273fc2d4a361d576 ]
Currently, mem_ce and mem iomem addresses are used to calculate the
CE offset address. mem_ce is initialized with mem address, and for
targets where ce_remap is needed, mem_ce is remapped to a new address
space during AHB probe.
For targets such as WCN6750 in which CE address space is same as WCSS
address space (i.e. "ce_remap" hw_param is set to false), mem_ce and
mem iomem addresses are same. In the initial SRNG setup for such targets,
the CE offset address and hence CE register base addresses are
calculated correctly in ath11k_hal_srng_init() as both mem and mem_ce
are initialized with same iomem address.
Later, after the firmware download, mem is initialized with BAR address
received in qmi_wlanfw_device_info_resp_msg_v01 QMI message, while mem_ce
is not updated.
After initial setup success, during Subsystem Restart (SSR), as part
of reinitialization, ath11k_hal_srng_init() will be called again,
and CE offset address will be calculated incorrectly this time as mem_ce
address was not updated. Due to the incorrect CE offset address,
APPS accesses an invalid CE register address which leads to improper
behavior in firmware after SSR is triggered.
To fix the above issue, update mem_ce to mem iomem address in
ath11k_qmi_request_device_info() for targets which do not support
ce_remap feature.

During ath12k module removal, in ath12k_core_deinit(),
ath12k_mac_destroy() un-registers ah->hw from mac80211 and frees
the ah->hw as well as all the ar's in it. After this
ath12k_core_soc_destroy()-> ath12k_dp_free()-> ath12k_dp_cc_cleanup()
tries to access one of the freed ar's from pending skb.
This is because during mac destroy, driver failed to flush few
data packets, which were accessed later in ath12k_dp_cc_cleanup()
and freed, but using ar from the packet led to this use-after-free.

Commit 24de1b7b231c ("wifi: ath12k: fix flush failure in recovery
scenarios") added the change to decrement the pending packets count
in case of recovery which make sense as ah->hw as well all
ar's in it are intact during recovery, but during core deinit there
is no use in decrementing packets count or waking up the empty waitq
as the module is going to be removed also ar's from pending skb's
can't be used and the packets should just be released back.
To fix this, avoid accessing ar from skb->cb when driver is being
unregistered.

Commit 4598380f9c54 ("bonding: fix ns validation on backup slaves")
tried to resolve the issue where backup slaves couldn't be brought up when
receiving IPv6 Neighbor Solicitation (NS) messages. However, this fix only
worked for drivers that receive all multicast messages, such as the veth
interface.
For standard drivers, the NS multicast message is silently dropped because
the slave device is not a member of the NS target multicast group.
To address this, we need to make the slave device join the NS target
multicast group, ensuring it can receive these IPv6 NS messages to validate
the slave’s status properly.
There are three policies before joining the multicast group:
1. All settings must be under active-backup mode (alb and tlb do not support
arp_validate), with backup slaves and slaves supporting multicast.
2. We can add or remove multicast groups when arp_validate changes.
3. Other operations, such as enslaving, releasing, or setting NS targets,
need to be guarded by arp_validate.

The first PPS latch time needs to be calculated by the driver
(in rounded off seconds) and configured as the start time
offset for the cycle. After synchronizing two PTP clocks
running as master/slave, missing this would cause master
and slave to start immediately with some milliseconds
drift which causes the PPS signal to never synchronize with
the PTP master.

Normally, phylib won't notify changes in quick succession. However, as
a result of commit 3e43b903da04 ("net: phy: Immediately call
adjust_link if only tx_lpi_enabled changes") this is no longer true -
it is now possible that phy_link_down() and phy_link_up() will both
complete before phylink's resolver has run, which means it'll miss that
pl->phy_state.link momentarily became false.
Rename "mac_link_dropped" to be more generic "link_failed" since it will
cover more than the MAC/PCS end of the link failing, and arrange to set
this in phylink_phy_change() if we notice that the PHY reports that the
link is down.
This will ensure that we capture an EEE reconfiguration event.

The kTLS tx handling code is using a mix of get_page() and
page_ref_inc() APIs to increment the page reference. But on the release
path (mlx5e_ktls_tx_handle_resync_dump_comp()), only put_page() is used.
This is an issue when using pages from large folios: the get_page()
references are stored on the folio page while the page_ref_inc()
references are stored directly in the given page. On release the folio
page will be dereferenced too many times.
This was found while doing kTLS testing with sendfile() + ZC when the
served file was read from NFS on a kernel with NFS large folios support
(commit 49b29a573da8 ("nfs: add support for large folios")).

The referenced commits introduced a two-step process for deleting FTEs:
- Lock the FTE, delete it from hardware, set the hardware deletion function
to NULL and unlock the FTE.
- Lock the parent flow group, delete the software copy of the FTE, and
remove it from the xarray.
However, this approach encounters a race condition if a rule with the same
match value is added simultaneously. In this scenario, fs_core may set the
hardware deletion function to NULL prematurely, causing a panic during
subsequent rule deletions.
To prevent this, ensure the active flag of the FTE is checked under a lock,
which will prevent the fs_core layer from attaching a new steering rule to
an FTE that is in the process of deletion.

The number of PCI vectors allocated by the platform (which may be fewer
than requested) is currently not honored when creating the SF pool;
only the PCI MSI-X capability is considered.
As a result, when a platform allocates fewer vectors
(in non-dynamic mode) than requested, the PF and SF pools end up
with an invalid vector range.
This causes incorrect SF vector accounting, which leads to the
following call trace when an invalid IRQ vector is allocated.
This issue is resolved by ensuring that the platform's vector
limit is respected for both the SF and PF pools.

IB representors depend on ETH representors, so the IB representors
should not exist without the ETH ones. When unloading the ETH
representors, the corresponding IB representors should be also
unloaded.
The commit 8d159eb2117b ("RDMA/mlx5: Use IB set_netdev and get_netdev functions")
introduced the use of the ib_device_set_netdev API in IB
repsresentors. ib_device_set_netdev() increments the refcount of
the representor's netdev when loading an IB representor and
decrements it when unloading.
Without the unloading of the IB representor, the refcount of the
representor's netdev remains greater than 0, preventing it from
being unregistered.
The patch uncovered an underlying bug where the eth representor is
unloaded, without unloading the IB representor.
This issue happened when using multiport E-switch and rebooting,
causing the shutdown to hang when unloading the ETH representor
because the refcount of the representor's netdevice was greater than 0.
Call trace:
unregister_netdevice: waiting for eth3 to become free. Usage count = 2

The ionic_setup_one() creates a debugfs entry for ionic upon
successful execution. However, the ionic_probe() does not
release the dentry before returning, resulting in a memory
leak.
To fix this bug, we add the ionic_debugfs_del_dev() to release
the resources in a timely manner before returning.

The binding emac_rockchip.txt is converted to YAML.
Changed against the original binding is an added MDIO subnode.
This make the driver failed to find the PHY, and given the 'mdio
has invalid PHY address' it is probably looking in the wrong node.
Fix emac_mdio.c so that it can handle both old and new
device trees.

RSS configuration should be updated with queue number. In particular, it
should be updated when (1) rss enabled and (2) default rss configuration
is used without user modification.
During rss command processing, device updates queue_pairs using
rss.max_tx_vq. That is, the device updates queue_pairs together with
rss, so we can skip the sperate queue_pairs update
(VIRTIO_NET_CTRL_MQ_VQ_PAIRS_SET below) and return directly.
Also remove the `vi->has_rss ?` check when setting vi->rss.max_tx_vq,
because this is not used in the other hash_report case.

During virtnet_probe, default rss configuration is initialized, but was
not committed to the device. This patch fix this by sending rss command
after device ready in virtnet_probe. Otherwise, the actual rss
configuration used by device can be different with that read by user
from driver, which may confuse the user.
If the command committing fails, driver rss will be disabled.
