5d4e04bf3a wifi: cfg80211: reject auth/assoc to AP with our address 
If the AP uses our own address as its MLD address or BSSID, then
clearly something's wrong. Reject such connections so we don't
try and fail later.

6d2c360b4b wifi: iwlmei: don't send nic info with invalid mac address 
In case the SAP connection is established before the interface is
added, the mac address is still not set. Don't send the nic info
SAP message in this case since it will result in sending an invalid
mac address. The nic info message will be sent with a valid mac
address when the interface is added.

057381ddac wifi: iwlwifi: pcie: avoid a warning in case prepare card failed 
In case CSME holds the NIC and SAP connection is already established,
iwl_pcie_prepare_card_hw() during iwl_pci_probe() will fail
(which is fine since CSME will release the nic later when asked with
a SAP message). In this case tring to grab nic access to read the
crf ids will fail with a warning.
Avoid the warning by only trying to read the crf ids in case prepare
card succeeded.

d166a5c977 wifi: iwlwifi: remove memory check for LMAC error address 
LMAC error table address was checked against UMAC
error table minimum address defined. Because of that,
the LMAC error table was not read, since both addresses
belong to different ranges. As addresses are updated from
FW alive message and should be correct, this check is not
needed.

Still keep the check for address 0 to avoid NULL address read.

read_mem() returns an error that's either because grab NIC access

eb2624f55a wifi: rtw89: Introduce Time Averaged SAR (TAS) feature 
Time Averaged SAR (TAS) tracks the amount of transmit power over a
period of time and adjusts the power accordingly. Two thresholds are
used to determine when to increase or reduce transmit power: Dynamic
Power Reduction (DPR) on/off. Compared to Static SAR, which has a
constant transmit power, TAS can improve the user experience or
range extension.

TAS can be enabled through BIOS, and the driver will evaluate
Realtek ACPI DSM with RTW89_ACPI_DSM_FUNC_TAS_EN to determine
whether TAS should be enabled.

There is the following note at `lib/vsprintf.c:simple_strtoull()` which
further backs this change:
| * This function has caveats. Please use kstrtoull (or kstrtoul) instead.

And here, simple_str* are explicitly deprecated [3].

This patch also removes an instance of the deprecated `strncpy` which helps [2].

429b55b441 selftests: fib_test: add a test case for IPv6 source address delete 
Add a test case for IPv6 source address delete.

As David suggested, add tests:
- Single device using src address
- Two devices with the same source address
- VRF with single device using src address
- VRF with two devices using src address

As Ido points out, in IPv6, the preferred source address is looked up in
the same VRF as the first nexthop device. This will give us similar results
to IPv4 if the route is installed in the same VRF as the nexthop device, but
not when the nexthop device is enslaved to a different VRF. So add tests:
- src address and nexthop dev in same VR
- src address and nexthop device in different VRF

The link local address delete logic is different from the global address.
It should only affect the associate device it bonds to. So add tests cases
for link local address testing.

Here is the test result:

IPv6 delete address route tests
    Single device using src address
    TEST: Prefsrc removed when src address removed on other device      [ OK ]
    Two devices with the same source address
    TEST: Prefsrc not removed when src address exist on other device    [ OK ]
    TEST: Prefsrc removed when src address removed on all devices       [ OK ]
    VRF with single device using src address
    TEST: Prefsrc removed when src address removed on other device      [ OK ]
    VRF with two devices using src address
    TEST: Prefsrc not removed when src address exist on other device    [ OK ]
    TEST: Prefsrc removed when src address removed on all devices       [ OK ]
    src address and nexthop dev in same VRF
    TEST: Prefsrc removed from VRF when source address deleted          [ OK ]
    TEST: Prefsrc in default VRF not removed                            [ OK ]
    TEST: Prefsrc not removed from VRF when source address exist        [ OK ]
    TEST: Prefsrc in default VRF removed                                [ OK ]
    src address and nexthop device in different VRF
    TEST: Prefsrc not removed from VRF when nexthop dev in diff VRF     [ OK ]
    TEST: Prefsrc not removed in default VRF                            [ OK ]
    TEST: Prefsrc removed from VRF when nexthop dev in diff VRF         [ OK ]
    TEST: Prefsrc removed in default VRF                                [ OK ]
    Table ID 0
    TEST: Prefsrc removed from default VRF when source address deleted  [ OK ]
    Link local source route

    TEST: Prefsrc removed when delete ll addr                           [ OK ]
    TEST: Prefsrc not removed when delete ll addr from other dev        [ OK ]
    TEST: Prefsrc removed even ll addr still exist on other dev         [ OK ]

b358f57f7d ipv6: do not match device when remove source route 
After deleting an IPv6 address on an interface and cleaning up the
related preferred source entries, it is important to ensure that all
routes associated with the deleted address are properly cleared. The
current implementation of rt6_remove_prefsrc() only checks the preferred
source addresses bound to the current device. However, there may be
routes that are bound to other devices but still utilize the same
preferred source address.

To address this issue, it is necessary to also delete entries that are
bound to other interfaces but share the same source address with the
current device. Failure to delete these entries would leave routes that
are bound to the deleted address unclear. Here is an example reproducer
(I have omitted unrelated routes):

+ ip link add dummy1 type dummy
+ ip link add dummy2 type dummy
+ ip link set dummy1 up
+ ip link set dummy2 up
+ ip addr add 1:2:3:4::5/64 dev dummy1
+ ip route add 7:7:7:0::1 dev dummy1 src 1:2:3:4::5
+ ip route add 7:7:7:0::2 dev dummy2 src 1:2:3:4::5
+ ip -6 route show
1:2:3:4::/64 dev dummy1 proto kernel metric 256 pref medium
7:7:7::1 dev dummy1 src 1:2:3:4::5 metric 1024 pref medium
7:7:7::2 dev dummy2 src 1:2:3:4::5 metric 1024 pref medium
+ ip addr del 1:2:3:4::5/64 dev dummy1
+ ip -6 route show
7:7:7::1 dev dummy1 metric 1024 pref medium
7:7:7::2 dev dummy2 src 1:2:3:4::5 metric 1024 pref medium

As Ido reminds, in IPv6, the preferred source address is looked up in
the same VRF as the first nexthop device, which is different with IPv4.
So, while removing the device checking, we also need to add an
ipv6_chk_addr() check to make sure the address does not exist on the other
devices of the rt nexthop device's VRF.

After fix:
+ ip addr del 1:2:3:4::5/64 dev dummy1
+ ip -6 route show
7:7:7::1 dev dummy1 metric 1024 pref medium
7:7:7::2 dev dummy2 metric 1024 pref medium
