b39d501645 arm64: dts: ls208xa: use a pseudo-bus to constrain usb dma size
Wrap the usb controllers in an intermediate simple-bus and use it to
constrain the dma address size of these usb controllers to the 40b
that they generate toward the interconnect. This is required because
the SoC uses 48b address sizes and this mismatch would lead to smmu
context faults [1] because the usb generates 40b addresses while the
smmu page tables are populated with 48b wide addresses.

e18f3dc2be tools: ynl-gen: lift type requirement for attribute subsets
In case an attribute is used in a subset, the type has to be currently
specified. As the attribute is already defined in the original set, this
is a redundant information in yaml file, moreover, may lead to
inconsistencies.

Example:
attribute-sets:
    ...
    name: pin
    enum-name: dpll_a_pin
    attributes:
      ...
      -
        name: parent-id
        type: u32
      ...
  -
    name: pin-parent-device
    subset-of: pin
    attributes:
      -
        name: parent-id
        type: u32             <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<

c042353955 cavium/liquidio: replace deprecated strncpy with strscpy
`strncpy` is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.

We expect `app_name` to be NUL-terminated:
	dev_info(&oct->pci_dev->dev,
		 "Running %s (%llu Hz)\n",
		 app_name, CVM_CAST64(cs->corefreq));
... and it seems NUL-padding is not required, let's opt for strscpy().

For `oct->boardinfo.name/serial_number` let's opt for strscpy() as well
since it is expected to be NUL-terminated and does not require
NUL-padding as `oct` is zero-initialized in octeon_device.c +707:
|       buf = vzalloc(size);
|       if (!buf)
|       	return NULL;
|
|       oct = (struct octeon_device *)buf;

092b0be650 net: liquidio: replace deprecated strncpy with strscpy_pad
`strncpy` is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.

We know `fw_type` must be NUL-terminated based on use here:
|       static bool fw_type_is_auto(void)
|       {
|       	return strncmp(fw_type, LIO_FW_NAME_TYPE_AUTO,
|       		       sizeof(LIO_FW_NAME_TYPE_AUTO)) == 0;
|       }
...and here
|       module_param_string(fw_type, fw_type, sizeof(fw_type), 0444);

Let's opt to NUL-pad the destination buffer as well so that we maintain
the same exact behavior that `strncpy` provided here.

A suitable replacement is `strscpy_pad` due to the fact that it
guarantees both NUL-termination and NUL-padding on the destination
buffer.

A suitable replacement is strscpy() [2] due to the fact that it

bc8e03e9f9 dt-bindings: arm: Add SolidRun LX2162A SoM & Clearfog Board
SolidRun now have 2 product lines around NXP Layerscape SoC:
- LX2160A COM Express 7
- LX2162A System on Module

LX2162 is a smaller package and reduced feature set to LX2160A;
LX2162 SoM is also a smaller form factor and reduced feature set to CEX.

Since both product lines are physically incompatible,
the existing group "SolidRun LX2160A based Boards" has been renamed to
include "CEX" in its name, meaning products based on LX2160A COM Express
Module, following this pattern:

e66413faa5 scsi: ufs: core: Remove dev cmd clock scaling busy
If a dev command times out, clk_scaling.active_reqs is not decreased which
causes abnormal clock scaling.

It is complicated to handle different dev command timeout cases in both
legacy mode and MCQ mode. Besides, dev cmds are rarely used and the busy
time is short.

Remove clock scaling busy window for dev cmds like we do for UIC or TM cmds
which don't update busy window either.

45e833f0e5 scsi: message: fusion: Replace deprecated strncpy() with strscpy()
strncpy() is deprecated for use on NUL-terminated destination strings [1]
and as such we should prefer more robust and less ambiguous string
interfaces.

The only caller of mptsas_exp_repmanufacture_info() is
mptsas_probe_one_phy() which can allocate rphy in either
sas_end_device_alloc() or sas_expander_alloc(). Both of which
zero-allocate:

|       rdev = kzalloc(sizeof(*rdev), GFP_KERNEL);

... this is supplied to mptsas_exp_repmanufacture_info() as edev meaning
that no future NUL-padding of edev members is needed.

Considering the above, a suitable replacement is strscpy() [2] due to the
fact that it guarantees NUL-termination on the destination buffer without
unnecessarily NUL-padding.

Also use the more idiomatic strscpy() pattern of (dest, src, sizeof(dest)).

4280a0a701 scsi: message: fusion: Replace deprecated strncpy() with strscpy_pad()
strncpy() is deprecated for use on NUL-terminated destination strings [1]
and as such we should prefer more robust and less ambiguous string
interfaces.

Since all these structs are copied out to userspace let's keep them
NUL-padded by using strscpy_pad() which guarantees NUL-termination of the
destination buffer while also providing the NUL-padding behavior that
strncpy() has.

Let's also opt to use the more idiomatic strscpy() usage of: 'dest, src,
sizeof(dest)' in cases where the compiler can determine the size of the
destination buffer. Do this for all cases of strscpy...() in this file.

To be abundantly sure we don't leak stack data out to user space let's also
change a strscpy() to strscpy_pad(). This strscpy() was introduced in
commit dbe37c71d1 ("scsi: message: fusion: Replace all non-returning
strlcpy() with strscpy()")

Note that since we are creating these structs with a copy_from_user() and
modifying fields and then copying back out to the user it is probably OK
not to explicitly NUL-pad everything as any data leak is probably just data
from the user themselves. If this is too eager, let's opt for strscpy()
which is still in the spirit of removing deprecated strncpy() usage
treewide.

bf328e22e4 KVM: x86: Don't sync user-written TSC against startup values
The legacy API for setting the TSC is fundamentally broken, and only
allows userspace to set a TSC "now", without any way to account for
time lost between the calculation of the value, and the kernel eventually
handling the ioctl.

To work around this, KVM has a hack which, if a TSC is set with a value
which is within a second's worth of the last TSC "written" to any vCPU in
the VM, assumes that userspace actually intended the two TSC values to be
in sync and adjusts the newly-written TSC value accordingly.

Thus, when a VMM restores a guest after suspend or migration using the
legacy API, the TSCs aren't necessarily *right*, but at least they're
in sync.

This trick falls down when restoring a guest which genuinely has been
running for less time than the 1 second of imprecision KVM allows for in
in the legacy API.  On *creation*, the first vCPU starts its TSC counting
from zero, and the subsequent vCPUs synchronize to that.  But then when
the VMM tries to restore a vCPU's intended TSC, because the VM has been
alive for less than 1 second and KVM's default TSC value for new vCPU's is
'0', the intended TSC is within a second of the last "written" TSC and KVM
incorrectly adjusts the intended TSC in an attempt to synchronize.

But further hacks can be piled onto KVM's existing hackish ABI, and
declare that the *first* value written by *userspace* (on any vCPU)
should not be subject to this "correction", i.e. KVM can assume that the
first write from userspace is not an attempt to sync up with TSC values
that only come from the kernel's default vCPU creation.

To that end: Add a flag, kvm->arch.user_set_tsc, protected by
kvm->arch.tsc_write_lock, to record that a TSC for at least one vCPU in
the VM *has* been set by userspace, and make the 1-second slop hack only
trigger if user_set_tsc is already set.

Note that userspace can explicitly request a *synchronization* of the
TSC by writing zero. For the purpose of user_set_tsc, an explicit
synchronization counts as "setting" the TSC, i.e. if userspace then
subsequently writes an explicit non-zero value which happens to be within
1 second of the previous value, the new value will be "corrected".  This
behavior is deliberate, as treating explicit synchronization as "setting"
the TSC preserves KVM's existing behaviour inasmuch as possible (KVM
always applied the 1-second "correction" regardless of whether the write
came from userspace vs. the kernel).

For 0.5KB sector size and 4KB PAGE_SIZE, this is just 1MB. For
consequence, if 'WriteMostly' is set to one of the underlying disks,
then diskcard io will be splited into 1MB and it will take a long time

dab4e1f06c bpf: Derive source IP addr via bpf_*_fib_lookup()
Extend the bpf_fib_lookup() helper by making it to return the source
IPv4/IPv6 address if the BPF_FIB_LOOKUP_SRC flag is set.

For example, the following snippet can be used to derive the desired
source IP address:

    struct bpf_fib_lookup p = { .ipv4_dst = ip4->daddr };

    ret = bpf_skb_fib_lookup(skb, p, sizeof(p),
            BPF_FIB_LOOKUP_SRC | BPF_FIB_LOOKUP_SKIP_NEIGH);
    if (ret != BPF_FIB_LKUP_RET_SUCCESS)
        return TC_ACT_SHOT;

    /* the p.ipv4_src now contains the source address */

The inability to derive the proper source address may cause malfunctions
in BPF-based dataplanes for hosts containing netdevs with more than one
routable IP address or for multi-homed hosts.

For example, Cilium implements packet masquerading in BPF. If an
egressing netdev to which the Cilium's BPF prog is attached has
multiple IP addresses, then only one [hardcoded] IP address can be used for
masquerading. This breaks connectivity if any other IP address should have
been selected instead, for example, when a public and private addresses
are attached to the same egress interface.

The change was tested with Cilium [1].

Nikolay Aleksandrov helped to figure out the IPv6 addr selection.
