Add tests to verify CID collision rules across different vsock namespace
modes.
1. Two VMs with the same CID cannot start in different global namespaces
(ns_global_same_cid_fails)
2. Two VMs with the same CID can start in different local namespaces
(ns_local_same_cid_ok)
3. VMs with the same CID can coexist when one is in a global namespace
and another is in a local namespace (ns_global_local_same_cid_ok and
ns_local_global_same_cid_ok)
The tests ns_global_local_same_cid_ok and ns_local_global_same_cid_ok
make sure that ordering does not matter.
The tests use a shared helper function namespaces_can_boot_same_cid()
that attempts to start two VMs with identical CIDs in the specified
namespaces and verifies whether VM initialization failed or succeeded.

Add tests for the /proc/sys/net/vsock/{ns_mode,child_ns_mode}
interfaces. Namely, that they accept/report "global" and "local" strings
and enforce their access policies.
Start a convention of commenting the test name over the test
description. Add test name comments over test descriptions that existed
before this convention.
Add a check_netns() function that checks if the test requires namespaces
and if the current kernel supports namespaces. Skip tests that require
namespaces if the system does not have namespace support.
This patch is the first to add tests that do *not* re-use the same
shared VM. For that reason, it adds a run_ns_tests() function to run
these tests and filter out the shared VM tests.

Replace /proc/net parsing with ss(8) for detecting listening sockets in
wait_for_listener() functions and add support for TCP, VSOCK, and Unix
socket protocols.
The previous implementation parsed /proc/net/tcp using awk to detect
listening sockets, but this approach could not support vsock because
vsock does not export socket information to /proc/net/.
Instead, use ss so that we can detect listeners on tcp, vsock, and unix.
The protocol parameter is now required for all wait_for_listener family
functions (wait_for_listener, vm_wait_for_listener,
host_wait_for_listener) to explicitly specify which socket type to wait
for.
ss is added to the dependency check in check_deps().

Associate reply packets with the sending socket. When vsock must reply
with an RST packet and there exists a sending socket (e.g., for
loopback), setting the skb owner to the socket correctly handles
reference counting between the skb and sk (i.e., the sk stays alive
until the skb is freed).
This allows the net namespace to be used for socket lookups for the
duration of the reply skb's lifetime, preventing race conditions between
the namespace lifecycle and vsock socket search using the namespace
pointer.

Add netns logic to vsock core. Additionally, modify transport hook

*_seqpacket_allow()).
Namespaces are supported primarily by changing socket lookup functions
(e.g., vsock_find_connected_socket()) to take into account the socket
namespace and the namespace mode before considering a candidate socket a
"match".
This patch also introduces the sysctl /proc/sys/net/vsock/ns_mode to
report the mode and /proc/sys/net/vsock/child_ns_mode to set the mode
for new namespaces.
Add netns functionality (initialization, passing to transports, procfs,
etc...) to the af_vsock socket layer. Later patches that add netns
support to transports depend on this patch.
This patch changes the allocation of random ports for connectible vsocks
in order to avoid leaking the random port range starting point to other
namespaces.
dgram_allow(), stream_allow(), and seqpacket_allow() callbacks are
modified to take a vsk in order to perform logic on namespace modes. In
future patches, the net will also be used for socket
lookups in these functions.

Lan9645x is the first chip supported by this driver where the pin stride
is different from the alt mode stride. With 51 pins and up to 7 alt
modes, we have stride = 2 and alt_mode_stride = 3.
The current REG_ALT macro has the implicit assumption that these numbers
are equal, so it does not work for lan9645x.
The pin stride is the 'stride' variable in the driver. It is the size
of certain register groups which depends on the number of pins supported
by the device. Generally we have stride = DIV_ROUND_UP(npins, 32). E.g:
GPIO_OUT_SET0
GPIO_OUT_SET1
...
GPIO_OUT_SETn
The alt mode registers are further replicated by the number of bits
necessary to represent the alt mode. For instance if we need 3 bits to
represent the alt mode:
GPIO_ALT0[0-2]
GPIO_ALT1[0-2]
To set alt mode 3 on pin 12, it is necessary to perform writes
GPIO_ALT0[0] |= BIT(12)
GPIO_ALT0[1] |= BIT(12)
GPIO_ALT0[2] &= ~BIT(12)
The stride and alt mode stride are used by the REG_ALT macro to
calculate the alt mode register address for a given pin.
This adds the option to specify n_alt_modes, which is used to set
info->altm_stride. The default value is info->stride, to make sure
existing devices are unaffected by this change.

Marking the whole controller as sleeping due to the pinctrl calls in the
.direction_{input,output} callbacks has the unfortunate side effect that
legitimate invocations of .get and .set, which cannot themselves sleep,
in atomic context now spew WARN()s from gpiolib.
However, as Heiko points out, the driver doing this is a bit silly to
begin with, as the pinctrl .gpio_set_direction hook doesn't even care
about the direction, the hook is only used to claim the mux. And sure
enough, the .gpio_request_enable hook exists to serve this very purpose,
so switch to that and remove the problematic business entirely.

Add mixer control support for the Focusrite Forte (USB ID 0x1235:0x8010),
an older USB audio interface that predates the Scarlett 2nd generation.
The Forte uses UAC2_CS_MEM (bRequest=0x03) for its input controls rather
than the standard UAC2_CS_CUR (0x01) used by Scarlett devices. This patch
adds Forte-specific control handlers that use the correct USB protocol.
Features implemented:
- Input source selection (Mic/Line/Inst) for both channels
- High pass filter switch
- 48V phantom power switch
- Phase invert switch
- Pad switch
- Preamp gain control (0-42 range, ~0-75dB)
- Matrix mixer controls (6 inputs x 4 outputs)
- Output volume and mute controls
The device is registered via mixer_quirks.c and uses the existing
mixer_scarlett.c infrastructure with Forte-specific additions.

Currently, the CPPC Frequency Invariance Engine (FIE) is invoked from the
scheduler tick but defers the update of arch_freq_scale to a separate
thread because cppc_get_perf_ctrs() would sleep if the CPC regs are in PCC.
However, this deferred update mechanism is unnecessary and introduces extra
overhead for non-PCC register spaces (e.g. System Memory or FFH), where
accessing the regs won't sleep and can be safely performed from the tick
context.
Furthermore, with the CPPC FIE registered, it throws repeated warnings of
"cppc_scale_freq_workfn: failed to read perf counters" on our platform with
the CPC regs in System Memory and a power-down idle state enabled. That's
because the remote CPU can be in a power-down idle state, and reading its
perf counters returns 0. Moving the FIE handling back to the scheduler
tick process makes the CPU handle its own perf counters, so it won't be
idle and the issue would be inherently solved.
To address the above issues, update arch_freq_scale directly in ticks for
non-PCC regs and keep the deferred update mechanism for PCC regs.
