If mounted with sparseread option, ceph_direct_read_write() ends up
making an unnecessarily allocation for O_DIRECT writes.

The bvecs array which is allocated in iter_get_bvecs_alloc() is leaked
and pages remain pinned if ceph_alloc_sparse_ext_map() fails.
There is no need to delay the allocation of sparse_ext map until after
the bvecs array is set up, so fix this by moving sparse_ext allocation
a bit earlier. Also, make a similar adjustment in __ceph_sync_read()
for consistency (a leak of the same kind in __ceph_sync_read() has been
addressed differently).

This patch refines the read logic in __ceph_sync_read() to ensure more
predictable and efficient behavior in various edge cases.
- Return early if the requested read length is zero or if the file size
(`i_size`) is zero.
- Initialize the index variable (`idx`) where needed and reorder some
code to ensure it is always set before use.
- Improve error handling by checking for negative return values earlier.
- Remove redundant encrypted file checks after failures. Only attempt
filesystem-level decryption if the read succeeded.
- Simplify leftover calculations to correctly handle cases where the
read extends beyond the end of the file or stops short. This can be
hit by continuously reading a file while, on another client, we keep
truncating and writing new data into it.
- This resolves multiple issues caused by integer and consequent buffer
overflow (`pages` array being accessed beyond `num_pages`):

It becomes a path component, so it shouldn't exceed NAME_MAX
characters. This was hardened in commit c152737be22b ("ceph: Use
strscpy() instead of strcpy() in __get_snap_name()"), but no actual
check was put in place.

If the full path to be built by ceph_mdsc_build_path() happens to be
longer than PATH_MAX, then this function will enter an endless (retry)
loop, effectively blocking the whole task. Most of the machine
becomes unusable, making this a very simple and effective DoS
vulnerability.
I cannot imagine why this retry was ever implemented, but it seems
rather useless and harmful to me. Let's remove it and fail with
ENAMETOOLONG instead.

In two `break` statements, the call to ceph_release_page_vector() was
missing, leaking the allocation from ceph_alloc_page_vector().
Instead of adding the missing ceph_release_page_vector() calls, the
Ceph maintainers preferred to transfer page ownership to the
`ceph_osd_request` by passing `own_pages=true` to
osd_req_op_extent_osd_data_pages(). This requires postponing the
ceph_osdc_put_request() call until after the block that accesses the
`pages`.

When function tracing and function graph tracing are both enabled (in
different instances) the "parent" of some of the function tracing events
is "return_to_handler" which is the trampoline used by function graph
tracing. To fix this, ftrace_get_true_parent_ip() was introduced that
returns the "true" parent ip instead of the trampoline.
To do this, the ftrace_regs_get_stack_pointer() is used, which uses
kernel_stack_pointer(). The problem is that microblaze does not implement
kerenl_stack_pointer() so when function graph tracing is enabled, the
build fails. But microblaze also does not enabled HAVE_DYNAMIC_FTRACE_WITH_ARGS.
That option has to be enabled by the architecture to reliably get the
values from the fregs parameter passed in. When that config is not set,
the architecture can also pass in NULL, which is not tested for in that
function and could cause the kernel to crash.

A bug was discovered where the idle shadow stacks were not initialized
for offline CPUs when starting function graph tracer, and when they came
online they were not traced due to the missing shadow stack. To fix
this, the idle task shadow stack initialization was moved to using the
CPU hotplug callbacks. But it removed the initialization when the
function graph was enabled. The problem here is that the hotplug
callbacks are called when the CPUs come online, but the idle shadow
stack initialization only happens if function graph is currently
active. This caused the online CPUs to not get their shadow stack
initialized.
The idle shadow stack initialization still needs to be done when the
function graph is registered, as they will not be allocated if function
graph is not registered.

For many use cases (e.g. container images are just fetched from remote),
performance will be impacted if underlay page cache is up-to-date but
direct i/o flushes dirty pages first.

direct I/O if supported by the underlying files.

Original sample-card assumes SND_SOC_CLOCK_IN is used for
snd_soc_dai_set_sysclk(), but someday, Codec uses SND_SOC_CLOCK_IN
and CPU uses SND_SOC_CLOCK_OUT at hw_params(), and dai->clk_direction
is used at simple_init_dai().
There is no uniformity today. Let's use dai->clk_direction for all cases.
Fortunately, almost all DAI doesn't care about "dir"
(= SND_SOC_CLOCK_IN/OUT) in .set_sysclk callback function (which is called
in snd_soc_dai_set_sysclk()), so this patch has no effect in such DAIs.
But this patch might breaks some existing Sound Card. Use
"system-clock-direction-out" property if it needs to use SND_SOC_CLOCK_OUT

commit 1f5664351410 ("ASoC: lower "no backend DAIs enabled for ... Port"
log severity") ignores -EINVAL error message on common soc_pcm_ret().
It is used from many functions, ignoring -EINVAL is over-kill.
The reason why -EINVAL was ignored was it really should only be used
upon invalid parameters coming from userspace and in that case we don't
want to log an error since we do not want to give userspace a way to do
a denial-of-service attack on the syslog / diskspace.
So don't use soc_pcm_ret() on .prepare callback is better idea.

commit a22ae72b86a4 ("ASoC: soc-core: disable route checks for legacy
devices") added card->disable_route_checks to disable route checks
for legacy devices at soc_probe_component() and snd_soc_bind_card().
And commit 6974857c2b2c ("ASoC: topology: Do not ignore route checks
when parsing graphs") tidyup soc-topology for same reason.
In snd_soc_bind_card() case, if snd_soc_dapm_add_routes() (A) error,
but has card->disable_route_checks case (B), it will indicate
dev_info() only, and then, next function (C) will be called.
Thus, "ret" will be over written, and it is handled as non-error.
static int snd_soc_bind_card(...)
{
...
(A) ret = snd_soc_dapm_add_routes(...);
if (ret < 0) {
(B) if (card->disable_route_checks) {
dev_info(...);
} else {
...
goto probe_end;
}
}
(C) ret = snd_soc_dapm_add_routes(...);
...
In soc_probe_component() case, if snd_soc_dapm_add_routes() (a)
error, and has card->disable_route_checks case (b), it will indicate
dev_info(). But there is no next function after that, this means ret is
still indicating error, and will not be over written.
So error handline (c) will be handled, and will return error (d)
static int soc_probe_component(...)
{
...
(a) ret = snd_soc_dapm_add_routes(...);
if (ret < 0) {
(b) if (card->disable_route_checks) {
dev_info(...);
} else {
...
goto err_probe;
}
}
/* see for_each_card_components */
list_add(...);
err_probe:
(c) if (ret < 0)
soc_remove_component(...);
(d) return ret;
}
In soc_tplg_dapm_graph_elems_load() case, snd_soc_dapm_add_routes()
is called in for loop (1). if it was error (2), and doesn't have
card->disable_route_checks case flag (3), it will break from loop.
If card has flag, it will indicate dev_info() and handled as non-error.
But ret is still indicating error in this case. If this error happen
in last of loop, if will return error (4).
static int soc_tplg_dapm_graph_elems_load(...)
{
...
(1) for (i = 0; i < count; i++) {
...
(2) ret = snd_soc_dapm_add_routes(...);
if (ret) {
(3) if (!dapm->card->disable_route_checks) {
dev_err(...);
break;
}
dev_info(...);
}
}
(4) return ret;
}
This patch set "ret = 0" for each case.

This adds a match entry for using all the amps on a CDB35L56-EIGHT-C board
without the CS42L43 codec. Configuration is:
SDW0: 4x CS35L56 (OUT1, OUT2, OUT3, OUT4)
SDW1: 4x CS35L56 (OUT5, OUT6, OUT7, OUT8)
Speaker playback and amp feedback are aggregated.

This adds a match for the CDB35L56-EIGHT-C board with SmartCodec and
SmartAmp speakers aggregated.
The configuration is:
SDW0: CS35L56 x2 (SmartAmp) using OUT1 and OUT2
SDW1: CS35L56 x2 (SmartAmp) using OUT7 and OUT8
SDW3: CS42L43 (SmartJack, SmartMic, SmartAmp)
CS35L56 and CS42L43 Speaker playback is aggregated across all 3 buses.
The device addresses and reset arrangements of the EIGHT-C board are
quirky hence the use of non-contiguous outputs OUT1,2,7,8.

This adds match entries for the eight CS35L56 amps on the Cirrus Logic
CDB35L56-EIGHT-C board. Speaker playback and amp feedback are aggregated
across all amps on both SoundWire buses.
The mapping of SoundWire addresses to AMPn numbers matches the actual
order of amps on the EIGHT-C board. The SoundWire unique ID is in reverse
order for amps 1..4 on these boards, and the amp resets are paired
1+8, 2+7, 3+6, 4+5.
This then makes the entries from cs35l56_sdw_eight_1_4_fb_adr and
cs35l56_sdw_eight_5_8_fb_adr match the way the amp resets are paired on
the EIGHT-C board.
[0] = 1 + 8
[1] = 2 + 7
[3] = 3 + 6
[4] = 4 + 5

Alexandre observed a warning emitted from pci_msi_setup_msi_irqs() on a
RISCV platform which does not provide PCI/MSI support:
WARNING: CPU: 1 PID: 1 at drivers/pci/msi/msi.h:121 pci_msi_setup_msi_irqs+0x2c/0x32
__pci_enable_msix_range+0x30c/0x596
pci_msi_setup_msi_irqs+0x2c/0x32
pci_alloc_irq_vectors_affinity+0xb8/0xe2
RISCV uses hierarchical interrupt domains and correctly does not implement
the legacy fallback. The warning triggers from the legacy fallback stub.
That warning is bogus as the PCI/MSI layer knows whether a PCI/MSI parent
domain is associated with the device or not. There is a check for MSI-X,
which has a legacy assumption. But that legacy fallback assumption is only
valid when legacy support is enabled, but otherwise the check should simply
return -ENOTSUPP.
Loongarch tripped over the same problem and blindly enabled legacy support
without implementing the legacy fallbacks. There are weak implementations
which return an error, so the problem was papered over.
Correct pci_msi_domain_supports() to evaluate the legacy mode and add
the missing supported check into the MSI enable path to complete it.

When USB-C monitor is connected directly to Intel Barlow Ridge host, it
goes into "redrive" mode that basically routes the DisplayPort signals
directly from the GPU to the USB-C monitor without any tunneling needed.
However, the host router must be powered on for this to work. Aaron
reported that there are a couple of cases where this will not work with
the current code:
- Booting with USB-C monitor plugged in.
- Plugging in USB-C monitor when the host router is in sleep state
(runtime suspended).
- Plugging in USB-C device while the system is in system sleep state.
In all these cases once the host router is runtime suspended the picture
on the connected USB-C display disappears too. This is certainly not
what the user expected.
For this reason improve the redrive mode handling to keep the host
router from runtime suspending when detect that any of the above cases
is happening.

Since commit 0a77d947f599 ("ksmbd: check outstanding simultaneous SMB
operations"), ksmbd enforces a maximum number of simultaneous operations
for a connection. The problem is that reaching the limit causes ksmbd to
close the socket, and the client has no indication that it should have
slowed down.
This behaviour can be reproduced by setting "smb2 max credits = 128" (or
lower), and transferring a large file (25GB).
smbclient fails as below:
$ smbclient //192.168.1.254/testshare -U user%pass
smb: \> put file.bin
cli_push returned NT_STATUS_USER_SESSION_DELETED
putting file file.bin as \file.bin smb2cli_req_compound_submit:
Insufficient credits. 0 available, 1 needed
NT_STATUS_INTERNAL_ERROR closing remote file \file.bin
smb: \> smb2cli_req_compound_submit: Insufficient credits. 0 available,
1 needed
Windows clients fail with 0x8007003b (with smaller files even).
Fix this by delaying reading from the socket until there's room to
allocate a request. This effectively applies backpressure on the client,
so the transfer completes, albeit at a slower rate.

The existing linked list based implementation of how ts tags are
assigned and managed is unsafe against concurrency and corner cases:
- element addition in tx processing can race against element removal
in ts queue completion,
- element removal in ts queue completion can race against element
removal in device close,
- if a large number of frames gets added to tx queue without ts queue
completions in between, elements with duplicate tag values can get
added.
Use a different implementation, based on per-port used tags bitmaps and
saved skb arrays.
Safety for addition in tx processing vs removal in ts completion is
provided by:
tag = find_first_zero_bit(...);
smp_mb();
<write rdev->ts_skb[tag]>
set_bit(...);
vs
<read rdev->ts_skb[tag]>
smp_mb();
clear_bit(...);
Safety for removal in ts completion vs removal in device close is
provided by using atomic read-and-clear for rdev->ts_skb[tag]:
ts_skb = xchg(&rdev->ts_skb[tag], NULL);
if (ts_skb)
<handle it>
