As per listxattr(2):
On success, a nonnegative number is returned indicating the size
of the extended attribute name list. On failure, -1 is returned
and errno is set appropriately.
In SMB1, when the server returns an empty EA list through a listxattr(),
it will correctly return 0 as there are no EAs for the given file.
However, in SMB2+, it returns -ENODATA in listxattr() which is wrong since
the request and response were sent successfully, although there's no actual
EA for the given file.
This patch fixes listxattr() for SMB2+ by returning 0 in cifs_listxattr()
when the server returns an empty list of EAs.

The data buffer allocated on the stack can't be DMA'ed, ib_dma_map_page will
return an invalid DMA address for a buffer on stack. Even worse, this
incorrect address can't be detected by ib_dma_mapping_error. Sending data
from this address to hardware will not fail, but the remote peer will get
junk data.
Fix this by allocating the request on the heap in smb3_validate_negotiate.
Changes in v2:
Removed duplicated code on freeing buffers on function exit.

USB controller ASM1042 stops working after commit de3ef1eb1cd0 (PM /
core: Drop run_wake flag from struct dev_pm_info).
The device in question is not power managed by platform firmware,
furthermore, it only supports PME# from D3cold:
Capabilities: [78] Power Management version 3
Flags: PMEClk- DSI- D1- D2- AuxCurrent=55mA PME(D0-,D1-,D2-,D3hot-,D3cold+)
Status: D0 NoSoftRst+ PME-Enable- DSel=0 DScale=0 PME-
Before commit de3ef1eb1cd0, the device never gets runtime suspended.
After that commit, the device gets runtime suspended to D3hot, which can
not generate any PME#.
usb_hcd_pci_probe() unconditionally calls device_wakeup_enable(), hence
device_can_wakeup() in pci_dev_run_wake() always returns true.
So pci_dev_run_wake() needs to check PME wakeup capability as its first
condition.
In addition, change wakeup flag passed to pci_target_state() from false
to true, because we want to find the deepest state different from D3cold
that the device can still generate PME#. In this case, it's D0 for the
device in question.

If the next_freq field of struct sugov_policy is set to UINT_MAX,
it shouldn't be used for updating the CPU frequency (this is a
special "invalid" value), but after commit b7eaf1aab9f8 (cpufreq:
schedutil: Avoid reducing frequency of busy CPUs prematurely) it
may be passed as the new frequency to sugov_update_commit() in
sugov_update_single().
Fix that by adding an extra check for the special UINT_MAX value
of next_freq to sugov_update_single().

Since commit a92a08499b1f "r8169: improve runtime pm in general and
suspend unused ports" interfaces w/o link are runtime-suspended after
10s. On systems where drivers take longer to load this can lead to the
situation that the interface is runtime-suspended already when it's
initially brought up.
This shouldn't be a problem because rtl_open() resumes MAC/PHY.
However with at least one chip version the interface doesn't properly
come up, as reported here:
https://bugzilla.kernel.org/show_bug.cgi?id=199549
The vendor driver uses a delay to give certain chip versions some
time to resume before starting the PHY configuration. So let's do
the same. I don't know which chip versions may be affected,
therefore apply this delay always.
This patch was reported to fix the issue for RTL8168h.
I was able to reproduce the issue on an Asus H310I-Plus which also
uses a RTL8168h. Also in my case the patch fixed the issue.

Fix `[drm:intel_enable_lvds] *ERROR* timed out waiting for panel to
power on` in kernel log at boot time.
Toshiba Satellite Z930 laptops needs between 1 and 2 seconds to power
on its screen during Intel i915 DRM initialization. This currently
results in a `[drm:intel_enable_lvds] *ERROR* timed out waiting for
panel to power on` message appearing in the kernel log during boot
time and when stopping the machine.
This change increases the timeout of the `intel_enable_lvds` function
from 1 to 5 seconds, letting enough time for the Satellite 930 LCD
screen to power on, and suppressing the error message from the kernel
log.
This patch has been successfully tested on Linux 4.14 running on a
Toshiba Satellite Z930.
[vsyrjala: bump the timeout from 2 to 5 seconds to match the DP
code and properly cover the max hw timeout of ~4 seconds, and
drop the comment about the specific machine since this is not
a particulary surprising issue, nor specific to that one machine]

readout
During state readout we first read out the pipe src size, store
that information in the user mode h/vdisplay, but later on we overwrite
that with the actual crtc timings. That makes our read out crtc state
inconsistent with itself when the BIOS has enabled the panel fitter to
scale the pipe contents. Let's preserve the pipe src size based
information in the user mode to make things consistent again.
This fixes a problem introduced by commit a2936e3d9a9c ("drm/i915:
Use drm_mode_get_hv_timing() to populate plane clip rectangle")
where the inconsistent state is now leading the plane clipping code
to report a failure on account the plane dst coordinates not matching
the user mode size. Previously we did the plane clipping based on
the pipe src size instead and thus never noticed the inconsistency.
The failure manifests as a WARN:

On intel_dp_compute_config() we were calculating the needed vco
for eDP on gen9 and we stashing it in
intel_atomic_state.cdclk.logical.vco
However few moments later on intel_modeset_checks() we fully
replace entire intel_atomic_state.cdclk.logical with
dev_priv->cdclk.logical fully overwriting the logical desired
vco for eDP on gen9.
So, with wrong VCO value we end up with wrong desired cdclk, but
also it will raise a lot of WARNs: On gen9, when we read
CDCLK_CTL to verify if we configured properly the desired
frequency the CD Frequency Select bits [27:26] == 10b can mean
337.5 or 308.57 MHz depending on the VCO. So if we have wrong
VCO value stashed we will believe the frequency selection didn't
stick and start to raise WARNs of cdclk mismatch.

In commit 88462d2a7830 ("can: flexcan: Remodel FlexCAN register r/w APIs
for big endian FlexCAN controllers.") the following logic was
implemented:
if the dt property "big-endian" is given or
the device is compatible to "fsl,p1010-flexcan":
use big-endian mode;
else
use little-endian mode;
This relies on commit d50f4630c2e1 ("arm: dts: Remove p1010-flexcan
compatible from imx series dts") which was applied a few commits later.
Without this commit (or an old device tree used for booting a new
kernel) the flexcan devices on i.MX25, i.MX28, i.MX35 and i.MX53 match
the 'the device is compatible to "fsl,p1010-flexcan"' test and so are
switched erroneously to big endian mode.
Instead of the check above put a quirk in devtype data and rely on
of_match_device yielding the most compatible match

bus-off is usually caused by hardware malfunction or configuration error
(baud rate mismatch) and causes a complete loss of communication.
Increase the "bus-off" message's severity from netdev_dbg() to
netdev_info() to make it visible to the user.
A can interface going into bus-off is similar in severity to ethernet's
"Link is Down" message, which is also printed at info level.
It is debatable whether the the "restarted" message should also be
changed to netdev_info() to make the interface state changes
comprehensible from the kernel log. I have chosen to keep the
"restarted" message at dbg for now as the "bus-off" message should be
enough for the user to notice and investigate the problem.

First is that driver should declare valid vlan_features
Second fix is about correct allocation of MSI interrupts on some systems.

Driver should use pci_alloc_irq_vectors return value to correct number
of allocated vectors and napi instances. Otherwise it'll panic later
in pci_irq_vector.
Driver also should allow more than one MSI vectors to be allocated.
Error return path from pci_alloc_irq_vectors is also fixed to revert
resources in a correct sequence when error happens.

Most of the mv88e6xxx switches have the PHYs at address 0, 1, 2, ...
The 6341 however has the PHYs at 0x10, 0x11, 0x12. Add a parameter to
the info structure for this base address.
Testing of 6f88284f3bd7 ("net: dsa: mv88e6xxx: Add MDIO interrupts for

Now sctp only delays the authentication for the normal cookie-echo
chunk by setting chunk->auth_chunk in sctp_endpoint_bh_rcv(). But
for the duplicated one with auth, in sctp_assoc_bh_rcv(), it does
authentication first based on the old asoc, which will definitely
fail due to the different auth info in the old asoc.
The duplicated cookie-echo chunk will create a new asoc with the
auth info from this chunk, and the authentication should also be
done with the new asoc's auth info for all of the collision 'A',
'B' and 'D'. Otherwise, the duplicated cookie-echo chunk with auth
will never pass the authentication and create the new connection.
This issue exists since very beginning, and this fix is to make
sctp_assoc_bh_rcv() follow the way sctp_endpoint_bh_rcv() does
for the normal cookie-echo chunk to delay the authentication.
While at it, remove the unused params from sctp_sf_authenticate()
and define sctp_auth_chunk_verify() used for all the places that
do the delayed authentication.

During boot, the HYPERVISOR_shared_info page gets remapped to make it work
with KASLR. This means that any pointer derived from it needs to be
adjusted.
The only value that this applies to is the vcpu_info pointer for VCPU 0.
For PV and HVM with the callback vector feature, this gets done via the
smp_ops prepare_boot_cpu callback. Older Xen versions do not support the
HVM callback vector, so there is no Xen-specific smp_ops set up in that
scenario. So, the vcpu_info pointer for VCPU 0 never gets set to the proper
value, and the first reference of it will be bad. Fix this by resetting it
immediately after the remap.
