The data in NVRAM is not guaranteed to be NUL terminated. Since
snprintf expects byte-stream to accommodate null byte, the CHAP secret
is truncated. Use sprintf instead of snprintf to fix the truncation of
CHAP name and secret.

When a request times out we set the io_req flag BNX2FC_FLAG_IO_COMPL so
that if a subsequent completion comes in on that task ID we will ignore
it. The issue is that in the check for this flag there is a missing
return so we will continue to process a request which may have already
been returned to the ownership of the SCSI layer. This can cause
unpredictable results.
Solution is to add in the missing return.

[ Upstream commit b7007dbccd ]
When exiting a transformation, the cra_exit() helper is called in each
driver providing one. The Inside Secure SafeXcel driver has one, which
is responsible of freeing some areas and of sending one invalidation
request to the crypto engine, to invalidate the context that was used
during the transformation.
We could see in some setups (when lots of transformations were being
used with a short lifetime, and hence lots of cra_exit() calls) NULL
pointer dereferences and other weird issues. All these issues were
coming from accessing the tfm context.
The issue is the invalidation request completion is checked using a
wait_for_completion_interruptible() call in both the cipher and hash
cra_exit() helpers. In some cases this was interrupted while the
invalidation request wasn't processed yet. And then cra_exit() returned,
and its caller was freeing the tfm instance. Only then the request was
being handled by the SafeXcel driver, which lead to the said issues.
This patch fixes this by using wait_for_completion() calls in these
specific cases.

Commit 8f18c8a48b ("staging: lustre: lmv: separate master object

particularly when LMV_HASH_FLAG_MIGRATION is not set.
Previously lsm_md_oinfo[0].lmo_root was always a borrowed
inode reference and didn't need to by iput().
Since the change, that special case only applies when
LMV_HASH_FLAG_MIGRATION is set
In the upstream (lustre-release) version of this patch [Commit
60e07b972114 ("LU-4690 lod: separate master object with master
stripe")] the for loop in the lmv_unpack_md() was changed to count
from 0 and to ignore entry 0 if LMV_HASH_FLAG_MIGRATION is set.
In the patch that got applied to Linux, that change was missing,
so lsm_md_oinfo[0].lmo_root is never iput().
This results in a "VFS: Busy inodes" warning at unmount.

When handling an OS descriptor request, one of the first operations is
to zero out the request buffer using the wLength from the setup packet.
There is no bounds checking, so a wLength > 4096 would clobber memory
adjacent to the request buffer. Fix this by taking the min of wLength
and the request buffer length prior to the memset. While at it, define
the buffer length in a header file so that magic numbers don't appear
throughout the code.
When returning data to the host, the data length should be the min of
the wLength and the valid data we have to return. Currently we are
returning wLength, thus requests for a wLength greater than the amount
of data in the OS descriptor buffer would return invalid (albeit zero'd)
data following the valid descriptor data. Fix this by counting the
number of bytes when constructing the data and using this when
determining the length of the request.

submitted asynchronously and on URB completion the received data is copied
to the userspace buffer associated with the read operation.
This is done from a kernel worker thread invoking copy_to_user() (through
copy_to_iter()). And while the user space process memory is made available
to the kernel thread using use_mm(), some architecture require in addition
to this that the operation runs with USER_DS set. Otherwise the userspace
memory access will fail.

Address this by placing a set_fs(USER_DS) before of the copy operation
and revert it again once the copy operation has finished.
This patch is analogous to commit d7ffde35e3 ("vhost: use USER_DS in
vhost_worker thread") which addresses the same underlying issue.

[ Upstream commit 946ef68ad4 ]
Some UDC drivers (like the DWC3) expect that the response to a setup()
request is queued from within the setup function itself so that it is
available as soon as setup() has completed.
Upon receiving a setup request the function fs driver creates an event that
is made available to userspace. And only once userspace has acknowledged
that event the response to the setup request is queued.
So it violates the requirement of those UDC drivers and random failures can
be observed. This is basically a race condition and if userspace is able to
read the event and queue the response fast enough all is good. But if it is
not, for example because other processes are currently scheduled to run,
the USB host that sent the setup request will observe an error.
To avoid this the gadget framework provides the USB_GADGET_DELAYED_STATUS
return code. If a setup() callback returns this value the UDC driver is
aware that response is not yet available and can uses the appropriate
methods to handle this case.
Since in the case of function fs the response will never be available when
the setup() function returns make sure that this status code is used.
This fixed random occasional failures that were previously observed on a
DWC3 based system under high system load.

Added missing GUSBCFG programming in host mode, which fixes
transaction errors issue on HiKey and Altera Cyclone V boards.
These field even if was programmed in device mode (in function
dwc2_hsotg_core_init_disconnected()) will be resetting to POR values
after core soft reset applied.
So, each time when switching to host mode required to set this field
to correct value.

set udev->slot_id to zero when disabling and freeing the xhci slot.
Prevents usb core from calling xhci with a stale slot id.
xHC controller may be reset during resume to recover from some error.
All slots are unusable as they are disabled and freed.
xhci driver starts slot enumeration again from 1 in the order they are
enabled. In the worst case a stale udev->slot_id for one device matches
a newly enabled slot_id for a different device, causing us to
perform a action on the wrong device.

[ Upstream commit 71426535f4 ]
Add native DSD support quirk for Luxman DA-06 DAC, by adding the
PID/VID 1852:5065.
Rename "is_marantz_denon_dac()" function to "is_itf_usb_dsd_2alts_dac()"
to cover broader device family sharing the same USB audio
implementation(*).
For the same reason, rename "is_teac_dsd_dac()" function to
"is_itf_usb_dsd_3alts_dac()".
(*)
These devices have the same USB controller "ITF-USB DSD", supplied by
INTERFACE Co., Ltd.
"ITF-USB DSD" USB controller has two patterns,
Pattern 1. (2 altsets version)
- Altset 0: for control
- Altset 1: for stream (S32)
- Altset 2: for stream (S32, DSD_U32)
Pattern 2. (3 altsets version)
- Altset 0: for control
- Altset 1: for stream (S16)
- Altset 2: for stream (S32)
- Altset 3: for stream (S32, DSD_U32)
"is_itf_usb_dsd_2alts_dac()" returns true, if the DAC has "Pattern 1"
USB controller, and "is_itf_usb_dsd_3alts_dac()" returns true, if
"Pattern2".

[ Upstream commit d56e57ca03 ]
This patch reverts the commit 835e4241e7 ("usb: host: xhci-plat:
enable clk in resume timing") because this driver also has runtime PM
and the commit 560869100b ("clk: renesas: cpg-mssr: Restore module
clocks during resume") will restore the clock on R-Car H3 environment.
If the xhci_plat_suspend() disables the clk, the system cannot enable
the clk in resume like the following behavior:
< In resume >
- genpd_resume_noirq() runs and enable the clk (enable_count = 1)
- cpg_mssr_resume_noirq() restores the clk register.
-- Since the clk was disabled in suspend, cpg_mssr_resume_noirq()
will disable the clk and keep the enable_count.
- Even if xhci_plat_resume() calls clk_prepare_enable(), since
the enable_count is 1, the clk will be not enabled.
After this patch is applied, the cpg-mssr driver will save the clk
as enable, so the clk will be enabled in resume.
