[ Upstream commit 89e637c19b2441aabc8dbf22a8745b932fd6996e ]
Although the code for residual handling in the SRP initiator follows the
SCSI documentation, that documentation has never been correct. Because
scsi_finish_command() starts from the data buffer length and subtracts the
residual, scsi_set_resid() must not be called if a residual overflow
occurs. Hence remove the scsi_set_resid() calls from the SRP initiator if a
residual overflow occurrs.

[ Upstream commit 5eda42aebb7668b4dcff025cd3ccb0d3d7c53da6 ]
The function mxs_phy_is_otg_host() will return true if OTG_ID_VALUE is
0 at USBPHY_CTRL register. However, OTG_ID_VALUE will not reflect the real
state if the ID pin is float, such as Host-only or Type-C cases. The value
of OTG_ID_VALUE is always 1 which means device mode.
This patch will fix the issue by judging the current mode based on
last_event. The controller will update last_event in time.

[ Upstream commit cf10b0bb503c974ba049d6f888b21178be20a962 ]
If we encounter any error in the vdec_msg_queue_init() then we need
to set "msg_queue->wdma_addr.size = 0;". Normally, this is done
inside the vdec_msg_queue_deinit() function. However, if the
first call to allocate &msg_queue->wdma_addr fails, then the
vdec_msg_queue_deinit() function is a no-op. For that situation, just
set the size to zero explicitly and return.
There were two other error paths which did not clean up before returning.
Change those error paths to goto mem_alloc_err.

[ Upstream commit be40f524b6edac4fb9a98ef79620fd9b9497a998 ]
The "lat_buf->private_data" needs to be set to NULL to prevent a
double free. How this would happen is if vdec_msg_queue_init() failed
twice in a row and on the second time it failed earlier than on the
first time.
The vdec_msg_queue_init() function has a loop which does:
for (i = 0; i < NUM_BUFFER_COUNT; i++) {
Each iteration initializes one element in the msg_queue->lat_buf[] array
and then the clean up function vdec_msg_queue_deinit() frees each
element of the msg_queue->lat_buf[] array. This clean up code relies
on the assumption that every element is either initialized or zeroed.
Leaving a freed pointer which is non-zero breaks the assumption.

[ Upstream commit b3b4c9d3cb3bf8725a3ded26f7042b1a37f25333 ]
Commit f100ce3bbd6a ("media: verisilicon: Fix crash when probing
encoder") removed vpu_fmt from hantro_try_fmt(), since it was
initialized from vpu_dst_fmt, which may not be initialized, when TRY_FMT
is called. It was replaced by fmt, which is found using the pixelformat.
For the encoder, this changed the fmt to contain the raw format instead
of the coded format. The format constraints as of fmt->frmsize are only
valid for the coded format and are 0 for the raw formats. Therefore, the
size of a encoder OUTPUT device is constrained to 0 and the
v4l2-compliance tests for G_FMT, TRY_FMT, and SET_FMT fail.
Bring back vpu_fmt to use the coded format on an encoder OUTPUT device,
but initialize it using the currently set pixelformat on dst_fmt, which
is the coded format on an encoder.

[ Upstream commit bad5b6e34ffbaacc77ad28a0f482e33b3929e635 ]
LOOPBACK and NONE (tunnel) devices have all-zero MAC addresses.
Currently, siw_device_create() falls back to copying the IB device's
name in those cases, because an all-zero MAC address breaks the RDMA
core address resolution mechanism.
However, at the point when siw_device_create() constructs a GID, the
ib_device::name field is uninitialized, leaving the MAC address to
remain in an all-zero state.
Fabricate a random artificial GID for such devices, and ensure this
artificial GID is returned for all device query operations.

[ Upstream commit 6df63b7ebdaf5fcd75dceedf6967d0761e56eca1 ]
The physical address to the directory table is currently encoded using
the following bit layout for IOMMU v2.
31:12 - Address bit 31:0
11: 4 - Address bit 39:32
This is also the bit layout used by the vendor kernel.
However, testing has shown that addresses to the directory/page tables
and memory pages are all encoded using the same bit layout.
IOMMU v1:
31:12 - Address bit 31:0
IOMMU v2:
31:12 - Address bit 31:0
11: 8 - Address bit 35:32
7: 4 - Address bit 39:36
Change to use the mk_dtentries ops to encode the directory table address
correctly. The value written to DTE_ADDR may include the valid bit set,
a bit that is ignored and DTE_ADDR reg read it back as 0.
This also update the bit layout comment for the page address and the
number of nybbles that are read back for DTE_ADDR comment.
These changes render the dte_addr_phys and dma_addr_dte ops unused and
is removed.

When unbinding pasid - a race condition exists vs outstanding page faults.
To prevent this, the pasid_state object contains a refcount.
* set to 1 on pasid bind
* incremented on each ppr notification start

* decremented on pasid unbind
Since refcount_dec assumes that refcount will never reach 0:

The supported ad5820 and ad5821 VCMs both use a single 16 bit register
which is written by sending 2 bytes with the data directly after sending

[ Upstream commit a828002f38c5ee49d3f0c0e64c0f0caa1aec8dc2 ]
OV5640 will output abnormal image data when work at low resolution
(320x240, 176x144 and 160x120) after switching from high resolution,
such as 1080P, the time interval between high and low switching must
be less than 1000ms in order to OV5640 don't enter suspend state during
the time.
The reason is by 0x3824 value don't restore to initialize value when
do resolution switching. In high resolution setting array, 0x3824 is
set to 0x04, but low resolution setting array remove 0x3824 in commit
db15c1957a2d ("media: ov5640: Remove duplicated mode settings"). So
when do resolution switching from high to low, such as 1080P to 320x240,
and the time interval is less than auto suspend delay time which means
global initialize setting array will not be loaded, the output image
data are abnormal. Hence move 0x3824 from ov5640_init_setting[] table
to ov5640_setting_low_res[] table and also move 0x4407 0x460b, 0x460c
to avoid same issue.

[ Upstream commit eac030b22ea12cdfcbb2e941c21c03964403c63f ]
lppaca_shared_proc() takes a pointer to the lppaca which is typically
accessed through get_lppaca(). With DEBUG_PREEMPT enabled, this leads
to checking if preemption is enabled, for example:
BUG: using smp_processor_id() in preemptible [00000000] code: grep/10693
caller is lparcfg_data+0x408/0x19a0
CPU: 4 PID: 10693 Comm: grep Not tainted 6.5.0-rc3 #2
Call Trace:
dump_stack_lvl+0x154/0x200 (unreliable)
check_preemption_disabled+0x214/0x220
lparcfg_data+0x408/0x19a0
...
This isn't actually a problem however, as it does not matter which
lppaca is accessed, the shared proc state will be the same.
vcpudispatch_stats_procfs_init() already works around this by disabling
preemption, but the lparcfg code does not, erroring any time
/proc/powerpc/lparcfg is accessed with DEBUG_PREEMPT enabled.
Instead of disabling preemption on the caller side, rework
lppaca_shared_proc() to not take a pointer and instead directly access
the lppaca, bypassing any potential preemption checks.

[ Upstream commit cd24e2a60af633f157d7e59c0a6dba64f131c0b1 ]
Fix an information leak where an uninitialized hole in struct
vfio_iommu_type1_info_cap_migration on the stack is exposed to userspace.
The definition of struct vfio_iommu_type1_info_cap_migration contains a hole as
shown in this pahole(1) output:
struct vfio_iommu_type1_info_cap_migration {
struct vfio_info_cap_header header; /* 0 8 */
__u32 flags; /* 8 4 */
/* XXX 4 bytes hole, try to pack */
__u64 pgsize_bitmap; /* 16 8 */
__u64 max_dirty_bitmap_size; /* 24 8 */
/* size: 32, cachelines: 1, members: 4 */
/* sum members: 28, holes: 1, sum holes: 4 */
/* last cacheline: 32 bytes */
};
The cap_mig variable is filled in without initializing the hole:
static int vfio_iommu_migration_build_caps(struct vfio_iommu *iommu,
struct vfio_info_cap *caps)
{
struct vfio_iommu_type1_info_cap_migration cap_mig;
cap_mig.header.id = VFIO_IOMMU_TYPE1_INFO_CAP_MIGRATION;
cap_mig.header.version = 1;
cap_mig.flags = 0;
/* support minimum pgsize */
cap_mig.pgsize_bitmap = (size_t)1 << __ffs(iommu->pgsize_bitmap);
cap_mig.max_dirty_bitmap_size = DIRTY_BITMAP_SIZE_MAX;
return vfio_info_add_capability(caps, &cap_mig.header, sizeof(cap_mig));
}
The structure is then copied to a temporary location on the heap. At this point
it's already too late and ioctl(VFIO_IOMMU_GET_INFO) copies it to userspace
later:
int vfio_info_add_capability(struct vfio_info_cap *caps,
struct vfio_info_cap_header *cap, size_t size)
{
struct vfio_info_cap_header *header;
header = vfio_info_cap_add(caps, size, cap->id, cap->version);
if (IS_ERR(header))
return PTR_ERR(header);
memcpy(header + 1, cap + 1, size - sizeof(*header));
return 0;
}

[ Upstream commit 4dd432d985ef258e3bc436e568fba4b987b59171 ]
Reconfiguring the clock divider to the exact same value is observed
on an i.MX8MN to often cause a longer than usual clock pause, probably
because the divider restarts counting whenever the register is rewritten.
This issue doesn't show up normally, because the clock framework will
take care to not call set_rate when the clock rate is the same.
However, when we reconfigure an upstream clock, the common code will
call set_rate with the newly calculated rate on all children, e.g.:
- sai5 is running normally and divides Audio PLL out by 16.
- Audio PLL rate is increased by 32Hz (glitch-free kdiv change)
- rates for children are recalculated and rates are set recursively
- imx8m_clk_composite_divider_set_rate(sai5) is called with
32/16 = 2Hz more
- imx8m_clk_composite_divider_set_rate computes same divider as before
- divider register is written, so it restarts counting from zero and
MCLK is briefly paused, so instead of e.g. 40ns, MCLK is low for 120ns.
Some external clock consumers can be upset by such unexpected clock pauses,
so let's make sure we only rewrite the divider value when the value to be
written is actually different.
