75500e7ba2 media: Revert "media: rkisp1: Drop IRQF_SHARED"
commit a107d643b2a3382e0a2d2c4ef08bf8c6bff4561d upstream.

This reverts commit 85d2a31fe4d9be1555f621ead7a520d8791e0f74.

The rkisp1 does share interrupt lines on some platforms, after all. Thus
we need to revert this, and implement a fix for the rkisp1 shared irq
handling in a follow-up patch.

bf808f5868 media: rkisp1: Fix IRQ disable race issue
[ Upstream commit 870565f063a58576e8a4529f122cac4325c6b395 ]

In rkisp1_isp_stop() and rkisp1_csi_disable() the driver masks the
interrupts and then apparently assumes that the interrupt handler won't
be running, and proceeds in the stop procedure. This is not the case, as
the interrupt handler can already be running, which would lead to the
ISP being disabled while the interrupt handler handling a captured
frame.

This brings up two issues: 1) the ISP could be powered off while the
interrupt handler is still running and accessing registers, leading to
board lockup, and 2) the interrupt handler code and the code that
disables the streaming might do things that conflict.

It is not clear to me if 2) causes a real issue, but 1) can be seen with
a suitable delay (or printk in my case) in the interrupt handler,
leading to board lockup.

[ Upstream commit 3eb7910e1b16a2c136be26a8380f21469225b2f6 ]

The IRQ handler rkisp1_isr() calls sub-handlers, all of which returns an
irqreturn_t value, but rkisp1_isr() ignores those values and always
returns IRQ_HANDLED.

Fix this by collecting the return values, and returning IRQ_HANDLED or
IRQ_NONE as appropriate.

[ Upstream commit 85d2a31fe4d9be1555f621ead7a520d8791e0f74 ]

In all known platforms the ISP has dedicated IRQ lines, but for some
reason the driver uses IRQF_SHARED.

Supporting IRQF_SHARED properly requires handling interrupts even when
our device is disabled, and the driver does not handle this. To avoid
adding such code, and to be sure the driver won't accidentally be used
in a platform with shared interrupts, let's drop the IRQF_SHARED flag.

[ Upstream commit 9e7dc39260edac180c206bb6149595a40eabae3e ]

When using 32 bit RGB formats, the RGA on the rk3568 produces wrong
colors as the wrong color channels are read or written.  The reason is
that the format description for the channel swizzeling is wrong and the
wrong bits are configured. For example, when converting ARGB32 to NV12,
the alpha channel is used as blue channel.. This doesn't happen if the
color format is the same on both sides.

Fix the color_swap settings of the formats to correctly handle 32 bit
RGB formats.

For RGA_COLOR_FMT_XBGR8888, the RGA_COLOR_ALPHA_SWAP bit doesn't have an
effect. Thus, it isn't possible to handle the V4L2_PIX_FMT_XRGB32. Thus,
it is removed from the list of supported formats.

9fec4db7ff media: mtk-jpeg: Fix use after free bug due to error path handling in mtk_jpeg_dec_device_run
commit 206c857dd17d4d026de85866f1b5f0969f2a109e upstream.

In mtk_jpeg_probe, &jpeg->job_timeout_work is bound with
mtk_jpeg_job_timeout_work.

In mtk_jpeg_dec_device_run, if error happens in
mtk_jpeg_set_dec_dst, it will finally start the worker while
mark the job as finished by invoking v4l2_m2m_job_finish.

There are two methods to trigger the bug. If we remove the
module, it which will call mtk_jpeg_remove to make cleanup.
The possible sequence is as follows, which will cause a
use-after-free bug.

CPU0                  CPU1
mtk_jpeg_dec_...    |
  start worker	    |
                    |mtk_jpeg_job_timeout_work
mtk_jpeg_remove     |
  v4l2_m2m_release  |
    kfree(m2m_dev); |
                    |
                    | v4l2_m2m_get_curr_priv
                    |   m2m_dev->curr_ctx //use

If we close the file descriptor, which will call mtk_jpeg_release,
it will have a similar sequence.

Fix this bug by starting timeout worker only if started jpegdec worker
successfully. Then v4l2_m2m_job_finish will only be called in
either mtk_jpeg_job_timeout_work or mtk_jpeg_dec_device_run.

[ Upstream commit 5d3c8990e2bbf929cb211563dadd70708f42e4e6 ]

The dma_q->p_left_data alloced by kzalloc should be freed in all the
following error handling paths. However, it hasn't been freed in the
allocation error paths of dev->video_mode.isoc_ctl.urb and
dev->video_mode.isoc_ctl.transfer_buffer.

On the other hand, the dma_q->p_left_data did be freed in the
error-handling paths after that of dev->video_mode.isoc_ctl.urb and
dev->video_mode.isoc_ctl.transfer_buffer, by calling
cx231xx_uninit_isoc(dev). So the same free operation should be done in
error-handling paths of those two allocation.

commit f910d3ba78a2677c23508f225eb047d89eb4b2b6 upstream.

Digging into the documentation we find that the DT_ID bitfield is used to
map the six bit DT to a two bit ID code. This value is concatenated to the
VC bitfield to create a CID value. DT_ID is the two least significant bits
of CID and VC the most significant bits.

Originally we set dt_id = vc * 4 in and then subsequently set dt_id = vc.

commit 3c4ed72a16bc ("media: camss: sm8250: Virtual channels for CSID")
silently fixed the multiplication by four which would give a better
value for the generated CID without mentioning what was being done or why.

Next up I haplessly changed the value back to "dt_id = vc * 4" since there
didn't appear to be any logic behind it.

Hans asked what the change was for and I honestly couldn't remember the
provenance of it, so I dug in.

[ Upstream commit 3c4ed72a16bc6733cda9c65048af74a2e8eaa0eb ]

CSID hardware on SM8250 can demux up to 4 simultaneous streams
based on virtual channel (vc) or datatype (dt).
The CSID subdevice entity now has 4 source ports that can be
enabled/disabled and thus can control which virtual channels
are enabled. Datatype demuxing not tested.

In order to keep a valid internal state of the subdevice,
implicit format propagation from the sink to the source pads
has been preserved. However, the format on each source pad
can be different and in that case it must be configured explicitly.

CSID's s_stream is called when any stream is started or stopped.
It will call configure_streams() that will rewrite IRQ settings to HW.
When multiple streams are running simultaneously there is an issue
when writing IRQ settings for one stream while another is still
running, thus avoid re-writing settings if they were not changed
in link setup, or by fully powering off the CSID hardware.

[ Upstream commit 428bbf4be4018aefa26e4d6531779fa8925ecaaf ]

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

4ae3c85e73 media: camss: Split power domain management
[ Upstream commit 46cc031754985ee24034d55687540adb079f8630 ]

There are three cases of power domain management on supported platforms:
1) CAMSS on MSM8916, where a single VFE power domain is operated outside
   of the camss device driver,
2) CAMSS on MSM8996 and SDM630/SDM660, where two VFE power domains are
   managed separately by the camss device driver, the power domains are
   linked and unlinked on demand by their functions vfe_pm_domain_on()
   and vfe_pm_domain_off() respectively,
3) CAMSS on SDM845 and SM8250 platforms, and there are two VFE power
   domains and their parent power domain TITAN_TOP, the latter one
   shall be turned on prior to turning on any of VFE power domains.

Due to a previously missing link between TITAN_TOP and VFEx power domains
in the latter case, which is now fixed by [1], it was decided always to
turn on all found VFE power domains and TITAN_TOP power domain, even if
just one particular VFE is needed to be enabled or none of VFE power
domains are required, for instance the latter case is when vfe_lite is in
use. This misusage becomes more incovenient and clumsy, if next generations
are to be supported, for instance CAMSS on SM8450 has three VFE power
domains.

The change splits the power management support for platforms with TITAN_TOP
parent power domain, and, since 'power-domain-names' property is not
present in camss device tree nodes, the assumption is that the first
N power domains from the 'power-domains' list correspond to VFE power
domains, and, if the number of power domains is greater than number of
non-lite VFEs, then the last power domain from the list is the TITAN_TOP
power domain.

commit 87889f1b7ea40d2544b49c62092e6ef2792dced7 upstream.

In the current driver csid Test Pattern Generator (TPG) doesn't work.
This change:
- fixes writing frame width and height values into CSID_TPG_DT_n_CFG_0
- fixes the shift by one between test_pattern control value and the
  actual pattern.
- drops fixed VC of 0x0a which testing showed prohibited some test
  patterns in the CSID to produce output.
So that TPG starts working, but with the below limitations:
- only test_pattern=9 works as it should
- test_pattern=8 and test_pattern=7 produce black frame (all zeroes)
- the rest of test_pattern's don't work (yavta doesn't get the data)
- regardless of the CFA pattern set by 'media-ctl -V' the actual pixel
  order is always the same (RGGB for any RAW8 or RAW10P format in
  4608x2592 resolution).

Tested with:

RAW10P format, VC0:

commit 3143ad282fc08bf995ee73e32a9e40c527bf265d upstream.

There are two problems with the current vfe_disable_output() routine.

Firstly we rightly use a spinlock to protect output->gen2.active_num
everywhere except for in the IDLE timeout path of vfe_disable_output().
Even if that is not racy "in practice" somehow it is by happenstance not
by design.

Secondly we do not get consistent behaviour from this routine. On
sc8280xp 50% of the time I get "VFE idle timeout - resetting". In this
case the subsequent capture will succeed. The other 50% of the time, we
don't hit the idle timeout, never do the VFE reset and subsequent
captures stall indefinitely.

Rewrite the vfe_disable_output() routine to

- Quiesce write masters with vfe_wm_stop()
- Set active_num = 0

remembering to hold the spinlock when we do so followed by

- Reset the VFE

Testing on sc8280xp and sdm845 shows this to be a valid fix.

commit 26bda3da00c3edef727a6acb00ed2eb4b22f8723 upstream.

Right now it is possible to do a vfe_get() with the internal reference
count at 1. If vfe_check_clock_rates() returns non-zero then we will
leave the reference count as-is and

run:
- pm_runtime_put_sync()
- vfe->ops->pm_domain_off()

skip:
- camss_disable_clocks()

Subsequent vfe_put() calls will when the ref-count is non-zero
unconditionally run:

- pm_runtime_put_sync()
- vfe->ops->pm_domain_off()
- camss_disable_clocks()

vfe_get() should not attempt to roll-back on error when the ref-count is
non-zero as the upper layers will still do their own vfe_put() operations.

vfe_put() will drop the reference count and do the necessary power
domain release, the cleanup jumps in vfe_get() should only be run when
the ref-count is zero.

commit 7405116519ad70b8c7340359bfac8db8279e7ce4 upstream.

We need to make sure camss_configure_pd() happens before
camss_register_entities() as the vfe_get() path relies on the pointer
provided by camss_configure_pd().

Fix the ordering sequence in probe to ensure the pointers vfe_get() demands
are present by the time camss_register_entities() runs.

In order to facilitate backporting to stable kernels I've moved the
configure_pd() call pretty early on the probe() function so that
irrespective of the existence of the old error handling jump labels this
patch should still apply to -next circa Aug 2023 to v5.13 inclusive.

Initialise the try sink compose rectangle size to the sink compose

faulty condition that lead to the compose rectangles to be initialised for
the pixel array sub-device where it is not relevant.

commit 8d0b89398b7ebc52103e055bf36b60b045f5258f upstream.

The hfi parser, parses the capabilities received from venus firmware and
copies them to core capabilities. Consider below api, for example,
fill_caps - In this api, caps in core structure gets updated with the
number of capabilities received in firmware data payload. If the same api
is called multiple times, there is a possibility of copying beyond the max
allocated size in core caps.
Similar possibilities in fill_raw_fmts and fill_profile_level functions.

commit 0768a9dd809ef52440b5df7dce5a1c1c7e97abbd upstream.

Supported codec bitmask is populated from the payload from venus firmware.
There is a possible case when all the bits in the codec bitmask is set. In
such case, core cap for decoder is filled  and MAX_CODEC_NUM is utilized.
Now while filling the caps for encoder, it can lead to access the caps
array beyong 32 index. Hence leading to OOB write.
The fix counts the supported encoder and decoder. If the count is more than
max, then it skips accessing the caps.

b083aaf5db media: imon: fix access to invalid resource for the second interface
[ Upstream commit a1766a4fd83befa0b34d932d532e7ebb7fab1fa7 ]

imon driver probes two USB interfaces, and at the probe of the second
interface, the driver assumes blindly that the first interface got
bound with the same imon driver.  It's usually true, but it's still
possible that the first interface is bound with another driver via a
malformed descriptor.  Then it may lead to a memory corruption, as
spotted by syzkaller; imon driver accesses the data from drvdata as
struct imon_context object although it's a completely different one
that was assigned by another driver.

This patch adds a sanity check -- whether the first interface is
really bound with the imon driver or not -- for avoiding the problem
above at the probe time.
