[ Upstream commit 040b5a046a9e18098580d3ccd029e2318fca7859 ]
Two functions are defined and used in pcm_oss.c but also optionally
used from io.c, with an optional prototype. If CONFIG_SND_PCM_OSS_PLUGINS
is disabled, this causes a warning as the functions are not static
and have no prototype:
sound/core/oss/pcm_oss.c:1235:19: error: no previous prototype for 'snd_pcm_oss_write3' [-Werror=missing-prototypes]
sound/core/oss/pcm_oss.c:1266:19: error: no previous prototype for 'snd_pcm_oss_read3' [-Werror=missing-prototypes]
Avoid this by making the prototypes unconditional.

clang warns about an unpacked structure inside of a packed one:
drivers/net/wireless/broadcom/b43/b43.h:654:4: error: field data within 'struct b43_iv' is less aligned than 'union (unnamed union at /home/arnd/arm-soc/drivers/net/wireless/broadcom/b43/b43.h:651:2)' and is usually due to 'struct b43_iv' being packed, which can lead to unaligned accesses [-Werror,-Wunaligned-access]
The problem here is that the anonymous union has the default alignment
from its members, apparently because the original author mixed up the
placement of the __packed attribute by placing it next to the struct
member rather than the union definition. As the struct itself is
also marked as __packed, there is no need to mark its members, so just
move the annotation to the inner type instead.
As Michael noted, the same problem is present in b43legacy, so
change both at the same time.

If scsi_dispatch_cmd() failed, the SCSI command was not sent to the target,
scsi_queue_rq() would return BLK_STS_RESOURCE and the related request would
be requeued. The timeout of this request would not fire, no one would
increase iodone_cnt.
The above flow would result the iodone_cnt smaller than iorequest_cnt. So
decrease the iorequest_cnt if dispatch failed to workaround the issue.

If the device node of dvb_ca_en50221 is open() and the
device is disconnected, a UAF may occur when calling
close() on the device node.
The root cause is that wake_up() and wait_event() for
dvbdev->wait_queue are not implemented.
So implement wait_event() function in dvb_ca_en50221_release()
and add 'remove_mutex' which prevents race condition
for 'ca->exit'.

Using a semaphore in the wait_event*() condition is no good idea.
It hits a kernel WARN_ON() at prepare_to_wait_event() like:
do not call blocking ops when !TASK_RUNNING; state=1 set at
prepare_to_wait_event+0x6d/0x690
For avoiding the potential deadlock, rewrite to an open-coded loop
instead. Unlike the loop in wait_event*(), this uses wait_woken()
after the condition check, hence the task state stays consistent.

[ Upstream commit 627bb528b086b4136315c25d6a447a98ea9448d3 ]
dvb_register_device() dynamically allocates fops with kmemdup()
to set the fops->owner.
And these fops are registered in 'file->f_ops' using replace_fops()
in the dvb_device_open() process, and kfree()d in dvb_free_device().
However, it is not common to use dynamically allocated fops instead
of 'static const' fops as an argument of replace_fops(),
and UAF may occur.
These UAFs can occur on any dvb type using dvb_register_device(),
such as dvb_dvr, dvb_demux, dvb_frontend, dvb_net, etc.
So, instead of kfree() the fops dynamically allocated in
dvb_register_device() in dvb_free_device() called during the
.disconnect() process, kfree() it collectively in exit_dvbdev()
called when the dvbdev.c module is removed.

A race condition may occur between the .disconnect function, which
is called when the device is disconnected, and the dvb_device_open()
function, which is called when the device node is open()ed.
This results in several types of UAFs.
The root cause of this is that you use the dvb_device_open() function,
which does not implement a conditional statement
that checks 'dvbnet->exit'.
So, add 'remove_mutex` to protect 'dvbnet->exit' and use
locked_dvb_net_open() function to check 'dvbnet->exit'.

The function of "dvb_ca_en50221_write_data" at source/drivers/media
/dvb-core/dvb_ca_en50221.c is used for two cases.
The first case is for writing APDU data in the function of
"dvb_ca_en50221_io_write" at source/drivers/media/dvb-core/
dvb_ca_en50221.c.
The second case is for writing the host link buf size on the
Command Register in the function of "dvb_ca_en50221_link_init"
at source/drivers/media/dvb-core/dvb_ca_en50221.c.
In the second case, there exists a bug like following.
In the function of the "dvb_ca_en50221_link_init",
after a TV host calculates the host link buf_size,
the TV host writes the calculated host link buf_size on the
Size Register.
Accroding to the en50221 Spec (the page 60 of
https://dvb.org/wp-content/uploads/2020/02/En50221.V1.pdf),
before this writing operation, the "SW(CMDREG_SW)" flag in the
Command Register should be set. We can see this setting operation
in the function of the "dvb_ca_en50221_link_init" like below.
...
if ((ret = ca->pub->write_cam_control(ca->pub, slot,
CTRLIF_COMMAND, IRQEN | CMDREG_SW)) != 0)
return ret;
...
But, after that, the real writing operation is implemented using
the function of the "dvb_ca_en50221_write_data" in the function of
"dvb_ca_en50221_link_init", and the "dvb_ca_en50221_write_data"
includes the function of "ca->pub->write_cam_control",
and the function of the "ca->pub->write_cam_control" in the
function of the "dvb_ca_en50221_wrte_data" does not include
"CMDREG_SW" flag like below.
...
if ((status = ca->pub->write_cam_control(ca->pub, slot,
CTRLIF_COMMAND, IRQEN | CMDREG_HC)) != 0)
...
In the above source code, we can see only the "IRQEN | CMDREG_HC",
but we cannot see the "CMDREG_SW".
The "CMDREG_SW" flag which was set in the function of the
"dvb_ca_en50221_link_init" was rollbacked by the follwoing function
of the "dvb_ca_en50221_write_data".
This is a bug. and this bug causes that the calculated host link buf_size
is not properly written in the CI module.
Through this patch, we fix this bug.

[ Upstream commit f63550e2b165208a2f382afcaf5551df9569e1d4 ]
Apply a workaround for what appears to be a hardware quirk.
The problem seems to happen when enabling "whole chip power" (bit D7
register R6) for the very first time after the chip receives power. If
either "output" (D4) or "DAC" (D3) aren't powered on at that time,
playback becomes very distorted later on.
This happens on the Google Chameleon v3, as well as on a ZYBO Z7-10:
https://ez.analog.com/audio/f/q-a/543726/solved-ssm2603-right-output-offset-issue/480229
I suspect this happens only when using an external MCLK signal (which
is the case for both of these boards).
Here are some experiments run on a Google Chameleon v3. These were run
in userspace using a wrapper around the i2cset utility:
ssmset() {
i2cset -y 0 0x1a $(($1*2)) $2
}
For each of the following sequences, we apply power to the ssm2603
chip, set the configuration registers R0-R5 and R7-R8, run the selected
sequence, and check for distortions on playback.
ssmset 0x09 0x01 # core
ssmset 0x06 0x07 # chip, out, dac
OK
ssmset 0x09 0x01 # core
ssmset 0x06 0x87 # out, dac
ssmset 0x06 0x07 # chip

(disable MCLK)
ssmset 0x09 0x01 # core
ssmset 0x06 0x1f # chip

(enable MCLK)

NOT OK
ssmset 0x09 0x01 # core
ssmset 0x06 0x17 # chip, dac
ssmset 0x06 0x07 # out

For each of the following sequences, we apply power to the ssm2603
chip, run the selected sequence, issue a reset with R15, configure
R0-R5 and R7-R8, run one of the NOT OK sequences from above, and check
for distortions.

This change ensures that if configured in the policy, the if_id set in
the policy and secpath states match during the inbound policy check.
Without this, there is potential for ambiguity where entries in the
secpath differing by only the if_id could be mismatched.
Notably, this is checked in the outbound direction when resolving
templates to SAs, but not on the inbound path when matching SAs and
policies.

[ Upstream commit 504a10d9e46bc37b23d0a1ae2f28973c8516e636 ]
On corrupt gfs2 file systems the evict code can try to reference the
journal descriptor structure, jdesc, after it has been freed and set to
NULL. The sequence of events is:
init_journal()
...
fail_jindex:
gfs2_jindex_free(sdp); <------frees journals, sets jdesc = NULL
if (gfs2_holder_initialized(&ji_gh))
gfs2_glock_dq_uninit(&ji_gh);
fail:
iput(sdp->sd_jindex); <--references jdesc in evict_linked_inode
evict()
gfs2_evict_inode()
evict_linked_inode()
ret = gfs2_trans_begin(sdp, 0, sdp->sd_jdesc->jd_blocks);
<------references the now freed/zeroed sd_jdesc pointer.
The call to gfs2_trans_begin is done because the truncate_inode_pages
call can cause gfs2 events that require a transaction, such as removing
journaled data (jdata) blocks from the journal.
This patch fixes the problem by adding a check for sdp->sd_jdesc to
function gfs2_evict_inode. In theory, this should only happen to corrupt
gfs2 file systems, when gfs2 detects the problem, reports it, then tries
to evict all the system inodes it has read in up to that point.

When adding proper support for V4L2_FIELD_ALTERNATE it was missed that
this field format should trigger an interrupt for each field, not just
for the whole frame. Fix this by marking it as progressive in the
capture setup, which will then select the correct interrupt mode.
Tested on both Gen2 and Gen3 with the result of a doubling of the frame
rate for V4L2_FIELD_ALTERNATE. From a PAL video source the frame rate is
now 50, which is expected for alternate field capture.

When unwind instruction is 0xb2,the subsequent instructions
are uleb128 bytes.
For now,it uses only the first uleb128 byte in code.
For vsp increments of 0x204~0x400,use one uleb128 byte like below:
0xc06a00e4 <unwind_test_work>: 0x80b27fac
Compact model index: 0
0xb2 0x7f vsp = vsp + 1024
0xac pop {r4, r5, r6, r7, r8, r14}
For vsp increments larger than 0x400,use two uleb128 bytes like below:
0xc06a00e4 <unwind_test_work>: @0xc0cc9e0c
Compact model index: 1
0xb2 0x81 0x01 vsp = vsp + 1032
0xac pop {r4, r5, r6, r7, r8, r14}
The unwind works well since the decoded uleb128 byte is also 0x81.
For vsp increments larger than 0x600,use two uleb128 bytes like below:
0xc06a00e4 <unwind_test_work>: @0xc0cc9e0c
Compact model index: 1
0xb2 0x81 0x02 vsp = vsp + 1544
0xac pop {r4, r5, r6, r7, r8, r14}
In this case,the decoded uleb128 result is 0x101(vsp=0x204+(0x101<<2)).
While the uleb128 used in code is 0x81(vsp=0x204+(0x81<<2)).
The unwind aborts at this frame since it gets incorrect vsp.
To fix this,add uleb128 decode to cover all the above case.

If the sibling keys check fails before we move keys from one sibling
leaf to another, we are not aborting the transaction - we leave that to
some higher level caller of btrfs_search_slot() (or anything else that
uses it to insert items into a b+tree).
This means that the transaction abort will provide a stack trace that
omits the b+tree modification call chain. So change this to immediately
abort the transaction and therefore get a more useful stack trace that
shows us the call chain in the bt+tree modification code.
It's also important to immediately abort the transaction just in case
some higher level caller is not doing it, as this indicates a very
serious corruption and we should stop the possibility of doing further
damage.
