Trusted keys unseal the key blob on load, but keep the sealed payload in
the blob field so that every subsequent read (export) will simply
convert this field to hex and send it to userspace.
With DCP-based trusted keys, we decrypt the blob encryption key (BEK)
in the Kernel due hardware limitations and then decrypt the blob payload.
BEK decryption is done in-place which means that the trusted key blob
field is modified and it consequently holds the BEK in plain text.
Every subsequent read of that key thus send the plain text BEK instead
of the encrypted BEK to userspace.
This issue only occurs when importing a trusted DCP-based key and
then exporting it again. This should rarely happen as the common use cases
are to either create a new trusted key and export it, or import a key
blob and then just use it without exporting it again.
Fix this by performing BEK decryption and encryption in a dedicated
buffer. Further always wipe the plain text BEK buffer to prevent leaking
the key via uninitialized memory.

__btrfs_add_free_space_zoned() references and modifies bg's alloc_offset,
ro, and zone_unusable, but without taking the lock. It is mostly safe
because they monotonically increase (at least for now) and this function is
mostly called by a transaction commit, which is serialized by itself.
Still, taking the lock is a safer and correct option and I'm going to add a
change to reset zone_unusable while a block group is still alive. So, add
locking around the operations.

[REPORT]
There is a corruption report that btrfs refused to mount a fs that has
overlapping dev extents:
BTRFS error (device sdc): dev extent devid 4 physical offset 14263979671552 overlap with previous dev extent end 14263980982272
BTRFS error (device sdc): failed to verify dev extents against chunks: -117
BTRFS error (device sdc): open_ctree failed
[CAUSE]
The direct cause is very obvious, there is a bad dev extent item with
incorrect length.
With btrfs check reporting two overlapping extents, the second one shows
some clue on the cause:
ERROR: dev extent devid 4 offset 14263979671552 len 6488064 overlap with previous dev extent end 14263980982272
ERROR: dev extent devid 13 offset 2257707008000 len 6488064 overlap with previous dev extent end 2257707270144
ERROR: errors found in extent allocation tree or chunk allocation
The second one looks like a bitflip happened during new chunk
allocation:
hex(2257707008000) = 0x20da9d30000
hex(2257707270144) = 0x20da9d70000
diff = 0x00000040000
So it looks like a bitflip happened during new dev extent allocation,
resulting the second overlap.
Currently we only do the dev-extent verification at mount time, but if the
corruption is caused by memory bitflip, we really want to catch it before
writing the corruption to the storage.
Furthermore the dev extent items has the following key definition:
(<device id> DEV_EXTENT <physical offset>)
Thus we can not just rely on the generic key order check to make sure
there is no overlapping.
[ENHANCEMENT]
Introduce dedicated dev extent checks, including:
- Fixed member checks
* chunk_tree should always be BTRFS_CHUNK_TREE_OBJECTID (3)
* chunk_objectid should always be
BTRFS_FIRST_CHUNK_CHUNK_TREE_OBJECTID (256)
- Alignment checks
* chunk_offset should be aligned to sectorsize
* length should be aligned to sectorsize
* key.offset should be aligned to sectorsize
- Overlap checks
If the previous key is also a dev-extent item, with the same
device id, make sure we do not overlap with the previous dev extent.

EDID cannot be read on RK3328 until after read_hpd has been called and
correct io voltage has been configured based on connection status.
When a forced mode is used, e.g. video=1920x1080@60e, the connector
detect ops, that in turn normally calls the read_hpd, never gets called.
This result in reading EDID to fail in connector get_modes ops.

-ENODEV is used to signify that there is no zap shader for the platform,
and the CPU can directly take the GPU out of secure mode. We want to
use this return code when there is no zap-shader node. But not when
there is, but without a firmware-name property. This case we want to
treat as-if the needed fw is not found.

- Revert a recent change to sense data generation.
Sense data can be in either fixed format or descriptor format.
The D_SENSE bit in the Control mode page controls which format to
generate. All places but one respected the D_SENSE bit.
The recent change fixed the one place that didn't respect the D_SENSE
bit. However, it turns out that hdparm, hddtemp and udisks
(incorrectly) assumes sense data in descriptor format.
Therefore, even while the change was technically correct, revert it,
since even if these user space programs are fixed to (correctly) look
at the format type before parsing the data, older versions of these
tools will be around roughly forever.

hci_conn_params_add() never checks for a NULL value and could lead to a NULL
pointer dereference causing a crash.
Fixed by adding error handling in the function.

This inverts the LE State quirk so by default we assume the controllers
would report valid states rather than invalid which is how quirks
normally behave, also this would result in HCI command failing it the LE
States are really broken thus exposing the controllers that are really
broken in this respect.

The device contains two i2c-connected eeproms holding some product-
specific values. One sitting on the mainboard and one on the statically
connected backplane.
While the eeprom chips themself have a size of 512 byte, the eeprom data
only uses 256 byte each, probably to stay compatible with other models.

With CONFIG_LTO_CLANG=y, the compiler may add .llvm.<hash> suffix to
function names to avoid duplication. APIs like kallsyms_lookup_name()
and kallsyms_on_each_match_symbol() tries to match these symbol names
without the .llvm.<hash> suffix, e.g., match "c_stop" with symbol
c_stop.llvm.17132674095431275852. This turned out to be problematic
for use cases that require exact match, for example, livepatch.
Fix this by making the APIs to match symbols exactly.
Also cleanup kallsyms_selftests accordingly.

When @size is 0, the desired behavior is to allow unlimited bytes to be
parsed. Currently, this relies on some intentional arithmetic overflow
where --size gives us SIZE_MAX when size is 0.
Explicitly spell out the desired behavior without relying on intentional
overflow/underflow.
