This release, we add support for inline encryption via the blk-crypto
framework which was added in 5.8. Now when an ext4 or f2fs filesystem
is mounted with '-o inlinecrypt', the contents of encrypted files will
be encrypted/decrypted via blk-crypto, instead of directly using the
crypto API. This model allows taking advantage of the inline encryption
hardware that is integrated into the UFS or eMMC host controllers on
most mobile SoCs. Note that this is just an alternate implementation;
the ciphertext written to disk stays the same.
(This pull request does *not* include support for direct I/O on
encrypted files, which blk-crypto makes possible, since that part is
still being discussed.)
Besides the above feature update, there are also a few fixes and
cleanups, e.g. strengthening some memory barriers that may be too weak.
All these patches have been in linux-next with no reported issues. I've
also tested them with the fscrypt xfstests, as usual. It's also been
tested that the inline encryption support works with the support for
Qualcomm and Mediatek inline encryption hardware that will be in the
scsi pull request for 5.9. Also, several SoC vendors are already using
a previous, functionally equivalent version of these patches.

"xxx``at``" makes the `` appear verbatim in the HTML output. I've opted
for changing this into ``*at()`` to harmonise this with the use of * seen
later in the same document (and add the parentheses to clarify that this
is a system/function call).
``path_``* also makes `` appear in the HTML output, but we can fix it by

The UDP reuseport conflict was a little bit tricky.
The net-next code, via bpf-next, extracted the reuseport handling
into a helper so that the BPF sk lookup code could invoke it.
At the same time, the logic for reuseport handling of unconnected
sockets changed via commit efc6b6f6c3
which changed the logic to carry on the reuseport result into the
rest of the lookup loop if we do not return immediately.
This requires moving the reuseport_has_conns() logic into the callers.
While we are here, get rid of inline directives as they do not belong
in foo.c files.
The other changes were cases of more straightforward overlapping
modifications.

The name "FS_KEY_DERIVATION_NONCE_SIZE" is a bit outdated since due to
the addition of FSCRYPT_POLICY_FLAG_DIRECT_KEY, the file nonce may now
be used as a tweak instead of for key derivation. Also, we're now
prefixing the fscrypt constants with "FSCRYPT_" instead of "FS_".
Therefore, rename this constant to FSCRYPT_FILE_NONCE_SIZE.

debugfs_create_u32_array() allocates a small structure to wrap
the data and size information about the array. If users ever
try to remove the file this leads to a leak since nothing ever
frees this wrapper.
That said there are no upstream users of debugfs_create_u32_array()
that'd remove a u32 array file (we only have one u32 array user in
CMA), so there is no real bug here.
Make callers pass a wrapper they allocated. This way the lifetime
management of the wrapper is on the caller, and we can avoid the
potential leak in debugfs.

Wire up f2fs to support inline encryption via the helper functions which
fs/crypto/ now provides. This includes:
- Adding a mount option 'inlinecrypt' which enables inline encryption
on encrypted files where it can be used.
- Setting the bio_crypt_ctx on bios that will be submitted to an
inline-encrypted file.
- Not adding logically discontiguous data to bios that will be submitted
to an inline-encrypted file.
- Not doing filesystem-layer crypto on inline-encrypted files.

Add support for inline encryption to fs/crypto/. With "inline
encryption", the block layer handles the decryption/encryption as part
of the bio, instead of the filesystem doing the crypto itself via
Linux's crypto API. This model is needed in order to take advantage of
the inline encryption hardware present on most modern mobile SoCs.
To use inline encryption, the filesystem needs to be mounted with
'-o inlinecrypt'. Blk-crypto will then be used instead of the traditional
filesystem-layer crypto whenever possible to encrypt the contents
of any encrypted files in that filesystem. Fscrypt still provides the key
and IV to use, and the actual ciphertext on-disk is still the same;
therefore it's testable using the existing fscrypt ciphertext verification
tests.
Note that since blk-crypto has a fallback to Linux's crypto API, and
also supports all the encryption modes currently supported by fscrypt,
this feature is usable and testable even without actual inline
encryption hardware.
Per-filesystem changes will be needed to set encryption contexts when
submitting bios and to implement the 'inlinecrypt' mount option. This
patch just adds the common code.

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.
Deterministic algorithm:
For each file:
If not .svg:
For each line:
If doesn't contain `\bxmlns\b`:
For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
If both the HTTP and HTTPS versions
return 200 OK and serve the same content:
Replace HTTP with HTTPS.

Commit ed318a6cc0 ("fscrypt: support test_dummy_encryption=v2") added an
entry to the massive option table in Documentation/filesystems/f2fs.txt.
The option was too wide for the formatting of the table, though, leading to
a verbose and ugly warning starting with:
Documentation/filesystems/f2fs.rst:229: WARNING: Malformed table.
Text in column margin in table line 126.
Fixing this requires formatting the whole table; let's hear it for Emacs

In this round, we've added some knobs to enhance compression feature and harden
testing environment. In addition, we've fixed several bugs reported from Android
devices such as long discarding latency, device hanging during quota_sync, etc.
Enhancement:
- support lzo-rle algorithm
- add two ioctls to release and reserve blocks for compression
- support partial truncation/fiemap on compressed file
- introduce sysfs entries to attach IO flags explicitly
- add iostat trace point along with read io stat
Bug fix:
- fix long discard latency
- flush quota data by f2fs_quota_sync correctly
- fix to recover parent inode number for power-cut recovery
- fix lz4/zstd output buffer budget
- parse checkpoint mount option correctly
- avoid inifinite loop to wait for flushing node/meta pages
- manage discard space correctly
And some refactoring and clean up patches were added.
