The current rule for generating signing_key.priv and signing_key.x509 is
a classic example of a bad rule which has a tendency to break parallel
make. When invoked to create *either* target, it generates the other
target as a side-effect that make didn't predict.
So let's switch to using a single file signing_key.pem which contains
both key and certificate. That matches what we do in the case of an
external key specified by CONFIG_MODULE_SIG_KEY anyway, so it's also
slightly cleaner.

Move to using PKCS#7 messages as module signatures because:
(1) We have to be able to support the use of X.509 certificates that don't
have a subjKeyId set. We're currently relying on this to look up the
X.509 certificate in the trusted keyring list.
(2) PKCS#7 message signed information blocks have a field that supplies the
data required to match with the X.509 certificate that signed it.
(3) The PKCS#7 certificate carries fields that specify the digest algorithm
used to generate the signature in a standardised way and the X.509
certificates specify the public key algorithm in a standardised way - so
we don't need our own methods of specifying these.
(4) We now have PKCS#7 message support in the kernel for signed kexec purposes
and we can make use of this.
To make this work, the old sign-file script has been replaced with a program
that needs compiling in a previous patch. The rules to build it are added
here.

Provide a utility that:
(1) Digests a module using the specified hash algorithm (typically sha256).
[The digest can be dumped into a file by passing the '-d' flag]
(2) Generates a PKCS#7 message that:
(a) Has detached data (ie. the module content).
(b) Is signed with the specified private key.
(c) Refers to the specified X.509 certificate.
(d) Has an empty X.509 certificate list.
[The PKCS#7 message can be dumped into a file by passing the '-p' flag]
(3) Generates a signed module by concatenating the old module, the PKCS#7
message, a descriptor and a magic string. The descriptor contains the
size of the PKCS#7 message and indicates the id_type as PKEY_ID_PKCS7.
(4) Either writes the signed module to the specified destination or renames
it over the source module.
This allows module signing to reuse the PKCS#7 handling code that was added
for PE file parsing for signed kexec.
Note that the utility is written in C and must be linked against the OpenSSL
crypto library.
Note further that I have temporarily dropped support for handling externally
created signatures until we can work out the best way to do those. Hopefully,
whoever creates the signature can give me a PKCS#7 certificate.

It is possible for a PKCS#7 message to have detached data. However, to verify
the signatures on a PKCS#7 message, we have to be able to digest the data.
Provide a function to supply that data. An error is given if the PKCS#7
message included embedded data.
This is used in a subsequent patch to supply the data to module signing where
the signature is in the form of a PKCS#7 message with detached data, whereby
the detached data is the module content that is signed.

If an X.509 certificate has an AuthorityKeyIdentifier extension that provides
an issuer and serialNumber, then make it so that these are used in preference
to the keyIdentifier field also held therein for searching for the signing
certificate.
If both the issuer+serialNumber and the keyIdentifier are supplied, then the
certificate is looked up by the former but the latter is checked as well. If
the latter doesn't match the subjectKeyIdentifier of the parent certificate,
EKEYREJECTED is returned.
This makes it possible to chain X.509 certificates based on the issuer and
serialNumber fields rather than on subjectKeyIdentifier. This is necessary as
we are having to deal with keys that are represented by X.509 certificates
that lack a subjectKeyIdentifier.

Since llvm__compile_bpf() prints long messages which users who don't

suppress all debug, warning and error message, and hint user use 'perf

Lockdep validator complains about recursive locking and deadlock
when two different regmap instances are called in a nested order.
That happens anytime a regmap read/write call needs to access
another regmap.
This is because, for performance reason, lockdep groups all locks
initialized by the same mutex_init() in the same lock class.
Therefore all regmap mutexes are in the same lock class, leading
to lockdep "nested locking" warnings if a regmap accesses another
regmap.
In general, it is impossible to establish in advance the hierarchy
of regmaps, so we make sure that each regmap init call initializes
its own static lock_class_key. This is done by wrapping all
regmap_init calls into macros.
This also allows us to give meaningful names to the lock_class_key.
For example, in rt5677 case, we have in /proc/lockdep_chains:
irq_context: 0
[ffffffc0018d2198] &dev->mutex
[ffffffc0018d2198] &dev->mutex
[ffffffc001bd7f60] rt5677:5104:(&rt5677_regmap)->_lock
[ffffffc001bd7f58] rt5677:5096:(&rt5677_regmap_physical)->_lock
[ffffffc001b95448] &(&base->lock)->rlock
The above would have resulted in a lockdep recursive warning
previously. This is not the case anymore as the lockdep validator
now clearly identifies the 2 regmaps as separate.
