Subject: crypto: cryptd - Fix AEAD request context corruption

The AEAD version of cryptd uses the same context for its own state
as well as that of the child.  In doing so it did not maintain the
proper ordering, thus resulting in potential state corruption where
the child will overwrite the state stored by cryptd.

This patch fixes and also sets the request size properly.

Subject: crypto: api - Add instance free function to crypto_type

Currently the task of freeing an instance is given to the crypto
template.  However, it has no type information on the instance so
we have to resort to checking type information at runtime.

This patch introduces a free function to crypto_type that will be
used to free an instance.  This can then be used to free an instance
in a type-safe manner.

Subject: crypto: echainiv - Fix encryption convention

This patch fixes a bug where we were incorrectly including the
IV in the AD during encryption.  The IV must remain in the plain
text for it to be encrypted.

During decryption there is no need to copy the IV to dst because
it's now part of the AD.

This patch removes an unncessary check on authsize which would be
performed by the underlying decrypt call.

Finally this patch makes use of the type-safe init/exit functions.

Subject: crypto: seqiv - Replace seqniv with seqiv

This patch replaces the seqniv generator with seqiv when the
underlying algorithm understands the new calling convention.

This not only makes more sense as now seqiv is solely responsible
for IV generation rather than also determining how the IV is going
to be used, it also allows for optimisations in the underlying
implementation.  For example, the space for the IV could be used
to add padding for authentication.

This patch also removes the unnecessary copying of IV to dst
during seqiv decryption as the IV is part of the AD and not cipher
text.

Subject: crypto: gcm - Use new IV convention

This patch converts rfc4106 to the new calling convention where
the IV is now part of the AD and needs to be skipped.  This patch
also makes use of the new type-safe way of freeing instances.

This patch disables the rfc4309 test while the conversion to the
new seqiv calling convention takes place.  It also replaces the
rfc4309 test vectors with ones that will work with the new IV
convention.

Subject: crypto: tcrypt - Add ChaCha20/Poly1305 speed tests

Adds individual ChaCha20 and Poly1305 and a combined rfc7539esp AEAD speed
test using mode numbers 214, 321 and 213. For Poly1305 we add a specific
speed template, as it expects the key prepended to the input data.

Subject: crypto: chacha20 - Add a SSSE3 SIMD variant for x86_64

Implements an x86_64 assembler driver for the ChaCha20 stream cipher. This
single block variant works on a single state matrix using SSE instructions.
It requires SSSE3 due the use of pshufb for efficient 8/16-bit rotate
operations.

For large messages, throughput increases by ~65% compared to
chacha20-generic:

Subject: crypto: chacha20 - Add an eight block AVX2 variant for x86_64

Extends the x86_64 ChaCha20 implementation by a function processing eight
ChaCha20 blocks in parallel using AVX2.

For large messages, throughput increases by ~55-70% compared to four block
SSSE3:

Subject: crypto: testmgr - Add a longer ChaCha20 test vector

The AVX2 variant of ChaCha20 is used only for messages with >= 512 bytes
length. With the existing test vectors, the implementation could not be
tested. Due that lack of such a long official test vector, this one is
self-generated using chacha20-generic.

Subject: crypto: poly1305 - Add a SSE2 SIMD variant for x86_64

Implements an x86_64 assembler driver for the Poly1305 authenticator. This
single block variant holds the 130-bit integer in 5 32-bit words, but uses
SSE to do two multiplications/additions in parallel.

When calling updates with small blocks, the overhead for kernel_fpu_begin/
kernel_fpu_end() negates the perfmance gain. We therefore use the
poly1305-generic fallback for small updates.

For large messages, throughput increases by ~5-10% compared to
poly1305-generic:

Subject: crypto: poly1305 - Add a four block AVX2 variant for x86_64

Extends the x86_64 Poly1305 authenticator by a function processing four
consecutive Poly1305 blocks in parallel using AVX2 instructions.

For large messages, throughput increases by ~15-45% compared to two
block SSE2:

Since the API for jent_panic() does not include format string parameters,
adjust the call to panic() to use a literal string to avoid any future

From 73e55e8c4c4a2635c5630733beffe872177511a5 Mon Sep 17 00:00:00 2001
From: David Howells <dhowells@redhat.com>

Subject: X.509: Extract both parts of the AuthorityKeyIdentifier

Extract both parts of the AuthorityKeyIdentifier, not just the keyIdentifier,
as the second part can be used to match X.509 certificates by issuer and
serialNumber.

Subject: X.509: Support X.509 lookup by Issuer+Serial form
 AuthorityKeyIdentifier

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.

Subject: PKCS#7: Allow detached data to be supplied for signature checking
 purposes

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.

Subject: PKCS#7: Check content type and versions

We only support PKCS#7 signed-data [RFC2315 sec 9] content at the top level,
so reject anything else.  Further, check that the version numbers in
SignedData and SignerInfo are 1 in both cases.

Note that we don't restrict the inner content type.  In the PKCS#7 code we
don't parse the data attached there, but merely verify the signature over
it.

Subject: X.509: Change recorded SKID & AKID to not include Subject or Issuer

The key identifiers fabricated from an X.509 certificate are currently:

 (A) Concatenation of serial number and issuer

 (B) Concatenation of subject and subjectKeyID (SKID)

When verifying one X.509 certificate with another, the AKID in the target
can be used to match the authoritative certificate.  The AKID can specify
the match in one or both of two ways:

 (1) Compare authorityCertSerialNumber and authorityCertIssuer from the AKID
     to identifier (A) above.

 (2) Compare keyIdentifier from the AKID plus the issuer from the target
     certificate to identifier (B) above.

When verifying a PKCS#7 message, the only available comparison is between
the IssuerAndSerialNumber field and identifier (A) above.

However, a subsequent patch adds CMS support.  Whilst CMS still supports a
match on IssuerAndSerialNumber as for PKCS#7, it also supports an
alternative - which is the SubjectKeyIdentifier field.  This is used to
match to an X.509 certificate on the SKID alone.  No subject information is
available to be used.

To this end change the fabrication of (B) above to be from the X.509 SKID
alone.  The AKID in keyIdentifier form then only matches on that and does
not include the issuer.

Subject: PKCS#7: Improve and export the X.509 ASN.1 time object decoder

Make the X.509 ASN.1 time object decoder fill in a time64_t rather than a
struct tm to make comparison easier (unfortunately, this makes readable
display less easy) and export it so that it can be used by the PKCS#7 code
too.

Further, tighten up its parsing to reject invalid dates (eg. weird
characters, non-existent hour numbers) and unsupported dates (eg. timezones
other than 'Z' or dates earlier than 1970).

Subject: PKCS#7: Appropriately restrict authenticated attributes and content
 type

A PKCS#7 or CMS message can have per-signature authenticated attributes
that are digested as a lump and signed by the authorising key for that
signature.  If such attributes exist, the content digest isn't itself
signed, but rather it is included in a special authattr which then
contributes to the signature.

Further, we already require the master message content type to be
pkcs7_signedData - but there's also a separate content type for the data
itself within the SignedData object and this must be repeated inside the
authattrs for each signer [RFC2315 9.2, RFC5652 11.1].

We should really validate the authattrs if they exist or forbid them
entirely as appropriate.  To this end:

 (1) Alter the PKCS#7 parser to reject any message that has more than one
     signature where at least one signature has authattrs and at least one
     that does not.

 (2) Validate authattrs if they are present and strongly restrict them.
     Only the following authattrs are permitted and all others are
     rejected:

     (a) contentType.  This is checked to be an OID that matches the
     	 content type in the SignedData object.

     (b) messageDigest.  This must match the crypto digest of the data.

     (c) signingTime.  If present, we check that this is a valid, parseable
     	 UTCTime or GeneralTime and that the date it encodes fits within
     	 the validity window of the matching X.509 cert.

     (d) S/MIME capabilities.  We don't check the contents.

     (e) Authenticode SP Opus Info.  We don't check the contents.

     (f) Authenticode Statement Type.  We don't check the contents.

     The message is rejected if (a) or (b) are missing.  If the message is
     an Authenticode type, the message is rejected if (e) is missing; if
     not Authenticode, the message is rejected if (d) - (f) are present.

     The S/MIME capabilities authattr (d) unfortunately has to be allowed
     to support kernels already signed by the pesign program.  This only
     affects kexec.  sign-file suppresses them (CMS_NOSMIMECAP).

     The message is also rejected if an authattr is given more than once or
     if it contains more than one element in its set of values.

 (3) Add a parameter to pkcs7_verify() to select one of the following
     restrictions and pass in the appropriate option from the callers:

     (*) VERIFYING_MODULE_SIGNATURE

	 This requires that the SignedData content type be pkcs7-data and
	 forbids authattrs.  sign-file sets CMS_NOATTR.  We could be more
	 flexible and permit authattrs optionally, but only permit minimal
	 content.

     (*) VERIFYING_FIRMWARE_SIGNATURE

	 This requires that the SignedData content type be pkcs7-data and
	 requires authattrs.  In future, this will require an attribute
	 holding the target firmware name in addition to the minimal set.

     (*) VERIFYING_UNSPECIFIED_SIGNATURE

	 This requires that the SignedData content type be pkcs7-data but
	 allows either no authattrs or only permits the minimal set.

     (*) VERIFYING_KEXEC_PE_SIGNATURE

	 This only supports the Authenticode SPC_INDIRECT_DATA content type
	 and requires at least an SpcSpOpusInfo authattr in addition to the
	 minimal set.  It also permits an SPC_STATEMENT_TYPE authattr (and
	 an S/MIME capabilities authattr because the pesign program doesn't
	 remove these).

     (*) VERIFYING_KEY_SIGNATURE
     (*) VERIFYING_KEY_SELF_SIGNATURE

	 These are invalid in this context but are included for later use
	 when limiting the use of X.509 certs.

 (4) The pkcs7_test key type is given a module parameter to select between
     the above options for testing purposes.  For example:

	echo 1 >/sys/module/pkcs7_test_key/parameters/usage
	keyctl padd pkcs7_test foo @s </tmp/stuff.pkcs7

     will attempt to check the signature on stuff.pkcs7 as if it contains a
     firmware blob (1 being VERIFYING_FIRMWARE_SIGNATURE).

Subject: crypto: cryptd - Remove reference to crypto_aead_crt

Pretty soon the crypto_aead encrypt/decrypt hooks will disappear
as they are now always identical to those in struct aead_alg.

This patch replaces the references to these hooks with the ones
from aead_alg instead.

Subject: crypto: null - Use NULL2 in Makefile

The Kconfig option NULL2 has been added as CRYPTO_MANAGER now
depends indirectly on NULL2.  However, the Makefile was not updated
to use the new option, resulting in potential build failures when
only NULL2 is enabled.

Subject: crypto: skcipher - Add top-level skcipher interface

This patch introduces the crypto skcipher interface which aims
to replace both blkcipher and ablkcipher.

It's very similar to the existing ablkcipher interface.  The
main difference is the removal of the givcrypt interface.  In
order to make the transition easier for blkcipher users, there
is a helper SKCIPHER_REQUEST_ON_STACK which can be used to place
a request on the stack for synchronous transforms.

Subject: crypto: algif_aead - fix for multiple operations on AF_ALG sockets

The tsgl scatterlist must be re-initialized after each
operation. Otherwise the sticky bits in the page_link will corrupt the
list with pre-mature termination or false chaining.

Subject: PKCS#7: Add OIDs for sha224, sha284 and sha512 hash algos and use
 them

Add OIDs for sha224, sha284 and sha512 hash algos and use them to select
the hashing algorithm.  Without this, something like the following error
might get written to dmesg:

[   31.829322] PKCS7: Unknown OID: [32] 2.16.840.1.101.3.4.2.3
[   31.829328] PKCS7: Unknown OID: [180] 2.16.840.1.101.3.4.2.3
[   31.829330] Unsupported digest algo: 55

Where the 55 on the third line is OID__NR indicating an unknown OID.

Subject: crypto: testmgr - don't copy from source IV too much

While the destination buffer 'iv' is MAX_IVLEN size,
the source 'template[i].iv' could be smaller, thus
memcpy may read read invalid memory.
Use crypto_skcipher_ivsize() to get real ivsize
and pass it to memcpy.
