* crypto: Test all of the AES-CCM KAT vectors.John Baldwin2021-10-212-39/+56
| | | | | | | | | | | | | | | | | | | | | Previously, only test vectors which used the default nonce and tag sizes (12 and 16, respectively) were tested. This now tests all of the vectors. This exposed some additional issues around requests with an empty payload (which wasn't supported) and an empty AAD (which falls back to CIOCCRYPT instead of CIOCCRYPTAEAD). - Make use of the 'ivlen' and 'maclen' fields for CIOGSESSION2 to test AES-CCM vectors with non-default nonce and tag lengths. - Permit requests with an empty payload. - Permit an input MAC for requests without AAD.

| | | | | | | | | | | | | | | Repeating the default WARNS here makes it slightly more difficult to experiment with default WARNS changes, e.g. if we did something absolutely bananas and introduced a WARNS=7 and wanted to try lifting the default to that. Drop most of them; there is one in the blake2 kernel module, but I suspect it should be dropped -- the default WARNS in the rest of the build doesn't currently apply to kernel modules, and I haven't put too much thought into whether it makes sense to make it so.

* Refactor driver and consumer interfaces for OCF (in-kernel crypto).John Baldwin2020-03-273-13/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - The linked list of cryptoini structures used in session initialization is replaced with a new flat structure: struct crypto_session_params. This session includes a new mode to define how the other fields should be interpreted. Available modes include: - COMPRESS (for compression/decompression) - CIPHER (for simply encryption/decryption) - DIGEST (computing and verifying digests) - AEAD (combined auth and encryption such as AES-GCM and AES-CCM) - ETA (combined auth and encryption using encrypt-then-authenticate) Additional modes could be added in the future (e.g. if we wanted to support TLS MtE for AES-CBC in the kernel we could add a new mode for that. TLS modes might also affect how AAD is interpreted, etc.) The flat structure also includes the key lengths and algorithms as before. However, code doesn't have to walk the linked list and switch on the algorithm to determine which key is the auth key vs encryption key. The 'csp_auth_*' fields are always used for auth keys and settings and 'csp_cipher_*' for cipher. (Compression algorithms are stored in csp_cipher_alg.) - Drivers no longer register a list of supported algorithms. This doesn't quite work when you factor in modes (e.g. a driver might support both AES-CBC and SHA2-256-HMAC separately but not combined for ETA). Instead, a new 'crypto_probesession' method has been added to the kobj interface for symmteric crypto drivers. This method returns a negative value on success (similar to how device_probe works) and the crypto framework uses this value to pick the "best" driver. There are three constants for hardware (e.g. ccr), accelerated software (e.g. aesni), and plain software (cryptosoft) that give preference in that order. One effect of this is that if you request only hardware when creating a new session, you will no longer get a session using accelerated software. Another effect is that the default setting to disallow software crypto via /dev/crypto now disables accelerated software. Once a driver is chosen, 'crypto_newsession' is invoked as before. - Crypto operations are now solely described by the flat 'cryptop' structure. The linked list of descriptors has been removed. A separate enum has been added to describe the type of data buffer in use instead of using CRYPTO_F_* flags to make it easier to add more types in the future if needed (e.g. wired userspace buffers for zero-copy). It will also make it easier to re-introduce separate input and output buffers (in-kernel TLS would benefit from this). Try to make the flags related to IV handling less insane: - CRYPTO_F_IV_SEPARATE means that the IV is stored in the 'crp_iv' member of the operation structure. If this flag is not set, the IV is stored in the data buffer at the 'crp_iv_start' offset. - CRYPTO_F_IV_GENERATE means that a random IV should be generated and stored into the data buffer. This cannot be used with CRYPTO_F_IV_SEPARATE. If a consumer wants to deal with explicit vs implicit IVs, etc. it can always generate the IV however it needs and store partial IVs in the buffer and the full IV/nonce in crp_iv and set CRYPTO_F_IV_SEPARATE. The layout of the buffer is now described via fields in cryptop. crp_aad_start and crp_aad_length define the boundaries of any AAD. Previously with GCM and CCM you defined an auth crd with this range, but for ETA your auth crd had to span both the AAD and plaintext (and they had to be adjacent). crp_payload_start and crp_payload_length define the boundaries of the plaintext/ciphertext. Modes that only do a single operation (COMPRESS, CIPHER, DIGEST) should only use this region and leave the AAD region empty. If a digest is present (or should be generated), it's starting location is marked by crp_digest_start. Instead of using the CRD_F_ENCRYPT flag to determine the direction of the operation, cryptop now includes an 'op' field defining the operation to perform. For digests I've added a new VERIFY digest mode which assumes a digest is present in the input and fails the request with EBADMSG if it doesn't match the internally-computed digest. GCM and CCM already assumed this, and the new AEAD mode requires this for decryption. The new ETA mode now also requires this for decryption, so IPsec and GELI no longer do their own authentication verification. Simple DIGEST operations can also do this, though there are no in-tree consumers. To eventually support some refcounting to close races, the session cookie is now passed to crypto_getop() and clients should no longer set crp_sesssion directly. - Assymteric crypto operation structures should be allocated via crypto_getkreq() and freed via crypto_freekreq(). This permits the crypto layer to track open asym requests and close races with a driver trying to unregister while asym requests are in flight. - crypto_copyback, crypto_copydata, crypto_apply, and crypto_contiguous_subsegment now accept the 'crp' object as the first parameter instead of individual members. This makes it easier to deal with different buffer types in the future as well as separate input and output buffers. It's also simpler for driver writers to use. - bus_dmamap_load_crp() loads a DMA mapping for a crypto buffer. This understands the various types of buffers so that drivers that use DMA do not have to be aware of different buffer types. - Helper routines now exist to build an auth context for HMAC IPAD and OPAD. This reduces some duplicated work among drivers. - Key buffers are now treated as const throughout the framework and in device drivers. However, session key buffers provided when a session is created are expected to remain alive for the duration of the session. - GCM and CCM sessions now only specify a cipher algorithm and a cipher key. The redundant auth information is not needed or used. - For cryptosoft, split up the code a bit such that the 'process' callback now invokes a function pointer in the session. This function pointer is set based on the mode (in effect) though it simplifies a few edge cases that would otherwise be in the switch in 'process'. It does split up GCM vs CCM which I think is more readable even if there is some duplication. - I changed /dev/crypto to support GMAC requests using CRYPTO_AES_NIST_GMAC as an auth algorithm and updated cryptocheck to work with it. - Combined cipher and auth sessions via /dev/crypto now always use ETA mode. The COP_F_CIPHER_FIRST flag is now a no-op that is ignored. This was actually documented as being true in crypto(4) before, but the code had not implemented this before I added the CIPHER_FIRST flag. - I have not yet updated /dev/crypto to be aware of explicit modes for sessions. I will probably do that at some point in the future as well as teach it about IV/nonce and tag lengths for AEAD so we can support all of the NIST KAT tests for GCM and CCM. - I've split up the exising crypto.9 manpage into several pages of which many are written from scratch. - I have converted all drivers and consumers in the tree and verified that they compile, but I have not tested all of them. I have tested the following drivers: - cryptosoft - aesni (AES only) - blake2 - ccr and the following consumers: - cryptodev - IPsec - ktls_ocf - GELI (lightly) I have not tested the following: - ccp - aesni with sha - hifn - kgssapi_krb5 - ubsec - padlock - safe - armv8_crypto (aarch64) - glxsb (i386) - sec (ppc) - cesa (armv7) - cryptocteon (mips64) - nlmsec (mips64) Discussed with: cem Relnotes: yes Sponsored by: Chelsio Communications Differential Revision: https://reviews.freebsd.org/D23677 Notes: svn path=/head/; revision=359374

* Fix encoding issues with python 3Enji Cooper2019-05-211-6/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In python 3, the default encoding was switched from ascii character sets to unicode character sets in order to support internationalization by default. Some interfaces, like ioctls and packets, however, specify data in terms of non-unicode encodings formats, either in host endian (`fcntl.ioctl`) or network endian (`dpkt`) byte order/format. This change alters assumptions made by previous code where it was all data objects were assumed to be basestrings, when they should have been treated as byte arrays. In order to achieve this the following are done: * str objects with encodings needing to be encoded as ascii byte arrays are done so via `.encode("ascii")`. In order for this to work on python 3 in a type agnostic way (as it anecdotally varied depending on the caller), call `.encode("ascii")` only on str objects with python 3 to cast them to ascii byte arrays in a helper function name `str_to_ascii(..)`. * `dpkt.Packet` objects needing to be passed in to `fcntl.ioctl(..)` are done so by casting them to byte arrays via `bytes()`, which calls `dpkt.Packet__str__` under the covers and does the necessary str to byte array conversion needed for the `dpkt` APIs and `struct` module. In order to accomodate this change, apply the necessary typecasting for the byte array literal in order to search `fop.name` for nul bytes. This resolves all remaining python 2.x and python 3.x compatibility issues on amd64. More work needs to be done for the tests to function with i386, in general (this is a legacy issue).

* Fix `KAT(CCM)?Parser` file descriptor leaksEnji Cooper2019-05-212-28/+90
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make `KAT(CCM)?Parser` into a context suite-capable object by implementing `__enter__` and `__exit__` methods which manage opening up the file descriptors and closing them on context exit. This implementation was decided over adding destructor logic to a `__del__` method, as there are a number of issues around object lifetimes when dealing with threading cleanup, atexit handlers, and a number of other less obvious edgecases. Plus, the architected solution is more pythonic and clean. Complete the iterator implementation by implementing a `__next__` method for both classes which handles iterating over the data using a generator pattern, and by changing `__iter__` to return the object instead of the data which it would iterate over. Alias the `__next__` method to `next` when working with python 2.x in order to maintain functional compatibility between the two major versions. As part of this work and to ensure readability, push the initialization of the parser objects up one layer and pass it down to a helper function. This could have been done via a decorator, but I was trying to keep it simple for other developers to make it easier to modify in the future. This fixes ResourceWarnings with python 3.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The upstream repository is on github BLAKE2/libb2. Files landed in sys/contrib/libb2 are the unmodified upstream files, except for one difference: secure_zero_memory's contents have been replaced with explicit_bzero() only because the previous implementation broke powerpc link. Preferential use of explicit_bzero() is in progress upstream, so it is anticipated we will be able to drop this diff in the future. sys/crypto/blake2 contains the source files needed to port libb2 to our build system, a wrapped (limited) variant of the algorithm to match the API of our auth_transform softcrypto abstraction, incorporation into the Open Crypto Framework (OCF) cryptosoft(4) driver, as well as an x86 SSE/AVX accelerated OCF driver, blake2(4). Optimized variants of blake2 are compiled for a number of x86 machines (anything from SSE2 to AVX + XOP). On those machines, FPU context will need to be explicitly saved before using blake2(4)-provided algorithms directly. Use via cryptodev / OCF saves FPU state automatically, and use via the auth_transform softcrypto abstraction does not use FPU. The intent of the OCF driver is mostly to enable testing in userspace via /dev/crypto. ATF tests are added with published KAT test vectors to validate correctness.

* Add ccp(4): experimental driver for AMD Crypto Co-ProcessorConrad Meyer2018-01-181-10/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Registers TRNG source for random(4) * Finds available queues, LSBs; allocates static objects * Allocates a shared MSI-X for all queues. The hardware does not have separate interrupts per queue. Working interrupt mode driver. * Computes SHA hashes, HMAC. Passes cryptotest.py, cryptocheck tests. * Does AES-CBC, CTR mode, and XTS. cryptotest.py and cryptocheck pass. * Support for "authenc" (AES + HMAC). (SHA1 seems to result in "unaligned" cleartext inputs from cryptocheck -- which the engine cannot handle. SHA2 seems to work fine.) * GCM passes for block-multiple AAD, input lengths Largely based on ccr(4), part of cxgbe(4). Rough performance averages on AMD Ryzen 1950X (4kB buffer): aesni: SHA1: ~8300 Mb/s SHA256: ~8000 Mb/s ccp: ~630 Mb/s SHA256: ~660 Mb/s SHA512: ~700 Mb/s cryptosoft: ~1800 Mb/s SHA256: ~1800 Mb/s SHA512: ~2700 Mb/s As you can see, performance is poor in comparison to aesni(4) and even cryptosoft (due to high setup cost). At a larger buffer size (128kB), throughput is a little better (but still worse than aesni(4)): aesni: SHA1:~10400 Mb/s SHA256: ~9950 Mb/s ccp: ~2200 Mb/s SHA256: ~2600 Mb/s SHA512: ~3800 Mb/s cryptosoft: ~1750 Mb/s SHA256: ~1800 Mb/s SHA512: ~2700 Mb/s AES performance has a similar story: aesni: 4kB: ~11250 Mb/s 128kB: ~11250 Mb/s ccp: ~350 Mb/s 128kB: ~4600 Mb/s cryptosoft: ~1750 Mb/s 128kB: ~1700 Mb/s This driver is EXPERIMENTAL. You should verify cryptographic results on typical and corner case inputs from your application against a known- good implementation.

* aesni(4): Add support for x86 SHA intrinsicsConrad Meyer2017-09-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some x86 class CPUs have accelerated intrinsics for SHA1 and SHA256. Provide this functionality on CPUs that support it. This implements CRYPTO_SHA1, CRYPTO_SHA1_HMAC, and CRYPTO_SHA2_256_HMAC. Correctness: The cryptotest.py suite in tests/sys/opencrypto has been enhanced to verify SHA1 and SHA256 HMAC using standard NIST test vectors. The test passes on this driver. Additionally, jhb's cryptocheck tool has been used to compare various random inputs against OpenSSL. This test also passes. Rough performance averages on AMD Ryzen 1950X (4kB buffer): aesni: SHA1: ~8300 Mb/s SHA256: ~8000 Mb/s cryptosoft: ~1800 Mb/s SHA256: ~1800 Mb/s So ~4.4-4.6x speedup depending on algorithm choice. This is consistent with the results the Linux folks saw for 4kB buffers. The driver borrows SHA update code from sys/crypto sha1 and sha256. The intrinsic step function comes from Intel under a 3-clause BSDL.[0] The intel_sha_extensions_sha<foo>_intrinsic.c files were renamed and lightly modified (added const, resolved a warning or two; included the sha_sse header to declare the functions).

| | | | | | | | | | | | | | | When crypto_newsession() is given a request for an unsupported capability, raise a more specific error than EINVAL. This allows cryptotest.py to skip some HMAC tests that a driver does not support.

* Convert some idioms over to py3k-compatible idiomsEnji Cooper2017-09-242-54/+57
| | | | | | | | | | | | | - Import print_function from __future__ and use print(..) instead of `print ..`. - Use repr instead of backticks when the object needs to be dumped, unless print(..) can do it lazily. Use str instead of backticks as appropriate for simplification reasons. This doesn't fully convert these modules over py3k. It just gets over some of the trivial compatibility hurdles.
