This patch does not add new features. The main work is to refactor and simplify the implementation of SM4 NEON, which is reflected in the following aspects: The accelerated implementation supports the arbitrary number of blocks, not just multiples of 8, which simplifies the implementation and brings some optimization acceleration for data that is not aligned by 8 blocks. When loading the input data, use the ld4 instruction to replace the original ld1 instruction as much as possible, which will save the cost of matrix transposition of the input data. Use 8-block parallelism whenever possible to speed up matrix transpose and rotation operations, instead of up to 4-block parallelism. Signed-off-by:

This patch adds the NEON acceleration implementation of the SM3 hash algorithm. The main algorithm is based on SM3 NEON accelerated work of the libgcrypt project. Benchmark on T-Head Yitian-710 2.75 GHz, the data comes from the 326 mode of tcrypt, and compares the performance data of sm3-generic and sm3-ce. The abscissas are blocks of different lengths. The data is tabulated and the unit is Mb/s: update-size | 16 64 256 1024 2048 4096 8192 ---------------+-------------------------------------------------------- sm3-generic | 185.24 221.28 301.26 307.43 300.83 308.82 308.91 sm3-neon | 171.81 220.20 322.94 339.28 334.09 343.61 343.87 sm3-ce | 227.48 333.48 502.62 527.87 520.45 534.91 535.40 Signed-off-by:

The top level print banners have a leading newline. It's not entirely clear why this exists, but it makes it harder to parse tcrypt test output using a script. Drop said newlines. tcrypt output before this patch: [...] testing speed of rfc4106(gcm(aes)) (rfc4106-gcm-aesni) encryption [...] test 0 (160 bit key, 16 byte blocks): 1 operation in 2320 cycles (16 bytes) tcrypt output with this patch: [...] testing speed of rfc4106(gcm(aes)) (rfc4106-gcm-aesni) encryption [...] test 0 (160 bit key, 16 byte blocks): 1 operation in 2320 cycles (16 bytes) Signed-off-by:Anirudh Venkataramanan <anirudh.venkataramanan@intel.com> Signed-off-by:

The pr_fmt() define includes KBUILD_MODNAME, and so there's no need for pr_err() to also print it. Drop module name from the print string. Signed-off-by:
-
Anirudh Venkataramanan authored
Currently, there's mixed use of printk() and pr_info()/pr_err(). The latter prints the module name (because pr_fmt() is defined so) but the former does not. As a result there's inconsistency in the printed output. For example: modprobe mode=211: [...] test 0 (160 bit key, 16 byte blocks): 1 operation in 2320 cycles (16 bytes) [...] test 1 (160 bit key, 64 byte blocks): 1 operation in 2336 cycles (64 bytes) modprobe mode=215: [...] tcrypt: test 0 (160 bit key, 16 byte blocks): 1 operation in 2173 cycles (16 bytes) [...] tcrypt: test 1 (160 bit key, 64 byte blocks): 1 operation in 2241 cycles (64 bytes) Replace all instances of printk() with pr_info()/pr_err() so that the module name is printed consistently.

For some test cases, a line break gets inserted between the test banner and the results. For example, with mode=211 this is the output: [...] testing speed of rfc4106(gcm(aes)) (rfc4106-gcm-aesni) encryption [...] test 0 (160 bit key, 16 byte blocks): [...] 1 operation in 2373 cycles (16 bytes) --snip-- [...] testing speed of gcm(aes) (generic-gcm-aesni) encryption [...] test 0 (128 bit key, 16 byte blocks): [...] 1 operation in 2338 cycles (16 bytes) Similar behavior is seen in the following cases as well: modprobe tcrypt mode=212 modprobe tcrypt mode=213 modprobe tcrypt mode=221 modprobe tcrypt mode=300 sec=1 modprobe tcrypt mode=400 sec=1 This doesn't happen with mode=215: [...] tcrypt: testing speed of multibuffer rfc4106(gcm(aes)) (rfc4106-gcm-aesni) encryption [...] tcrypt: test 0 (160 bit key, 16 byte blocks): 1 operation in 2215 cycles (16 bytes) --snip-- [...] tcrypt: testing speed of multibuffer gcm(aes) (generic-gcm-aesni) encryption [...] tcrypt: test 0 (128 bit key, 16 byte blocks): 1 operation in 2191 cycles (16 bytes) This print inconsistency is because printk() is used instead of pr_cont() in a few places. Change these to be pr_cont(). checkpatch warns that pr_cont() shouldn't be used. This can be ignored in this context as tcrypt already uses pr_cont(). Signed-off-by:

Increase the buffer to prevent stack overflow by fuzz test. The maximum length of the qos configuration buffer is 256 bytes. Currently, the value of the 'val buffer' is only 32 bytes. The sscanf does not check the dest memory length. So the 'val buffer' may stack overflow. Signed-off-by:

We want to leverage keyring to store sensitive keys, and then use those keys for symmetric encryption via the crypto API. Among the key types we wish to support are: user, logon, encrypted, and trusted. User key types are already able to have their data copied to user space, but logon does not support this. Further, trusted and encrypted keys will return their encrypted data back to user space on read, which does not make them ideal for symmetric encryption. To support symmetric encryption for these key types, add a new ALG_SET_KEY_BY_KEY_SERIAL setsockopt() option to the crypto API. This allows users to pass a key_serial_t to the crypto API to perform symmetric encryption. The behavior is the same as ALG_SET_KEY, but the crypto key data is copied in kernel space from a keyring key, which allows for the support of logon, encrypted, and trusted key types. Keyring keys must have the KEY_(POS|USR|GRP|OTH)_SEARCH permission set to leverage this feature. This follows the asymmetric_key type where key lookup calls eventually lead to keyring_search_rcu() without the KEYRING_SEARCH_NO_CHECK_PERM flag set. Signed-off-by:

The RK3399 has 2 rk3288 compatible crypto device named crypto0 and crypto1. The only difference is lack of RSA in crypto1. We need to add driver support for 2 parallel instance as only one need to register crypto algorithms. Then the driver will round robin each request on each device. For avoiding complexity (device bringup after a TFM is created), PM is modified to be handled per request. Signed-off-by:
