crypto: tcrypt - add ffdhe2048(dh) test

2024-03-08T11:23:25+00:00

Commit 7dce59819750 ("crypto: dh - implement ffdheXYZ(dh) templates") implemented the said templates. Add ffdhe2048(dh) test as it is the fastest one. This is a requirement for the FIPS certification. Signed-off-by: Vladis Dronov Signed-off-by: Herbert Xu

crypto: tcrypt - Remove cfb and ofb

2023-12-08T03:59:46+00:00

Remove tests for CFB/OFB. Signed-off-by: Herbert Xu

crypto: api - Move low-level functions into algapi.h

2023-04-14T10:59:34+00:00

A number of low-level functions were exposed in crypto.h. Move them into algapi.h (and internal.h). Signed-off-by: Herbert Xu

crypto: tcrypt - include larger key sizes in RFC4106 benchmark

2023-01-20T10:29:31+00:00

RFC4106 wraps AES in GCM mode, and can be used with larger key sizes than 128/160 bits, just like AES itself. So add these to the tcrypt recipe so they will be benchmarked as well. Signed-off-by: Ard Biesheuvel Signed-off-by: Herbert Xu

crypto: tcrypt - Fix multibuffer skcipher speed test mem leak

2022-11-25T09:39:18+00:00

In the past, the data for mb-skcipher test has been allocated twice, that means the first allcated memory area is without free, which may cause a potential memory leakage. So this patch is to remove one allocation to fix this error. Fixes: e161c5930c15 ("crypto: tcrypt - add multibuf skcipher...") Signed-off-by: Zhang Yiqun Signed-off-by: Herbert Xu

crypto: tcrypt - add SM4 cts-cbc/xts/xcbc test

2022-11-04T09:34:21+00:00

Added CTS-CBC/XTS/XCBC tests for SM4 algorithms, as well as corresponding speed tests, this is to test performance-optimized implementations of these modes. Signed-off-by: Tianjia Zhang Signed-off-by: Herbert Xu

crypto: tcrypt - Drop leading newlines from prints

2022-11-04T09:33:22+00:00

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 Signed-off-by: Herbert Xu

crypto: tcrypt - Drop module name from print string

2022-11-04T09:33:22+00:00

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 Signed-off-by: Herbert Xu

crypto: tcrypt - Use pr_info/pr_err

2022-11-04T09:33:22+00:00

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.

crypto: tcrypt - Use pr_cont to print test results

2022-11-04T09:33:22+00:00

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().
