crypto: ingenic - Drop kfree for memory allocated with devm_kzalloc

2020-08-21T04:43:51+00:00

It's not necessary to free memory allocated with devm_kzalloc and using kfree leads to a double free. Fixes: 190873a0ea45 ("crypto: ingenic - Add hardware RNG for Ingenic JZ4780 and X1000") Reported-by: Hulk Robot Signed-off-by: Wei Yongjun Reviewed-by: 周琰杰 (Zhou Yanjie) Signed-off-by: Herbert Xu

hwrng: core - remove redundant initialization of variable ret

2020-07-31T08:25:29+00:00

The variable ret is being initialized with a value that is never read and it is being updated later with a new value. The initialization is redundant and can be removed. Addresses-Coverity: ("Unused value") Signed-off-by: Colin Ian King Signed-off-by: Herbert Xu

crypto: ingenic - Add hardware RNG for Ingenic JZ4780 and X1000

hwrng: imx-rngc - enable driver for i.MX6

2020-07-23T07:34:19+00:00

i.MX6 SL, SLL, ULL, ULZ SoCs have an RNGB block. Since imx-rngc driver supports also rngb, let's enable it for these SoCs too. Signed-off-by: Horia Geantă Reviewed-by: Martin Kaiser Reviewed-by: Marco Felsch Signed-off-by: Herbert Xu

hwrng: ks-sa - Replace HTTP links with HTTPS ones

2020-07-16T11:49:06+00:00

Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

2020-07-16T11:49:01+00:00

There are multiple things in this file that requires kernel.h but it's only included through other header files indirectly. This patch adds a direct inclusion as those indirect inclusions may go away at any point. Signed-off-by: Herbert Xu
