| Subject: crypto: ecc - fix CRYPTO_DEFAULT_RNG dependency |
| |
| From: Arnd Bergmann <arnd@arndb.de> |
| |
| [ Upstream commit 38aa192a05f22f9778f9420e630f0322525ef12e ] |
| |
| The ecc.c file started out as part of the ECDH algorithm but got |
| moved out into a standalone module later. It does not build without |
| CRYPTO_DEFAULT_RNG, so now that other modules are using it as well we |
| can run into this link error: |
| |
| aarch64-linux-ld: ecc.c:(.text+0xfc8): undefined reference to `crypto_default_rng' |
| aarch64-linux-ld: ecc.c:(.text+0xff4): undefined reference to `crypto_put_default_rng' |
| |
| Move the 'select CRYPTO_DEFAULT_RNG' statement into the correct symbol. |
| |
| Fixes: 0d7a78643f69 ("crypto: ecrdsa - add EC-RDSA (GOST 34.10) algorithm") |
| Fixes: 4e6602916bc6 ("crypto: ecdsa - Add support for ECDSA signature verification") |
