From: Jiri Slaby Date: Thu, 16 Apr 2026 07:07:30 +0200 Subject: Linux kernel: leancrypto_kernel_rng_tester: include linux/hex.h MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit References: build-fix Patch-mainline: submitted https://github.com/smuellerDD/leancrypto/pull/59 Since commit 24c776355f40 ("kernel.h: drop hex.h and update all hex.h users"), hex.h is not included from kernel.h. It needs to be included in each file using the functions. That is the case in leancrypto_kernel_rng_tester: ../drng/tests/leancrypto_kernel_rng_tester.c: In function 'lc_seeded_rng_test': ../drng/tests/leancrypto_kernel_rng_tester.c:43:9: error: implicit declaration of function 'bin2hex' [-Wimplicit-function-declaration] 43 | bin2hex(hex, outbuf, sizeof(outbuf)); | ^~~~~~~ Signed-off-by: Jiri Slaby --- drng/tests/leancrypto_kernel_rng_tester.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drng/tests/leancrypto_kernel_rng_tester.c b/drng/tests/leancrypto_kernel_rng_tester.c index 358e982e6975..a4e2028f9c3c 100644 --- a/drng/tests/leancrypto_kernel_rng_tester.c +++ b/drng/tests/leancrypto_kernel_rng_tester.c @@ -20,6 +20,7 @@ #include #include +#include #include static int lc_seeded_rng_test(void) -- 2.53.0
