From 361fa7f813e7056cecdb24f3582ab0ad4a088e4e Mon Sep 17 00:00:00 2001 From: Thorsten Blum Date: Mon, 11 Aug 2025 11:24:57 +0200 Subject: [PATCH] crypto: octeontx2 - Call strscpy() with correct size argument In otx2_cpt_dl_custom_egrp_create(), strscpy() is called with the length of the source string rather than the size of the destination buffer. This is fine as long as the destination buffer is larger than the source string, but we should still use the destination buffer size instead to call strscpy() as intended. And since 'tmp_buf' is a fixed-size buffer, we can safely omit the size argument and let strscpy() infer it using sizeof().
