From a14a9add73341bc3c355250bc43282e022bff95c Mon Sep 17 00:00:00 2001 From: Cheyenne Wills <cwills@sinenomine.net> Date: Wed, 07 Feb 2024 15:25:10 -0700 Subject: [PATCH] Linux 6.8: Add function prototypes for krb5 The external files for heimdal/krb5 do not provide function prototypes in a header file that is used when building files that we use from heimdal/krb5 (e.g. crypto.c). These functions are flagged due to missing prototypes when building against a Linux 6.8 kernel (which sets the -Wmissing-declarations and -Wmissing-prototypes compiler flags as default). Linux 6.8 commit: 'Makefile.extrawarn: turn on missing-prototypes globally' (0fcb70851f). When building against a kernel with CONFIG_WERROR=y, the build fails. We cannot modify the external source files, however there is the local OpenAFS include file, krb5_locl.h, that does contain OpenAFS specific changes. Add declarations to krb5_locl.h for the functions defined in the heimdal/krb5 source. There are no functional changes with this commit.
