From 7f6cc9e8469afa87b9b83bf7bca7fe544a4dbe20 Mon Sep 17 00:00:00 2001 From: Tony Hutter Date: Thu, 11 Jul 2024 16:41:26 -0700 Subject: [PATCH] Linux 6.9: Fix UBSAN errors in zap_micro.c You can use the UBSAN_SANITIZE_* Kbuild options to exclude certain kernel objects from the UBSAN checks. We previously excluded zap_micro.o with: UBSAN_SANITIZE_zap_micro.o := n For some reason that didn't work for the 6.9 kernel, which wants us to use: UBSAN_SANITIZE_zfs/zap_micro.o := n Reviewed-by: Brian Behlendorf Signed-off-by: Tony Hutter Closes #16278 Closes #16330 --- module/Kbuild.in | 1 + 1 file changed, 1 insertion(+) diff --git a/module/Kbuild.in b/module/Kbuild.in index 9e44364b7584..4707452711f7 100644 --- a/module/Kbuild.in +++ b/module/Kbuild.in @@ -490,6 +490,7 @@ zfs-$(CONFIG_PPC64) += $(addprefix zfs/,$(ZFS_OBJS_PPC_PPC64)) UBSAN_SANITIZE_zap_leaf.o := n UBSAN_SANITIZE_zap_micro.o := n UBSAN_SANITIZE_sa.o := n +UBSAN_SANITIZE_zfs/zap_micro.o := n # Suppress incorrect warnings from versions of objtool which are not # aware of x86 EVEX prefix instructions used for AVX512.
