[PATCH] kernel/module: disable cfi for do_mod_ctors

CFI failure when both CONFIG_CONSTRUCTORS and CFI_CLANG enabled. CFI failure at do_init_module+0x100/0x384 (target: tsan.module_ctor+0x0/0xa98 [module_name_xx]; expected type: 0xa540670c) Disable cfi for do_mod_ctors to avoid cfi check on mod->ctors[i](). Signed-off-by: Joey Jiao --- ker

[PATCH v5] module: Add CONFIG_MODULE_DISABLE_INIT_FREE option

could be loaded into previous freed init pages of a previous loaded module. It is important to note that this option is intended for fuzzing tests only and should not be set as the default configuration in production builds. Signed-off-by: Joey Jiao --- kernel/module/Kconfig | 13
