R. Silva # Date: Thu Jun 22 17:14:51 2023 -0600 # # sparc: openpromio: Address -Warray-bounds warning # # One-element arrays are deprecated, and we are replacing them with flexible # array members instead. So, replace one-element array with flexible-array # member in struct openpromio. # # Address the following warning found after building (with GCC-13) sparc # with sparc64_defconfig: # In function 'opromgetprop', # inlined from 'openprom_sunos_ioctl.isra' at drivers/sbus/char/openprom.c:312:11: # drivers/sbus/char/openprom.c:141:24: warning: array subscript 1 is above array bounds of 'char[1]' [-Warray-bounds=] # 141 | op->oprom_array[len] = '\0'; # | ~~~~~~~~~~~~~~~^~~~~ # In file included from drivers/sbus/char/openprom.c:31: # arch/sparc/include/uapi/asm/openpromio.h: In function 'openprom_sunos_ioctl.isra': # arch/sparc/include/uapi/asm/openpromio.h:16:17: note: while referencing 'oprom_array' # 16 | char oprom_array[1]; /* Holds property names and values. */ # | ^~~~~~~~~~~ # # This helps with the ongoing efforts to tighten the FORTIFY_SOURCE # routines on memcpy() and help us make progress towards globally # enabling -Warray-bounds. # # This results in no differences in binary output. # # Link: https://github.com/KSPP/linux/issues/79 # Link: https://github.com/KSPP/linux/issues/322 # Reviewed-by: Kees Cook # Signed-off-by: Gustavo A.
