char/mwave: Adjust io port register size

2022-01-27T07:46:16+00:00

[ Upstream commit f5912cc19acd7c24b2dbf65a6340bf194244f085 ] Using MKWORD() on a byte-sized variable results in OOB read. Expand the size of the reserved area so both MKWORD and MKBYTE continue to work without overflow. Silences this warning on a -Warray-bounds build: drivers/char/mwave/3780i.h:346:22: error: array subscript 'short unsigned int[0]' is partly outside array bounds of 'DSP_ISA_SLAVE_CONTROL[1]' [-Werror=array-bounds] 346 | #define MKWORD(var) (*((unsigned short *)(&var))) | ~^~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/char/mwave/3780i.h:356:40: note: in definition of macro 'OutWordDsp' 356 | #define OutWordDsp(index,value) outw(value,usDspBaseIO+index) | ^~~~~ drivers/char/mwave/3780i.c:373:41: note: in expansion of macro 'MKWORD' 373 | OutWordDsp(DSP_IsaSlaveControl, MKWORD(rSlaveControl)); | ^~~~~~ drivers/char/mwave/3780i.c:358:31: note: while referencing 'rSlaveControl' 358 | DSP_ISA_SLAVE_CONTROL rSlaveControl; | ^~~~~~~~~~~~~ Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2") Signed-off-by: Kees Cook Link: https://lore.kernel.org/r/20211203084206.3104326-1-keescook@chromium.org Signed-off-by: Greg Kroah-Hartman Signed-off-by: Sasha Levin

Linux-2.6.12-rc2

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
