Hi All,
I have recently (since yesterday) started building the mainline kernel with clang-14 and I am seeing a build failure with allmodconfig.
In file included from drivers/net/ethernet/huawei/hinic/hinic_devlink.c:15: In file included from ./include/linux/netlink.h:7: In file included from ./include/linux/skbuff.h:15: In file included from ./include/linux/time.h:60: In file included from ./include/linux/time32.h:13: In file included from ./include/linux/timex.h:67: In file included from ./arch/x86/include/asm/timex.h:5: In file included from ./arch/x86/include/asm/processor.h:22: In file included from ./arch/x86/include/asm/msr.h:11: In file included from ./arch/x86/include/asm/cpumask.h:5: In file included from ./include/linux/cpumask.h:12: In file included from ./include/linux/bitmap.h:11: In file included from ./include/linux/string.h:253: ./include/linux/fortify-string.h:344:4: error: call to __write_overflow_field declared with 'warning' attribute: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Werror,-Wattribute-warning] __write_overflow_field(p_size_field, size);
After a bisect it pointed to 281d0c962752 ("fortify: Add Clang support"). Since it was introduced in v5.18, not sure if its already reported before.
-- Regards Sudip
