Dear Chris,the following commit breaks my Linux build. commit 990486c8af044f89bddfbde1d1cf9fde449bedbf Author: Chris Metcalf <[email protected]> Date: Tue Oct 6 12:37:41 2015 -0400strscpy: zero any trailing garbage bytes in the destination It's possible that the destination can be shadowed in userspace(as, for example, the perf buffers are now). So we should take care not to leak data that could be inspected by userspace. The error message is: lib/string.c: In function 'strscpy': lib/string.c:209:4: error: implicit declaration of function 'zero_bytemask' [-Werror=implicit-function-declaration] cc1: some warnings being treated as errors I compile the kernel for PowerPC (32 bit) with the attached config.
Ah, it appears that big-endian powerpc does not provide zero_bytemask(), only little-endian. I'll fix this in v3 of the patch series - thanks! -- Chris Metcalf, EZChip Semiconductor http://www.ezchip.com -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
