Hi, So, I noticed that asm-gemeric/bug.h defines BUG() without a log level:
#ifndef HAVE_ARCH_BUG #define BUG() do { \ printk("BUG: failure at %s:%d/%s()!\n", __FILE__, __LINE__, __func__); \ Seems like it should have one? Also, I think we might want to examine WARN() a bit... it doesn't have a log level either, but only a fraction of callers set one: $ git grep -E 'WARN(_TAINT|)(_RATELIMIT|_ONCE|)\([^\)]' | grep -v KERN_ | wc -l 2735 $ git grep -E 'WARN(_TAINT|)(_RATELIMIT|_ONCE|)\([^\)]' | grep KERN_ | wc -l 77 If I'm reading checkpatch.pl correctly, it doesn't warn about missing log levels on WARN calls, but I think it should. How do you think is best to clean this up? Mainly, I'd like to add a format string to BUG, or introduce a new BUGish call that takes a format... -Kees -- Kees Cook Nexus Security
