Hi all, After merging the selinux tree, today's linux-next build (i386 defconfig) failed like this: In file included from include/linux/kernel.h:31, from security/selinux/ss/ebitmap.c:16: security/selinux/ss/ebitmap.c: In function 'ebitmap_read': include/linux/kern_levels.h:5:25: error: format '%ld' expects argument of type 'long int', but argument 3 has type 'u32' {aka 'unsigned int'} [-Werror=format=] 5 | #define KERN_SOH "\001" /* ASCII Start Of Header */ | ^~~~~~ include/linux/printk.h:429:25: note: in definition of macro 'printk_index_wrap' 429 | _p_func(_fmt, ##__VA_ARGS__); \ | ^~~~ include/linux/printk.h:500:9: note: in expansion of macro 'printk' 500 | printk(KERN_ERR pr_fmt(fmt), ##__VA_ARGS__) | ^~~~~~ include/linux/kern_levels.h:11:25: note: in expansion of macro 'KERN_SOH' 11 | #define KERN_ERR KERN_SOH "3" /* error conditions */ | ^~~~~~~~ include/linux/printk.h:500:16: note: in expansion of macro 'KERN_ERR' 500 | printk(KERN_ERR pr_fmt(fmt), ##__VA_ARGS__) | ^~~~~~~~ security/selinux/ss/ebitmap.c:464:17: note: in expansion of macro 'pr_err' 464 | pr_err("SELinux: ebitmap: high bit %d is not equal to the expected value %ld\n", | ^~~~~~ cc1: all warnings being treated as errors Caused by commit 0142c56682fb ("selinux: reject invalid ebitmaps") I have reverted that commit for today. -- Cheers, Stephen Rothwell
