The functions time_before, time_before_eq, time_after, and time_after_eq are more robust for comparing jiffies against other values.
So following patch implements usage of the time_after() macro, defined at linux/jiffies.h, which deals with wrapping correctly Cc: [EMAIL PROTECTED] Signed-off-by: S.Çağlar Onur <[EMAIL PROTECTED]> --- fs/binfmt_aout.c | 7 ++++--- 1 files changed, 4 insertions(+), 3 deletions(-) diff --git a/fs/binfmt_aout.c b/fs/binfmt_aout.c index a1bb224..72757fe 100644 --- a/fs/binfmt_aout.c +++ b/fs/binfmt_aout.c @@ -6,6 +6,7 @@ #include <linux/module.h> +#include <linux/jiffies.h> #include <linux/time.h> #include <linux/kernel.h> #include <linux/mm.h> @@ -374,14 +375,14 @@ static int load_aout_binary(struct linux_binprm * bprm, struct pt_regs * regs) } else { static unsigned long error_time, error_time2; if ((ex.a_text & 0xfff || ex.a_data & 0xfff) && - (N_MAGIC(ex) != NMAGIC) && (jiffies-error_time2) > 5*HZ) + (N_MAGIC(ex) != NMAGIC) && time_after(jiffies, error_time2 + 5 * HZ)) { printk(KERN_NOTICE "executable not page aligned\n"); error_time2 = jiffies; } if ((fd_offset & ~PAGE_MASK) != 0 && - (jiffies-error_time) > 5*HZ) + time_after(jiffies, error_time + 5 * HZ)) { printk(KERN_WARNING "fd_offset is not page aligned.
