Subject: [OPERA] Another potential bug in /arch/mips/kernel/sysirix.c
Date: Thu, 20 May 2004 17:26:36 -0500 [thread overview]
Message-ID: <001801c43eb9$835b09f0$76f6ae80@Turandot> (raw)
We ran our bug detection tool upon Linux 2.6.6, and found some potential
errors.
We would sincerely appreciate your help if anyone can confirm whether they
are bugs or not.
Linux 2.6.6, /arch/mips/kernel/sysirix.c, Line 1642
1634 asmlinkage int irix_statvfs64(char *fname, struct irix_statvfs64 *buf)
1635 {
1636 struct nameidata nd;
1637 struct kstatfs kbuf;
1638 int error, i;
1639
1640 printk("[%s:%d] Wheee.. irix_statvfs(%s,%p)\n",
1641 current->comm, current->pid, fname, buf);
!1642 error = verify_area(VERIFY_WRITE, buf, sizeof(struct
irix_statvfs));
1643 if(error)
1644 goto out;
May be changed to:
1634 asmlinkage int irix_statvfs64(char *fname, struct irix_statvfs64 *buf)
1635 {
1636 struct nameidata nd;
1637 struct kstatfs kbuf;
1638 int error, i;
1639
1640 printk("[%s:%d] Wheee.. irix_statvfs(%s,%p)\n",
1641 current->comm, current->pid, fname, buf);
!1642 error = verify_area(VERIFY_WRITE, buf, sizeof(struct
irix_statvfs64));
1643 if(error)
1644 goto out;
