>Release: FreeBSD 2.2.2-RELEASE i386
>Environment:
Found in FreeBSD 2.2.2.
>Description:
/usr/sbin/quot calls lseek() without casting the offset to off_t.
This makes breakage on filesystems where the offset is > 2**31.
>How-To-Repeat:
Use quot on a big filesystem (4gig?).
>Fix:
gnat@himalia (quot) diff quot.c new-quot.c

< if (lseek(fd,ino_to_fsba(super,last) << super->fs_fshift,0) < 0
