Re: [9fans] segattach off-by-one?

[erik quanstrom]

the patch i posted yesterday was wrong.  i forgot about
automatic address assigment with segattach.  this works,
but perhaps it would be better to round va before checking
if va == 0?

/n/quanstro//sys/src/9/port/segment.c:642,648 - segment.c:642,648
        Segment *s, *os;
        Physseg *ps;
  
-       if((va !=0 && va < BY2PG) || va >= USTKTOP)
+       if(va != 0 && va >= USTKTOP)
                error(Ebadarg);
  
        validaddr((ulong)name, 1, 0);
