      [IPV4]: Fix byte value boundary check in do_ip_getsockopt(). · 951e07c9
      David S. Miller authored
      This fixes kernel bugzilla 10371.
      
      As reported by M.Piechaczek@osmosys.tv, if we try to grab a
      char sized socket option value, as in:
      
        unsigned char ttl = 255;
        socklen_t     len = sizeof(ttl);
        setsockopt(socket, IPPROTO_IP, IP_MULTICAST_TTL, &ttl, &len);
      
        getsockopt(socket, IPPROTO_IP, IP_MULTICAST_TTL, &ttl, &len);
      
      The ttl returned will be wrong on big-endian, and on both little-
      endian and big-endian the next three bytes in userspace are written
      with garbage.
      
      It's because of this test in do_ip_getsockopt():
      
      	if (len < sizeof(int) && len > 0 && val>=0 && val<255) {
      
      It should allow a 'val' of 255 to pass here, but it doesn't so it
      copies a full 'int' back to userspace.
      
      On little-endian that will write the correct value into the location
      but it spams on the next three bytes in userspace.  On big endian it
      writes the wrong value into the location and spams the next three
      bytes.

      [NET]: srandom32 fixes for networking v2 · 61407f80
      Andi Kleen authored
      - Let it update the state of all CPUs. The network stack goes
      into pains to feed the current IP addresses in, but it is not very
      effective if that is only done for some random CPU instead of all.
      So change it to feed bits into all CPUs.  I decided to do that lockless 
      because well somewhat random results are ok.
      
      v2: Drop rename so that this patch doesn't depend on x86 maintainers
