Description Mark J. Cox 2005-10-10 14:46:04 UTC 
+++ This bug was initially created as a clone of Bug #170277 +++

The orinoco driver can send uninitialized data exposing random pieces of the
system memory.  This happens because data is not padded with zeroes when its
length needs to be increased.

For the 2.6 upstream fix see
http://linux.bkbits.net:8080/linux-2.6/cset@43434a71q9eUGtXKCTmWyYIPqFjEUQ

However Alan Cox said "skb_padto already does the if() so the extra if
(skb->len < len) just wastes resources"
