2. It didn't work when a non-root built world the second time
3. It didn't use DESTDIR which had potential to conflict backups

It also previously featured "NO_BACKUP" which turned off the automatic
backup feature.  To fix the #2 problem, the install timestamp has been
removed, so to avoid unwanted backups for multiple installworlds after

Sepherosa Ziehau [Tue, 9 Apr 2013 03:06:39 +0000 (11:06 +0800)]
ip/udp: Fix IP source address setting for multicast address bound socket

It is a common practice to bind UDP socket to multicast address to enjoy
kernel level destination multicast address and port filtering.  However,
if data are sent on this kind of socket, source address of the IP packet
will be the bound multicast address?!

Two fixes are added to address this bug:

1) Don't set IP source address in udp_output(), if the inpcb's laddr is
   multicast address.  Instead the IP source address is set to INADDR_ANY,
   so ip_output() could pick up a proper IP source address.

2) With 1) in place, it is possible that IP source address is INADDR_ANY
   before the ifnet.if_output() using following steps:
   - If the IP_MULTICAST_IF socket option is set to iface0
   - The iface0's last IP address is unset, before the ip_output()

   This condition could easily be reproduced by using test/mcast:
   mcast -m 224.2.2.2 -p 3000 -i iface0_ip -D 10
   During the 10sec delay, wipe out all IP addresses from iface0

   Well, even without 1), raw IP still could generate IP packet using
   INADDR_ANY as source address.

   Two checks on the source IP address are added to ip_output() before
   ifnet.if_output()
   - IP source address should not be INADDR_ANY
   - IP source address should not be multicast address

   And for multicast IP packets, if the IP source address could be
   determined, they will not be looped back and forwarded.

Sometimes disks designed to operate in low power mode by default

performance.

This commit adds the 'feature' command to natacontrol(8) which
can be used to tweak the 'advanced power management' and 'automatic
acoustic management' features. Their current setting could already

I'd like this to be possible with camcontrol(8) too for CAM attached

have to integrate ATA into CAM too before that is possible.
