- A new per-interface knob IFF_ND6_NO_RADR and sysctl IPV6CTL_NO_RADR.
This controls if accepting a route in an RA message as the default route.
The default value for each interface can be set by net.inet6.ip6.no_radr.
The system wide default value is 0.
- A new sysctl: net.inet6.ip6.norbit_raif. This controls if setting R-bit in
NA on RA accepting interfaces. The default is 0 (R-bit is set based on
net.inet6.ip6.forwarding).
Background:
IPv6 host/router model suggests a router sends an RA and a host accepts it for
router discovery. Because of that, KAME implementation does not allow
accepting RAs when net.inet6.ip6.forwarding=1. Accepting RAs on a router can
make the routing table confused since it can change the default router
unintentionally.
However, in practice there are cases where we cannot distinguish a host from
a router clearly. For example, a customer edge router often works as a host
against the ISP, and as a router against the LAN at the same time. Another
example is a complex network configurations like an L2TP tunnel for IPv6
connection to Internet over an Ethernet link with another native IPv6 subnet.
In this case, the physical interface for the native IPv6 subnet works as a
host, and the pseudo-interface for L2TP works as the default IP forwarding
route.
Problem:
Disabling processing RA messages when net.inet6.ip6.forwarding=1 and
accepting them when net.inet6.ip6.forward=0 cause the following practical
issues:
- A router cannot perform SLAAC. It becomes a problem if a box has
multiple interfaces and you want to use SLAAC on some of them, for
example. A customer edge router for IPv6 Internet access service
using an IPv6-over-IPv6 tunnel sometimes needs SLAAC on the
physical interface for administration purpose; updating firmware
and so on (link-local addresses can be used there, but GUAs by
SLAAC are often used for scalability).
- When a host has multiple IPv6 interfaces and it receives multiple RAs on
them, controlling the default route is difficult. Router preferences
defined in RFC 4191 works only when the routers on the links are
under your control.
Details of Implementation Changes:
Router Advertisement messages will be accepted even when
net.inet6.ip6.forwarding=1. More precisely, the conditions are as
follow:
(ACCEPT_RTADV && !NO_RADR && !ip6.forwarding)
=> Normal RA processing on that interface. (as IPv6 host)
(ACCEPT_RTADV && (NO_RADR || ip6.forwarding))
=> Accept RA but add the router to the defroute list with
rtlifetime=0 unconditionally. This effectively prevents
from setting the received router address as the box's
default route.
(!ACCEPT_RTADV)
=> No RA processing on that interface.
ACCEPT_RTADV and NO_RADR are per-interface knob. In short, all interface
are classified as "RA-accepting" or not. An RA-accepting interface always
processes RA messages regardless of ip6.forwarding. The difference caused by
NO_RADR or ip6.forwarding is whether the RA source address is considered as
the default router or not.
R-bit in NA on the RA accepting interfaces is set based on
net.inet6.ip6.forwarding. While RFC 6204 W-1 rule (for CPE case) suggests
a router should disable the R-bit completely even when the box has
net.inet6.ip6.forwarding=1, I believe there is no technical reason with
doing so. This behavior can be set by a new sysctl net.inet6.ip6.norbit_raif
(the default is 0).
Usage:
# ifconfig fxp0 inet6 accept_rtadv
=> accept RA on fxp0
# ifconfig fxp0 inet6 accept_rtadv no_radr
=> accept RA on fxp0 but ignore default route information in it.
# sysctl net.inet6.ip6.norbit_no_radr=1
=> R-bit in NAs on RA accepting interfaces will always be set to 0.
sending. What happens otherwise is that the sender splits all the
traffic into 32k chunks, while the receiver is waiting for the whole
packet. Then for a certain packet sizes, particularly 66607 bytes in
my case, the communication stucks to secondary is expecting to
read one chunk of 66607 bytes, while primary is sending two chunks
of 32768 bytes and third chunk of 1071. Probably due to TCP windowing
and buffering the final chunk gets stuck somewhere, so neither server
not client can make any progress.
This patch also protect from short reads, as according to the manual

end offset and then calculate size. Also use stripesize and stripeoffset

but inet in theory). Unfortunately people are used to
ifconfig IF up/down
etc. as well, so use a fallback of "link". Adjust the man page

The rational is that most disks are now running with 4K
sectors. While they can (slowly) simulate 512-byte sectors
by doing a read-modify-write, it is desirable to avoid this
functionality. By raising the minimum filesystem allocation
to 4K, the filesystem will never trigger the small sector
emulation.
Also, the growth of disk sizes has lead us to double the

Such RAID levels are now supported:

For any all of these RAID levels and metadata formats this class supports

disk removal and insertion, rebuilding, dirty shutdown detection
and resynchronization, bad sector recovery, faulty disks tracking,
hot-spare disks. For Intel and Promise formats there is support multiple

structure. We don't operate directly on descriptors, but on
proto_conns.
- Add wrap method to wrap descriptor with proto_conn.
- Remove methods to send and receive descriptors and implement this
functionality as additional argument to send and receive methods.

If timeout argument to proto_connect() is -1, then the caller needs to use
this new function to wait for connection.
This change is in preparation for capsicum, where sandboxed worker wants
to ask main process to connect in worker's behalf and pass descriptor
to the worker. Because we don't want the main process to wait for the
connection, it will start async connection and pass descriptor to the
worker who will be responsible for waiting for the connection to finish.

to syslog if we run in background.
- Asserts in proto.c that method we want to call is implemented and remove
dummy methods from protocols implementation that are only there to abort
the program with nice message.

When requesting a scan and one is already in progess, e.g. while in scan
state, we happily wait for a scan done notification. Though, this
notification might never be sent, e.g. if we are trying to find a network
to associate to and there is none. Instead of always waiting for a
notification just do so if a new scan has been started. For both cases the
scan cache is used to report available networks even if the content might
not be fresh.

is deferred for the time it takes to flush the TX queue. This work being
done the scan then is continued, but only if it is marked to do so. As
the 'ifconfig scan' request is meant to be used after the interface is
brought up, request a background scan by default. This behaviour is
already documented in manual page.
This fixes on possible case where 'ifconfig scan' hangs infinitely.

Accepting connections and handshaking in secondary is still done before
dropping privileges. It should be implemented by only accepting connections in
privileged main process and passing connection descriptors to the worker, but
is not implemented yet.

- chrooting to /var/empty (user hast home directory),
- setting groups to 'hast' (user hast primary group),
- setting real group id, effective group id and saved group id to 'hast',
- setting real user id, effective user id and saved user id to 'hast'.
At the end verify that those operations where successfull.

we expect to be open. Also assert that they point at expected type.
Because openlog(3) API is unable to tell us descriptor number it is using, we
have to close syslog socket, remember assert message in local buffer and if we
fail on assertion, reopen syslog socket and log the message.

PJDLOG_RVERIFY() - always check expression and on false log the given message
and exit.
PJDLOG_RASSERT() - check expression when NDEBUG is not defined and on false log
given message and exit.
PJDLOG_ABORT() - log the given message and exit.
