by calling NDAT(&nd, dirvp) after NDINIT().
Right now the implementation is vile and unspeakable to avoid changing
the kernel ABI; this way we can get openat() and friends into 6.1. I
will rectify the mess and bump the kernel once things are working.
the system and eventually cause a watchdog timer to reset. Instead use
softints for "small" number of packets and use a workqueue thread for large
numbers. This allows receive processing to be handling at normal priorities
and won't starve out other parts of the system.
ranges to the default dma tag. This has the side effect of making most initial
bus_dmamem_allocs trying to get memory from the first 256MB which is coherent
on this platform.

more difficult. For the reference, see "Reflection Scan: an Off-Path Attack
on TCP" by Jan Wrobel.
caused by the sequence of passing two fd's with two sendmsg()'s,
then doing a read() and a recvmsg(). The read() calls dom_dispose()
which discards both messages in the mbuf, and sets the fp's in the
array to NULL. Linux dequeues only one message per read() so the
second recvmsg() gets the fd from the second message. This fix
just avoids the NULL pointer de-reference, making the second
recvmsg() to fail. It is dubious to pass fd's with stream sockets
and expect mixing read() and recvmsg() to work. Plus processing
one control message per read() changes the current semantics and
should be examined before applied. In addition there is a race between
dom_externalize() and dom_dispose(): what happens in a multi-threaded
network stack when one thread disposes where the other externalizes
the same array?

Set _mandb in man.conf to same value as was used before.

GCC/i386 has code to lower the required alignment for long long to 32bit
as the CPU doesn't need more. It is also using the same mode for setting
up the MMX registers and in turn, the stack slots reserved for spilling
require 32bit alignment. The actual vector types used keep the original
64bit alignment, so when the compiler wants to spill a MMX register, it
hits an assertion. Fix this by using the vector type as raw type for MMX
registers.
setting up the console and how to work around the problem. This
is an initial stab at solving PR/35348 for NetBSD 6.0. After 6.0
is released, a better solution can be done for 6.1.
