an IPv6 address assigned to it, and if an incoming packet received on
one interface has a packet destination address that belongs to another
interface, the routing table is consulted to determine how to reach this
packet destination. Since the packet destination is an interface address,
the route table will return a host route with the loopback interface as
rt_ifp. The input code must recognize this fact, instead of using the
loopback interface, the input code performs a search to find the right
interface that owns the given IPv6 address.

This reverts part of r196460, so that sockets only return POLLHUP if both
directions are closed/error. Fifos get POLLHUP by closing the unused
direction immediately after creating the sockets.

- if POLLHUP is returned, POLLIN is always returned as well instead of only
when there is data left in the buffer to be read

When I wrote the pseudo-terminal driver for the MPSAFE TTY code, Robert
Watson and I agreed the best way to implement this, would be to let
posix_openpt() create a pseudo-terminal with proper permissions in place
and let grantpt() and unlockpt() be no-ops.
This isn't valid behaviour when looking at the spec. Because I thought
it was an elegant solution, I filed a bug report at the Austin Group
about this. In their last teleconference, they agreed on this subject.
This means that future revisions of POSIX may allow grantpt() and
unlockpt() to be no-ops if an open() on /dev/ptmx (if the implementation
has such a device) and posix_openpt() already do the right thing.
I'd rather put this in the manpage, because simply mentioning we don't
comply to any standard makes it look worse than it is. Right now we
don't, but at least we took care of it.

Say, a driver wants to have multiple console devices to pick from, you
would normally write down something like this:
CONSOLE_DRIVER(dev1);
CONSOLE_DRIVER(dev2);
Unfortunately, this means that you have to declare 10 cn routines,
instead of 5. It also isn't possible to initialize cn_arg on beforehand.
I noticed this restriction when I was implementing some of the console
bits for my vt(4) driver in my newcons branch. I have a single set of cn
routines (termcn_*) which are shared by all vt(4) console devices.
In order to solve this, I'm adding a separate consdev_ops structure,
which contains all the function pointers. This structure is referenced
through consdev's cn_ops field.
While there, I'm removing CONS_DRIVER() and cn_checkc, which have been
deprecated for years. They weren't used throughout the source, until the
Xen console driver showed up. CONSOLE_DRIVER() has been changed to do
the right thing. It now declares both the consdev and consdev_ops
structure and ties them together. In other words: this change doesn't
change the KPI for drivers that used the regular way of declaring
console devices.
If drivers want to use multiple console devices, they can do this as
follows:
static const struct consdev_ops mydriver_cnops = {
.cn_probe = mydriver_cnprobe,
...
};
static struct mydriver_softc cons0_softc = {
...
};
CONSOLE_DEVICE(cons0, mydriver_cnops, &cons0_softc);
static struct mydriver_softc cons1_softc = {
...
};
CONSOLE_DEVICE(cons1, mydriver_cnops, &cons1_softc);
