request, the FreeBSD NFS client will quickly back off to a excessively
long wait (days, then weeks) before retrying the request.
Change the behavior of the FreeBSD NFS client to match the behavior of
the reference NFS client implementation (Solaris). This provides a fixed
delay of 10 seconds between each retry by default. A sysctl, called
nfs3_jukebox_delay, is now available to tune the delay. Unlike Solaris,
the sysctl value on FreeBSD is in seconds, rather than in HZ.

sockets as long as the sockets have not been aborted or detached. Do
not try to free the socket in pru_detach(), since sofree() will do so,
if needed, once pru_detach() returns.
Annotate a bug in ddp_abort(), which fails to free the socket; this
is probably OK as ddp_abort() should never be called, so should
instead be deleted.
pcb's allocated:
- Universally ensure (and assert) that so_pcb is not NULL, removing lots
of checks and error cases. Don't free the pcb without clearing the
so_pcb pointer.
- Don't try to free the socket in pru_detach(), since the caller will
immediately free the socket.
- Do retain the sotryfree() in pru_abort() for now, although eventually
the caller will do it unconditionally.

defined for an in-use socket. This allows us to eliminate countless tests
of whether so_pcb is non-NULL, eliminating dozens of error cases. For
now, retain the call to sotryfree() in the uipc_abort() path, but this
will eventually move to soabort().
These new assumptions should be largely correct, and will become more so
as the socket/pcb reference model is fixed. Removing the notion that
so_pcb can be non-NULL is a critical step towards further fine-graining
of the UNIX domain socket locking, as the so_pcb reference no longer
needs to be protected using locks, instead it is a property of the socket
life cycle.
allocation patterns that involve a relatively even mixture of many
different size classes.
Reduce the chunk size from 16 MB to 2 MB. Since chunks are now carved up
using an address-ordered first best fit policy, VM map fragmentation is
much less likely, which makes smaller chunks not as much of a risk. This
reduces the virtual memory size of most applications.
Remove redzones, since program buffer overruns are no longer as likely to
corrupt malloc data structures.
Remove the C MALLOC_OPTIONS flag, and add H and S.

into one function syscons_configure_keyboard(). Call new function from
both syscons_start() and sysconst_setkeyboard(). The reason for this
is because syscons_start() will (re)configure both keyboard and screen
settings. Apparently, some graphics cards have problems with running
vidcontrol(1) while X11 is running.
Remove "/etc/rc.d/syscons restart" from /etc/devd.conf. It is no longer
required. Using "/etc/rc.d/syscons setkeyboard" is enough. This also
should fix annoying "syscons not running?" message.

especially for vchans. It turns out that channel numbering always depend
on d->devcount counter (which keep increasing), while PCMMKMINOR() truncate
everything to 8bit length. At some point the truncation cause the newly
created character device overlapped with the existence one, causing erratic
overall system behaviour and panic. Easily reproduce with something like:
(Luckily, only root can reproduce this)
while : ; do
sysctl hw.snd.pcm0.vchans=200
sysctl hw.snd.pcm0.vchans=100
done
- Enforce channel/chardev numbering within 8bit boundary. Return E2BIG
if necessary.
- Traverse d->channels SLIST and try to reclaim "free" counter during channel
creation. Don't rely on d->devcount at all.
- Destroy vchans in reverse order.
Anyway, this is not the fault of vchans. It is just that vchans are so cute
and begging to be abused ;) . Don't blame her.
