buffersize is enforced strictly, this supplies sufficient entropy
payload to act as seed material. Discourage general use of this
API, but lock down this function name as the go-to for userland
PRNG seeding. Improve documentation.

I accepted that he's right (again) to seperate this out from heavy
sysctl API and this will simply a variety of things. Functionname
is not used by anyone in the ports tree, so we guess we can use it.
Shocking that no application has a function called this.

interfaces when the kernel is livelocked, only do it for the current
pool and defer the other updates.
This allow us to get rid of an interface list iteration in a critical
path.
Ridding the libc crank since this change introduce an ABI break.

requested but the waited-on process did not terminate, return zero
bytes instead of kernel stack garbage.

use the domain specific tree initialisation method for this since that one
is multipath enabled and assumes that the radix node is part of a struct
rtentry. This code uses a different struct and so the multipath modifies
wrong fields and breaks stuff in mysterious ways.
Since we only support AF_INET here anyway simplify the code and only have
one radix_node_head pointer instead of AF_MAX ones.

Ergo, it only needs to call uvm_map_protect() if the requested
permissions didn't include UVM_PROT_WRITE.

to the process's vmspace and filedescs. struct proc continues to
keep copies of the pointers, copying them on fork, clearing them
on exit, and (for vmspace) refreshing on exec.
Also, make uvm_swapout_threads() thread aware, eliminating p_swtime
in kernel.

pulled by <uvm/uvm_extern.h> and turn uvm_total() into a private
function.
The preferred way to get memory stats is through the VM_UVMEXP
sysctl(3) since VM_METER is just a wrapper on top of it. In the
kernel, use `uvmexp' directly instead of uvm_total().
This change does not remove <sys/vmmeter.h> from <uvm/uvm_extern.h>
to give some more time to port maintainers to fix their ports.

gcc does not like hh in kprintf and it does not make any difference due
to integer promotion rules. While there, remove some h's, too.

the /var/crash/programname/ directory, as root. For instance,
# mkdir /var/crash/bgpd/
# chmod 700 /var/crash/bgpd/ # If you skip this step, you are a moron
# sysctl kern.nosuidcoredump=3
# bgpd
# pkill -ABRT bgpd
# ls /var/crash/bgpd/
14764.core 23207.core 6423.core
Of course, in real life the idea is that you don't kill the daemon but it
crashes and you collect parallel cores. Careful you don't fill your /var.
Further tuneables are being considered.
Sorry to be picking on bgpd for this example. I've watched the "too
difficult to debug privsep code" angst for far too long.

sleeping in systrace_exit() doesn't reorder them and lead to a panic.

Avoid the confusion by using an appropriate name for the variable.
Note that since routing domain IDs are a subset of the set of routing
table IDs, the following idiom is correct:
rtableid = rdomain
But to get the routing domain ID corresponding to a given routing table
ID, you must call rtable_l2(9).

localhost connections.
The plan is to always use the routing table for addresses and routes
resolutions, so there is no future for an option that wants to bypass
it. This option has never been implemented for IPv6 anyway, so let's
just remove the IPv4 bits that you weren't aware of.
