It's a document from June 2015.
DESCRIPTION
The NetBSD kernel provides several synchronization and interrupt control
primitives. This manpage aims at giving an overview of these interfaces
and their proper application. This document includes also basic kernel
thread control primitives and rough overview of the NetBSD kernel design.
Part of interfaces are missing, like new mechanisms for networking SMP,
as this documentation page predates them.
Initial review back in 2015 by Thomas Klausner <wiz>
This example presents a C module with its device (/dev entry) and its
content generator with algorithm defined in Lua state. The Lua state can
be changed dynamically from userland, without interruption of read(2) over
the device.
This is an example how to call Lua code from C.
* restored --logfile support as a few people complained it vanished
The new logging code even makes the overall binary size smaller
on most platforms.
* BPF filter now trims garbage trailing the payload
OK, it's not garbage, but userland doesn't know some drivers append
FCS to it.
* support NetBSD's RO_MSGFILTER socket option to reduce avoid context
switching for route(4) messages that don't interest us.
* Don't open sockets if just sending signals.
* HMAC-MD5 test's now check expectations in code rather than relying
on visual confirmation.
* added eloop-bench to test performance of eloop with available
polling mechanisms.
Some system does not detect ioapic when "boot -1", disable acpi, and so on.
In such cases, msi/msix doesn't work, so disable them.
This patch is implemented by nonaka@n.o, I just commit by proxy, thanks.
Add new defines:
- CPU_FPU_SAVE (15)
int: FPU Instructions layout
* to use this, CPU_OSFXSR must be true
* 0: FSAVE
* 1: FXSAVE
* 2: XSAVE
* 3: XSAVEOPT
- CPU_FPU_SAVE_SIZE (16)
int: FPU Instruction layout size
- CPU_XSAVE_FEATURES (17)
quad: FPU XSAVE features
Bump CPU_MAXID from 15 to 18.
These values were prepared originally to be exported without ASCIIZ name to
be used as handler. These values are useful to get FPU accessors in a
debugger easier to implement on x86 (PT_SETFPREG, PT_GETFPREG).
This interface handles all supported x86 targets. In the older (i386) and
less featured CPUs check first osfxsr (OS uses FXSAVE/FXRSTOR).
According to sys/arch/x86/include/cpu.h r.1.65 this was prepared to be
exported beyond simple CTL_CREATE node.

- Check if setkey correctly handles algorithms for AH/ESP
- Check IPsec of transport mode with AH/ESP over IPv4/IPv6
- Check IPsec of tunnel mode with AH/ESP over IPv4/IPv6
Note that we should modularize netipsec and reduce reverse symbol references
(referencing symbols of netipsec from net, netinet and netinet6) though,
the task needs lots of code changes. Prior to doing so, rumpifying it and
having ATF tests should be useful.
