netbsd_elfcore_procinfo is still in version 1.
cpi_siglwp is stored in the same netbsd_elfcore_procinfo version (1).
The size of struct is stored in cpi_cpisize and the struct can be
expanded without versioning the struct.
The new member is caled f_mntfromlabel and it is the dkw_wname
of the corresponding wedge. This is now used by df -W to display
the mountpoint name as NAME=
parses the output of cpuctl, and executes "cpuctl offline" for each CPU
that has SmtID!=0.
The default is "smtoff=NO", which means that SMT remains enabled.
when unmounting tmpfs file systems at shutdown time, avoid unmounting
a tmpfs created by init on /dev - behaviour overridable from rc.conf.
By default all tmpfs that have device nodes are not mounted.
is of poor quality, and is now an obstacle to MP-ification. It was removed
ten years ago from FreeBSD for the same reason.
This retires a big user of the mbuf API, and will ease maintenance of the
kernel.
Originally, MKCRYPTO was introduced because the United States
classified cryptography as a munition and restricted its export. The
export controls were substantially relaxed fifteen years ago, and are
essentially irrelevant for software with published source code.
In the intervening time, nobody bothered to remove the option after
its motivation -- the US export restriction -- was eliminated. I'm
not aware of any other operating system that has a similar option; I
expect it is mainly out of apathy for churn that we still have it.
Today, cryptography is an essential part of modern computing -- you
can't use the internet responsibly without cryptography.
The position of the TNF board of directors is that TNF makes no
representation that MKCRYPTO=no satisfies any country's cryptography
regulations.
My personal position is that the availability of cryptography is a
basic human right; that any local laws restricting it to a privileged
few are fundamentally immoral; and that it is wrong for developers to
spend effort crippling cryptography to work around such laws.
As proposed on tech-crypto, tech-security, and tech-userlevel to no
objections:

P.S. Reviewing all the uses of MKCRYPTO in src revealed a lot of
*bad* crypto that was conditional on it, e.g. DES in telnet... That
should probably be removed too, but on the grounds that it is bad,
not on the grounds that it is (nominally) crypto.
If it's yes, all local symbols of shared libraries are stripped
(default). If it's no, only temporary local symbols are stripped;
for example, symbols of static functions are kept. Keeping such
symbols is useful on using DTrace for userland libraries and
getting a backtrace from a rump server loading modules (shared
libraries).
Proposed and discussed on tech-kern and tech-toolchain
Note cpi_siglwp addition in NetBSD-2.0 and retaining the procinfo ver. 1.
Note ELF_NOTE_NETBSD_CORE_AUXV (2) addition in NetBSD-8.0.
Update the HISTORY section.
