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
Remove entries:
- research support PT_SYSCALL & PT_STEP combined like in Linux
- GDB Remote Protocol expects a case with a step with a signal to be sent,
this is currently unsupported on NetBSD
Implemented as PT_SETSTEP and PT_CLEARSTEP.
Remove:
- support QPassSignals (PT_SET_SIGPASS/PT_GET_SIGPASS) in the kernel, a way to
stop routing a set of signals to tracer as they are uninteresting - GDB and
LLDB expect this feature
This interface has been abandoned and will be handled on the debugger level.
