kern: add a security knob to disable unprivileged access to kenv

2026-06-22T20:22:25+00:00

We sometimes store sensitive things in the kenv that get zapped, but we
really shouldn't rely on that zapping to actually happen.  Most
unprivileged processes don't really need to read from the kernel
environment in the first place, so add a knob that allows it to be
disabled.

Note that we consider jailed root to be unprivileged from this
perspective; they have their own meta/env concepts and we should
encourage users to take advantage of those for passing information to
jails.

sh: Improve function documentation

2026-06-16T20:23:18+00:00

* Mention that the function body can be in parentheses.  It is already
  implied since the function body can be any valid statement, but it may
  not be obvious to a reader who has only ever seen functions that used
  curly brackets and assumes that they are part of the function syntax.

* Remove the incorrect claim that a local statement may only occur at
  the top of a function.

* Show that a value may be assigned to a variable in a local statement.

* While here, replace unpaired double quotes with \(dq to avoid
  confusing syntax highlighters.

cp(1): fix -P documentation to reflect it works without -R

2026-06-10T12:35:03+00:00

Since commit 97e13037915c, the -P flag works without -R as
required by POSIX. Update the man page to state that only -H
and -L are ignored without -R, while -P can be used independently.

tests: Avoid sleep when causing a write error

2026-06-03T22:10:08+00:00

Cause a write error using a fifo and wait, rather than needing a sleep
to wait for something to terminate. This is faster and avoids a
potential test failure on a heavily loaded system.

Using /dev/full would be simpler, but it is not portable enough (it
tends not to be available in jails, even). Starting programs with stdout
not open or only open for read/execute/search may have unexpected side
effects.
