* kern: add a security knob to disable unprivileged access to kenvKyle Evans2026-06-221-1/+9
| | | | | | | | | | | | | | | | | 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.

* tests: Avoid sleep when causing a write errorJilles Tjoelker2026-06-031-7/+8
| | | | | | | | | | | | | | 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. Reviewed by: ngie, des Differential Revision: https://reviews.freebsd.org/D57213

| | | | | | | | | | | | | | | | | | When reading from standard input with editline history enabled, increase buffer size to accomodate long lines so that history is recorded correctly. Cleanup el_gets() handling avoiding potentially dangerous retention of pointers to editline buffers across calls. Ensure struct parsefile objects are properly zero initialised when created. Remove push argument from setinputstring() and simplify logic as it was always called with a value of one and as was written was potentially dangerous if ever called with a value of zero. This commit does not fix long lines when history is enabled but editing is not (e.g. if there is no terminal).

* sh/tests: Cut down builtins/read12.0 by 2 secondsJilles Tjoelker2026-05-232-7/+10

Also, fix some assertions in builtins/read11.0 and builtins/read12.0. If `set -e` is in effect, `foo` in `foo && bar` is considered tested and therefore a failure does not cause the shell to exit.

| | | | | | | | | | | | | | | | If the /sbin/init binary is broken somehow, the way out is to set the loader environment variable init_path to something else. The most natural choice would be either /bin/sh or /rescue/sh. Unfortunately, this does not work because the init process starts withoud stdin/out descriptors. Make it nicer to users by teaching /bin/sh startup code to open standard descriptors on /dev/console if the shell is run as init.

| | | | | | | | | | | | | | | | | Things like `{ some_program; } >/dev/null` use vfork, so use vfork similarly for things like `some_program >/dev/null`. This cannot be done for command substitutions, because of two problems: * Redirections might cause the error message for later redirections or for an unknown command to be sent to the pipe (to be substituted), and this might cause a deadlock if the message is too long. * The assignment of the pipe needs to come before instead of after the redirections.

| | | | | | | | | | | | | | | The uuidgen(2) system call enforces a hard upper limit of 2048 UUIDs per invocation. uuidgen(1) previously attempted to generate arbitrary counts in a single call and allocated memory accordingly, leading to EINVAL errors, unnecessary memory usage, and potential overflow risks. Generate UUIDs in fixed-size batches, streaming output incrementally while preserving existing semantics. Mirror the kernel limit explicitly since it is not exposed via a public interface.
