* [client] Export the only-owner-writable path check from elevate
Pure refactor, no behavior change: the existing checkOnlyOwnerWritable gets a
thin exported wrapper so callers outside the elevation path can reuse it. No
call site changes here.
* [client] Validate the saved service parameters before applying them
The install reads <stateDir>/service.json and applies it to the service it then
registers: its arguments, its config path and its environment. The restricted
ACL that saveServiceParams puts on the state directory is applied when the file
is written, which is not necessarily before the file is first read, so the
install now checks the file rather than assuming it.
A file whose ownership or permissions are not the ones saveServiceParams
produces is treated as absent, and the install proceeds with its defaults. The
check covers the directories above the file as well, so what is checked is what
is read.
* [client] Restrict which environment variables the service is registered with
--service-env, and the service.json it persists to, accepted any name. A small
set of them decides how a process resolves the executables and libraries it
loads, and the daemon needs none of those: it now refuses them when they are
passed explicitly, and drops them with a warning when they come back from a
service.json written by an older version, so an upgrade does not fail over a
variable nobody needs.
* [client] Resolve netsh by absolute path
The lookup consulted PATH first and fell back to System32, in both the copy the
userspace firewall uses and the one that tears the interface down. It now asks
Windows for the system directory, so the resolution no longer depends on the
environment the service happens to be started with.
* [client] Move the System32 lookup into a package both callers share
Pure refactor, no behavior change: client/iface and client/firewall/uspfilter
carried a copy each of the same function, and neither imports the other, so the
body moves to client/internal/wincmd — alongside winregistry, which is where
the client's other Windows-only helper already lives. Both call sites now read
wincmd.System32("netsh").
* [client] Cover the System32 lookup with a test
Asserts what the previous commits changed: the lookup is absolute, and neither
PATH nor %SystemRoot% moves it.
* [client] Refuse the loader environment families by prefix
Review follow-up on the previous commit:
- LD_* and DYLD_* are now refused whole rather than name by name. Their members
differ per platform and libc and grow with new OS releases, so a list of them
is out of date as soon as it is written — DYLD_FALLBACK_LIBRARY_PATH and
DYLD_FALLBACK_FRAMEWORK_PATH were already missing from it.
- The names are folded to upper case only on Windows, where a variable is the
same one however it is spelled. Elsewhere the environment is case-sensitive,
so Path and PATH are two variables and only the exact spelling is the one that
is read; the fold refused the wrong one.
- TEMP and TMP stay in the denylist, but the rationale and the message now say
what they actually decide: where the service writes, not what it loads.
* Add support for disabling profiles feature via command line flag
* Add profiles disabling flag to service command
* Refactor profile menu initialization and enhance error notifications in event handlers
Added host configurators for Linux, Windows, and macOS.
The host configurator will update the peer system configuration
directing DNS queries according to its capabilities.
Some Linux distributions don't support split (match) DNS or custom ports,
and that will be reported to our management system in another PR
