2026-05-29feat(cli,parser): support custom profile names and overhaul WireGuard .conf ↵James O'Doherty
parser for robustness - CLI: - Add optional `[name]` argument to `wg-wrap profile import <path> [name]` to allow overriding the imported profile name. If not provided, it falls back to the derived filename. - Update `README.md` command documentation to reflect custom profile names and list the `wg-wrap profile stop <name>` subcommand. - Expand `internal/cli/profile_test.go` to cover derived vs custom-named profile imports. - WG Configuration Parser: - Overhaul `pkg/wgconf/wgconf.go` to support case-insensitivity on section headers (e.g. `[peer]`, `[interface]`) and key names (e.g. `privatekey`, `allowedips`). - Implement robust trailing comment stripping (both `#` and `;`) while preserving inline comment-like characters in cryptographic keys (e.g. `key-with-hash-inside#123`) using whitespace-padded match logic. - Clean up and normalize leading/trailing spaces/tabs on parsed keys, values, and list elements (e.g. `AllowedIPs` and `DNS` fields). - Gracefully ignore unrecognized keys (e.g. `MTU`, `ListenPort`, `PresharedKey`) without returning errors. - Add comprehensive tests in `pkg/wgconf/wgconf_test.go` covering inline/block comments, formatting variations, unrecognized keys, and case-insensitivity.
2026-05-29feat(dns): implement unprivileged DNS isolation, precedence order, and ↵James O'Doherty
profile configuration Completed the remaining roadmap and documentation requirements by implementing robust unprivileged DNS management, completing the profile configuration subcommand, and resolving data-plane transition socket crashes. Detailed changes: - **DNS Isolation**: Implemented `ConfigureResolvConf` in `internal/wireguard/wireguard.go` to override `/etc/resolv.conf` within the unprivileged network/mount namespace. Transitioned the mount namespace to private propagation (`MS_PRIVATE`) and safely bind-mounted a temporary resolv.conf file over `/etc/resolv.conf` without mutating the host's configuration. - **DNS Precedence Order**: Integrated CLI flag `--dns-server`, parsed `.conf` interface DNS parameters, and added a safe default fallback (`1.1.1.1`) to ensure absolute host DNS leak prevention inside wrapped sessions. - **Socket Duplication in FDBind**: Resolved a lifecycle panic in `FDBind` where `wireguard-go` called `Close` and `Open` during device state transitions, causing "use of closed network connection" errors. Implemented file descriptor duplication using `unix.Dup` during bind initialization to gracefully persist the host-socket context across interface transitions and allow clean exit synchronization. - **Profile Configuration**: Implemented `handleProfileConfigure` in `internal/cli/cli.go` to launch the default system `$EDITOR` (falling back to `vi`) on a profile, satisfying the documentation's requirements. - **Hermetic Testing Polish**: - Created `dns_helpers.go` providing a `MockDNSServer` packet probe. - Added E2E tests for unprivileged DNS resolution, data-plane UDP handshake transmission, and 3-way DNS precedence routing. - Refactored `TestNamespaceLifecycleAutomation`, `TestConfigPropagation`, and `TestMTUFragmentation` to use default profile fallbacks, fixing failing stats on missing profiles. - Resolved all `golangci-lint` and `go fmt` warnings to maintain a completely clean static analysis pipeline.
2026-05-29feat: implement userspace wireguard data-path and unprivileged host fd-passingJames O'Doherty
- Implement complete rootless network namespace bootstrap via C launcher using unshare(CLONE_NEWUSER | CLONE_NEWNS | CLONE_NEWNET). - Resolve unprivileged network isolation blackhole via host-socket preservation (FD passing): open client UDP sockets on the host pre-isolation, clear O_CLOEXEC, and ingest them via custom `FDBind` inside the sandbox. - Implement isolated routing table automation over `tun0` (addresses, MTU, default routes). - Implement persistent, multi-process namespace sharing and joining using reference-counted PID files and the setns system call. - Write robust, self-contained E2E data plane test suites in `tests/e2e/e2e_test.go` using a mock UDP listener. - Update project documentation (`README.md` and `AGENTS.md`) to reflect completed milestones. - Ensure 100% test passing rate and zero lint/staticcheck warnings.
