Nothing in CI compiles the files behind //go:build android or //go:build ios.
The android bridge builds 7 of its 23 files on linux and skips client.go; the
iOS SDK is not built at all. The linter matrix picks a GOOS by picking a runner
OS, so it loads the same file set as the host build and never sees them either.
A type error in client/android/client.go therefore passes every check on its
PR, merges, and is discovered by netbirdio/android-client after sync-tag.yml
fires trigger_android_bump on the release tag.
The new Mobile workflow cross-compiles ./client/android/... for the GOARCH
values gomobile ships and ./client/ios/..., and vets the android bridge. The
new Android and iOS lint jobs run golangci-lint with GOOS/GOARCH in the job
env. No NDK, Xcode or gomobile is needed: these are library packages, so the
compiler type-checks them without a link step, and the dependency graph drags
in the android/ios-tagged files across client/iface, client/internal/dns and
client/internal/routemanager with them.
Linting those files for the first time surfaces one gosec G101 on the SSH
password-required marker. It is a sentinel string the Java side matches on,
not a credential, so it is suppressed at the declaration.
Both sides extended the OAuth flow entry points: main threads a login hint
through GetOAuthFlow/NewOAuthFlow, this branch threads a sessionExtend flag.
The merged signatures carry both.
client/android/login.go keeps main's structure — the hint reaches the flow
through GetOAuthFlow rather than a loginHintSetter assertion, profile email
helpers live in client/mobile, and runOAuthFlow is the shared driver — with
this branch's sessionExtend plumbing and wrong-account retry layered on top.
The branch's runInteractiveFlow is dropped in favour of runOAuthFlow.
client/android/ssh_client.go is new from main and merged without conflict,
but calls NewOAuthFlow; SSH login is a fresh login, so it passes false.
management.pb.go regenerated with the pinned protoc-gen-go v1.26 from
generate.sh. The .proto merged cleanly: main's LazyState and proxy_embedded
are disjoint from this branch's SessionExtend field.
Adds an SSHClient gomobile binding so the Android app can run an SSH session over the tunnel with a PTY, exposed through a listener interface for the in-app terminal.
Server type is auto-detected from the SSH banner, which selects the auth path: JWT device-code flow, NetBird key, or a regular server (NetBird key first, then password). Host keys are verified against the peer registry for NetBird servers and trust-on-first-use for regular ones.
