* [client] Reuse the profile's account for iOS SSO logins

Android reads the profile's stored account and passes it as the OIDC
login_hint, and records it again after a successful login. iOS did neither: it
called GetOAuthFlow with an empty hint, so a re-login was resolved by whatever
session the browser's cookie jar held rather than by the account the profile
belongs to. With a non-ephemeral browser session that is the wrong account as
soon as more than one is signed in.

Mirror client/android/login.go: hint from mobile.ReadProfileEmail before the
flow, mobile.WriteProfileEmail after Login succeeds. Storing after Login and
not before keeps a rejected token from leaving a hint that points at an
account which cannot be used.

* [client] Persist the account email on tvOS and on the device flow

Two paths left a profile with no account bound, so every later login went out
without a login_hint — the case this change exists to remove.

WriteProfileEmail went through util.WriteJsonWithRestrictedPermission, which
writes a temp file and renames it over the target. The tvOS App Group sandbox
blocks exactly that, which is why the config sitting next to this file is
written with DirectWriteOutConfig. On tvOS the email write therefore failed and
was dropped with a warning. Use DirectWriteJson: the file is rewritten whole
from a single key, so the only thing atomicity buys here is surviving a crash
mid-write, and a torn file reads back as "no email" and is replaced by the next
login.

The device authorization flow never populated TokenInfo.Email, unlike the PKCE
flow, so a client driven through it — Android TV and tvOS — bound no account at
all. Parse the ID token there too.

* [client] Report a failed close from DirectWriteJson

The deferred close assigned its error to err, but the return value was not
named, so the assignment went nowhere: a close that failed was logged and the
function still returned nil. The write is only durable once the file closes
cleanly, so every caller — the management config, the profile configs and the
profile account email — could be told the data landed when it had not.

Name the return so the assignment does what its shape always intended, and
report the failure once. When the body succeeded the close error is returned and
the caller logs it. When the body already failed, that error is the one that
explains the failure and is what the caller gets, which leaves the deferred log
as the only place the close failure can surface — at debug, per the logging
rules for close errors on writes.

🤖 NetBird Agent Network (Beta)

Identity-aware access control for AI agents — keyless access to LLM APIs and private resources over the encrypted NetBird tunnel. See agent-network/ or read the docs at netbird.ai.

NetBird combines a configuration-free peer-to-peer private network and a centralized access control system in a single platform, making it easy to create secure private networks for your organization or home.

Connect. NetBird creates a WireGuard-based overlay network that automatically connects your machines over an encrypted tunnel, leaving behind the hassle of opening ports, complex firewall rules, VPN gateways, and so forth.

Secure. NetBird enables secure remote access by applying granular access policies while allowing you to manage them intuitively from a single place. Works universally on any infrastructure.

Quickstart with NetBird Cloud

Quickstart with self-hosted NetBird

This is the quickest way to try self-hosted NetBird. It should take around 5 minutes to get started if you already have a public domain and a VM. Follow the Advanced guide with a custom identity provider for installations with different IdPs.

Infrastructure requirements:

  • A Linux VM with at least 1 CPU and 2 GB of memory.
  • The VM should be publicly accessible on TCP ports 80 and 443 and UDP port 3478.
  • A public domain name pointing to the VM.

Software requirements:

Steps

  • Download and run the installation script:
export NETBIRD_DOMAIN=netbird.example.com; curl -fsSL https://github.com/netbirdio/netbird/releases/latest/download/getting-started.sh | bash

A bit on NetBird internals

  • Every machine in the network runs the NetBird agent, which manages WireGuard.
  • Every agent connects to the Management Service, which holds network state, manages peer IPs, and distributes updates to agents.
  • Agents use ICE (via pion/ice) to discover connection candidates for peer-to-peer connections.
  • Candidates are discovered with the help of STUN servers.
  • Agents negotiate a connection through the Signal Service, exchanging end-to-end encrypted messages with candidates.
  • When NAT traversal fails (e.g. mobile carrier-grade NAT) and a direct p2p connection isn't possible, the system falls back to a Relay Service and a secure WireGuard tunnel is established through it.

Support acknowledgement

In November 2022, NetBird joined the StartUpSecure program sponsored by the Federal Ministry of Education and Research of the Federal Republic of Germany. Together with the CISPA Helmholtz Center for Information Security, NetBird brings security best practices and simplicity to private networking.
