salman aljammaz	25a7204bb4	wgengine,ipn,cmd/tailscale: add size option to ping (#8739 ) This adds the capability to pad disco ping message payloads to reach a specified size. It also plumbs it through to the tailscale ping -size flag. Disco pings used for actual endpoint discovery do not use this yet. Updates #311.

Aaron Klotz	37925b3e7a	go.mod, cmd/tailscaled, ipn/localapi, util/osdiag, util/winutil, util/winutil/authenticode: add Windows module list to OS-specific logs that are written upon bugreport * We update wingoes to pick up new version information functionality (See pe/version.go in the https://github.com/dblohm7/wingoes repo); * We move the existing LogSupportInfo code (including necessary syscall stubs) out of util/winutil into a new package, util/osdiag, and implement the public LogSupportInfo function may be implemented for other platforms as needed; * We add a new reason argument to LogSupportInfo and wire that into localapi's bugreport implementation; * We add module information to the Windows implementation of LogSupportInfo when reason indicates a bugreport. We enumerate all loaded modules in our process, and for each one we gather debug, authenticode signature, and version information.

David Anderson	ed46442cb1	client/tailscale/apitype: document never-nil property of WhoIsResponse Every time I use WhoIsResponse I end up writing mildly irritating nil-checking for both Node and UserProfile, but it turns out our code guarantees that both are non-nil in successful whois responses.

Andrew Lytvynov	c1ecae13ab	ipn/{ipnlocal,localapi}: actually renew certs before expiry (#8731 ) While our `shouldStartDomainRenewal` check is correct, `getCertPEM` would always bail if the existing cert is not expired. Add the same `shouldStartDomainRenewal` check to `getCertPEM` to make it proceed with renewal when existing certs are still valid but should be renewed. The extra check is expensive (ARI request towards LetsEncrypt), so cache the last check result for 1hr to not degrade `tailscale serve` performance. Also, asynchronous renewal is great for `tailscale serve` but confusing for `tailscale cert`. Add an explicit flag to `GetCertPEM` to force a synchronous renewal for `tailscale cert`.

Maisem Ali	1ecc16da5f	tailcfg,ipn/ipnlocal,wgengine: add values to PeerCapabilities Define PeerCapabilty and PeerCapMap as the new way of sending down inter-peer capability information. Previously, this was unstructured and you could only send down strings which got too limiting for certain usecases. Instead add the ability to send down raw JSON messages that are opaque to Tailscale but provide the applications to define them however they wish. Also update accessors to use the new values.

Dominic Black	570cb018da	ipn/localapi: require only read permission for WatchIPNBus (#7798 ) Allow calls to `WatchIPNBus` to be permformed by clients with Readonly permissions. This brings it in line with the permissions required for `Status`, which also exposes the similar information. This allows clients to get realtime updates about the tailnet in their own applications, without needing to actively poll the `Status` endpoint.

Mihai Parparita	7330aa593e	all: avoid repeated default interface lookups On some platforms (notably macOS and iOS) we look up the default interface to bind outgoing connections to. This is both duplicated work and results in logspam when the default interface is not available (i.e. when a phone has no connectivity, we log an error and thus cause more things that we will try to upload and fail). Fixed by passing around a netmon.Monitor to more places, so that we can use its cached interface state. Fixes #7850 Updates #7621 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	4722f7e322	all: move network monitoring from wgengine/monitor to net/netmon We're using it in more and more places, and it's not really specific to our use of Wireguard (and does more just link/interface monitoring). Also removes the separate interface we had for it in sockstats -- it's a small enough package (we already pull in all of its dependencies via other paths) that it's not worth the extra complexity.

Will Norris	57a008a1e1	all: pass log IDs as the proper type rather than strings This change focuses on the backend log ID, which is the mostly commonly used in the client.

Mihai Parparita	4973956419	ipn/ipnlocal: add /reset-auth LocalAPI endpoint The iOS has a command to reset the persisted state of the app, but it was doing its own direct keychain manipulation. This proved to be brittle (since we changed how preferences are stored with #6022), so we instead add a LocalAPI endpoint to do do this, which can be updated in tandem. This clears the same state as the iOS implementation (tailscale/corp#3186), that is the machine key and preferences (which includes the node key). Notably this does not clear the logtail ID, so that logs from the device still end up in the same place. Updates tailscale/corp#8923 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago

salman	eec734a578	ipn/{ipnlocal,localapi}: ensure watcher is installed before /watch-ipn-bus/ responds with 200 This change delays the first flush in the /watch-ipn-bus/ handler until after the watcher has been successfully installed on the IPN bus. It does this by adding a new onWatchAdded callback to LocalBackend.WatchNotifications(). Without this, the endpoint returns a 200 almost immediatly, and only then installs a watcher for IPN events. This means there's a small window where events could be missed by clients after calling WatchIPNBus(). Fixes tailscale/corp#8594. Signed-off-by: salman <salman@tailscale.com>	2 years ago
