Aaron Klotz	73b8968404	ipn/ipnlocal: ensure Persist information is saved to server mode start state ... Numerous issues have been filed concerning an inability to install and run Tailscale headlessly in unattended mode, particularly after rebooting. The server mode `Prefs` stored in `server-state.conf` were not being updated with `Persist` state once the node had been succesfully logged in. Users have been working around this by finagling with the GUI to make it force a state rewrite. This patch makes that unnecessary by ensuring the required server mode state is updated when prefs are updated by the control client.

Brad Fitzpatrick	9be8d15979	ipn/localapi: refactor some cert code in prep for a move ... I want to move the guts (after the HTTP layer) of the certificate fetching into the ipnlocal package, out of localapi. As prep, refactor a bit: * add a method to do the fetch-from-cert-or-as-needed-with-refresh, rather than doing it in the HTTP hander * convert two methods to funcs, taking the one extra field (LocalBackend) then needed from their method receiver. One of the methods needed nothing from its receiver. This will make a future change easier to reason about.

Tom DNetto	a515fc517b	ipn/ipnlocal: make tkaSyncIfNeeded exclusive with a mutex ... Running corp/ipn#TestNetworkLockE2E has a 1/300 chance of failing, and deskchecking suggests thats whats happening are two netmaps are racing each other to be processed through tkaSyncIfNeededLocked. This happens in the first place because we release b.mu during network RPCs. To fix this, we make the tka sync logic an exclusive section, so two netmaps will need to wait for tka sync to complete serially (which is what we would want anyway, as the second run through probably wont need to sync).

Brad Fitzpatrick	45a3de14a6	cmd/tailscaled, tailcfg, hostinfo: add flag to disable logging + support ... As noted in #5617, our documented method of blocking log.tailscale.io DNS no longer works due to bootstrap DNS. Instead, provide an explicit flag (--no-logs-no-support) and/or env variable (TS_NO_LOGS_NO_SUPPORT=true) to explicitly disable logcatcher uploads. It also sets a bit on Hostinfo to say that the node is in that mode so we can end any support tickets from such nodes more quickly. This does not yet provide an easy mechanism for users on some platforms (such as Windows, macOS, Synology) to set flags/env. On Linux you'd used /etc/default/tailscaled typically. Making it easier to set flags for other platforms is tracked in #5114.

Mihai Parparita	7a5cf39d0d	ipn/ipnlocal: fix Taildrop not returning any sharing targets ... The CapabilityFileSharingTarget capability added by eb32847d85 is meant to control the ability to share with nodes not owned by the current user, not to restrict all sharing (the coordination server is not currently populating the capability at all) Fixes tailscale/corp#6669 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago

Joe Tsai	32a1a3d1c0	util/deephash: avoid variadic argument for Update (#5372) ... Hashing []any is slow since hashing of interfaces is slow. Hashing of interfaces is slow since we pessimistically assume that cycles can occur through them and start cycle tracking. Drop the variadic signature of Update and fix callers to pass in an anonymous struct so that we are hashing concrete types near the root of the value tree.

Tom DNetto	4001d0bf25	assorted: plumb tka initialization & network-lock key into tailscaled ... - A network-lock key is generated if it doesn't already exist, and stored in the StateStore. The public component is communicated to control during registration. - If TKA state exists on the filesystem, a tailnet key authority is initialized (but nothing is done with it for now).
