Fran Bull	e06862b8d8	appc: log how often routeInfo is stored So that we have some debugging info if users have trouble with storing the routeInfo. Updates #11008 Signed-off-by: Fran Bull <fran@tailscale.com>	6 months ago
Fran Bull	6a0fbacc28	appc: setting AdvertiseRoutes explicitly discards app connector routes This fixes bugs where after using the cli to set AdvertiseRoutes users were finding that they had to restart tailscaled before the app connector would advertise previously learned routes again. And seems more in line with user expectations. Fixes #11006 Signed-off-by: Fran Bull <fran@tailscale.com>	7 months ago
Fran Bull	c27dc1ca31	appc: unadvertise routes when reconfiguring app connector If the controlknob to persist app connector routes is enabled, when reconfiguring an app connector unadvertise routes that are no longer relevant. Updates #11008 Signed-off-by: Fran Bull <fran@tailscale.com>	7 months ago
Fran Bull	fea2e73bc1	appc: write discovered domains to StateStore If the controlknob is on. This will allow us to remove discovered routes associated with a particular domain. Updates #11008 Signed-off-by: Fran Bull <fran@tailscale.com>	7 months ago
Fran Bull	1bd1b387b2	appc: add flag shouldStoreRoutes and controlknob for it When an app connector is reconfigured and domains to route are removed, we would like to no longer advertise routes that were discovered for those domains. In order to do this we plan to store which routes were discovered for which domains. Add a controlknob so that we can enable/disable the new behavior.

Fran Bull	79836e7bfd	appc: add RouteInfo struct and persist it to StateStore Lays the groundwork for the ability to persist app connectors discovered routes, which will allow us to stop advertising routes for a domain if the app connector no longer monitors that domain. Updates #11008 Signed-off-by: Fran Bull <fran@tailscale.com>	7 months ago
James Tucker	0f5e031133	appc: optimize dns response observation for large route tables Advertise DNS discovered addresses as a single preference update rather than one at a time. Sort the list of observed addresses and use binary search to consult the list. Updates tailscale/corp#16636 Signed-off-by: James Tucker <james@tailscale.com>	9 months ago
James Tucker	e1a4b89dbe	appc,ipn/ipnlocal: add app connector routes if any part of a CNAME chain is routed If any domain along a CNAME chain matches any of the routed domains, add routes for the discovered domains. Fixes tailscale/corp#16928 Signed-off-by: James Tucker <james@tailscale.com>	10 months ago
James Tucker	0e2cb76abe	appc: add test to ensure that individual IPs are not removed during route updates If control advised the connector to advertise a route that had already been discovered by DNS it would be incorrectly removed. Now those routes are preserved. Updates tailscale/corp#16833 Signed-off-by: James Tucker <james@tailscale.com>	10 months ago
Charlotte Brandhorst-Satzkorn	ce4553b988	appc,ipn/ipnlocal: optimize preference adjustments when routes update This change allows us to perform batch modification for new route advertisements and route removals. Additionally, we now handle the case where newly added routes are covered by existing ranges. This change also introduces a new appctest package that contains some shared functions used for testing. Updates tailscale/corp#16833 Signed-off-by: Charlotte Brandhorst-Satzkorn <charlotte@tailscale.com>	10 months ago
James Tucker	8250582fe6	ipn/ipnlocal: make app connector configuration concurrent If there are routes changes as a side effect of an app connector configuration update, the connector configuration may want to reenter a lock, so must be started asynchronously. Updates tailscale/corp#16833 Signed-off-by: James Tucker <james@tailscale.com>	10 months ago
James Tucker	24df1ef1ee	appc,ipn/ipnlocal,types/appctype: implement control provided routes Control can now send down a set of routes along with the domains, and the routes will be advertised, with any newly overlapped routes being removed to reduce the size of the routing table. Fixes tailscale/corp#16833 Signed-off-by: James Tucker <james@tailscale.com>	10 months ago
James Tucker	0957258f84	appc,ipn: prevent undesirable route advertisements Individual route advertisements that are covered by existing routes are no longer advertised. If an upstream returns 0.0.0.0, 127.x, and other common unwanted addresses those are also rejected. Updates #16425 Signed-off-by: James Tucker <james@tailscale.com>	11 months ago
James Tucker	245ddb157b	appc: fix DomainRoutes copy The non-referential copy destination doesn't extend the map contents, but also the read of a non-key is returning a zero value not bound to the map contents in any way. Updates tailscale/corp#15657 Signed-off-by: James Tucker <james@tailscale.com>	1 year ago
James Tucker	1a143963ec	appc: prevent duplication of wildcard entries on map updates Updates #15437 Signed-off-by: James Tucker <james@tailscale.com>	1 year ago
James Tucker	73de6a1a95	appc: add support for matching wildcard domains The app connector matches a configuration of "*.example.com" to mean any sub-domain of example.com. Updates #15437 Signed-off-by: James Tucker <james@tailscale.com>	1 year ago
Charlotte Brandhorst-Satzkorn	f937cb6794	tailcfg,ipn,appc: add c2n endpoint for appc domain routes This change introduces a c2n endpoint that returns a map of domains to a slice of resolved IP addresses for the domain. Fixes tailscale/corp#15657 Signed-off-by: Charlotte Brandhorst-Satzkorn <charlotte@tailscale.com>	1 year ago
James Tucker	f27b2cf569	appc,cmd/sniproxy,ipn/ipnlocal: split sniproxy configuration code out of appc The design changed during integration and testing, resulting in the earlier implementation growing in the appc package to be intended now only for the sniproxy implementation. That code is moved to it's final location, and the current App Connector code is now renamed. Updates tailscale/corp#15437 Signed-off-by: James Tucker <james@tailscale.com>	1 year ago
