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>	10 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.

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.

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.

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>	12 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
