Patrick O'Doherty	1535d0feca	safeweb: move http.Serve for HTTP redirects into lib (#11592) ... Refactor the interaction between caller/library when establishing the HTTP to HTTPS redirects by moving the call to http.Serve into safeweb. This makes linting for other uses of http.Serve easier without having to account for false positives created by the old interface.

Irbe Krumina	92ca770b8d	util/linuxfw: fix MSS clamping in nftables mode (#11588) ...

Joe Tsai	e2586bc674	logtail: always zstd compress with FastestCompression and LowMemory (#11583) ... This is based on empirical testing using actual logs data. FastestCompression only incurs a marginal <1% compression ratio hit for a 2.25x reduction in memory use for small payloads (which are common if log uploads happen at a decently high frequency). The memory savings for large payloads is much lower (less than 1.1x reduction). LowMemory only incurs a marginal <5% hit on performance for a 1.6-2.0x reduction in memory use for small or large payloads. The memory gains for both settings justifies the loss of benefits, which are arguably minimal. tailscale/corp#18514 Signed-off-by: Joe Tsai <joetsai@digital-static.net>	7 months ago

Irbe Krumina	5fb721d4ad	util/linuxfw,wgengine/router: skip IPv6 firewall configuration in partial iptables mode (#11546) ... We have hosts that support IPv6, but not IPv6 firewall configuration in iptables mode. We also have hosts that have some support for IPv6 firewall configuration in iptables mode, but do not have iptables filter table.

Irbe Krumina	9e2f58f846	cmd/{k8s-nameserver,k8s-operator},k8s-operator: add a kube nameserver, make operator deploy it (#11017) ... * cmd/k8s-nameserver,k8s-operator: add a nameserver that can resolve ts.net DNS names in cluster. Adds a simple nameserver that can respond to A record queries for ts.net DNS names. It can respond to queries from in-memory records, populated from a ConfigMap mounted at /config. It dynamically updates its records as the ConfigMap contents changes. It will respond with NXDOMAIN to queries for any other record types (AAAA to be implemented in the future). It can respond to queries over UDP or TCP. It runs a miekg/dns DNS server with a single registered handler for ts.net domain names. Queries for other domain names will be refused. The intended use of this is: 1) to allow non-tailnet cluster workloads to talk to HTTPS tailnet services exposed via Tailscale operator egress over HTTPS 2) to allow non-tailnet cluster workloads to talk to workloads in the same cluster that have been exposed to tailnet over their MagicDNS names but on their cluster IPs. Updates tailscale/tailscale#10499 Signed-off-by: Irbe Krumina <irbe@tailscale.com> * cmd/k8s-operator/deploy/crds,k8s-operator: add DNSConfig CustomResource Definition DNSConfig CRD can be used to configure the operator to deploy kube nameserver (./cmd/k8s-nameserver) to cluster.

Patrick O'Doherty	8f27520633	safeweb: init (#11467) ... Updates https://github.com/tailscale/corp/issues/8027 Safeweb is a wrapper around http.Server & tsnet that encodes some application security defaults. Safeweb asks developers to split their HTTP routes into two http.ServeMuxs for serving browser and API-facing endpoints repsectively. It then wraps these HTTP routes with the context-appropriate security controls. safeweb.Server#Serve will serve the HTTP muxes over the provided listener. Caller are responsible for creating and tearing down their application's listeners. Applications being served over HTTPS that wish to implement HTTP redirects can use the Server#HTTPRedirect handler to do so. Signed-off-by: Patrick O'Doherty <patrick@tailscale.com>	7 months ago

Brad Fitzpatrick	7b34154df2	all: deprecate Node.Capabilities (more), remove PeerChange.Capabilities [capver 89] ... First we had Capabilities []string. Then https://tailscale.com/blog/acl-grants (#4217) brought CapMap, a superset of Capabilities. Except we never really finished the transition inside the codebase to go all-in on CapMap. This does so. Notably, this coverts Capabilities on the wire early to CapMap internally so the code can only deal in CapMap, even against an old control server. In the process, this removes PeerChange.Capabilities support, which no known control plane sent anyway. They can and should use PeerChange.CapMap instead.

Brad Fitzpatrick	8444937c89	control/controlclient: fix panic regression from earlier load balancer hint header ... In the recent 20e9f3369 we made HealthChangeRequest machine requests include a NodeKey, as it was the oddball machine request that didn't include one. Unfortunately, that code was sometimes being called (at least in some of our integration tests) without a node key due to its registration with health.RegisterWatcher(direct.ReportHealthChange). Fortunately tests in corp caught this before we cut a release. It's possible this only affects this particular integration test's environment, but still worth fixing.

Joe Tsai	85febda86d	all: use zstdframe where sensible (#11491) ... Use the zstdframe package where sensible instead of plumbing around our own zstd.Encoder just for stateless operations. This causes logtail to have a dependency on zstd, but that's arguably okay since zstd support is implicit to the protocol between a client and the logging service. Also, virtually every caller to logger.NewLogger was manually setting up a zstd.Encoder anyways, meaning that zstd was functionally always a dependency.
