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.

Joe Tsai	d4bfe34ba7	util/zstdframe: add package for stateless zstd compression (#11481) ... The Go zstd package is not friendly for stateless zstd compression. Passing around multiple zstd.Encoder just for stateless compression is a waste of memory since the memory is never freed and seldom used if no compression operations are happening. For performance, we pool the relevant Encoder/Decoder with the specific options set. Functionally, this package is a wrapper over the Go zstd package with a more ergonomic API for stateless operations. This package can be used to cleanup various pre-existing zstd.Encoder pools or one-off handlers spread throughout our codebases.

We can also see that LowMemory takes effect where the pooled coder object references less memory than other cases. We can see that the pooling is taking effect as there are 0 amortized allocations.

In particular, coders can be freed by the GC when not in use. Coders can be shared throughout the program if they use this package instead of multiple independent pools doing the same thing. The allocations are unrelated to pooling as they're caused by the spawning of goroutines.

Andrea Gottardo	6288c9b41e	version/prop: remove IsMacAppSandboxEnabled (#11461) ... Fixes tailscale/corp#18441 For a few days, IsMacAppStore() has been returning `false` on App Store builds (IPN-macOS target in Xcode). I regressed this in #11369 by introducing logic to detect the sandbox by checking for the APP_SANDBOX_CONTAINER_ID environment variable. I thought that was a more robust approach instead of checking the name of the executable. However, it appears that on recent macOS versions this environment variable is no longer getting set, so we should go back to the previous logic that checks for the executable path, or HOME containing references to macsys. This PR also adds additional checks to the logic by also checking XPC_SERVICE_NAME in addition to HOME where possible. That environment variable is set inside the network extension, either macos or macsys and is good to look at if for any reason HOME is not set.	8 months ago

Andrew Dunham	7429e8912a	wgengine/netstack: fix bug with duplicate SYN packets in client limit ... This fixes a bug that was introduced in #11258 where the handling of the per-client limit didn't properly account for the fact that the gVisor TCP forwarder will return 'true' to indicate that it's handled a duplicate SYN packet, but not launch the handler goroutine. In such a case, we neither decremented our per-client limit in the wrapper function, nor did we do so in the handler function, leading to our per-client limit table slowly filling up without bound. Fix this by doing the same duplicate-tracking logic that the TCP forwarder does so we can detect such cases and appropriately decrement our in-flight counter.
