Brad Fitzpatrick	766ea96adf	cmd/tailscaled: enable hybrid netstack mode on openbsd too Apparently OpenBSD can forward packets with manual configuration, https://github.com/tailscale/tailscale/issues/2498#issuecomment-1114216999 But this makes it work by default. People doing things by hand can set TS_DEBUG_WRAP_NETSTACK=0 in the environment.

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.

Joe Tsai	1f7479466e	util/deephash: use sha256x (#5339 ) Switch deephash to use sha256x.Hash. We add sha256x.HashString to efficiently hash a string. It uses unsafe under the hood to convert a string to a []byte. We also modify sha256x.Hash to export the underlying hash.Hash for testing purposes so that we can intercept all hash.Hash calls.

Joe Tsai	77a92f326d	util/deephash: avoid using sync.Pool for reflect.MapIter (#5333 ) In Go 1.19, the reflect.Value.MapRange method uses "function outlining" so that the allocation of reflect.MapIter is inlinable by the caller.

Joe Tsai	76b0e578c5	util/sha256x: new package (#5337 ) The hash.Hash provided by sha256.New is much more efficient if we always provide it with data a multiple of the block size.

Joe Tsai	539c5e44c5	util/deephash: always keep values addressable (#5328 ) The logic of deephash is both simpler and easier to reason about if values are always addressable. In Go, the composite kinds are slices, arrays, maps, structs, interfaces, pointers, channels, and functions, where we define "composite" as a Go value that encapsulates some other Go value (e.g., a map is a collection of key-value entries). In the cases of pointers and slices, the sub-values are always addressable. In the cases of arrays and structs, the sub-values are always addressable if and only if the parent value is addressable. In the case of maps and interfaces, the sub-values are never addressable. To make them addressable, we need to copy them onto the heap. For the purposes of deephash, we do not care about channels and functions. For all non-composite kinds (e.g., strings and ints), they are only addressable if obtained from one of the composite kinds that produce addressable values (i.e., pointers, slices, addressable arrays, and addressable structs). A non-addressible, non-composite kind can be made addressable by allocating it on the heap, obtaining a pointer to it, and dereferencing it. Thus, if we can ensure that values are addressable at the entry points, and shallow copy sub-values whenever we encounter an interface or map, then we can ensure that all values are always addressable and assume such property throughout all the logic.

Mihai Parparita	ab159f748b	cmd/tsconnect: switch UI to Preact Reduces the amount of boilerplate to render the UI and makes it easier to respond to state changes (e.g. machine getting authorized, netmap changing, etc.) Preact adds ~13K to our bundle size (5K after Brotli) thus is a neglibible size contribution. We mitigate the delay in rendering the UI by having a static placeholder in the HTML.

David Crawshaw	15b8665787	tka: stable text representation of AUMHash This makes debugging easier, you can pass an AUMHash to a printf and get a string that is easy to debug. Also rearrange how directories/files work in the FS store: use the first two characters of the string representation as the prefix directory, and use the entire AUMHash string as the file name. This is again to aid debugging: you can `ls` a directory and line up what prints out easily with what you get from a printf in debug code.
