Will Norris	b3cc719add	cmd/nginx-auth: allow use of shared nodes ... When sharing nodes, the name of the sharee node is not exposed (instead it is hardcoded to "device-of-shared-to-user"), which means that we can't determine the tailnet of that node. Don't immediately fail when that happens, since it only matters if "Expected-Tailnet" is used. Signed-off-by: Will Norris <will@tailscale.com>	2 years ago
Joe Tsai	3fc8683585	util/deephash: expand fast-path capabilities (#5404) ... Add support for maps and interfaces to the fast path. Add cycle-detection to the pointer handling logic. This logic is mostly copied from the slow path. A future commit will delete the slow path once the fast path never falls back to the slow path. Performance: name old time/op new time/op delta Hash-24 18.5µs ± 1% 14.9µs ± 2% -19.52% (p=0.000 n=10+10) HashPacketFilter-24 2.54µs ± 1% 2.60µs ± 1% +2.19% (p=0.000 n=10+10) HashMapAcyclic-24 31.6µs ± 1% 30.5µs ± 1% -3.42% (p=0.000 n=9+8) TailcfgNode-24 1.44µs ± 2% 1.43µs ± 1% ~ (p=0.171 n=10+10) HashArray-24 324ns ± 1% 324ns ± 2% ~ (p=0.425 n=9+9) The additional cycle detection logic doesn't incur much slow down since it only activates if a type is recursive, which does not apply for any of the types that we care about. There is a notable performance boost since we switch from the fath path to the slow path less often. Most notably, a struct with a field that could not be handled by the fast path would previously cause the entire struct to go through the slow path.

Mihai Parparita	78b90c3685	cmd/tsconnect: stop writing build artifacts into src/ ... We can't write to src/ when tsconnect is used a dependency in another repo (see also b763a12331). We therefore need to switch from writing to src/ to using esbuild plugins to handle the requests for wasm_exec.js (the Go JS runtime for Wasm) and the Wasm build of the Go module. This has the benefit of allowing Go/Wasm changes to be picked up without restarting the server when in dev mode (Go compilation is fast enough that we can do this on every request, CSS compilation continues to be the long pole).

Joe Tsai	d32700c7b2	util/deephash: specialize for netip.Addr and drop AppendTo support (#5402) ... There are 5 types that we care about that implement AppendTo: key.DiscoPublic key.NodePublic netip.Prefix netipx.IPRange netip.Addr The key types are thin wrappers around [32]byte and are memory hashable. The netip.Prefix and netipx.IPRange types are thin wrappers over netip.Addr and are hashable by default if netip.Addr is hashable. The netip.Addr type is the only one with a complex structure where the default behavior of deephash does not hash it correctly due to the presence of the intern.Value type. Drop support for AppendTo and instead add specialized hashing for netip.Addr that would be semantically equivalent to == on the netip.Addr values. The AppendTo support was already broken prior to this change. It was fully removed (intentionally or not) in #4870. It was partially restored in #4858 for the fast path, but still broken in the slow path. Just drop support for it altogether. This does mean we lack any ability for types to self-hash themselves. In the future we can add support for types that implement: interface { DeepHash() Sum } Test and fuzz cases were added for the relevant types that used to rely on the AppendTo method. FuzzAddr has been executed on 1 billion samples without issues. Signed-off-by: Joe Tsai joetsai@digital-static.net	2 years ago

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.
