Tom DNetto	79905a1162	tka: make storage a parameter rather than an Authority struct member ... Updates #5435 Based on the discussion in #5435, we can better support transactional data models by making the underlying storage layer a parameter (which can be specialized for the request) rather than a long-lived member of Authority. Now that Authority is just an instantaneous snapshot of state, we can do things like provide idempotent methods and make it cloneable, too. Signed-off-by: Tom DNetto <tom@tailscale.com>	2 years ago

Tom DNetto	f580f4484f	tka: move disablement logic out-of-band from AUMs ... It doesn't make a ton of sense for disablement to be communicated as an AUM, because any failure in the AUM or chain mechanism will mean disablement wont function. Instead, tracking of the disablement secrets remains inside the state machine, but actual disablement and communication of the disablement secret is done by the caller.

Mihai Parparita	7a5cf39d0d	ipn/ipnlocal: fix Taildrop not returning any sharing targets ... The CapabilityFileSharingTarget capability added by eb32847d85 is meant to control the ability to share with nodes not owned by the current user, not to restrict all sharing (the coordination server is not currently populating the capability at all) Fixes tailscale/corp#6669 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago

Mihai Parparita	1a093ef482	cmd/tsconnect: extract NPM package for reusing in other projects ... `src/` is broken up into several subdirectories: - `lib/` and `types`/ for shared code and type definitions (more code will be moved here) - `app/` for the existing Preact-app - `pkg/` for the new NPM package A new `build-pkg` esbuild-based command is added to generate the files for the NPM package. To generate type definitions (something that esbuild does not do), we set up `dts-bundle-generator`. Includes additional cleanups to the Wasm type definitions (we switch to string literals for enums, since exported const enums are hard to use via packages). Also allows the control URL to be set a runtime (in addition to the current build option), so that we don't have to rebuild the package for dev vs. prod use.

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

While we rename the package as hashx in this commit, a subsequent commit will move the sha256x package to hashx. This is done separately to avoid confusing git.

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.
