Brad Fitzpatrick	ace2faf7ec	cmd/tailscale: make debug profiling output - mean stdout ... Because the macOS CLI runs in the sandbox, including the filesystem, so users would be confused that -cpu-profile=prof.cpu succeeds but doesn't write to their current directory, but rather in some random Library/Containers directory somewhere on the machine (which varies depending on the Mac build type: App Store vs System Extension) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	efb84ca60d	ipn/localapi, cmd/tailscale: add CPU & memory profile support, debug command ... This was already possible on Linux if you ran tailscaled with --debug (which runs net/http/pprof), but it requires the user have the Go toolchain around. Also, it wasn't possible on macOS, as there's no way to run the IPNExtension with a debug server (it doesn't run tailscaled). And on Windows it's super tedious: beyond what users want to do or what we want to explain. Instead, put it in "tailscale debug" so it works and works the same on all platforms. Then we can ask users to run it when we're debugging something and they can email us the output files. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Denton Gentry	27bc4e744c	cmd/tailscale/web: support TLS from env vars. ... pfSense stores its SSL certificate and key in the PHP config.

Aaron Klotz	9ebb5d4205	ipn, paths: ensure that the state directory for Windows has the correct perms ... ProgramData has a permissive ACL. For us to safely store machine-wide state information, we must set a more restrictive ACL on our state directory. We set the ACL so that only talescaled's user (ie, LocalSystem) and the Administrators group may access our directory. We must include Administrators to ensure that logs continue to be easily accessible; omitting that group would force users to use special tools to log in interactively as LocalSystem, which is not ideal. (Note that the ACL we apply matches the ACL that was used for LocalSystem's AppData\Local). There are two cases where we need to reset perms: One is during migration from the old location to the new. The second case is for clean installations where we are creating the file store for the first time. Updates #2856 Signed-off-by: Aaron Klotz <aaron@tailscale.com>	3 years ago

Joe Tsai	d145c594ad	util/deephash: improve cycle detection (#2470) ... The previous algorithm used a map of all visited pointers. The strength of this approach is that it quickly prunes any nodes that we have ever visited before. The detriment of the approach is that pruning is heavily dependent on the order that pointers were visited. This is especially relevant for hashing a map where map entries are visited in a non-deterministic manner, which would cause the map hash to be non-deterministic (which defeats the point of a hash). This new algorithm uses a stack of all visited pointers, similar to how github.com/google/go-cmp performs cycle detection. When we visit a pointer, we push it onto the stack, and when we leave a pointer, we pop it from the stack. Before visiting a pointer, we first check whether the pointer exists anywhere in the stack. If yes, then we prune the node. The detriment of this approach is that we may hash a node more often than before since we do not prune as aggressively. The set of visited pointers up until any node is only the path of nodes up to that node and not any other pointers that may have been visited elsewhere. This provides us deterministic hashing regardless of visit order. We can now delete hashMapFallback and associated complexity, which only exists because the previous approach was non-deterministic in the presence of cycles. This fixes a failure of the old algorithm where obviously different values are treated as equal because the pruning was too aggresive. See https://github.com/tailscale/tailscale/issues/2443#issuecomment-883653534 The new algorithm is slightly slower since it prunes less aggresively: name old time/op new time/op delta Hash-8 66.1µs ± 1% 68.8µs ± 1% +4.09% (p=0.000 n=19+19) HashMapAcyclic-8 63.0µs ± 1% 62.5µs ± 1% -0.76% (p=0.000 n=18+19) TailcfgNode-8 9.79µs ± 2% 9.88µs ± 1% +0.95% (p=0.000 n=19+17) HashArray-8 643ns ± 1% 653ns ± 1% +1.64% (p=0.000 n=19+19) However, a slower but more correct algorithm seems more favorable than a faster but incorrect algorithm.

Brad Fitzpatrick	7f7a81e5ae	cmd/tailscaled: add func to create ipnserver.Opts ... To unify the Windows service and non-service/non-Windows paths a bit. And provides a way to make Linux act like Windows for testing. (notably, for testing the fix to #2137) One perhaps visible change of this is that tailscaled.exe when run in cmd.exe/powershell (not as a Windows Service) no longer uses the "_daemon" autostart key. But in addition to being naturally what falls out of this change, that's also what Windows users would likely want, as otherwise the unattended mode user is ignored when the "_daemon" autostart key is specified. Notably, this would let people debug what their normally-run-as-a-service tailscaled is doing, even when they're running in Unattended Mode.

Denton Gentry	e28bc49e5f	netns_linux: remove special handling for tests. ... With netns handling localhost now, existing tests no longer need special handling. The tests set up their connections to localhost, and the connections work without fuss. Remove the special handling for tests. Also remove the hostinfo.TestCase support, since this was the only use of it. It can be added back later if really needed, but it would be better to try to make tests work without special cases.

Denton Gentry	d2480fd508	net/netns: support !CAP_NET_ADMIN ... netns_linux checked whether "ip rule" could run to determine whether to use SO_MARK for network namespacing. However in Linux environments which lack CAP_NET_ADMIN, such as various container runtimes, the "ip rule" command succeeds but SO_MARK fails due to lack of permission. SO_BINDTODEVICE would work in these environments, but isn't tried. In addition to running "ip rule" check directly whether SO_MARK works or not. Among others, this allows Microsoft Azure App Service and AWS App Runner to work. Signed-off-by: Denton Gentry <dgentry@tailscale.com>	3 years ago
