Maisem Ali	3f4c5daa15	wgengine/netstack: remove SubnetRouterWrapper It was used when we only supported subnet routers on linux and would nil out the SubnetRoutes slice as no other router worked with it, but now we support subnet routers on ~all platforms. The field it was setting to nil is now only used for network logging and nowhere else, so keep the field but drop the SubnetRouterWrapper as it's not useful.

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.

James Tucker	24bac27632	util/rands: add Shuffle and Perm functions with on-stack RNG state The new math/rand/v2 package includes an m-local global random number generator that can not be reseeded by the user, which is suitable for most uses without the RNG pools we have in a number of areas of the code base. The new API still does not have an allocation-free way of performing a seeded operations, due to the long term compiler bug around interface parameter escapes, and the Source interface. This change introduces the two APIs that math/rand/v2 can not yet replace efficiently: seeded Perm() and Shuffle() operations. This implementation chooses to use the PCG random source from math/rand/v2, as with sufficient compiler optimization, this source should boil down to only two on-stack registers for random state under ideal conditions.

Aaron Klotz	855f79fad7	cmd/tailscaled, util/winutil: changes to process and token APIs in winutil This PR changes the internal getTokenInfo function to use generics. I also removed our own implementations for obtaining a token's user and primary group in favour of calling the ones now available in x/sys/windows. Furthermore, I added two new functions for working with tokens, logon session IDs, and Terminal Services / RDP session IDs. I modified our privilege enabling code to allow enabling of multiple privileges via one single function call. Finally, I added the ProcessImageName function and updated the code in tailscaled_windows.go to use that instead of directly calling the underlying API.

Aaron Klotz	47019ce1f1	cmd/tailscaled: pre-load wintun.dll using a fully-qualified path In corp PR #14970 I updated the installer to set a security mitigation that always forces system32 to the front of the Windows dynamic linker's search path. Unfortunately there are other products out there that, partying like it's 1995, drop their own, older version of wintun.dll into system32. Since we look there first, we end up loading that old version. We can fix this by preloading wintun using a fully-qualified path. When wintun-go then loads wintun, the dynamic linker will hand it the module that was previously loaded by us. Fixes #10023, #10025, #10052 Signed-off-by: Aaron Klotz <aaron@tailscale.com>	1 year ago

This will be used to run the new full management web client, which will only be accessible over Tailscale (with an extra auth check step over noise) from the daemon. This switch also allows us to run the web interface as a long-lived service in environments where the CLI version is restricted to CGI, allowing us to manage certain auth state in memory. ipn/ipnlocal/web is stubbed out in ipn/ipnlocal/web_stub for ios builds to satisfy ios restriction from adding "text/template" and "html/template" dependencies.

Aaron Klotz	95671b71a6	ipn, safesocket: use Windows token in LocalAPI On Windows, the idiomatic way to check access on a named pipe is for the server to impersonate the client on its current OS thread, perform access checks using the client's access token, and then revert the OS thread's access token back to its true self. The access token is a better representation of the client's rights than just a username/userid check, as it represents the client's effective rights at connection time, which might differ from their normal rights. This patch updates safesocket to do the aforementioned impersonation, extract the token handle, and then revert the impersonation. We retain the token handle for the remaining duration of the connection (the token continues to be valid even after we have reverted back to self). Since the token is a property of the connection, I changed ipnauth to wrap the concrete net.Conn to include the token. I then plumbed that change through ipnlocal, ipnserver, and localapi as necessary. I also added a PermitLocalAdmin flag to the localapi Handler which I intend to use for controlling access to a few new localapi endpoints intended for configuring auto-update.

Brad Fitzpatrick	343c0f1031	wgengine{,/netstack}: remove AddNetworkMapCallback from Engine interface It had exactly one user: netstack. Just have LocalBackend notify netstack when here's a new netmap instead, simplifying the bloated Engine interface that has grown a bunch of non-Engine-y things.

To repro, add this to tstest/integration: func TestFailInFewSeconds(t testing.T) { t.Parallel() time.Sleep(3 time.Second) os.Exit(1) t.Fatal("boom") } Those three seconds let the other parallel tests (with all their tailscaled child processes) start up and start running their tests, but then we violently os.Exit(1) the test driver and all the children were kept alive (and were spinning away, using all available CPU in gvisor scheduler code, which is a separate scary issue) Updates #cleanup Change-Id: I9c891ed1a1ec639fb2afec2808c04dbb8a460e0e Co-authored-by: Maisem Ali <maisem@tailscale.com> Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	1 year ago

Aaron Klotz	5fb1695bcb	util/osdiag, util/osdiag/internal/wsc: add code to probe the Windows Security Center for installed software The Windows Security Center is a component that manages the registration of security products on a Windows system. Only products that have obtained a special cert from Microsoft may register themselves using the WSC API. Practically speaking, most vendors do in fact sign up for the program as it enhances their legitimacy. From our perspective, this is useful because it gives us a high-signal source of information to query for the security products installed on the system. I've tied this query into the osdiag package and is run during bugreports. It uses COM bindings that were automatically generated by my prototype metadata processor, however that program still has a few bugs, so I had to make a few manual tweaks. I dropped those binding into an internal package because (for the moment, at least) they are effectively purpose-built for the osdiag use case. We also update the wingoes dependency to pick up BSTR.

Brad Fitzpatrick	88cc0ad9f7	util/linuxfw: remove yet-unused code to fix linux/arm64 crash The util/linuxfw/iptables.go had a bunch of code that wasn't yet used (in prep for future work) but because of its imports, ended up initializing code deep within gvisor that panicked on init on arm64 systems not using 4KB pages. This deletes the unused code to delete the imports and remove the panic. We can then cherry-pick this back to the branch and restore it later in a different way.
