David Anderson	c9a4dbe383	tool/gocross: correctly embed the git commit into gocross Previously, the build ended up embedding an empty string, which made the shell wrapper rebuild gocross on every invocation. This is still reasonably fast, but fixing the bypass shaves 80% off gocross's overhead when no rebuild is needed. Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago

David Anderson	e7a78bc28f	tool/gocross: support running from outside the repo dir A bunch of us invoke tool/go from outside the repo that hosts gocross, as a way of accessing our version-controlled toolchain. This removes assumptions from gocross that it's being invoked within the repository that contains its source code and toolchain configuration.

David Anderson	df02bb013a	tool/gocross: fail if the toolchain revision isn't findable This used to make sense, but after a refactor somewhere along the line this results in trying to download from a malformed URL and generally confusing failures.

Denton Gentry	ebc630c6c0	net/interfaces: also allow link-local for AzureAppServices. In May 2021, Azure App Services used 172.16.x.x addresses: ``` 10: eth0@if11: <BROADCAST,MULTICAST,UP,LOWER_UP,M-DOWN> mtu 1500 qdisc noqueue state UP link/ether 02:42:ac:10:01:03 brd ff:ff:ff:ff:ff:ff inet 172.16.1.3/24 brd 172.16.1.255 scope global eth0 valid_lft forever preferred_lft forever ``` Now it uses link-local: ``` 2: eth0@if6: <BROADCAST,MULTICAST,UP,LOWER_UP,M-DOWN> mtu 1500 qdisc noqueue state UP link/ether 8a:30:1f:50:1d:23 brd ff:ff:ff:ff:ff:ff inet 169.254.129.3/24 brd 169.254.129.255 scope global eth0 valid_lft forever preferred_lft forever ``` This is reasonable for them to choose to do, it just broke the handling in net/interfaces. This PR proposes to: 1. Always allow link-local in LocalAddresses() if we have no better address available. 2. Continue to make isUsableV4() conditional on an environment we know requires it. I don't love the idea of having to discover these environments one by one, but I don't understand the consequences of making isUsableV4() return true unconditionally. It makes isUsableV4() essentially always return true and perform no function. Fixes https://github.com/tailscale/tailscale/issues/7603 Signed-off-by: Denton Gentry <dgentry@tailscale.com>	2 years ago
Andrew Dunham	ccace1f7df	ssh/tailssh: fix privilege dropping on FreeBSD; add tests On FreeBSD and Darwin, changing a process's supplementary groups with setgroups(2) will also change the egid of the process, setting it to the first entry in the provided list. This is distinct from the behaviour on other platforms (and possibly a violation of the POSIX standard). Because of this, on FreeBSD with no TTY, our incubator code would previously not change the process's gid, because it would read the newly-changed egid, compare it against the expected egid, and since they matched, not change the gid. Because we didn't use the 'login' program on FreeBSD without a TTY, this would propagate to a child process. This could be observed by running "id -p" in two contexts. The expected output, and the output returned when running from a SSH shell, is: andrew@freebsd:~ $ id -p uid andrew groups andrew However, when run via "ssh andrew@freebsd id -p", the output would be: $ ssh andrew@freebsd id -p login root uid andrew rgid wheel groups andrew (this could also be observed via "id -g -r" to print just the gid) We fix this by pulling the details of privilege dropping out into their own function and prepending the expected gid to the start of the list on Darwin and FreeBSD. Finally, we add some tests that run a child process, drop privileges, and assert that the final UID/GID/additional groups are what we expect.

Anton Tolchanov	654b5a0616	derp: add optional debug logging for prober clients This allows tracking packet flow via logs for prober clients. Note that the new sclient.debug() function is called on every received packet, but will do nothing for most clients. I have adjusted sclient logging to print public keys in short format rather than full. This takes effect even for existing non-debug logging (mostly client disconnect messages). Example logs for a packet being sent from client [SbsJn] (connected to derper [dM2E3]) to client [10WOo] (connected to derper [AVxvv]): ``` derper [dM2E3]: derp client 10.0.0.1:35470[SbsJn]: register single client mesh("10.0.1.1"): 4 peers derp client 10.0.0.1:35470[SbsJn]: read frame type 4 len 40 err <nil> derp client 10.0.0.1:35470[SbsJn]: SendPacket for [10WOo], forwarding via <derphttp_client.Client [AVxvv] url=https://10.0.1.1/derp>: <nil> derp client 10.0.0.1:35470[SbsJn]: read frame type 0 len 0 err EOF derp client 10.0.0.1:35470[SbsJn]: read EOF derp client 10.0.0.1:35470[SbsJn]: sender failed: context canceled derp client 10.0.0.1:35470[SbsJn]: removing connection derper [AVxvv]: derp client 10.0.1.1:50650[10WOo]: register single client derp client 10.0.1.1:50650[10WOo]: received forwarded packet from [SbsJn] via [dM2E3] derp client 10.0.1.1:50650[10WOo]: sendPkt attempt 0 enqueued derp client 10.0.1.1:50650[10WOo]: sendPacket from [SbsJn]: <nil> derp client 10.0.1.1:50650[10WOo]: read frame type 0 len 0 err EOF derp client 10.0.1.1:50650[10WOo]: read EOF derp client 10.0.1.1:50650[10WOo]: sender failed: context canceled derp client 10.0.1.1:50650[10WOo]: removing connection ``` Signed-off-by: Anton Tolchanov <anton@tailscale.com>	2 years ago

David Anderson	df3996cae3	tool/gocross: bootstrap correctly on an older toolchain Sometimes, our cached toolchain ends up being an older version of Go, older than our go.mod allows. In that scenario, gocross-wrapper.sh would find a usable toolchain, but then fail to compile gocross. This change makes the wrapper script check that the cached toolchain's minor version is good enough to build tailscale.com, and re-bootstraps in shell if not.

Mihai Parparita	97b6d3e917	sockstats: remove per-interface stats from Get They're not needed for the sockstats logger, and they're somewhat expensive to return (since they involve the creation of a map per label). We now have a separate GetInterfaces() method that returns them instead (which we can still use in the PeerAPI debug endpoint). If changing sockstatlog to sample at 10,000 Hz (instead of the default of 10Hz), the CPU usage would go up to 59% on a iPhone XS. Removing the per-interface stats drops it to 20% (a no-op implementation of Get that returns a fixed value is 16%).

David Anderson	9ebab961c9	version/mkversion: don't break on tagged go.mod entries I thought our versioning scheme would make go.mod include a commit hash even on stable builds. I was wrong.
