2021-02-20tstest/staticcheck: import the main package to fix "go mod tidy"Filippo Valsorda2-1/+4
Importing the non-main package was missing some dependencies that "go mod tidy" would then cleanup. Also added a non-ignore build tag to avoid other tools getting upset about importing a main package. Signed-off-by: Filippo Valsorda <hi@filippo.io>

2021-02-18wgengine/router: make Linux delRoute idempotent, cidrDiff fail late as possibleBrad Fitzpatrick2-5/+128
This makes cidrDiff do as much as possible before failing, and makes a delete of an already-deleted rule be a no-op. We should never do this ourselves, but other things on the system can, and this should help us recover a bit. Also adds the start of root-requiring tests. TODO: hook into wgengine/monitor and notice when routes are changed behind our back, and invalidate our routes map and re-read from kernel (via the ip command) at least on the next reconfig call.

Tangentially related to #987, #177, #594, #925, #505 Motivated by rebooting a launchd-controlled tailscaled and it going into SetNetworkUp(false) mode immediately because there really is no network up at system boot, but then it got stuck in that paused state forever, without a monitor implementation.

2021-02-12net/interfaces: reconcile interface filtering with address printing in logsBrad Fitzpatrick1-10/+18
The interface.State logging tried to only log interfaces which had interesting IPs, but the what-is-interesting checks differed between the code that gathered the interface names to print and the printing of their addresses.
2021-02-12wgengine/magicsock: retry and re-send packets in TestTwoDevicePingJosh Bleecher Snyder1-28/+42
When a handshake race occurs, a queued data packet can get lost. TestTwoDevicePing expected that the very first data packet would arrive. This caused occasional flakes. Change TestTwoDevicePing to repeatedly re-send packets and succeed when one of them makes it through. This is acceptable (vs making WireGuard not drop the packets) because this only affects communication with extremely old clients. And those extremely old clients will eventually connect, because the kernel will retry sends on timeout. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>

2021-02-12wgengine/magicsock: reduce log spam during testsJosh Bleecher Snyder1-4/+5
Only do the type assertion to *net.UDPAddr when addr is non-nil. This prevents a bunch of log spam during tests.
2021-02-12wgengine/magicsock: remove an alloc from ReceiveIPvNJosh Bleecher Snyder2-24/+132
We modified the standard net package to not allocate a *net.UDPAddr during a call to (*net.UDPConn).ReadFromUDP if the caller's use of the *net.UDPAddr does not cause it to escape. That is https://golang.org/cl/291390. This is the companion change to magicsock. There are two changes required. First, call ReadFromUDP instead of ReadFrom, if possible. ReadFrom returns a net.Addr, which is an interface, which always allocates. Second, reduce the lifetime of the returned *net.UDPAddr. We do this by immediately converting it into a netaddr.IPPort. We left the existing RebindingUDPConn.ReadFrom method in place, as it is required to satisfy the net.PacketConn interface. With the upstream change and both of these fixes in place, we have removed one large allocation per packet received. name old time/op new time/op delta ReceiveFrom-8 16.7µs ± 5% 16.4µs ± 8% ~ (p=0.310 n=5+5) name old alloc/op new alloc/op delta ReceiveFrom-8 112B ± 0% 64B ± 0% -42.86% (p=0.008 n=5+5) name old allocs/op new allocs/op delta ReceiveFrom-8 3.00 ± 0% 2.00 ± 0% -33.33% (p=0.008 n=5+5) Co-authored-by: Sonia Appasamy <sonia@tailscale.com> Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>
2021-02-12wgengine/magicsock: unify on netaddr types in addrSetJosh Bleecher Snyder3-129/+74
addrSet maintained duplicate lists of netaddr.IPPorts and net.UDPAddrs. Unify to use the netaddr type only. This makes (*Conn).ReceiveIPvN a bit uglier, but that'll be cleaned up in a subsequent commit. This is preparatory work to remove an allocation from ReceiveIPv4.
