2022-03-09tun/netstack: update to latest wireguard-goAlexander Neumann
This commit fixes all callsites of netip.AddrFromSlice(), which has changed its signature and now returns two values. Signed-off-by: Alexander Neumann <alexander.neumann@redteam-pentesting.de> [Jason: remove error handling from AddrFromSlice.] Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2022-02-02tun/netstack: simplify read timeout on ping socketJason A. Donenfeld
I'm not 100% sure this is correct, but it certainly is a lot simpler. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2022-02-02tun/netstack: implement ICMP pingThomas H. Ptacek
Provide a PacketConn interface for netstack's ICMP endpoint; netstack currently only provides EchoRequest/EchoResponse ICMP support, so this code exposes only an interface for doing ping.

2021-11-29device: handle peer post config on blank lineJason A. Donenfeld
We missed a function exit point. This was exacerbated by e3134bf ("device: defer state machine transitions until configuration is complete"), but the bug existed prior. Minus provided the following useful reproducer script: #!/usr/bin/env bash set -eux make wireguard-go || exit 125 ip netns del test-ns || true ip netns add test-ns ip link add test-kernel type wireguard wg set test-kernel listen-port 0 private-key <(echo "QMCfZcp1KU27kEkpcMCgASEjDnDZDYsfMLHPed7+538=") peer "eDPZJMdfnb8ZcA/VSUnLZvLB2k8HVH12ufCGa7Z7rHI=" allowed-ips 10.51.234.10/32 ip link set test-kernel netns test-ns up ip -n test-ns addr add 10.51.234.1/24 dev test-kernel port=$(ip netns exec test-ns wg show test-kernel listen-port) ip link del test-go || true ./wireguard-go test-go wg set test-go private-key <(echo "WBM7qimR3vFk1QtWNfH+F4ggy/hmO+5hfIHKxxI4nF4=") peer "+nj9Dkqpl4phsHo2dQliGm5aEiWJJgBtYKbh7XjeNjg=" allowed-ips 0.0.0.0/0 endpoint 127.0.0.1:$port ip addr add 10.51.234.10/24 dev test-go ip link set test-go up ping -c2 -W1 10.51.234.1 Reported-by: minus <minus@mnus.de> Signed-off-by: Jason A.

2021-11-23device: reduce peer lock critical section in UAPIJosh Bleecher Snyder
The deferred RUnlock calls weren't executing until all peers had been processed. Add an anonymous function so that each peer may be unlocked as soon as it is completed. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2021-11-23global: use netip where possible nowJason A. Donenfeld
There are more places where we'll need to add it later, when Go 1.18 comes out with support for it in the "net" package. Also, allowedips still uses slices internally, which might be suboptimal. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2021-11-16device: only propagate roaming value before peer is referenced elsewhereJason A. Donenfeld
A peer.endpoint never becomes nil after being not-nil, so creation is the only time we actually need to set this. This prevents a race from when the variable is actually used elsewhere, and allows us to avoid an expensive atomic. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2021-07-29memmod: fix protected delayed load the right wayJason A. Donenfeld
The reason this was failing before is that dloadsup.h's DloadObtainSection was doing a linear search of sections to find which header corresponds with the IMAGE_DELAYLOAD_DESCRIPTOR section, and we were stupidly overwriting the VirtualSize field, so the linear search wound up matching the .text section, which then it found to not be marked writable and failed with FAST_FAIL_DLOAD_PROTECTION_FAILURE.

2021-07-29memmod: disable protected delayed load for nowJason A. Donenfeld
