Maisem Ali	85241f8408	net/tstun: use /10 as subnet for TAP mode; read IP from netmap Few changes to resolve TODOs in the code: - Instead of using a hardcoded IP, get it from the netmap. - Use 100.100.100.100 as the gateway IP - Use the /10 CGNAT range instead of a random /24 Updates #2589 Signed-off-by: Maisem Ali <maisem@tailscale.com>	1 month ago
Maisem Ali	d4d21a0bbf	net/tstun: restore tap mode functionality It had bit-rotted likely during the transition to vector io in `76389d8baf`. Tested on Ubuntu 24.04 by creating a netns and doing the DHCP dance to get an IP. Updates #2589 Signed-off-by: Maisem Ali <maisem@tailscale.com>	1 month ago

Will Norris	71029cea2d	all: update copyright and license headers This updates all source files to use a new standard header for copyright and license declaration. Notably, copyright no longer includes a date, and we now use the standard SPDX-License-Identifier header. This commit was done almost entirely mechanically with perl, and then some minimal manual fixes. Updates #6865 Signed-off-by: Will Norris <will@tailscale.com>	2 years ago
andig	14e8afe444	go.mod, etc: bump gvisor Fixes #6554 Change-Id: Ia04ae37a47b67fa57091c9bfe1d45a1842589aa8 Signed-off-by: andig <cpuidle@gmx.de>	2 years ago
Jordan Whited	ea5ee6f87c	all: update golang.zx2c4.com/wireguard to github.com/tailscale/wireguard-go (#6692 ) This is temporary while we work to upstream performance work in https://github.com/WireGuard/wireguard-go/pull/64. A replace directive is less ideal as it breaks dependent code without duplication of the directive. Signed-off-by: Jordan Whited <jordan@tailscale.com>	2 years ago
Jordan Whited	76389d8baf	net/tstun, wgengine/magicsock: enable vectorized I/O on Linux (#6663 ) This commit updates the wireguard-go dependency and implements the necessary changes to the tun.Device and conn.Bind implementations to support passing vectors of packets in tailscaled. This significantly improves throughput performance on Linux.

Brad Fitzpatrick	a12aad6b47	all: convert more code to use net/netip directly perl -i -npe 's,netaddr.IPPrefixFrom,netip.PrefixFrom,' $(git grep -l -F netaddr.) perl -i -npe 's,netaddr.IPPortFrom,netip.AddrPortFrom,' $(git grep -l -F netaddr. ) perl -i -npe 's,netaddr.IPPrefix,netip.Prefix,g' $(git grep -l -F netaddr. ) perl -i -npe 's,netaddr.IPPort,netip.AddrPort,g' $(git grep -l -F netaddr. ) perl -i -npe 's,netaddr.IP\b,netip.Addr,g' $(git grep -l -F netaddr. ) perl -i -npe 's,netaddr.IPv6Raw\b,netip.AddrFrom16,g' $(git grep -l -F netaddr. ) goimports -w . Then delete some stuff from the net/netaddr shim package which is no longer neeed.

Maisem Ali	9514ed33d2	go.mod: bump gvisor.dev/gvisor Pick up https://github.com/google/gvisor/pull/7787 Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago
Brad Fitzpatrick	1af26222b6	go.mod: bump netstack, switch to upstream netstack Now that Go 1.17 has module graph pruning (https://go.dev/doc/go1.17#go-command), we should be able to use upstream netstack without breaking our private repo's build that then depends on the tailscale.com Go module. This is that experiment. Updates #1518 (the original bug to break out netstack to own module) Updates #2642 (this updates netstack, but doesn't remove workaround) Change-Id: I27a252c74a517053462e5250db09f379de8ac8ff Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

Brad Fitzpatrick	a729070252	net/tstun: add start of Linux TAP support, with DHCP+ARP server Still very much a prototype (hard-coded IPs, etc) but should be non-invasive enough to submit at this point and iterate from here.
