Brad Fitzpatrick	da8def8e13	all: remove old +build tags ... The //go:build syntax was introduced in Go 1.17: https://go.dev/doc/go1.17#build-lines gofmt has kept the +build and go:build lines in sync since then, but enough time has passed. Time to remove them. Done with: perl -i -npe 's,^// \+build.*\n,,' $(git grep -l -F '+build') Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
James Tucker	539c073cf0	wgengine/magicsock: set UDP socket buffer sizes to 7MB ... - At high data rates more buffer space is required in order to avoid packet loss during any cause of delay. - On slower machines more buffer space is required in order to avoid packet loss while decryption & tun writing is underway. - On higher latency network paths more buffer space is required in order to overcome BDP. - On Linux set with SO_*BUFFORCE to bypass net.core.{r,w}mem_max. - 7MB is the current default maximum on macOS 12.6 - Windows test is omitted, as Windows does not support getsockopt for these options.

Andrew Dunham	c72caa6672	wgengine/magicsock: use AF_PACKET socket + BPF to read disco messages ... This is entirely optional (i.e. failing in this code is non-fatal) and only enabled on Linux for now. Additionally, this new behaviour can be disabled by setting the TS_DEBUG_DISABLE_AF_PACKET environment variable.
