Brad Fitzpatrick db2436c7ff wgengine/magicsock: don't interrupt endpoint updates, merge all mutex into one ... Before, endpoint updates were constantly being interrupted and resumed on Linux due to tons of LinkChange messages from over-zealous Linux netlink messages (from router_linux.go) Now that endpoint updates are fast and bounded in time anyway, just let them run to completion, but note that another needs to be scheduled after. Now logs went from pages of noise to just: root@taildoc:~# grep -i -E 'stun|endpoint update' log 2020/03/13 08:51:29 magicsock.Conn: starting endpoint update (initial) 2020/03/13 08:51:30 magicsock.Conn.ReSTUN: endpoint update active, need another later ("link-change-minor") 2020/03/13 08:51:31 magicsock.Conn: starting endpoint update (link-change-minor) 2020/03/13 08:51:31 magicsock.Conn.ReSTUN: endpoint update active, need another later ("link-change-minor") 2020/03/13 08:51:33 magicsock.Conn: starting endpoint update (link-change-minor) 2020/03/13 08:51:33 magicsock.Conn.ReSTUN: endpoint update active, need another later ("link-change-minor") 2020/03/13 08:51:35 magicsock.Conn: starting endpoint update (link-change-minor) 2020/03/13 08:51:35 magicsock.Conn.ReSTUN: endpoint update active, need another later ("link-change-minor") Or, seen in another run: 2020/03/13 08:45:41 magicsock.Conn: starting endpoint update (periodic) 2020/03/13 08:46:09 magicsock.Conn: starting endpoint update (periodic) 2020/03/13 08:46:21 magicsock.Conn: starting endpoint update (link-change-major) 2020/03/13 08:46:37 magicsock.Conn: starting endpoint update (periodic) 2020/03/13 08:47:05 magicsock.Conn: starting endpoint update (periodic) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>		5 years ago
