Brad Fitzpatrick 7cf8ec8108 net/tlsdial: bake in LetsEncrypt's ISRG Root X1 root ... We still try the host's x509 roots first, but if that fails (like if the host is old), we fall back to using LetsEncrypt's root and retrying with that. tlsdial was used in the three main places: logs, control, DERP. But it was missing in dnsfallback. So added it there too, so we can run fine now on a machine with no DNS config and no root CAs configured. Also, move SSLKEYLOGFILE support out of DERP. tlsdial is the logical place for that support. Fixes #1609 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>		2021-10-01 08:30:07 -07:00
