David Crawshaw	1147c7fd4f	net/dns: set WSL /etc/resolv.conf We also have to make a one-off change to /etc/wsl.conf to stop every invocation of wsl.exe clobbering the /etc/resolv.conf. This appears to be a safe change to make permanently, as even though the resolv.conf is constantly clobbered, it is always the same stable internal IP that is set as a nameserver. (I believe the resolv.conf clobbering predates the MS stub resolver.) Tested on WSL2, should work for WSL1 too. Fixes #775 Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	3 years ago
David Crawshaw	9b063b86c3	net/dns: factor directManager out over an FS interface This is preliminary work for using the directManager as part of a wslManager on windows, where in addition to configuring windows we'll use wsl.exe to edit the linux file system and modify the system resolv.conf. The pinholeFS is a little funky, but it's designed to work through simple unix tools via wsl.exe without invoking bash. I would not have thought it would stand on its own like this, but it turns out it's useful for writing a test for the directManager. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	3 years ago
julianknodt	72a0b5f042	net/dns/resolver: fmt item This has been bothering me for a while, but everytime I run format from the root directory it also formats this file. I didn't want to add it to my other PRs but it's annoying to have to revert it every time. Signed-off-by: julianknodt <julianknodt@gmail.com>	3 years ago

Adrian Dewhurst	bcaae3e074	net/dns/resolver: clamp EDNS size This change (subject to some limitations) looks for the EDNS OPT record in queries and responses, clamping the size field to fit within our DNS receive buffer. If the size field is smaller than the DNS receive buffer then it is left unchanged. I think we will eventually need to transition to fully processing the DNS queries to handle all situations, but this should cover the most common case. Mostly fixes #2066 Signed-off-by: Adrian Dewhurst <adrian@tailscale.com>	3 years ago
David Anderson	084d48d22d	net/dns: always proxy through quad-100 on windows 8.1. Windows 8.1 incorrectly handles search paths on an interface with no associated resolver, so we have to provide a full primary DNS config rather than use Windows 8.1's nascent-but-present NRPT functionality. Fixes #2237. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago

David Anderson	320cc8fa21	net/dns: verify that systemd-resolved is actually in charge. It's possible to install a configuration that passes our current checks for systemd-resolved, without actually pointing to systemd-resolved. In that case, we end up programming DNS in resolved, but that config never applies to any name resolution requests on the system. This is quite a far-out edge case, but there's a simple additional check we can do: if the header comment names systemd-resolved, there should be a single nameserver in resolv.conf pointing to 127.0.0.53. If not, the configuration should be treated as an unmanaged resolv.conf. Fixes #2136. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago

Adrian Dewhurst	8b11937eaf	net/dns/resolver: permit larger max responses, signal truncation This raises the maximum DNS response message size from 512 to 4095. This should be large enough for almost all situations that do not need TCP. We still do not recognize EDNS, so we will still forward requests that claim support for a larger response size than 4095 (that will be solved later). For now, when a response comes back that is too large to fit in our receive buffer, we now set the truncation flag in the DNS header, which is an improvement from before but will prompt attempts to use TCP which isn't supported yet. On Windows, WSARecvFrom into a buffer that's too small returns an error in addition to the data. On other OSes, the extra data is silently discarded. In this case, we prefer the latter so need to catch the error on Windows. Partially addresses #1123 Signed-off-by: Adrian Dewhurst <adrian@tailscale.com>	3 years ago

David Anderson	e2dcf63420	net/dns: replace AuthoritativeSuffixes with nil Route entries. This leads to a cleaner separation of intent vs. implementation (Routes is now the only place specifying who handles DNS requests), and allows for cleaner expression of a configuration that creates MagicDNS records without serving them to the OS.

Josh Bleecher Snyder	25df067dd0	all: adapt to opaque netaddr types This commit is a mishmash of automated edits using gofmt: gofmt -r 'netaddr.IPPort{IP: a, Port: b} -> netaddr.IPPortFrom(a, b)' -w . gofmt -r 'netaddr.IPPrefix{IP: a, Port: b} -> netaddr.IPPrefixFrom(a, b)' -w . gofmt -r 'a.IP.Is4 -> a.IP().Is4' -w . gofmt -r 'a.IP.As16 -> a.IP().As16' -w . gofmt -r 'a.IP.Is6 -> a.IP().Is6' -w . gofmt -r 'a.IP.As4 -> a.IP().As4' -w . gofmt -r 'a.IP.String -> a.IP().String' -w .

David Anderson	cfde997699	net/dns: don't use interfaces.Tailscale to find the tailscale interface index. interfaces.Tailscale only returns an interface if it has at least one Tailscale IP assigned to it. In the resolved DNS manager, when we're called upon to tear down DNS config, the interface no longer has IPs. Instead, look up the interface index on construction and reuse it throughout the daemon lifecycle. Fixes #1892. Signed-off-by: David Anderson <dave@natulte.net>	4 years ago
David Anderson	3c8e230ee1	Revert "net/dns: set IPv4 auto mode in NM, so it lets us set DNS." This reverts commit `7d16c8228b`. I have no idea how I ended up here. The bug I was fixing with this change fails to reproduce on Ubuntu 18.04 now, and this change definitely does break 20.04, 20.10, and Debian Buster. So, until we can reliably reproduce the problem this was meant to fix, reverting. Part of #1875 Signed-off-by: David Anderson <dave@natulte.net>	4 years ago

David Anderson	25ce9885a2	net/dns: don't use NM+resolved for NM >=1.26.6. NetworkManager fixed the bug that forced us to use NetworkManager if it's programming systemd-resolved, and in the same release also made NetworkManager ignore DNS settings provided for unmanaged interfaces... Which breaks what we used to do. So, with versions 1.26.6 and above, we MUST NOT use NetworkManager to indirectly program systemd-resolved, but thankfully we can talk to resolved directly and get the right outcome.
