James Tucker	f7cb535693	net/speedtest: retune to meet iperf on localhost in a VM - removed some in-flow time calls - increase buffer size to 2MB to overcome syscall cost - move relative time computation from record to report time Signed-off-by: James Tucker <james@tailscale.com>	2 years ago
James Tucker	146f51ce76	net/packet: fix filtering of short IPv4 fragments The fragment offset is an 8 byte offset rather than a byte offset, so the short packet limit is now in fragment block size in order to compare with the offset value. The packet flags are in the first 3 bits of the flags/frags byte, and so after conversion to a uint16 little endian value they are at the start, not the end of the value - the mask for extracting "more fragments" is adjusted to match this byte. Extremely short fragments less than 80 bytes are dropped, but fragments over 80 bytes are now accepted. Fixes #5727 Signed-off-by: James Tucker <james@tailscale.com>	2 years ago
Mihai Parparita	c66e15772f	tsweb: consider 304s as successful for quiet logging Static resource handlers will generate lots of 304s, which are effectively successful responses. Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Andrew Dunham	e1bdbfe710	tailcfg, control/controlhttp, control/controlclient: add ControlDialPlan field (#5648 ) * tailcfg, control/controlhttp, control/controlclient: add ControlDialPlan field This field allows the control server to provide explicit information about how to connect to it; useful if the client's link status can change after the initial connection, or if the DNS settings pushed by the control server break future connections.

Aaron Klotz	acc7baac6d	tailcfg, util/deephash: add DataPlaneAuditLogID to Node and DomainDataPlaneAuditLogID to MapResponse We're adding two log IDs to facilitate data-plane audit logging: a node-specific log ID, and a domain-specific log ID. Updated util/deephash/deephash_test.go with revised expectations for tailcfg.Node. Updates https://github.com/tailscale/corp/issues/6991 Signed-off-by: Aaron Klotz <aaron@tailscale.com>	2 years ago
Kyle Carberry	91794f6498	wgengine/magicsock: move firstDerp check after nil derpMap check This fixes a race condition which caused `c.muCond.Broadcast()` to never fire in the `firstDerp` if block. It resulted in `Close()` hanging forever. Signed-off-by: Kyle Carberry <kyle@carberry.com>	2 years ago
Brad Fitzpatrick	2c447de6cc	cmd/tailscaled: use explicit equal sign in --port=$PORT in tailscaled.service Personal preference (so it's obvious it's not a bool flag), but it also matches the --state= before it. Bonus: stop allowing PORT to sneak in extra flags to be passed as their own arguments, as $FOO and ${FOO} expand differently. (${FOO} is required to concat to strings) Change-Id: I994626a5663fe0948116b46a971e5eb2c4023216 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago

Andrew Dunham	0607832397	wgengine/netstack: always respond to 4via6 echo requests (#5712 ) As the comment in the code says, netstack should always respond to ICMP echo requests to a 4via6 address, even if the netstack instance isn't normally processing subnet traffic.

Maisem Ali	d5781f61a9	ipn/ipnlocal: return usernames when Tailscale SSH is enabled It was checking if the sshServer was initialized as a proxy, but that could either not have been initialized yet or Tailscale SSH could have been disabled after intialized.

Andrew Dunham	c6162c2a94	net/netcheck: add check for captive portal (#5593 ) This doesn't change any behaviour for now, other than maybe running a full netcheck more often. The intent is to start gathering data on captive portals, and additionally, seeing this in the 'tailscale netcheck' command should provide a bit of additional information to users.

Berk D. Demir	ff13c66f55	cmd/tailscale: fix configure-host command for Synology `d5e7e309` changed the `hostinfo.GetVersion` from distro and distro version to UTS Name Release and moved distribution information under `hostinfo.Distro*`. `tailscale configure-host` command implementation for Synology DSM environments relies on the old semantics of this string for matching DSM Major version so it's been broken for a few days.

Brad Fitzpatrick	65c24b6334	envknob: generalize Windows tailscaled-env.txt support ipnserver previously had support for a Windows-only environment variable mechanism that further only worked when Windows was running as a service, not from a console. But we want it to work from tailscaed too, and we want it to work on macOS and Synology. So move it to envknob, now that envknob can change values at runtime post-init. A future change will wire this up for more platforms, and do something more for CLI flags like --port, which the bug was originally about.

Brad Fitzpatrick	4a82b317b7	ipn/{ipnlocal,localapi}: use strs.CutPrefix, add more domain validation The GitHub CodeQL scanner flagged the localapi's cert domain usage as a problem because user input in the URL made it to disk stat checks. The domain is validated against the ipnstate.Status later, and only authenticated root/configured users can hit this, but add some paranoia anyway.

Brad Fitzpatrick	45a3de14a6	cmd/tailscaled, tailcfg, hostinfo: add flag to disable logging + support As noted in #5617, our documented method of blocking log.tailscale.io DNS no longer works due to bootstrap DNS. Instead, provide an explicit flag (--no-logs-no-support) and/or env variable (TS_NO_LOGS_NO_SUPPORT=true) to explicitly disable logcatcher uploads. It also sets a bit on Hostinfo to say that the node is in that mode so we can end any support tickets from such nodes more quickly. This does not yet provide an easy mechanism for users on some platforms (such as Windows, macOS, Synology) to set flags/env. On Linux you'd used /etc/default/tailscaled typically. Making it easier to set flags for other platforms is tracked in #5114. Fixes #5617 Fixes tailscale/corp#1475 Change-Id: I72404e1789f9e56ec47f9b7021b44c025f7a373a Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
