James Tucker	6f69fe8ad7	wgnengine: remove unused field in userspaceEngine ... Updates #cleanup Signed-off-by: James Tucker <james@tailscale.com>	1 year ago
Tyler Smalley	269a498c1e	cmd/tailscale/cli: serve --set-path should not force background mode (#9905) ... A few people have run into issues with understanding why `--set-path` started in background mode, and/or why they couldn't use a path in foreground mode. This change allows `--set-path` to be used in either case (foreground or background). updates #8489 Signed-off-by: Tyler Smalley <tyler@tailscale.com>	1 year ago
Thomas Kosiewski	b2ae8fdf80	derp/derphttp: strip port numbers from URL hostname ... When trying to set up multiple derper instances meshing with each other, it turned out that while one can specify an alternative listening port using the -a flag, the TLS hostname gets incorrectly determined and includes the set alternative listening port as part of the hostname. Thus, the TLS hostname validation always fails when the -mesh-with values have ports. Updates #9949 Signed-off-by: Thomas Kosiewski <thomas.kosiewski@loft.sh>	1 year ago
Brad Fitzpatrick	514539b611	wgengine/magicsock: close disco listeners on Conn.Close, fix Linux root TestNewConn ... TestNewConn now passes as root on Linux. It wasn't closing the BPF listeners and their goroutines. The code is still a mess of two Close overlapping code paths, but that can be refactored later. For now, make the two close paths more similar. Updates #9945 Change-Id: I8a3cf5fb04d22ba29094243b8e645de293d9ed85 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	1 year ago
Andrew Lytvynov	593c086866	clientupdate: distinguish when auto-updates are possible (#9896) ... clientupdate.Updater will have a non-nil Update func in a few cases where it doesn't actually perform an update: * on Arch-like distros, where it prints instructions on how to update * on macOS app store version, where it opens the app store page Add a new clientupdate.Arguments field to cause NewUpdater to fail when we hit one of these cases. This results in c2n updates being "not supported" and `tailscale set --auto-update` returning an error. Updates #755 Signed-off-by: Andrew Lytvynov <awly@tailscale.com>	1 year ago
James Tucker	7df6f8736a	wgengine/netstack: only add addresses to correct protocols ... Prior to an earlier netstack bump this code used a string conversion path to cover multiple cases of behavior seemingly checking for unspecified addresses, adding unspecified addresses to v6. The behavior is now crashy in netstack, as it is enforcing address length in various areas of the API, one in particular being address removal. As netstack is now protocol specific, we must not create invalid protocol addresses - an address is v4 or v6, and the address value contained inside must match. If a control path attempts to do something otherwise it is now logged and skipped rather than incorrect addressing being added.

Andrew Lytvynov	e561f1ce61	clientupdate: manually restart Windows GUI after update (#9906) ... When updating via c2n, `tailscale.exe update` runs from `tailscaled.exe` which runs as SYSTEM. The MSI installer does not start the GUI when running as SYSTEM. This results in Tailscale just existing on auto-update, which is ungood. Instead, always ask the MSI installer to not launch the GUI (via `TS_NOLAUNCH` argument) and launch it manually with a token from the current logged in user. The token code was borrowed from d9081d6ba2/net/dns/wsl_windows.go (L207-L232) Also, make some logging changes so that these issues are easier to debug in the future.

Adrian Dewhurst	5347e6a292	control/controlclient: support certstore without cgo ... We no longer build Windows releases with cgo enabled, which automatically turned off certstore support.

Sonia Appasamy	68da15516f	ipn/localapi,client/web: clean up auth error handling ... This commit makes two changes to the web client auth flow error handling: 1. Properly passes back the error code from the noise request from the localapi. Previously we were using io.Copy, which was always setting a 200 response status code. 2. Clean up web client browser sessions on any /wait endpoint error. This avoids the user getting in a stuck state if something goes wrong with their auth path.

Andrew Lytvynov	70f9c8a6ed	clientupdate: change Mac App Store support (#9891) ... In the sandboxed app from the app store, we cannot check `/Library/Preferences/com.apple.commerce.plist` or run `softwareupdate`. We can at most print a helpful message and open the app store page. Also, reenable macsys update function to mark it as supporting c2n updates. macsys support in `tailscale update` was fixed. Updates #755 Signed-off-by: Andrew Lytvynov <awly@tailscale.com>	1 year ago

Joe Tsai	6ada33db77	taildrop: fix theoretical race condition in fileDeleter.Init (#9876) ... It is possible that upon a cold-start, we enqueue a partial file for deletion that is resumed shortly after startup. If the file transfer happens to last longer than deleteDelay, we will delete the partial file, which is unfortunate. The client spent a long time uploading a file, only for it to be accidentally deleted. It's a very rare race, but also a frustrating one if it happens to manifest. Fix the code to only delete partial files that do not have an active puts against it. We also fix a minor bug in ResumeReader where we read b[:blockSize] instead of b[:cs.Size]. The former is the fixed size of 64KiB, while the latter is usually 64KiB, but may be less for the last block.

Joe Tsai	469b7cabad	cmd/tailscale: improve taildrop progress printer on Linux (#9878) ... The progress printer was buggy where it would not print correctly and some of the truncation logic was faulty. The progress printer now prints something like: go1.21.3.linux-amd64.tar.gz 21.53MiB 13.83MiB/s 33.88% ETA 00:00:03 where it shows * the number of bytes transferred so far * the rate of bytes transferred (using a 1-second half-life for an exponentially weighted average) * the progress made as a percentage * the estimated time (as calculated from the rate of bytes transferred) Other changes: * It now correctly prints the progress for very small files * It prints at a faster rate (4Hz instead of 1Hz) * It uses IEC units for byte quantities (to avoid ambiguities of "kb" being kilobits or kilobytes) Updates tailscale/corp#14772 Signed-off-by: Joe Tsai <joetsai@digital-static.net>	1 year ago
Tyler Smalley	7a3ae39025	cmd/tailscale/cli: [serve/funnel] support omitting scheme for TCP (#9856) ... The `serve` command for TCP has always required the scheme of the target to be specified. However, when it's omitted the error message reported is misleading ``` error: failed to apply TCP serve: invalid TCP target "localhost:5900": missing port in address ``` Since we know the target is TCP, we shouldn't require it to be specified.

Joe Tsai	d603d18956	taildrop: fix TestResume (#9874) ... Previously, the test simply relied on: defer close() to cleanup file handles.

Maisem Ali	c3a8e63100	util/linuxfw: add additional nftable detection logic ... We were previously using the netlink API to see if there are chains/rules that already exist. This works fine in environments where there is either full nftable support or no support at all. However, we have identified certain environments which have partial nftable support and the only feasible way of detecting such an environment is to try to create some of the chains that we need. This adds a check to create a dummy postrouting chain which is immediately deleted. The goal of the check is to ensure we are able to use nftables and that it won't error out later. This check is only done in the path where we detected that the system has no preexisting nftable rules.

Joe Tsai	3f27087e9d	taildrop: switch hashing to be streaming based (#9861) ... While the previous logic was correct, it did not perform well. Resuming is a dance between the client and server, where 1. the client requests hashes for a partial file, 2. the server then computes those hashes, 3. the client computes hashes locally and compares them. 4. goto 1 while the partial file still has data While step 2 is running, the client is sitting idle. While step 3 is running, the server is sitting idle. By streaming over the block hash immediately after the server computes it, the client can start checking the hash, while the server works on the next hash (in a pipelined manner). This performs dramatically better and also uses less memory as we don't need to hold a list of hashes, but only need to handle one hash at a time. There are two detriments to this approach: * The HTTP API relies on a JSON stream, which is not a standard REST-like pattern. However, since we implement both client and server, this is fine. * While the stream is on-going, we hold an open file handle on the server side while the file is being hashed. On really slow streams, this could hold a file open forever.
