Sonia Appasamy	1df2d14c8f	client/web: use auth ID in browser sessions ... Stores ID from tailcfg.WebClientAuthResponse in browser session data, and uses ID to hit control server /wait endpoint. No longer need the control url cached, so removed that from Server. Also added optional timeNow field, initially to manage time from tests.

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.

Tyler Smalley	35376d52d4	cmd/tailscale/cli: [serve/funnel] provide correct command for disabling (#9859) ... The `off` subcommand removes a serve/funnel for the corresponding type and port.

Jordan Whited	891d964bd4	wgengine/magicsock: simplify tryEnableUDPOffload() (#9872) ... Don't assume Linux lacks UDP_GRO support if it lacks UDP_SEGMENT support.

Joe Tsai	d603d18956	taildrop: fix TestResume (#9874) ... Previously, the test simply relied on: defer close() to cleanup file handles. This works fine on Unix-based systems, but not on Windows, which dislikes deleting files where an open file handle continues to exist. Fix the test by explicitly closing the file handle after we are done with the resource. Updates tailscale/corp#14772 Signed-off-by: Joe Tsai <joetsai@digital-static.net>	1 year ago

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	a8fbe284b2	taildrop: fix theoretical race condition (#9866) ... WaitGroup.Wait should not be concurrently called WaitGroup.Add.

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.

Joe Tsai	7971333603	ipn: fix localapi and peerapi protocol for taildrop resume (#9860) ... Minor fixes: * The branch for listing or hashing partial files was inverted. * The host for peerapi call needs to be real (rather than bogus). * Handle remote peers that don't support resuming. * Make resume failures non-fatal (since we can still continue). This was tested locally, end-to-end system test is future work.

Andrew Lytvynov	77127a2494	clientupdate: fix background install for linux tarballs (#9852) ... Two bug fixes: 1. when tailscale update is executed as root, `os.UserCacheDir` may return an error because `$XDG_CACHE_HOME` and `$HOME` are not set; fallback to `os.TempDir` in those cases 2. on some weird distros (like my EndeavourOS), `/usr/sbin` is just a symlink to `/usr/bin`; when we resolve `tailscale` binary path from `tailscaled`, allow `tailscaled` to be in either directory Updates #755 Signed-off-by: Andrew Lytvynov <awly@tailscale.com>	1 year ago
Sonia Appasamy	c27870e160	client/web: refactor authorizeRequest ... Moves request authorization back into Server.serve to be run at the start of any request.

Joe Tsai	c2a551469c	taildrop: implement asynchronous file deletion (#9844) ... File resumption requires keeping partial files around for some time, but we must still eventually delete them if never resumed. Thus, we implement asynchronous file deletion, which could spawn a background goroutine to delete the files. We also use the same mechanism for deleting files on Windows, where a file can't be deleted if there is still an open file handle. We can enqueue those with the asynchronous file deleter as well.

Maisem Ali	e6ab7d3c14	cmd/testwrapper: parse args better ... Previously we were just smushing together args and not trying to parse the values at all. This resulted in the args to testwrapper being limited and confusing. This makes it so that testwrapper parses flags in the exact format as `go test` command and passes them down in the provided order. It uses tesing.Init to register flags that `go test` understands, however those are not the only flags understood by `go test` (such as `-exec`) so we register these separately.

Maisem Ali	4899c2c1f4	cmd/containerboot: revert to using tailscale up ... This partially reverts commits a61a9ab087 and 7538f38671 and fully reverts 4823a7e591. The goal of that commit was to reapply known config whenever the container restarts. However, that already happens when TS_AUTH_ONCE was false (the default back then). So we only had to selectively reapply the config if TS_AUTH_ONCE is true, this does exactly that. This is a little sad that we have to revert to `tailscale up`, but it fixes the backwards incompatibility problem.
