Marwan Sulaiman	a1d4144b18	cmd/tailscale: combine foreground and background serve logic Previously, foreground mode only worked in the simple case of `tailscale funnel <port>`. This PR ensures that whatever you can do in the background can also be done in the foreground such as setting mount paths or tcp forwarding.

David Anderson	0909e90890	util/lru: replace container/list with a custom ring implementation pre-generics container/list is quite unpleasant to use, and the pointer manipulation operations for an LRU are simple enough to implement directly now that we have generic types. With this change, the LRU uses a ring (aka circularly linked list) rather than a simple doubly-linked list as its internals, because the ring makes list manipulation edge cases more regular: the only remaining edge case is the transition between 0 and 1 elements, rather than also having to deal specially with manipulating the first and last members of the list. While the primary purpose was improved readability of the code, as it turns out removing the indirection through an interface box also speeds up the LRU: │ before.txt │ after.txt │ │ sec/op │ sec/op vs base │ LRU-32 67.05n ± 2% 59.73n ± 2% -10.90% (p=0.000 n=20) │ before.txt │ after.txt │ │ B/op │ B/op vs base │ LRU-32 21.00 ± 0% 10.00 ± 0% -52.38% (p=0.000 n=20) │ before.txt │ after.txt │ │ allocs/op │ allocs/op vs base │ LRU-32 0.000 ± 0% 0.000 ± 0% ~ (p=1.000 n=20) ¹ Updates #cleanup Signed-off-by: David Anderson <danderson@tailscale.com>	1 year ago

Marwan Sulaiman	50990f8931	ipn, ipn/ipnlocal: add Foreground field for ServeConfig This PR adds a new field to the serve config that can be used to identify which serves are in "foreground mode" and then can also be used to ensure they do not get persisted to disk so that if Tailscaled gets ungracefully shutdown, the reloaded ServeConfig will not have those ports opened.

Paul Scott	9a56184bef	cmd/tailscale: Check App Store tailscaled dialable before selecting. (#9234 ) PR #9217 attempted to fix the same issue, but suffered from not letting the user connect to non-oss tailscaled if something was listening on the socket, as the --socket flag doesn't let you select the mac apps. Rather than leave the user unable to choose, we keep the mac/socket preference order the same and check a bit harder whether the macsys version really is running. Now, we prefer the App Store Tailscale (even if it's Stopped) and you can use --socket to sswitch. But if you quit the App Store Tailscale, we'll try the socket without needing the flag.

Aaron Klotz	7d60c19d7d	clientupdate/distsign: add ability to validate a binary that is already located on disk Our build system caches files locally and only updates them when something changes. Since I need to integrate some distsign stuff into the build system to validate our Windows 7 MSIs, I want to be able to check the cached copy of a package before downloading a fresh copy from pkgs. If the signature changes, then obviously the local copy is outdated and we return an error, at which point we call Download to refresh the package.

Maisem Ali	d06a75dcd0	ipn/ipnlocal: fix deadlock in resetControlClientLocked resetControlClientLocked is called while b.mu was held and would call cc.Shutdown which would wait for the observer queue to drain.

This makes it so that resetControlClientLocked does not call Shutdown, and instead just returns the value. It also makes it so that any status received from previous cc are ignored.

Will Norris	9a3bc9049c	client/web,cmd/tailscale: add prefix flag for web command We already had a path on the web client server struct, but hadn't plumbed it through to the CLI. Add that now and use it for Synology and QNAP instead of hard-coding the path.

To repro, add this to tstest/integration: func TestFailInFewSeconds(t testing.T) { t.Parallel() time.Sleep(3 time.Second) os.Exit(1) t.Fatal("boom") } Those three seconds let the other parallel tests (with all their tailscaled child processes) start up and start running their tests, but then we violently os.Exit(1) the test driver and all the children were kept alive (and were spinning away, using all available CPU in gvisor scheduler code, which is a separate scary issue) Updates #cleanup Change-Id: I9c891ed1a1ec639fb2afec2808c04dbb8a460e0e Co-authored-by: Maisem Ali <maisem@tailscale.com> Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	1 year ago
