Charlotte Brandhorst-Satzkorn	4eed2883db	words: space, the final frontier (#5952 ) Captains log. Stardate 100386.37. Work is proceeding on the Words list as Tailscalars are forced to scavenge for more taily and scaley things. Signed-off-by: Charlotte Brandhorst-Satzkorn <charlotte@tailscale.com>	2 years ago

Brad Fitzpatrick	a04f1ff9e6	logtail: default to 2s log flush delay on all platforms Per chat. This is close enough to realtime but massively reduces number of HTTP requests. (which you can verify with TS_DEBUG_LOGTAIL_WAKES and watching tailscaled run at start) By contrast, this is set to 2 minutes on mobile.

Mihai Parparita	63ad49890f	cmd/tsconnect: pre-compress main.wasm when building the NPM package This way we can do that once (out of band, in the GitHub action), instead of increasing the time of each deploy that uses the package. .wasm is removed from the list of automatically pre-compressed extensions, an OSS bump and small change on the corp side is needed to make use of this change.

Tom DNetto	a515fc517b	ipn/ipnlocal: make tkaSyncIfNeeded exclusive with a mutex Running corp/ipn#TestNetworkLockE2E has a 1/300 chance of failing, and deskchecking suggests thats whats happening are two netmaps are racing each other to be processed through tkaSyncIfNeededLocked. This happens in the first place because we release b.mu during network RPCs. To fix this, we make the tka sync logic an exclusive section, so two netmaps will need to wait for tka sync to complete serially (which is what we would want anyway, as the second run through probably wont need to sync).

James Tucker	539c073cf0	wgengine/magicsock: set UDP socket buffer sizes to 7MB - At high data rates more buffer space is required in order to avoid packet loss during any cause of delay. - On slower machines more buffer space is required in order to avoid packet loss while decryption & tun writing is underway. - On higher latency network paths more buffer space is required in order to overcome BDP. - On Linux set with SO_*BUFFORCE to bypass net.core.{r,w}mem_max. - 7MB is the current default maximum on macOS 12.6 - Windows test is omitted, as Windows does not support getsockopt for these options.

Brad Fitzpatrick	a315336287	logtail: change batched upload mechanism to not use CPU when idle The mobile implementation had a 2 minute ticker going all the time to do a channel send. Instead, schedule it as needed based on activity. Then we can be actually idle for long periods of time.

Mihai Parparita	b2855cfd86	derp/derphttp: fix nil pointer dereference when closing a netcheck client NewNetcheckClient only initializes a subset of fields of derphttp.Client, and the Close() call added by #5707 was result in a nil pointer dereference. Make Close() safe to call when using NewNetcheckClient() too. Fixes #5919 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
James Tucker	4ec6d41682	wgengine/router: fix MTU configuration on Windows Always set the MTU to the Tailscale default MTU. In practice we are missing applying an MTU for IPv6 on Windows prior to this patch. This is the simplest patch to fix the problem, the code in here needs some more refactoring.

Joe Tsai	a1a43ed266	wgengine/netlog: add support for magicsock statistics (#5913 ) This sets up Logger to handle statistics at the magicsock layer, where we can correlate traffic between a particular tailscale IP address and any number of physical endpoints used to contact the node that hosts that tailscale address. We also export Message and TupleCounts to better document the JSON format that is being sent to the logging infrastructure. This commit does NOT yet enable the actual logging of magicsock statistics. That will be a future commit. Signed-off-by: Joe Tsai <joetsai@digital-static.net>	2 years ago

Denton Gentry	1b9ed9f365	VERSION.txt: this is 1.33. We did not get this VERSION.txt file checked in at the correct time, the prior 10 commits in `main` between the v1.32.0 tag point and this commit were not part of release 1.32. We did no unstable builds during this time, so the error should have no impact. Signed-off-by: Denton Gentry <dgentry@tailscale.com>	2 years ago

Brad Fitzpatrick	e24de8a617	ssh/tailssh: add password-forcing workaround for buggy SSH clients If the username includes a suffix of +password, then we accept password auth and just let them in like it were no auth.

Anton Tolchanov	c070d39287	cmd/tailscaled: handle tailscaled symlink on macOS When Tailscale is installed via Homebrew, `/usr/local/bin/tailscaled` is a symlink to the actual binary. Now when `tailscaled install-system-daemon` runs, it will not attempt to overwrite that symlink if it already points to the tailscaled binary. However, if executed binary and the link target differ, the path will he overwritten - this can happen when a user decides to replace Homebrew-installed tailscaled with a one compiled from source code.

Hasnain Lakhani	8fe04b035c	tsweb: sort varz by name after stripping prefix (#5778 ) This makes it easier to view prometheus metrics. Added a test case which demonstrates the new behavior - the test initially failed as the output was ordered in the same order as the fields were declared in the struct (i.e. foo_a, bar_a, foo_b, bar_b). For that reason, I also had to change an existing test case to sort the fields in the new expected order. Signed-off-by: Hasnain Lakhani <m.hasnain.lakhani@gmail.com>	2 years ago
