Brad Fitzpatrick	51976ab3a2	tsweb: add vars for unix process start time and version To be scraped in the Go expvar JSON format, as a string is involved. For a future tool to record when processes restarted exactly, and at what version. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

Brad Fitzpatrick	f35b8c3ead	derp: fix meshing accounting edge case bug If a peer is connected to multiple nodes in a region (so multiForwarder is in use) and then a node restarts and re-sends all its additions, this bug about whether an element is in the multiForwarder could cause a one-time flip in the which peer node we forward to. Note a huge deal, but not written as intended. Thanks to @lewgun for the bug report in #2141. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

Denton Gentry	6731f934a6	Revert "wgengine: actively log FlushDNS." This log is quite verbose, it was only to be left in for one unstable build to help debug a user issue. This reverts commit `1dd2552032`. Signed-off-by: Denton Gentry <dgentry@tailscale.com>	3 years ago
Brad Fitzpatrick	47045265b9	hostinfo: add SetDeviceModel setter, move remaining code from controlclient Updates tailscale/corp#1959 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Josh Bleecher Snyder	4ff0757d44	cmd/testcontrol: add test control server This is useful for manual performance testing of networks with many nodes. I imagine it'll grow more knobs over time. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Denton Gentry	1dd2552032	wgengine: actively log FlushDNS. Intended to help in resolving customer issue with DNS caching. We currently exec `ipconfig /flushdns` from two places: - SetDNS(), which logs before invoking - here in router_windows, which doesn't We'd like to see a positive indication in logs that flushdns is being run. As this log is expected to be spammy, it is proposed to leave this in just long enough to do an unstable 1.13.x build and then revert it. They won't run an unsigned image that I build.

Josh Bleecher Snyder	6ef734e493	wgengine: predict min.Peers length across calls The number of peers we have will be pretty stable across time. Allocate roughly the right slice size. This reduces memory usage when there are many peers. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	adf696172d	wgengine/userspace: reduce allocations in getStatus Two optimizations. Use values instead of pointers. We were using pointers to make track the "peer in progress" easier. It's not too hard to do it manually, though. Make two passes through the data, so that we can size our return value accurately from the beginning. This is cheap enough compared to the allocation, which grows linearly in the number of peers, that it is worth doing. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago

Josh Bleecher Snyder	4c8b5fdec4	control/controlclient: do not periodically print full netmap The netmaps can get really large. Printing, processing, and uploading them is expensive. Only print the header on an ongoing basis. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	a666b546fb	ipn/ipnlocal: log number of packet filters rather than entire filter The number of packet filters can grow very large, so this log entry can be very large. We can get the packet filter server-side, so reduce verbosity here to just the number of filters present. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	0c038b477f	logtail: add a re-usable buffer for uploads This avoids a per-upload alloc (which in practice often means per-log-line), up to 4k. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	278e7de9c9	logtail: always send a json array The code goes to some effort to send a single JSON object when there's only a single line and a JSON array when there are multiple lines. It makes the code more complex and more expensive; when we add a second line, we have to use a second buffer to duplicate the first one after adding a leading square brackets. The savings come to two bytes. Instead, always send an array. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	93284209bc	logtail/filch: preallocate a scanner buffer Scanning log lines is a frequent source of allocations. Pre-allocate a re-usable buffer. This still doesn't help when there are giant log lines. Those will still be problematic from an iOS memory perspective. For more on that, see https://github.com/tailscale/corp/issues/2423. (For those who cannot follow that link, it is a discussion of particular problematic types of log lines for particular categories of customers. The "categories of customers" part is the reason that it is a private issue.) There is also a latent bug here. If we ever encounter a log line longer than bufio.MaxScanTokenSize, then bufio.Scan will return an error, and we'll truncate the file and discard the rest of the log. That's not good, but bufio.MaxScanTokenSize is really big, so it probably doesn't matter much in practice now. Unfortunately, it does prevent us from easily capping the potential memory usage here, on pain of losing log entries. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago

Josh Bleecher Snyder	6da6d47a83	all: simplify build tags involving iOS Prior to Go 1.16, iOS used GOOS=darwin, so we had to distinguish macOS from iOS during GOARCH. We now require Go 1.16 in our go.mod, so we can simplify. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago

Brad Fitzpatrick	e804ab29fd	net/tstun: move TUN failure diagnostics to OS-specific files Mostly so the Linux one can use Linux-specific stuff in package syscall and not use os/exec for uname for portability.
