Brad Fitzpatrick	8a187159b2	cmd/ssh-auth-none-demo: add demo SSH server that acts like Tailscale SSH For SSH client authors to fix their clients without setting up Tailscale stuff. Change-Id: I8c7049398512de6cb91c13716d4dcebed4d47b9c Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Brad Fitzpatrick	b2994568fe	ipn/localapi: put all the LocalAPI methods into a map Rather than a bunch of switch cases. Change-Id: Id1db813ec255bfab59cbc982bee351eb36373245 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Maisem Ali	f172fc42f7	ssh/tailssh: close sshContext on context cancellation This was preventing tailscaled from shutting down properly if there were active sessions in certain states (e.g. waiting in check mode). Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago
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

Brad Fitzpatrick	6d76764f37	ipn/ipnlocal: fix taildrop target list UI bug The macOS and iOS apps that used the /localapi/v0/file-targets handler were getting too many candidate targets. They wouldn't actually accept the file. This is effectively just a UI glitch in the wrong hosts being listed as valid targets from the source side. Change-Id: I6907a5a1c3c66920e5ec71601c044e722e7cb888 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Maisem Ali	b84ec521bf	ssh/tailssh: do not send EOT on session disconnection This was assumed to be the fix for mosh not working, however turns out all we really needed was the duplicate fd also introduced in the same commit (`af412e8874`). Fixes #5103 Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago
Joe Tsai	82f5f438e0	wgengine/wgcfg: plumb down audit log IDs (#5855 ) The node and domain audit log IDs are provided in the map response, but are ultimately going to be used in wgengine since that's the layer that manages the tstun.Wrapper. Do the plumbing work to get this field passed down the stack. Signed-off-by: Joe Tsai <joetsai@digital-static.net>	2 years ago
Mihai Parparita	92ad56ddcb	cmd/tsconnect: close the SSH session an unload event instead of beforeunload The window may not end up getting unloaded (if other beforeunload handlers prevent the event), thus we should only close the SSH session if it's truly getting unloaded. Updates tailscale/corp#7304 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Joe Tsai	84e8f25c21	net/tstun: rename statististics method (#5852 ) Rename StatisticsEnable as SetStatisticsEnabled to be consistent with other similarly named methods. Rename StatisticsExtract as ExtractStatistics to follow the convention where methods start with a verb. It was originally named with Statistics as a prefix so that statistics related methods would sort well in godoc, but that property no longer holds. Signed-off-by: Joe Tsai <joetsai@digital-static.net>	2 years ago
Joe Tsai	dd045a3767	net/flowtrack: add json tags to Tuple (#5849 ) By convention, JSON serialization uses camelCase. Specify such names on the Tuple type. Signed-off-by: Joe Tsai <joetsai@digital-static.net>	2 years ago
Joe Tsai	a73c423c8a	net/tunstats: add Counts.Add (#5848 ) The Counts.Add method merges two Counts together. Signed-off-by: Joe Tsai <joetsai@digital-static.net>	2 years ago
Joe Tsai	3af0d4d0f2	logtail: always record timestamps in UTC (#5732 ) Upstream optimizations to the Go time package will make unmarshaling of time.Time 3-6x faster. See: * https://go.dev/cl/425116 * https://go.dev/cl/425197 * https://go.dev/cl/429862 The last optimization avoids a []byte -> string allocation if the timestamp string less than than 32B. Unfortunately, the presence of a timezone breaks that optimization. Drop recording of timezone as this is non-essential information. Most of the performance gains is upon unmarshal, but there is also a slight performance benefit to not marshaling the timezone as well.

Joe Tsai	c321363d2c	logtail: support a copy ID (#5851 ) The copy ID operates similar to a CC in email where a message is sent to both the primary ID and also the copy ID. A given log message is uploaded once, but the log server records it twice for each ID. Signed-off-by: Joe Tsai <joetsai@digital-static.net>	2 years ago
Joe Tsai	24ebf161e8	net/tstun: instrument Wrapper with statistics gathering (#5847 ) If Wrapper.StatisticsEnable is enabled, then per-connection counters are maintained. If enabled, Wrapper.StatisticsExtract must be periodically called otherwise there is unbounded memory growth. Signed-off-by: Joe Tsai <joetsai@digital-static.net>	2 years ago

Tom DNetto	8602061f32	ipn/ipnlocal,tka: Fix bugs found by integration testing * tka.State.staticValidateCheckpoint could call methods on a contained key prior to calling StaticValidate on that key * Remove broken backoff / RPC retry logic from tka methods in ipn/ipnlocal, to be fixed at a later time * Fix NetworkLockModify() which would attempt to take b.mu twice and deadlock, remove now-unused dependence on netmap * Add methods on ipnlocal.LocalBackend to be used in integration tests * Use TAILSCALE_USE_WIP_CODE as the feature flag so it can be manipulated in tests Signed-off-by: Tom DNetto <tom@tailscale.com>	2 years ago

Mihai Parparita	7ffd2fe005	cmd/tsconnect: switch to non-beta versions of xterm and related packages xterm 5.0 was released a few weeks ago, and it picks up xtermjs/xterm.js#4069, which was the main reason why we were on a 5.0 beta. Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Joe Tsai	2934c5114c	net/tunstats: new package to track per-connection counters (#5818 ) High-level API: type Statistics struct { ... } type Counts struct { TxPackets, TxBytes, RxPackets, RxBytes uint64 } func (Statistics) UpdateTx([]byte) func (Statistics) UpdateRx([]byte) func (*Statistics) Extract() map[flowtrack.Tuple]Counts The API accepts a []byte instead of a packet.Parsed so that a future implementation can directly hash the address and port bytes, which are contiguous in most IP packets. This will be useful for a custom concurrent-safe hashmap implementation. Signed-off-by: Joe Tsai <joetsai@digital-static.net>	2 years ago
David Anderson	bdf3d2a63f	cmd/pgproxy: open-source our postgres TLS-enforcing proxy. From the original commit that implemented it: It accepts Postgres connections over Tailscale only, dials out to the configured upstream database with TLS (using strong settings, not the swiss cheese that postgres defaults to), and proxies the client through. It also keeps an audit log of the sessions it passed through, along with the Tailscale-provided machine and user identity of the connecting client. In our other repo, this was: commit 92e5edf98e8c2be362f564a408939a5fc3f8c539, Change-Id I742959faaa9c7c302bc312c7dc0d3327e677dc28.

Brad Fitzpatrick	bb7be74756	net/dns/publicdns: permit more NextDNS profile bits in its IPv6 suffix I brain-o'ed the math earlier. The NextDNS prefix is /32 (actually /33, but will guarantee last bit is 0), so we have 128-32 = 96 bits (12 bytes) of config/profile ID that we can extract. NextDNS doesn't currently use all those, but might. Updates #2452 Change-Id: I249bd28500c781e45425fd00fd3f46893ae226a2 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
