Brad Fitzpatrick	d348b94505	stun, stunner: clarify an error log message more But two earlier changes mean this doesn't show up anymore anyway. But if it does, it'll be a nice message.	5 years ago

Brad Fitzpatrick	120273d7f6	portlist: document, clean up, fix an open fd spike, optimize a bit I noticed portlist when looking at some profiles and hadn't looked at the code much before. This is a first pass over it. It allocates a fair bit. More love remains, but this does a bit: name old time/op new time/op delta GetList-8 9.92ms ± 8% 9.64ms ±12% ~ (p=0.247 n=10+10) name old alloc/op new alloc/op delta GetList-8 931kB ± 0% 869kB ± 0% -6.70% (p=0.000 n=10+10) name old allocs/op new allocs/op delta GetList-8 4.59k ± 0% 3.69k ± 1% -19.71% (p=0.000 n=10+10) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago

Brad Fitzpatrick	42e98d4edc	Quiet two little log annoyances.	5 years ago
Brad Fitzpatrick	db2436c7ff	wgengine/magicsock: don't interrupt endpoint updates, merge all mutex into one Before, endpoint updates were constantly being interrupted and resumed on Linux due to tons of LinkChange messages from over-zealous Linux netlink messages (from router_linux.go) Now that endpoint updates are fast and bounded in time anyway, just let them run to completion, but note that another needs to be scheduled after. Now logs went from pages of noise to just: root@taildoc:~# grep -i -E 'stun\|endpoint update' log 2020/03/13 08:51:29 magicsock.Conn: starting endpoint update (initial) 2020/03/13 08:51:30 magicsock.Conn.ReSTUN: endpoint update active, need another later ("link-change-minor") 2020/03/13 08:51:31 magicsock.Conn: starting endpoint update (link-change-minor) 2020/03/13 08:51:31 magicsock.Conn.ReSTUN: endpoint update active, need another later ("link-change-minor") 2020/03/13 08:51:33 magicsock.Conn: starting endpoint update (link-change-minor) 2020/03/13 08:51:33 magicsock.Conn.ReSTUN: endpoint update active, need another later ("link-change-minor") 2020/03/13 08:51:35 magicsock.Conn: starting endpoint update (link-change-minor) 2020/03/13 08:51:35 magicsock.Conn.ReSTUN: endpoint update active, need another later ("link-change-minor") Or, seen in another run: 2020/03/13 08:45:41 magicsock.Conn: starting endpoint update (periodic) 2020/03/13 08:46:09 magicsock.Conn: starting endpoint update (periodic) 2020/03/13 08:46:21 magicsock.Conn: starting endpoint update (link-change-major) 2020/03/13 08:46:37 magicsock.Conn: starting endpoint update (periodic) 2020/03/13 08:47:05 magicsock.Conn: starting endpoint update (periodic) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
Brad Fitzpatrick	db31550854	wgengine: don't Reconfig on boring link changes Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
Avery Pennarun	7dd63abaed	tailcfg.NetInfo: add a .String() renderer. For pretty printing purposes in logs.	5 years ago
Avery Pennarun	b23cb11eaf	ipn: Prefs.String(): print the current derp setting.	5 years ago
David Anderson	aeb88864e0	ipn: don't clobber netinfo in Start().	5 years ago
Avery Pennarun	8b8e3f08a0	Fix staticcheck complaint.	5 years ago
Avery Pennarun	b4897e7de8	controlclient/netmap: write our own b.ConciseDiffFrom(a) function. This removes the need for go-cmp, which is extremely bloaty so we had to leave it out of iOS. As a result, we had also left it out of macOS, and so we didn't print netmap diffs at all on darwin-based platforms. Oops. As a bonus, the output format of the new function is way better. Minor oddity: because I used the dumbest possible diff algorithm, the sort order is a bit dumb. We print all "removed" lines and then print all "added" lines, rather than doing the usual diff-like thing of interspersing them. This probably doesn't matter (maybe it's an improvement).	5 years ago
Avery Pennarun	96bb05ce2f	controlclient: reformat netmap.Concise() and add DERP server info. The .Concise() view had grown hard to read over time. Originally, we assumed a peer almost always had just one endpoint and one-or-more allowedips. With magicsock, we now almost always have multiple endpoints per peer. And empirically, almost every peer has only one allowedip. Change their order so we can line up allowedips vertically. Also do some tweaking to make multiple endpoints easier to read. While we're here, add a column to show the home DERP server of each peer, if any.	5 years ago
Avery Pennarun	f2e2ffa423	controlclient: log the entire netmap up to every 5 minutes. We log it once upon receiving the first copy of the map, then subsequently when a new one appears, but only if we haven't logged one less than 5 minutes ago. This avoids overly cluttering the log (as we did before, logging the netmap every time one appeared, which could be hundreds of lines every few seconds), but still gives the log enough context to help in diagnosing problems retroactively.	5 years ago

David Crawshaw	72dbf26f63	derp: test that client a->b and a->c relaying do not interfere Without the recent write deadline introduction, this test fails. They still do interfere, but the interference is now bound by the write deadline. Many improvements are possible. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	5 years ago

David Crawshaw	3df1b97ea8	derp: do not treat failure to relay as the fault of the sender If Alice attempts to send a packet to Bob and the DERP server encounters an error on the socket to Bob, we should not disconnect Alice for that.

David Crawshaw	43aa8595dd	derp: introduce Conn interface This lets us test with something other than a net.Conn. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	5 years ago
David Crawshaw	41ac4a79d6	net/nettest: new package with net-like testing primitives This is a lot like wiring up a local UDP socket, read and write deadlines work. The big difference is the Block feature, which lets you stop the packet flow without breaking the connection. This lets you emulate broken sockets and test timeouts actually work.

David Crawshaw	7ec54e0064	wgengine/magicsock: remove TODO The TODO above derphttp.NewClient suggests it does network I/O, but the derphttp client connects lazily and so creating one is very cheap. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	5 years ago
