Brad Fitzpatrick	af277a6762	controlclient, magicsock: add debug knob to request IPv6 endpoints Add opt-in method to request IPv6 endpoints from the control plane. For now they should just be skipped. A previous version of this CL was unconditional and reportedly had problems that I can't reproduce. So make it a knob until the mystery is solved.

David Anderson	0be475ba46	Revert "tailcfg, controlclient, magicsock: request IPv6 endpoints, but ignore them" Breaks something deep in wireguard or magicsock's brainstem, no packets at all can flow. All received packets fail decryption with "invalid mac1". This reverts commit `94024355ed`. Signed-off-by: David Anderson <dave@natulte.net>	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
