Brad Fitzpatrick	abd79ea368	derp: reduce DERP memory use; don't require callers to pass in memory to use The magicsock derpReader was holding onto 65KB for each DERP connection forever, just in case. Make the derp{,http}.Client be in charge of memory instead. It can reuse its bufio.Reader buffer space.	4 years ago

Brad Fitzpatrick	1cb7dab881	cmd/derper: support forwarding packets amongst set of peer DERP servers Updates #388 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	5e0ff494a5	derp: change NewClient constructor to an option pattern (The NewMeshClient constructor I added recently was gross in retrospect at call sites, especially when it wasn't obvious that a meshKey empty string meant a regular client)	4 years ago
Brad Fitzpatrick	484b7fc9a3	derp, cmd/derper: add frameWatchConns, framePeerPresent for inter-DERP routing This lets a trusted DERP client that knows a pre-shared key subscribe to the connection list. Upon subscribing, they get the current set of connected public keys, and then all changes over time. This lets a set of DERP server peers within a region all stay connected to each other and know which clients are connected to which nodes.

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>	4 years ago

Brad Fitzpatrick	322cb58b14	derp: deflake test I flaked up in earlier change I broke an invariant in `11048b8932` (it was even nicely documented then). Also clean up the test a bit from while I was debugging it. Fixes #84 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
