Jack Doan	b3194236aa	udp_linux: wrap socket operations with syscall.RawConn for clean teardown (#1654) ... remove runtime.LockOSThread() because it makes things worse now remove the "custom" Write() method from tun_linux.go, the stdlib path via os.File performs better We should change our guidance around number of routines, ~2 per thread (that you wish to use for Nebula) seems to be about right now	2026-04-14 18:25:24 -05:00

Ben Ritcey	01cddb8013	Added firewall.rules.hash metric (#1010) ... * Added firewall.rules.hash metric Added a FNV-1 hash of the firewall rules as a Prometheus value. * Switch FNV has to int64, include both hashes in log messages * Use a uint32 for the FNV hash Let go-metrics cast the uint32 to a int64, so it won't be lossy when it eventually emits a float64 Prometheus metric.	2023-11-28 11:56:47 -05:00

Wade Simmons	0b67b19771	add boringcrypto Makefile targets (#856) ... This adds a few build targets to compile with `GOEXPERIMENT=boringcrypto`: - `bin-boringcrypto` - `release-boringcrypto` It also adds a field to the intial start up log indicating if boringcrypto is enabled in the binary.	2023-05-04 15:42:45 -04:00

Nate Brown	6b3d42efa5	Use atomic.Pointer for certState (#833)	2023-03-30 13:04:09 -05:00
Wade Simmons	9af242dc47	switch to new sync/atomic helpers in go1.19 (#728) ... These new helpers make the code a lot cleaner. I confirmed that the simple helpers like `atomic.Int64` don't add any extra overhead as they get inlined by the compiler. `atomic.Pointer` adds an extra method call as it no longer gets inlined, but we aren't using these on the hot path so it is probably okay.	2022-10-31 13:37:41 -04:00
Wade Simmons	7b9287709c	add listen.send_recv_error config option (#670) ... By default, Nebula replies to packets it has no tunnel for with a `recv_error` packet. This packet helps speed up re-connection in the case that Nebula on either side did not shut down cleanly. This response can be abused as a way to discover if Nebula is running on a host though. This option lets you configure if you want to send `recv_error` packets always, never, or only to private network remotes. valid values: always, never, private This setting is reloadable with SIGHUP.	2022-06-27 12:37:54 -04:00

Wade Simmons	44cb697552	Add more metrics (#450) ... * Add more metrics This change adds the following counter metrics: Metrics to track packets dropped at the firewall: firewall.dropped.local_ip firewall.dropped.remote_ip firewall.dropped.no_rule Metrics to track handshakes attempts that have been initiated and ones that have timed out (ones that have completed are tracked by the existing "handshakes" histogram). handshake_manager.initiated handshake_manager.timed_out Metrics to track when cached_packets are dropped because we run out of buffer space, and how many are sent once the handshake completes. hostinfo.cached_packets.dropped hostinfo.cached_packets.sent This change also notes how many cached packets we have when we log the final "Handshake received" message for either stage1 for stage2. * separate incoming/outgoing metrics * remove "allowed" firewall metrics We don't need this on the hotpath, they aren't worh it. * don't need pointers here	2021-04-27 22:23:18 -04:00
