ipn/ipnlocal,wgengine/netstack: move LocalBackend specifc serving logic to LocalBackend

2023-06-12T19:56:07Z

The netstack code had a bunch of logic to figure out if the LocalBackend should handle an incoming connection and then would call the function directly on LocalBackend. Move that logic to LocalBackend and refactor the methods to return conn handlers. Updates #cleanup Signed-off-by: Maisem Ali

wgengine/netstack: use ping6 on BSD platforms

2023-05-28T16:50:21Z

Various BSD-derived operating systems including macOS and FreeBSD require that ping6 be used for IPv6 destinations. The "ping" command does not understand an IPv6 destination. FreeBSD 13.x and later do handle IPv6 in the regular ping command, but also retain a ping6 command. We use ping6 on all versions of FreeBSD.

envknob,net/tstun,wgengine: use TS_DEBUG_MTU consistently

2023-03-30T21:26:10Z

Noted on #5915 TS_DEBUG_MTU was not used consistently everywhere. Extract the default into a function that can apply this centrally and use it everywhere. Added envknob.Lookup{Int,Uint}Sized to make it easier to keep CodeQL happy when using converted values. Updates #5915 Signed-off-by: James Tucker

wgengine/netstack: do not send packets to netstack after close

2023-03-29T02:55:45Z

Use the local context on Impl to check for shut down state in order to drop rather than inject packets after close has begun. Netstack sets endpoint.dispatcher to nil during shutdown. After the recent adjustment in 920ec69241930c352818b0bf3eab20e62df93ed1 we now wait for netstack to fully shutdown before we release tests. This means that we may continue to accept packets and attempt to inject them, which we must prevent in order to avoid nil pointer panic.

all: pass log IDs as the proper type rather than strings

2023-03-23T18:26:55Z

This change focuses on the backend log ID, which is the mostly commonly used in the client. Tests which don't seem to make use of the log ID just use the zero value. Signed-off-by: Will Norris
