* conn, device, tun: implement vectorized I/O plumbingJordan Whited2023-03-101-7/+7
| | | | | | | | | | | | | | | | | | | | Accept packet vectors for reading and writing in the tun.Device and conn.Bind interfaces, so that the internal plumbing between these interfaces now passes a vector of packets. Vectors move untouched between these interfaces, i.e. if 128 packets are received from conn.Bind.Read(), 128 packets are passed to tun.Device.Write(). There is no internal buffering. Currently, existing implementations are only adjusted to have vectors of length one. Subsequent patches will improve that. Also, as a related fixup, use the unix and windows packages rather than the syscall package when possible.

* device: combine debug and info log levels into 'verbose'Jason A. Donenfeld2021-01-261-10/+7
| | | | | | | | | | | | There are very few cases, if any, in which a user only wants one of these levels, so combine it into a single level. While we're at it, reduce indirection on the loggers by using an empty function rather than a nil function pointer. It's not like we have retpolines anyway, and we were always calling through a function with a branch prior, so this seems like a net gain. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
* device: change logging interface to use functionsJosh Bleecher Snyder2021-01-261-11/+10
| | | | | | | | | | | | | | | | | | | | | This commit overhauls wireguard-go's logging. The primary, motivating change is to use a function instead of a *log.Logger as the basic unit of logging. Using functions provides a lot more flexibility for people to bring their own logging system. It also introduces logging helper methods on Device. These reduce line noise at the call site. They also allow for log functions to be nil; when nil, instead of generating a log line and throwing it away, we don't bother generating it at all. This spares allocation and pointless work. This is a breaking change, although the fix required of clients is fairly straightforward. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>
