Not useful now but quite possibly later.
2018-09-16Change queueing drop order and fix memory leaksJason A. Donenfeld2-75/+47
If the queues are full, we drop the present packet, which is better for network traffic flow. Also, we try to fix up the memory leaks with not putting buffers from our shared pool.

2018-09-16Fixed port overwrite issue on kernels without ipv6Mathias Hall-Andersen1-13/+35
Fixed an issue in CreateBind for Linux: If ipv6 was not supported the error code would be correctly identified as EAFNOSUPPORT and ipv4 binding attempted. However the port would be set to 0, which results in the subsequent create4 call requesting a random port rather than the one provided to CreateBind. This issue was identified by: Kent Friis <leeloored@gmx.com>

2018-09-02uapi: insert peer version placeholderJason A. Donenfeld1-0/+8
While we don't want people to ever use old protocols, people will complain if the API "changes", so explicitly make the unset protocol mean the latest, and add a dummy mechanism of specifying the protocol on a per-peer basis, which we hope nobody actually ever uses.

2018-06-02Makefile: export PWD for OpenBSD's ksh(1)Jason A. Donenfeld1-1/+1
Interestingly, ksh(1) on OpenBSD does not export PWD by default, and it also has a notion of the "logical cwd" vs the "physical cwd", with the latter being passed to chdir, but the former being stored in the non-exported PWD and displayed to the user. This means that if you `cd` into a directory that's comprised of symlinks, exec'd processes will see the physical path. Observe: # ksh # mkdir a # ln -s a b # cd b # pwd /root/b # ksh -c pwd /root/a The fact of separating physical and logical paths is not too uncommon for shells (bash does it too), but not exporting PWD is very odd. Since this is common behavior for many shells, libraries that return the working directory will do something strange: they `stat(".")` and then `stat(getenv("PWD"))`, and if these point to the same inode, they roll with the value of `getenv("PWD")`, or otherwise fallback to asking the kernel for the cwd. Since PWD was not exported by ksh(1), Go's dep utility did not understand it was operating inside of our faked GOPATH and became upset. This patch works around the whole situation by simply exporting PWD before executing dep.
