* wg-quick: freebsd: allow loopback to workJason A. Donenfeld2019-01-241-1/+1
| | | | | | | | | | | | FreeBSD adds a route for point-to-point destination addresses. We don't really want to specify any destination address, but unfortunately we have to. Before we tried to cheat by giving our own address as the destination, but this had the unfortunate effect of preventing loopback from working on our local ip address. We work around this with yet another kludge: we set the destination address to 127.0.0.1. Since 127.0.0.1 is already assigned to an interface, this has the same effect of not specifying a destination address, and therefore we accomplish the intended behavior.

| | | | | | | | | The former was just a wrapper around the latter, and so upstream is now removing it. Also adjust the compat kludge to deal with this. Reported-by: Alex Xu <alex@alxu.ca>

* netlink: auth socket changes against namespace of socketJason A. Donenfeld2018-12-301-0/+7
| | | | | | | | | | | | | | | | | | In WireGuard, the underlying UDP socket lives in the namespace where the interface was created and doesn't move if the interface is moved. This allows one to create the interface in some privileged place that has Internet access, and then move it into a container namespace that only has the WireGuard interface for egress. Consider the following situation: 1. Interface created in namespace A. Socket therefore lives in namespace A. 2. Interface moved to namespace B. Socket remains in namespace A. 3. Namespace B now has access to the interface and changes the listen port and/or fwmark of socket. Change is reflected in namespace A. This behavior is arguably _fine_ and perhaps even expected or acceptable. But there's also an argument to be made that B should have A's cred to do so. So, this patch adds a simple ns_capable check.

* compat: don't undef BUILD_BUG_ON for Clang >=8Nathan Chancellor2018-12-071-1/+1
| | | | | | | | | | | | | | | | | This has been fixed upstream. To keep this hack working for toolchains that don't have it, use CONFIG_CLANG_VERSION, which was added in commit 469cb7376c06 ("kconfig: add CC_IS_CLANG and CLANG_VERSION"), introduced in 4.18. I have added the '!defined(CONFIG_CLANG_VERSION)' to keep the hack around for Android. Most custom kernel developers are using AOSP's Clang, which currently does not have the fix and might not for a while (although it is probably on Google's mind given that it has been an issue for ChromeOS on 4.19: https://crbug.com/897215). I have verified this change against my Pixel 2 kernel and 4.20-rc3 with the latest ToT Clang.

* perlasm: avoid rep retJason A. Donenfeld2018-11-151-1/+1
| | | | | | | | The original hardcodes returns as .byte 0xf3,0xc3, aka "rep ret". We replace this by "ret". "rep ret" was meant to help with AMD K8 chips, cf. http://repzret.org/p/repzret. It makes no sense to continue to use this kludge for code that won't even run on ancient AMD chips.
