2017-10-02netlink: switch from ioctl to netlink for configurationJason A. Donenfeld

2017-09-18queue: entirely rework parallel systemJason A. Donenfeld
This removes our dependency on padata and moves to a different mode of multiprocessing that is more efficient. This began as Samuel Holland's GSoC project and was gradually reworked/redesigned/rebased into this present commit, which is a combination of his initial contribution and my subsequent rewriting and redesigning.

2017-06-26global: cleanup IP header checkingJason A. Donenfeld
This way is more correct and ensures we're within the skb head. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

This logic belongs upstream. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2017-06-26ratelimiter: rewrite from scratchJason A. Donenfeld
This not only removes the depenency on x_tables, but it also gives us much better performance and memory usage. Now, systems are able to have millions of WireGuard interfaces, without having to worry about a thundering herd of garbage collection. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2017-06-24device: only use one sleep notifierJason A. Donenfeld
This greatly improves performance when adding and removing interfaces, since the power registration function does a linear search each time. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2017-02-21device: disable ICMP redirectsJason A. Donenfeld
The xfrm layer does this by checking for secpath, but we don't use secpath, so instead we have to jigger the config value ourselves. This is nearly always desired, since this is often how a wheel-spoke VPN works. There's very little use case for redirects with wireguard. This should be reverted if we ever move the test directly into ip_forward in net/ipv4/ip_forward.c near the call to ip_rt_send_redirect. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2016-12-11device: allocate tstats in newlinkJason A. Donenfeld
Every place else does this in ndo_init, but this seems completely redundant, so to simplify things, I'm moving it into newlink. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2016-12-09device: make suspend code conditional on CONFIG_PM_SLEEPJason A. Donenfeld
This isn't actually neccessary, since there are no-op stubs for these functions, but the MIPS people don't want any unneccessary bloat. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
