* timers: clear send_keepalive timer on sending handshake responseJason A. Donenfeld2018-05-191-0/+3
| | | | | | We reorganize this into also doing so on sending keepalives itself, which means the state machine is much more consistent, even if this was already implied.

* send: account for route-based MTUJason A. Donenfeld2018-04-151-3/+4
| | | | | | | | | | It might be that a particular route has a different MTU than the interface, via `ip route add ... dev wg0 mtu 1281`, for example. In this case, it's important that we don't accidently pad beyond the end of the MTU. We accomplish that in this patch by carrying forward the MTU from the dst if it exists. We also add a unit test for this issue. Reported-by: Roman Mamedov <rm.wg@romanrm.net>

* global: add SPDX tags to all filesGreg Kroah-Hartman2017-12-091-1/+4
| | | | | | | | | | | | | It's good to have SPDX identifiers in all files as the Linux kernel developers are working to add these identifiers to all files. Update all files with the correct SPDX license identifier based on the license text of the project or based on the license in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Modified-by: Jason A.

* global: infuriating kernel iterator styleJason A. Donenfeld2017-10-311-5/+5
| | | | | | | | | | | | | | | | | One types: for (i = 0 ... So one should also type: for_each_obj (obj ... But the upstream kernel style guidelines are insane, and so we must instead do: for_each_obj(obj ... Ugly, but one must choose his battles wisely.

* send: don't take uninitialized lockJason A. Donenfeld2017-09-191-3/+3
| | | | | | Packets is a local, which means we need to use the functions that don't take a spinlock, since otherwise we'll be using a spinlock in an undefined state.

* queue: entirely rework parallel systemJason A. Donenfeld2017-09-181-60/+174
| | | | | | | | | | 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.

* send: orphan skbs when buffering longtermJason A. Donenfeld2017-07-201-1/+7
| | | | | | | | | Otherwise we quickly use up all of a socket's memory, which prevents a socket from sending packets to other interfaces. This also has the nice effect of letting TCP connections continue to attempt to begin, with the older ones being naturally rotated out and freed, so when a connection finally is made, only the later TCP connections are attempted, not the ones that would already have timed out.

| | | | | All locks are potentially between user context and softirq, which means we need to take the _bh variant.
