2022-04-05wireguard: prevent segfault on non-adj packetsJon Loeliger1-0/+5
An unexpected packet that shows up on a Wireguard interace that happens not to have a forwarding peer will cause a segfault trying to index the vector of peers by adjacency. Rather than segfaulting, recognize a non-adjacent packet and drop it instead. This leaves open the question of what _should_ be happening to, say, IPv6 multicast packets.

2022-01-24wireguard: fix passing argumentGabriel Oginski1-1/+1
Fixed coverity-issue CID 248456. Originally passing argument of type "uint64_t *" to function: "memcopy_s_inline". This patch fixes the problem by changing type of passing argument and make a portable assumption.

2022-01-21wireguard: add async mode for encryption packetsGabriel Oginski1-25/+427
Originally wireguard doesn't support async mode for encryption packets. This patch add async mode for encryption in wireguard and also adds support chacha20-poly1305 algorithm in cryptodev for async handler. In addition it contains new command line to activate async mode for wireguard: set wireguard async mode on|off and also add new command to check active mode for wireguard: show wireguard mode Type: improvement Signed-off-by: Gabriel Oginski <gabrielx.oginski@intel.com> Change-Id: I141d48b42ee8dbff0112b8542ab5205268089da6
2022-01-20wireguard: add burst modeGabriel Oginski1-23/+77
Originally wireguard does packet by packet encryption and decryption. This patch adds burst mode for encryption and decryption packets. In addition, it contains some performance improvement such as prefetching packet header and reducing the number of current time function calls.

2021-11-03wireguard: reduce memcopy and prefetch headerGabriel Oginski1-14/+20
Originally wireguard implementation does memory copy of the whole packet in encryption and decryption. This patch removes unnecessary packet copy in wireguard. In addition, it contains some performance improvement such as prefetching header and deleting unnecessary lock and unlock for decryption.
