2024-03-12misc: remove GNU Indent directivesDamjan Marion1-2/+0

2023-06-08crypto: use fixed crypto frame poolgaoginskx1-0/+2
The async frames pool may be resized once drained. This will cause 2 problems: original pool pointer is invalidated and pool size changed, both problems will confuse the crypto infra user graph nodes (like IPsec and Wireguard) and crypto engines if they expect the pool pointers always valid and the pool size never changed (for performance reason). This patch introduces fixed size of the async frames pool. This helps zeroing surprise to the components shown above and avoiding segmentation fault when pool resizing happened. In addition, the crypto engine may take advantage of the feature to sync its own pool/vector with crypto infra.

2023-06-02wireguard: add support for chained buffersAlexander Chernavin1-51/+184
Type: feature With this change, packets that are larger than a single buffer can fit will be able to be sent and received over a Wireguard tunnel. Also, cover this with tests. Signed-off-by: Alexander Chernavin <achernavin@netgate.com> Change-Id: Ifaf7325676d728580097bc389b51a9be39e44d88
2023-02-27wireguard: fix potential leaks of async frameGabriel Oginski1-12/+12
The current implementation can cause memory leaks of async frames and exhaust the async frames pool. Wireguard can early get async frame, even when later it turns out it is not needed. Then such frame won't be freed. This fix changes the moment of acquiring async frame from the pool, so it doesn't leak.

2023-02-16wireguard: move buffer when insufficient pre_data leftAlexander Skorichenko1-14/+24
Currently wg-output-tun() doesn't check if a buffer has enough space for prepending an ethernet header (wg header over ipv6 vxlan header case leaves only 8 bytes free). In such a case move buffer's content. Type: fix Change-Id: Iad18860e6b86a3d81f3d96d782de7c59556152d0 Signed-off-by: Alexander Skorichenko <askorichenko@netgate.com>

2022-08-25wireguard: fix ipv6 payload_length computationAloys Augustin1-4/+3
The ipv6 header length should not be counted in the ipv6 payload length. This is similar to https://gerrit.fd.io/r/c/vpp/+/36945. Type: fix Change-Id: I22de0ff828175829102a85288513ee3f55709108 Signed-off-by: Aloys Augustin <aloaugus@cisco.com>

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
