Encode entropy value in UDP source port when requested per RFC 7510. CLI already has "src-port-is-entropy", use zero UDP source port in API to avoid breaking changes, since zero port is not something to be used in wild.

2022-09-27wireguard: stop sending handshakes when wg intf is downAlexander Chernavin1-3/+66
Type: fix Currently, when a wg interface is administratively disabled initially or during operation, handshake packets continue to be sent. Data packets stop being sent because routes pointing to the wg interface will not be used. But data keys remain. With this fix, when a wg interface is administratively disabled during peer creation, avoid connection initialization to the peer. Data keys and timers should be empty at this point. When a wg interface is disabled during operation, disable all peers (i.e. stop all timers, clear data keys, etc.). Thus, state should be identical in both cases. When a wg interface is administratively enabled, enable all peers (i.e. get ready to exchange data packets and initiate a connection). Also, cover these scenarios with tests.

2022-09-27crypto-openssl: use no padding for encrypt/decryptVladimir Ratnikov1-6/+1
Internaly, vpp uses it's own padding, so all the data is padded using blocksize in /src/vnet/ipsec/ipsec.c Openssl should add it's own padding, but the data is already padded. So on decrypt stage when padding should be removed, it can't be done. And it produces error `bad decrypt` Previous versions of openSSL decrypted data almost at the beginning of EVP_DecryptUpdate/EVP_DecryptFinal_ex and produced the same error, but data was already decrypted.

2022-09-27wireguard: fix re-handshake timer when response sentAlexander Chernavin1-1/+0
Type: fix As per the protocol: A handshake initiation is retried after "REKEY_TIMEOUT + jitter" ms, if a response has not been received... Currently, if retransmit handshake timer is started, it will trigger after "REKEY_TIMEOUT + jitter" ms and will try to send a handshake initiation via wg_send_handshake() given that no responses have been received. wg_send_handshake() will verify that time stored in REKEY_TIMEOUT has passed since last handshake initiation sending and if has, will send a handshake initiation. Time when a handshake initiation was last sent is stored in last_sent_handshake. The problem is that last_sent_handshake is not only updated in wg_send_handshake() when sending handshake initiations but also in wg_send_handshake_response() when sending handshake responses. When retransmit handshake timer triggers and a handshake response has been sent recently, a handshake initiation will not be sent because for wg_send_handshake() it will look like that time stored in REKEY_TIMEOUT has not passed yet. Also, the timer will not be restarted. wg_send_handshake_response() must not update last_sent_handshake, because this time is used only when sending handshake intitiations. And the protocol does not say that handshake initiation retransmission and handshake response sending (i.e. replying to authenticated handshake initiations) must coordinate. With this fix, stop updating last_sent_handshake in wg_send_handshake_response(). Also, this fixes tests that used to wait for "REKEY_TIMEOUT + 1" seconds and did not receive any handshake initiations. Then they fail. Also, long-running tests that send wrong packets and do not expect anything in reply may now receive handshake intiations, consider them as replies to the wrond packets, and fail. Those are updated to filter out handshake initiations in such verifications. Moreover, after sending wrong packets, error counters are already inspected there to confirm packet processing was unsuccessful.

2022-09-15nat: fix nat44-ed port range with multiple workersVladislav Grishenko4-8/+15
The number of available dynamic ports is set to (0xffff - 1024) = 64511, which is not divisable by the pow2 number of workers - the only integer divisors are 31 and 2081. So, total dynamic port range of all workers will be less than it: 1 wrk: n = (port_per_thread = 64511/1)*1 = 64511 + 1025 = 65536 2 wrk: n = (port_per_thread = 64511/2)*2 = 64510 + 1025 = 65535 4 wrk: n = (port_per_thread = 64511/4)*4 = 64508 + 1025 = 65533 8 wrk: n = (port_per_thread = 64511/8)*8 = 64504 + 1025 = 65529 ... As seen, with multiple workers there are unused trailing ports for every nat pool address and that is the reason of out-of-bound index in the worker array on out2in path due (port - 1024) / port_per_thread math. This was fixed in 5c9f9968de63fa627b4a72b344df36cdc686d18a, so packets to unused ports will go to existing worker and dropped there. Per RFC 6335 https://www.rfc-editor.org/rfc/rfc6335#section-6: 6. Port Number Ranges o the System Ports, also known as the Well Known Ports, from 0-1023 (assigned by IANA) o the User Ports, also known as the Registered Ports, from 1024- 49151 (assigned by IANA) o the Dynamic Ports, also known as the Private or Ephemeral Ports, from 49152-65535 (never assigned) According that let's allocate dynamic ports from 1024 and have full port range with a wide range of the workers number - 64 integer divisors in total, including pow2 ones: 1 wrk: n = (port_per_thread = 64512/1)*1 = 64512 + 1024 = 65536 2 wrk: n = (port_per_thread = 64512/2)*2 = 64512 + 1024 = 65536 3 wrk: n = (port_per_thread = 64512/3)*3 = 64512 + 1024 = 65536 4 wrk: n = (port_per_thread = 64512/4)*4 = 64512 + 1024 = 65536 5 wrk: n = (port_per_thread = 64512/5)*5 = 64510 + 1024 = 65534 6 wrk: n = (port_per_thread = 64512/6)*6 = 64512 + 1024 = 65536 7 wrk: n = (port_per_thread = 64512/7)*7 = 64512 + 1024 = 65536 8 wrk: n = (port_per_thread = 64512/8)*8 = 64512 + 1024 = 65536 ... Modulo from 5c9f9968de63fa627b4a72b344df36cdc686d18a is still required when the numbers of workers is not the integer divisor of 64512.

2022-08-30memif: Process bad descriptors correctly in memif_process_descSteven Luong1-10/+35
When there is a bad descriptor, it may in the beginning, in the middle, or at the end of the batch if the batch has more than 3 descriptors. When processing a bad descriptor is encountered in the batch, we need to rollback n_buffers in memif_process_desc(), or the statement in the same function memif_add_copy_op (ptd, mb0 + src_off, bytes_to_copy, dst_off, n_buffers - 1); is wrong because it picks up the wrong buffer_vec_index of the bad descriptor while parsing a good descriptor immediately following the bad descriptor. n_buffers was incremented in the beginning of while (n_left) loop. The other problem is we should count the number of bad packets and reduce ptd->n_packets to get the correct number of packets for subsequent processing in device_input. The last fix is to check if n_buffers == 0 in device_input and skip doing any descriptor copy. This case can happen when all the descriptors are bad in the batch.

2022-08-25vlib: introduce DMA infrastructureMarvin Liu6-0/+890
This patch introduces DMA infrastructure into vlib. This is well known that large amount of memory movements will drain core resource. Nowadays more and more hardware accelerators were designed out for freeing core from this burden. Meanwhile some restrictions still remained when utilizing hardware accelerators, e.g. cross numa throughput will have a significant drop compared to same node. Normally the number of hardware accelerator instances will less than cores number, not to mention that applications number will even beyond the number of cores. Some hardware may support share virtual address with cores, while others are not. Here we introduce new DMA infrastructure which can fulfill the requirements of vpp applications like session and memif and in the meantime dealing with hardware limitations. Here is some design backgrounds: Backend is the abstract of resource which allocated from DMA device and can do some basic operations like configuration, DMA copy and result query. Config is the abstract of application DMA requirement. Application need to request an unique config index from DMA infrastructure. This unique config index is associated with backend resource. Two options cpu fallback and barrier before last can be specified in config. DMA transfer will be performed by CPU when backend is busy if cpu fallback option is enabled. DMA transfer callback will be in order if barrier before last option is enabled. We constructs all the stuffs that DMA transfer request needed into DMA batch. It contains the pattern of DMA descriptors and function pointers for submission and callback. One DMA transfer request need multiple times batch update and one time batch submission. DMA backends will assigned to config's workers threads equally. Lock will be used for thread-safety if same backends assigned to multiple threads. Backend node will check all the pending requests in worker thread and do callback with the pointer of DMA batch if transfer completed. Application can utilize cookie in DMA batch for selves usage.

2022-08-18nat: Replace port refcounts with simple bitvectorsJon Loeliger2-17/+80
Previously, each address maintained an array of 32-bit reference counts for each of 65K possible ports for each of 4 NAT protocols. Totalling 1MB per address. Wow. A close read of the code shows that an "is used" check precedes each attempted reference count increment. That means the refcount never actually gets above 1. That in turn means algorithmically, a bit vector is sufficient. And one need not be allocated for more than the highest validated port referenced. These changes introduce a dynamically sized bit vector replacing the reference counts, for a maximum of 32K if all 4 protocols use port 65535. In fact, protocol OTHER is never used, so at most 24K will be used, and none of it will be "statically" allocated per address.

2022-08-18ikev2: accept key exchange on CREATE_CHILD_SAAtzm Watanabe2-63/+126
In RFC 7296, CREATE_CHILD_SA Exchange may contain the KE payload to enable stronger guarantees of forward secrecy. When the KEi payload is included in the CREATE_CHILD_SA request, responder should reply with the KEr payload and complete the key exchange, in accordance with the RFC.

2022-08-17memif: crash on recceiving a bad descriptorSteven Luong1-1/+1
We validate each descriptor via memif_validate_desc_data and set desc_status to non-zero for the corresponding descriptor when the descriptor is bad. However, desc_status is not propagated back to xor_status in memif_validate_desc_data which eventually sets ptd->xor_status. Not setting ptd->xor_status causes us to treat all descriptors as "simple". In that case, when we try to copy also the bad descriptors to the buffers, it results a crash since desc_data is not set to point to the correct memory in the descriptor. The fix is to set xor_status in memif_validate_desc_data such that if there is a bad descriptor in the frame, "is_simple" is set to false and we have to selectively copy only the good descriptors to the buffers.

2022-08-17wireguard: fix fib entry trackingAlexander Chernavin2-53/+35
Type: fix After peers roaming support addition, FIB entry tracking stopped working. For example, it can be observed when an adjacency is stacked on a FIB entry by the plugin and the FIB entry hasn't got ARP resolution yet. Once the FIB entry gets ARP resolution, the adjacency is not re-stacked as it used to. This results in endless ARP requests when a traffic is sent via the adjacency. This is broken because the plugin stopped using "midchain delegate" with peers roaming support addition. The reason is that "midchain delegate" didn't support stacking on a different FIB entry which is needed when peer's endpoint changes. Now it is supported there (added in 36892). With this fix, start using "midchane delegate" again and thus, fix FIB entry tracking. Also, cover this in tests.

2022-08-16nat: fix potential out-of-bound worker array indexJing Peng3-24/+36
In several NAT submodules, the number of available ports (0xffff - 1024) may not be divisible by the number of workers, so port_per_thread is determined by integer division, which is the floor of the quotient. Later when a worker index is needed, dividing the port with port_per_thread may yield an out-of-bound array index into the workers array. As an example, assume 2 workers are configured, then port_per_thread will be (0xffff - 1024) / 2, which is 32255. When we compute a worker index with port 0xffff, we get (0xffff - 1024) / 32255, which is 2, but since we only have 2 workers, only 0 and 1 are valid indices. This patch fixes the problem by adding a modulo at the end of the division. Type: fix Signed-off-by: Jing Peng <pj.hades@gmail.com> Change-Id: Ieae3d5faf716410422610484a68222f1c957f3f8
