2020-09-14l2: allocate l2fib only when neededDamjan Marion4-10/+90
Currently l2 fib allocates 512MB hash table unconditionally on startup. This patch postpones table creation up to the point where first interface is put into l2 mode or mac entry is added. In addition it reduces default table size to 128MB and increases number of buckets 4 times. This default setting should be enough to keep 1M mac entries. Also, new startup.conf section is added which allows user to change memory and bucket size. .i.e: l2fib { table-size 512M num-buckets 524288 } Type: improvement Change-Id: I2a29209aa3545181f0087544c97a54d8157b6ec5 Signed-off-by: Damjan Marion <damarion@cisco.com>

2020-09-14session: add unix socket api for app attachmentFlorin Coras6-18/+743
This is an af_unix socket alternative to the binary api. To enable it, add use-app-socket-api under session stanza in startup.conf. When the socket api is enabled, attachments through the binary api are disabled. The socket api only works with memfd fifo segments, i.e., shm segments are not supported.

2020-09-09l2: check secondary macs on BVI interfaceMatthew Smith1-2/+35
Type: fix VRRP cannot be used on a BVI interface currently because packets sent to the virtual mac address of the VR fail the destination mac check in l2_to_bvi(). Apparently people want to use VRRP on BVI interfaces, so update the check in l2_to_bvi() so that it will check any secondary mac addresses which have been added to the ethernet interface if the destination mac address does not match the primary mac address for the interface. An equivalent check is already done in ethernet_input_inline() for L3 interfaces which are in promiscuous mode.

2020-09-07ipsec: fix padding/alignment for native IPsec encryptionChristian Hopps5-19/+19
Not all ESP crypto algorithms require padding/alignment to be the same as AES block/IV size. CCM, CTR and GCM all have no padding/alignment requirements, and the RFCs indicate that no padding (beyond ESPs 4 octet alignment requirement) should be used unless TFC (traffic flow confidentiality) has been requested. CTR: https://tools.ietf.org/html/rfc3686#section-3.2 GCM: https://tools.ietf.org/html/rfc4106#section-3.2 CCM: https://tools.ietf.org/html/rfc4309#section-3.2 - VPP is incorrectly using the IV/AES block size to pad CTR and GCM. These modes do not require padding (beyond ESPs 4 octet requirement), as a result packets will have unnecessary padding, which will waste bandwidth at least and possibly fail certain network configurations that have finely tuned MTU configurations at worst. Fix this as well as changing the field names from ".*block_size" to ".*block_align" to better represent their actual (and only) use. Rename "block_sz" in esp_encrypt to "esp_align" and set it correctly as well. test: ipsec: Add unit-test to test for RFC correct padding/alignment test: patch scapy to not incorrectly pad ccm, ctr, gcm modes as well - Scapy is also incorrectly using the AES block size of 16 to pad CCM, CTR, and GCM cipher modes.

2020-09-04ipsec: fix trace of GRE_teb packetsChristian Hopps1-2/+5
The issue is not easily hit. When GRE_teb packets are received the post crypto processing adjusts the l2.l2_len value in the vnet_buffer opaque data. This is overwriting the ipsec opaque data. Later the trace code fetches the sa_index from the ipsec opaque data. It's just an accident that this currently works, if the ipsec data is changed so that the sa_index moves around it will be overwritten by the l2_len modification. Indeed, this was found b/c local development changes had moved the sa_index so it was over-lapping with the l2_len memory space, and the UT failed.

2020-09-04ip: enhance vtep4_check of tunnel by vector wayZhiyong Yang4-36/+137
This patch aims to improve decap performance by reducing expensive hash_get callings as less as possible using AVX512 on XEON. e.g. vxlan, vxlan_gpe, geneve, gtpu. For the existing code, if vtep4 of the current packet match the last vtep4_key_t well, expensive hash computation can be avoided and the code returns directly. This patch improves tunnel decap multiple flows case greatly by leveraging 512bit vector register on XEON accommodating 8 vtep4_keys. It enhances the possiblity of avoiding unnecessary hash computing once hash key of the current packet hits any one of 8 in the 512bit cache. The oldest element in vtep4_cache_t is updated in round-robin order. vlib_get_buffers is also leveraged in the meanwhile.

2020-09-03crypto: SW scheduler async crypto enginePiotrX Kleski4-69/+232
Type: feature This patch adds new sw_scheduler async crypto engine. The engine transforms async frames info sync crypto ops and delegates them to active sync engines. With the patch it is possible to increase the single worker crypto throughput by offloading the crypto workload to multiple workers. By default all workers in the system will attend the crypto workload processing. However a worker's available cycles are limited. To avail more cycles to one worker to process other workload (e.g. the worker core that handles the RX/TX and IPSec stack processing), a useful cli command is added to remove itself (or add it back later) from the heavy crypto workload but only let other workers to process the crypto. The command is: - set sw_scheduler worker <idx> crypto <on|off> It also adds new interrupt mode to async crypto dispatch node. This mode signals the node when new frames are enqueued as opposed to polling mode that continuously calls dispatch node. New cli commands: - set crypto async dispatch [polling|interrupt] - show crypto async status (displays mode and nodes' states) Signed-off-by: PiotrX Kleski <piotrx.kleski@intel.com> Signed-off-by: DariuszX Kazimierski <dariuszx.kazimierski@intel.com> Reviewed-by: Fan Zhang <roy.fan.zhang@intel.com> Change-Id: I332655f347bb9e3bc9c64166e86e393e911bdb39

In one's complement, there are two representations of zero: the all zero and the all one bit values, often referred to as +0 and -0. See RFC 1624 section 3 for more details. This used to be taken care of in ip4_header_checksum(), but it is no longer the case. The check ip->checksum == ip4_header_checksum (ip) is no longer correct in the -0 case. Always use ip4_header_checksum_is_valid() instead (which behaves correctly since 9a79a1ab931c3b5a7ae07d6f0fcfef7c4368a2c4).
