2021-02-15vlib: refactor checksum offload supportMohsin Kazmi6-38/+39
Type: refactor This patch refactors the offload flags in vlib_buffer_t. There are two main reasons behind this refactoring. First, offload flags are insufficient to represent outer and inner headers offloads. Second, room for these flags in first cacheline of vlib_buffer_t is also limited. This patch introduces a generic offload flag in first cacheline. And detailed offload flags in 2nd cacheline of the structure for performance optimization.

2021-02-09crypto: fix bad-hmac in sw scheduler if async modeAlexander Chernavin1-0/+1
When IPsec async mode is enabled, packets don't pass through the tunnel if ciphers other than AES GCM are used for child SAs. An error that arises is "bad-hmac" in the "crypto-dispatch" node. On the encryption stage, the VNET_CRYPTO_OP_FLAG_HMAC_CHECK flag is set for the integrity crypto operation when it's not supposed to. It seems that the flag remains from the previous operation. With this change, zero flags of crypto operations in the SW scheduler during operation filling.

2021-02-09nat: deny adding intf addr if static-mapping-onlyAlexander Chernavin1-0/+8
If static-mapping-only is enabled, NAT pool cannot be configured, only static mappings. There're two ways to add addresses to the NAT pool: by address range, or by first found address from an interface. NAT44_ADD_DEL_ADDRESS_RANGE already tests if dynamic mappings are available but NAT44_ADD_DEL_INTERFACE_ADDR doesn't. If static-mapping-only is enabled, adding addresses by range is rejected but by interface not. With this change, if static-mapping-only is enabled, do not allow to add addresses to the NAT pool both ways.

This reverts commit c7eaa711f3e25580687df0618e9ca80d3dc85e5f. Reason for revert: The jenkins job named 'vpp-merge-master-ubuntu1804-x86_64' had 2 IPv6 AH tests fail after the change was merged.

2021-02-08tests: allow for externally supplied VPP workers config for testsAndrew Yourtchenko1-0/+2
Allow to supply the external VPP worker config for tests which do not specify the workers config explicitly, and use the tags infra to flag those that need attention in this configuration. This commit shows one example use of such a tag, there will be a separate commit with the rest of the places needing it, since that change is rather mechanical. Thus, the assumption is that the test should by default be agnostic of the VPP configuration, unless it explicitly specifies so.
