2021-10-12Revert "nat: static mappings in flow hash"Ole Troan1-56/+96
This reverts commit 69b7599e4b061a8996205f0304232ede84cb70d4. Type: fix Signed-off-by: Ole Troan <ot@cisco.com> Change-Id: If531b122ae5a9f91c2fe6eaa0da69922a91f16d3
2021-10-12nat: static mappings in flow hashKlement Sekera1-96/+56
Put static mappings in flow hash, drop existing hash tables used for static mappings. Drop refcount variables and use hash table as a single point of truth. Allow creating a static mapping conflicting with dynamic mapping, which will take precedence after dynamic mapping is freed, so that the existing flow can finish transferring data.

2021-06-16nat: test all intf addrs in is_interface_addr()Alexander Chernavin1-9/+19
Type: fix Currently, is_interface_addr() tests if a given IPv4 address belongs to an interface by a given sw_if_index. However, there are several issues: * only the first found address on the interface is actually tested, * sw_if_index is always cached even if the interface hasn't been assigned any addresses yet. With this change, is_interface_addr() tests all IPv4 addresses on an interface by a given sw_if_index and caches sw_if_index only if there are addresses present.

This patch achieves complete separation of endpoint-dependent and endpoint-independent IPv4 NAT features. Some common stuff is also moved to NAT library. Type: refactor Change-Id: I52468b7e2b5ac28958a2baf8e2ea01787322e801 Signed-off-by: Filip Varga <fivarga@cisco.com>
