2023-07-13lb: Fix src_ip_sticky evaluation bug in per-port-vip case.Nobuhiro MIKI1-69/+8
Before this fix, the src_ip_sticky flag was passed as an argument to the lb_node_get_hash function, which computes a hash value for a packet. However, in per-port-vip case, the value of src_ip_sticky flag may be different for each port number. As a result, the value is the same for all port numbers, even though it is a per-port-vip case. This commit fixes the src_ip_sticky evaluation by delaying it until the packet is received, so that the correct value is obtained. Also, the unit test case has been enhanced for this bug fix. The steps to reproduce this bug are described below: https://lists.fd.io/g/vpp-dev/message/23248 Type: fix Fixes: 613e6dc0bf92 ("lb: add source ip based sticky load balancing") Change-Id: I483492b214a1768e7a21fd86edd5151b3c46528b Signed-off-by: Nobuhiro MIKI <nmiki@yahoo-corp.jp>
2023-01-18lb: add source ip based sticky load balancingNobuhiro MIKI1-9/+76
This patch adds source ip based sticky session, which is already implemented in many hardware LBs and software LBs. Note that sticky sessions may be reset if the hash is recalculated as ASs are added or deleted. Since this feature is unrelated to the other existing options, the lb_add_del_vip API version has been upgraded to v2 and a new option "src_ip_sticky" has been added.

2019-07-31vppinfra: refactor test_and_set spinlocks to use clib_spinlock_tjaszha031-1/+2
Spinlock performance improved when implemented with compare_and_exchange instead of test_and_set. All instances of test_and_set locks were refactored to use clib_spinlock_t when possible. Some locks e.g. ssvm synchronize between processes rather than threads, so they cannot directly use clib_spinlock_t.

L3DSR is used to overcome Layer 2 limitations of Direct Server Return Load Balancing. It maps VIP to DSCP bits, and reuse TOS bits to transfer it to server, and then server will get VIP from DSCP-to-VIP mapping.
