2020-07-28bonding: toggle bond admin state may cause hw link state to downSteven Luong1-2/+37
For bond interface, we set hardware link state to up initially when admin state is set to up. Thereafter, if we toggle the admin state to down and up, we require at least one active member in the bond prior to bringing up the hardware state which is inconsistent. The fix is to remove the unnecessary condition. This is a rework of the original proposed patch which is more complex and could be tricky to get it right https://gerrit.fd.io/r/c/vpp/+/27141 Type: fix Signed-off-by: Steven Luong <sluong@cisco.com> Change-Id: I65f4fee55299b5b4d5645f6e05e1be15b46b73cd

2020-05-27bonding: adjust link state based on active slavesMatthew Smith1-1/+58
Type: improvement Bond link state is being maintained inconsistently. It is initially set to up. If the bond interface admin state is set to down, the link state is set to down. If the bond interface admin state is set to up, the link state is only set to up if there are active slave interfaces at that point. If slaves become active at some later time, it does not get updated. Its next chance to be updated is the next time the bond interface is set to admin up. To address this, do not set the link state to up after creating a bond. Adjust the link state as slave interfaces are attached or detached based on whether the bond is getting its first active slave or losing its last one. Unit test added to verify correct maintenance of link state. Change-Id: I31f17321f7f0e727e1ab1e01713423af6566dad9 Signed-off-by: Matthew Smith <mgsmith@netgate.com>
2020-02-05stats: fix state counter removalVladimir Isaev1-40/+41
Avoid using vec_del1() for directory vector to keep indexes valid all the time. There are state counters for each slave in LACP bond mode which can be dynamically created and removed. Vector index is used to access these counters. But also vec_del1() is used to remove counter from vector. This function changes the index of the last element, so after this we are unable to access ex-last element using old index. As a result it is not possible to add-del-add two interfaces to the LACP bond: DBGvpp# create bond mode lacp BondEthernet0 DBGvpp# create packet-generator interface pg1 DBGvpp# create packet-generator interface pg2 DBGvpp# bond add BondEthernet0 pg1 DBGvpp# bond add BondEthernet0 pg2 DBGvpp# bond del pg1 DBGvpp# bond del pg2 DBGvpp# bond add BondEthernet0 pg1 DBGvpp# bond add BondEthernet0 pg2 bond add: /if/lacp/1/3/partner-state is already register Type: fix Signed-off-by: Vladimir Isaev <visaev@netgate.com> Change-Id: I2c86e13905eefdef6233369cd4ab5c1b53d123bd

2019-09-06bonding: add weight support for active-backup modeSteven Luong1-6/+3
Not all interfaces have the same characteristics within the bonding group. For active-backup mode, we should do our best to select the slave that performs the best as the primary slave. We already did that by preferring the slave that is local numa. Sometimes, this is not enough. For example, when all are local numas, the selection is arbitrary. Some slave interfaces may have higher speed or better qos than the others. But this is hard to infer. One rule does not fit all. So we let the operator to optionally specify the weight for each slave interface. Our primary slave selection rule is now 1. biggest weight 2. is local numa 3. current primary slave (to avoid churn) 4. lowest sw_if_index (for deterministic behavior) This selection rule only applies to active-backup mode which only one slave is used for forwarding traffic until it becomes unreachable. At that time, the next "best" slave candidate is automatically promoted. The slaves are sorted according to the preference rule when they are up. So there is no need to find the next best candidate when the primary slave goes down. Another good thing about this rule is when the down slave comes back up, it is selected as the primary slave again unless there is indeed a "better" slave than this down slave that were added during that period. To set the weight for the slave interface, do this after the interface is enslaved set interface bond <interface-name> weight <value> Type: feature Signed-off-by: Steven Luong <sluong@cisco.com> Change-Id: I59ced6d20ce1dec532e667dbe1afd1b4243e04f9

2018-05-25bond: performance harvestingSteven1-11/+3
- hash is great. But it is a bit too slow for the DP. Use direct array indexing to quickly retrieve the slave interface. - the algorithm used by flow hash is great. But it is a bit too slow for the DP. Use l2_hash_hash() extracted from lb_hash.h which ECMP is using. It makes use of intrinsic crc32 instruction set. - shortcut modulo arithmetic when the operand is 2**x (where x up to 4) to avoid division instruction. - special case for link count == 1 in bond_tx_fn() - use clib_mem_unaligned to access data for the packet to avoid alignment error - Fix some typos for packet tracing.

2018-03-21bond: Add bonding driver and LACP protocolSteven1-0/+282
Add bonding driver to support creation of bond interface which composes of multiple slave interfaces. The slave interfaces could be physical interfaces, or just any virtual interfaces. For example, memif interfaces. The syntax to create a bond interface is create bond mode <lacp | xor | acitve-backup | broadcast | round-robin> To enslave an interface to the bond interface, enslave interface TenGigabitEthernet6/0/0 to BondEthernet0 Please see src/plugins/lacp/lacp_doc.md for more examples and additional options. LACP is a control plane protocol which manages and monitors the status of the slave interfaces. The protocol is part of 802.3ad standard. This patch implements LACPv1. LACPv2 is not supported. To enable LACP on the bond interface, specify "mode lacp" when the bond interface is created. The syntax to enslave a slave interface is the same as other bonding modes.
