2019-09-25lacp: mark is_mp_safe for show and dump binary APISteven Luong2-0/+5
show and dump binary APIs for lacp neighbors are running in the same thread as the create and delete interface. There is no need for barrier lock. Type: fix Signed-off-by: Steven Luong <sluong@cisco.com> Change-Id: Id584bd7408210fcc23b464ef2084f11f88bca58b (cherry picked from commit cda35b38d7b690a63a17967268e8c1339a16dfd2)
2019-09-20bonding lacp: deleting virtual interface which was enslaved may cause crashSteven Luong2-20/+27
Virtual interfaces may be part of the bonding like physical interfaces. The difference is virtual interfaces may disappear dynamically. As an example, the following CLI sequence may crash the debug image create vhost-user socket /tmp/sock1 create bond mode lacp bond add BondEthernet0 VirtualEthernet0/0/0 delete vhost-user VirtualEhernet0/0/0 Notice the virtual interface is deleted without first doing bond delete. The proper order is to first remove the slave interface from the bond prior to deleting the virtual interface as shown below. But we should handle it anyway. create vhost-user socket /tmp/sock1 create bond mode lacp bond add BondEthernet0 VirtualEthernet0/0/0 bond del VirtualEthernet0/0/0 <----- delete vhost-user VirtualEhernet0/0/0 The fix is to register for VNET_SW_INTERFACE_ADD_DEL_FUNCTION and remove the slave interface from the bond if the to-be-deleted interface is part of the bond. We check the interface that it is actually up before we send the lacp pdu. Up means both hw and sw admin up.

2019-07-09vat: unload unused vat pluginsDave Barach1-2/+4
If the corresponding vpp plugin is absent, return a non-zero clib_error_t * from vat_plugin_register ("xxx plugin not loaded"). The vat plugin calls dlclose on the vat plugin, and it disappears. Depending on the plugin configuration, this can reduce the vpp virtual size by several gigabytes. Added a VAT_PLUGIN(<plugin-name>) macro to vat_helper_macros, clean up boilerplate vat_plugin_register() implementations. Fixed a number of non-standard vat_plugin_register methods.

2019-05-16init / exit function orderingDave Barach1-6/+6
The vlib init function subsystem now supports a mix of procedural and formally-specified ordering constraints. We should eliminate procedural knowledge wherever possible. The following schemes are *roughly* equivalent: static clib_error_t *init_runs_first (vlib_main_t *vm) { clib_error_t *error; ... do some stuff... if ((error = vlib_call_init_function (init_runs_next))) return error; ... } VLIB_INIT_FUNCTION (init_runs_first); and static clib_error_t *init_runs_first (vlib_main_t *vm) { ... do some stuff... } VLIB_INIT_FUNCTION (init_runs_first) = { .runs_before = VLIB_INITS("init_runs_next"), }; The first form will [most likely] call "init_runs_next" on the spot. The second form means that "init_runs_first" runs before "init_runs_next," possibly much earlier in the sequence. Please DO NOT construct sets of init functions where A before B actually means A *right before* B. It's not necessary - simply combine A and B - and it leads to hugely annoying debugging exercises when trying to switch from ad-hoc procedural ordering constraints to formal ordering constraints.

2019-04-03lacp: passive mode support [VPP-1551]Steven Luong7-56/+124
By definition, passive mode means the node does not start sending lacp pdu until it first hears from the partner or remote. - Rename ptx machine's BEGIN state to NO_PERIODIC state. - Put periodic machine in NO_PERIDOIC state when the interface is enabled for lacp. ptx machine will transition out of NO_PERIODIC state when the local node hears from the remote or when the local node is configured for active mode. - Also add send and receive statistics for debugging.

2018-08-17lacp: issue with slave interface admin up after it is added to the bond groupSteven1-2/+2
When the slave interface is admin up after it is added to the bond group, lacp does not send lacp pdu's to the interface because its periodic timer is not running. The issue was the slave interface's variables got reset after the state machines were initialized. Change-Id: I2942556ce29a4acc97db3be40293e69bed7b6679 Signed-off-by: Steven <sluong@cisco.com>
2018-05-25bond: performance harvestingSteven1-7/+7
- 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.

2018-04-24lacp: deleting the bond subinterface may cause lacp to lose the partner ↵Steven2-15/+8
[VPP-1251] Problem: When the bond subinterface is removed, it was observed that we lost the lacp partner. Show hardware shows rx counter goes up, but show interface does not for the slave interfaces. Cause: We reset the interface promiscuous mode when the bond subinterface is deleted. This causes dpdk not to accept any packet. Leave the interface in promiscuous mode fixes the problem. Other fixes: There are few places we use hw_if_index as if they are sw_if_index. But they don't necessarily have the same value. As soon as a subinterface is created, they start to diverge. The fix is to use the correct API for the hw_if_index and sw_if_index.

2018-03-21bond: Add bonding driver and LACP protocolSteven22-0/+3943
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.
