In AB bonding, if the current active slave becomes disabled, a replacement slave is arbitrarily picked from the remaining set of enabled slaves. This commit adds the concept of a "primary" slave: an interface that will always be (or become) the current active slave if it is enabled.
The rationale for this functionality is to allow the designation of a preferred interface for a given bond. For example: 1. Bond is created with interfaces p1 (primary) and p2, both enabled. 2. p1 becomes the current active slave (because it was designated as the primary). 3. Later, p1 fails/becomes disabled. 4. p2 is chosen to become the current active slave. 5. Later, p1 becomes re-enabled. 6. p1 is chosen to become the current active slave (because it was designated as the primary) Note that p1 becomes the active slave once it becomes re-enabled, even if nothing has happened to p2. This "primary" concept exists in Linux kernel network interface bonding, but did not previously exist in OVS bonding. Only one primary slave inteface is supported per bond, and is only supported for active/backup bonding. The primary slave interface is designated via "other_config:bond-primary" when creating a bond. Also, while adding tests for the "primary" concept, make a few small improvements to the non-primary AB bonding test.

Fix use of {}. v5: - Handle when bond is reconfigured to remove "bond-primary" config. - Fix potential flapping between remaining slaves. - Add a test to re-add a removed primary interface and make sure the bond reflects that properly. - Add a test to remove "bond-primary" config and make sure the bond reflects that properly. v4: - Style: bleep bloop. Trim line length below 79 characters. v3: - Adjusted print logic for when the primary slave is not attached v2: - Added "ovs-vsctl bond/show" label when primary interface is no longer enslaved - Fixed strcmp() usage nits - Moved "other_config:bond-primary" docs to the "Bonding Configuration" group - Expanded commit message - Added more test cases (including one for when the primary interface is no longer enslaved) ofproto/bond.c | 87 ++++++++++++++-- ofproto/bond.h | 1 + tests/lacp.at | 9 ++ tests/ofproto-dpif.at | 224 +++++++++++++++++++++++++++++++++++++++--- vswitchd/bridge.c | 5 + vswitchd/vswitch.xml | 8 ++ 6 files changed, 313 insertions(+), 21 deletions(-) diff --git a/ofproto/bond.c b/ofproto/bond.c index 9947e7531..4e634e2ce 100644 --- a/ofproto/bond.c +++ b/ofproto/bond.c @@ -89,6 +89,7 @@ struct bond_slave { /* Link status. */ bool enabled; /* May be chosen for flows? */ bool may_enable; /* Client considers this slave bondable. */ + bool is_primary; /* This slave is preferred over others. */ long long delay_expires; /* Time after which 'enabled' may change. */ /* Rebalancing info.
