v11: - drop SO_REUSEADDR setting in target: sockets closed in repair mode don't actually go to TIME_WAIT it seems - bind sockets to address too, and to the right flowside depending on whether they are for inbound or outbound connections - debug messages in flow_migrate_source() and flow_migrate_target() - error messages in tcp_flow_repair_queues() - set the same socket options (TCP_NODELAY, TCP_MAXSEG) just like for "regular" sockets, in tcp_flow_repair_socket() - connect() to HOSTFLOW(conn) flowside, not to TGTSIDE, in tcp_flow_repair_connect() - in test setup: set up guest_2 context in subshell - add migrate/bidirectional test David Gibson (4): fixup: Fix errors in modes that don't support migration migrate: Migrate guest observed addresses migrate: Hack for late migration fixups fixup: Reset SO_PEEK_OFF value after incoming migration Stefano Brivio (5): migrate: Skeleton of live migration logic Add interfaces and configuration bits for passt-repair vhost_user: Make source quit after reporting migration state migrate: Migrate TCP flows test: Add migration tests Makefile | 14 +- conf.c | 44 +++- epoll_type.h | 6 +- flow.c | 212 ++++++++++++++++ flow.h | 6 + migrate.c | 291 ++++++++++++++++++++++ migrate.h | 57 +++++ passt.1 | 11 + passt.c | 15 +- passt.h | 15 ++ repair.c | 192 +++++++++++++++ repair.h | 16 ++ tap.c | 65 +---- tcp.c | 483 +++++++++++++++++++++++++++++++++++++ tcp_conn.h | 60 +++++ test/lib/layout | 55 ++++- test/lib/setup | 128 ++++++++++ test/lib/test | 3 + test/migrate/basic | 54 +++++ test/migrate/bidirectional | 59 +++++ test/run | 7 + util.c | 62 +++++ util.h | 30 +++ vhost_user.c | 70 ++---- virtio.h | 4 - vu_common.c | 49 +--- vu_common.h | 2 +- 27 files changed, 1830 insertions(+), 180 deletions(-) create mode 100644 migrate.c create mode 100644 migrate.h create mode 100644 repair.c create mode 100644 repair.h create mode 100644 test/migrate/basic create mode 100644 test/migrate/bidirectional -- 2.43.0
