In qemu-1.4.x, When performing migrate_cancel on hmp, Sometimes s->state is incorrrectly saved to MIG_STATE_ERROR instead of MIG_STATE_CANCELLED. If the migrate_fd_cancel in main thread is scheduled to run before the thread buffered_file_thread calls migrate_fd_put_buffer, The s->state will be modified to MIG_STATE_CANCELLED by main thread, Then the migrate_fd_put_buffer in thread buffered_file_thread will return -EIO if s->state != MIG_STATE_ACTIVE, This incorrect return value trigged migrate_fd_error to set s->state = MIG_STATE_ERROR. This patch fixes the issue in qemu-1.4.x. Signed-off-by: Lin Ma <lma@suse.com> --- migration.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
