Replace the offset-based approach for tracking progress through a bucket in the UDP table with one based on unique, monotonically increasing index numbers associated with each socket in a bucket. Signed-off-by: Jordan Rife <[email protected]>
Replace the offset-based approach for tracking progress through a bucket in the TCP table with one based on unique, monotonically increasing index numbers associated with each socket in a bucket. Signed-off-by: Jordan Rife <[email protected]>
Add do_skip_test() and do_repeat_test() subtests to the sock_iter_batch prog_test to check for socket skips and repeats, respectively. Extend the sock_iter_batch BPF program to output the socket cookie as well, so that we can check for uniqueness. The skip test works by partially iterating through a bucket, then closing one of the sockets that have already been seen to remove it from the bucket. Before, this would have resulted in skipping the fourth socket. Now, the fourth socket is seen. The repeat test works by partially iterating through a bucket, then adding four more sockets to the head of the bucket. Before, this would have resulted in repeating several of the sockets from the first batch, but now we see sockets exactly once. Signed-off-by: Jordan Rife <[email protected]>
