1Stress test bind(2) and connect(2) system calls in OpenBSD regress. 2 3bindconnect [-r] [-b bind] [-c connect] [-d delroute] [-f family] [-N addr/net] 4[-n num] [-o close] [-p proto] [-s socket] [-t time] 5 -b bind threads binding sockets, default 1 6 -c connect threads connecting sockets, default 1 7 -d delroute threads deleting cloned routes, default 0 8 -f family address family inet or inet6, default inet 9 -N addr/net connect to any address within network 10 -n num number of file descriptors, default 128 11 -o close threads closing sockets, default 1 12 -p proto protocol udp, tcp, name or number, default udp 13 -r set reuse port socket option 14 -s socket threads creating sockets, default 1 15 -t time run time in seconds, default 10 16 17Separate threads are started to run socket(2), close(2), bind(2), 18and connect(2) system calls concurrently. The number of sockets 19is controlled by the process limit of open file descriptors. All 20system calls operate on random file descriptors. By setting the 21number of threads for each system call and the number of available 22file descriptors, the focus for the stress test can be changed. 23 24Currently IPv4 and IPv6 UDP sockets are supported. Per default the 25address to bind and connect is 127.0.0.1 or ::1. LOCAL_NET or 26LOCAL_NET6 environment variable allows to bind on a local address 27and connect to all directly attached hosts. This triggers creation 28of cloned routes during source address selection. To stress test 29routing table, these routes can be deleted in another thread. 30
