| | | | | | | | | | | | | | | | | | | | | | | | | | It turns out pf incorrectly updates the TCP checksum if the TCP option we're modifying is not 2-byte algined with respect to the start of the packet. Create a TCP packet with such an option and throw it through a scrub rule, which will update timestamps and modify the packet.

* | Improve address generation in the early arm64 bootAndrew Turner2020-12-231-11/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | The adr instruction allows for an address of +-1M from the instruction. If we replace these with an adrp and an add instruction we can generate an address +-4G. The adrp will get an address of the 4k page the label is within, and the add uses the :lo12: prefix to add just the low bits to this address. This will allow us to move things around with fewer issues than if we needed to keep them within the +-1MB range. Sponsored by: Innovate UK

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When tearing down a VNET, netgraph sends shutdown messages to all of the nodes before detaching interfaces (SI_SUB_NETGRAPH comes before SI_SUB_INIT_IF in teardown order). ng_ether nodes handle this by destroying themselves without detaching from the parent ifnet. Then, when ifnets go away they detach their ng_ether nodes again, triggering a use-after-free. Handle this by modifying ng_ether_shutdown() to detach from the ifnet. If the shutdown was triggered by an ifnet being destroyed, we will clear priv->ifp in the ng_ether detach callback, so priv->ifp may be NULL. Also get rid of the printf in vnet_netgraph_uninit(). It can be triggered trivially by ng_ether since ng_ether_shutdown() persists the node unless NG_REALLY_DIE is set.

* | Filter TCP connections to SO_REUSEPORT_LB listen sockets by NUMA domainAndrew Gallatin2020-12-197-35/+150
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to efficiently serve web traffic on a NUMA machine, one must avoid as many NUMA domain crossings as possible. With SO_REUSEPORT_LB, a number of workers can share a listen socket. However, even if a worker sets affinity to a core or set of cores on a NUMA domain, it will receive connections associated with all NUMA domains in the system. This will lead to cross-domain traffic when the server writes to the socket or calls sendfile(), and memory is allocated on the server's local NUMA node, but transmitted on the NUMA node associated with the TCP connection. Similarly, when the server reads from the socket, he will likely be reading memory allocated on the NUMA domain associated with the TCP connection. This change provides a new socket ioctl, TCP_REUSPORT_LB_NUMA. A server can now tell the kernel to filter traffic so that only incoming connections associated with the desired NUMA domain are given to the server. (Of course, in the case where there are no servers sharing the listen socket on some domain, then as a fallback, traffic will be hashed as normal to all servers sharing the listen socket regardless of domain). This allows a server to deal only with traffic that is local to its NUMA domain, and avoids cross-domain traffic in most cases. This patch, and a corresponding small patch to nginx to use TCP_REUSPORT_LB_NUMA allows us to serve 190Gb/s of kTLS encrypted https media content from dual-socket Xeons with only 13% (as measured by pcm.x) cross domain traffic on the memory controller.

* | Optionally bind ktls threads to NUMA domainsAndrew Gallatin2020-12-191-3/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When ktls_bind_thread is 2, we pick a ktls worker thread that is bound to the same domain as the TCP connection associated with the socket. We use roughly the same code as netinet/tcp_hpts.c to do this. This allows crypto to run on the same domain as the TCP connection is associated with. Assuming TCP_REUSPORT_LB_NUMA (D21636) is in place & in use, this ensures that the crypto source and destination buffers are local to the same NUMA domain as we're running crypto on. This change (when TCP_REUSPORT_LB_NUMA, D21636, is used) reduces cross-domain traffic from over 37% down to about 13% as measured by pcm.x on a dual-socket Xeon using nginx and a Netflix workload.
