* Filter TCP connections to SO_REUSEPORT_LB listen sockets by NUMA domaingallatin2020-12-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 domainsgallatin2020-12-19
| | | | | | | | | | | | | | | | | | | | | | 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.

* rtld-elf: link udivmoddi4 from compiler_rtrlibby2020-12-19
| | | | | | | | | | | | | | | | | | | | | | | | | | This fixes the gcc9 build of rtld-elf32 on amd64, which needed an implementation of udivmoddi4. rtld-elf uses certain functions normally found in libc, and so it includes certain files from libc in its own build. It has two mechanisms to include files from libc: one that rebuilds source files in the rtld-elf environment, and one that extracts object files from a purpose-built no-SSP PIC archive. In addition to libc functions, rtld-elf may need to link functions normally found in libcompiler_rt (formerly libgcc). Now, add an ability to rebuild libcompiler_rt source files in the rtld-elf environment. We don't yet have a need for an object file extraction mechanism. libcompiler_rt could also supply udivdi3 and umoddi3, but leave them alone for now.

* kern: cpuset: allow jails to modify child jails' rootskevans2020-12-19
| | | | | | | | | | | | | | | | | | | | | | | This partially lifts a restriction imposed by r191639 ("Prevent a superuser inside a jail from modifying the dedicated root cpuset of that jail") that's perhaps beneficial after r192895 ("Add hierarchical jails."). Jails still cannot modify their own cpuset, but they can modify child jails' roots to further restrict them or widen them back to the modifying jails' own mask. As a side effect of this, the system root may once again widen the mask of jails as long as they're still using a subset of the parent jails' mask. This was previously prevented by the fact that cpuset_getroot of a root set will return that root, rather than the root's parent -- cpuset_modify uses cpuset_getroot since it was introduced in r327895, previously it was just validating against set->cs_parent which allowed the system root to widen jail masks.

In this case we were not coalescing the corresponding entries in the memory affinity table, which led to fragmented phys_avail[] entries. Since r338431 the vm_phys_segs[] entries derived from phys_avail[] will be coalesced, resulting in a situation where vm_phys_segs[] entries do not have a covering phys_avail[] entry. vm_page_startup() will not add such segments to the physical memory allocator, leaving them unused.
