* Filter TCP connections to SO_REUSEPORT_LB listen sockets by NUMA domainAndrew Gallatin2020-12-191-1/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Switch to the BSDL grep implementation now that it's been a little more thoroughly tested and theoretically supports all of the extensions that gnugrep in base had with our libregex(3). Folks shouldn't really notice much from this update; bsdgrep is slower than gnugrep, but this is currently the price to pay for fewer bugs. Those dissatisfied with the speed of grep and in need of a faster implementation should check out what textproc/ripgrep and textproc/the_silver_searcher can do for them. I have some WIP to make bsdgrep faster, but do not consider it a blocker when compared to the pros of switching now (aforementioned bugs, licensing).

| | | | | | | | | | | | | | | | | | | | | | | | We are seeing regular build failures due to libc.so being installed again and another parallel make job tries to read the partially written libc.so at the same time. When building with -j32 or higher this almost always happens on the first clean build (subsequent incremental builds always work fine). Using -S should "fix" the "section header table goes past the end of the file: e_shoff = 0x..." errors that have started to plague our builds. We originally thought this only affected CheriBSD, but I just got the same error while building the latest upstream FreeBSD. The real fix should be to not install libraries twice, but until then this workaround is needed. Original patch by jrtc27@, I only made some minor changes to the comment.

* Remove the cloned file descriptors for /dev/crypto.John Baldwin2020-11-251-22/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | Crypto file descriptors were added in the original OCF import as a way to provide per-open data (specifically the list of symmetric sessions). However, this gives a bit of a confusing API where one has to open /dev/crypto and then invoke an ioctl to obtain a second file descriptor. This also does not match the API used with /dev/crypto on other BSDs or with Linux's /dev/crypto driver. Character devices have gained support for per-open data via cdevpriv since OCF was imported, so use cdevpriv to simplify the userland API by permitting ioctls directly on /dev/crypto descriptors. To provide backwards compatibility, CRIOGET now opens another /dev/crypto descriptor via kern_openat() rather than dup'ing the existing file descriptor. This preserves prior semantics in case CRIOGET is invoked multiple times on a single file descriptor.

| | | | | | | | | | | | | | | | | | | | | This removes 288KB (36%) of the driver code and zillions of hacks and workarounds, making single driver uniformly support several different generations of hardware interfaces, not counting minor card variations. After years of the hopeless fight, I don't think it worth to continue support for hardware obsolete for 15-20 years. Instead much cleaner now code should allow to move forward toward better locking, multiple queues and other cool features. All the remaining Qlogic cards starting from 4Gb 24xx to 32Gb 27xx use the same hardware/firmware interface with minor incremental improvements, so it seems to be a good new starting point. Except one PCI-X model all all of them are PCIe and so still usable in modern systems. Discussed with: ken, scottl, jpaetzel, imp Relnotes: yes Notes: svn path=/head/; revision=367857
