| | | | | | | | | | | | | | | Avoid POLA breakage and preserve output standard that really predates the FreeBSD project itself. There are scripts in the wild that rely on the behavior. Provide option to specify -nn twice to have a completely numeric output of the routing tables.

* Introduce scalable route multipath.Alexander V. Chernikov2020-10-031-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change is based on the nexthop objects landed in D24232. The change introduces the concept of nexthop groups. Each group contains the collection of nexthops with their relative weights and a dataplane-optimized structure to enable efficient nexthop selection. Simular to the nexthops, nexthop groups are immutable. Dataplane part gets compiled during group creation and is basically an array of nexthop pointers, compiled w.r.t their weights. With this change, `rt_nhop` field of `struct rtentry` contains either nexthop or nexthop group. They are distinguished by the presense of NHF_MULTIPATH flag. All dataplane lookup functions returns pointer to the nexthop object, leaving nexhop groups details inside routing subsystem. User-visible changes: The change is intended to be backward-compatible: all non-mpath operations should work as before with ROUTE_MPATH and net.route.multipath=1. All routes now comes with weight, default weight is 1, maximum is 2^24-1. Current maximum multipath group width is statically set to 64. This will become sysctl-tunable in the followup changes. Using functionality: * Recompile kernel with ROUTE_MPATH * set net.route.multipath to 1 route add -6 2001:db8::/32 2001:db8::2 -weight 10 route add -6 2001:db8::/32 2001:db8::3 -weight 20 netstat -6On Nexthop groups data Internet6: GrpIdx NhIdx Weight Slots Gateway Netif Refcnt 1 ------- ------- ------- --------------------------------------- --------- 1 13 10 1 2001:db8::2 vlan2 14 20 2 2001:db8::3 vlan2 Next steps: * Land outbound hashing for locally-originated routes ( D26523 ). * Fix net/bird multipath (net/frr seems to work fine) * Add ROUTE_MPATH to GENERIC * Set net.route.multipath=1 by default Tested by: olivier Reviewed by: glebius Relnotes: yes Differential Revision: https://reviews.freebsd.org/D26449 Notes: svn path=/head/; revision=366390

* Introduce nexthop objects and new routing KPI.Alexander V. Chernikov2020-04-121-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the foundational change for the routing subsytem rearchitecture. More details and goals are available in https://reviews.freebsd.org/D24141 . This patch introduces concept of nexthop objects and new nexthop-based routing KPI. Nexthops are objects, containing all necessary information for performing the packet output decision. Output interface, mtu, flags, gw address goes there. For most of the cases, these objects will serve the same role as the struct rtentry is currently serving. Typically there will be low tens of such objects for the router even with multiple BGP full-views, as these objects will be shared between routing entries. This allows to store more information in the nexthop. New KPI: struct nhop_object *fib4_lookup(uint32_t fibnum, struct in_addr dst, uint32_t scopeid, uint32_t flags, uint32_t flowid); struct nhop_object *fib6_lookup(uint32_t fibnum, const struct in6_addr *dst6, uint32_t scopeid, uint32_t flags, uint32_t flowid); These 2 function are intended to replace all all flavours of <in_|in6_>rtalloc[1]<_ign><_fib>, mpath functions and the previous fib[46]-generation functions. Upon successful lookup, they return nexthop object which is guaranteed to exist within current NET_EPOCH. If longer lifetime is desired, one can specify NHR_REF as a flag and get a referenced version of the nexthop. Reference semantic closely resembles rtentry one, allowing sed-style conversion. Additionally, another 2 functions are introduced to support uRPF functionality inside variety of our firewalls. Their primary goal is to hide the multipath implementation details inside the routing subsystem, greatly simplifying firewalls implementation: int fib4_lookup_urpf(uint32_t fibnum, struct in_addr dst, uint32_t scopeid, uint32_t flags, const struct ifnet *src_if); int fib6_lookup_urpf(uint32_t fibnum, const struct in6_addr *dst6, uint32_t scopeid, uint32_t flags, const struct ifnet *src_if); All functions have a separate scopeid argument, paving way to eliminating IPv6 scope embedding and allowing to support IPv4 link-locals in the future. Structure changes: * rtentry gets new 'rt_nhop' pointer, slightly growing the overall size. * rib_head gets new 'rnh_preadd' callback pointer, slightly growing overall sz. Old KPI: During the transition state old and new KPI will coexists. As there are another 4-5 decent-sized conversion patches, it will probably take a couple of weeks. To support both KPIs, fields not required by the new KPI (most of rtentry) has to be kept, resulting in the temporary size increase. Once conversion is finished, rtentry will notably shrink.

* Add the "TCP Blackbox Recorder" which we discussed at the developerJonathan T. Looney2018-03-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | summits at BSDCan and BSDCam in 2017. The TCP Blackbox Recorder allows you to capture events on a TCP connection in a ring buffer. It stores metadata with the event. It optionally stores the TCP header associated with an event (if the event is associated with a packet) and also optionally stores information on the sockets. It supports setting a log ID on a TCP connection and using this to correlate multiple connections that share a common log ID. You can log connections in different modes. If you are doing a coordinated test with a particular connection, you may tell the system to put it in mode 4 (continuous dump). Or, if you just want to monitor for errors, you can put it in mode 1 (ring buffer) and dump all the ring buffers associated with the connection ID when we receive an error signal for that connection ID. You can set a default mode that will be applied to a particular ratio of incoming connections. You can also manually set a mode using a socket option. This commit includes only basic probes. rrs@ has added quite an abundance of probes in his TCP development work. He plans to commit those soon. There are user-space programs which we plan to commit as ports. These read the data from the log device and output pcapng files, and then let you analyze the data (and metadata) in the pcapng files.

* Rewrite netstat/if.c to use getifaddrs(3) and getifmaddrs(3) instead ofGleb Smirnoff2013-10-151-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | libkvm digging in kernel memory. This is possible since r231506 made getifaddrs(3) to supply if_data for each ifaddr. The pros of this change is that now netstat(1) doesn't know about kernel struct ifnet and struct ifaddr. And these structs are about to change significantly in head soon. New netstat binary will work well with 10.0 and any future kernel. The cons is that now it isn't possible to obtain interface statistics from a vmcore. Functions intpr() and sidewaysintpr() were rewritten from scratch. The output of netstat(1) has underwent the following changes: 1) The MTU is not printed for protocol addresses, since it has no notion. Dash is printed instead. If there would be a strong desire to return previous output, it is doable. 2) Output interface queue drops are not printed. Currently this data isn't available to userland via any API. We plan to drop 'struct ifqueue' from 'struct ifnet' very soon, so old kvm(3) access to queue drops is soon to be broken, too. The plan is that drivers would handle their queues theirselves and a new field in if_data would be updated in case of drops. 3) In-kernel reference count for multicast addresses isn't printed. I doubt that anyone used it. Anyway, netstat(1) is sysadmin tool, not kernel debugger. Sponsored by: Netflix Sponsored by: Nginx, Inc. Notes: svn path=/head/; revision=256512

Don't build our own timer abstractions when ratecheck() and timevalclear() etc will do. * Expose the multicast forwarding cache (MFC) and virtual interface table (VIF) as sysctls, to reduce netstat's dependence on libkvm for this information for running kernels. * bandwidth meters however still require libkvm. * Make the MFC hash table size a boot/load-time tunable ULONG, net.inet.ip.mfchashsize (defaults to 256). * Remove unused members from struct vif and struct mfc. * Kill RSVP support, as no current RSVP implementation uses it. These stubs could be moved to raw_ip.c. * Don't share locks or initialization between IPv4 and IPv6. * Don't use a static struct route_in6 in ip6_mroute.c. The v6 code is still using a cached struct route_in6, this is moved to mif6 for the time being. * More cleanup remains to be merged from ip_mroute.c to ip6_mroute.c. v4 path tested using ports/net/mcast-tools. v6 changes are mostly mechanical locking and *have not* been tested.

* Restore netstat -M functionality for most statistics on core dumps. InJohn Baldwin2007-07-161-38/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | general, when support was added to netstat for fetching data using sysctl, no provision was left for fetching equivalent data from a core dump, and in fact, netstat would _always_ fetch data from the live kernel using sysctl even when -M was specified resulting in the user believing they were getting data from coredumps when they actually weren't. Some specific changes: - Add a global 'live' variable that is true if netstat is running against the live kernel and false if -M has been specified. - Stop abusing the sysctl flag in the protocol tables to hold the protocol number. Instead, the protocol is now its own field in the tables, and it is passed as a separate parameter to the PCB and stat routines rather than overloading the KVM offset parameter. - Don't run PCB or stats functions who don't have a namelist offset if we are being run against a crash dump (!live). - For the inet and unix PCB routines, we generate the same buffer from KVM that the sysctl usually generates complete with the header and trailer. - Don't run bpf stats for !live (before it would just silently always run live). - kread() no longer trashes memory when opening the buffer if there is an error on open and the passed in buffer is smaller than _POSIX2_LINE_MAX. - The multicast routing code doesn't fallback to kvm on live kernels if the sysctl fails. Keeping this made the code rather hairy, and netstat is already tied to the kernel ABI anyway (even when using sysctl's since things like xinpcb contain an inpcb) so any kernels this is run against that have the multicast routing stuff should have the sysctls. - Don't try to dig around in the kernel linker in the netgraph PCB routine for core dumps. Other notes: - sctp's PCB routine only works on live kernels, it looked rather complicated to generate all the same stuff via KVM. Someone can always add it later if desired though. - Fix the ipsec removal bug where N_xxx for IPSEC stats weren't renumbered. - Use sysctlbyname() everywhere rather than hardcoded mib values.
