fedeb08b6a58e708e1153224d37ad26bdc1062a2 - Introduce scalable route multipath.

Sat, 03 Oct 2020 12:47:17 +0200

Introduce scalable route multipath.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 1route add -6 2001:db8::/32 2001:db8::2 -weight 10route add -6 2001:db8::/32 2001:db8::3 -weight 20netstat -6OnNexthop groups dataInternet6:GrpIdx NhIdx Weight Slots Gateway Netif Refcnt1 ------- ------- ------- --------------------------------------- --------- 1 13 10 1 2001:db8::2 vlan2 14 20 2 2001:db8::3 vlan2Next 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 defaultTested by: olivierReviewed by: glebiusRelnotes: yesDifferential Revision: https://reviews.freebsd.org/D26449 List of files: /freebsd/usr.bin/netstat/Makefile

a666325282eaed4b044459d121f339b2d6d0224b - Introduce nexthop objects and new routing KPI.

Sun, 12 Apr 2020 16:30:00 +0200

Introduce nexthop objects and new routing KPI.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 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.More details:* architectural overview: https://reviews.freebsd.org/D24141* list of the next changes: https://reviews.freebsd.org/D24232Reviewed by: ae,glebius(initial version)Differential Revision: https://reviews.freebsd.org/D24232 List of files: /freebsd/usr.bin/netstat/Makefile

114350b9de8403b9e43bbad0d1534455a077d999 - Replace DPSRCS that work fine in SRCS.

Wed, 25 Nov 2015 21:38:17 +0100

Replace DPSRCS that work fine in SRCS.This is so that 'make depend' is not a required build step in thesefiles.DPSRCS is overall unneeded. DPSRCS already contains SRCS, so anythingwhich can safely be in SRCS should be. DPSRCS is mostly just a way togenerate files that should not be linked into the final PROG/LIB. Forheaders and grammars it is safe for them to be in SRCS since they willbe excluded during linking and installation.The only remaining uses of DPSRCS are for generating .c or .o files thatmust be built before 'make depend' can run 'mkdep' on the SRCS c fileslist. A semi-proper example is in tests/sys/kern/acct/Makefile where achecked-in .c file has an #include on a generated .c file. Thegenerated .c file should not be linked into the final PROG though sinceit is #include'd. The more proper way here is just to build/link it inthough without DPSRCS. Another example is in sys/modules/linux/Makefilewhere a shell script runs to parse a DPSRCS .o file that should not belinked into the module. Beyond those, the need for DPSRCS is largelyunneeded, redundant, and forces 'make depend' to be ran. Generally,these Makefiles should avoid the need for DPSRCS and define properdependencies for their files as well.An example of an improper usage and why this matters is in usr.bin/netstat.nl_defs.h was only in DPSRCS and so was not generated during 'make all',but only during 'make depend'. The files including it lacked properdepenencies on it, which forced running 'make depend' to workaround thatbug. The 'make depend' target should mostly be used for incremental buildhelp, not to produce a working build. This specific example was broken inthe meta build until r287905 since it does not run 'make depend'.The gnu/lib/libreadline/readline case is fine since bsd.lib.mk has 'OBJS:SRCS:M*.h' when there is no .depend file.Sponsored by: EMC / Isilon Storage DivisionMFC after: 1 week List of files: /freebsd/usr.bin/netstat/Makefile
