Sat, 25 Apr 2026 03:14:18 +0200

Merge branch 'bpf-replace-min-max-fields-with-struct-cnum-32-64'Eduard Zingerman says:====================bpf: replace min/max fields with struct cnum{32,64}This RFC replaces s64, u64, s32, u32 scalar range domains tracked byverifier by a pair of circular numbers (cnums): one for 64-bit domainand another for 32-bit domain. Each cnum represents a range as asingle arc on the circular number line, from which signed and unsignedbounds are derived on demand. See also wrapped intervalsrepresentation as in [1].The use of such representation simplifies arithmetic and conditionshandling in verifier.c and allows to express 32 <-> 64 bit deductionsin a more mathematically rigorous way.[1] https://jorgenavas.github.io/papers/ACM-TOPLAS-wrapped.pdfChangelog=========v2 -> v1:- Fixes in source code comments highlighted by bot+bpf-ci.RFCv1 -> v2:- Dropped RFC tag.- Dropped cnum{32,64}_mul(), too much complexity and no veristat or selftests gains.- cnum32_from_cnum64() normalizes to CNUM32_EMPTY when input cnum64.size >= U32_MAX, previously only checked for > U32_MAX (bot+bpf-ci).- cnum32_from_cnum64() and cnum64_cnum32_intersect() now check for empty inputs (sashiko).- In regs_refine_cond_op() case BPF_JSLT use cnum{32,64}_from_srange constructors instead of unsigned variants (sashiko).- cnum{32,64}_intersect_with{,_urange,_srange}() helpers added (Alexei)[RFCv1] https://lore.kernel.org/bpf/0c47b0b7ea476647746806c46fded4353be885f7.camel@gmail.com/T/[v2] https://lore.kernel.org/bpf/c4fb60bafd526ae2d92b86e2250255aef0ba5ee1.camel@gmail.com/T/Patch set layout================Patch #1 introduces the cnum (circular number) data type and basicoperations: intersection, addition, multiplication, negation, 32-to-64and 64-to-32 projections.CBMC based proofs for these operations are available at [2].(The proofs lag behind the current patch set and need an update ifthis RFC moves further. Although, I don't expect any significantchanges).[2] https://github.com/eddyz87/cnum-verifPatch #2 mechanically converts all direct accesses to bpf_reg_state'smin/max fields to use accessor functions, preparing for the fieldreplacement.Patch #3 replaces the eight independent min/max fields inbpf_reg_state with two cnum fields. The signed and unsigned bounds arederived on demand from the cnum via the accessor functions.This eliminates the separate signed<->unsigned cross-deduction logic,simplifies reg_bounds_sync(), regs_refine_cond_op() and somearithmetic operations.Patch #4 adds selftest cases for improved 32->64 range refinementsenabled by cnum64_cnum32_intersect().Precision trade-offs====================A cnum represents a contiguous arc on the circular number line.Current master tracks four independent ranges (s64, u64, s32, u32)whose intersection could implicitly represent value sets that aretwo disjoint arcs on the circle - something a single cnum cannot.Cnums lose precision when a cross-domain conditional comparison(e.g., unsigned comparison on a register with a signed-derived range)produces an intersection that would be two disjoint arcs.The cnum must over-approximate by returning one of the input arcs.E.g. a pair of ranges u64:[1,U64_MAX] s:[-1,1] represents a set of twovalues: {-1,1}, this can only be approximated as a set of three valuesby cnum: {-1,0,1}.Cnums gain precision in arithmetic: when addition, subtraction ormultiplication causes register value to cross both signed and unsignedmin/max boundaries. Current master resets the register as unbound insuch cases, while cnums preserve the exact wrapping arc.In practice precision loss turned out to matter only for a set ofspecifically crafted selftests from reg_bounds.c (see patch #3 formore details). On the other hand, precision gains are observable for aset real-life programs.Verification performance measurements=====================================Tested on 6683 programs across four corpora: Cilium (134 programs),selftests (4635), sched_ext (376), and Meta internal BPF corpus(1540). Program verification verdicts are identical across all fourprogram sets - no program changes between success and failure.Instruction count comparison (cnum vs signed/unsigned pair):- 83 programs improve, 44 regress, 6596 unchanged- Total saved: ~290K insns, total added: 10K insns- Largest improvements: -26% insns in a internal network firewall program; -47% insns in rusty/wd40 sched_ext schedulers.- Largest regression: +24% insns in one Cilium program (5062 insns added).Raw performance data is at the bottom of the email.Raw verification performance metrics====================================Filtered out by -f insns_pct>5 -f !insns<10000========= selftests: master vs cnums-everywhere-v2 =========File Program Insns (A) Insns (B) Insns (DIFF)---- ------- --------- --------- ------------Total progs: 4665total_insns diff min: -15.71%total_insns diff max: 45.45% -20 .. -10 %: 3 -5 .. 0 %: 6 0 .. 5 %: 4654 45 .. 50 %: 2========= scx: master vs cnums-everywhere-v2 =========File Program Insns (A) Insns (B) Insns (DIFF)--------------- -------------- --------- --------- ----------------scx_rusty.bpf.o rusty_enqueue 39842 22053 -17789 (-44.65%)scx_rusty.bpf.o rusty_stopping 37738 19949 -17789 (-47.14%)scx_wd40.bpf.o wd40_stopping 37729 19880 -17849 (-47.31%)Total progs: 376total_insns diff min: -47.31%total_insns diff max: 19.61% -50 .. -40 %: 3 -5 .. 0 %: 5 0 .. 5 %: 366 5 .. 15 %: 1 15 .. 20 %: 1========= meta: master vs cnums-everywhere-v2 =========File Program Insns (A) Insns (B) Insns (DIFF)--------------------------------- ---------- --------- --------- ---------------- ...egress 222327 164648 -57679 (-25.94%) ..._tc_eg 222839 164772 -58067 (-26.06%) ...egress 222327 164648 -57679 (-25.94%) ..._tc_eg 222839 164772 -58067 (-26.06%)Total progs: 1540total_insns diff min: -26.06%total_insns diff max: 6.69% -30 .. -20 %: 4 -15 .. -5 %: 6 -5 .. 0 %: 36 0 .. 5 %: 1493 5 .. 10 %: 1========= cilium: master vs cnums-everywhere-v2 =========File Program Insns (A) Insns (B) Insns (DIFF)---------- ------------------------------- --------- --------- ---------------bpf_host.o tail_handle_ipv4_cont_from_host 20962 26024 +5062 (+24.15%)bpf_host.o tail_handle_ipv6_cont_from_host 17036 18672 +1636 (+9.60%)Total progs: 134total_insns diff min: -3.32%total_insns diff max: 24.15% -5 .. 0 %: 12 0 .. 5 %: 120 5 .. 15 %: 1 20 .. 25 %: 1---====================Link: https://patch.msgid.link/20260424-cnums-everywhere-rfc-v1-v3-0-ca434b39a486@gmail.comSigned-off-by: Alexei Starovoitov List of files: /linux/kernel/bpf/Makefile

Sat, 25 Apr 2026 00:52:42 +0200

bpf: representation and basic operations on circular numbersThis commit adds basic definitions for cnum32/cnum64.This is a unified numeric range representation for signed and unsigneddomains. Inspired by an old post from Shung-Hsi Yu [1] and paper [2].Operations correctness is verified using cbmc model checker,tests source code can be found in a separate repo [3].The cnum64_cnum32_intersect() function is notable, because it handledseveral cases verifier.c:deduce_bounds_64_from_32() does not.Given:- a is a 64-bit range- b is a 32-bit range- t is a refined 64-bit range, such that ∀ v ∈ a, (u32)v ∈ b: v ∈ t.cnum64_cnum32_intersect() makes the following deductions:(A): 'b' is a sub-range of the first or the last 32-bit sub-range of 'a': 64-bit number axis ---> N*2^32 (N+1)*2^32 (N+2)*2^32 (N+3)*2^32 ||------|---|=====|-------||----------|=====|-------||----------|=====|----|--|| | || || || | | | | | |<--+--------------------------- a ---------------------------+--->| | | |<-------------------------- t -------------------------->|(B) 'b' does not intersect with the first of the last 32-bit sub-range of 'a':N*2^32 (N+1)*2^32 (N+2)*2^32 (N+3)*2^32||--|=====|----|----------||--|=====|---------------||--|=====|------------|--|| || | || || | | | | | |<-------------+--------- a -------------------|----------->| | | |<-------- t ------------------>|(C) 'b' crosses 0/U32_MAX boundary:N*2^32 (N+1)*2^32 (N+2)*2^32 (N+3)*2^32||===|---------|------|===||===|----------------|===||===|---------|------|===|| |b >| | |< b||b >| |< b||b >| | |< b| | | | | |<-----+----------------- a --------------+-------->| | | |<---------------- t ------------->|Current implementation of deduce_bounds_64_from_32() only handlescase (A).[1] https://lore.kernel.org/all/ZTZxoDJJbX9mrQ9w@u94a/[2] https://jorgenavas.github.io/papers/ACM-TOPLAS-wrapped.pdf[3] https://github.com/eddyz87/cnum-verif/tree/masterSigned-off-by: Eduard Zingerman Link: https://lore.kernel.org/r/20260424-cnums-everywhere-rfc-v1-v3-1-ca434b39a486@gmail.comSigned-off-by: Alexei Starovoitov List of files: /linux/kernel/bpf/Makefile
