v2->v3: fixed issues in backtracking pointed out by Andrii.
The next step is to add a lot more tests for backtracking.

v1->v2: addressed Andrii's feedback.

this patch set introduces verifier support for bounded loops and
adds several other improvements.
Ideally they would be introduced one at a time,
but to support bounded loop the verifier needs to 'step back'
in the patch 1. That patch introduces tracking of spill/fill
of constants through the stack. Though it's a useful feature
it hurts cilium tests.
Patch 3 introduces another feature by extending is_branch_taken
logic to 'if rX op rY' conditions. This feature is also
necessary to support bounded loops.
Then patch 4 adds support for the loops while adding
key heuristics with jmp_processed.
Introduction of parentage chain of verifier states in patch 4
allows patch 9 to add backtracking of precise scalar registers
which finally resolves degradation from patch 1.

The end result is much faster verifier for existing programs
and new support for loops.
See patch 8 for many kinds of loops that are now validated.
Patch 9 is the most tricky one and could be rewritten with
a different algorithm in the future.

Compilers often spill induction variables into the stack,
hence it is necessary for the verifier to track scalar values
of the registers through stack slots.

Also few bpf programs were incorrectly rejected in the past,
since the verifier was not able to track such constants while
they were used to compute offsets into packet headers.

Tracking constants through the stack significantly decreases
the chances of state pruning, since two different constants
are considered to be different by state equivalency.
End result that cilium tests suffer serious degradation in the number
of states processed and corresponding verification time increase.

                     before  after
bpf_lb-DLB_L3.o      1838    6441
bpf_lb-DLB_L4.o      3218    5908

bpf_overlay.o        6184    18561
bpf_lxc_jit.o        39389   359445

After further debugging turned out that cillium progs are
getting hurt by clang due to the same constant tracking issue.
Newer clang generates better code by spilling less to the stack.
Instead it keeps more constants in the registers which
hurts state pruning since the verifier already tracks constants
in the registers:
                  old clang  new clang
                         (no spill/fill tracking introduced by this patch)
bpf_lb-DLB_L3.o      1838    1923
bpf_lb-DLB_L4.o      3218    3077

bpf_netdev.o         9721    8407
bpf_overlay.o        6184    5420
bpf_lcx_jit.o        39389   39389

The final table is depressing:
                  old clang  old clang    new clang  new clang
                           const spill/fill        const spill/fill
bpf_lb-DLB_L3.o      1838    6441          1923      8128

bpf_lb-DUNKNOWN.o    1064    1064          1062      1062
bpf_lxc-DDROP_ALL.o  26935   93790         166729    380712
bpf_lxc-DUNKNOWN.o   34439   123886        174607    440652
bpf_netdev.o         9721    31413         8407      31904
bpf_overlay.o        6184    18561         5420      23569
bpf_lxc_jit.o        39389   359445        39389     359445

Tracking constants in the registers hurts state pruning already.
Adding tracking of constants through stack hurts pruning even more.
The later patch address this general constant tracking issue
with coarse/precise logic.

This patch extends is_branch_taken() logic from JMP+K instructions
to JMP+X instructions.
Conditional branches are often done when src and dst registers
contain known scalars. In such case the verifier can follow
the branch that is going to be taken when program executes.
That speeds up the verification and is essential feature to support
bounded loops.

Allow the verifier to validate the loops by simulating their execution.
Exisiting programs have used '#pragma unroll' to unroll the loops
by the compiler. Instead let the verifier simulate all iterations
of the loop.
In order to do that introduce parentage chain of bpf_verifier_state and
'branches' counter for the number of branches left to explore.
See more detailed algorithm description in bpf_verifier.h

This algorithm borrows the key idea from Edward Cree approach:
https://patchwork.ozlabs.org/patch/877222/
Additional state pruning heuristics make such brute force loop walk
practical even for large loops.

The commit 7640ead93924 partially resolved the issue of callees
incorrectly pruning the callers.
With introduction of bounded loops and jmps_processed heuristic
single verifier state may contain multiple branches and calls.
It's possible that new verifier state (for future pruning) will be
allocated inside callee. Then callee will exit (still within the same
verifier state). It will go back to the caller and there R6-R9 registers
will be read and will trigger mark_reg_read. But the reg->live for all frames
but the top frame is not set to LIVE_NONE. Hence mark_reg_read will fail
to propagate liveness into parent and future walking will incorrectly
conclude that the states are equivalent because LIVE_READ is not set.
In other words the rule for parent/live should be:
whenever register parentage chain is set the reg->live should be set to LIVE_NONE.
is_state_visited logic already follows this rule for spilled registers.

Fixes: 7640ead93924 ("bpf: verifier: make sure callees don't prune with caller differences")
Fixes: f4d7e40a5b71 ("bpf: introduce function calls (verification)")

Add a bunch of loop tests. Most of them are created by replacing
'#pragma unroll' with '#pragma clang loop unroll(disable)'

Several tests are artificially large:
  /* partial unroll. llvm will unroll loop ~150 times.
   * C loop count -> 600.
   * Asm loop count -> 4.
   * 16k insns in loop body.
   * Total of 5 such loops. Total program size ~82k insns.
   */
  "./pyperf600.o",

  /* no unroll at all.
   * C loop count -> 600.
   * ASM loop count -> 600.
   * ~110 insns in loop body.
   * Total of 5 such loops. Total program size ~1500 insns.
   */
  "./pyperf600_nounroll.o",

  /* partial unroll. 19k insn in a loop.
   * Total program size 20.8k insn.
   * ~350k processed_insns
   */
  "./strobemeta.o",

Introduce precision tracking logic that

bpf_lxc_jit.o        39389    50925        39389      50925

Consider code:
654: (85) call bpf_get_hash_recalc#34
655: (bf) r7 = r0
656: (15) if r8 == 0x0 goto pc+29
657: (bf) r2 = r10
658: (07) r2 += -48
659: (18) r1 = 0xffff8881e41e1b00
661: (85) call bpf_map_lookup_elem#1
662: (15) if r0 == 0x0 goto pc+23
663: (69) r1 = *(u16 *)(r0 +0)
664: (15) if r1 == 0x0 goto pc+21
665: (bf) r8 = r7
666: (57) r8 &= 65535
667: (bf) r2 = r8
668: (3f) r2 /= r1
669: (2f) r2 *= r1
670: (bf) r1 = r8
671: (1f) r1 -= r2
672: (57) r1 &= 255
673: (25) if r1 > 0x1e goto pc+12
 R0=map_value(id=0,off=0,ks=20,vs=64,imm=0) R1_w=inv(id=0,umax_value=30,var_off=(0x0; 0x1f))
674: (67) r1 <<= 1
675: (0f) r0 += r1

At this point the verifier will notice that scalar R1 is used in map pointer adjustment.
R1 has to be precise for later operations on R0 to be validated properly.

The verifier will backtrack the above code in the following way:
last_idx 675 first_idx 664
regs=2 stack=0 before 675: (0f) r0 += r1         // started backtracking R1 regs=2 is a bitmask
regs=2 stack=0 before 674: (67) r1 <<= 1
regs=2 stack=0 before 673: (25) if r1 > 0x1e goto pc+12
regs=2 stack=0 before 672: (57) r1 &= 255
regs=2 stack=0 before 671: (1f) r1 -= r2         // now both R1 and R2 has to be precise -> regs=6 mask
regs=6 stack=0 before 670: (bf) r1 = r8          // after this insn R8 and R2 has to be precise
regs=104 stack=0 before 669: (2f) r2 *= r1       // after this one R8, R2, and R1

Two scalar registers not marked precise are equivalent from state pruning point of view.
More details in the patch comments.

It doesn't support bpf2bpf calls yet and enabled for root only.

+ * call foo // uses callee's r6 inside to compute r0
+ * r0 += r6
+ * if r0 == 0 goto
+ *
+ * to track above reg_mask/stack_mask needs to be independent for each frame.

Tests would be great, verifier complexity is at the level, where it's
very easy to miss issues.

Was fuzzying approach ever discussed for BPF verifier? I.e., have a
fuzzer to generate both legal and illegal random small programs. Then
re-implement verifier as user-level program with straightforward
recursive exhaustive verification (so no state pruning logic, no
precise/coarse, etc, just register/stack state tracking) of all
possible branches. If kernel verifier's verdict differs from
user-level verifier's verdict - flag that as a test case and figure
out why they differ. Obviously that would work well only for small
programs, but that should be a good first step already.

In addition, if this is done, that user-land verifier can be a HUGE
help to BPF application developers, as libbpf would (potentially) be
able to generate better error messages using it as well.

In theory that sounds good, but doesn't work in practice.
The kernel verifier keeps changing faster than user space can catch up.
It's also relying on loaded maps and all sorts of callbacks that
check context, allowed helpers, maps, combinations of them from all
over the kernel.
The last effort to build kernel verifier as-is into .o and link
with kmalloc/map wrappers in user space was here:
https://github.com/iovisor/bpf-fuzzer
It was fuzzing the verifier and was able to find few minor bugs.
But it quickly bit rotted.

Folks brought up in the past the idea to collect user space
verifiers from different kernels, so that user space tooling can
check whether particular program will load on a set of kernels
without need to run them in VMs.
Even if such feature existed today it won't really solve this production
headache, since all kernels prior to today will not be covered.

I think syzbot is still generating bpf programs. iirc it found
one bug in the past in the verifier core.
I think the only way to make verifier more robust is to keep
adding new test cases manually.
Most interesting bugs we found by humans.

Another approach to 'better error message' that was considered
in the past was to teach llvm to recognize things that verifier
will reject and let llvm warn on them.
But it's also not practical. We had llvm error on calls.
Then we added them to the verifier and had to change llvm.
If we had llvm error on loops, now we'd need to change it.
imo it's better to let llvm handle everything.

That all makes sense. Thanks for elaborate explanation!

We've been working (with Xiao Han, cc'ed) on an update of bpf-fuzzer.  It
helped us find a few issues in the verifier (mostly thanks to
warn_on("verifier bug")s).  I'll probably send a patchset to the main
repository in the next few weeks.

Updating the glue code (userspace wrappers) is okay so far, as long as
done regularly.

syzkaller's template description of BPF programs is very limited.  It
produces valid BPF instructions, but loaded programs make little sense,
are trivial or invalid, and don't go very far in the verifier.  We
probably can't rely on syzkaller to be effective for the verifier.

Tests and reviews are definitely the most effective ways to find bugs,
despite the above two fuzzers.  The verifier is complex enough that the
random approach of fuzzers has a hard time covering the code.

I know these are already in bpf-next sorry it took me awhile to get
time to review, but looks good to me. Thanks! We had something similar
in the earlier loop test branch from last year.

> Any idea what happened here? Going from 34439 -> 174607 on the new clang?

As I was alluding in commit log newer clang is smarter and generates
less spill/fill of constants.
In particular older clang loads two constants into r8 and r9
and immediately spills them into stack. Then fills later,
does a bunch of unrelated code and calls into helper that
has ARG_ANYTHING for that position. Then doing a bit more math
on filled constants, spills them again and so on.
Before this patch (that tracks spill/fill of constants into stack)
pruning points were equivalent, but with the patch it sees the difference
in registers and declares states not equivalent, though any constant
is fine from safety standpoint.
With new clang only r9 has this pattern of spill/fill.
New clang manages to keep constant in r8 to be around without spill/fill.
Existing verifier tracks constants so even without this patch
the same pathalogical behavior is observed.
The verifier need to walk a lot more instructions only because
r8 has different constants.

It's not in bpf-next yet :)
Code reviews are appreciated at any time.
Looks like we were just lucky with older clang.
I haven't tracked which clang version became smarter.
If you haven't seen this issue and haven't changed cilium C source
to workaround that then there is chance you'll hit it as well.
By "new clang" I meant version 9.0
"old clang" is unknown. I just had cilium elf .o around that
I kept using for testing without recompiling them.
Just by chance I recompiled them to see annotated verifier line info
messages with BTF and hit this interesting issue.
See patch 9 backtracking logic that resolves this 'precision of scalar'
issue for progs compiled with both new and old clangs.

FYI, we noticed the following commit (built with gcc-7):

commit: 9fe4f05d33eae0421a065e3bced38905b789c4e8 ("[PATCH v3 bpf-next 4/9] bpf: introduce bounded loops")
url: https://github.com/0day-ci/linux/commits/Alexei-Starovoitov/bpf-bounded-loops-and-other-features/20190617-041439
base: https://git.kernel.org/cgit/linux/kernel/git/bpf/bpf-next.git master

in testcase: kernel_selftests
with following parameters:

	group: kselftests-00

test-description: The kernel contains a set of "self tests" under the tools/testing/selftests/ directory. These are intended to be small unit tests to exercise individual code paths in the kernel.
test-url: https://www.kernel.org/doc/Documentation/kselftest.txt


on test machine: qemu-system-x86_64 -enable-kvm -cpu SandyBridge -smp 2 -m 4G
