ANBZ: torvalds#342 This reverts commit 074d356. The commit 565c32b ("bpf: track spill/fill of constants") is backported from upstream kernel-4.19.y stable branch to fix cve, but it suffer serious degradation in the number of states processed and corresponding verification time increase. Loading cilium's bpf_lxc.o would fail beacause insn_processed exceeded BPF_COMPLEXITY_LIMIT_INSNS due to such degradation. To fix this problem, follow-up optimization patch 074d356 ("bpf:precise scalar_value tracking") was introduced. However, subsequent bug-fix patches was forgotten, caused bpf verifier incorrectly prune states, and some bpf instructions was misjudged as dead code, so the kernel was eventually soft lockup due to bpf verifier's dead-code overwritten. There are 3 ways to fix dead-code misjudgment problem: 1. backport follow-up bug-fix patches. 2. increase the number of BPF_COMPLEXITY_LIMIT_INSNS. 3. revert the cve-fix patches The first ways is more elegant, but is more risky. The bug-fix patches are: - a3ce685 ("bpf: fix precision tracking") - b3b50f0 ("bpf: fix precision bit propagation for BPF_ST instructions") - 6754172 ("bpf: fix precision tracking in presence of bpf2bpf calls") - 2339cd6 ("bpf: fix precision tracking of stack slots") - f54c789 ("bpf: Fix precision tracking for unbounded scalars") To make these patches work, one more seems irrelevant patch need to be backported too: 9242b5f ("bpf: add self-check logic to liveness analysis"). These patches modified too much code, and it is hard to ensure they won't introduce other bugs, so it is a risky solution. The second way could mitigate such degradation a little. Processing cilium bpf_lxc.o with 2900+ instructions, the statistics data is: cve-not-fixed cve-fixed fixed-with-optimization processed-insns 39024 293776 212987 verify-time 150+ms 3.6s 2.5s So the most practical solution is third way.

ANBZ: torvalds#342 commit c04c0d2 upstream Large verifier speed improvements allow to increase verifier complexity limit. Now regardless of the program composition and its size it takes little time for the verifier to hit insn_processed limit. On typical x86 machine non-debug kernel processes 1M instructions in 1/10 of a second. (before these speed improvements specially crafted programs could be hitting multi-second verification times) Full kasan kernel with debug takes ~1 second for the same 1M insns. Hence bump the BPF_COMPLEXITY_LIMIT_INSNS limit to 1M. Also increase the number of instructions per program from 4k to internal BPF_COMPLEXITY_LIMIT_INSNS limit. 4k limit was confusing to users, since small programs with hundreds of insns could be hitting BPF_COMPLEXITY_LIMIT_INSNS limit. Sometimes adding more insns and bpf_trace_printk debug statements would make the verifier accept the program while removing code would make the verifier reject it. Some user space application started to add #define MAX_FOO to their programs and do: MAX_FOO=100; again: compile with MAX_FOO; try to load; if (fails_to_load) { reduce MAX_FOO; goto again; } to be able to fit maximum amount of processing into single program. Other users artificially split their single program into a set of programs and use all 32 iterations of tail_calls to increase compute limits. And the most advanced folks used unlimited tc-bpf filter list to execute many bpf programs. Essentially the users managed to workaround 4k insn limit. This patch removes the limit for root programs from uapi. BPF_COMPLEXITY_LIMIT_INSNS is the kernel internal limit and success to load the program no longer depends on program size, but on 'smartness' of the verifier only. The verifier will continue to get smarter with every kernel release.
