A integração com **DG Library** para slicing estático é crítica. + +2. **Falsos negativos por falta de orquestração** — Teste 5 mostra que o KLEE detecta o erro mas o pipeline não o propaga. O **Coordenador Central** com feedback loop entre motores é necessário. + +3. **Obsolescência da infraestrutura** — GoogleTest, BenchExec e Ubuntu precisaram de correções para funcionar em ambientes modernos. A migração para **LLVM 16, Ubuntu 22.04, C++17** é urgente. + +O baseline está estabelecido.

In the New Pass Manager (LLVM 16), `opt` **skips** +any `FunctionPass` on functions with `optnone` unless the pass declares +`isRequired() = true`. This was NOT the behavior in the Legacy PM (LLVM 6), +where passes were always run regardless of `optnone`. + +**Impact:** ALL 9 instrumentation passes were silently skipped: +- `NonDetPass` — no nondet function replacement +- `TargetPass` — no target function instrumentation +- `Map2CheckLibrary` — no `main` → `__map2check_main__` rename +- `MemoryTrackPass`, `OverflowPass`, `AssertPass`, etc. + +This caused `llvm-link` to fail with `symbol multiply defined: main` because +`NonDetGeneratorKlee.bc` defines its own `main()` (trampoline to +`__map2check_main__()`), but the original `main` was never renamed. + +**Fix:** Added `static bool isRequired() { return true; }` to all 9 passes. + +**Why tests didn't catch it:** The pass plugin load tests use +`opt -load-pass-plugin -passes=...` which verifies the pass *registers* +correctly, but with an empty input module. The unit tests test the C library +functions, not the LLVM passes. There were no integration tests that exercise +the full compile → instrument → link → execute pipeline. + +--- + +### Bug 3: Target function name not propagated (commit `0deb84e01`) + +**Symptom:** `Running TargetPass with: __VERIFIER_error` (instead of `reach_error`) + +**Root Cause:** During the New PM migration, the `callPass()` function was +modified to pass the target function name via an environment variable +(`MAP2CHECK_TARGET_FUNCTION`). However, the `TargetPass` reads the function +name from a `cl::opt` flag (`-function-name`), not from an environment +variable.

INTRODUÇÃO +A massiva integração de software em sistemas críticos, abrangendo desde o gerenciamento de dispositivos médicos e o controle automotivo até complexas redes de distribuição de energia, impõe requisitos de confiabilidade e segurança que são absolutamente rigorosos. Em tais infraestruturas, uma falha de software pode ter consequências catastróficas, resultando em perdas financeiras significativas ou, em cenários mais graves, na perda de vidas. Em sistemas embarcados, que constituem a base tecnológica fundamental dessas aplicações, a **verificação formal** é vital. Como salientam Rocha et al. (2020), ela transcende a mera detecção de bugs, permitindo provar matematicamente a correção de um programa em relação à sua especificação de comportamento. Esta necessidade crítica é ainda mais amplificada em ambientes com severa restrição de hardware, onde técnicas de otimização, como o fatiamento de código (*program slicing*), tornam-se essenciais para reduzir o *footprint* de memória necessário para o processo de verificação (CHALUPA et al., 2021). + +Embora o Map2Check seja um verificador consolidado para programas em C, utilizando com sucesso uma abordagem híbrida de análise estática e dinâmica (ROCHA et al., 2020), o panorama competitivo atual é impulsionado por ferramentas de orquestração avançada que definem o verdadeiro estado da arte. Soluções de ponta, como o FuSeBMC, demonstraram uma capacidade superior de encontrar falhas, utilizando a injeção estratégica de *smart seeds* para alcançar taxas de sucesso superiores a 81% em categorias críticas da SV-COMP (ALSHMRANY et al., 2024). Da mesma forma, o Symbiotic se destaca pela integração profunda de *slicing* estático com a execução simbólica do KLEE (CHALUPA et al., 2021), superando a performance e a eficiência atuais do Map2Check ao reduzir drasticamente o espaço de busca. A ausência de mecanismos dinâmicos de realimentação e de um passo de *slicing* agressivo coloca a versão atual do Map2Check em desvantagem técnica. + +A arquitetura legada da ferramenta brasileira, que opera sobre plataformas mais antigas como LLVM 6.0 e KLEE 2.0, gerou desafios de escalabilidade e uma crescente obsolescência tecnológica. Essa dependência cria um "teto de vidro" para o desempenho, manifestando-se em redundância de processamento, onde o motor simbólico analisa trechos de código irrelevantes, e uma baixa cobertura efetiva em códigos de alta complexidade (ROCHA et al., 2020). Essa ineficiência se traduz diretamente em *timeouts* e vereditos inconclusivos (*unknown*) nas competições. Para mitigar esses *timeouts* e aumentar significativamente a precisão em sistemas com manipulação complexa de memória e ponteiros, propõe-se uma otimização fundamental: a utilização da biblioteca DG (*Dependence Graph*) para o cálculo da densidade de dependências antes da transferência simbólica. Essa nova fase de pré-processamento permitirá que o Map2Check 2.0 não apenas fatie o código, mas também priorize as entradas mais promissoras: + +* **Cálculo da Densidade no SDG:** O módulo Coordenador realizará uma análise do grafo de dependência do sistema (SDG) para identificar sementes cujos caminhos percorridos possuam o maior número de arestas conectadas diretamente ao critério de fatiamento (como instruções de erro ou acessos críticos a ponteiros). +* **Transferência Seletiva (Smart Seeds):** Apenas as *Smart Seeds* que demonstrarem uma "alta densidade" — ou seja, o maior potencial de influenciar o estado de erro devido à sua alta conectividade a pontos críticos do programa — serão enviadas ao KLEE para a tentativa de *branch flipping* e resolução de guardas lógicas complexas. +* **Otimização de Memória e Tempo:** Ao focar a análise simbólica exclusivamente em caminhos com dependências críticas de dados e controle, a ferramenta evita o processamento de grandes trechos de código irrelevantes (código morto ou puramente computacional), o que é decisivo para mitigar os *timeouts* em *benchmarks* industriais. + +Esta abordagem integrada é particularmente vantajosa e estratégica para a Linha de Pesquisa em Sistemas Embarcados e Distribuídos, pois: + +1. **Restrição de Recursos:** O *slicing* reduz drasticamente o *footprint* de memória necessário para a verificação, o que é um requisito essencial para a análise de *firmware* embarcado. +2. **Complexidade de Dados:** A priorização baseada no SDG lida de forma superior com a complexa manipulação de ponteiros e estruturas de dados dinâmicas, que são extremamente comuns em sistemas de controle. +3. **Verificação de Witness:** A integração com o BenchExec e a validação interna garantem que as falhas detectadas em sistemas distribuídos sejam reprodutíveis através de casos de teste concretos, um passo crucial para eliminar falsos positivos e garantir a credibilidade científica dos resultados. + +**1.1 Problema de Pesquisa** + +O problema central a ser abordado é a ineficiência arquitetural que resulta em uma alta taxa de vereditos inconclusivos (*unknown*) e *timeouts* no Map2Check. Dados indicam que em categorias desafiadoras como *ReachSafety* e *MemSafety*, a ferramenta falha em convergir dentro dos limites de tempo. Por exemplo, em avaliações comparativas, ferramentas concorrentes que utilizam orquestração avançada de sementes (*smart seeds*), como o FuSeBMC, alcançam taxas de sucesso superiores a 81% em categorias onde o Map2Check apresenta desempenho inferior ou estouro de recursos (ALSHMRANY et al., 2024; BEYER, 2023). A questão norteadora é: **Como a implementação de uma heurística de priorização de sementes baseada em densidade de dependências (SDG), pode otimizar a transferência de *Smart Seeds* entre o AFL++ e o KLEE para maximizar a cobertura de erros em códigos com alta complexidade de memória?** +--- + +2\. FUNDAMENTAÇÃO TEÓRICA +A verificação de software híbrida combina o rigor da análise formal com a velocidade dos testes dinâmicos. Esta seção detalha os pilares teóricos que sustentam a proposta. + +2.1 Execução Simbólica e KLEE +A execução simbólica é uma técnica que analisa programas assumindo valores simbólicos para as entradas, em vez de valores concretos. Durante a execução, o motor constrói um conjunto de restrições lógicas (path constraints) que representam as condições necessárias para percorrer cada caminho do programa. Solucionadores SMT (Satisfiability Modulo Theories), como o Z3, são utilizados para verificar a satisfatibilidade desses caminhos e gerar contraexemplos em caso de erro (CADAR et al., 2008). + +O KLEE é o motor de execução simbólica de referência para bitcode LLVM. Embora poderoso, o KLEE sofre do problema de "explosão de caminhos" (path explosion), onde o número de caminhos a explorar cresce exponencialmente com o tamanho do programa e a presença de laços (loops), tornando a análise exaustiva inviável para softwares grandes (CADAR et al., 2008). A versão utilizada atualmente pelo Map2Check (v2.0) carece de heurísticas recentes de fusão de estados (state merging) e otimizações de query caching presentes nas versões mais novas (v3.1+) (KLEE TEAM, 2024). + +2.2 Fuzzing Guiado por Cobertura (Greybox Fuzzing) +O fuzzing é uma técnica de teste de software que envolve a injeção de dados aleatórios ou mutados nas entradas de um programa para provocar falhas (crashes). O fuzzing moderno, exemplificado pelo AFL (American Fuzzy Lop) e seu sucessor AFL++, utiliza instrumentação em tempo de compilação para monitorar a cobertura de arestas do grafo de fluxo de controle (CFG). Se uma entrada aleatória descobre um novo caminho no código, ela é salva como uma "semente" (seed) para mutações futuras (FIORALDI et al., 2020). +Diferentemente da execução simbólica, o fuzzing é extremamente rápido e eficaz em encontrar bugs superficiais, mas tem dificuldade em penetrar em caminhos protegidos por condições complexas (ex: if (x \== 0xDEADBEEF)), conhecidas como "números mágicos" (FIORALDI et al., 2020). + +2.3 Infraestrutura LLVM e Pass Manager +O LLVM é um conjunto de tecnologias modulares de compiladores. Sua peça central é a Representação Intermediária (LLVM IR), uma linguagem assembly tipada independente de arquitetura. A análise e transformação de código no LLVM ocorrem através de "Passes". Até a versão 12, o LLVM utilizava o Legacy Pass Manager. A partir da versão 13, e consolidado na 15, o New Pass Manager tornou-se o padrão, introduzindo uma nova API C++ que oferece melhor granularidade de análise e paralelismo, mas que quebra a compatibilidade com passes antigos, exigindo a reescrita de ferramentas como o Map2Check (LLVM PROJECT, 2024; MENEZES et al., 2018). + +2.4 Program Slicing (Fatiamento de Programa) +O Program Slicing é uma técnica de redução de código que, dado um critério de fatiamento (ex: uma linha de código específica ou uma instrução de erro), remove todas as partes do programa que não influenciam esse critério, direta ou indiretamente. O uso de slicing estático, implementado através de bibliotecas como a DG (Dependence Graph), é fundamental para reduzir o espaço de busca antes da execução simbólica, eliminando computações irrelevantes que consumiriam recursos do solver SMT (CHALUPA et al., 2021). +--- + +3\. TRABALHOS RELACIONADOS +A análise do estado da arte revela que as ferramentas mais bem-sucedidas nas competições recentes abandonaram a execução monolítica em favor de arquiteturas de orquestração complexas. + +3.1 FuSeBMC (Alshmrany et al., 2022\) +O FuSeBMC v4 introduziu uma arquitetura inovadora baseada em um "Coordenador" e injeção de objetivos (Smart Seeds). A ferramenta utiliza um motor de Bounded Model Checking (BMC), o ESBMC, para resolver guardas lógicas complexas que bloqueiam o fuzzer. As entradas geradas pelo BMC são convertidas em sementes e injetadas no motor de fuzzing (AFL++), permitindo que este continue a exploração a partir de profundidades que não alcançaria sozinho. Esta estratégia de cooperação permitiu ao FuSeBMC superar ferramentas tradicionais na Test-Comp, atingindo altas taxas de cobertura (ALSHMRANY et al., 2024). O Map2Check atual carece dessa realimentação dinâmica; seus motores operam em fases distintas, sem compartilhar o aprendizado em tempo real. + +3.2 Symbiotic (Chalupa et al., 2021\) +O Symbiotic destaca-se na categoria MemSafety da SV-COMP. Sua principal contribuição é a integração profunda de slicing estático com a execução simbólica do KLEE. Antes de qualquer verificação, o Symbiotic utiliza a biblioteca DG para construir um grafo de dependência e remover trechos de código que não afetam as instruções de segurança monitoradas. Isso reduz drasticamente o tamanho do bitcode e a complexidade das fórmulas SMT (CHALUPA et al., 2021). A ausência de um passo de slicing agressivo no Map2Check é identificada como uma das causas primárias de seus timeouts. + +3.3 VeriAbs (Afzal et al., 2019\) +O VeriAbs utiliza uma abordagem de portfólio baseada na estrutura de laços. Ele analisa estaticamente os loops do programa e seleciona a estratégia de verificação mais adequada (ex: indução matemática para laços infinitos ou desenrolamento limitado para laços finitos). Embora o Map2Check tente lidar com laços, sua estratégia é estática e muitas vezes resulta em explosão de caminhos, diferentemente da adaptação dinâmica do VeriAbs (AFZAL et al., 2019). +--- + +4\. MÉTODO + +A reestruturação do Map2Check será guiada pela modernização do motor de orquestração e a integração de análise de dependências para redução do espaço de estados. A Figura 1 ilustra a arquitetura proposta, onde o componente "Coordenador" centraliza o gerenciamento do ciclo de vida da verificação. + +![][image1] +Figura 1: Arquitetura proposta para o Map2Check modernizado, destacando o fluxo de sementes inteligentes. + +​O desenvolvimento metodológico está estruturado nos seguintes eixos: +​4.1 Eixo 1: Modernização da Infraestrutura +Começaremos com a ​migração para LLVM 15+ e C++17, adaptando as classes de instrumentação para o New Pass Manager (PassInfoMixin) para garantir compatibilidade com pipelines de otimização modernas. +Embora versões mais recentes do LLVM (como 18 ou 19\) estejam disponíveis, a escolha da versão 15 é estratégica para garantir a estabilidade das dependências críticas. O motor simbólico KLEE 3.1 possui suporte oficial robusto até o LLVM 15, e a biblioteca DG (utilizada para o slicing) frequentemente apresenta atrasos na adaptação para as mudanças frequentes na API do LLVM (breaking changes). A versão 15 oferece o equilíbrio ideal entre acesso a recursos modernos (como Opaque Pointers) e a confiabilidade necessária para ferramentas de verificação formal (KLEE TEAM, 2024; CHALUPA et al., 2021). +Por causa disso as classes que herdam de ModulePass (legado) precisarão ser reescritas para o novo modelo de gerenciamento de passes, permitindo que a instrumentação de segurança do Map2Check seja intercalada com passes de otimização O3 padrão, melhorando a qualidade do código analisado. + +​4.2 Eixo 2: Arquitetura de Hibridização Dinâmica +​Desenvolvimento de um Coordenador central para gerenciar a troca de sementes via IPC POSIX. O KLEE atuará como um solver de guardas lógicas, injetando Smart Seeds no AFL++ para superar bloqueios de cobertura. O Coordenador implementará uma heurística de "Desbloqueio de Fronteira". Uma semente no AFL++ será considerada "promissora" e elegível para transferência ao KLEE quando: + +- Saturação Local: O AFL++ não descobre novos caminhos por um período de tempo Δ t (estagnação da cobertura). +- ​Proximidade de Fronteira: A semente executa um caminho que atinge uma instrução de desvio (branch) onde uma das arestas nunca foi tomada (cobertura 0). + +O Coordenador suspende o AFL++, extrai essa semente e a invoca no KLEE com o objetivo explícito de negar a condição do desvio (branch flipping). Se o KLEE resolver a restrição, a nova entrada (Smart Seed) é injetada de volta na fila do AFL++, permitindo que o fuzzer avance para o novo bloco de código desbloqueado (ALSHMRANY et al., 2024). + +​4.3 Eixo 3: Otimização via Program Slicing (DG) +​Integração da biblioteca DG para realizar a redução estática do programa antes da análise dinâmica. + +* ​Critério de Slicing: O critério será definido automaticamente como o conjunto de todas as chamadas para a função \_\_VERIFIER\_error() e instruções de acesso à memória (para propriedades de MemSafety). Instruções que não afetam esses pontos (computações mortas para o propósito da verificação) serão removidas, reduzindo o tamanho do bitcode e aliviando a carga sobre o solver SMT. + +​4.4 Eixo 4: Validação e Padronização + +* ​Integração com BenchExec: Desenvolvimento de um módulo Python para gerenciar recursos (cgroups) e garantir a reprodutibilidade dos experimentos, alinhado aos padrões da SV-COMP. +* ​Validação de Testemunhos: Implementação de um passo de re-execução concreta, onde o contraexemplo gerado é testado contra o binário original compilado com GCC para confirmar a falha e eliminar falsos positivos. + +--- + +5\. RESULTADOS ESPERADOS +Com a implementação deste plano de modernização, espera-se alcançar os seguintes resultados quantitativos e qualitativos: + +1. Redução da Taxa de "Unknown": Espera-se reduzir a taxa de resultados inconclusivos de \~81% (observada em categorias difíceis) para menos de 30%, graças à eliminação de código morto pelo slicing e à maior robustez do KLEE atualizado. +2. Aumento da Cobertura de Código: A hibridização com AFL++ e Smart Seeds deve aumentar a cobertura de ramos (branch coverage) em benchmarks da Test-Comp em pelo menos 20% comparado à versão anterior, especialmente em programas com validações de entrada complexas. +3. Melhoria na Pontuação da SV-COMP: Projeta-se que o Map2Check modernizado alcance uma pontuação competitiva nas categorias ReachSafety e MemSafety, aproximando-se dos líderes atuais como VeriAbs e Symbiotic. +4. Disponibilidade e Portabilidade: A disponibilização de uma imagem Docker contendo todo o toolchain (LLVM 15, KLEE 3.1, AFL++, Z3) eliminará barreiras de instalação e garantirá a reprodutibilidade dos resultados científicos. + +--- + +6\.
