Centos 5.3 tar e rpm sempre dão defeito de segmentação - você pode dizer por que da strace?

Question

(Atualização: Hoje, o tar funciona sem segfault sem alterações conhecidas no sistema. O comando "rm" agora é segmentado. Argh! Talvez isso esteja sendo causado pelo ESXi? Ou talvez pelo hardware.)

Eu tenho um sistema Centos 5.3 em execução no VMWare ESXi. Tem funcionado por um bom tempo sem muito problema. Recentemente, no entanto, notei que o comando tar e o comando rpm me da uma falha de segmentação quando eu os executo.

Então, eu tentei usar strace (alguém achou isso sugerido online) e abaixo está o que eu recebo quando uso strace. Gostaria de saber como consertar meu sistema e como posso evitar que isso aconteça no futuro.

Obrigado antecipadamente!

Answer 1

Ok, não tão complexo quanto eu pensava. O servidor foi comprometido e o gênio hacker estragou a instalação do kit raiz. Então, o efeito foi binarios segfaulting. Outro efeito foi o tráfego de rede inesperado do servidor. Obrigado a todos que responderam!

    

Answer 2

Mesmo sem muita investigação, a partir da sua descrição de que alguns programas começaram a se fragmentar, eles começaram a funcionar corretamente enquanto outros começaram a falhar, você tem módulos de memória defeituosos ou uma pré-conexão quebrada.

Primeiro, pare todas as suas máquinas virtuais, reinicialize o host e execute um teste de memória. Você tem que fazer isso do lado de fora do ESXi. Se você encontrar algum defeito de memória, esse é o seu problema. Substitua o hardware.

Se nenhum defeito de memória foi encontrado, verifique se você está executando o último kernel disponível do CentOS para sua arquitetura.

Inicialize o host e o servidor novamente, o servidor no modo de usuário único (passe "single" para os parâmetros do kernel) e execute:

prelink -avf

Quando o prelink terminar, você deverá reinicializar o servidor. Você também pode fazer telinit u && init 3 para reiniciar a inicialização, mas é melhor reinicializar para assegurar que todos os binários serão recarregados com seus novos mapeamentos de memória.

    

Answer 3

Isso é um palpite, mas tente desligar o SE-linix e ver se funciona.

Ele não deve ser segmentado, mas pode haver um arquivo que não pode ser aberto por causa do se-linux que o tar nunca pensou que aconteceria.

Se você tiver que instalar o rpm de origem para o tar, e compilá-lo com a depuração, execute-o no depurador para ver o motivo.

    

Answer 4

Tudo bem, parece muito divertido.

Primeiro, você tem duas caixas idênticas e atualizadas (uma das quais não é segmentada)?

Se sim, verifique o md5sum nos binários que estão em segfault, certifique-se de que eles sejam iguais.

Em seguida, execute o ldd nos binários que estão falhando e, em seguida, execute o md5sum nas bibliotecas para ver se eles são diferentes.

Agora, supondo que as bibliotecas sejam as mesmas, algo está errado, provavelmente ambiente de máquina ou configuração, mas vamos ver se a strace lança alguma luz.

Para citar sua strace, perto do fim, você tem:

 open("/proc/mounts", O_RDONLY|O_LARGEFILE) = 3
 fstat64(3, {st_mode=S_IFREG|0444, st_size=0, ...}) = 0
 mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb7f85000
 read(3, "rootfs / rootfs rw 0 0\n/dev/root"..., 4096) = 587
 read(3, "", 4096)                       = 0
 close(3)                                = 0
 munmap(0xb7f85000, 4096)                = 0

A próxima linha é a mensagem de segfault.

Na minha máquina CentOS 5.3 (rpm versão 4.4.2.3), meu rpm faz isso imediatamente:

open("/usr/lib/locale/locale-archive", O_RDONLY) = 3
fstat(3, {st_mode=S_IFREG|0644, st_size=56458752, ...}) = 0
mmap(NULL, 56458752, PROT_READ, MAP_PRIVATE, 3, 0) = 0x2b36f9d01000
close(3)                                = 0

Eu arriscaria, assim, que o problema seja fechar a memória depois de ler / proc / mounts ou abrir / usr / lib / locale / locale-archive. Como o munmap () retornava 0, eu dava latido na árvore de localidade.

Por acaso, se sua configuração excluir a localidade, o próximo bloco que a minha executa é:

 open("/usr/lib/rpm/rpmpopt-4.4.2.3", O_RDONLY) = 3
 lseek(3, 0, SEEK_END)                   = 23100
 lseek(3, 0, SEEK_SET)                   = 0
 read(3, "#/*! \page config_rpmpopt Defaul"..., 23100) = 23100
 close(3)        

Boa sorte e deixe-nos saber o que você encontra.
