Esta é a saída de cat /proc/pid/maps , em que pid é o id do processo para o processo de pidgin. Aqui eu posso ver o intervalo de endereços de stack , heap . Mas o que é vdso e o que são outras linhas?

    

Answer 1

De acordo com a página de manual / proc , a saída de / proc / pid / maps será:

address           perms offset  dev   inode   pathname
08048000-08056000 r-xp 00000000 03:0c 64593   /usr/sbin/gpm

Onde:

• address é o espaço de endereço no processo que ocupa

• perms é um conjunto de permissões:

  r = leia
  w = escreva
  x = executar
  s = compartilhados p = privado (cópia ao escrever)
  

• offset é o deslocamento para o arquivo / qualquer que seja

• dev é o dispositivo (maior: menor)
• inode é o inode nesse dispositivo. 0 indica que nenhum inode está associado à região da memória, como seria o caso com o BSS (dados não inicializados).

• pathname se a região foi mapeada de um arquivo, esse é o nome do arquivo. Este campo está em branco para regiões mapeadas anônimas.

  No campo nome do caminho , pode haver outras coisas engraçadas:

  • [heap] é o endereço do heap do processo
  • [stack] é o endereço da pilha do processo
  • [vdso] significa objeto compartilhado dinâmico virtual. Ele é usado por chamadas do sistema para alternar para o modo kernel ( artigo detalhado sobre ele ).
