A tela GNU congela ao iniciar a sessão por SSH, funciona localmente. O que há de errado?

Em um iMac executando o Snow Leopard, posso abrir uma janela de terminal e iniciar uma sessão de 'tela' sem problemas. No entanto, se eu ssh na mesma máquina (de outro lugar ou localmente) e, em seguida, tentar iniciar uma sessão de 'tela', ele simplesmente trava. Nenhuma saída em tudo. Ele não responderá a Ctrl-d, Ctrl-c etc. e terá que ser eliminado através do PID. Uma sessão criada em um terminal local pode ser retomada a partir de uma sessão ssh. Isso ajuda a direcionar a suspeita para qualquer configuração?

Suspeito de um problema com um .bashrc, .profile etc., mas não sei o que se aplica nessa situação e não fiz alterações nessa área recentemente. Tudo isso é feito como o mesmo usuário.

Tenho 99% de certeza de que isso funcionou há pouco tempo, mas suponho que exista uma pequena possibilidade de que esse cenário não tenha aparecido antes para mim.

Em resposta às perguntas de Gilles abaixo:

As variáveis de ambiente são as mesmas nos dois casos. A maioria está em branco - apenas COLUMNS, LINES, HOME, PATH, SHELL e TERM foram definidos.

No estado suspenso, a tela não está recebendo nenhuma entrada. Quando é morto, o shell pai recebe qualquer entrada de teclado para a tela. Não consome tempo de CPU.

Assistindo aos dois processos de tela iniciados, o de menor número está fazendo o seguinte: 

$ sudo dtruss -p 1545
SYSCALL(args)        = return
sigreturn(0x7FFF5FBFEE80, 0x1E, 0x7FFF5FBFEE80)      = 0 Err#-2
__pthread_canceled(0x0, 0x0, 0x7FFF5FBFEF38)         = -1 Err#22
setitimer(0x0, 0x7FFF5FBFEF40, 0x7FFF5FBFEF20)       = 0 0
kill(0x60A, 0x0, 0x1)        = 0 0
sigaction(0xE, 0x7FFF5FBFEF10, 0x7FFF5FBFEF50)       = 0 0
setitimer(0x0, 0x7FFF5FBFEF40, 0x7FFF5FBFEF20)       = 0 0
sigprocmask(0x0, 0x0, 0x7FFF5FBFEF4C)        = 0x0 0
sigsuspend(0x0, 0x0, 0x0)        = -1 Err#4
<repeats approx every 10s>

O número mais alto só é gerado: 

$ sudo dtruss -p 1546
SYSCALL(args)        = return

A saída de 'dtruss -f -p $ pid_of_bash_that_starts_screen' com a duplicação removida é:

Você não é o único com esse problema. Tela trava em um pedaço de código específico da Apple. Parece que se você pegar esse código e recompilar, ele funciona .

  • Você precisa ter as ferramentas de desenvolvimento da Apple (Xcode) instaladas.

  • Faça o download da fonte de tela . (Há uma versão mais recente, a tela 19, onde você terá que remover o código incorreto manualmente em screen.c .) Em seguida, descompacte-o: 

    tar -xzf screen-16.tar.gz
cd screen-16

  • Retire o primeiro e o terceiro trecho do patch para screen.c ; ou seja, patches/screen.c.diff deve agora conter 

    --- screen.c    2003-09-08 07:26:41.000000000 -0700
+++ screen.c    2009-02-13 12:05:05.000000000 -0800
@@ -929,6 +934,16 @@
    Panic(0, "No $SCREENDIR with multi screens, please.");
 #endif
     }
+#ifdef __APPLE__
+    else if (!multi && real_uid == eff_uid) {
+      static char DarwinSockDir[PATH_MAX];
+      if (confstr(_CS_DARWIN_USER_TEMP_DIR, DarwinSockDir, sizeof(DarwinSockDir))) {
+   strlcat(DarwinSockDir, ".screen", sizeof(DarwinSockDir));
+   SockDir = DarwinSockDir;

+    }
+#endif /* __APPLE__ */
+
 #ifdef MULTIUSER
   if (multiattach)
     {

  • Agora compile o código: 

    make install_source
make

  • Verifique se o executável resultante /tmp/screen/Build/screen funciona.

  • Veja blog do D4T3N7OD para saber como substituir o executável da tela oficial pelo seu.

Não tenho ideia de por que a tela trava, por que a correção acima funciona e o que você perde removendo esse trecho de correção. Caso alguém esteja interessado, aqui está o quanto eu fui rastrear o código.

  • A tela bifurca um processo filho, que congela depois de abrir /dev/null em std {in, out, err} e chamando audit_session_self . O local correspondente na fonte está em screen.c , onde ver uma chamada para uma API da Apple privada: 

    #if defined(__APPLE__) && !TARGET_OS_EMBEDDED
    if (_vprocmgr_detach_from_console(0) != NULL)
        errx(1, "can't detach from console");
#endif

  • Este código parece ter origem no patch da Apple para tela 11 .

  • A implementação de _vprocmgr_detach_from_console parece estar em libvproc , onde leva a 

    task_name_for_pid(mach_task_self(), getpid(), &tnp);
vproc_mig_switch_to_session(bootstrap_port, tnp, (char *)target_session, _audit_session_self(), &new_bsport))

    Aqui reconhecemos _audit_session_self , a última chamada ao sistema (Darwin) que funcionou.

  • Em seguida, é a chamada Mach switch_to_session . É aí que eu perco a noção.

Isso está no macOS 10.12.6 (estava funcionando bem em 10.11.6 sem a mudança abaixo)

Se você estiver efetuando login via ssh e nohup estiver falhando na mesma chamada de sistema com erros ioctl e undefined e a tela estiver interrompida conforme descrito acima, ative UsePAM em / etc / ssh / sshd_config. Descobrimos que fazer um su-$ USER e, em seguida, executar a tela ou nohup funcionaria de dentro do SSH, mas o login direto via ssh e a execução dos comandos não (a menos que o UsePAM estivesse habilitado). Deve haver alguns recursos / ganchos de "segurança" que fazem com que isso seja ativado.
