Estou executando o mesmo binário de 32 bits, de terceiros e de código fechado desde 2018. Esta semana, em trixie/testingservidores Debian (possivelmente devido a uma libc6transição?), o programa começou a travar na inicialização. Infelizmente, não consigo fazer com que o fornecedor original o recompile para mim.
A única dica que tenho são estas linhas impressas no stdout:
Start of process LocalCtrl...
SL - error in dlopen(libDSS_Operator.so):
LocalCtrl initialization failed...
Ou preciso fazer isso funcionar ou preciso me comprometer a dar suporte ao Deb12 para sempre.
Qual é a melhor maneira de solucionar/consertar isso?
Posso reproduzir isso em um ambiente mais estéril com este programa de exemplo:
#include <stdio.h>
#include <dlfcn.h>
int main() {
void* so = dlopen(
"/opt/<package>/Cots/OPERATOR/libDSS_Operator.so",
RTLD_NOW
);
if (so == NULL) {
printf("dlopen() failed: %s\n", dlerror());
return 1;
}
printf("Success\n");
dlclose(so);
return 0;
}
Dei uma olhada em ldd, strace, LD_DEBUG=libs, e readelf.
Em uma máquina Deb11, onde o processo está funcionando bem, obtenho:

Reduzi um pouco a verbosidade patchelf --remove-rpathpara remover pesquisas desnecessárias, mas não houve nenhuma alteração em nenhuma das máquinas.
Esta é de fato uma mudança na glibc: na versão 2.41 , que migrou para o Debian 13 em 13 de março (substituindo a 2.40),
dlopennão permite mais que bibliotecas que exigem pilhas executáveis sejam carregadas se a pilha ainda não for executável:Isso aparece na sua saída:
Aparentemente, há uma ferramenta que pode limpar o sinalizador relevante , e o pacote Debian ainda está disponível em snapshots . Se a biblioteca não requer realmente uma pilha executável, mas parece apenas solicitar uma por omissão, então isso deve consertar as coisas.
