Florian Weimer f4cba6ca1e dlfcn: Failures after dlmopen should not terminate process [BZ #15271] ... Commit 9e78f6f6e7 ("Implement _dl_catch_error, _dl_signal_error in libc.so [BZ #16628]") has the side effect that distinct namespaces, as created by dlmopen, now have separate implementations of the rtld exception mechanism. This means that the call to _dl_catch_error from libdl in a secondary namespace does not actually install an exception handler because the thread-local variable catch_hook in the libc.so copy in the secondary namespace is distinct from that of the base namepace. As a result, a dlsym/dlopen/... failure in a secondary namespace terminates the process with a dynamic linker error because it looks to the exception handler mechanism as if no handler has been installed. Backport notes: GLRO (dl_catch_error) is replaced with _dl_catch_error_ptr to preserve _rtld_global_ro layout. (cherry picked from commit b2964eb1d9)		2021-06-09 17:15:00 +02:00
