From the backtrace of the core file, we can see that in function r00t(), after conf=THIS->private, conf == NULL, so it crashed when return conf->super_uid; the reason, i guess : iot_worker call_rerume GF_FOP_GETXATTR ,it wind to posix_acl_getxattr, in the meantime, fini() has been executed, so this->private = NULL and conf has been free. in this situation, i think we should check if conf is NULL before return conf->super_uid in r00t() Hi Ziyi, I have tried to reproduce after executed the test case on latest master release in centos VM for i in {1..10};do prove -vf tests/bugs/core/bug-1432542-mpx-restart-crash.t;done I am not able to reproduce it so I am closing the bug. Please reopen it if you are able to reproduce it on latest release. Thanks, Mohit Agrawal |
