The fundamental problem stems from line 254 in util- linux-2.17.2/mount/umount.c where, when busy, it has this step:
remnt.mnt_type = remnt.mnt_fsname = NULL; Then it calls update_mtab(node, &remnt) 4 lines below this when nomtab is zero, leading to the null pointer manipulation that ultimately kills the process. My question is why are the mnt_type and mnt_fsname being cleared but not set to a sensible value? Neither are mnt_freq or mnt_passno for that matter, suggesting that using memset() to clear the remnt structure would be smarter, followed by assigning the sensible value to the type & name. -- umount segfault on shutdown when unmounting autofs mountpoint https://bugs.launchpad.net/bugs/579858 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
