When a simple map is used with nobind option, and
the destination is local, automount segfaults.
auto.master:
/t /etc/auto.t nobind
auto.t:
usr :/usr
With this map, accessing /t/usr makes automount to
crash. This is because modules/mount_nfs.c:mount_mount()
has this code:
this = hosts;
while (this) {
...
/* Port option specified, don't try to bind */
if (!(nosymlink || nobind) &&
!port_opt && this->proximity == PROXIMITY_LOCAL) {
...
/* No hostname, can't be NFS */
if (!this->name) {
this = this->next;
continue;
}
}
/* Not a local host - do an NFS mount */
if (this->rr && this->addr) {
...
} else {
loc = malloc(strlen(this->name) + strlen(this->path) + 2);
And here, it SIGSEGVs, since this->name is NULL.
I wonder if nobind EVER worked, since it is only meaningful
for a local mounts, and this is exactly the place where it
does not work.
