[Libguestfs] [PATCH] daemon: inspect: ignore fstab devs that cannot be resolved (RHBZ#1608131)

If the /etc/fstab of a guest contains devices specified with UUID or LABEL, then the new OCaml inspection code will report the findfs failure as general failure of the inspection. OTOH, the old C inspection code simply ignored all the devices that cannot be resolved. Hence, restore the old behaviour by ignoring unresolvable devices. --- daemon/inspect_fs_unix_fstab.ml | 12 ++++++++++-- 1 file changed, 10 insertions(+), 2 deletions(-) diff --git a/daemon/inspect_fs_unix_fstab.ml b/daemon/inspect_fs_unix_fstab.ml index edb797e3f..170440d2c 100644 --- a/daemon/inspect_fs_unix_fstab.ml +++ b/daemon/inspect_fs_unix_fstab.ml @@ -115,12 +115,20 @@ and check_fstab_entry md_map root_mountable os_type aug entry = if String.is_prefix spec "UUID=" then ( let uuid = String.sub spec 5 (String.length spec - 5) in let uuid = shell_unquote uuid in - Mountable.of_device (Findfs.findfs_uuid uuid) + (* Just ignore the device if the UUID cannot be resolved. *) + try + Mountable.of_device (Findfs.findfs_uuid uuid) + with + Failure _ -> return None ) else if String.is_prefix spec "LABEL=" then ( let label = String.sub spec 6 (String.length spec - 6) in let label = shell_unquote label in - Mountable.of_device (Findfs.findfs_label label) + (* Just ignore the device if the label cannot be resolved. *) + try + Mountable.of_device (Findfs.findfs_label label) + with + Failure _ -> return None ) (* Resolve /dev/root to the current device. * Do the same for the / partition of the *BSD -- 2.17.1
