Description

The cd9660_open() does pass whole path to dirmatch() and we need to compare only the current path component, not full path. The 10412 did compare the full path.

Additinally, skip over duplicate / (if any) and check if the last component in the path was meant to be directory (having trailing /). If it is in fact a file, error out.

Testing done: used ls with different path names, with and without trailing /, different directory levels.

I have iso image:
disk3: BIOS drive F (41943040 X 512):
disk3: ISO9660

and it’s root is:
ok ls disk3:
disk3:/
.catalog
d .cdrom
.image_info
.livecd-cdrom-content
.volsetid
bin
d boot
d dev
d devices
d export
d home
d jack
d mnt
d platform
d proc
reconfigure
d root
d save
solaris.zlib
solarismisc.zlib
d system
d tmp

ok ls disk3:reconfigure/
open 'disk3:reconfigure/' failed: not a directory
ok ls disk3:reconfigure
disk3:reconfigure
ok ls disk3:boot
disk3:boot
d acpi
cdboot
.. and so on

ok ls disk3:boot/forth
disk3:boot/forth
beadm.4th
beastie.4th
brand.4th
…

ok ls disk3:boot/forth/beadm.4th/
open 'disk3:boot/forth/beadm.4th/' failed: not a directory

Also confirmed by Peter.
