I have a (reproducable) problem with directory access rights.
First I create a simple test squashfs:
mddir test
cd test
mkdir secure
echo "abc" >secure/abc.txt
chmod go-rwx secure
cd ..
mksquashfs test test.sfs
then I mount aufs with a ramisk-layer above the squashfs (mount-point /save):
losetup /dev/loop2 test.sfs
mkdir /mnt/mp1
mount -t tmpfs -o size=10000k tmpfs /mnt/mp1
mkdir /mnt/mp2
mount /dev/loop2 /mnt/mp2
mount -t aufs -o dirs=/mnt/mp1:/mnt/mp2 none /save
then I make the "secure"-directory accessable for everybody:
cd /save
chmod a+rx secure
then I try to act as an unprivileged user ("sam"):
su sam
ls -ld secure
drwxr-xr-x 2 root root 40 2008-02-07 00:35 secure
everything looks fine, but
ls secure/
returns "ls: cannot open directory secure/: Permission denied"
also
cd secure
returns "bash: cd: secure: Permission denied"
I downloaded the current "monday build" of aufs on January, 25th and am using
the new 2.6.24 kernel.
I would be happy with any clues how to get around this problem!
Greetings, Michael
