TCL 8.x rootfs.gz files all owned by root:root

[MSumulong]

Somehow, all of the files in rootfs.gz of TCL 8.x are owned by root:root which I think should definitely not be the case.

@hiro has pointed this out earlier that I also discovered when using TCL 8.x's rootfs.gz.

after running "/usr/local/bin/cpio -i" on http://tinycorelinux.net/8.x/x86/release/distribution_files/rootfs.gz
many dirs are owned by root instead of staff.

There are a lot of directories that were once owned by root:staff (uid=0:gid=50) are now just root:root. Comparing the previous 7.x version of rootfs.gz shows that there are files that are owned by root:staff such as /opt:

Code: [Select]

drwxrwsr-x   2 0        50              0 Jul  4  2016 opt
-rw-rw-r--   1 0        50             31 Jul  4  2016 opt/tcemirror
-rwxrwxr-x   1 0        50             51 Jul  4  2016 opt/bootlocal.sh
-rw-rw-r--   1 0        50              9 Jul  4  2016 opt/.filetool.lst
-rwxrwxr-x   1 0        50            613 Jul  4  2016 opt/shutdown.sh
-rw-rw-r--   1 0        50            145 Jul  4  2016 opt/.xfiletool.lst
-rwxrwxr-x   1 0        50            272 Jul  4  2016 opt/bootsync.sh

Looking at /opt in TCL 8.x's rootfs.gz shows the files changed to gid=50:

Code: [Select]

drwxrwsr-x   2 0        0               0 Sep 21 12:16 opt
-rwxrwxr-x   1 0        0             272 Sep 21 12:16 opt/bootsync.sh
-rw-rw-r--   1 0        0             145 Sep 21 12:16 opt/.xfiletool.lst
-rwxrwxr-x   1 0        0             613 Sep 21 12:16 opt/shutdown.sh
-rw-rw-r--   1 0        0               9 Sep 21 12:16 opt/.filetool.lst
-rwxrwxr-x   1 0        0              51 Sep 21 12:16 opt/bootlocal.sh
-rw-rw-r--   1 0        0              31 Sep 21 12:16 opt/tcemirror
I've attached the full file listing of both TCL 8.x and 7.x's rootfs.gz.


rootfs.gz downloaded from the following links:
http://tinycorelinux.net/8.x/x86/release/distribution_files/rootfs.gz
http://tinycorelinux.net/7.x/x86/release/distribution_files/rootfs.gz

Used the following command to get the file listings:

Code: [Select]

gzip -dc rootfs.gz | cpio -tvn > cpio-listing


[polikuo]

Here's a quick script to find out the differences:
save this script as "chk_permissions"

Code: [Select]

#!/bin/sh
OLD=$1
NEW=$2
save_diff_as() {
ls -Ral | awk '{
if (/\->/)
print $1,$3,$4,($(NF-2))
else
print $1,$3,$4,$NF
}' > $1
}
cd $OLD || exit 1
save_diff_as /tmp/${OLD}.lst
cd - || exit 1
cd $NEW || exit 1
save_diff_as /tmp/${NEW}.lst
cd - || exit 1
diff -u /tmp/${OLD}.lst /tmp/${NEW}.lst | tee /tmp/ownership.diff

FYI
I extracted "rootfs-7.gz" to /tmp/7, "rootfs-8.gz" to /tmp/8
Run "chk_ownership /tmp/7 /tmp/8"

I'm away this week, I'll have a look as soon as I get back .

[Juanito]

How are you extracting the files from rootfs{,64}.gz?

Using Corepure64 8.2:

Code: [Select]

$ cd /tmp/extract
$ zcat /tmp/rootfs64.gz | sudo cpio -i -H newc -d
$ ls -l opt
total 16
-rwxrwxr-x    1 root     staff           51 Sep 28 21:11 bootlocal.sh
-rwxrwxr-x    1 root     staff          272 Sep 28 21:11 bootsync.sh
-rwxrwxr-x    1 root     staff          613 Sep 28 21:11 shutdown.sh
-rw-rw-r--    1 root     staff           31 Sep 28 21:11 tcemirror

..and:

Code: [Select]

$ ls -l

I wasn't extracting the files, I was just using cpio -tvn to get a file listing of what's inside the archive.

However, I was able to confirm getting the same results as you did with rootfs64.gz but not with rootfs.gz (the x86 version). Using Tiny Core Linux 8.2 x86 rootfs.gz and the same commands you used for Corepure 64 8.2, I get the following results:

OK, I see the same thing with rootfs.gz - this may have been due to a busybox cpio problem a while back.

I'll try to post a fixed version early next week.

[hiro]

Thanks Juanito, I had to remaster before use (enable serial console in inittab), so I wasn't sure if it's just my cpio usage or a borked release.

[Juanito]

Corrected rootfs.gz, etc posted.

[MSumulong]

Looks good, thanks Juanito!

[hiro]

I still get this from rootfs.gz
$ ls -la etc/sysconfig
total 4
drwxrwxr-x 2 root root  80 Oct  6 17:08 .
drwxr-xr-x 8 root root 660 Oct  6 17:08 ..
-rw-rw-r-- 1 root root   0 Oct  6 17:08 backup_device
-rw-r--r-- 1 root root  13 Oct  6 17:08 ntpserver

downloaded from http://tinycorelinux.net/8.x/x86/release/distribution_files/rootfs.gz

my steps were
gunzip rootfs.gz
mkdir root; cd root
sudo cpio -i < ../rootfs

[Juanito]

By comparison to rootfs64.gz, backup_device should be root:staff, but ntpserver should be root:root.

It looks like the correction of the folders under /etc was missed, I'll take a look.

[Juanito]

rootfs.gz reposted - hopefully I got them all this time...

[MSumulong]

Apologies, I may have spoken too soon. After looking into this in more detail, it looks like there are more files whose ownership needs to be changed in 8.2-x86 rootfs.gz:

Based on 7.x's rootfs.gz:

The following files are owned by root:staff

I checked the lists, and none of them need to be :staff; they just happened to be so before.
