Subject: Strange SGID-Bit behavior with 2.2. and 2.4
Date: Thu, 20 Sep 2001 14:24:57 +0200 [thread overview]
Message-ID: <8414177426.20010920142457@teamix.net> (raw)
Hello almighty kernelgods...
a friend and I discovered some strange diffrence in the beahavior
of the 2.4, 2.2 Kernels.
Following Commands were done on both kernels:
---------------------------------------------
su -
cd /
mkdir test
chmod 2755 test
chown rdd test
su rdd
cd /test
touch a
chgrp users a
chmod 7777 a
cp a b
cp /bin/ls d
chgrp users d
chmod 7777 d
cp d e
These results are on 2.4.6
--------------------------
drwxr-sr-x 2 rdd root 190 Sep 14 15:17 .
drwxr-xr-x 22 root root 455 Sep 14 14:59 ..
-rwsrwsrwt 1 rdd users 0 Sep 14 15:00 a
-rwsr-sr-t 1 rdd root 0 Sep 14 15:02 b
-->^<-- What's that?
-rwsrwsrwt 1 rdd users 46568 Sep 14 15:07 d
-rwxr-xr-t 1 rdd root 46568 Sep 14 15:08 e
And these on 2.2.16
-------------------
drwxr-sr-x 2 rdd root 103 Sep 14 15:13 .
drwxr-xr-x 20 root root 369 Sep 14 15:10 ..
-rwsrwsrwt 1 rdd users 0 Sep 14 15:12 a
-rwsr-xr-t 1 rdd root 0 Sep 14 15:12 b
-rwsrwsrwt 1 rdd users 41552 Sep 14 15:12 d
-rwsr-xr-t 1 rdd root 41552 Sep 14 15:13 e
It happens both with ext2 and reiserfs.
Can anyone explain this behavior? Would be great.
If this is a damn stupid question, please drop it and kill me. :|
