Hi,
We are experiencing problems when testing file permissions on different
systems, AIX 3.2.5 and AIX 4.1.4 for instance.
It seems that after all in AFS3.4a the group and other modebits are
checked when testing the file permissions, but this does not happens in
AFS 3.3a.
Here is an example:
+AIX 3.2.5 and AFS 3.3a:
[noname]:admin> uname -srv
AIX 2 3
[noname]:admin> what /usr/vice/etc/afsd |grep Base
Base configuration afs3.3 1.59
[noname]:admin> ls -l
kshrc
-rwx------ 1 10850200 staff 8921 Jul 26 08:46 kshrc
[noname]:admin> [[ -x kshrc ]] && echo ok
ok
[noname]:admin> id
uid=106(jleon) gid=1(staff)
As you can see in this platform the group and other modebits are not
checked. This is a behavior I would expect.
+ AIX 4.1.4 and AFS 3.4a:
[rudy]:admin> uname -srv
AIX 1 4
[rudy]:admin> ls -l kshrc
-rwx------ 1 10850200 staff 8921 Jul 26 08:46 kshrc
[rudy]:admin> [[ -x kshrc ]] && echo ok
[rudy]:admin> id
uid=106(jleon) gid=1(staff)
[rudy]:admin> what /usr/vice/etc/afsd |grep Base
Base configuration afs3.4 4.36
But here, because the issuer is not the owner the file testing fails,
however if I change the mode bit as follows, it'll work:
[rudy]:admin> chmod g+x kshrc
[rudy]:admin> ls -l kshrc
-rwx--x--- 1 10850200 staff 8921 Jul 26 08:46 kshrc
[rudy]:admin> [[ -x kshrc ]] && echo ok
ok
This is what I don't understand... and it's becoming a big concern
because a lot of the scripts we have rely on file testing.
Have you seen or heard about this weird behavior ? Was there a change in
AFS that I am not aware of ?
Any information will be appreciated,
Thanks in advance,
Juan.
