In one of the Fedora CVS server setup, it says that if the
administrator wants to use a simple pserver remote string
such as:

export CVSROOT=':pserver:<username>@<systemname>:/cvs'

Then one has to:

1) /etc/xinetd.d/cvs:
    server_args             = -f --allow-root=/cvs pserver
2) ln -s /var/cvs /cvs

But the problem here is that SELinux has no context for
the symbolic link /cvs, therefore deny's access.

I tried setting context for /cvs by:
1) chcon -t cvs_data_t

No dice.  Does not work.

To see if I can cvs login bypassing Selinux, I tried:
1) setenforce 0
2) cvs login (successfully)
3) setenforce 1

So, what can I do to get SElinux to authorize the /cvs symbolic link access to /var/cvs?

Apologies to all.  It turns out that my email spam system was blocking me from
receiving email responses I was waiting for!  Geez, I will have to add another
TODO to my list.

To Paul: Can you explain what you mean by: "maybe try a bind mount instead of a symlink?"

I looked it up and understood a bind mount.  Answer is nope!

Bind mount:
========
mount --bind /var/cvs /cvs

ls -ldZ /cvs:
=======
drwxr-xr-x  cvs cvs system_u:object_r:cvs_t:s0       /cvs
So, the context is right, but still get a Permissions denied.

/sbin/ausearch -i -m AVC
================

Oh rats!  This error above was for something else!  My mistake!!!!

I had to trying logging in at the remote system but failed several times,
but after the 3rd try, I finally got in.  Not sure why the login process
stumbled.

So, It DOES work!


But I am having a problem with getting Eclipse's SVN to open a single file:

The server reported an error while performing the "cvs status" command.
  HelloWorld: cvs status: failed to create lock directory for `/cvs/Eclipse/C/Examples/HelloWorld' (/cvs/Eclipse/C/Examples/HelloWorld/#cvs.lock): Permission denied
  HelloWorld: cvs status: failed to obtain dir lock in repository `/cvs/Eclipse/C/Examples/HelloWorld'
  HelloWorld: cvs [status aborted]: read lock failed - giving up

Not sure why it is not able to lock this file for checkout/examination.  Any ideas?

To Stephen: "/sbin/ausearch -i -m AVC"
type=SYSCALL msg=audit(02/13/2008 19:17:32.484:5097) : arch=i386 syscall=open success=no exit=-13(Permission denied) a0=8faf660 a1=8000 a2=1b6 a3=8fafa58 items=0 ppid=25427 pid=27015 auid=dant uid=root gid=root euid=root suid=root fsuid=root egid=root sgid=root fsgid=root tty=(none) comm=cvs exe=/usr/bin/cvs subj=system_u:system_r:cvs_t:s0-s0:c0.c1023 key=(null)
