Description Lutz Lange 2008-10-02 04:47:35 EDT
Description of problem:
this man page states that you should do this:
If you want to make this permanant, i.e. survive a relabel, you must  add
       an entry to the file_contexts.local file.

              /var/ftp(/.*)? system_u:object_r:public_content_t  /var/ftp/incom-
              ing(/.*)? system_u:object_r:public_content_rw_t

There are two problems here.
1. this shows one line to put into file_contexts.local. This will result in an error, since it actually is two lines. 
Suggested Action: add a newline between ...:public_content_t /var/ft...

2. on rhel5 this does not actually do what you want, since the now first line allready exists and confilicts with an existing poklicy.
Suggested action: rewrite the man page to reflect this. Something like: add only the last line if your default policy includes a preset context for /var/ftp(/.*)? already.

Fixed in selinux-policy-2.4.6-164.el5
Comment 5 Lutz Lange 2008-10-17 05:24:20 EDT
Today i found out that you should indeed not edit  /etc/selinux/POLICYTYPE/contexts/files/file_contexts.local
manually since it is managed dynamically by libsemanage.

Instead i should use: 
semanage fcontext -a -t public_content_rw_t /var/ftp/incoming(/.*)?

If this is already in your fix, please disregard this comment.
Comment 6 Daniel Walsh 2008-10-17 08:43:34 EDT
That is what the man page says.
