SELinux has denied httpd access to potentially mislabeled file(s)
(./svn-new). This means that SELinux will not allow httpd to use these
files. It is common for users to edit files in their home directory or
tmp directories and then move (mv) them to system directories. The
problem is that the files end up with the wrong file context which
confined applications are not allowed to access. Allowing AccessIf you
want httpd to access this files, you need to relabel them using
restorecon -v './svn-new'. You might want to relabel the entire
directory using restorecon -R -v './svn-new'. Additional

This is on Fedora 9. In the past, I could have used
system-config-security and set selinux to allow web page serving from
user home directories but I don't see that tool any more.
What's the best way to handle this?
Easiest is just to fix the contexts of the files:
# semanage fcontext -a -t httpd_sys_content_t
# restorecon -rv /home/craig/svn-new
I'm not familiar with rails or how you maintain your svn checkout, so
httpd_sys_content_t may not be the appropriate type for all of the
content (are there any scripts in there, are you uploading content via
ftp, samba, etc.?). Since you're in permissive mode, it's not going to
cause you any problem other than possibly different warnings though.
If you maintain the checkout by manually doing an "svn update" from
your regular account, and the content isn't "executed" by httpd,
httpd_sys_content_t should be fine.
Thanks Paul...miss you on the Fedora-list
Thanks; when I had the first of my two children in September 2005 there
were a lot more demands on my time and some things I'd enjoyed devoting
a lot of my time to just had to go, and fedora-list was one of those.
I'm a bit confused myself because in essence, httpd is just a proxy to
the ruby/rails 'mongrel' which is a http server in ruby running the ruby
processes and is providing dhtml on higher ports as the user.
FWIW...httpd runs as user 'apache' (as ususal)
mongrels run as regular 'user' (me)
all files and folders inside the subdirectory we are discussing...
(/home/craig/svn-new) are owned by me (not root, not apache)
The conventional unix ownership and permissions make very little
difference as far as SELinux is concerned, so although you need to get
them right, they're not going to affect the file contexts needed.
What context is mongrels running in (try the -Z option of ps)? How does
that process get started (via an initscript?)?
I ran the commands that you suggested (ignoring the alerts raised by the
first command) and then restarted httpd service and got a new alert...

You probably need to run the ruby process confined so that it generates
files that are readable by httpd. It might actually work ok running as
httpd_t given how closely related the processes are.
