Re: svn: error while loading shared libraries: /usr/local/lib/libsvn_ra_dav-1.so.0: cannot restore segment port after reloc: Permission denied

Thanks but I don't quite understand why a firewall has anything to do  
with that error message.  If you simply type "svn", you are not  
accessing any remote servers.

The correct answer which I figured out after debugging is:

chcon -t texrel_shlib_t /usr/local/lib/libsvn_ra_dav-1.so

The SVN FAQ needs to be updated with this.  The FAQ does mention  
SELinux but only for the repository and not for any shared libraries.

<blockquote>
Note for SELinux / Fedora Core 3+ / Red Hat Enterprise users:

In addition to regular Unix permissions, under SELinux every file,  
directory, process, etc. has a 'security context'. When a process  
attempts to access a file, besides checking the Unix permissions the  
system also checks to see if the security context of the process is  
compatible with the security context of the file.

Fedora Core 3, among other systems, comes with SELinux installed by  
default, configured so that Apache runs in a fairly restricted  
security context. To run Subversion under Apache, you have to set the  
security context of the repository to allow Apache access (or turn  
off the restrictions on Apache, if you think all this is overkill).  
The chcon command is used to set the security context of files  
(similarly to how the chmod sets the traditional Unix permissions).  
For example, one user had to issue this command

    $ chcon -R -h -t httpd_sys_content_t PATH_TO_REPOSITORY

to set the security context to be able to successfully access the  
repository.
