[Clamav-devel] [SUSPECTED SPAM] [Feature request] Support Linux symlinks for all configuration and database folders

[Micah Snyder (micasnyd)]

Hello!

Apologies for the delay getting back to you.  I also saw this report: https://bugs.launchpad.net/ubuntu/+source/clamav/+bug/1920615/

I tried to reproduce the issue you described but was unable.  I tried moving the ssl directory and moving the clamav directory and then created symlinks to each. Eg:

root at 117df8bca60f:/# ls -la /var/lib/
total 64
...
lrwxrwxrwx 1 root   root     22 Mar 27 23:38 clamav -> /var/lib/clamav_moved/

and

root at 117df8bca60f:/# ls -la /etc/
...
lrwxrwxrwx 1 root root      15 Mar 27 23:37 ssl -> /etc/ssl_moved/

I had no problems running freshclam with these symlinks set up.  I don't think there is a bug here. I suspect that perhaps the permissions or ownership of your replacement directories or symlinks are causing the issue.  When freshclam is run by sudo, it switches users to run as the "clamav" user.  The database directory must be owned by the "clamav" user.  The config files, ssl files must be accessible to the clamav user.  

If you want to share your exact layout, ownership and permissions of these files and directories I can try to help more.
