Description Tim Burke 2009-01-07 14:11:08 UTC
Running RHEL5.3 circa about Dec 10.  Got this selinux issue.

Detailed DescriptionSELinux is preventing perl (logwatch_t) "write" to ./dmeventd_syslogpattern.txt (etc_t). The SELinux type etc_t, is a generic type for all files in the directory and very few processes (SELinux Domains) are allowed to write to this SELinux type. This type of denial usual indicates a mislabeled file. By default a file created in a directory has the gets the context of the parent directory, but SELinux policy has rules about the creation of directories, that say if a process running in one SELinux Domain (D1) creates a file in a directory with a particular SELinux File Context (F1) the file gets a different File Context (F2). The policy usually allows the SELinux Domain (D1) the ability to write, unlink, and append on (F2). But if for some reason a file (./dmeventd_syslogpattern.txt) was created with the wrong context, this domain will be denied. The usual solution to this problem is to reset the file context on the target file, restorecon -v './dmeventd_syslogpattern.txt'. If the file context does not change from etc_t, then this is probably a bug in policy.
