Bug 433241

Sommario
    SELinux ha impedito l'accesso a /var/log/wicd.log da parte di /sbin/ifconfig
    "write".

Descrizione dettagliata
    SELinux is preventing /sbin/ifconfig (ifconfig_t) "write" to
    /var/log/wicd.log (var_log_t). The SELinux type var_log_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 (/var/log/wicd.log) 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
    /var/log/wicd.log.  If the file context does not change from var_log_t, then
    this is probably a bug in policy.  Please file a
    http://bugzilla.redhat.com/bugzilla/enter_bug.cgi against the selinux-policy
    package. If it does change, you can try your application again to see if it
    works.  The file context could have been mislabeled by editing the file or
    moving the file from a different directory, if the file keeps getting
    mislabeled, check the init scripts to see if they are doing something to
    mislabel the file.

Abilitazione accesso in corso
    Potete cercare di correggere il contesto del file, eseguendo restorecon -v
    /var/log/wicd.log

    Il seguente comando abiliterà questo tipo d'accesso:
    restorecon /var/log/wicd.log
