Description Clyde E. Kunkel 2010-09-04 16:27:48 UTC

Summary:

SELinux is preventing plymouth "connectto" access on @/ply-boot-protocol.

Detailed Description:

[SELinux is in permissive mode. This access was not denied.]

SELinux denied access requested by plymouth. It is not expected that this access
is required by plymouth and this access may signal an intrusion attempt. It is
also possible that the specific version or configuration of the application is
causing it to require additional access.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug
report.

Comment 1 Nicolas Mailhot 2010-09-05 06:30:31 UTC

Résumé:

SELinux empêche l'accès en « connectto » à /bin/plymouth on @/ply-boot-prot

Description détaillée:

[SELinux est en mode permissif. Cet accès n'a pas été refusé.]

SELinux a refusé l'accès demandé par plymouth. Il n'est pas prévu que cet accès
soit requis par plymouth et cet accès peut signaler une tentative d'intrusion.
Il est également possible que cette version ou cette configuration spécifique de
l'application provoque cette demande d'accès supplémenta

Autoriser l'accès:

Vous pouvez créer un module de stratégie locale pour autoriser cet accès - lisez
la FAQ (http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Merci de
remplir un rapport de bogue.
