The following was filed automatically by setroubleshoot: Résumé: SELinux is preventing modprobe "read write" access to to a leaked file descriptor on socket Description détaillée: [modprobe has a permissive type (insmod_t). This access was not denied.] SELinux denied access requested by the modprobe command. It looks like this is either a leaked descriptor or modprobe output was redirected to a file it is not allowed to access. Leaks usually can be ignored since SELinux is just closing the leak and reporting the error. The application does not use the descriptor, so it will run properly. If this is a redirection, you will not get output in the socket. You should generate a bugzilla on selinux-policy, and it will get routed to the appropriate package. You can safely ignore this avc. Autoriser l'accès: You can generate a local policy module to allow this access - see FAQ (http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Informations complémentaires: Contexte source unconfined_u:system_r:insmod_t:s0 Contexte cible unconfined_u:system_r:iptables_t:s0 Objets du contexte socket [ rawip_socket ] source modprobe Chemin de la source /sbin/modprobe Port <Inconnu> Hôte (removed) Paquetages RPM source module-init-tools-3.9-2.fc12 Paquetages RPM cible Politique RPM selinux-policy-3.6.30-2.fc12 Selinux activé True Type de politique targeted MLS activé True Mode strict Enforcing Nom du plugin leaks Nom de l'hôte (removed) Plateforme Linux (removed) 2.6.31-0.203.rc8.git2.fc12.x86_64 #1 SMP Fri Sep 4 21:33:05 EDT 2009 x86_64 x86_64 Compteur d'alertes 1 Première alerte sam. 05 sept. 2009 16:02:58 CEST Dernière alerte sam. 05 sept. 2009 16:02:58 CEST ID local 08915a03-0b63-46bd-8b72-6e5ef841588b Numéros des lignes Messages d'audit bruts node=(removed) type=AVC msg=audit(1252159378.537:38): avc: denied { read write } for pid=1885 comm="modprobe" path="socket:[15302]" dev=sockfs ino=15302 scontext=unconfined_u:system_r:insmod_t:s0 tcontext=unconfined_u:system_r:iptables_t:s0 tclass=rawip_socket node=(removed) type=SYSCALL msg=audit(1252159378.537:38): arch=c000003e syscall=59 success=yes exit=0 a0=14285b0 a1=7fff9f8a2d60 a2=7fff9f8a6560 a3=7fff9f8a2af0 items=0 ppid=1882 pid=1885 auid=0 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=tty1 ses=1 comm="modprobe" exe="/sbin/modprobe" subj=unconfined_u:system_r:insmod_t:s0 key=(null) audit2allow suggests: #============= insmod_t ============== allow insmod_t iptables_t:rawip_socket { read write };
iptables or its parent is leaking a file descriptor to a rawip_socket.
trigered by a simple # /etc/init.d/iptables status in a term
So looks like iptables command is leaking. fcntl(socketfd, F_SETFD, FD_CLOEXEC)
Fixed in rawhide in package iptables-1.4.5-1 or newer.
