Do you know which tool you were using when this happened? yep my son had unplugged my Linuxbox, so I had to reactivate the eth0 device via system-config-network BTW, even if it worked ok, I have seen flashing the same SELinux warning (AVC refusal, or perhaps denial) at least 3 more times in the following hours -- and I have always eliminated it without bothering too much, but why? I have run (as root, #) the suggestion to default it. Should I perhaps restart the machine before it applies? Thanks for inquiring This is a leak. You don't need to restart your machine after # grep /sbin/ip /var/log/audit/audit.log | audit2allow -D -M mypol # semodule -i mypol.pp which will dontaudit it for you. system-config-network should not be leaking file descriptors. Probably duplicate of bug #640475. *** This bug has been marked as a duplicate of bug 640475 *** |
SELinux is preventing /sbin/ip from read, write access on the netlink_route_socket netlink_route_socket. ***** Plugin leaks (50.5 confidence) suggests ****************************** If you want to ignore ip trying to read write access the netlink_route_socket netlink_route_socket, because you believe it should not need this access. Then you should report this as a bug. You can generate a local policy module to dontaudit this access. Do # grep /sbin/ip /var/log/audit/audit.log | audit2allow -D -M mypol # semodule -i mypol.pp ***** Plugin catchall (50.5 confidence) suggests *************************** If you believe that ip should be allowed read write access on the netlink_route_socket netlink_route_socket by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # grep ip /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context unconfined_u:system_r:ifconfig_t:s0-s0:c0.c1023 Target Context unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1 023 Target Objects netlink_route_socket [ netlink_route_socket ] Source ip Source Path /sbin/ip Port <Sconosciuto> Host (removed) Source RPM Packages iproute-2.6.35-6.fc14 Target RPM Packages Policy RPM selinux-policy-3.9.7-29.fc14 Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Host Name (removed) Platform Linux (removed) 2.6.35.11-83.fc14.x86_64 #1 SMP Mon Feb 7 07:06:44 UTC 2011 x86_64 x86_64 Alert Count 2 First Seen mar 15 feb 2011 21:59:49 CET Last Seen mar 15 feb 2011 21:59:51 CET Local ID d65cbbde-5214-456c-ad46-75978b8ae710 Raw Audit Messages type=AVC msg=audit(1297803591.599:28212): avc: denied { read write } for pid=13416 comm="ip" path="socket:[215080]" dev=sockfs ino=215080 scontext=unconfined_u:system_r:ifconfig_t:s0-s0:c0.c1023 tcontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tclass=netlink_route_socket type=SYSCALL msg=audit(1297803591.599:28212): arch=x86_64 syscall=execve success=yes exit=0 a0=127d4e0 a1=125fe70 a2=12667c0 a3=8 items=0 ppid=13397 pid=13416 auid=500 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=1 comm=ip exe=/sbin/ip subj=unconfined_u:system_r:ifconfig_t:s0-s0:c0.c1023 key=(null) Hash: ip,ifconfig_t,unconfined_t,netlink_route_socket,read,write audit2allow #============= ifconfig_t ============== #!!!!
