Subject: strange audit messages from the dhcpc_t domain
Date: Sat, 02 Feb 2002 08:43:08 -0800 [thread overview]
Message-ID: <22613336.1012639388@localhost> (raw)
i just noticed a few strange denials on a RH 7.2 system running the
2.4.17-kernel
version. the machine is using DHCP on eth1 and gets assigned an address of
172.16.218.138.
1) Feb 1 04:02:05 fermat kernel: avc: denied { recvfrom } for pid=2235
exe=/usr/sbin/sendmail saddr=0.4.172.16 daddr=218.138.0.0 netif=eth1
scontext=system_u:system_r:dhcpc_t
tcontext=system_u:object_r:netmsg_eth1_t tclass=packet_socket
why is sendmail running in the dhcpc_t domain? and the saddr and daddr
values look
mangled.
2) Feb 2 02:37:10 fermat kernel: avc: denied { recvfrom } for
saddr=172.16.218.254 source=17680
daddr=172.16.218.138 dest=328
netif=eth1
scontext=system_u:system_r:dhcpc_t
tcontext=system_u:object_r:netmsg_eth1_t tclass=packet_socket
this looks correct, while
3) Feb 2 02:42:06 fermat kernel: avc: denied { recvfrom } for
saddr=0.8.172.16
daddr=218.1.0.0
netif=eth1 scontext=system_u:system_r:dhcpc_t
tcontext=system_u:object_r:netmsg_eth1_t
tclass=packet_socket
this also seems to have mangled the saddr/daddr fields (and if i reconstruct
the fields as 172.16.218.1, i don't think that machine would ever emit DHCP
or BOOTP messages, although i could be wrong).
