Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

SELinux: Convert the netif code to use ifindex values The current SELinux netif code requires the caller have a valid net_device struct pointer to lookup network interface information. However, we don't always have a valid net_device pointer so convert the netif code to use the ifindex values we always have as part of the sk_buff. This patch also removes the default message SID from the network interface record, it is not being used and therefore is "dead code".

selinux: make the netif cache namespace aware While SELinux largely ignores namespaces, for good reason, there are some places where it needs to at least be aware of namespaces in order to function correctly. Network namespaces are one example. Basic awareness of network namespaces are necessary in order to match a network interface's index number to an actual network device. This patch corrects a problem with network interfaces added to a non-init namespace, and can be reproduced with the following commands: [NOTE: the NetLabel configuration is here only to active the dynamic networking controls ] # netlabelctl unlbl add default address:0.0.0.0/0 \ label:system_u:object_r:unlabeled_t:s0 # netlabelctl unlbl add default address:::/0 \ label:system_u:object_r:unlabeled_t:s0 # netlabelctl cipsov4 add pass doi:100 tags:1 # netlabelctl map add domain:lspp_test_netlabel_t \ protocol:cipsov4,100 # ip link add type veth # ip netns add myns # ip link set veth1 netns myns # ip a add dev veth0 10.250.13.100/24 # ip netns exec myns ip a add dev veth1 10.250.13.101/24 # ip l set veth0 up # ip netns exec myns ip l set veth1 up # ping -c 1 10.250.13.101 # ip netns exec myns ping -c 1 10.250.13.100 Reported-by: Jiri Jaburek <jjaburek@redhat.com> Signed-off-by: Paul Moore <pmoore@redhat.com>

selinux: reduce the number of calls to synchronize_net() when flushing caches When flushing the AVC, such as during a policy load, the various network caches are also flushed, with each making a call to synchronize_net() which has shown to be expensive in some cases. This patch consolidates the network cache flushes into a single AVC callback which only calls synchronize_net() once for each AVC cache flush.
