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

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.

My @hp.com will no longer be valid starting August 5, 2011 so an update is
necessary. My new email address is employer independent so we don't have
to worry about doing this again any time soon.

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".

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!
