* SELinux fixups needed for preemptable RCU from -rtPaul E. McKenney2008-04-221-0/+2
| | | | | | | | | | | | The attached patch needs to move from -rt to mainline given preemptable RCU. This patch fixes SELinux code that implicitly assumes that disabling preemption prevents an RCU grace period from completing, an assumption that is valid for Classic RCU, but not necessarily for preemptable RCU. Explicit rcu_read_lock() calls are thus added. Signed-off-by: Paul E.

* SELinux: netif.c whitespace, syntax, and static declaraction cleanupsEric Paris2008-04-211-10/+9
| | | | | | | | | | | | | | | | | | | | This patch changes netif.c to fix whitespace and syntax issues. Things that are fixed may include (does not not have to include) whitespace at end of lines spaces followed by tabs spaces used instead of tabs spacing around parenthesis location of { around structs and else clauses location of * in pointer declarations removal of initialization of static data to keep it in the right section useless {} in if statemetns useless checking for NULL before kfree fixing of the indentation depth of switch statements and any number of other things I forgot to mention Signed-off-by: Eric Paris <eparis@redhat.com> Signed-off-by: James Morris <jmorris@namei.org>
* [NET] NETNS: Omit net_device->nd_net without CONFIG_NET_NS.YOSHIFUJI Hideaki2008-03-261-1/+1
| | | | | | | | Introduce per-net_device inlines: dev_net(), dev_net_set(). Without CONFIG_NET_NS, no namespace other than &init_net exists. Let's explicitly define them to help compiler optimizations. Signed-off-by: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org>
* SELinux: Add warning messages on network denial due to errorPaul Moore2008-01-301-2/+11
| | | | | | | | | | Currently network traffic can be sliently dropped due to non-avc errors which can lead to much confusion when trying to debug the problem. This patch adds warning messages so that when these events occur there is a user visible notification. Signed-off-by: Paul Moore <paul.moore@hp.com> Signed-off-by: James Morris <jmorris@namei.org>
* SELinux: Convert the netif code to use ifindex valuesPaul Moore2008-01-301-109/+145
| | | | | | | | | | | | 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".

* [NET]: Make device event notification network namespace safeEric W. Biederman2007-10-101-0/+4
| | | | | | | | | | | | | | | | | | Every user of the network device notifiers is either a protocol stack or a pseudo device. If a protocol stack that does not have support for multiple network namespaces receives an event for a device that is not in the initial network namespace it quite possibly can get confused and do the wrong thing. To avoid problems until all of the protocol stacks are converted this patch modifies all netdev event handlers to ignore events on devices that are not in the initial network namespace. As the rest of the code is made network namespace aware these checks can be removed. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* [PATCH] SELinux: convert to kzallocJames Morris2005-10-301-2/+1
| | | | | | | | | | | | | | | | | This patch converts SELinux code from kmalloc/memset to the new kazalloc unction. On i386, this results in a text saving of over 1K.

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!
