* [MLSXFRM]: Define new SELinux service routineVenkat Yekkirala2006-09-221-0/+69
| | | | | | | | | | | This defines a routine that combines the Type Enforcement portion of one sid with the MLS portion from the other sid to arrive at a new sid. This would be used to define a sid for a security association that is to be negotiated by IKE as well as for determing the sid for open requests and connection-oriented child sockets.

* [PATCH] support for context based audit filteringDarrel Goeddel2006-05-011-1/+234
| | | | | | | | | | | | | The following patch provides selinux interfaces that will allow the audit system to perform filtering based on the process context (user, role, type, sensitivity, and clearance). These interfaces will allow the selinux module to perform efficient matches based on lower level selinux constructs, rather than relying on context retrievals and string comparisons within the audit module. It also allows for dominance checks on the mls portion of the contexts that are impossible with only string comparisons.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a gfp_mask to audit_log_start() and audit_log(), to reduce the amount of GFP_ATOMIC allocation -- most of it doesn't need to be GFP_ATOMIC. Also if the mask includes __GFP_WAIT, then wait up to 60 seconds for the auditd backlog to clear instead of immediately abandoning the message. The timeout should probably be made configurable, but for now it'll suffice that it only happens if auditd is actually running. Signed-off-by: David Woodhouse <dwmw2@infradead.org>
* | | | [PATCH] selinux: Reduce memory use by avtabStephen Smalley2005-09-051-35/+41
| |_|/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch improves memory use by SELinux by both reducing the avtab node size and reducing the number of avtab nodes. The memory savings are substantial, e.g. on a 64-bit system after boot, James Morris reported the following data for the targeted and strict policies: #objs objsize kernmem Targeted: Before: 237888 40 9.1MB After: 19968 24 468KB Strict: Before: 571680 40 21.81MB After: 221052 24 5.06MB The improvement in memory use comes at a cost in the speed of security server computations of access vectors, but these computations are only required on AVC cache misses, and performance measurements by James Morris using a number of benchmarks have shown that the change does not cause any significant degradation. Note that a rebuilt policy via an updated policy toolchain (libsepol/checkpolicy) is required in order to gain the full benefits of this patch, although some memory savings benefits are immediately applied even to older policies (in particular, the reduction in avtab node size). Sources for the updated toolchain are presently available from the sourceforge CVS tree (http://sourceforge.net/cvs/?group_id=21266), and tarballs are available from http://www.flux.utah.edu/~sds.

* | | [PATCH] SELinux: default labeling of MLS fieldJames Morris2005-07-281-13/+42
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement kernel labeling of the MLS (multilevel security) field of security contexts for files which have no existing MLS field. This is to enable upgrades of a system from non-MLS to MLS without performing a full filesystem relabel including all of the mountpoints, which would be quite painful for users. With this patch, with MLS enabled, if a file has no MLS field, the kernel internally adds an MLS field to the in-core inode (but not to the on-disk file). This MLS field added is the default for the superblock, allowing per-mountpoint control over the values via fixed policy or mount options. This patch has been tested by enabling MLS without relabeling its filesystem, and seems to be working correctly.

| * [PATCH] selinux: fix avc_alloc_node() oom with no policy loadedStephen Smalley2005-05-171-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch should fix the avc_alloc_node() oom condition that Andrew reported when no policy is loaded in SELinux. Prior to this patch, when no policy was loaded, the SELinux "security server" (policy engine) was only returning allowed decisions for the requested permissions for each access check. This caused the cache to thrash when trying to use SELinux for real work with no policy loaded (typically, the no policy loaded state is only for bootstrapping to the point where we can load an initial policy). This patch changes the SELinux security server to return the complete allowed access vector at once, and then to reset the cache after the initial policy load to flush the initial cache state created during bootstrapping.

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!
