* xfrm: Add security check before flushing SAD/SPDJoy Latten2007-06-07
| | | | | | | | | | | | | | | | | | | | | | | Currently we check for permission before deleting entries from SAD and SPD, (see security_xfrm_policy_delete() security_xfrm_state_delete()) However we are not checking for authorization when flushing the SPD and the SAD completely. It was perhaps missed in the original security hooks patch. This patch adds a security check when flushing entries from the SAD and SPD. It runs the entire database and checks each entry for a denial. If the process attempting the flush is unable to remove all of the entries a denial is logged the the flush function returns an error without removing anything. This is particularly useful when a process may need to create or delete its own xfrm entries used for things like labeled networking but that same process should not be able to delete other entries or flush the entire database.

| | | | | | | | | | | | | | | | On a system with a lot of SAs, counting SAD entries chews useful CPU time since you need to dump the whole SAD to user space; i.e something like ip xfrm state ls | grep -i src | wc -l I have seen taking literally minutes on a 40K SAs when the system is swapping. With this patch, some of the SAD info (that was already being tracked) is exposed to user space. i.e you do: ip xfrm state count And you get the count; you can also pass -s to the command line and get the hash info.

* [NETLINK]: Remove error pointer from netlink message handlerThomas Graf2007-04-26
| | | | | | | | | | | | | | | | | | The error pointer argument in netlink message handlers is used to signal the special case where processing has to be interrupted because a dump was started but no error happened. Instead it is simpler and more clear to return -EINTR and have netlink_run_queue() deal with getting the queue right. nfnetlink passed on this error pointer to its subsystem handlers but only uses it to signal the start of a netlink dump. Therefore it can be removed there as well. This patch also cleans up the error handling in the affected message handlers to be consistent since it had to be touched anyway.

* [IPSEC]: xfrm_policy delete security check misplacedEric Paris2007-03-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The security hooks to check permissions to remove an xfrm_policy were actually done after the policy was removed. Since the unlinking and deletion are done in xfrm_policy_by* functions this moves the hooks inside those 2 functions. There we have all the information needed to do the security check and it can be done before the deletion. Since auditing requires the result of that security check err has to be passed back and forth from the xfrm_policy_by* functions. This patch also fixes a bug where a deletion that failed the security check could cause improper accounting on the xfrm_policy (xfrm_get_policy didn't have a put on the exit path for the hold taken by xfrm_policy_by*) It also fixes the return code when no policy is found in xfrm_add_pol_expire. In old code (at least back in the 2.6.18 days) err wasn't used before the return when no policy is found and so the initialization would cause err to be ENOENT. But since err has since been used above when we don't get a policy back from the xfrm_policy_by* function we would always return 0 instead of the intended ENOENT. Also fixed some white space damage in the same area.

* IPsec: correct semantics for SELinux policy matchingVenkat Yekkirala2006-10-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently when an IPSec policy rule doesn't specify a security context, it is assumed to be "unlabeled" by SELinux, and so the IPSec policy rule fails to match to a flow that it would otherwise match to, unless one has explicitly added an SELinux policy rule allowing the flow to "polmatch" to the "unlabeled" IPSec policy rules. In the absence of such an explicitly added SELinux policy rule, the IPSec policy rule fails to match and so the packet(s) flow in clear text without the otherwise applicable xfrm(s) applied. The above SELinux behavior violates the SELinux security notion of "deny by default" which should actually translate to "encrypt by default" in the above case. This was first reported by Evgeniy Polyakov and the way James Morris was seeing the problem was when connecting via IPsec to a confined service on an SELinux box (vsftpd), which did not have the appropriate SELinux policy permissions to send packets via IPsec. With this patch applied, SELinux "polmatching" of flows Vs. IPSec policy rules will only come into play when there's a explicit context specified for the IPSec policy rule (which also means there's corresponding SELinux policy allowing appropriate domains/flows to polmatch to this context). Secondly, when a security module is loaded (in this case, SELinux), the security_xfrm_policy_lookup() hook can return errors other than access denied, such as -EINVAL. We were not handling that correctly, and in fact inverting the return logic and propagating a false "ok" back up to xfrm_lookup(), which then allowed packets to pass as if they were not associated with an xfrm policy. The solution for this is to first ensure that errno values are correctly propagated all the way back up through the various call chains from security_xfrm_policy_lookup(), and handled correctly. Then, flow_cache_lookup() is modified, so that if the policy resolver fails (typically a permission denied via the security module), the flow cache entry is killed rather than having a null policy assigned (which indicates that the packet can pass freely). This also forces any future lookups for the same flow to consult the security module (e.g. SELinux) for current security policy (rather than, say, caching the error on the flow cache entry). This patch: Fix the selinux side of things. This makes sure SELinux polmatching of flow contexts to IPSec policy rules comes into play only when an explicit context is associated with the IPSec policy rule. Also, this no longer defaults the context of a socket policy to the context of the socket since the "no explicit context" case is now handled properly.

* [MLSXFRM]: Add security context to acquire messages using netlinkSerge Hallyn2006-09-22
| | | | | | | | | | | This includes the security context of a security association created for use by IKE in the acquire messages sent to IKE daemons using netlink/xfrm_user. This would allow the daemons to include the security context in the negotiation, so that the resultant association is unique to that security context.
