| * security: remove the security_netlink_recv hook as it is equivalent to capable()Eric Paris2012-01-051-1/+1
| | | | | | | | | | | | | | | | | | | | Once upon a time netlink was not sync and we had to get the effective capabilities from the skb that was being received. Today we instead get the capabilities from the current task. This has rendered the entire purpose of the hook moot as it is now functionally equivalent to the capable() call.

| * xfrm: Perform a replay check after return from async codepathsSteffen Klassert2011-09-211-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When asyncronous crypto algorithms are used, there might be many packets that passed the xfrm replay check, but the replay advance function is not called yet for these packets. So the replay check function would accept a replay of all of these packets. Also the system might crash if there are more packets in async processing than the size of the anti replay window, because the replay advance function would try to update the replay window beyond the bounds. This pach adds a second replay check after resuming from the async processing to fix these issues.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Upon "ip xfrm state update ..", xfrm_add_sa() takes an extra reference on the user-supplied SA and forgets to drop the reference when xfrm_state_update() returns 0. This leads to a memory leak as the parameter SA is never freed. This change attempts to fix the leak by calling __xfrm_state_put() when xfrm_state_update() updates a valid SA (err = 0). The parameter SA is added to the gc list when the final reference is dropped by xfrm_add_sa() upon completion.

| * xfrm: Don't allow esn with disabled anti replay detectionSteffen Klassert2011-05-101-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unlike the standard case, disabled anti replay detection needs some nontrivial extra treatment on ESN. RFC 4303 states: Note: If a receiver chooses to not enable anti-replay for an SA, then the receiver SHOULD NOT negotiate ESN in an SA management protocol. Use of ESN creates a need for the receiver to manage the anti-replay window (in order to determine the correct value for the high-order bits of the ESN, which are employed in the ICV computation), which is generally contrary to the notion of disabling anti-replay for an SA. So return an error if an ESN state with disabled anti replay detection is inserted for now and add the extra treatment later if we need it.

| * xfrm: Assign the inner mode output function to the dst entrySteffen Klassert2011-05-101-1/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As it is, we assign the outer modes output function to the dst entry when we create the xfrm bundle. This leads to two problems on interfamily scenarios. We might insert ipv4 packets into ip6_fragment when called from xfrm6_output. The system crashes if we try to fragment an ipv4 packet with ip6_fragment. This issue was introduced with git commit ad0081e4 (ipv6: Fragment locally generated tunnel-mode IPSec6 packets as needed). The second issue is, that we might insert ipv4 packets in netfilter6 and vice versa on interfamily scenarios. With this patch we assign the inner mode output function to the dst entry when we create the xfrm bundle. So xfrm4_output/xfrm6_output from the inner mode is used and the right fragmentation and netfilter functions are called. We switch then to outer mode with the output_finish functions.

* xfrm: Refcount destination entry on xfrm_lookupSteffen Klassert2011-03-161-0/+2
| | | | | | | | | | | | | | We return a destination entry without refcount if a socket policy is found in xfrm_lookup. This triggers a warning on a negative refcount when freeeing this dst entry. So take a refcount in this case to fix it. This refcount was forgotten when xfrm changed to cache bundles instead of policies for outgoing flows.
