* xfrm: Fix crash observed during device unregistration and decryptionsubashab@codeaurora.org2016-03-241-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A crash is observed when a decrypted packet is processed in receive path. get_rps_cpus() tries to dereference the skb->dev fields but it appears that the device is freed from the poison pattern.

| | | | | | | | | | | | | | | | | | When host ping its peer, ICMP echo request packet triggers IPsec policy, then host negotiates SA secret with its peer. After IKE installed SA for OUT direction, but before SA for IN direction installed, host get ICMP echo reply from its peer. At the time being, the SA state for IN direction could be XFRM_STATE_ACQ, then the received packet will be dropped after adding LINUX_MIB_XFRMINSTATEINVALID statistic. Adding a LINUX_MIB_XFRMACQUIREERROR statistic counter for such scenario when SA in larval state is much clearer for user than LINUX_MIB_XFRMINSTATEINVALID which indicates the SA is totally bad.

* xfrm: Workaround incompatibility of ESN and async cryptoSteffen Klassert2012-09-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | ESN for esp is defined in RFC 4303. This RFC assumes that the sequence number counters are always up to date. However, this is not true if an async crypto algorithm is employed. If the sequence number counters are not up to date on sequence number check, we may incorrectly update the upper 32 bit of the sequence number. This leads to a DOS. We workaround this by comparing the upper sequence number, (used for authentication) with the upper sequence number computed after the async processing. We drop the packet if these numbers are different. To do this, we introduce a recheck function that does this check in the ESN case.

* 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.

In this case we leave the rcu protected region, so force a refcount on the skb's destination entry before we enter the xfrm type input/output handlers. This fixes a crash when a route is deleted whilst sending IPsec data that is transformed by an asynchronous algorithm.

| | | | | | | | | | | | | | | | | | The nhoff field isn't actually necessary in xfrm_input. For tunnel mode transforms we now throw away the output IP header so it makes no sense to fill in the nexthdr field. For transport mode we can now let the function transport_finish do the setting and it knows where the nexthdr field is. The only other thing that needs the nexthdr field to be set is the header extraction code. However, we can simply move the protocol extraction out of the generic header extraction. We want to minimise the amount of info we have to carry around between transforms as this simplifies the resumption process for async crypto.

| | | | | | | | | | | | | | | | Similar to the moving out of the replay processing on the output, this patch moves the integrity stat collectin from x->type->input into xfrm_input. This would eventually allow transforms such as AH/ESP to be lockless. The error value EBADMSG (currently unused in the crypto layer) is used to indicate a failed integrity check.

* [IPSEC]: Store xfrm states in security path directlyHerbert Xu2008-01-281-27/+15
| | | | | | | | | | | | | | As it is xfrm_input first collects a list of xfrm states on the stack before storing them in the packet's security path just before it returns. For async crypto, this construction presents an obstacle since we may need to leave the loop after each transform. In fact, it's much easier to just skip the stack completely and always store to the security path. This is proven by the fact that this patch actually shrinks the code.

* [IPSEC]: Separate inner/outer mode processing on inputHerbert Xu2008-01-281-0/+13
| | | | | | | | | | | | | | | | | | | With inter-family transforms the inner mode differs from the outer mode. Attempting to handle both sides from the same function means that it needs to handle both IPv4 and IPv6 which creates duplication and confusion. This patch separates the two parts on the input path so that each function deals with one family only. In particular, the functions xfrm4_extract_inut/xfrm6_extract_inut moves the pertinent fields from the IPv4/IPv6 IP headers into a neutral format stored in skb->cb. This is then used by the inner mode input functions to modify the inner IP header. In this way the input function no longer has to know about the outer address family.
