2008-01-28[XFRM]: Drop packets when replay counter would overflowPaul Moore
According to RFC4303, section 3.3.3 we need to drop outgoing packets which cause the replay counter to overflow: 3.3.3. Sequence Number Generation The sender's counter is initialized to 0 when an SA is established. The sender increments the sequence number (or ESN) counter for this SA and inserts the low-order 32 bits of the value into the Sequence Number field. Thus, the first packet sent using a given SA will contain a sequence number of 1. If anti-replay is enabled (the default), the sender checks to ensure that the counter has not cycled before inserting the new value in the Sequence Number field. In other words, the sender MUST NOT send a packet on an SA if doing so would cause the sequence number to cycle. An attempt to transmit a packet that would result in sequence number overflow is an auditable event. The audit log entry for this event SHOULD include the SPI value, current date/time, Source Address, Destination Address, and (in IPv6) the cleartext Flow ID.

2008-01-28[XFRM]: RFC4303 compliant auditingPaul Moore
This patch adds a number of new IPsec audit events to meet the auditing requirements of RFC4303. This includes audit hooks for the following events: * Could not find a valid SA [sections 2.1, 3.4.2] . xfrm_audit_state_notfound() . xfrm_audit_state_notfound_simple() * Sequence number overflow [section 3.3.3] . xfrm_audit_state_replay_overflow() * Replayed packet [section 3.4.3] . xfrm_audit_state_replay() * Integrity check failure [sections 3.4.4.1, 3.4.4.2] . xfrm_audit_state_icvfail() While RFC4304 deals only with ESP most of the changes in this patch apply to IPsec in general, i.e. both AH and ESP. The one case, integrity check failure, where ESP specific code had to be modified the same was done to the AH code for the sake of consistency.

2008-01-28[IPSEC]: Do xfrm_state_check_space before encapsulationHerbert Xu
While merging the IPsec output path I moved the encapsulation output operation to the top of the loop so that it sits outside of the locked section. Unfortunately in doing so it now sits in front of the space check as well which could be a fatal error.

2008-01-28[XFRM]: Fix potential race vs xfrm_state(only)_find and xfrm_hash_resize.Pavel Emelyanov
The _find calls calculate the hash value using the xfrm_state_hmask, without the xfrm_state_lock. But the value of this mask can change in the _resize call under the state_lock, so we risk to fail in finding the desired entry in hash. I think, that the hash value is better to calculate under the state lock. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-01-28[IPSEC]: Fix zero return value in xfrm_lookup on errorHerbert Xu
Further testing shows that my ICMP relookup patch can cause xfrm_lookup to return zero on error which isn't very nice since it leads to the caller dying on null pointer dereference. The bug is due to not setting err to ENOENT just before we leave xfrm_lookup in case of no policy. This patch moves the err setting to where it should be.

2008-01-28[IPSEC]: Add ICMP host relookup supportHerbert Xu
RFC 4301 requires us to relookup ICMP traffic that does not match any policies using the reverse of its payload. This patch implements this for ICMP traffic that originates from or terminates on localhost. This is activated on outbound with the new policy flag XFRM_POLICY_ICMP, and on inbound by the new state flag XFRM_STATE_ICMP. On inbound the policy check is now performed by the ICMP protocol so that it can repeat the policy check where necessary.

2008-01-28[IPSEC]: Make xfrm_lookup flags argument a bit-fieldHerbert Xu
This patch introduces an enum for bits in the flags argument of xfrm_lookup. This is so that we can cram more information into it later. Since all current users use just the values 0 and 1, XFRM_LOOKUP_WAIT has been added with the value 1 << 0 to represent the current meaning of flags.

2008-01-28[IPSEC]: SPD auditing fix to include the netmask/prefix-lengthPaul Moore
Currently the netmask/prefix-length of an IPsec SPD entry is not included in any of the SPD related audit messages. This can cause a problem when the audit log is examined as the netmask/prefix-length is vital in determining what network traffic is affected by a particular SPD entry. This patch fixes this problem by adding two additional fields, "src_prefixlen" and "dst_prefixlen", to the SPD audit messages to indicate the source and destination netmasks. These new fields are only included in the audit message when the netmask/prefix-length is less than the address length, i.e. the SPD entry applies to a network address and not a host address. Example audit message: type=UNKNOWN[1415] msg=audit(1196105849.752:25): auid=0 \ subj=root:system_r:unconfined_t:s0-s0:c0.c1023 op=SPD-add res=1 \ src=192.168.0.0 src_prefixlen=24 dst=192.168.1.0 dst_prefixlen=24 In addition, this patch also fixes a few other things in the xfrm_audit_common_policyinfo() function. The IPv4 string formatting was converted to use the standard NIPQUAD_FMT constant, the memcpy() was removed from the IPv6 code path and replaced with a typecast (the memcpy() was acting as a slow, implicit typecast anyway), and two local variables were created to make referencing the XFRM security context and selector information cleaner.

2008-01-28[IPSEC]: Add async resume support on inputHerbert Xu

2008-01-28[IPSEC]: Remove nhoff from xfrm_inputHerbert Xu
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.

2008-01-28[IPSEC]: Make x->lastused an unsigned longHerbert Xu
Currently x->lastused is u64 which means that it cannot be read/written atomically on all architectures. David Miller observed that the value stored in it is only an unsigned long which is always atomic. So based on his suggestion this patch changes the internal representation from u64 to unsigned long while the user-interface still refers to it as u64.

2008-01-28[IPSEC]: Move state lock into x->type->inputHerbert Xu

2008-01-28[IPSEC]: Move integrity stat collection into xfrm_inputHerbert Xu
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. In future this error can be directly returned by the crypto layer once we switch to aead algorithms. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

2008-01-28[IPSEC]: Store xfrm states in security path directlyHerbert Xu
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.

2008-01-28[IPSEC]: Separate inner/outer mode processing on inputHerbert Xu
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.

2008-01-28[IPSEC]: Move x->outer_mode->output out of locked sectionHerbert Xu
RO mode is the only one that requires a locked output function. So it's easier to move the lock into that function rather than requiring everyone else to run under the lock. In particular, this allows us to move the size check into the output function without causing a potential dead-lock should the ICMP error somehow hit the same SA on transmission.

Half of the code in xfrm4_bundle_create and xfrm6_bundle_create are common. This patch extracts that logic and puts it into xfrm_bundle_create. The rest of it are then accessed through afinfo. As a result this fixes the problem with inter-family transforms where we treat every xfrm dst in the bundle as if it belongs to the top family.
