2020-09-24xfrm/compat: Add 32=>64-bit messages translatorDmitry Safonov
Provide the user-to-kernel translator under XFRM_USER_COMPAT, that creates for 32-bit xfrm-user message a 64-bit translation. The translation is afterwards reused by xfrm_user code just as if userspace had sent 64-bit message.

2020-09-24xfrm: Provide API to register translator moduleDmitry Safonov
Add a skeleton for xfrm_compat module and provide API to register it in xfrm_state.ko. struct xfrm_translator will have function pointers to translate messages received from 32-bit userspace or to be sent to it from 64-bit kernel. module_get()/module_put() are used instead of rcu_read_lock() as the module will vmalloc() memory for translation. The new API is registered with xfrm_state module, not with xfrm_user as the former needs translator for user_policy set by setsockopt() and xfrm_user already uses functions from xfrm_state.

2020-06-15esp, ah: modernize the crypto algorithm selectionsEric Biggers
The crypto algorithms selected by the ESP and AH kconfig options are out-of-date with the guidance of RFC 8221, which lists the legacy algorithms MD5 and DES as "MUST NOT" be implemented, and some more modern algorithms like AES-GCM and HMAC-SHA256 as "MUST" be implemented. But the options select the legacy algorithms, not the modern ones. Therefore, modify these options to select the MUST algorithms -- and *only* the MUST algorithms. Also improve the help text. Note that other algorithms may still be explicitly enabled in the kconfig, and the choice of which to actually use is still controlled by userspace. This change only modifies the list of algorithms for which kernel support is guaranteed to be present.

2020-04-28xfrm: add IPv6 support for espintcpSabrina Dubroca
This extends espintcp to support IPv6, building on the existing code and the new UDPv6 encapsulation support. Most of the code is either reused directly (stream parser, ULP) or very similar to the IPv4 variant (net/ipv6/esp6.c changes). The separation of config options for IPv4 and IPv6 espintcp requires a bit of Kconfig gymnastics to enable the core code.

2018-12-19xfrm: prefer secpath_set over secpath_dupFlorian Westphal
secpath_set is a wrapper for secpath_dup that will not perform an allocation if the secpath attached to the skb has a reference count of one, i.e., it doesn't need to be COW'ed. Also, secpath_dup doesn't attach the secpath to the skb, it leaves this to the caller. Use secpath_set in places that immediately assign the return value to skb. This allows to remove skb->sp without touching these spots again. secpath_dup can eventually be removed in followup patch. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: David S.

2018-10-31ixgbe/ixgbevf: fix XFRM_ALGO dependencyJeff Kirsher
Based on the original work from Arnd Bergmann. When XFRM_ALGO is not enabled, the new ixgbe IPsec code produces a link error: drivers/net/ethernet/intel/ixgbe/ixgbe_ipsec.o: In function `ixgbe_ipsec_vf_add_sa': ixgbe_ipsec.c:(.text+0x1266): undefined reference to `xfrm_aead_get_byname' Simply selecting XFRM_ALGO from here causes circular dependencies, so to fix it, we probably want this slightly more complex solution that is similar to what other drivers with XFRM offload do: A separate Kconfig symbol now controls whether we include the IPsec offload code. To keep the old behavior, this is left as 'default y'. The dependency in XFRM_OFFLOAD still causes a circular dependency but is not actually needed because this symbol is not user visible, so removing that dependency on top makes it all work.

git://git.kernel.org/pub/scm/linux/kernel/git/klassert/ipsec-next Steffen Klassert says: ==================== pull request (net-next): ipsec-next 2018-07-27 1) Extend the output_mark to also support the input direction and masking the mark values before applying to the skb. 2) Add a new lookup key for the upcomming xfrm interfaces. 3) Extend the xfrm lookups to match xfrm interface IDs. 4) Add virtual xfrm interfaces. The purpose of these interfaces is to overcome the design limitations that the existing VTI devices have. The main limitations that we see with the current VTI are the following: VTI interfaces are L3 tunnels with configurable endpoints. For xfrm, the tunnel endpoint are already determined by the SA. So the VTI tunnel endpoints must be either the same as on the SA or wildcards. In case VTI tunnel endpoints are same as on the SA, we get a one to one correlation between the SA and the tunnel. So each SA needs its own tunnel interface. On the other hand, we can have only one VTI tunnel with wildcard src/dst tunnel endpoints in the system because the lookup is based on the tunnel endpoints. The existing tunnel lookup won't work with multiple tunnels with wildcard tunnel endpoints. Some usecases require more than on VTI tunnel of this type, for example if somebody has multiple namespaces and every namespace requires such a VTI. VTI needs separate interfaces for IPv4 and IPv6 tunnels. So when routing to a VTI, we have to know to which address family this traffic class is going to be encapsulated. This is a lmitation because it makes routing more complex and it is not always possible to know what happens behind the VTI, e.g. when the VTI is move to some namespace. VTI works just with tunnel mode SAs. We need generic interfaces that ensures transfomation, regardless of the xfrm mode and the encapsulated address family. VTI is configured with a combination GRE keys and xfrm marks. With this we have to deal with some extra cases in the generic tunnel lookup because the GRE keys on the VTI are actually not GRE keys, the GRE keys were just reused for something else. All extensions to the VTI interfaces would require to add even more complexity to the generic tunnel lookup. So to overcome this, we developed xfrm interfaces with the following design goal: It should be possible to tunnel IPv4 and IPv6 through the same interface. No limitation on xfrm mode (tunnel, transport and beet). Should be a generic virtual interface that ensures IPsec transformation, no need to know what happens behind the interface. Interfaces should be configured with a new key that must match a new policy/SA lookup key. The lookup logic should stay in the xfrm codebase, no need to change or extend generic routing and tunnel lookups. Should be possible to use IPsec hardware offloads of the underlying interface. 5) Remove xfrm pcpu policy cache. This was added after the flowcache removal, but it turned out to make things even worse. From Florian Westphal. 6) Allow to update the set mark on SA updates. From Nathan Harold. 7) Convert some timestamps to time64_t. From Arnd Bergmann. 8) Don't check the offload_handle in xfrm code, it is an opaque data cookie for the driver. From Shannon Nelson. 9) Remove xfrmi interface ID from flowi. After this pach no generic code is touched anymore to do xfrm interface lookups. From Benedict Wong. 10) Allow to update the xfrm interface ID on SA updates. From Nathan Harold. 11) Don't pass zero to ERR_PTR() in xfrm_resolve_and_create_bundle. From YueHaibing. 12) Return more detailed errors on xfrm interface creation. From Benedict Wong. 13) Use PTR_ERR_OR_ZERO instead of IS_ERR + PTR_ERR.
