Rejecting non-native endian BTF overlapped with the addition of support for it. The rest were more simple overlapping changes, except the renesas ravb binding update, which had to follow a file move as well as a YAML conversion. Signed-off-by: David S. Miller

xfrm/compat: Translate 32-bit user_policy from sockptr

2020-09-24T06:53:04+00:00

Provide compat_xfrm_userpolicy_info translation for xfrm setsocketopt(). Reallocate buffer and put the missing padding for 64-bit message. Signed-off-by: Dmitry Safonov Signed-off-by: Steffen Klassert

xfrm/compat: Add 32=>64-bit messages translator

2020-09-24T06:53:03+00:00

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. Signed-off-by: Dmitry Safonov Signed-off-by: Steffen Klassert

xfrm/compat: Add 64=>32-bit messages translator

2020-09-24T06:53:03+00:00

Provide the kernel-to-user translator under XFRM_USER_COMPAT, that creates for 64-bit xfrm-user message a 32-bit translation and puts it in skb's frag_list. net/compat.c layer provides MSG_CMSG_COMPAT to decide if the message should be taken from skb or frag_list. (used by wext-core which has also an ABI difference) Kernel sends 64-bit xfrm messages to the userspace for: - multicast (monitor events) - netlink dumps Wire up the translator to xfrm_nlmsg_multicast().

xfrm: Provide API to register translator module

2020-09-24T06:53:03+00:00

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.

xfrm: clone XFRMA_REPLAY_ESN_VAL in xfrm_do_migrate

2020-09-07T10:45:22+00:00

XFRMA_REPLAY_ESN_VAL was not cloned completely from the old to the new.

Steffen Klassert says: ==================== pull request (net-next): ipsec-next 2020-07-30 Please note that I did the first time now --no-ff merges of my testing branch into the master branch to include the [PATCH 0/n] message of a patchset. Please let me know if this is desirable, or if I should do it any different. 1) Introduce a oseq-may-wrap flag to disable anti-replay protection for manually distributed ICVs as suggested in RFC 4303. From Petr Vaněk. 2) Patchset to fully support IPCOMP for vti4, vti6 and xfrm interfaces. From Xin Long. 3) Switch from a linear list to a hash list for xfrm interface lookups. From Eyal Birger. 4) Fixes to not register one xfrm(6)_tunnel object twice. From Xin Long. 5) Fix two compile errors that were introduced with the IPCOMP support for vti and xfrm interfaces. Also from Xin Long. 6) Make the policy hold queue work with VTI. This was forgotten when VTI was implemented. Please pull or let me know if there are problems. ==================== Signed-off-by: David S. Miller

net/xfrm: switch xfrm_user_policy to sockptr_t

xfrm: Fix crash when the hold queue is used.

2020-07-21T06:33:56+00:00

The commits "xfrm: Move dst->path into struct xfrm_dst" and "net: Create and use new helper xfrm_dst_child()." changed xfrm bundle handling under the assumption that xdst->path and dst->child are not a NULL pointer only if dst->xfrm is not a NULL pointer. That is true with one exception. If the xfrm hold queue is used to wait until a SA is installed by the key manager, we create a dummy bundle without a valid dst->xfrm pointer. The current xfrm bundle handling crashes in that case. Fix this by extending the NULL check of dst->xfrm with a test of the DST_XFRM_QUEUE flag. Fixes: 0f6c480f23f4 ("xfrm: Move dst->path into struct xfrm_dst") Fixes: b92cf4aab8e6 ("net: Create and use new helper xfrm_dst_child().") Signed-off-by: Steffen Klassert
