xfrm: call xfrm_dev_policy_delete when kill policy

2024-08-03T06:59:44Z

[ Upstream commit 89a2aefe4b084686c2ffc1ee939585111ea4fc0f ] xfrm_policy_kill() is called at different places to delete xfrm policy. It will call xfrm_pol_put(). But xfrm_dev_policy_delete() is not called to free the policy offloaded to hardware. The three commits cited here are to handle this issue by calling xfrm_dev_policy_delete() outside xfrm_get_policy(). But they didn't cover all the cases. An example, which is not handled for now, is xfrm_policy_insert(). It is called when XFRM_MSG_UPDPOLICY request is received. Old policy is replaced by new one, but the offloaded policy is not deleted, so driver doesn't have the chance to release hardware resources. To resolve this issue for all cases, move xfrm_dev_policy_delete() into xfrm_policy_kill(), so the offloaded policy can be deleted from hardware when it is called, which avoids hardware resources leakage.

xfrm: fix netdev reference count imbalance

2024-08-03T06:59:43Z

[ Upstream commit 9199b915e9fad7f5eff6160d24ff6b38e970107d ] In cited commit, netdev_tracker_alloc() is called for the newly allocated xfrm state, but dev_hold() is missed, which causes netdev reference count imbalance, because netdev_put() is called when the state is freed in xfrm_dev_state_free(). Fix the issue by replacing netdev_tracker_alloc() with netdev_hold().

xfrm: Fix unregister netdevice hang on hardware offload.

2024-08-03T06:59:40Z

[ Upstream commit 07b87f9eea0c30675084d50c82532d20168da009 ] When offloading xfrm states to hardware, the offloading device is attached to the skbs secpath. If a skb is free is deferred, an unregister netdevice hangs because the netdevice is still refcounted. Fix this by removing the netdevice from the xfrm states when the netdevice is unregistered. To find all xfrm states that need to be cleared we add another list where skbs linked to that are unlinked from the lists (deleted) but not yet freed.

xfrm: Log input direction mismatch error in one place

2024-08-03T06:59:39Z

[ Upstream commit 15f5fe9e84839dcc9eaa69b08ced9d24cb464369 ] Previously, the offload data path decrypted the packet before checking the direction, leading to error logging and packet dropping. However, dropped packets wouldn't be visible in tcpdump or audit log. With this fix, the offload path, upon noticing SA direction mismatch, will pass the packet to the stack without decrypting it. The L3 layer will then log the error, audit, and drop ESP without decrypting or decapsulating it. This also ensures that the slow path records the error and audit log, making dropped packets visible in tcpdump.

net: fix __dst_negative_advice() race

2024-05-30T00:34:49Z

__dst_negative_advice() does not enforce proper RCU rules when sk->dst_cache must be cleared, leading to possible UAF. RCU rules are that we must first clear sk->sk_dst_cache, then call dst_release(old_dst). Note that sk_dst_reset(sk) is implementing this protocol correctly, while __dst_negative_advice() uses the wrong order. Given that ip6_negative_advice() has special logic against RTF_CACHE, this means each of the three ->negative_advice() existing methods must perform the sk_dst_reset() themselves. Note the check against NULL dst is centralized in __dst_negative_advice(), there is no need to duplicate it in various callbacks. Many thanks to Clement Lecigne for tracking this issue. This old bug became visible after the blamed commit, using UDP sockets.

rtnetlink: allow rtnl_fill_link_netnsid() to run under RCU protection

2024-05-07T09:14:50Z

We want to be able to run rtnl_fill_ifinfo() under RCU protection instead of RTNL in the future. All rtnl_link_ops->get_link_net() methods already using dev_net() are ready. I added READ_ONCE() annotations on others. Signed-off-by: Eric Dumazet Reviewed-by: Simon Horman Signed-off-by: Paolo Abeni

Steffen Klassert says: ==================== pull request (net-next): ipsec-next 2024-05-03 1) Remove Obsolete UDP_ENCAP_ESPINUDP_NON_IKE Support. This was defined by an early version of an IETF draft that did not make it to a standard. 2) Introduce direction attribute for xfrm states. xfrm states have a direction, a stsate can be used either for input or output packet processing. Add a direction to xfrm states to make it clear for what a xfrm state is used. * tag 'ipsec-next-2024-05-03' of git://git.kernel.org/pub/scm/linux/kernel/git/klassert/ipsec-next: xfrm: Restrict SA direction attribute to specific netlink message types xfrm: Add dir validation to "in" data path lookup xfrm: Add dir validation to "out" data path lookup xfrm: Add Direction to the SA in or out udpencap: Remove Obsolete UDP_ENCAP_ESPINUDP_NON_IKE Support ==================== Link: https://lore.kernel.org/r/20240503082732.2835810-1-steffen.klassert@secunet.com Signed-off-by: Jakub Kicinski
