Joe Stringer says: ==================== OVS conntrack fixes for net The userspace side of the Open vSwitch conntrack changes is currently undergoing review, which has highlighted some minor bugs in the existing conntrack implementation in the kernel, as well as pointing out some future-proofing that can be done on the interface to reduce the need for additional compatibility code in future. The biggest changes here are to the userspace API for the ct_state match field and the CT action. This series proposes to firstly extend the ct_state match field to 32 bits, ensuring to reject any currently unsupported bits. Secondly, rather than representing CT action flags within a 32-bit field, simply use a netlink attribute as presence of the single flag that is defined today. This also serves to reject unsupported ct action flag bits. v4: Use 12-character abbreviated hashes in commit messages. v3: Fully acked. v2: Address minor style feedback, add acks. v1: Initial post. ==================== Signed-off-by: -
Joe Stringer authored
Previously, the CT_ATTR_FLAGS attribute, when nested under the OVS_ACTION_ATTR_CT, encoded a 32-bit bitmask of flags that modify the semantics of the ct action. It's more extensible to just represent each flag as a nested attribute, and this requires no additional error checking to reject flags that aren't currently supported. Suggested-by:

The ct_state field was initially added as an 8-bit field, however six of the bits are already being used and use cases are already starting to appear that may push the limits of this field. This patch extends the field to 32 bits while retaining the internal representation of 8 bits. This should cover forward compatibility of the ABI for the foreseeable future. This patch also reorders the OVS_CS_F_* bits to be sequential. Suggested-by:

Previously, if userspace specified ct_state bits in the flow key which are currently undefined (and therefore unsupported), then they would be ignored. This could cause unexpected behaviour in future if userspace is extended to support additional bits but attempts to communicate with the current version of the kernel. This patch rectifies the situation by rejecting such ct_state bits. Fixes: 7f8a436e "openvswitch: Add conntrack action" Signed-off-by:

Neil Armstrong says: ==================== net: dsa: complete and fix the dsa unbinding In order to cleanly unbind the dsa core, either as a module removal, or a platform device unbind, switch the allocation the their devm_ counterparts and complete the destroy functions. First, the missing kfree were added, the remove function were completed then kfree were removed in favor to devm_ calls. The last patch is an way to cleanly exit the probe when no switch is found in the discover process. The patches are based on the current net. v3: - make checkpatch happy with 1/5 & 5/5 - fix 5/5 exit path with a goto ==================== Signed-off-by: -

It occurred to me yesterday that 741a11d9 ("net: ipv6: Add RT6_LOOKUP_F_IFACE flag if oif is set") means that xfrm6_dst_lookup needs the FLOWI_FLAG_SKIP_NH_OIF flag set. This latest commit causes the oif to be considered in lookups which is known to break vti. This explains why 58189ca7 did not the IPv6 change at the time it was submitted.

Without this patch, if the only instructions using r_X are of the BPF_LD | BPF_IND type, r_X would not be reset to 0, using whatever value was there when entering the jited code. With this patch, r_X will be correctly marked as used so it will be reset to 0 in the prologue code.

However, sk_get_filter() wasn't updated to test for this at the time when eBPF could be attached. Just throw an error to the user to indicate that eBPF cannot be dumped over this interface. That way, it can also be known that a program _is_ attached (as opposed to just return 0), and a different (future) method needs to be consulted for a dump.

After commit 1ce87720 ("net: sched: make cls_u32 lockless") we began to release tc actions in a RCU callback. However, mirred action relies on RTNL lock to protect the global mirred_list, therefore we could have a race condition between RCU callback and netdevice event, which caused a list corruption as reported by Vinson. Instead of relying on RTNL lock, introduce a spinlock to protect this list. Note, in non-bind case, it is still called with RTNL lock, therefore should disable BH too. Reported-by:
