I found the latest net-next kernel calls dsa_slave_port_obj_del() multiple
times,
one for each port, with host port as the parameter.
As the base driver cannot find an entry with that host port, it returns an error
and so users will see a lot of failures from the DSA switch.

This allows sending GSO maximum values when configuring a device.
The values are advisory. Most devices will ignore them but for some
pseudo devices such as veth pairs they can be set.

Similar to erspan collect_md mode in ipv4, the first patch adds
support for ip6erspan collect metadata mode. The second patch
adds the test case using bpf_skb_[gs]et_tunnel_key helpers.
The corresponding iproute2 patch:

The patch adds 'external' option to support collect metadata
gre6 tunnel. Example of L3 and L2 gre device:

Currently, a nlmon link inside a child namespace can observe systemwide
netlink activity. Filter the traffic so that in a non-init netns,
nlmon can only sniff netlink messages from its own netns.
Test case:
vpnns -- bash -c "ip link add nlmon0 type nlmon; \
ip link set

Creating a sandbox environment with namespaces is challenging
considering what these sandboxed processes can engage into. e.g.
CVE-2017-6074, CVE-2017-7184, CVE-2017-7308 etc. just to name few.
Current form of user-namespaces, however, if changed
From: Mahesh Bandewar
Add a sysctl variable kernel.controlled_userns_caps_whitelist. This
takes input as capability mask expressed as two comma separated hex
u32 words. The mask, however, is stored in kernel as kernel_cap_t type.
Any capabilities that are not part of this mask will be controlled

Hi Martin
Thanks for the patches. Documentation like this is often useful.

With this new notion of "controlled" user-namespaces, the controlled
user-namespaces are marked at the time of their creation while the
capabilities of processes that belong to them are controlled using the
global mask.
Init-user-ns is always uncontrolled and a process that
