Nicolas Dichtel says: ==================== Ease to interpret net-nsid The goal of this series is to ease the interpretation of nsid received in netlink messages from other netns (when the user uses NETLINK_F_LISTEN_ALL_NSID). After this series, with a patched iproute2: $ ip netns add foo $ ip netns add bar $ touch /var/run/netns/init_net $ mount --bind /proc/1/ns/net /var/run/netns/init_net $ ip netns set init_net 11 $ ip netns set foo 12 $ ip netns set bar 13 $ ip netns init_net (id: 11) bar (id: 13) foo (id: 12) $ ip -n foo netns set init_net 21 $ ip -n foo netns set foo 22 $ ip -n foo netns set bar 23 $ ip -n foo netns init_net (id: 21) bar (id: 23) foo (id: 22) $ ip -n bar netns set init_net 31 $ ip -n bar netns set foo 32 $ ip -n bar netns set bar 33 $ ip -n bar netns init_net (id: 31) bar (id: 33) foo (id: 32) $ ip netns list-id target-nsid 12 nsid 21 current-nsid 11 (iproute2 netns name: init_net) nsid 22 current-nsid 12 (iproute2 netns name: foo) nsid 23 current-nsid 13 (iproute2 netns name: bar) $ ip -n bar netns list-id target-nsid 32 nsid 31 nsid 21 current-nsid 31 (iproute2 netns name: init_net) v3 -> v4: - patch 5/5: fix imbalance lock in error path v2 -> v3: - patch 5/5: account NETNSA_CURRENT_NSID in rtnl_net_get_size() v1 -> v2: - patch 1/5: remove net from struct rtnl_net_dump_cb - patch 2/5: new in this version - patch 3/5: use a bool to know if rtnl_get_net_ns_capable() was called - patch 5/5: use struct net_fill_args ==================== Signed-off-by: David S.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
