net/net_namespace: Check the return value of register_pernet_subsys()

2018-12-24T22:43:27+00:00

In net_ns_init(), register_pernet_subsys() could fail while registering
network namespace subsystems. The fix checks the return value and
sends a panic() on failure.

netns: enable to dump full nsid translation table

2018-11-28T00:20:20+00:00

Like the previous patch, the goal is to ease to convert nsids from one
netns to another netns.
A new attribute (NETNSA_CURRENT_NSID) is added to the kernel answer when
NETNSA_TARGET_NSID is provided, thus the user can easily convert nsids.

netns: enable to specify a nsid for a get request

2018-11-28T00:20:20+00:00

Combined with NETNSA_TARGET_NSID, it enables to "translate" a nsid from one
netns to a nsid of another netns.
This is useful when using NETLINK_F_LISTEN_ALL_NSID because it helps the
user to interpret a nsid received from an other netns.

netns: add support of NETNSA_TARGET_NSID

2018-11-28T00:20:20+00:00

Like it was done for link and address, add the ability to perform get/dump
in another netns by specifying a target nsid attribute.

netns: introduce 'struct net_fill_args'

2018-11-28T00:20:20+00:00

This is a preparatory work. To avoid having to much arguments for the
function rtnl_net_fill(), a new structure is defined.

This argument is not used anymore.

net/namespace: Update rtnl_net_dumpid for strict data checking

2018-10-08T17:39:05+00:00

Update rtnl_net_dumpid for strict data checking. If the flag is set,
the dump request is expected to have an rtgenmsg struct as the header
which has the family as the only element. No data may be appended.

Merge branch 'ida-4.19' of git://git.infradead.org/users/willy/linux-dax

Pull IDA updates from Matthew Wilcox:
 "A better IDA API:

      id = ida_alloc(ida, GFP_xxx);
      ida_free(ida, id);

  rather than the cumbersome ida_simple_get(), ida_simple_remove().

  The new IDA API is similar to ida_simple_get() but better named.  The
  internal restructuring of the IDA code removes the bitmap
  preallocation nonsense.

  I hope the net -200 lines of code is convincing"
