pkt_sched: namespace aware act_mirred

2013-01-14T20:09:36+00:00

Eric Dumazet pointed out that act_mirred needs to find the current net_ns,
and struct net pointer is not provided in the call chain.  His original
patch made use of current->nsproxy->net_ns to find the network namespace,
but this fails to work correctly for userspace code that makes use of
netlink sockets in different network namespaces.  Instead, pass the
"struct net *" down along the call chain to where it is needed.

This version removes the ifb changes as Eric has submitted that patch
separately, but is otherwise identical to the previous version.

net: Push capable(CAP_NET_ADMIN) into the rtnl methods

2012-11-19T01:32:44+00:00

- In rtnetlink_rcv_msg convert the capable(CAP_NET_ADMIN) check
  to ns_capable(net->user-ns, CAP_NET_ADMIN).  Allowing unprivileged
  users to make netlink calls to modify their local network
  namespace.

- In the rtnetlink doit methods add capable(CAP_NET_ADMIN) so
  that calls that are not safe for unprivileged users are still
  protected.

Later patches will remove the extra capable calls from methods
that are safe for unprivilged users.

netlink: Rename pid to portid to avoid confusion

2012-09-10T19:30:41+00:00

It is a frequent mistake to confuse the netlink port identifier with a
process identifier.  Try to reduce this confusion by renaming fields
that hold port identifiers portid instead of pid.

I have carefully avoided changing the structures exported to
userspace to avoid changing the userspace API.

I have successfully built an allyesconfig kernel with this change.

pkt_sched: act_api: Move away from NLMSG_PUT().

2012-06-27T04:39:32+00:00

Move away from NLMSG_NEW() as well.

And use nlmsg_data() while we're here too.

pkt_sched: Stop using NLA_PUT*().

2012-04-01T22:11:37+00:00

These macros contain a hidden goto, and are thus extremely error
prone and make code hard to audit.

net: Fix files explicitly needing to include module.h

2011-10-31T23:30:28+00:00

With calls to modular infrastructure, these files really
needs the full module.h header.  Call it out so some of the
cleanups of implicit and unrequired includes elsewhere can be
cleaned up.

rtnetlink: Compute and store minimum ifinfo dump size

2011-06-10T03:38:07+00:00

The message size allocated for rtnl ifinfo dumps was limited to
a single page.  This is not enough for additional interface info
available with devices that support SR-IOV and caused a bug in
which VF info would not be displayed if more than approximately
40 VFs were created per interface.

Implement a new function pointer for the rtnl_register service that will
calculate the amount of data required for the ifinfo dump and allocate
enough data to satisfy the request.

net,rcu: convert call_rcu(tcf_common_free_rcu) to kfree_rcu()

2011-05-08T05:50:48+00:00

The rcu callback tcf_common_free_rcu() just calls a kfree(),
so we use kfree_rcu() instead of the call_rcu(tcf_common_free_rcu).
