TIPC 'bearer' exists as an abstract concept, while 'media'
is deemed a specific implementation of a bearer, such as Ethernet
or Infiniband media. When a component inside TIPC wants to control
a specific media, it only needs to access the generic bearer API
to achieve this. However, in the current media implementations,
the 'bearer' name is also extensively used in media specific
function and variable names.
This may create confusion, so we choose to replace the term 'bearer'

Since commit
0998d0631001288a5974afc0b2a5f568bcdecb4d
(device-core: Ensure drvdata = NULL when no driver is bound),
the driver core clears the driver data to NULL after device_release
or on probe failure. Thus, it is not needed to manually clear the
device driver data to NULL.

====================
netfilter updates: nf_tables pull request
The following patchset contains the current original nf_tables tree
condensed in 17 patches. I have organized them by chronogical order
since the original nf_tables code was released in 2009 and by
dependencies between the different patches.
The patches are:
1) Adapt all existing hooks in the tree to pass hook ops to the
hook callback function, required by nf_tables, from Patrick McHardy.
2) Move alloc_null_binding to nf_nat_core, as it is now also needed by
nf_tables and ip_tables, original patch from Patrick McHardy but
required major changes to adapt it to the current tree that I made.
3) Add nf_tables core, including the netlink API, the packet filtering
engine, expressions and built-in tables, from Patrick McHardy. This
patch includes accumulated fixes since 2009 and minor enhancements.
The patch description contains a list of references to the original
patches for the record. For those that are not familiar to the
original work, see [1], [2] and [3].
4) Add netlink set API, this replaces the original set infrastructure
to introduce a netlink API to add/delete sets and to add/delete
set elements. This includes two set types: the hash and the rb-tree
sets (used for interval based matching). The main difference with
ipset is that this infrastructure is data type agnostic. Patch from
Patrick McHardy.
5) Allow expression operation overload, this API change allows us to
provide define expression subtypes depending on the configuration
that is received from user-space via Netlink. It is used by follow
up patches to provide optimized versions of the payload and cmp
expressions and the x_tables compatibility layer, from Patrick
McHardy.
6) Add optimized data comparison operation, it requires the previous
patch, from Patrick McHardy.
7) Add optimized payload implementation, it requires patch 5, from
Patrick McHardy.
8) Convert built-in tables to chain types. Each chain type have special
semantics (filter, route and nat) that are used by userspace to
configure the chain behaviour. The main chain regarding iptables
is that tables become containers of chain, with no specific semantics.
However, you may still configure your tables and chains to retain
iptables like semantics, patch from me.
9) Add compatibility layer for x_tables. This patch adds support to
use all existing x_tables extensions from nf_tables, this is used
to provide a userspace utility that accepts iptables syntax but
used internally the nf_tables kernel core. This patch includes
missing features in the nf_tables core such as the per-chain
stats, default chain policy and number of chain references, which
are required by the iptables compatibility userspace tool. Patch
from me.
10) Fix transport protocol matching, this fix is a side effect of the
x_tables compatibility layer, which now provides a pointer to the
transport header, from me.
11) Add support for dormant tables, this feature allows you to disable
all chains and rules that are contained in one table, from me.
12) Add IPv6 NAT support. At the time nf_tables was made, there was no
NAT IPv6 support yet, from Tomasz Bursztyka.
13) Complete net namespace support. This patch register the protocol
family per net namespace, so tables (thus, other objects contained
in tables such as sets, chains and rules) are only visible from the
corresponding net namespace, from me.
14) Add the insert operation to the nf_tables netlink API, this requires
adding a new position attribute that allow us to locate where in the
ruleset a rule needs to be inserted, from Eric Leblond.
15) Add rule batching support, including atomic rule-set updates by
using rule-set generations. This patch includes a change to nfnetlink
to include two new control messages to indicate the beginning and
the end of a batch. The end message is interpreted as the commit
message, if it's missing, then the rule-set updates contained in the
batch are aborted, from me.
16) Add trace support to the nf_tables packet filtering core, from me.
17) Add ARP filtering support, original patch from Patrick McHardy, but
adapted to fit into the chain type infrastructure. This was recovered
to be used by nft userspace tool and our compatibility arptables
userspace tool.
There is still work to do to fully replace x_tables [4] [5] but that can
be done incrementally by extending our netlink API. Moreover, looking at
netfilter-devel and the amount of contributions to nf_tables we've been
getting, I think it would be good to have it mainstream to avoid accumulating
large patchsets skip continuous rebases.
I tried to provide a reasonable patchset, we have more than 100 accumulated
patches in the original nf_tables tree, so I collapsed many of the small
fixes to the main patch we had since 2009 and provide a small batch for
review to netdev, while trying to retain part of the history.
For those who didn't give a try to nf_tables yet, there's a quick howto
available from Eric Leblond that describes how to get things working [6].
Comments/reviews welcome.
Thanks!
