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'
with 'media' in all function names, variable names, and prefixes
where this is what really is meant.

Note that this change is cosmetic only, and no runtime behaviour

tipc: don't use memcpy to copy from user space

tipc_msg_build() calls skb_copy_to_linear_data_offset() to copy data
from user space to kernel space. However, the latter function does
in its turn call memcpy() to perform the actual copying. This poses
an obvious security and robustness risk, since memcpy() never makes
any validity check on the pointer it is copying from.

To correct this, we the replace the offending function call with

Merge branch 'net-next' of git://git./linux/kernel/git/pablo/nftables

Pablo Neira Ayuso says:

====================
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!

11 years agonetfilter: nfnetlink: add batch support and use it from nf_tables
Pablo Neira Ayuso [Mon, 14 Oct 2013 09:05:33 +0000 (11:05 +0200)]
netfilter: nfnetlink: add batch support and use it from nf_tables

This patch adds a batch support to nfnetlink. Basically, it adds
two new control messages:

* NFNL_MSG_BATCH_BEGIN, that indicates the beginning of a batch,
  the nfgenmsg->res_id indicates the nfnetlink subsystem ID.

* NFNL_MSG_BATCH_END, that results in the invocation of the
  ss->commit callback function. If not specified or an error
  ocurred in the batch, the ss->abort function is invoked
  instead.

The end message represents the commit operation in nftables, the
lack of end message results in an abort. This patch also adds the
.call_batch function that is only called from the batch receival
path.

This patch adds atomic rule updates and dumps based on
bitmask generations. This allows to atomically commit a set of
rule-set updates incrementally without altering the internal
state of existing nf_tables expressions/matches/targets.

The idea consists of using a generation cursor of 1 bit and
a bitmask of 2 bits per rule. Assuming the gencursor is 0,
then the genmask (expressed as a bitmask) can be interpreted
as:

00 active in the present, will be active in the next generation.
01 inactive in the present, will be active in the next generation.
10 active in the present, will be deleted in the next generation.
 ^
 gencursor

Once you invoke the transition to the next generation, the global
gencursor is updated:

00 active in the present, will be active in the next generation.
01 active in the present, needs to zero its future, it becomes 00.
10 inactive in the present, delete now.
^
gencursor

If a dump is in progress and nf_tables enters a new generation,
the dump will stop and return -EBUSY to let userspace know that
it has to retry again. In order to invalidate dumps, a global
genctr counter is increased everytime nf_tables enters a new
generation.

This new operation can be used from the user-space utility
that controls the firewall, eg.

nft -f restore

The rule updates contained in `file' will be applied atomically.

cat file
-----
add filter INPUT ip saddr 1.1.1.1 counter accept #1
del filter INPUT ip daddr 2.2.2.2 counter drop   #2
-EOF-

Note that the rule 1 will be inactive until the transition to the
next generation, the rule 2 will be evicted in the next generation.

There is a penalty during the rule update due to the branch
misprediction in the packet matching framework. But that should be
quickly resolved once the iteration over the commit list that
contain rules that require updates is finished.

Event notification happens once the rule-set update has been
committed. So we skip notifications is case the rule-set update
is aborted, which can happen in case that the rule-set is tested
to apply correctly.

This patch squashed the following patches from Pablo:

* nf_tables: atomic rule updates and dumps
* nf_tables: get rid of per rule list_head for commits
* nf_tables: use per netns commit list
* nfnetlink: add batch support and use it from nf_tables
* nf_tables: all rule updates are transactional
* nf_tables: attach replacement rule after stale one
* nf_tables: do not allow deletion/replacement of stale rules
* nf_tables: remove unused NFTA_RULE_FLAGS

By providing the create command and specifying the position, the
rule is inserted after the rule with the handle equal to the
provided position.

Regarding notification, the position attribute specifies the
handle of the previous rule to make sure we don't point to any
stale rule in notifications coming from the commit path.
