      netfilter: ip6t_LOG: fix a flaw in printing the MAC · 0af320fb
      由 Joerg Marx 提交于 
      The flaw was in skipping the second byte in MAC header due to increasing
the pointer AND indexed access starting at '1'.

      netfilter: tproxy: do not assign timewait sockets to skb->sk · d503b30b
      由 Florian Westphal 提交于 
      Assigning a socket in timewait state to skb->sk can trigger
kernel oops, e.g. in nfnetlink_log, which does:

if (skb->sk) {
        read_lock_bh(&skb->sk->sk_callback_lock);
        if (skb->sk->sk_socket && skb->sk->sk_socket->file) ...

in the timewait case, accessing sk->sk_callback_lock and sk->sk_socket
is invalid.

Either all of these spots will need to add a test for sk->sk_state != TCP_TIME_WAIT,
or xt_TPROXY must not assign a timewait socket to skb->sk.

This does the latter.

If a TW socket is found, assign the tproxy nfmark, but skip the skb->sk assignment,
thus mimicking behaviour of a '-m socket .. -j MARK/ACCEPT' re-routing rule.

The 'SYN to TW socket' case is left unchanged -- we try to redirect to the
listener socket.

      ipv4: Cache learned redirect information in inetpeer. · f39925db
      由 David S. Miller 提交于 
      Note that we do not generate the redirect netevent any longer,
because we don't create a new cached route.

Instead, once the new neighbour is bound to the cached route,
we emit a neigh update event instead.

      ipv4: Cache learned PMTU information in inetpeer. · 2c8cec5c
      由 David S. Miller 提交于 
      The general idea is that if we learn new PMTU information, we
bump the peer genid.

This triggers the dst_ops->check() code to validate and if
necessary propagate the new PMTU value into the metrics.

Learned PMTU information self-expires.

This means that it is not necessary to kill a cached route
entry just because the PMTU information is too old.

As a consequence:

1) When the path appears unreachable (dst_ops->link_failure
   or dst_ops->negative_advice) we unwind the PMTU state if
   it is out of date, instead of killing the cached route.

   A redirected route will still be invalidated in these
   situations.

2) rt_check_expire(), rt_worker_func(), et al. are no longer
   necessary at all.

      arp_notify: unconditionally send gratuitous ARP for NETDEV_NOTIFY_PEERS. · d11327ad
      由 Ian Campbell 提交于 
      NETDEV_NOTIFY_PEER is an explicit request by the driver to send a link
notification while NETDEV_UP/NETDEV_CHANGEADDR generate link
notifications as a sort of side effect.

In the later cases the sysctl option is present because link
notification events can have undesired effects e.g. if the link is
flapping. I don't think this applies in the case of an explicit
request from a driver.

This patch makes NETDEV_NOTIFY_PEER unconditional, if preferred we
could add a new sysctl for this case which defaults to on.

This change causes Xen post-migration ARP notifications (which cause
switches to relearn their MAC tables etc) to be sent by default.

      ROSE: AX25: finding routes simplification · 68aa3fd5
      由 Bernard Pidoux 提交于 
      With previous patch, rose_get_neigh() routine
investigates the full list of neighbor nodes
until it finds or not an already connected node whether
it is called locally or through a level 3 transit frame.
If no routes are opened through an adjacent connected node
then a classical connect request is attempted.

Then there is no more reason for an extra loop such
as the one removed by this patch.

      ROSE: rose AX25 packet routing improvement · c5d8b24a
      由 Bernard Pidoux 提交于 
      FPAC AX25 packet application is using Linux kernel ROSE
routing skills in order to connect or send packets to remote stations
knowing their ROSE address via a network of interconnected nodes.

Each FPAC node has a ROSE routing table that Linux ROSE module is
looking at each time a ROSE frame is relayed by the node or when
a connect request to a neighbor node is received.

A previous patch improved the system time response by looking at
already established routes each time the system was looking for a
route to relay a frame. If a neighbor node routing the destination
address was already connected, then the frame would be sent
through him. If not, a connection request would be issued.

The present patch extends the same routing capability to a connect
request asked by a user locally connected into an FPAC node.
Without this patch, a connect request was not well handled unless it
was directed to an immediate connected neighbor of the local node.

Implemented at a number of ROSE FPAC node stations, the present patch
improved dramatically FPAC ROSE routing time response and efficiency.

      netfilter: nf_iterate: fix incorrect RCU usage · de9963f0
      由 Patrick McHardy 提交于 
      As noticed by Eric, nf_iterate doesn't use RCU correctly by
accessing the prev pointer of a RCU protected list element when
a verdict of NF_REPEAT is issued.

Fix by jumping backwards to the hook invocation directly instead
of loading the previous list element before continuing the list
iteration.
