Fix to return a negative error code from the error handling
case instead of 0, as returned elsewhere in function

ipvs: remove extra rcu lock

2013-03-19T12:21:52+00:00

In 3.7 we added code that uses ipv4_update_pmtu but after commit
c5ae7d4192 (ipv4: must use rcu protection while calling fib_lookup)
the RCU lock is not needed.

ipvs: add backup_only flag to avoid loops

2013-03-19T12:21:51+00:00

Dmitry Akindinov is reporting for a problem where SYNs are looping
between the master and backup server when the backup server is used as
real server in DR mode and has IPVS rules to function as director.

Even when the backup function is enabled we continue to forward
traffic and schedule new connections when the current master is using
the backup server as real server. While this is not a problem for NAT,
for DR and TUN method the backup server can not determine if a request
comes from client or from director.

To avoid such loops add new sysctl flag backup_only. It can be needed
for DR/TUN setups that do not need backup and director function at the
same time. When the backup function is enabled we stop any forwarding
and pass the traffic to the local stack (real server mode). The flag
disables the director function when the backup function is enabled.

For setups that enable backup function for some virtual services and
director function for other virtual services there should be another
more complex solution to support DR/TUN mode, may be to assign
per-virtual service syncid value, so that we can differentiate the
requests.

ipvs: fix sctp chunk length order

2013-03-19T00:37:27+00:00

Fix wrong but non-fatal access to chunk length.
sch->length should be in network order, next chunk should
be aligned to 4 bytes. Problem noticed in sparse output.

netfilter: nfnetlink_queue: fix incorrect initialization of copy range field

2013-03-15T11:35:49+00:00

2^16 = 0xffff, not 0xfffff (note the extra 'f'). Not dangerous since you
adjust it to min_t(data_len, skb->len) just after on.

netfilter: nf_conntrack: register pernet subsystem before register L4 proto

2013-03-15T11:29:25+00:00

In (c296bb4 netfilter: nf_conntrack: refactor l4proto support for netns)
the l4proto gre/dccp/udplite/sctp registration happened before the pernet
subsystem, which is wrong.

Register pernet subsystem before register L4proto since after register
L4proto, init_conntrack may try to access the resources which allocated
in register_pernet_subsys.

Pull networking fixes from David Miller:
 "A moderately sized pile of fixes, some specifically for merge window
  introduced regressions although others are for longer standing items
  and have been queued up for -stable.

  I'm kind of tired of all the RDS protocol bugs over the years, to be
  honest, it's way out of proportion to the number of people who
  actually use it.

   1) Fix missing range initialization in netfilter IPSET, from Jozsef
      Kadlecsik.

   2) ieee80211_local->tim_lock needs to use BH disabling, from Johannes
      Berg.

   3) Fix DMA syncing in SFC driver, from Ben Hutchings.

   4) Fix regression in BOND device MAC address setting, from Jiri
      Pirko.

   5) Missing usb_free_urb in ISDN Hisax driver, from Marina Makienko.

   6) Fix UDP checksumming in bnx2x driver for 57710 and 57711 chips,
      fix from Dmitry Kravkov.

   7) Missing cfgspace_lock initialization in BCMA driver.

   8) Validate parameter size for SCTP assoc stats getsockopt(), from
      Guenter Roeck.

   9) Fix SCTP association hangs, from Lee A Roberts.

  10) Fix jumbo frame handling in r8169, from Francois Romieu.

  11) Fix phy_device memory leak, from Petr Malat.

  12) Omit trailing FCS from frames received in BGMAC driver, from Hauke
      Mehrtens.

  13) Missing socket refcount release in L2TP, from Guillaume Nault.

  14) sctp_endpoint_init should respect passed in gfp_t, rather than use
      GFP_KERNEL unconditionally.  From Dan Carpenter.

  15) Add AISX AX88179 USB driver, from Freddy Xin.

  16) Remove MAINTAINERS entries for drivers deleted during the merge
      window, from Cesar Eduardo Barros.

  17) RDS protocol can try to allocate huge amounts of memory, check
      that the user's request length makes sense, from Cong Wang.

  18) SCTP should use the provided KMALLOC_MAX_SIZE instead of it's own,
      bogus, definition.  From Cong Wang.

  19) Fix deadlocks in FEC driver by moving TX reclaim into NAPI poll,
      from Frank Li.  Also, fix a build error introduced in the merge
      window.

  20) Fix bogus purging of default routes in ipv6, from Lorenzo Colitti.

  21) Don't double count RTT measurements when we leave the TCP receive
      fast path, from Neal Cardwell."
