ipvs: fix AF assignment in ip_vs_conn_new()

2014-02-04T12:13:47Z

If a fwmark is passed to ip_vs_conn_new(), it is passed in vaddr, not daddr. Therefore we should set AF to AF_UNSPEC in vaddr assignment (like we do in ip_vs_ct_in_get()), otherwise we may copy only first 4 bytes of an IPv6 address into cp->daddr.

net: replace macros net_random and net_srandom with direct calls to prandom

2014-01-14T23:15:25Z

This patch removes the net_random and net_srandom macros and replaces them with direct calls to the prandom ones. As new commits only seem to use prandom_u32 there is no use to keep them around. This change makes it easier to grep for users of prandom_u32. Signed-off-by: Aruna-Hewapathirane Suggested-by: Hannes Frederic Sowa Acked-by: Hannes Frederic Sowa Signed-off-by: David S. Miller

ipvs: correct usage/allocation of seqadj ext in ipvs

2013-12-27T03:30:02Z

The IPVS FTP helper ip_vs_ftp could trigger an OOPS in nf_ct_seqadj_set, after commit 41d73ec053d2 (netfilter: nf_conntrack: make sequence number adjustments usuable without NAT). This is because, the seqadj ext is now allocated dynamically, and the IPVS code didn't handle this situation. Fix this in the IPVS nfct code by invoking the alloc function nfct_seqadj_ext_add().

ipvs: Remove unused variable ret from sync_thread_master()

2013-12-27T03:19:32Z

net/netfilter/ipvs/ip_vs_sync.c: In function 'sync_thread_master': net/netfilter/ipvs/ip_vs_sync.c:1640:8: warning: unused variable 'ret' [-Wunused-variable] Commit 35a2af94c7ce7130ca292c68b1d27fcfdb648f6b ("sched/wait: Make the __wait_event*() interface more friendly") changed how the interruption state is returned. However, sync_thread_master() ignores this state, now causing a compile warning. According to Julian Anastasov , this behavior is OK: "Yes, your patch looks ok to me. In the past we used ssleep() but IPVS users were confused why IPVS threads increase the load average. So, we switched to _interruptible calls and later the socket polling was added." Document this, as requested by Peter Zijlstra, to avoid precious developers disappearing in this pitfall in the future.

netfilter: Fix FSF address in file headers

2013-12-06T17:37:57Z

Several files refer to an old address for the Free Software Foundation in the file header comment. Resolve by replacing the address with the URL so that we do not have to keep updating the header comments anytime the address changes.

Pull networking fixes from David Miller: "Mostly these are fixes for fallout due to merge window changes, as well as cures for problems that have been with us for a much longer period of time" 1) Johannes Berg noticed two major deficiencies in our genetlink registration. Some genetlink protocols we passing in constant counts for their ops array rather than something like ARRAY_SIZE(ops) or similar. Also, some genetlink protocols were using fixed IDs for their multicast groups. We have to retain these fixed IDs to keep existing userland tools working, but reserve them so that other multicast groups used by other protocols can not possibly conflict. In dealing with these two problems, we actually now use less state management for genetlink operations and multicast groups. 2) When configuring interface hardware timestamping, fix several drivers that simply do not validate that the hwtstamp_config value is one the driver actually supports. From Ben Hutchings. 3) Invalid memory references in mwifiex driver, from Amitkumar Karwar. 4) In dev_forward_skb(), set the skb->protocol in the right order relative to skb_scrub_packet(). From Alexei Starovoitov. 5) Bridge erroneously fails to use the proper wrapper functions to make calls to netdev_ops->ndo_vlan_rx_{add,kill}_vid. Fix from Toshiaki Makita. 6) When detaching a bridge port, make sure to flush all VLAN IDs to prevent them from leaking, also from Toshiaki Makita. 7) Put in a compromise for TCP Small Queues so that deep queued devices that delay TX reclaim non-trivially don't have such a performance decrease. One particularly problematic area is 802.11 AMPDU in wireless. From Eric Dumazet. 8) Fix crashes in tcp_fastopen_cache_get(), we can see NULL socket dsts here. Fix from Eric Dumzaet, reported by Dave Jones. 9) Fix use after free in ipv6 SIT driver, from Willem de Bruijn. 10) When computing mergeable buffer sizes, virtio-net fails to take the virtio-net header into account. From Michael Dalton. 11) Fix seqlock deadlock in ip4_datagram_connect() wrt. statistic bumping, this one has been with us for a while. From Eric Dumazet. 12) Fix NULL deref in the new TIPC fragmentation handling, from Erik Hugne. 13) 6lowpan bit used for traffic classification was wrong, from Jukka Rissanen. 14) macvlan has the same issue as normal vlans did wrt. propagating LRO disabling down to the real device, fix it the same way. From Michal Kubecek. 15) CPSW driver needs to soft reset all slaves during suspend, from Daniel Mack. 16) Fix small frame pacing in FQ packet scheduler, from Eric Dumazet. 17) The xen-netfront RX buffer refill timer isn't properly scheduled on partial RX allocation success, from Ma JieYue. 18) When ipv6 ping protocol support was added, the AF_INET6 protocol initialization cleanup path on failure was borked a little. Fix from Vlad Yasevich. 19) If a socket disconnects during a read/recvmsg/recvfrom/etc that blocks we can do the wrong thing with the msg_name we write back to userspace. From Hannes Frederic Sowa. There is another fix in the works from Hannes which will prevent future problems of this nature. 20) Fix route leak in VTI tunnel transmit, from Fan Du. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (106 commits) genetlink: make multicast groups const, prevent abuse genetlink: pass family to functions using groups genetlink: add and use genl_set_err() genetlink: remove family pointer from genl_multicast_group genetlink: remove genl_unregister_mc_group() hsr: don't call genl_unregister_mc_group() quota/genetlink: use proper genetlink multicast APIs drop_monitor/genetlink: use proper genetlink multicast APIs genetlink: only pass array to genl_register_family_with_ops() tcp: don't update snd_nxt, when a socket is switched from repair mode atm: idt77252: fix dev refcnt leak xfrm: Release dst if this dst is improper for vti tunnel netlink: fix documentation typo in netlink_set_err() be2net: Delete secondary unicast MAC addresses during be_close be2net: Fix unconditional enabling of Rx interface options net, virtio_net: replace the magic value ping: prevent NULL pointer dereference on write to msg_name bnx2x: Prevent "timeout waiting for state X" bnx2x: prevent CFC attention bnx2x: Prevent panic during DMAE timeout ...

genetlink: only pass array to genl_register_family_with_ops()

2013-11-19T21:39:05Z

As suggested by David Miller, make genl_register_family_with_ops() a macro and pass only the array, evaluating ARRAY_SIZE() in the macro, this is a little safer. The openvswitch has some indirection, assing ops/n_ops directly in that code. This might ultimately just assign the pointers in the family initializations, saving the struct genl_family_and_ops and code (once mcast groups are handled differently.)

genetlink: make all genl_ops users const

2013-11-14T22:10:41Z

Now that genl_ops are no longer modified in place when registering, they can be made const. This patch was done mostly with spatch: @@ identifier ops; @@ +const struct genl_ops ops[] = { ... }; (except the struct thing in net/openvswitch/datapath.c) Signed-off-by: Johannes Berg Signed-off-by: David S.
