2010-09-26ipv6: add a missing unregister_pernet_subsys callNeil Horman2-3/+13
Clean up a missing exit path in the ipv6 module init routines. In addrconf_init we call ipv6_addr_label_init which calls register_pernet_subsys for the ipv6_addr_label_ops structure. But if module loading fails, or if the ipv6 module is removed, there is no corresponding unregister_pernet_subsys call, which leaves a now-bogus address on the pernet_list, leading to oopses in subsequent registrations. This patch cleans up both the failed load path and the unload path. Tested by myself with good results.

2010-09-26net: fix rcu use in ip_route_output_slowEric Dumazet1-1/+1
__in_dev_get_rtnl(dev_out) is called while RTNL is not held, thus triggers a lockdep fault. At this point, we only perform a raw test of dev_out->ip_ptr being NULL, we dont need to make sure ip_ptr cant changed right after. We can use rcu_dereference_raw() for this.

2010-09-26rps: allocate rx queues in register_netdevice onlyEric Dumazet1-44/+32
Instead of having two places were we allocate dev->_rx, introduce netif_alloc_rx_queues() helper and call it only from register_netdevice(), not from alloc_netdev_mq() Goal is to let drivers change dev->num_rx_queues after allocating netdev and before registering it.

Automatically allows vlans to get NETIF_F_HIGHDMA if underlying device supports it. On 32bit arches (and more precisely if CONFIG_HIGHMEM is enabled), it can help to reduce cost of illegal_highdma() and __skb_linearize() calls. Tested on tg3 , bnx2, bonding, this worked very well.

We have for each socket : One spinlock (sk_slock.slock) One rwlock (sk_callback_lock) Possible scenarios are : (A) (this is used in net/sunrpc/xprtsock.c) read_lock(&sk->sk_callback_lock) (without blocking BH) <BH> spin_lock(&sk->sk_slock.slock); ... read_lock(&sk->sk_callback_lock); ...

2010-09-24ip: take care of last fragment in ip_append_dataEric Dumazet1-3/+6
While investigating a bit, I found ip_fragment() slow path was taken because ip_append_data() provides following layout for a send(MTU + N*(MTU - 20)) syscall : - one skb with 1500 (mtu) bytes - N fragments of 1480 (mtu-20) bytes (before adding IP header) last fragment gets 17 bytes of trail data because of following bit: if (datalen == length + fraggap) alloclen += rt->dst.trailer_len; Then esp4 adds 16 bytes of data (while trailer_len is 17... hmm... another bug ?) In ip_fragment(), we notice last fragment is too big (1496 + 20) > mtu, so we take slow path, building another skb chain. In order to avoid taking slow path, we should correct ip_append_data() to make sure last fragment has real trail space, under mtu...

DNAT routes are always valid. 2001 * 2002 * Proxy arp feature have been extended to allow, ARP 2003 * replies back to the same interface, to support 2004 * Private VLAN switch technologies.

In order to make ipt_REJECT work with bridges, you also need to enable ip_forward. This patch also fixes a regression.

2010-09-21ip: fix truesize mismatch in ip fragmentationEric Dumazet2-11/+26
Special care should be taken when slow path is hit in ip_fragment() : When walking through frags, we transfert truesize ownership from skb to frags. Then if we hit a slow_path condition, we must undo this or risk uncharging frags->truesize twice, and in the end, having negative socket sk_wmem_alloc counter, or even freeing socket sooner than expected. Many thanks to Nick Bowler, who provided a very clean bug report and test program. Thanks to Jarek for reviewing my first patch and providing a V2 While Nick bisection pointed to commit 2b85a34e911 (net: No more expensive sock_hold()/sock_put() on each tx), underlying bug is older (2.6.12-rc5) A side effect is to extend work done in commit b2722b1c3a893e (ip_fragment: also adjust skb->truesize for packets not owned by a socket) to ipv6 as well.

2010-09-21dccp ccid-3: remove dead statesGerrit Renker2-30/+9
This patch is thanks to an investigation by Leandro Sales de Melo and his colleagues. They worked out two state diagrams which highlight the fact that the xxx_TERM states in CCID-3/4 are in fact not necessary. And this can be confirmed by in turn looking at the code: the xxx_TERM states are only ever set in ccid3_hc_{rx,tx}_exit(): when CCID-3 sets the state to xxx_TERM, it is at a time where no more processing should be going on, hence it is not necessary to introduce a dedicated exit state - this is already implied by unloading the CCID.

2010-09-21dccp: Add packet type information to CCID-specific option parsingGerrit Renker3-41/+35
This 1. adds packet type information to ccid_hc_{rx,tx}_parse_options(). This is necessary, since table 3 in RFC 4340, 5.8 leaves it to the CCIDs to state which options may (not) appear on what packet type. 2. adds such a check for CCID-3's {Loss Event, Receive} Rate as specified in RFC 4340 8.3 ("Receive Rate options MUST NOT be sent on DCCP-Data packets") and 8.5 ("Loss Event Rate options MUST NOT be sent on DCCP-Data packets"). 3. removes an unused argument `idx' from ccid_hc_{rx,tx}_parse_options(). This is also no longer necessary, since the CCID-specific option-parsing routines are passed every single parameter of the type-length-value option encoding.

2010-09-20xfrm: Allow different selector family in temporary stateThomas Egerer4-49/+67
The family parameter xfrm_state_find is used to find a state matching a certain policy. This value is set to the template's family (encap_family) right before xfrm_state_find is called. The family parameter is however also used to construct a temporary state in xfrm_state_find itself which is wrong for inter-family scenarios because it produces a selector for the wrong family. Since this selector is included in the xfrm_user_acquire structure, user space programs misinterpret IPv6 addresses as IPv4 and vice versa. This patch splits up the original init_tempsel function into a part that initializes the selector respectively the props and id of the temporary state, to allow for differing ip address families whithin the state.
