This patch changes the type of the third parameter 'length' of the raw_send_hdrinc() function from 'int' to 'size_t'. This makes sense since this function is only ever called from one location, and the value passed as the third parameter in that location is itself of type size_t, so this makes the recieving functions parameter type match. Also, inside raw_send_hdrinc() the 'length' variable is used in comparisons with unsigned values and passed as parameter to functions expecting unsigned values (it's used in a single comparison with a signed value, but that one can never actually be negative so the patch also casts that one to size_t to stop gcc worrying, and it is passed in a single instance to memcpy_fromiovecend() which expects a signed int, but as far as I can see that's not a problem since the value of 'length' shouldn't ever exceed the value of a signed int).

This patch changes the type of the local variable 'i' in raw_probe_proto_opt() from 'int' to 'unsigned int'. The only use of 'i' in this function is as a counter in a for() loop and subsequent index into the msg->msg_iov[] array. Since 'i' is compared in a loop to the unsigned variable msg->msg_iovlen gcc -W generates this warning : net/ipv4/raw.c:340: warning: comparison between signed and unsigned Changing 'i' to unsigned silences this warning and is safe since the array index can never be negative anyway, so unsigned int is the logical type to use for 'i' and also enables a larger msg_iov[] array (but I don't know if that will ever matter).

This patch gets rid of the following gcc -W warning in net/ipv4/raw.c : net/ipv4/raw.c:387: warning: comparison of unsigned expression < 0 is always false Since 'len' is of type size_t it is unsigned and can thus never be <0, and since this is obvious from the function declaration just a few lines above I think it's ok to remove the pointless check for len<0.

This patch silences these two gcc -W warnings in net/ipv4/raw.c : net/ipv4/raw.c:517: warning: signed and unsigned type in conditional expression net/ipv4/raw.c:613: warning: signed and unsigned type in conditional expression It doesn't change the behaviour of the code, simply writes the conditional expression with plain 'if()' syntax instead of '? :' , but since this breaks it into sepperate statements gcc no longer complains about having both a signed and unsigned value in the same conditional expression.

Implements an interface to be used by leaf qdiscs maintaining an internal skb queue. The interface maintains a backlog in bytes additionaly to the skb_queue_len() maintained by the queue itself. Relevant statistics get incremented automatically. Every function comes in two variants, one assuming Qdisc->q is used as queue and the second taking a sk_buff_head as argument. Be aware that, if you use multiple queues, you still have to maintain the Qdisc->q.qlen counter yourself. Signed-off-by: NThomas Graf <tgraf@suug.ch> Signed-off-by: NDavid S.

This patch replaces the spin_lock_irqsave call on the receive queue lock in SCTP with spin_lock_bh. Despite the proliferation of spin_lock_irqsave calls in this stack, it is only entered from the IPv4/IPv6 stack and user space. That is, it is never entered from hardirq context. The call in question is only called from recvmsg which means that IRQs aren't disabled. Therefore it is safe to replace it with spin_lock_bh.

In light of my recent patch to net/ipv4/udp.c that replaced the spin_lock_irq calls on the receive queue lock with spin_lock_bh, here is a similar patch for all other occurences of spin_lock_irq on receive/error queue locks in IPv4 and IPv6. In these stacks, we know that they can only be entered from user or softirq context. Therefore it's safe to disable BH only.

This patch changes the format of the XFRM_MSG_DELSA and XFRM_MSG_DELPOLICY notification so that the main message sent is of the same format as that received by the kernel if the original message was via netlink. This also means that we won't lose the byid information carried in km_event. Since this user interface is introduced by Jamal's patch we can still afford to change it.

Introduces a new macro NLMSG_NEW which extends NLMSG_PUT but takes a flags argument. NLMSG_PUT stays there for compatibility but now calls NLMSG_NEW with flags == 0. NLMSG_PUT_ANSWER is renamed to NLMSG_NEW_ANSWER which now also takes a flags argument. Also converts the users of NLMSG_PUT_ANSWER to use NLMSG_NEW_ANSWER and fixes the two direct users of __nlmsg_put to either provide the flags or use NLMSG_NEW(_ANSWER).

To retrieve the neighbour tables send RTM_GETNEIGHTBL with the NLM_F_DUMP flag set. Every neighbour table configuration is spread over multiple messages to avoid running into message size limits on systems with many interfaces. The first message in the sequence transports all not device specific data such as statistics, configuration, and the default parameter set. This message is followed by 0..n messages carrying device specific parameter sets. Although the ordering should be sufficient, NDTA_NAME can be used to identify sequences. The initial message can be identified by checking for NDTA_CONFIG. The device specific messages do not contain this TLV but have NDTPA_IFINDEX set to the corresponding interface index. To change neighbour table attributes, send RTM_SETNEIGHTBL with NDTA_NAME set. Changeable attribute include NDTA_THRESH[1-3], NDTA_GC_INTERVAL, and all TLVs in NDTA_PARMS unless marked otherwise. Device specific parameter sets can be changed by setting NDTPA_IFINDEX to the interface index of the corresponding device. Signed-off-by: NThomas Graf <tgraf@suug.ch> Signed-off-by: NDavid S.
