rtnl_getlink() & rtnl_setlink() run with RTNL held, we can use __dev_get_by_index() and __dev_get_by_name() variants and avoid dev_hold()/dev_put() Adds to rtnl_getlink() the capability to find a device by its name, not only by its index. Signed-off-by:

For connected sockets, the first run of dev_pick_tx saves the calculated txq in sk_tx_queue_mapping. This is not saved if either the device has a queue select or the socket is not connected. Next iterations of dev_pick_tx uses the cached value of sk_tx_queue_mapping. Signed-off-by:

dst_negative_advice() should check for changed dst and reset sk_tx_queue_mapping accordingly. Pass sock to the callers of dst_negative_advice. (sk_reset_txq is defined just for use by dst_negative_advice. The only way I could find to get around this is to move dst_negative_() from dst.h to dst.c, include sock.h in dst.c, etc) Signed-off-by:

IPv6: Reset sk_tx_queue_mapping when dst_cache is reset. Use existing macro to do the work. Signed-off-by:

Krishna Kumar authored
Introduce sk_tx_queue_mapping; and functions that set, test and get this value. Reset sk_tx_queue_mapping to -1 whenever the dst cache is set/reset, and in socket alloc. Setting txq to -1 and using valid txq=<0 to n-1> allows the tx path to use the value of sk_tx_queue_mapping directly instead of subtracting 1 on every tx. Signed-off-by:

It can help being able to filter packets on their queue_mapping. If filter performance is not good, we could add a "numqueue" field in struct packet_type, so that netif_nit_deliver() and other functions can directly ignore packets with not expected queue number. Lets experiment this simple filter extension first. Signed-off-by:

While doing multiple captures, I found af_packet was dirtying cache line containing its prot_hook. This slow down machines where several cpus are necessary to handle capture traffic, as each prot_hook is traversed for each packet coming in or out the host. This patches moves "struct packet_type prot_hook" to the end of packet_sock, and uses a ____cacheline_aligned_in_smp to make sure this remains shared by all cpus. Signed-off-by:

This patch makes the private functions alloc_can_skb() and alloc_can_err_skb() of the at91_can driver public and adapts all drivers to use these. While making the patch I realized, that the skb's are *not* setup consistently. It's now done as shown below: skb->protocol = htons(ETH_P_CAN); skb->pkt_type = PACKET_BROADCAST; skb->ip_summed = CHECKSUM_UNNECESSARY; *cf = (struct can_frame *)skb_put(skb, sizeof(struct can_frame)); memset(*cf, 0, sizeof(struct can_frame)); The frame is zeroed out to avoid uninitialized data to be passed to user space. Some drivers or library code did not set "pkt_type" or "ip_summed". Also, "__constant_htons()" should not be used for runtime invocations, as pointed out by David Miller. Signed-off-by:

This patch adds Intel Wireless MultiCom 3200 top driver. IWMC3200 is 4Wireless Com CHIP (GPS/BT/WiFi/WiMAX). Top driver is responsible for device initialization and firmware download. Firmware handled by top is responsible for top itself and as well as bluetooth and GPS coms. (Wifi and WiMax provide their own firmware) In addition top driver is used to retrieve firmware logs and supports other debugging features Signed-off-by:

In order to have better cache layouts of struct sock (separate zones for rx/tx paths), we need this preliminary patch. Goal is to transfert fields used at lookup time in the first read-mostly cache line (inside struct sock_common) and move sk_refcnt to a separate cache line (only written by rx path) This patch adds inet_ prefix to daddr, rcv_saddr, dport, num, saddr, sport and id fields. This allows a future patch to define these fields as macros, like sk_refcnt, without name clashes. Signed-off-by:

1. GENL_MIN_ID is a valid id -> no need to start at GENL_MIN_ID + 1. 2. Avoid going through the ids two times: If we start at GENL_MIN_ID+1 (*or bigger*) and all ids are over!, the code iterates through the list twice (*or lesser*). 3. Simplify code - no need to start at idx=0 which gets reset to GENL_MIN_ID. Patch on net-next-2.6. Reboot test shows that first id passed to genl_register_family was 16, next two were GENL_ID_GENERATE and genl_generate_id returned 17 & 18 (user level testing of same code shows expected values across entire range of MIN/MAX).
