2010-07-08bridge: Clear IPCB before possible entry into IP stackHerbert Xu1-0/+3
The bridge protocol lives dangerously by having incestuous relations with the IP stack. In this instance an abomination has been created where a bogus IPCB area from a bridged packet leads to a crash in the IP stack because it's interpreted as IP options. This patch papers over the problem by clearing the IPCB area in that particular spot. To fix this properly we'd also need to parse any IP options if present but I'm way too lazy for that.

2010-07-06net: Fix definition of netif_vdbg() when VERBOSE_DEBUG is definedBen Hutchings1-1/+1
netif_vdbg() was originally defined as entirely equivalent to netdev_vdbg(), but I assume that it was intended to take the same parameters as netif_dbg() etc. (Currently it is only used by the sfc driver, in which I worked on that assumption.) In commit a4ed89c I changed the definition used when VERBOSE_DEBUG is not defined, but I failed to notice that the definition used when VERBOSE_DEBUG is defined was also not as I expected. Change that to match netif_dbg() as well. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-07-03s2io: resolve statistics issuesJon Mason2-41/+64
This patch resolves a number of issues in the statistics gathering of the s2io driver. On Xframe adapters, the received multicast statistics counter includes pause frames which are not indicated to the driver. This can cause issues where the multicast packet count is higher than what has actually been received, possibly higher than the number of packets received. The driver software counters are replaced with the adapter hardware statistics for rx_packets, rx_bytes, and tx_bytes. It also uses the overflow registers to determine if the statistics wrapped the 32bit register (removing the window of having a statistic value less than the previous call). rx_length_errors statistic now includes undersized packets in addition to oversized packets in its counting. Finally, rx_crc_errors are now being counted. Signed-off-by: Jon Mason <jon.mason@exar.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-07-03net: decreasing real_num_tx_queues needs to flush qdiscJohn Fastabend4-5/+30
Reducing real_num_queues needs to flush the qdisc otherwise skbs with queue_mappings greater then real_num_tx_queues can be sent to the underlying driver. The flow for this is, dev_queue_xmit() dev_pick_tx() skb_tx_hash() => hash using real_num_tx_queues skb_set_queue_mapping() ... qdisc_enqueue_root() => enqueue skb on txq from hash ... dev->real_num_tx_queues -= n ... sch_direct_xmit() dev_hard_start_xmit() ndo_start_xmit(skb,dev) => skb queue set with old hash skbs are enqueued on the qdisc with skb->queue_mapping set 0 < queue_mappings < real_num_tx_queues. When the driver decreases real_num_tx_queues skb's may be dequeued from the qdisc with a queue_mapping greater then real_num_tx_queues. This fixes a case in ixgbe where this was occurring with DCB and FCoE. Because the driver is using queue_mapping to map skbs to tx descriptor rings we can potentially map skbs to rings that no longer exist.

2010-07-01bonding: check if clients MAC addr has changedFlavio Leitner1-1/+2
When two systems using bonding devices in adaptive load balancing (ALB) communicates with each other, an endless ping-pong of ARP replies starts between these two systems. What happens? In the ALB mode, bonding driver keeps track of each client connected in a hash table, so it can do the receive load balancing (RLB). This hash table is updated when an ARP reply is received, then it scans for the client entry, updates its MAC address and flag it to be announced later. Therefore, two seconds later, the alb monitor runs and send for each updated client entry two ARP replies updating this specific client. The same process happens on the receiving system, causing the endless ping-pong of arp replies. See more information including the relevant functions below: System 1 System 2 bond0 bond0 ping <system2> ARP request ---------> <--------- ARP reply +->rlb_arp_recv <---------------------+ <--- loop begins | rlb_update_entry_from_arp | | client_info->ntt = 1; | | bond_info->rx_ntt = 1; | | | | <communication succeed> | | | | bond_alb_monitor | | rlb_update_rx_clients | | rlb_update_client | | arp_create(ARPOP_REPLY) | | send ARP reply --------------> V | send ARP reply --------------> | rlb_arp_recv | rlb_update_entry_from_arp | client_info->ntt = 1; | bond_info->rx_ntt = 1; | < snipped, same as in system 1> +------- <-------------- send ARP reply <-------------- send ARP reply Besides the unneeded networking traffic, this loop breaks a cluster because a backup system can't take over the IP address. There is always one system sending an ARP reply poisoning the network. This patch fixes the problem adding a check for the MAC address before updating it. Thus, if the MAC address didn't change, there is no need to update neither to announce it later.

2010-06-29ethtool: Fix potential user buffer overflow for ETHTOOL_{G, S}RXFHBen Hutchings2-9/+29
struct ethtool_rxnfc was originally defined in 2.6.27 for the ETHTOOL_{G,S}RXFH command with only the cmd, flow_type and data fields. It was then extended in 2.6.30 to support various additional commands. These commands should have been defined to use a new structure, but it is too late to change that now. Since user-space may still be using the old structure definition for the ETHTOOL_{G,S}RXFH commands, and since they do not need the additional fields, only copy the originally defined fields to and from user-space.

The addition of TLLAO option created a kernel OOPS regression for the case where neighbor advertisement is being sent via proxy path. When using proxy, ipv6_get_ifaddr() returns NULL causing the NULL dereference. Change causing the bug was: commit f7734fdf61ec6bb848e0bafc1fb8bad2c124bb50 Author: Octavian Purdila <opurdila@ixiacom.com> Date: Fri Oct 2 11:39:15 2009 +0000 make TLLAO option for NA packets configurable Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Acked-by: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org> Signed-off-by: David S.

2010-06-26iwlwifi: set TX_CMD_FLAG_PROT_REQUIRE_MSK in tx_flagWey-Yi Guy1-5/+1
When building tx command, always set TX_CMD_FLAG_PROT_REQUIRE_MSK for 5000 series and up. Without setting this bit the firmware will not examine the RTS/CTS setting and thus not send traffic with the appropriate protection. RTS/CTS is is required for HT traffic in a noisy environment where, without this setting, connections will stall on some hardware as documented in the patch that initially attempted to address this: commit 1152dcc28c66a74b5b3f1a3ede0aa6729bfd48e4 Author: Wey-Yi Guy <wey-yi.w.guy@intel.com> Date: Fri Jan 15 13:42:58 2010 -0800 iwlwifi: Fix throughput stall issue in HT mode for 5000 Similar to 6000 and 1000 series, RTS/CTS is the recommended protection mechanism for 5000 series in HT mode based on the HW design. Using RTS/CTS will better protect the inner exchange from interference, especially in highly-congested environment, it also prevent uCode encounter TX FIFO underrun and other HT mode related performance issues. For 3945 and 4965, different flags are used for RTS/CTS or CTS-to-Self protection. Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com>
